Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhubarb is the peeled and dried roots of Rheum palmatum L. and Rheum tanguticum Maxim. ex Balf. or Rheum officinale Baill. Free total rhubarb anthraquinones (FTRAs) were isolated and extracted from rhubarb. Previous studies have revealed that the early administration of FTRAs protects the intestinal mucosal barrier in rats with severe acute pancreatitis (SAP), the mechanism of which is not yet clear. However, we observed an enhanced expression of intestinal pyroptotic factors in rats treated with SAP, which may be related to the mechanism of intestinal barrier protection by FTRAs. AIM OF THE STUDY The main objective of this study was to investigate the mechanism by which FTRAs protect the intestinal mucosal barrier in SAP rats, focusing on the classical pyroptosis pathway. MATERIALS AND METHODS SAP was induced in rats through retrograde injection of sodium taurocholate via the pancreaticobiliary duct. Subsequently, FTRAs (22.5, 45, and 90 mg/kg), rhubarb (900 mg/kg, positive control), and saline (control) were administered at 0 h (immediately), 12 h, and 24 h post-surgery. Pancreatic and intestinal tissue injury, positive PI staining rate, and expression levels of various factors in intestinal tissues were compared across different groups. These factors include diamine oxidase (DAO), lactate dehydrogenase (LDH), high mobility group box chromosomal protein 1(HMGB1) and pro-inflammatory factors in intestinal and serum, pyroptosis-associated factors, toll-like receptor 4 (TLR-4), nuclear factor kappa-B (NF-kB), apoptosis-associated speck-like protein (ASC), NOD-like receptor protein 3 (NLRP3), cysteine protease-1 (caspase-1) and Gasdermin (GSDMD). RESULTS The findings indicated that FTRAs protected the damaged intestine and pancreas and restored the expression of intestinal epithelial junction proteins in SAP rats. Additionally, it reduced intestinal and serum levels of DAO, interleukin 1, interleukin 18, HMGB1, and LDH, attenuated intestinal Positive PI staining rate, and significantly decreased the expressions of TLR-4, NF-kB, ASC, NLRP3, caspase-1 and GSDMD in SAP rats. CONCLUSIONS The results suggest that FTRAs inhibited pyroptosis through down-regulation of the NLRP3-Caspase-1-GSDMD and TLR-4- NF-kB signaling pathways of intestinal tissues., thereby protecting the intestinal barrier of SAP rats.

Abstract
Poly (ADP-ribose) polymerase 1 (PARP1) is a first responder that recognizes DNA damage and facilitates its repair. Neurodegenerative diseases, characterized by progressive neuron loss driven by various risk factors, including DNA damage, have increasingly shed light on the pivotal involvement of PARP1. During the early phases of neurodegenerative diseases, PARP1 experiences controlled activation to swiftly address mild DNA damage, thereby contributing to maintain brain homeostasis. However, in late stages, exacerbated PARP1 activation precipitated by severe DNA damage exacerbates the disease condition. Consequently, inhibition of PARP1 overactivation emerges as a promising therapeutic approach for neurodegenerative diseases. In this review, we comprehensively synthesize and explore the multifaceted role of PARP1 in neurodegenerative diseases, with a particular emphasis on its over-activation in the aggregation of misfolded proteins, dysfunction of the autophagy-lysosome pathway, mitochondrial dysfunction, neuroinflammation, and blood-brain barrier (BBB) injury. Additionally, we encapsulate the therapeutic applications and limitations intrinsic of PARP1 inhibitors, mainly including limited specificity, intricate pathway dynamics, constrained clinical translation, and the heterogeneity of patient cohorts. We also explore and discuss the potential synergistic implementation of these inhibitors alongside other agents targeting DNA damage cascades within neurodegenerative diseases. Simultaneously, we propose several recommendations for the utilization of PARP1 inhibitors within the realm of neurodegenerative disorders, encompassing factors like the disease-specific roles of PARP1, combinatorial therapeutic strategies, and personalized medical interventions. Lastly, the encompassing review presents a forward-looking perspective along with strategic recommendations that could guide future research endeavors in this field.

