Abstract
Tumor hypoxia impairs the generation of reactive oxygen species and the induction of immunogenic cell death (ICD) for photodynamic therapy (PDT), thus impeding its efficacy and the subsequent immunotherapy. In addition, hypoxia plays a critical role in forming immunosuppressive tumor microenvironments (TME) by regulating the infiltration of immunosuppressive tumor-associated macrophages (TAMs) and the expression of programmed death ligand 1 (PD-L1). To simultaneously tackle these issues, a MnO2-containing albumin nanoplatform co-delivering IR780, NLG919, and a paclitaxel (PTX) dimer is designed to boost photodynamic immunotherapy. The MnO2-catalyzed oxygen supply bolsters the efficacy of PDT and PTX-mediated chemotherapy, collectively amplifying the induction of ICD and the expansion of tumor-specific cytotoxic T lymphocytes (CTLs). More importantly, hypoxia releif reshapes the immunosuppressive TME via down-regulating the intratumoral infiltration of M2-type TAMs and the PD-L1 expression of tumor cells to enhance the infiltration and efficacy of CTLs in combination with immune checkpoint blockade (ICB) by NLG919, consequently eradicating primary tumors and almost completely preventing tumor relapse and metastasis. This study sets an example of enhanced immunotherapy for breast cancers through dual ICD induction and simultaneous immunosuppression modulation via both hypoxia relief and ICB, providing a strategy for the treatment of other hypoxic and immunosuppressive cancers.

Abstract
Introduction Sepsis represents a critical medical condition that arises due to an imbalanced host reaction to infection. Central to its pathophysiology are cytokines. However, observational investigations that explore the interrelationships between circulating cytokines and susceptibility to sepsis frequently encounter challenges pertaining to confounding variables and reverse causality. Methods To elucidate the potential causal impact of cytokines on the risk of sepsis, we conducted two-sample Mendelian randomization (MR) analyses. Genetic instruments tied to circulating cytokine concentrations were sourced from genome-wide association studies encompassing 8,293 Finnish participants. We then evaluated their links with sepsis and related outcomes using summary-level data acquired from the UK Biobank, a vast multicenter cohort study involving over 500,000 European participants. Specifically, our data spanned 11,643 sepsis cases and 474,841 controls, with subsets including specific age groups, 28-day mortality, and ICU-related outcomes. Results and Discussion MR insights intimated that reduced genetically-predicted interleukin-10 (IL-10) levels causally correlated with a heightened sepsis risk (odds ratio [OR] 0.68, 95% confidence interval [CI] 0.52-0.90, P=0.006). An inverse relationship emerged between monocyte chemoattractant protein-1 (MCP-1) and sepsis-induced mortality. Conversely, elevated macrophage inflammatory protein 1 beta (MIP1B) concentrations were positively linked with both sepsis incidence and associated mortality. These revelations underscore the causal impact of certain circulating cytokines on sepsis susceptibility and its prognosis, hinting at the therapeutic potential of modulating these cytokine levels. Additional research is essential to corroborate these connections.

Abstract
Photodynamic therapy (PDT) has emerged as a powerful tumor treatment tool due to its advantages including minimal invasiveness, high selectivity and thus dampened side effects. On the other side, the efficacy of PDT is severely frustrated by the limited oxygen level in tumors, thus promoting its combination with other therapies, particularly photothermal therapy (PTT) for bolstered tumor treatment outcomes. Meanwhile, nanomedicines that could respond to various stimuli in the tumor microenvironment (TME) provide tremendous benefits for combined phototherapy with efficient hypoxia relief, tailorable drug release and activation, improved cellular uptake and intratumoral penetration of nanocarriers, etc. In this review, we will introduce the merits of combining PTT with PDT, summarize the recent important progress of combined phototherapies and their combinations with the dominant tumor treatment regimen, chemotherapy based on smart nanomedicines sensitive to various TME stimuli with a focus on their sophisticated designs, and discuss the challenges and future developments of nanomedicine-mediated combined phototherapies.

Abstract
Pathophysiological barriers in "cold" tumors seriously limit the clinical outcomes of chemoimmunotherapy. These barriers distribute in a spatial order in tumors, including immunosuppressive microenvironment, overexpressed chemokine receptors, and dense tumor mesenchyme, which require a sequential elimination in therapeutics. Herein, we reported a "dominolike" barriers elimination strategy by an intratumoral ATP supersensitive nanogel (denoted as BBLZ-945@PAC-PTX) for enhanced chemoimmunotherapy. Once it has reached the tumor site, BBLZ-945@PAC-PTX nanogel undergoes supersensitive collapse triggered by adenosine triphosphate (ATP) in perivascular regions and releases BLZ-945 conjugated albumin (BBLZ-945) to deplete tumor-associated macrophages (TAMs). Deeper spatial penetration of shrunk nanogel (PAC-PTX) could not only block CXCR4 on the cell membrane to decrease immunosuppressive cell recruitment but also internalize into tumor cells for tumor-killing and T cell priming. The strategy of "dominolike" barriers elimination in tumors enables immune cell infiltration for a potentiated immune response and offers a high-responsive treatment opinion for chemoimmunotherapy.

Abstract
The efficacy of photodynamic therapy (PDT) is severely limited by the hypoxic tumor microenvironment (TME), while the performance of PDT-aroused antitumor immunity is frustrated by the immunosuppressive TME and deficient immunogenic cell death (ICD) induction. To simultaneously tackle these pivotal problems, we herein create an albumin-based nanoplatform co-delivering IR780, NLG919 dimer and a hypoxia-activated prodrug tirapazamine (TPZ) as the dual enhancer for synergistic cancer therapy. Under NIR irradiation, IR780 generates 1O2 for PDT, which simultaneously cleaves the ROS-sensitive linker for triggered TPZ release, and activates its chemotherapy via exacerbated tumor hypoxia. Meanwhile, firstly found by us, TPZ-mediated chemotherapy boosts PDT-induced tumor ICD to evoke stronger antitumor immunity including the development of tumor-specific cytotoxic T lymphocytes (CTLs). Eventually, enriched intratumoral GSH triggers the activation of NLG919 to mitigate the immunosuppressive TME via specific indoleamine 2,3-dioxygenase 1 (IDO-1) inhibition, consequently promoting the intratumoral infiltration of CTLs and the killing of both primary and distant tumors, while the resultant memory T cells allows nearly 100% suppression of tumor recurrence and metastasis. This nanoplatform sets up an example for dully enhanced photodynamic immunotherapy of breast cancer via hypoxia-activated chemotherapy, and paves a solid way for the treatment of other hypoxic and immunosuppressive malignant tumors.

Abstract
The PI3K/AKT pathway plays an essential role in tumour development. NOD-like receptors (NLRs) regulate innate immunity and are implicated in cancer, but whether they are involved in PI3K/AKT pathway regulation is poorly understood. Here, we report that NLRP6 potentiates the PI3K/AKT pathway by binding and destabilizing p85α, the regulatory subunit of PI3K. Mechanistically, NLRP6 recruits the E3 ligase RBX1 to p85α and ubiquitinates lysine 256 on p85α, which is recognized by the autophagy cargo receptor OPTN, causing selective autophagic degradation of p85α and subsequent activation of the PI3K/AKT pathway by reducing PTEN stability. We further show that loss of NLRP6 suppresses cell proliferation, colony formation, cell migration, and tumour growth in glioblastoma cells in vitro and in vivo. Disruption of the NLRP6/p85α interaction using the Pep9 peptide inhibits the PI3K/AKT pathway and generates potent antitumour effects. Collectively, our results suggest that NLRP6 promotes p85α degradation via selective autophagy to drive tumorigenesis, and the interaction between NLRP6 and p85α can be a promising therapeutic target for tumour treatment.

Abstract
Microglia are involved in the regulation of cerebral homeostasis and pathogen confrontation. There is, however, evidence showing that excessive microglia activation is implicated in various age-related cerebral diseases. On the other hand, microglia may experience complex changes of polarization in pathological insults, i.e., from a proinflammatory M1 to an anti-inflammatory M2 phenotype, which differentially contribute to the exacerbation or alleviation of cellular injury. Remolding the phenotype of microglia or inhibiting the excessive activation of microglia seems to be a promising approach against neurodegenerative pathologies. Since δ-opioid receptor (DOR) activation exhibits a strong protective capacity against various neuronal injuries, especially the hypoxic/ischemic injury, we asked if the DOR-induced neuroprotection is associated with its effect on microglia. We explored this fundamental issue by using pharmacological and genetic approaches in the BV2 cell line, a general type of microglial cells. The results showed that DOR expression significantly increased in the activated microglial M2 phenotype, but slightly decreased in the microglial M1 phenotype. Hypoxia induced dual polarizations of BV2 cells with an increase in DOR expression. Administration of a specific DOR agonist, UFP-512, largely inhibited lipopolysaccharide (LPS) or hypoxia-induced microglial M1 activation and inflammatory activity with high concentrations of UFP-512 being effective to reverse the interleukin-4 (IL4)-induced microglial activation. Consistent with these observations, inhibiting DOR or knocking-down DOR promoted the excessive activation of BV2 cells in both M1 and M2 directions, while DOR overexpression did the opposite. Furthermore, the PC12 cells exposed to the conditioned medium of BV2 cells treated by UFP-512 grew better than those treated directly with UFP-512 under LPS or hypoxic insults. DOR inhibitor naltrindole could block all the effects of DOR activation. The medium from the BV2 cells with DOR knock-down decreased the viability of PC12 cell, while the medium from the BV2 cells with DOR overexpression largely attenuated LPS or hypoxic injury in the PC12 cells. These first data suggest a close linkage between DOR expression/function and microglial polarization and a critical role of DOR in negative controlling microglial activation. Our work provides a novel clue for new protective strategies against neurodegenerative pathophysiology through DOR-mediated regulation of microglia.

Abstract
PURPOSE Cerebral ischemia is related to insufficient blood supply and is characterized by abnormal reactive oxygen species (ROS) production and cell apoptosis. Previous studies have revealed a key role for basic helix-loop-helix family member e40 (Bhlhe40) in oxidative stress and cell apoptosis. This study aimed to investigate the roles of miR-494-3p in cerebral ischemia/reperfusion (I/R) injury. MATERIALS AND METHODS A mouse middle cerebral artery occlusion (MCAO/R) model was established to mimic cerebral ischemia in vivo. Brain infarct area was assessed using triphenyl tetrazolium chloride staining. Oxygen-glucose deprivation/reoxygenation (OGD/R) operation was adopted to mimic neuronal injury in vitro. Cell apoptosis was analyzed by flow cytometry. The relationship between miR-494-3p and Bhlhe40 was validated by luciferase reporter and RNA immunoprecipitation assays. RESULTS Bhlhe40 expression was downregulated both in MCAO/R animal models and OGD/R-induced SH-SY5Y cells. Bhlhe40 overexpression inhibited cell apoptosis and reduced ROS production in SH-SY5Y cells after OGD/R treatment. MiR-494-3p was verified to bind to Bhlhe40 and negatively regulate Bhlhe40 expression. Additionally, cell apoptosis and ROS production in OGD/R-treated SH-SY5Y cells were accelerated by miR-494-3p overexpression. Rescue experiments suggested that Bhlhe40 could reverse the effects of miR-494-3p overexpression on ROS production and cell apoptosis. CONCLUSION MiR-494-3p exacerbates brain injury and neuronal injury by regulating Bhlhe40 after I/R.

Abstract
Neuroinflammation underlies the pathophysiology of multiple age-related neurological disorders. Microglia, the resident immune cells of the central nervous system, are critically involved in neuroinflammatory regulation and neural survival. Modulating microglial activation is thus a promising approach to alleviate neuronal injury. Our serial studies have revealed a neuroprotective role of the δ-opioid receptor (DOR) in several acute and chronic cerebral injuries by regulating neuroinflammation and cellular oxidative stress. More recently, we found an endogenous mechanism for the inhibition of neuroinflammation is closely related to DOR's modulation of microglia. Our recent studies showed that DOR activation could strongly protect neurons from hypoxia- and lipopolysaccharide (LPS)-induced injury by inhibiting microglial pro-inflammatory transformation, while knocking-down DOR or restraining DOR activity promoted microglia activation and the relevant inflammatory events with an aggravation of cell injury. This novel finding highlights a therapeutic potential of DOR in numerous age-related neurological disorders through the modulation of neuroinflammation by targeting microglia. This review summarized the current data regarding the role of microglia in neuroinflammation, oxidative stress, and age-related neurological diseases focusing on the pharmacological effects and signaling transduction of DOR in microglia.

Abstract
Protein- or peptide-based therapeutics have emerged as an innovative strategy for the treatment of cancer. Our previous research demonstrated that tripartite motif 9 short isoform (TRIM9s) is a tumor suppressor in glioma. In this report, we investigated whether a new peptide derived from TRIM9s, named T9sP, inhibits glioma progression and determined the possible molecular mechanism. The CCK-8 proliferation assay was performed in LN229 and U251 glioma cells. The scratch-wound assay was used to determine the migration of the cells. Apoptosis was assessed by flow cytometry using Annexin V-FITC/PI double staining method. The relative protein expression levels were detected by immunoblot analysis. The cell-penetrating peptide TAT was fused with T9sP to form TAT-T9sP. TAT-T9sP efficiently penetrated through the cell membrane of both LN229 and U251 cells. TAT-T9sP inhibited proliferation and migration and promoted apoptosis of glioma cells. TAT-T9sP activated p38 signaling by upregulating MKK6, and a p38 inhibitor, SB203580, reversed the inhibitory effects of TAT-T9sP on glioma cells. These results indicated the potential of TAT-T9sP for the development of a new anti-glioma medicine.

Abstract
BACKGROUND As one of the most common chronic diseases in the world, osteoporosis occurs especially in postmenopausal women. Circular RNAs (circRNAs) are emerging as major drivers in human disease. The aim of the present study was to analyse circRNA expression profiles in osteoporosis and to explore the clinical significance and the regulatory molecular mechanism of hsa_circ_0006859 during osteoporosis. METHODS Exosomes were isolated from clinically collected serum samples. A circRNA microarray was performed to screen differentially expressed circRNAs. Quantitative real-time PCR (qRT-PCR) and western blot were performed to analyse target gene mRNA expression and protein expression. Alizarin red staining (ARS) was performed to evaluate the mineralization ability of human bone marrow mesenchymal stem cells (hBMSCs). Oil Red O staining was performed to evaluate the lipid droplet formation ability of hBMSCs. Bioinformatics analysis and the luciferase reporter assay were performed to investigate the interaction between two genes. RESULTS Hsa_circ_0006859 was identified as one of the most upregulated circRNAs in the microarray analysis. Hsa_circ_0006859 in exosomes was upregulated in osteoporosis patients compared to healthy controls. Hsa_circ_0006859 differentiated osteopenia or osteoporosis patients from healthy controls with high sensitivity and specificity. Hsa_circ_0006859 suppressed osteoblastic differentiation and promoted adipogenic differentiation of hBMSCs. Hsa_circ_0006859 directly bound to miR-431-5p, and ROCK1 was identified as a novel target gene of miR-431-5p. Hsa_circ_0006859 is a competing endogenous RNA (ceRNA) of miR-431-5p that promotes ROCK1 expression. Hsa_circ_0006859 suppressed osteogenesis and promoted adipogenesis by sponging miR-431-5p to upregulate ROCK1. CONCLUSIONS Exosomal hsa_circ_0006859 is a potential biomarker for postmenopausal osteoporosis and controls the balance between osteogenesis and adipogenesis in hBMSCs by sponging miR-431-5p.