Abstract
Myeloid RNA regulator of Bim-induced death (Morrbid) is a newly identified leukocyte-specific long noncoding RNA (lncRNA). However, the expression and biological functions of Morrbid in cardiomyocytes and heart disease are currently unclear. This study was meant to determine the role of cardiac Morrbid in acute myocardial infarction (AMI) and to identify the potential cellular and molecular mechanisms involved. We found that both human and mouse cardiomyocytes could express a significant amount of Morrbid and that its expression was increased in cardiomyocytes with hypoxia or oxidative stress as well as in mouse hearts with AMI. Overexpression of Morrbid reduced the myocardial infarct size and cardiac dysfunction, whereas the infarct size and cardiac dysfunction deteriorated in cardiomyocyte-specific Morrbid-KO (Morrbidfl/fl/Myh6-Cre) mice. We identified that Morrbid had a protective effect against hypoxia- or H2O2-induced apoptosis; this was also confirmed in vivo in mouse hearts after AMI. We further discovered that serpine1 was a direct target gene of Morrbid that was involved in the Morrbid-mediated protective effect on cardiomyocytes. In summary, we have found, for the first time to our knowledge, that the cardiac Morrbid is a stress-enhanced lncRNA that protects hearts from AMI via antiapoptosis through its target gene serpine1. Morrbid may be a novel promising therapeutic target for ischemic heart diseases such as AMI.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder in women of reproductive age that still lacks effective treatment. Inflammation is one of the important features of PCOS. Asparagus (ASP) has anti-inflammatory, antioxidant, and anti-aging pharmacological effects, and its anti-tumor effects have been demonstrated in a variety of tumors. However, the role and mechanism of ASP in PCOS remain unclear. METHODS The active components of ASP and the key therapeutic targets for PCOS were obtained by network pharmacology. Molecular docking was used to simulate the binding of PRKCA to the active components of ASP. The effects of ASP on inflammatory and oxidative stress pathways in PCOS, and the regulation of PRKCA were examined by KGN, a human derived granulosa cell line. PCOS mouse model validated the results of in vivo experiments. RESULTS Network pharmacology identified 9 major active ingredients of ASP with 73 therapeutic targets for PCOS. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment yielded 101 PCOS-related signaling pathways. The hub gene PRKCA was obtained after taking the gene intersection of the top 4 pathways. Molecular docking showed the binding of PRKCA to the 7 active components in ASP. In vitro and in vivo experiments showed that ASP alleviated the course of PCOS through antioxidant, anti-inflammatory effects. ASP can partially restore the low expression of PRKCA in the PCOS models. CONCLUSION The therapeutic effect of ASP on PCOS is mainly achieved by targeting PRKCA through the 7 active components of ASP. Mechanistically, ASP alleviated the course of PCOS through antioxidant, anti-inflammatory effects, and PRKCA was its potential target.

Abstract
Rhododendron is well-known for its beauty and colorful corolla. Although some high-quality whole-genome sequencing of Rhododendron has been completed, there is lack of studies on long terminal repeat (LTR) retrotransposons in Rhododendron, which limits our ability to elucidate the causes of genetic variations in Rhododendron species. The properties of the intact Rhododendron LTR retrotransposon were investigated at the genome-wide level. Based on the available data, the high-quality genomes from five species, i.e., R. griersonianum, R. simsii, R. henanense subsp. lingbaoense, R. mucronatum var. ripense and R. ovatum were selected as the identification targets with good assembly continuity. A total of 17,936 intact LTR retrotransposons were identified; they belong to the superfamilies Copia and Gypsy with 17 clades. The insertion time of these transposons was later than 120 million years ago, and the outbreak period was concentrated more recently than 30 million years ago. Phylogenetic analysis revealed that many LTR retrotransposons might originate from intraspecific duplication. The current evidences also suggests that most of the LTR retrotransposons were inserted in the interstitial part of the genes in R. griersonianum, R. simsii, R. henanense, and R. ovatum, and the functions of the inserted genes are mainly involved in starch metabolism and proteolysis etc. The effect of LTR retrotransposon on gene expression depends on its insertion site and activation. Highly expressed LTR retrotransposons tended to be younger. The activity of LTR retrotransposons may affect some stage-specific expression genes of flower development, such as leucine-rich repeat receptor-like kinase. The available results herein improve our knowledge of LTR retrotransposons in Rhododendron genomes and facilitate the further study of genetic variation and trait evolution in Rhododendron.

Abstract
Micelle Encapsulation Zinc-doped copper oxide nanocomposites (MEnZn-CuO NPs) is a novel doped metal nanomaterial prepared by our group based on Zinc doped copper oxide nanocomposites (Zn-CuO NPs) using non-micellar beam. Compared with Zn-CuO NPs, MEnZn-CuO NPs have uniform nanoproperties and high stability. In this study, we explored the anticancer effects of MEnZn-CuO NPs on human ovarian cancer cells. In addition to affecting cell proliferation, migration, apoptosis and autophagy, MEnZn-CuO NPs have a greater potential for clinical application by inducing HR repair defects in ovarian cancer cells in combination with poly (ADP-ribose) polymerase inhibitors for lethal effects.

Abstract
Polycystic ovary syndrome (PCOS), a common reproductive endocrine disorder in women of reproductive age, causes anovulatory infertility. Increased apoptosis of granulosa cells has been identified as one of the key factors contributing to abnormal follicular development. Ferredoxin 1 (FDX1) encodes a small ferredoxin that is involved in the reduction in mitochondrial cytochromes and the synthesis of various steroid hormones and has the potential to influence the function of granulosa cells. In the present study, we aimed to determine the relationship between FDX1 and follicular granulosa cell function. To this end, we investigated the difference between FDX1 expression in the granulosa cells of 50 patients with PCOS and that of the controls. Furthermore, we sought to elucidate the role and mechanism of FDX1 in PCOS granulosa cells by establishing a mouse PCOS model with dehydroepiandrosterone and KGN (a steroidogenic human granulosa cell-like tumor cell line). The results indicated significant up-regulation of FDX1 in the granulosa cells after androgen stimulation. Knockdown of FDX1 promoted the proliferation of KGN and inhibited apoptosis. Moreover, FDX1 could regulate autophagy by influencing the autophagy proteins ATG3 and ATG7. Our results demonstrated that FDX1 plays a critical role in female folliculogenesis by mediating apoptosis, autophagy, and proliferation. Therefore, FDX1 may be a potential prognostic factor for female infertility.