Abstract
Our previous studies have shown that the δ-opioid receptor (DOR) is an important neuroprotector via the regulation of PTEN-induced kinase 1 (PINK1), a mitochondria-related molecule, under hypoxic and MPP+ insults. Since mitochondrial dysfunctions are observed in both hypoxia and MPP+ insults, this study further investigated whether DOR is cytoprotective against these insults by targeting mitochondria. Through comparing DOR-induced responses to hypoxia versus MPP+-induced parkinsonian insult in PC12 cells, we found that both hypoxia and MPP+ caused a collapse of mitochondrial membrane potential and severe mitochondrial dysfunction. In sharp contrast to its inappreciable effect on mitochondria in hypoxic conditions, DOR activation with UFP-512, a specific agonist, significantly attenuated the MPP+-induced mitochondrial injury. Mechanistically, DOR activation effectively upregulated PINK1 expression and promoted Parkin's mitochondrial translocation and modification, thus enhancing the PINK1-Parkin mediated mitophagy. Either PINK1 knockdown or DOR knockdown largely interfered with the DOR-mediated mitoprotection in MPP+ conditions. Moreover, there was a major difference between hypoxia versus MPP+ in terms of the regulation of mitophagy with hypoxia-induced mitophagy being independent from DOR-PINK1 signaling. Taken together, our novel data suggest that DOR activation is neuroprotective against parkinsonian injury by specifically promoting mitophagy in a PINK1-dependent pathway and thus attenuating mitochondrial damage.

Abstract
Alzheimer’s disease (AD) is characterized by amyloid plaques and neurofibrillary tangles. Substantial evidence for AD pathogenesis suggests that β-site APP cleaving enzyme 1 (BACE1) and γ-secretase enzyme initiate the amyloidogenic pathway and produces toxic Aβ peptides that prone to aggregate in the brain. Therefore, the inhibition of BACE1 expression and function is an attractive strategy for AD therapy. In the present work, we made the first finding that activating δ-opioid receptors (DOR) with a specific DOR agonist significantly attenuated BACE1 expression and activity in the highly differentiated PC12 cells with mimicked AD injury, while the application of DOR inhibitor naltrindole reversed the UFP-512 effects, and even caused a major increase in BACE1 expression and activity as well as Aβ42 production in physiological conditions. Knocking-down DOR also enhanced BACE1 protein expression and its activity for APP processing, associating with a significant increase in Aβ42 production. In sharp contrast, activation of μ-opioid receptor (MOR) with DAMGO greatly promoted BACE1 expression and activity with an acceleration of APP cleavage, thus contributing to increased Aβ42 production. DADLE, a less selective DOR agonist that may bind to MOR, had no stable inhibitory effect on BACE1. Similar results were also found in APP mutant (APPswe) SH-SY5Y cell line, providing further validation of the DOR action on BACE1 regulation. Our novel data demonstrated entirely different roles of DOR and MOR in the regulation of BACE1 expression and activity with DOR being neuroprotective against AD injury. These findings provided a novel clue for new strategies of AD therapy via targeting endogenous opioid receptors.

Abstract
BACKGROUND Ischaemic stroke is a lethal cerebrovascular disease that occurs worldwide. Astilbin is a natural flavonoid compound with various physiological activities. The purpose of this study was to investigate the neuroprotective effects of Astilbin after cerebral ischaemia reperfusion (I/R) injury. METHODS The oxygen and glucose deprivation (OGD) model was used to simulate cerebral I/R injury in vitro. Cell viability was measured via CCK-8 and LDH release assays. Cell apoptosis was measured via Hoechst 33258 staining and flow cytometry assays. ROS was detected via flow cytometry assay. The protein expression levels were determined by western blotting. The middle cerebral artery occlusion (MCAO) model was used to simulate cerebral I/R injury in vivo. Cerebral ischaemic volume was measured by TTC staining. The Zea-Longa score, rota-rod test, and foot-fault test were used to evaluate behavioural changes and neurological deficits in rats. RESULTS Astilbin significantly enhanced cell viability and decreased LDH release after OGD treatment in vitro. Astilbin effectively curbed cell apoptosis induced by OGD via inhibiting the activation of caspase-3, decreasing the ratio of Bax/Bcl-2 and decreasing FADD. Astilbin also inhibited OGD-induced inflammation by suppressing ROS-NLRP3 inflammasome axis activation. Further results revealed that Astilbin could suppress the MAPK pathway and activate the PI3K/AKT pathway. Finally, Astilbin significantly reduced the cerebral infarction volume and relieved neurological deficits in rats in vivo. CONCLUSION Astilbin could defend against cerebral I/R injury by inhibiting apoptosis and inflammation via suppressing the MAPK pathway and activating the AKT pathway.

Abstract
OBJECTIVE To explore the effects of interventional therapy on human immunodeficiency virus (HIV)-1 Tat interactive protein 2/Tat interactive protein 30 (HTATIP2/TIP30), B7-H4 and short-term curative effect in primary hepatocellular carcinoma. PATIENTS AND METHODS 62 patients with primary hepatocellular carcinoma admitted in our hospital from June 2015 to June 2016 were enrolled in this study and divided into observation group (n = 31) and control group (n = 31) according to the random number table. The patients in the control group were treated with radiofrequency ablation, and the patients in the observation group were treated with transcatheter arterial chemoembolization (TACE). The patients in both groups received liver protection therapy, hydration, antiemetic and stomach protection. The curative effects, the serum HTATIP2/TIP30, B7-H4, alanine aminotransferase (ALT) and total bilirubin in serum (TBIL), life quality before and after treatment, and survival during the 1-year follow-up, were compared. RESULTS The total short-term effective rate (70.97%) was higher than the control group (38.71%) (p < 0.05). The serum levels of HTATIP2/TIP30 and B7-H4 were decreased after treatment in both groups (observation group: t = 17.1838, 18.9795, control group: t = 8.3787, 10.6393, p < 0.05). The serum levels of HTATIP2/TIP30 and B7-H4 after treatment in the observation group were lower than the control group (t = 12.2975, 10.5361, p < 0.05). The levels of ALT and TBIL were decreased after treatment (observation group: t = 15.1716, 34.5771, control group: t = 8.3374, 17.3015, p < 0.05). The levels of ALT and TBIL were lower in the observation groups than the control group (t = 15.2697, 16.8592, p < 0.05). The improvement rate of life quality in the observation group (80.65%) was higher than the control group (54.84%) (p < 0.05). The survival rates of the two groups after 1-year follow-up were not statistically different (p > 0.05). CONCLUSIONS The short-term curative effect of interventional therapy of primary hepatocellular carcinoma is good. It can decrease serum HTATIP2/TIP30 and B7-H4, improves the liver function and the life quality of patients, prolonging the survival time. It has a high research value and it is worthy of further application.

Abstract
OBJECTIVE The aim of this study was to explore whether miR-128 could promote the apoptosis of glioma cells by targeting NIMA related kinase-2 (NEK2), thus participating in the occurrence and progression of glioma. PATIENTS AND METHODS Expression levels of miR-128 and NEK2 in glioma tissues and normal brain tissues were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The relationship between miR-128 expression, tumor size and stage of glioma was analyzed. The effect of miR-128 on the apoptosis of glioma cells was detected by flow cytometry and Western blot, respectively. Dual-luciferase reporter gene assay was applied to verify the binding condition of miR-128 and NEK2. Meanwhile, rescue experiments were conducted to determine whether miR-128 could promote the apoptosis of glioma cells by targeting NEK2. RESULTS The expression level of miR-128 in glioma tissues was significantly lower than that of normal brain tissues. However, NEK2 was highly expressed in glioma tissues. MiR-128 expression was correlated to tumor size and malignant level of glioma, whereas not related to age and gender of glioma patients. Meanwhile, overexpression of miR-128 promoted the apoptosis of U87 cells, upregulated protein levels of cleaved Caspase-3 and BCL2-associated X (Bax), and downregulated B-cell lymphoma-2 (Bcl-2). Dual-luciferase reporter gene assay indicated that miR-128 directly bound to NEK2. Further rescue experiments suggested that NEK2 overexpression partially reversed the effect of miR-128 on the apoptosis of glioma cells. CONCLUSIONS Downregulated miR-128 inhibited the apoptosis of glioma cells via targeting NEK2.