DESIGN Cohort study with a 2-year follow-up. SETTING AND PARTICIPANTS Data were derived from 2 waves of the CHARLS, and 4280 community-dwelling participants aged ≥ 60 years were included in the study. METHODS Sarcopenia status was defined according to the Asian Working Group for Sarcopenia 2019 (AWGS 2019) criteria. Successful aging was defined following Rowe and Kahn's multidimensional model. Pain was assessed by a self-reported questionnaire. A generalized estimating equation (GEE) was used to examine the associations. RESULTS Longitudinal results demonstrated that compared with no sarcopenia, possible sarcopenia [OR (95%CI): 0.600 (0.304~1.188)] was not significantly associated with successful aging. Pain only was strongly associated with successful aging [0.388 (0.251~0.600)], whereas the association between sarcopenia only and successful aging was weaker [0.509 (0.287~0.905)]. The likelihood of being successful aging was substantially lower in the presence of coexisting sarcopenia and pain [0.268 (0.108~0.759)]. CONCLUSIONS Both pain and sarcopenia are significant predictors for achieving successful aging among community-dwelling older adults. Early identification of sarcopenia and pain permits the implementation of treatment strategies and presents an opportunity to mitigate the risk of being unsuccessful aging.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) is one of the most common endocrine and metabolic disorders, posing a serious threat to the health of women. Herein, we aimed to explore new biomarkers and potential therapeutic targets for PCOS by employing integrated bioinformatics tools. METHODS Three gene expression profile datasets (GSE138518, GSE155489, GSE106724) were obtained from the Gene Expression Omnibus database and the differentially expressed genes in PCOS and normal groups with an adjusted p-value < 0.05 and a |log fold change (FC) | > 1.2 were first identified using the DESeq package. The weighted correlation network analysis (WGCNA) R package was used to identify clusters of highly correlated genes or modules associated with PCOS. Protein-protein interaction (PPI) network analysis and visualization of genes in the key module were performed using the STRINGdb database and the NetworkX package (edge > 5), respectively. The genes overlapping among the key module genes and PCOS-associated genes were further analyzed. Ligand molecules with strong binding energy < -10 kJ/mol to GNB3 were screened in the drug library using MTiOpenScreen. AutoDock, ChimeraX, and BIOVIA Discovery Studio Visualizer were further used to elucidate the mechanism of ligand interaction with GNB3. Finally, the relationship between GNB3 and PCOS was verified using experimental models in vivo and in vitro. RESULTS Of the 11 modules identified by WGCNA, the black module had the highest correlation with PCOS (correlation = 0.96, P = 0.00016). The PPI network of 351 related genes revealed that VCL, GNB3, MYH11, LMNA, MLLT4, EZH2, PAK3, and CHRM1 have important roles in PCOS. The hub gene GNB3 was identified by taking the intersection of PCOS-related gene sets. MTiOpenScreen revealed that five compounds interacted with GNB3. Of these five, compound 1 had the strongest binding ability and can bind amino acids in the WD40 motif of GNB3, which in turn affects the function of the G protein-coupled receptor β subunit. GNB3 was also significantly downregulated in PCOS models. CONCLUSION We identified the hub gene GNB3 as the most important regulatory gene in PCOS. We suggest that compound 1 can target the WD40 motif of GNB3 to affect related functions and must be considered as a lead compound for drug development. This study will provide new insights into the development of PCOS-related drugs.

Abstract
Background Immune dysfunction is the main characteristic of severe acute pancreatitis (SAP), and the timing of immune regulation has become a major challenge for SAP treatment. Previous reports about the time point at which the immune status of SAP changed from excessive inflammatory response to immunosuppression (hypo-inflammatory response) are conflicting. Purposes The aims of this study are to explore the immunological dynamic changes in SAP rats from the perspective of intestinal mucosal immune function, and to determine the immunoswitching point from excessive inflammatory response to immunosuppression. Methods Retrograde injection of sodium taurocholate into the pancreaticobiliary duct was applied to establish a SAP model in rats. The survival rate and the activities of serum amylase and pancreatic lipase in SAP rats were measured at different time points after model construction. The pathological changes in the pancreas and small intestines were analyzed, and the levels of intestinal pro- and anti-inflammatory cytokines and the numbers of intestinal macrophages, dendritic cells, Th1, Th2, and T regulatory cells were assessed. Meanwhile, the SAP rats were challenged with Pseudomonas aeruginosa (PA) strains to simulate a second hit, and the levels of intestinal inflammatory cytokines and the numbers of immune cells were analyzed to confirm the immunoswitching point. Results The time periods of 12–24 h and 48–72 h were the two death peaks in SAP rats. The pancreas of SAP rats showed self-limiting pathological changes, and the switching period of intestinal cytokines, and innate and adaptive immunity indexes occurred at 24–48 h. It was further confirmed that 48 h after SAP model construction was the immunoswitching point from excessive inflammatory response to immunosuppression. Conclusion The SAP rats showed characteristics of intestinal mucosal immune dysfunction after model construction, and the 48th h was identified as the immunoswitching point from excessive inflammatory response to immunosuppression. The results are of great significance for optimizing the timing of SAP immune regulation.