Abstract
Background Glioma is the most common central nervous system (CNS) tumour. p62, an important autophagy adaptor, plays a crucial role in cancer. However, the role of p62 in the progression of glioma is poorly characterized. Methods We examined the expression of p62 in glioma tissues and cell lines. Then we investigated the function of p62 in vitro, and clarified the mechanism underlying the regulation of p62 expression. Results We revealed that p62 was upregulated at both the mRNA and protein levels in human glioma tissues irrelevant to isocitrate dehydrogenase (IDH) status. Then, we found that overexpression of p62 promoted glioma progression by promoting proliferation, migration, glycolysis, temozolomide (TMZ) resistance and nuclear factor κB (NF-κB) signalling pathway, and repressing autophagic flux and reactive oxygen species (ROS) in vitro. In accordance with p62 overexpression, knockdown of p62 exerted anti-tumour effects in glioma cells. Subsequently, we demonstrated that miR-124-3p directly targeted the 3′-UTR of p62 mRNA, leading to the downregulation of p62. Finally, we found that p62 function could be partially reversed by miR-124-3p overexpression. Conclusions Our results demonstrate that p62 can be targeted by miR-124-3p and acts as an oncogene in glioma, suggesting the potential value of p62 as a novel therapeutic target for glioma.

Abstract
NF-κB signaling controls a large set of physiological processes ranging from inflammatory responses to cell death. Its activation is tightly regulated through controlling the activity and stability of multiple signaling components. Here, we identify that NF-κB activation is suppressed by an F-box protein, S-phase kinase associated protein 2 (SKP2). SKP2 deficiency enhanced NF-κB activation as well as the production of inflammatory cytokines. In addition, SKP2 potently blocked the NF-κB activation at the IκB kinase (IKK) level. Mechanistic study further revealed that SKP2 functions as an adaptor to promote an interaction between active IKKβ and the autophagic cargo receptor p62 to mediate IKKβ degradation via selective autophagy. These findings identify a previously unrecognized role of SKP2 in NF-κB activation by which SKP2 acts as a secondary receptor to assist IKKβ delivery to autophagosomes for degradation in a p62-dependent manner.

Abstract
The N6-methyladenosine (m6A) modification influences various mRNA metabolic events and tumorigenesis, however, its functions in nonsense-mediated mRNA decay (NMD) and whether NMD detects induced carcinogenesis pathways remain undefined. Here, we showed that the m6A methyltransferase METTL3 sustained its oncogenic role by modulating NMD of splicing factors and alternative splicing isoform switches in glioblastoma (GBM). Methylated RNA immunoprecipitation-seq (MeRIP-seq) analyses showed that m6A modification peaks were enriched at metabolic pathway-related transcripts in glioma stem cells (GSC) compared with neural progenitor cells. In addition, the clinical aggressiveness of malignant gliomas was associated with elevated expression of METTL3. Furthermore, silencing METTL3 or overexpressing dominant-negative mutant METTL3 suppressed the growth and self-renewal of GSCs. Integrated transcriptome and MeRIP-seq analyses revealed that downregulating the expression of METTL3 decreased m6A modification levels of serine- and arginine-rich splicing factors (SRSF), which led to YTHDC1-dependent NMD of SRSF transcripts and decreased SRSF protein expression. Reduced expression of SRSFs led to larger changes in alternative splicing isoform switches. Importantly, the phenotypes mediated by METTL3 deficiency could be rescued by downregulating BCL-X or NCOR2 isoforms. Overall, these results establish a novel function of m6A in modulating NMD and uncover the mechanism by which METTL3 promotes GBM tumor growth and progression. SIGNIFICANCE: These findings establish the oncogenic role of m6A writer METTL3 in glioblastoma stem cells.

Abstract
p38 signaling is broadly involved in controlling inflammation and stress-induced cell death; however, the mechanisms controlling its activity have seldom been studied. Here, we report that TRIM9 short isoform (TRIM9s) potentiates p38 signaling by stabilizing MKK6. Mechanistic studies revealed that TRIM9s promotes the K63-linked ubiquitination of MKK6 at Lys82, thus inhibiting the degradative K48-linked ubiquitination of MKK6 at the same lysine. MKK6 could also stabilize TRIM9s by promoting the phosphorylation of TRIM9s at Ser76/80 via p38, thereby blocking the ubiquitin-proteasome pathway. Further functional analyses showed that p38 signaling plays a critical role in suppressing glioblastoma progression. Co-reduction of MKK6 and TRIM9s is significantly associated with overall poor survival of glioblastoma patients. We identify a positive feedback loop in p38 signaling generated by MKK6-TRIM9s, which suppresses glioblastoma progression, and we provide insights into the mechanisms by which TRIM9s and MKK6 potentiate p38 signaling through mutual stabilization.

Abstract
Purpose Glioma is a malignant tumor that originates in the brain and spine and is difficult to be completely removed. Though glioma patients receive active treatment, the survival rate is still poor. Therefore, it is urgent to discover a new medicine to treat glioma patients in order to improve the survival rate. In this study, we explored the anticancer effect and the potential mechanism of luteolin on glioma in vitro. Materials and methods Cell viability was determined by Cell Counting Kit-8 (CCK-8) assay. Fluorescent microscopy and flow cytometry analysis were used to determine the cellular apoptosis. Western blot analysis was performed to explore the changes in protein expression. Quantitative reverse transcription-PCR (qRT-PCR) analysis was utilized to evaluate the expression level of the tumor suppressor miR-124-3p. Results CCK-8 assays indicated that luteolin significantly inhibited glioma cell proliferation in a time- and dose-dependent manner. Fluorescent microscopy and flow cytometry analysis confirmed that luteolin induced glioma cell apoptosis. Western blot analysis showed that luteolin induced cellular apoptosis in glioma cells via MAPK activation (JNK, ERK, and p38). Luteolin stimulated the death receptor (FADD) to regulate the apoptosis proteins (Caspase-8, Caspase-3, and PARP). Luteolin increased the expression levels of LC3B II/I and downregulated the level of p62 that promotes cell autophagy. Finally, qRT-PCR confirmed that luteolin upregulated the expression levels of miR-124-3p. Conclusion These findings illustrate that luteolin may be a potential drug for glioma treatment.

Abstract
Glioma is the most common type of primary malignant brain tumor in adults. Our previous work discovered that plasma miR-454-3p may have some advantages in glioma prognosis, but the clinical significance and the regulatory mechanism of miR-454-3p in glioma have not been systematically investigated, especially regarding the relationship between circulating and tissue miR-454-3p. The expression level of miR-454-3p in glioma serum and tissues was analyzed through quantitative real-time PCR (qRT-PCR). Cell-Counting Kit 8 (CCK-8), wound healing, transwell invasion, apoptosis, and immunofluorescence assays were used to assess the role of miR-454-3p in glioma cancer cells. ATG12 was selected as the target gene of miR-454-3p by bioinformatic analysis. The relationship between ATG12 and miR-454-3p was further validated by luciferase reporter assays and Western blot analysis. miR-454-3p was significantly downregulated in tumor tissues, while it was remarkably upregulated in exosomes from the same patients with glioma. The area under curve (AUC) of exosomal miR-454-3p for glioma diagnosis was 0.8663. The exosomal miR-454-3p was prominently lower in the postoperative serums than that in the preoperative serums. High miR-454-3p expression in exosomes or low miR-454-3p expression in tissue was associated with poor prognosis. Restored expression of miR-454-3p suppressed cell proliferation, migration, invasion, and autophagy in glioma. ATG12 was validated as a direct target of miR-454-3p. The overexpression of ATG12 could partially reverse the effects induced by miR-454-3p suppression. Our data indicate that miR-454-3p may serve as an exosomal biomarker and may be developed into a novel treatment for glioma.

Abstract
The delta-opioid receptor (DOR) is one of three classic opioid receptors in the opioid system. It was traditionally thought to be primarily involved in modulating the transmission of messages along pain signaling pathway. Although there were scattered studies on its other neural functions, inconsistent results and contradicting conclusions were found in past literatures, especially in terms of DOR’s role in a hypoxic/ischemic brain. Taking inspiration from the finding that the turtle brain exhibits a higher DOR density and greater tolerance to hypoxic/ischemic insult than the mammalian brain, we clarified DOR’s specific role in the brain against hypoxic/ischemic injury and reconciled previous controversies in this aspect. Our serial studies have strongly demonstrated that DOR is a unique neuroprotector against hypoxic/ischemic injury in the brain, which has been well confirmed in current research. Moreover, mechanistic studies have shown that during acute phases of hypoxic/ischemic stress, DOR protects the neurons mainly by the stabilization of ionic homeostasis, inhibition of excitatory transmitter release, and attenuation of disrupted neuronal transmission. During prolonged hypoxia/ischemia, however, DOR neuroprotection involves a variety of signaling pathways. More recently, our data suggest that DOR may display its neuroprotective role via the BDNF-TrkB pathway. This review concisely summarizes the progress in this field.

Abstract
There is emerging evidence suggesting that neurotoxic insults and hypoxic/ischemic injury are underlying causes of Parkinson's disease (PD). Since PTEN-induced kinase 1 (PINK1) dysfunction is involved in the molecular genesis of PD and since our recent studies have demonstrated that the δ-opioid receptor (DOR) induced neuroprotection against hypoxic and 1-methyl-4-phenyl-pyridimium (MPP+) insults, we sought to explore whether DOR protects neuronal cells from hypoxic and/or MPP+ injury via the regulation of PINK1-related pathways. Using highly differentiated rat PC12 cells exposed to either severe hypoxia (0.5-1% O2) for 24-48 h or varying concentrations of MPP+, we found that both hypoxic and MPP+ stress reduced the level of PINK1 expression, while incubation with the specific DOR agonist UFP-512 reversed this reduction and protected the cells from hypoxia and/or MPP+-induced injury. However, the DOR-mediated cytoprotection largely disappeared after knocking down PINK1 by PINK1 small interfering RNA. Moreover, we examined several important signaling molecules related to cell survival and apoptosis and found that DOR activation attenuated the hypoxic and/or MPP+-induced reduction in phosphorylated Akt and inhibited the activation of cleaved caspase-3, whereas PINK1 knockdown largely deprived the cell of the DOR-induced effects. Our novel data suggests a unique mechanism underlying DOR-mediated cytoprotection against hypoxic and MPP+ stress via a PINK1-mediated regulation of signaling.

Abstract
Background Glioblastoma multiforme (GBM) is the most malignant primary tumor of the central nervous system and is associated with a very poor prognosis. No further improvements in outcomes have been reported since radiotherapy-temozolomide therapy was introduced. Therefore, developing new agents to treat GBM is important. Aim This study aimed to evaluate the anti-tumor effect of evodiamine (Evo) on GBM cells, and to determine the underlying mechanisms involved. Results According to MTT assay results, Evo significantly inhibited the cell proliferation in a time- and dose-dependent manner. Fluorescence microscopy and flow cytometry analyses revealed that Evo induced cell apoptosis in a concentration-dependent manner. Moreover, Evo induced reactive oxygen species (ROS) production and mitochondrial membrane potential (MMP) disruption. Finally, Evo induced apoptosis in cancer cells by suppressing PI3K/AKT signaling and inducing MAPK phosphorylation (p38 and JNK, but not ERK) to regulate apoptotic proteins (Bax, Bcl-2, Cytochrome c, Caspase-3, and PARP). Conclusion In summary, Evo inhibits cell proliferation by inducing cellular apoptosis via suppressing PI3K/AKT and activating MAPK in GBM; these results indicate that Evo may be regarded as a new approach for GBM treatment.

Abstract
Malignant glioma is one of the most common types of primary brain tumours. Long non-coding RNAs (lncRNAs) have recently emerged as a new class of therapeutic targets for many cancers. In this study, we aimed to explore the functional involvement of small nucleolar RNA host gene 14 (SNHG14) and its potential regulatory mechanism in glioma progression. SNHG14 was found to be downregulated in human glioma tissues and cell lines. SNHG14 significantly inhibited cell viability, reduced cell invasion, and induced apoptosis in glioma cell lines. Furthermore, a correlation analysis demonstrated that there was a negative correlation between SNHG14 expression and miR-92a-3p expression. Bioinformatics prediction and luciferase reporter assays demonstrated that miR-92a-3p could directly bind to SNHG14. miR-92a-3p was significantly upregulated in glioma and acted as an oncogene in glioma cells by inhibiting Bim. Moreover, mechanistic investigations showed that miR-92a-3p could reverse the tumour suppressive effects induced by SNHG14 in glioma, indicating that SNHG14 may act as an endogenous sponge that competes for binding to miR-92a-3p. Our results suggest that SNHG14 and miR-92a-3p may be promising molecular targets for glioma therapy.

Abstract
BACKGROUND/AIMS Hypoxic/ischemic injury to the liver is a frequently encountered clinical problem with limited therapeutic options. Since microRNAs (miRNAs) are involved in hypoxic/ ischemic events, and δ-opioid receptor (DOR) is protective against hypoxic/ischemic injury, we asked if pharmacological activation of DOR can alter hypoxic events by regulating miRNA expression in the liver. As the first step, the present work aimed at testing the effect of DOR activation on hepatic miRNA expression in hypoxia. METHODS Male Sprague Dawley rats were exposed to hypoxia (9.5-10% O2) for 1, 5, or 10 days with or without DOR activation. The target miRNAs were selected according to TaqMan low-density array (TLDA) data and analyzed by quantitative real-time PCR. RESULTS We found that: 1) 1-day hypoxia caused the upregulation of 9 miRNAs (miR-7a-5p, miR-10a-5p, miR-25-3p, miR-26b-5p, miR-122-5p, miR-128a-3p, miR-135b-5p, miR-145-5p, and miR-181a-5p) and the downregulation of 2 miRNAs (miR-34a-5p and miR-182); 2) 5 and 10-days hypoxia altered the expression of 4 miRNAs (miR-34c-5p, miR-184, miR-107-3p and miR192-5p); 3) DOR activation shifted the expression of 8 miRNAs (miR-122-5p, miR-146a-5p, miR-30e-5p, miR-128a-3p, miR-182, miR-192-5p miR-107-3p and miR-184) in normoxic condition; and 4) DOR activation modified hypoxia-induced changes in 6 miRNAs (miR-142-5p, miR-145-5p, miR-146a-5p, miR-204-5p, miR-34a-5p and miR-192-5p). CONCLUSION Hypoxia significantly modifies the miRNA profile in the liver, while DOR activation can modify the hypoxic modification. Therefore, it is potentially possible to alter hypoxic/ischemic pathophysiology in the liver through DOR pharmacotherapy.

Abstract
Crohn's disease and ulcerative colitis are inflammatory bowel diseases (IBDs) with high prevalence in humans. Carnosic acid (CA) has been reported to possess antioxidative properties; however, its role in IBDs has not been determined. In the present study, we found that CA significantly prevented the loss of body weight and shortening of colon length in acute colitis induced by dextran sodium sulfate (DSS). Pronounced infiltration of immune cells and a loss of crypt architecture and goblet cells were ameliorated by CA. CA significantly decreased the activity of MPO and infiltration of F4/80+ macrophages in the colon. DSS-induced pro-inflammatory cytokine mRNA and protein levels in the colon were also attenuated by CA. CA decreased the activation of p65 and c-Jun signalling. CA inhibited DSS-induced NLRP3 inflammasome activation by reducing caspase 1 activity. In addition, CA increased the level of Nrf2 and prevented the degradation of Nrf2 via ubiquitination by blocking the interaction between Cullin3 and Keap1, which resulted in the decrease of Nrf2 target genes. Finally, GSH levels and SOD activity were increased after CA treatment, while MDA and iNOS levels were significantly reduced. Taken together, our data showed that CA may be useful as a potential therapeutic candidate for IBDs.

Abstract
BACKGROUND Recently, favorable outcomes from several randomized controlled trials of rapid endovascular treatment for acute ischemic stroke has emerged. OBJECTIVE The aim of this retrospective study is to present our clinical experience in severe acute vertebrobasilar occlusion (AVBO) using intra-arterial treatment (IAT). METHODS Twenty patients with ischemic stroke in the vertebrobasilar circulation treated by IAT between March 2011 and December 2014 were included. We retrospectively assessed National Institutes of Health Stroke Scale (NIHSS) score on admission and at discharge, Thrombolysis in Cerebral Infarction (TICI) scale, and clinical outcome using modified Rankin scale (mRs) at 90 days, and causes of stroke were prospectively assessed. RESULTS The mean NIHSS score on admission was 26.4 ± 7.9 (range 9-33) points. The mean time from symptom onset to revascularization was 349.5 ± 124.0 (range 201-579) minutes. Successful recanalization (TICI ≥2b) was achieved in 19 (95.0%) patients. The mean NIHSS score at discharge was 5.7 ± 9.0 (range 0-30) points. A favorable clinical outcome (mRS ≤2) was observed in 12 (60.0%) patients at 90 days and mortality was 25.0% (n = 5). CONCLUSION IAT for AVBO provides high rate of recanalization, favorable clinical outcome, and improved survival.