Abstract
Discovery of drugs rapidly and effectively is an important aspect for Alzheimer's disease (AD). In this study, a novel high-throughput screening (HTS) method aims at screening the small-molecules with amyloid-β (Aβ) binding affinity from natural medicines, based on the combinational use of biolayer interferometry (BLI) and ultra-high-performance liquid chromatography coupled with diode-array detector and quadrupole/time-of-flight tandem mass spectrometry (UHPLC−DAD-Q/TOF-MS/MS) has been firstly developed. Briefly, the components in natural medicines disassociated from biotinylated Aβ were collected to analyze their potential Aβ binding affinity by UHPLC−DAD-Q/TOF-MS/MS. Here, baicalein was confirmed to exhibit the highest binding affinity with Aβ in Scutellaria baicalensis. Moreover, polyporenic acid C (PPAC), dehydrotumulosic acid (DTA), and tumulosic acid (TA) in Kai-Xin-San (KXS) were also identified as potent Aβ inhibitors. Further bioactivity validations indicated that these compounds could inhibit Aβ fibrillation, improve the viability in Aβ-induced PC-12 cells, and decrease the Aβ content and improve the behavioral ability in Caenorhabditis elegans. The molecular docking results confirmed that PPAC, DTA, and TA possessed good binding properties with Aβ. Collectively, the present study has provided a novel and effective HTS method for the identification of natural inhibitors on Aβ fibrillation, which may accelerate the process on anti-AD drugs discovery and development.

Abstract
Backgroud: Protein kinases play an important role in cell proliferation, differentiation, mobility and cell cycle arrest etc. These enzymes act as important targets in developing anticancer agents. Over the years, a large number of protein kinase inhibitors have been discovered and developed as anticancer agents for the treatment of cancers clinically. However, the drug-resiatance and off-targeting limit their effeciancy for the treatment of human cancer. Materials and methods: Alkaloids are an important class of natural products with broad spectrum biological activities. In the past decades, numerus alkaloids with significant anticancer activity by inhibiting protein kinases were identified. In the present mini-review, we will present the key enzymes including mitogen-activated protein kinase (MAPK), phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) and janus-activated kinases/signal transducer and activator of transcription (JAK/STAT) targeted by alkaloids and highlight the special sites targeted by alkaloids on protein kinases and/or reversing drug resistance. Additionally, the challenge and prospect of developing alkaloids as new anticancer agents are also discussed. Conclusion: Alkaloids suppressed tumor growth through targeting different signaling pathways mediated by protein kinases of cancer cells. It is conceivable that novel alkaloids anticancer agents with promising clinical value will be developed in the future.

Abstract
Alnustone, a diarylheptane compound, exhibits potent growth inhibition against hepatocellular carcinoma (HCC) BEL-7402 cells. However, the underlying mechanisms associated with its anticancer activity remain unknown. In the present study, we evaluated the anticancer effect of alnustone against several human cancers focused on HCC and the possible associated mechanisms. The results showed that alnustone significantly inhibited the growth of several cancer cells by CCK-8 assay. Alnustone markedly induced apoptosis and decreased mitochondrial membrane potential in BEL-7402 and HepG2 cells. Alnustone inhibited the expression of proteins related to apoptosis and PI3K/Akt/mTOR/p70S6K pathways and generated ROS production in BEL-7402 and HepG2 cells. Moreover, N-acetyl-L-cysteine (NAC, a ROS inhibitor) could significantly reverse the effects of alnustone on the growth inhibition of BEL-7402 and HepG2 cells and the expression of proteins related to apoptosis and PI3K/Akt/mTOR signaling pathway in HepG2 cells. Furthermore, alnustone significantly inhibited tumor growth of HepG2 xenografts, obviously induced apoptosis in the tumor tissues and improved the pathological condition of liver tissues of mice in vivo. The study provides evidence that alnustone is effective against HCC via ROS-mediated PI3K/Akt/mTOR/p70S6K pathway and the compound has the potential to be developed as a novel anticancer agent for the treatment of HCC clinically.

Abstract
Enolase 1 (ENO1) is a moonlighting protein, function as a glycolysis enzyme, a plasminogen receptor and a DNA binding protein. ENO1 play an important role in the process of cancer development. The transcription, translation, post-translational modifying activities and the immunoregulatory role of ENO1 at the cancer development is receiving increasing attention. Some function model studies have shown that ENO1 is a potential target for cancer treatment. In this review, we provide a comprehensive overview of the characterization, function, related transduction cascades of ENO1 and its roles in the pathophysiology of cancers, which is a consequence of ENO1 signaling dysregulation. And the development of novels anticancer agents that targets ENO1 may provide a more attractive option for the treatment of cancers. The data of sarcoma and functional cancer models indicates that ENO1 may become a new potential target for anticancer therapy.

Abstract
Mere15, an anticancer polypeptide with a molecular weight of 15 kDa, is extracted from the marine species Meretrix meretrix. A previous study in our laboratory has confirmed that Mere15 displays a potent antitumor activity. However, the underlying mechanism of Mere15 still remains unclear. The effect of Mere15 on the growth of a variety of tumor cells was measured by the CCK-8 assay. Hoechst33342/PI double staining and flow cytometry assays were used to detect the apoptosis status of cancer cells. Western blotting was used to detect the expression of apoptosis-related proteins, migration and invasion-related protein, and the changes in the PI3K/Akt/mTOR signaling pathway-related proteins. Treatment with Mere15 inhibited cancer cell growth significantly. Scratch wound-healing assay, as well as Transwell experiments, revealed that the polypeptide was able to inhibit the invasion and migration of NSCLC cells significantly. Western blotting analysis confirmed that treatment with Mere15 inhibited the phosphorylation of PI3K, Akt, and mTOR significantly. The effects of Mere15 were also evaluated in the presence of an activator or inhibitor of the PI3K/Akt/mTOR pathway. Downregulated expression of MMP-2, MMP-9, and Snail, and increased expression of E-cadherin were also found in cells treated with Mere15. In vivo study revealed that Mere15 inhibited tumor growth significantly in xenograft nude mice bearing NCI-H460 cancer cells. The study provides evidence that Mere15 has the potential to be developed as a novel antimetastatic agent for the treatment of NSCLC patients. The work also provides further evidence that targeting PI3K/Akt/mTOR pathway is an important strategy for overcoming cancer metastasis.

Abstract
Neuroinflammation is considered as a detrimental factor in neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), etc. Nucleotide-binding oligomerization domain-, leucine-rich repeat- and pyrin domain-containing 3 (NLRP3), the most well-studied inflammasome, is abundantly expressed in microglia and has gained considerable attention. Misfolded proteins are characterized as the common hallmarks of neurodegenerative diseases due to not only their induced neuronal toxicity but also their effects in over-activating microglia and the NLRP3 inflammasome. The activated NLRP3 inflammasome aggravates the pathology and accelerates the progression of neurodegenerative diseases. Emerging evidence indicates that microglial autophagy plays an important role in the maintenance of brain homeostasis and the negative regulation of NLRP3 inflammasome-mediated neuroinflammation. The excessive activation of NLRP3 inflammasome impairs microglial autophagy and further aggravates the pathogenesis of neurodegenerative diseases. In this review article, we summarize and discuss the NLRP3 inflammasome and its specific inhibitors in microglia. The crucial role of microglial autophagy and its inducers in the removal of misfolded proteins, the clearance of damaged mitochondria and reactive oxygen species (ROS), and the degradation of the NLRP3 inflammasome or its components in neurodegenerative diseases are summarized. Understanding the underlying mechanisms behind the sex differences in NLRP3 inflammasome-mediated neurodegenerative diseases will help researchers to develop more targeted therapies and increase our diagnostic and prognostic abilities. In addition, the superiority of the combined use of microglial autophagy inducers with the specific inhibitors of the NLRP3 inflammasome in the inhibition of NLRP3 inflammasome-mediated neuroinflammation requires further preclinical and clinical validations in the future.

Abstract
Purpose MiR-34a, which acts as an important tumor suppressor gene, plays an important role in pancreatic cancer. However, the therapeutic application of miR-34a is limited by the lack of an effective delivery system. In the present study, we synthesize exosomes-coated miR-34a (exomiR-34a), and the anticancer effect of exomiR-34a was evaluated in pancreatic cancer. Materials and Methods An ultrasound approach was used to synthesize exomiR-34a, and its transfection efficiency was examined by confocal microscopy and flow cytometry. The level of miR-34a and its targeted gene Bcl-2 was detected by real-time quantitative PCR (qRT-PCR). MTT analysis was performed to determine the effect of exomiR-34a on the growth of pancreatic cancer cells. Annexin-V/PI double staining and Western blot analysis were carried out to determine the apoptosis of the pancreatic cancer cells. The xenograft nude mice model bearing human pancreatic cancer Panc28 cells was used to determine the antitumor effect of exomiR-34a in vivo. Results The exomiR-34a could cross the cell membrane efficiently, and downregulated the expression of the targeted gene Bcl-2. Treatment with exomiR-34a inhibited the growth of the pancreatic cancer cells significantly and the nanoparticles also induced apoptosis in cancer cells via affecting the expression of apoptotic-related genes. In vivo study using xenograft nude mice bearing Panc28 cancer cells revealed that exomiR-34a suppressed the growth of tumors significantly. Conclusion ExomiR-34a can inhibit the growth of pancreatic cancer both in vitro and in vivo. Targeting miR-34a is a promising strategy for the treatment of pancreatic cancer. ExomiR-34a has the potential to be developed as a novel anticancer agent for the treatment of human pancreatic malignancy.

Abstract
Enzalutamide, an androgen receptor inhibitor, has been clinically approved for the treatment of metastatic castration-resistant prostate cancer (CRPC) in the United States. However, patients only benefit from enzalutamide for a short period of time as resistance may develop. Therefore, it is vital to develop a novel strategy to overcome enzalutamide resistance. Ras-related C3 botulinum toxin substrate 1 (Rac1), which is commonly upregulated in human cancer types, has been recognized as a key molecular component in tumorigenesis, invasion and metastasis. However, the role of Rac1 in enzalutamide-resistance in prostate cancer (PCa) remains unknown. In the present study, Rac1 was demonstrated to be upregulated in enzalutamide-resistant PCa cells, and Rac1 knockdown inhibited enzalutamide-resistant cell proliferation and colony formation. Western blotting results indicated that enzalutamide treatment downregulated the expression levels of JNK and activated transcription factor 2, as well as enhanced the Bax/Bcl-2 ratio and induced cleavage of poly-ADP ribose polymerase. Moreover, knockdown of Rac1 in MR49F cells significantly inhibited cell migration and invasion via the downregulation of Snail and the upregulation of E-cadherin. The results of a nude mouse xenograft tumor model using 22RV1 cells demonstrated that enzalutamide inhibited tumor growth after Rac1 knockdown dramatically, compared to vehicle and single treatment groups. Therefore, the present study provided novel evidence that Rac1 may serve a crucial role in enzalutamide resistance, and that targeting Rac1 may be a potential approach for the treatment of CRPC.