Abstract
Long non-coding RNAs (lncRNAs), which are non-coding RNAs with a length above 200 nucleotides, have emerged as novel and important gene expression modulators in carcinogenesis. Recent evidence indicates that the lncRNA small nucleolar RNA host gene 1 (SNHG1) functions as an oncogene in several types of human cancers. However, its function in the development of glioma remains unknown. The aim of this research was to investigate the clinical aspects and biological mechanisms of SNHG1 in glioma. SNHG1 expression was measured in glioma tissues and cell lines by quantitative real-time PCR (qRT-PCR). The association between SNHG1 expression in tissues and clinicopathological characteristics and prognosis in glioma patients was also explored. Gain-of-function and loss-of-function studies using SNHG1 cDNA and siRNA, respectively, were used to investigate the role of SNHG1 in cell proliferation, invasion and apoptosis in glioma. SNHG1 was highly expressed in glioma tissues, and its upregulation was closely related to old age. Kaplan-Meier analysis showed that high expression of SNHG1 was significantly associated with poor overall survival (OS). Functionally, ectopic expression of SNHG1 enhanced cell proliferation and cell invasion and reduced cell apoptosis in vitro, while SNHG1 knockdown reversed these effects. Taken together, our findings indicate that SNHG1 functions as an oncogene in glioma and may serve as a novel therapeutic target in future treatments.

Abstract
Programmed cell death 4 (PDCD4) is a RNA-binding protein that acts as a tumor suppressor in many cancer types, including colorectal cancer (CRC). During CRC carcinogenesis, PDCD4 protein levels remarkably decrease, but the underlying molecular mechanism for decreased PDCD4 expression is not fully understood. In this study, we performed bioinformatics analysis to identify miRNAs that potentially target PDCD4. We demonstrated miR-181b as a direct regulator of PDCD4. We further showed that activation of IL6/STAT3 signaling pathway increased miR-181b expression and consequently resulted in downregulation of PDCD4 in CRC cells. In addition, we investigated the biological effects of PDCD4 inhibition by miR-181b both in vitro and in vivo and found that miR-181b could promote cell proliferation and migration and suppress apoptosis in CRC cells and accelerate tumor growth in xenograft mice, potentially through targeting PDCD4. Taken together, this study highlights an oncomiR role for miR-181b in regulating PDCD4 in CRC and suggests that miR-181b may be a novel molecular therapeutic target for CRC.

Abstract
BACKGROUND Hypoxic/ischemic injury to the heart is a frequently encountered clinical problem with limited therapeutic options. Since microRNAs (miRNAs) are involved in hypoxic/ischemic events, and δ-opioid receptor (DOR) activation is known to protect against hypoxic/ischemic injury, we speculated on the involvement of DOR activation in altering miRNA expression in the heart under hypoxic conditions. The present study aimed to test our hypothesis. METHODS Male Sprague Dawley rats were exposed to hypoxia (9.5-10% O2) for 1, 5, or 10 days with or without DOR activation. The target miRNAs were selected from TaqMan low-density array (TLDA) data and were further analyzed by quantitative real-time PCR. RESULTS We found that: 1) hypoxia alters the miRNA expression profiles depending on the hypoxic duration; 2) DOR activation shifts miRNA expression profiles in normoxic conditions and upregulates miR-128a-3p, miR-134-5p, miR-135a, miR-193a-3p, miR-196a, miR-324-3p, and miR-338; and 3) DOR activation modifies hypoxia-induced changes in miRNA expression and increases the levels of miR-128a-3p, miR-134-5p, miR-135a, miR-193a-3p, miR-196a, miR-324-3p, miR-141, miR-200b, and miR-324-3p. For example, miR-196c-5p decreased by 50% while miR-135a-5p increased 2.9 fold after 10 days under hypoxic conditions. Moreover, DOR activation further strengthened the hypoxia-induced increase of the levels of miR-7a-5p. When DOR was activated using UFP-512, the level of miR-107-3p significantly increased 1 day after the administration of UFP-512, but gradually decreased back to normal under normoxia. CONCLUSION Hypoxia significantly modifies the miRNA profile in the heart, which can be mimicked or modified by DOR activation. Defining the targeted pathways that regulate the diverse cellular and molecular functions of miRNAs may provide new insights into potential therapies for hypoxic/ischemic injury of the heart.

Abstract
The pathological changes of Parkinson's disease (PD) are, at least partially, associated with the dysregulation of PTEN-induced putative kinase 1 (PINK1) and caspase 3. Since hypoxic and neurotoxic insults are underlying causes of PD, and since δ-opioid receptor (DOR) is neuroprotective against hypoxic/ischemic insults, we sought to determine whether DOR activation could protect the cells from damage induced by hypoxia and/or MPP⁺ by regulating PINK1 and caspase 3 expressions. We exposed PC12 cells to either severe hypoxia (0.5%-1% O₂) for 24-48 h or to MPP⁺ at different concentrations (0.5, 1, 2 mM) and then detected the levels of PINK1 and cleaved caspase 3. Both hypoxia and MPP⁺ reduced cell viability, progressively suppressed the expression of PINK1 and increased the cleaved caspase 3. DOR activation using UFP-512, effectively protected the cells from hypoxia and/or MPP⁺ induced injury, reversed the reduction in PINK1 protein and significantly attenuated the increase in the cleaved caspase 3. On the other hand, the application of DOR antagonist, naltrindole, greatly decreased cell viability and increased cleaved caspase 3. These findings suggest that DOR is cytoprotective against both hypoxia and MPP⁺ through the regulation of PINK1 and caspase 3 pathways.

Abstract
The PIM1 protein is an important regulator of cell proliferation, the cell cycle, apoptosis, and metabolism in various human cancers. MicroRNAs (miRNAs) are powerful post‐transcriptional gene regulators that function through translational repression or transcript destabilization. Therefore, we aimed to identify whether a close relationship exists between PIM1 and miRNAs. PIM1 protein levels and mRNA levels were significantly upregulated in astrocytoma tissues, indicating the oncogenic role of PIM1 in astrocytoma. Further bioinformatics analysis indicated that miR‐124‐3p targeted the 3′‐UTR of PIM1. We also observed an inverse correlation between the miR‐124‐3p levels and PIM1 protein or mRNA levels in astrocytoma samples. Next, we experimentally confirmed that miR‐124‐3p directly recognizes the 3′‐UTR of the PIM1 transcript and regulates PIM1 expression at both the protein and mRNA levels. Furthermore, we examined the biological consequences of miR‐124‐3p targeting PIM1 in vitro. We showed that the repression of PIM1 in astrocytoma cancer cells by miR‐124‐3p suppressed proliferation, invasion, and aerobic glycolysis and promoted apoptosis. We observed that the restoration or inhibition of PIM1 activity resulted in effects that were similar to those induced by miR‐124‐3p inhibitors or mimics in cancer cells. Finally, overexpression of PIM1 rescued the inhibitory effects of miR‐124‐3p. In summary, these findings aid in understanding the tumor‐suppressive role of miR‐124‐3p in astrocytoma pathogenesis through the inhibition of PIM1 translation.

Abstract
Hypoxia and ischemia play a major role in the pathogenesis of cerebrovascular diseases such as stroke. However, the protective strategies against hypoxic and ischemic insults are very limited in clinical settings. This has reinforced the need to improve our understanding of the hypoxic and ischemic cascades and explore novel solutions of hypoxic/ ischemic injury. Recent research has identified the crucial role of microRNAs in regulation of gene expression under hypoxic/ischemic conditions. These 19-24 ribonucleotide non-coding RNA molecules function as inhibitory modulators of gene expression, by targeting mRNAs and promoting either RNA degradation or translational repression. They are differentially regulated in the brain as well as other organs under hypoxic and ischemic conditions. Targeting microRNA expression/activity offers a potentially effective way to intervene against hypoxic and ischemic injury. In this review, we highlight recent updates with summary of our recent work, which provides an insight into the roles and mechanisms of microRNA-induced regulation of cellular and molecular processes in response to hypoxic and/or ischemic stress.