Abstract
Objective: To investigate effect of the contact surface between the bridge and the adjacent teeth on the stress distribution of the implant and bone tissue and the displacement of the prosthesis in the cantilever fixed implant bridge restoring missing mandibular central incisors. Methods: Two-dimensional images of the mandible and dentition in healthy adults were obtained using CT data. A three-dimensional finite element model of cantilever fixed bridge supported by implants with mandibular central incisor was established by computer reconstruction technique.The contact surface between the bridge and the adjacent natural tooth was designed as "oval" and "trapezoid". The "trapezoid" has a slightly smaller median diameter on the labial side and a slightly larger medial diameter on the lingual side. Loading of 120 N was applied on the tangential margin of the middle line of the long axis of the bridge 41. The direction was set at 0°, which was parallel to the long axis of the tooth and downward. The buccal to lingual and downward angles were 30°, 45° and 60°, respectively, perpendicular to the long axis of the tooth and 90° to the lingual side.The stress distribution of the implant and surrounding bone tissue and the displacement of the prosthesis were compared between the two models. Results: Under axial and buccolingual loading, the maximum equivalent stress peak in the implant and surrounding bone tissue in the cantilever with trapezoidal contact surface design and the maximum displacement of the prosthesis were lower. Moreover, the distribution of stress was more balanced and the concentration range of stress was smaller. With the loading angle increasing, this trend was more obvious. When loading angle increased to 90°, the maximum equivalent stress and the maximum displacement of the elliptic contact surface model implant and surrounding bone tissue were 196 and 101 MPa and 0.196 mm, respectively, while the trapezoidal contact surface model were 157 and 72 MPa and 0.164 mm, respectively. Conclusions: The trapezoidal contact surface of the bridge and the adjacent teeth in the cantilever fixed bridge supported by implants with mandibular central incisor is beneficial to reduce the impact of the leverage on the implant and surrounding bone tissue.

Abstract
Cloves (Syzygium aromaticum), a traditional Chinese medicinal herb, displays broad biological activity. In the present study, the aqueous extract of clove (AEC) was prepared, and its anticancer affects were studied. 3-(4,5-Dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetra-zolium (MTS) analysis revealed that AEC was able to inhibit cancer cell growth in vitro on several cancer cell lines; the IC50 is around 150 μg/ml for human pancreatic ASPC-1 and human colon HT-29 cancer cells. Treatment of the cancer cells with AEC also diminished the colony formation significantly in both human pancreatic ASPC-1 cancer cells and human colon HT-29 cancer cells. In vivo study revealed that AEC inhibited the tumor growth significantly in HT-29 xenograft mice model. Transmission electron microscope, flow cytometry assay, and fluorescence microscope analysis confirmed that AEC is capable of inducing cell autophagy. Further study showed that AMPK/ULK pathway plays an important role in AEC-induced autophagy in cancer cells. Analysis of AEC components was performed by liquid chromatograph mass spectrometer approach, and more than nine constitutes were identified in AEC fraction. The study provides evidence that AEC has potential to be developed as a novel anticancer agent or as an adjuvant in cancer chemotherapy.

Abstract
Zinc doped copper oxide nanocomposites (Zn-CuO NPs) is a novel doped metal nanomaterial synthesized by our group using the sonochemical method. Our previous studies have shown that Zn-CuO NPs could inhibit cancer cell proliferation by inducing apoptosis via ROS-mediated pathway. In the present study, we studied the anticancer effect of Zn-CuO NPs on human pancreatic cancer cells. MTS assay revealed that Zn-CuO NPs was able to inhibit cancer cell growth. TEM, flow cytometry and fluorescence microscope analysis showed that Zn-CuO NPs induced autophagy significantly; the number of autophagosomes increased obviously in cells treated with Zn-CuO NPs. Western blot analysis revealed that treatment with the NPs resulted in activation of AMPK/mTOR pathway in both AsPC-1 and MIA Paca-2 cells in dose dependent manners. Moreover, in the presence of AMPK activator AMPKinone, the protein level of p-AMPK, p-ULK1, Beclin-1 and LC3-II/LC3-I increased, while the protein expression of p-AMPK, p-ULK1, Beclin-1 and LC3-II/LC3-I decreased in the presence of AMPK inhibitor Compound C. In vivo study using xenograft mice revealed that Zn-CuO NPs significantly inhibited tumor growth with low toxicity. Our study confirms that Zn-CuO NPs inhibit the tumor growth both in vitro and in vivo for pancreatic cancer. AMPK/mTOR pathway plays an important role in the NPs induced inhibition of tumor growth.

Abstract
AIM To investigate the antitumor effects and action mechanism of Zn-doped CuO nanocomposites (Zn-CuONPs). MATERIALS & METHODS Therapeutic effects and mechanisms of Zn-CuONPs were investigated both in vitro and in vivo. RESULTS Zn-CuONPs could inhibit tumor growth both in vitro and in vivo significantly. Zn-CuONPs treatment resulted in cytotoxicity, reactive oxygen species (ROS) production, DNA damage, apoptosis and autophagy. ROS scavenger N-acetylcysteine attenuated all of the above effects induced by Zn-CuONPs. N-acetylcysteine also restored the effects of Zn-CuONPs on protein expressions related to apoptosis, autophagy and NF-κB pathways. NF-κB pathway inhibitor pyrrolidine dithiocarbamate significantly attenuated Zn-CuONPs induced apoptosis and autophagy. CONCLUSION Our data demonstrated that Zn-CuONPs could inhibit tumor growth both in vitro and in vivo by ROS-dependent apoptosis and autophagy cross-linked by NF-κB pathways.

Abstract
BACKGROUND CS5931, a novel marine peptide, was extracted and purified from the sea squirt Ciona savignyi. Our previous studies showed that recombinant CS5931 can significantly inhibit tumor growth both in vitro and in vivo. However, its molecular targets have not been elucidated. METHODS The target of the recombinant CS5931 was identified by pull-down/SDS-PAGE/MS approaches and confirmed by Western blot and surface plasmon resonance analysis. Transwell experiments were used to detect whether the recombinant CS5931 inhibited cancer migration and invasion via enolase 1. Dot blotting analysis was used to detect the effect of CS5931 on the interaction of enolase 1 and plasminogen, as well as enolase 1 and uPA/uPAR. RESULTS Enolase 1 was identified as the molecular target interacting with the recombinant CS5931. Transwell experiment showed that the recombinant CS5931 was able to inhibit migration and invasion of HCT116 cells and enolase 1 overexpression reversed the effects of the recombinant CS5931 on migration and invasion of cancer cells. Dot blotting analysis revealed that the recombinant CS5931 interfered with the interaction among enolase 1 and plasminogen as well as enolase 1 and uPA/uPAR. CONCLUSION Our present study showed that the recombinant CS5931 could inhibit tumor invasion and matastasis via interacting with enolase 1, suggesting that the new marine polypeptide CS5931 possesses the potential to be developed as a novel anticancer agent.

Abstract
Maslinic acid (MA), a natural pentacyclictriterpene, displays cytotoxic activity on various types of cancer cells. However, its underlying mechanism is unclear. In this study, we assessed the effect of MA on autophagy of human pancreatic cancer cells, and the potential autophagic pathway was presented. MA inhibited the proliferation and induced autophagy of Panc-28 cells by altering the expressions of autophagy related proteins. SDS-PAGE analysis revealed that one protein band was significantly down-regulated in cells treated with MA, and the band was identified as heat shock protein HSPA8 as analyzed using Western blot and MS, MS/MS approaches. HSPA8 knockdown could significantly inhibit cell viability and enhance the cytotoxic effects of MA, whereas HSPA8 overexpression was able to enhance cell viability, diminishing the effects of MA. Western blot analysis indicated that the effect of MA on the expression of autophagy related genes was increased significantly in cells treated with HSPA8 inhibitor VER-155008, whereas HSPA8 inducer geranylgeranylacetone antagonized the effects of MA. Our study provides evidence that MA is able to induce of autophagy via down-regulation of HSPA8 in Panc-28 cells.

Abstract
Granulin A (GRN A), a peptide with a molecular 6 kDa, is derived from proteolysis of progranulin (PGRN). Previous study in our laboratory has shown that GRN A is able to inhibit cancer cell growth significantly. In the present study, we confirmed that GRN A can bind to α-enolase (ENO1) specifically as analyzed using Pull-down/MS approaches. The interaction of GRN A with ENO1 was further confirmed by Western blotting and Surface plasmon resonance (SPR) analysis. Treatment of human HepG-2 cells with GRN A inhibited cancer cell growth as well as migration and invasion of cancer cells as analyzed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazoliumbromide (MTT) and Scratch wound healing assay as well as Transwell experiments. Additionally, GRN A treatment results in augmentation of glucose uptake in cancer cells. Further study reveals that higher expression of ENO1 reversed the inhibitory effects of GRN A on migration and invasion of HepG-2 cells. The increase of glucose uptake, as well as the expression of apoptosis-related genes, is also reversed in cells overexpressing ENO1. The study provides solid evidence that there is the interaction between GRN A and ENO1 and the interaction is responsible for the effects of GRN A on glucose uptake as well as cancer cell migration and invasion.

Abstract
OBJECTIVE The long non-coding RNAs (lncRNAs) study has gradually become one of the hot topics in the field of RNA biology. However, little is known about the pathological role of lncRNA TUG1 in clear cell renal cell carcinoma (ccRCC) patients. This study attempted to investigate the association of lncRNA TUG1 expression with progression and prognosis in ccRCC patients. PATIENTS AND METHODS Using qRT-PCR, the expression of TUG1 was measured in 203 ccRCC tissues and 45 adjacent non-cancerous tissues. Then, the relationships between TUG1 level and the clinicopathological factors of patients with ccRCC were analyzed. The prognostic significance was evaluated using Kaplan-Meier and Cox regression analyses. RESULTS The relative level of TUG1was significantly higher in ccRCC tissues compared to the adjacent non-tumor tissues (p < 0.01). Furthermore, TUG1 was associated significantly with histological grade, tumor stage, lymph node metastasis and distant metastasis (all p < 0.05). Interestingly, Kaplan-Meier analysis showed that higher TUG1 expression levels were associated with a shorter overall survival (p < 0.001) in ccRCC patients. Cox proportional hazards analysis showed that high TUG1 expression was an independent prognostic marker of poor outcome. CONCLUSIONS These findings suggested that TUG1 may act as a tumor promoter in ccRCC and could serve as a potential therapeutic target for this tumor.

Abstract
Strategies to identify tumors at highest risk for treatment failure are currently under investigation for patients with bladder cancer. We demonstrate that flow cytometric detection of poorly differentiated basal tumor cells (BTCs), as defined by the co-expression of CD90, CD44 and CD49f, directly from patients with early stage tumors (T1-T2 and N0) and patient-derived xenograft (PDX) engraftment in locally advanced tumors (T3-T4 or N+) predict poor prognosis in patients with bladder cancer. Comparative transcriptomic analysis of bladder tumor cells isolated from PDXs indicates unique patterns of gene expression during bladder tumor cell differentiation. We found cell division cycle 25C (CDC25C) overexpression in poorly differentiated BTCs and determined that CDC25C expression predicts adverse survival independent of standard clinical and pathologic features in bladder cancer patients. Taken together, our findings support the utility of BTCs and bladder cancer PDX models in the discovery of novel molecular targets and predictive biomarkers for personalizing oncology care for patients.