Abstract
Acetaminophen (APAP) overdose is the most frequent cause of drug-induced acute liver failure. The purpose of this study was to investigate whether paeonol protected against APAP-induced hepatotoxicity. Mice treated with paeonol (25, 50, 100 mg/kg) received 400 mg/kg acetaminophen intraperitoneally (i.p.) and hepatotoxicity was assessed. Pre-treatment with paeonol for 6 and 24 h ameliorated APAP-induced hepatic necrosis and significantly reduced the serum alanine aminotransferase (ALT) and aspartate transaminase (AST) levels in a dose-dependent manner. Post-treatment with 100 mg/kg paeonol ameliorated APAP-induced hepatic necrosis and reduced AST and ALT levels in the serum after APAP administration for 24 h. Western blot revealed that paeonol inhibited APAP-induced phosphorylated JNK protein expression but not p38 and Erk1/2. Moreover, paeonol showed anti-oxidant activities with reducing hepatic MDA contents and increasing hepatic SOD, GSH-PX and GSH levels. Paeonol dose-dependently prevented against H2O2 or APAP-induced LDH releasing and ROS production in primary mouse hepatocytes. In addition, the mRNA levels of pro-inflammatory genes such as TNF-α, MCP-1, IL-1β and IL-6 in the liver were dose-dependently reduced by paeonol pre-treatment. Pre-treatment with paeonol significantly inhibited IKKα/β, IκBα and p65 phosphorylation which contributed to ameliorating APAP-induced hepatic inflammation. Collectively, the present study demonstrates paeonol has a protective ability against APAP-induced hepatotoxicity and might be an effective candidate compound against drug-induced acute liver failure.

Abstract
OBJECTIVE This study was to investigate the expression of miR-10a in the different FAB subtype of acute myeloid leukemia (AML) and its relationship with drug resistance. METHODS Forty de novo patients with AML, 16 patients with non-malignant hematologic disease and three AML cell lines HL-60, U937 and HL-60/ADR were enrolled in this study, the MiR-10a expression in bone marrow mononuclear cells of above-mentioned patients and 3 AML cell lines was detected by TaqMan RT-PCR. The correlation of miR-10a with clinicopathological factors of AML patients was analyzed. RESULTS The miR-10a expression level in HL-60 cell line was higher than that in U937 cell line (P = 0.039). And its expression level in de novo AML patients was higher than that in patients with non-malignant hematologic disease (P < 0.01). FAB-AML-M3 patients exhibited higher expression of miR-10a than that in M1, M2 and M4 (P < 0.05); HL-60/ADR cell line showed higher miR-10a expression than that in HL-60 cell line (P < 0.01) . Except M3, the patients without CR (non-CR) after the first cycle of chemotherapy showed a higher level of miR-10a as compared with CR patients (P < 0.01). CONCLUSION The high expression of miR-10a may be closely related to over-proliferation of promyelocyte and drug resistance of acute myeloid leukemia cells, except M3.

Abstract
Long noncoding RNAs (lncRNAs) are pervasively transcribed and play a key role in tumorigenesis. The aim of the study was to determine the lncRNA expression profile in astrocytomas and to assess its potential clinical value. We performed a three-step analysis to establish the lncRNA profile for astrocytoma: a) the lncRNA expression was examined on 3 astrocytomas as well as 3 NATs (normal adjacent tissues) using the lncRNA microarray; b) the top-hits were validated in 40 astrocytomas (WHO grade II-IV) by quantitative real time-PCR (qRT-PCR); c) the hits with significant differences were re-evaluated using qRT-PCR in 90 astrocytomas. Finally, 7 lncRNAs were found to have a significantly different expression profile in astrocytoma samples compared to the NAT samples. Unsupervised clustering analysis further revealed the potential of the 7-lncRNA profile to differentiate between tumors and NAT samples. The upregulation of ENST00000545440 and NR_002809 was associated with advanced clinical stages of astrocytoma. Using Kaplan-Meier survival analysis, we showed that the low expression of BC002811 or XLOC_010967, or the high expression of NR_002809 was significantly associated with poor patient survival. Moreover, Cox proportional hazard regression analysis revealed that this prognostic impact was independent of other clinicopathological factors. Our results indicate that the lncRNA profile may be a potential prognostic biomarker for the prediction of post-surgical outcomes.

Abstract
Protein-based nanoparticles hold great promises in both preclinical and clinical practices, such as oncology diagnosis and treatment, because of their high biocompatibility and biodegradability. However, the complicated preparation and lack of targeting specific cells or tissues may limit their further uses. To overcome these limitations, we developed a novel replacing method for preparing dual-functional protein nanocarrier, such that one function is capable of encapsulating small molecule into protein, whereas the other function is cable of recognizing CD163 receptor [hemoglobin (Hb) scavenger receptor]. In this study, Hb was chosen as the targeting drug carrier. First, the heme group in the Hb was removed and replaced by paclitaxel (PTX) to form nanoparticles (Gb-NPs-PTX). The resulted Gb-NPs-PTX showed spherical shape and their diameter could be controlled in the range of 120-160 nm by altering the ratio of PTX to Hb. The binding activity of Gb-NPs-PTX to CD163 was confirmed by cell uptake in CD163(+) Chinese hamster ovary cells. Results in vivo also showed a CD163-dependent tissue accumulation of Gb-NPs-PTX in mice. In summary, by using the novel replacing method, PTX could be easily encapsulated into Hb nanoparticles and the targeting effects of Hb could also be kept.

Abstract
Background Tubeimoside-1 (TBMS1) is a natural compound isolated from tubeimoside, which has been widely used as a traditional Chinese herbal medicine. The purpose of the present study is to investigate the anti-tumor effect and the underling mechanism of TBMS1 on glioma cancer cells. Methods The MTT assay was performed to evaluate the effect of TBMS1 on glioma cell proliferation. The fluorescent microscopy and flow cytometry analysis were performed to evaluate the effect of TBMS1 on glioma cell apoptosis. The Western blot analysis was used to evaluate the protein change. Results TBMS1 inhibited glioma cancer cell proliferation in a dose- and time-dependent manner. Fluorescent microscopy and flow cytometry analysis demonstrated that TBMS1 induced glioma cell apoptosis in a concentration-dependent manner. Western blotting showed that TBMS1 induced apoptosis by increasing the expression of Bax and downregulating the level of Bcl-2. Furthermore, we found that TBMS1 induced apoptosis by increasing the concentration of reactive oxygen species through the release of Cytochrome C and activation of Caspase-3. Conclusion These findings indicate that TBMS1 may be developed as a possible therapeutic agent for the management of glioma.

Abstract
BACKGROUND Circulating microRNAs (miRNAs) are emerging as promising biomarkers for human cancer. In the current study, we investigated the potential use of serum miRNAs as biomarkers for diagnosis and prognosis in a cohort of Chinese astrocytoma patients. METHODS An initial screening of the circulating miRNA expression profile was performed on pooled serum samples from 10 preoperative patients and 10 healthy controls using a TaqMan low-density array. The selected serum miRNAs were then validated in 90 preoperative patients and 110 healthy controls who were randomly divided into a training set and a validation set. An additional double-blind test was performed in 50 astrocytomas and 50 controls to assess the serum miRNA-based biomarker accuracy in predicting astrocytoma. The differentially expressed miRNAs were evaluated in paired preoperative and postoperative serum samples from 73 astrocytoma patients. The correlation of the miRNA levels with survival in astrocytoma samples was estimated. RESULTS Nine serum miRNAs were significantly increased in the astrocytoma patients. The biomarker composed of these 9 miRNAs had high sensitivity, specificity, and accuracy. These 9 miRNAs were markedly decreased in the serum after operation. The upregulation of miR-20a-5p, miR-106a-5p, and miR-181b-5p was associated with advanced clinical stages of astrocytoma. Kaplan-Meier survival analysis showed that the high expression of miR-19a-3p, miR-106a-5p, and miR-181b-5p was significantly associated with poor patient survival. Finally, the combined 3-miRNAs panel was an important prognostic predictor, independent of other clinicopathological factors. CONCLUSIONS The results indicated the potential of serum miRNAs as novel diagnostic and prognostic biomarkers for human astrocytoma.