Abstract
Multiple infections are commonly found in practical shrimp culture and may cause more serious consequences than infections by one pathogen only. Therefore, this study was conducted to evaluate the effect of multiple infections with white spot syndrome virus (WSSV) and Vibrio anguillarum on Pacific white shrimp Litopenaeus vannamei (L.), mortality, WSSV replication in vivo and host immune response. In the WSSV single-infection group (WSSV load, 2 × 10(2) copies μL(-1)), mean cumulative mortality was 29.2%. In the V. anguillarum single-infection group, cumulative mortality was 12.5% when shrimp were challenged by 10(5) CFU mL(-1) of bacteria. In the co- and super-infection groups, 37.5% and 50% cumulative mortalities, respectively, were observed at a lower bacterial concentration of 10(3) CFU mL(-1), suggesting that shrimp with multiple infections died earlier and more frequently than singly infected shrimp. WSSV load after injection was tracked over time by TaqMan quantitative PCR. WSSV load increased more rapidly in the multiple-infection groups than in the single-infection group. Additionally, mRNA expression of the genes encoding prophenoloxidase 1 and 2, which are closely involved in innate immunity in shrimp, was down-regulated more extensively in multiple-infection groups than in single-infection groups, as indicated by quantitative reverse-transcription PCR.

Abstract
Shewanella marisflavi isolate AP629 is described as a novel pathogen of sea cucumber. The LD(50) values (14 days) in sea cucumber, mice and swordtail fish were 3.89 × 10(6) , 6.80 × 10(4) and 4.85 × 10(4) CFU g(-1) body weight, respectively. Studies on S. marisflavi were conducted, including morphology, physiological and biochemical characteristics, haemolysis, whole-cell protein and 16S rDNA gene sequence. Colonies of S. marisflavi appeared faint red on marine agar and green on thiosulphate-citrate-bile salt-sucrose media. Shewanella marisflavi had polar flagella. The cells were Gram-negative, oxidase- and catalase-positive and not sensitive to O/129. The bacterium exhibited β-haemolysis on sheep blood agar and produced H(2) S. Shewanella marisflavi survived and grew at 4-35°C, pH 6.0-9.2 and in the presence of 0-8% NaCl. The whole-cell proteins included 13 discrete bands, and proteins of molecular weight 87, 44 and 39 kDa were found in all five strains of Shewanella spp. The difference in 16S rDNA gene sequences in S. marisflavi was at the 446 bp site: S. marisflavi (KCCM 41822) - G, isolate AP629 - A. This is the first report that Shewanella is pathogenic to sea cucumber.

Abstract
e22050 Background: EGFR mutations may accumulate during multistage progression of bronchioloalveolar carcinoma (BAC), leading to heterogeneity within the tumor. Moreover, intrapulmonary emersions are the predominant sites of BAC progression in the absence of other distant metastases. In cases of emerging bilateral lung lesions during the follow-up to complete resection, the issue of how to differentiate between lesions originating from multifocal BACs or distant metastases/local recurrence is an important and unresolved issue. This study was performed to determine whether sequential adenocarcinoma with BAC features emerges in the lung field arises from a single clone or multiple clones in the same individual. Methods: Samples of adenocarcinomas exhibiting various degrees of BAC were obtained by thoracotomy. Sequential specimens were obtained on detection of novel lesions in the lung field. Genomic DNA was extracted from the specimens, and the presence of activating mutations in EGFR was analyzed by direct sequencing. Our pathological findings, sequential imaging, and EGFR sequence data were compared to monitor evidence of cancer evolution. Results: Based on an analysis of EGFR in tumor specimens from 428 lung cancer patients, fifteen cases of sequential BAC-related adenocarcinoma obtained by thoracotomy were identified. Together with alterations in BAC/adenocarcinoma components, the EGFR-TKI untreated series with at least one episode of EGFR-activating mutations represented three typical models: no significant EGFR evolution for a single clone, genetic alterations from mutant to wild-type EGFR for multifocal lesions, and a switch from wild-type to mutant EGFR, which might exhibit uncertain circumstances of cancer progression. Conclusions: Genetic analysis in conjunction with pathological and radiological diagnoses can be used to explore the origin of multifocal BAC. The single clone model indicates subsequent disease progression, whereas genetic alterations from mutations to wild-type EGFR are suggestive of secondary primary carcinoma. When additional lesions emerge after radical resection of BAC-related lung cancer, sequential tumor samples should be obtained for further evaluation. No significant financial relationships to disclose.

Abstract
Small field sizes are increasingly becoming important in radiotherapy particularly since the introduction of intensity-modulated radiation therapy (IMRT) techniques. It is normally a challenging task to reliably measure the delivered dose and to determine its distribution in a medium for such small fields using conventional-type dosimeters such as gas ionisation chambers. Recently, attempts have been made to use films, but they are not tissue equivalent, they measure the dose only in two dimensions and they are not as responsive to radiations. In the present work, polyacrylamide gel (PAG) dosimeters are employed to measure the dose and its distribution in three dimensions for very small field sizes, such as those typically used in stereotactic radiosurgery. Field sizes of 6 x 6 and 18 x 18 mm in width are investigated. The results show an agreement with radiochromic film and ionisation diode measurements, with some variation in measured doses near the edge of the field, where the gel data decreases more rapidly than the other methods.