Abstract
Neuroblastoma, a malignant embryonal tumor of the sympathetic nervous system, is the most common solid extracranial malignancy of childhood and accounts for 15 % of all childhood cancer deaths. The biological behavior of neuroblastoma is extensively heterogeneous, ranging from spontaneous regression to rapid progression despite multimodal aggressive therapy. Although the molecular basis of neuroblastoma has received considerable attention over the past decade, elucidating the mechanisms for the aggressive progression of neuroblastoma is needed for improving the efficacy of treatment. miRNAs (microRNAs) are small non-coding RNA molecules generally 19-22 nucleotides in length. miRNAs regulate 60 % of human gene expression at the post-transcriptional level by targeting regions of sequence complementarity on the 3'-untranslated regions (3'-UTRs) of specific mRNAs. miRNAs can either cause degradation of mRNAs or can inhibit their translation and therefore play major roles in normal growth and development. miRNA dysregulation has oncogenic or tumor-suppressive functions in virtually all forms of cancer, including neuroblastoma. The present review highlights the current insights on dysregulated miRNAs in neuroblastoma and on their roles in the diagnosis, prognosis, and treatment of this malignancy. As a rapidly evolving field of basic and biomedical sciences, miRNA research holds a great potential to impact on the management of neuroblastoma.

Abstract
Astrocytomas are common malignant intracranial tumors that comprise the majority of adult primary central nervous system tumors. MicroRNAs (miRNAs) are small, non-coding RNAs (20–24 nucleotides) that post-transcriptionally modulate gene expression by negatively regulating the stability or translational efficiency of their target mRNAs. In our previous studies, we found that the downregulation of miR-106a-5p in astrocytomas is associated with poor prognosis. However, its specific gene target(s) and underlying functional mechanism(s) in astrocytomas remain unclear. In this study, we used mRNA microarray experiments to measure global mRNA expression in the presence of increased or decreased miR-106a-5p levels. We then performed bioinformatics analysis based on multiple target prediction algorithms to obtain candidate target genes that were further validated by computational predictions, western blot analysis, quantitative real-time PCR, and the luciferase reporter assay. Fas-activated serine/threonine kinase (FASTK) was identified as a direct target of miR-106a-5p. In human astrocytomas, miR-106a-5p is downregulated and negatively associated with clinical staging, whereas FASTK is upregulated and positively associated with advanced clinical stages, at both the protein and mRNA levels. Furthermore, Kaplan-Meier analysis revealed that the reduced expression of miR-106a-5p or the increased expression of FASTK is significantly associated with poor survival outcome. These results further supported the finding that FASTK is a direct target gene of miR-106a-5p. Next, we explored the function of miR-106a-5p and FASTK during astrocytoma progression. Through gain-of-function and loss-of-function studies, we demonstrated that miR-106a-5p can significantly inhibit cell proliferation and migration and can promote cell apoptosis in vitro. The knockdown of FASTK induced similar effects on astrocytoma cells as those induced by the overexpression of miR-106a-5p. These observations suggest that miR-106a-5p functions as a tumor suppressor during the development of astrocytomas by targeting FASTK.

Abstract
Delta-opioid receptors (DOR) are involved in cardioprotection under hypoxia/ ischemia. However, the underlying mechanism is not well understood yet. We have recently shown that DOR activation significantly modify the expression of hypoxia-sensitive microRNAs (miRNAs) in the brain and kidney. In extension, we further investigated if DOR activation can regulate cardiac miRNAs in hypoxia. We compared global changes in miRNA gene expression in the rat heart following exposure to hypoxia for 10 days with those in normoxia using a low density miRNA microarray to delineate hypoxia-induced changes in the miRNA expression. The up-regulated miRNAs from the microarray analysis were selected for further investigating their response to hypoxia and DOR activation with a DOR agonist, UFP-512 after 1, 5, and 10 days. We found that 1) miR-376a increased after 1-day hypoxia and progressively increased with hypoxic duration; 2) miR-7b, miR-107, miR-134, miR-135a, miR-193a-3p, miR-196a and miR-324-3p progressively increased after 1-day hypoxia and reached a peak after 5-days; 3) miR-7a, miR-141, miR-196c, miR-200a, miR-200b, miR-203a and miR-324 increased only after 1-day hypoxia and significantly decreased after 5-10 days of hypoxia; 4) miR-128a did not significantly change after 1-10 days of hypoxia. After DOR activation with UFP-512, miR-128a, miR-135a, miR-193a-3p, miR-196a, miR-200a, miR-324-3p and miR-338 continued to increase after 1-day hypoxia, and then decreased after 5-10 days of hypoxia; 5) miR-7b and miR-134, in the condition of DOR activation, increased after 1-day hypoxia and further increased after 5-day hypoxia, while significantly decreased after 10-day exposure. In contrast, some miRNAs like miR-350 decreased in response to hypoxia, while DOR activation almost completely reversed such hypoxic reduction. These results suggest that cardiac miRNAs differentially respond to hypoxic stress with a variable degree directly related to the duration of hypoxic exposure, and DOR activation can regulate such hypoxic responses.

Abstract
Hypoxic/ischemic injury to kidney is a frequently encountered clinical problem with limited therapeutic options. Since microRNAs are differentially involved in hypoxic/ischemic events and δ-opioid receptor (DOR) activation is known to protect against hypoxic/ischemic injury, we speculated on the involvement of DOR activation in altering the microRNA (miRNA) expression in kidney under hypoxic condition. We selected 31 miRNAs based on microarray data for quantitative PCR analysis. Among them, 14 miRNAs were significantly altered after prolonged hypoxia, DOR activation or a combination of both. We found that 1) DOR activation alters miRNA expression profiles in normoxic conditions; 2) hypoxia differentially alters miRNA expression depending on the duration of hypoxia; and 3) DOR activation can modify hypoxia-induced changes in miRNA expression. For example, 10-day hypoxia reduced the level of miR-212 by over 70%, while DOR activation could mimic such reduction even in normoxic kidney. In contrast, the same stress increased miR-29a by >100%, which was reversed following DOR activation. These first data suggest that hypoxia comprehensively modifies the miRNA profile within the kidney, which can be mimicked or modified by DOR activation. Ascertaining the targeted pathways that regulate the diverse cellular and molecular functions of miRNA may provide new insights into potential therapies for hypoxic/ischemic injury of the kidney.

Abstract
Multidrug resistance (MDR) is a major impediment to successful cancer chemotherapy. Co-delivery of novel MDR-reversing agents and anticancer drugs to cancer cells holds great promise for cancer treatment. MicroRNA-21 (miR-21) overexpression is associated with the development and progression of MDR in breast cancer, and it is emerging as a novel and promising MDR-reversing target. In this study, a multifunctional nanocomplex, composed of polyethylenimine (PEI)/poly(sodium 4-styrenesulfonates) (PSS)/graphene oxide (GO) and termed PPG, was prepared using the layer-by-layer assembly method to evaluate the reversal effects of PPG as a carrier for adriamycin (ADR) along with miR-21 targeted siRNA (anti-miR-21) in cancer drug resistance. ADR was firstly loaded onto the PPG surface (PPGADR) by physical mixing and anti-miR-21 was sequentially loaded onto PPGADR through electric absorption to form anti-miR-21PPGADR. Cell experiments showed that PPG significantly enhanced the accumulation of ADR in MCF-7/ADR cells (an ADR resistant breast cancer cell line) and exhibited much higher cytotoxicity than free ADR, suggesting that PPG could effectively reverse ADR resistance of MCF-7/ADR. Furthermore, the enhanced therapeutic efficacy of PPG could be correlated with effective silencing of miR-21 and with increased accumulation of ADR in drug-resistant tumor cells. The endocytosis study confirmed that PPG could effectively carry drug molecules into cells via the caveolae and clathrin-mediated endocytosis pathways. These results suggest that this PPG could be a potential and efficient non-viral vector for reversing MDR, and the strategy of combining anticancer drugs with miRNA therapy to overcome MDR could be an attractive approach in cancer treatment.
