Abstract
Early B cell factor 1 (EBF1) has been identified as an upstream transcription factor of the potential oncogene PNO1 and is involved in the growth of colorectal cancer (CRC) cells. However, its expression, biological function, and underlying mechanism of action in most solid tumors remain largely unknown. We postulated that EBF1 has a role in the pathophysiology of CRC. Analysis of EBF1 mRNA expression in CRC tumor samples from several public databases and directly from banked tissues revealed that EBF1 mRNA expression is lower in CRC tissue compared to non-cancerous colorectal tissue. Survival analysis of multiple datasets revealed that low EBF1 expression was correlated with shorter overall survival, relapse-free survival, and event-free survival in CRC patients. Transduction of lentivirus encoding full length EBF1 followed by in vitro and in vivo assays demonstrated that EBF1 over-expression in CRC cell lines suppresses cell growth by inhibiting cell viability, cell survival, and induces cell cycle arrest and apoptosis. Mechanistic investigation indicated that EBF1 over-expression down-regulates PNO1 mRNA and protein expression, as well as transcriptional activity while up-regulating the expression of p53 and p21 proteins. These findings suggest that EBF1 is a novel potential tumor suppressor in CRC with prognostic value for the identification of patients at high-risk of relapse.

Abstract
Intestinal mucosal barrier dysfunction is involved in the pathogenesis of inflammatory bowel disease, including ulcerative colitis (UC). Xinhuang tablets (XHTs) have been prescribed for several kinds of inflammatory diseases, including UC, whereas its possible underlying molecular mechanisms had never been explored. Mouse model of UC was constructed by DSS treatment and followed by XHT treatment. Disease activity index, histopathological of colonic tissue, tumor necrosis factor-alpha (TNF-α), and serum amyloid A (SAA) levels in serum were further assessed. The underlying mechanism was further explored by determination of the expression of epithelial tight junction-related protein. XHT administration ameliorated dextran sulfate sodium (DSS)-induced clinical symptoms, colonic histological injury, and decreased the circulating levels of TNF-α and SAA. Moreover, XHT treatment significantly increased the protein levels of zona occludens (ZO)-1, whereas decreased the levels of phosphorylation of Elk-1. In conclusion, this study confirmed the therapeutic effects of XHT treatment on UC in a DSS-induced mouse model, and indicated that by increasing expression of epithelial tight junctions and decreasing phosphorylation of Elk-1 might be one of the underlying mechanisms of XHT treatment on UC.

Abstract
Abstract
The high-speed dynamics of a hybrid distributed feedback semiconductor laser heterogeneously integrated onto silicon is experimentally investigated in the presence of external optical feedback. The laser fabrication relies on a proper modal engineering in which light is generated in the III–V material and stored in the low-loss silicon region in order to substantially enhance the quality factor of the cavity resonator. In this work, the hybrid laser is found to be insensitive to parasitic reflections leading to a 10 Gbps floor-free transmission with a power penalty no greater than 1.5 dB at room temperature. As a conclusion, owing to the large quality factor, a high coherence collapse level is unveiled in such laser indicating its vast potential to serve as an alternative solution for the development of isolator-free applications in future photonics integrated circuits. A qualitative interpretation is also provided by linking the standard feedback equations to the quality factor of the resonator.

Abstract
The Qingda granule (QDG) formulation was simplified from the Qingxuan Jiangya Decoction, which has been used in China to treat hypertension for decades. However, the molecular mechanisms of QDG in antihypertension remain largely unknown. Therefore, we evaluated the therapeutic efficacy of QDG against elevated blood pressure and explored its underlying mechanism. QDG treatment decreased elevated blood pressure and increased the vascular elasticity of thoracic aortic rings to KCl stimulation in spontaneously hypertensive rats. QDG treatment increased the relaxation of isolated thoracic aortic rings precontracted with norepinephrine (NE) or KCl in an endothelium-independent manner, which was attenuated by treatment with verapamil, but not by treatment with TEA, 4-AP, Gli, or BaCl2. Moreover, QDG pretreatment attenuated the CaCl2-induced constriction of isolated thoracic aortic rings in K- or NE-containing Ca-free solutions. In addition, QDG pretreatment significantly inhibited the influx of Ca in A7r5 cells induced by a K- or NE-containing Ca solution and decreased the levels of p-AKT but had no effect on levels of total AKT protein in isolated thoracic aortic rings. Considering these results, QDG treatment attenuated elevated blood pressure and promoted the vasorelaxation of thoracic aortic rings by inhibiting the influx of Ca and activating the AKT pathway.

Abstract
OBJECTIVE Inflammatory cytokines secretion is an important reason to promote lung tissue inflammation in acute lung injury (ALI). High mobility group box 1 (HMGB-1) and its receptor for advanced glycation end products (RAGEs) play a role in ALI. Ketamine can significantly alleviate ALI, whereas its specific mechanism has not been fully elucidated. MATERIALS AND METHODS A total of 60 male Wistar rats were equally randomly divided into three groups, including ALI group which was established by 10 mg/kg LPS femoral vein injection, ketamine group which was constructed by 50 mg/kg ketamine femoral vein injection based on ALI model, and control group. Blood gas analysis was applied to detect arterial blood oxygen partial pressure (PaO2) and pH. Lung tissue wet/dry weight ratio (W/D), myeloperoxidase (MPO) and superoxide dismutase (SOD) activity were detected. Real-time PCR and ELISA were used to test HMGB-1 expression in lung tissue and serum. RAGE and NF-κB changes were determined by Real-time PCR and Western blot. RESULTS Compared with control, ALI group presented decreased PaO2 and PH, elevated W/D, enhanced MPO activity, declined SOD activity, upregulated HMGB-1 mRNA, increased HMGB-1 secretion, and increased RAGE and NF-κB mRNA and protein (p < 0.05). Ketamine treatment significantly elevated PaO2 and PH, reduced W/D, declined MPO activity, enhanced SOD activity, inhibited HMGB-1 mRNA and secretion, and downregulated RAGE and NF-κB mRNA and protein (p < 0.05). CONCLUSIONS Ketamine can alleviate LPS induced lung injury through inhibiting HMGB1-RAGE level. It could be treated as a new choice for ALI treatment.

Abstract
Despite advancements in treatment regimens, the mortality rate of patients with oral tongue squamous cell carcinoma (OTSCC) is high. In addition, the signaling pathways and oncoproteins involved in OTSCC progression remain largely unknown. Therefore, the aim of the present study was to identify specific prognostic marker for patients at a high risk of developing OTSCC. The present study used four original microarray datasets to identify the key candidate genes involved in OTSCC pathogenesis. Expression profiles of 93 OTSCC tissues and 76 normal tissues from GSE9844, GSE13601, GSE31056 and GSE75538 datasets were investigated. Differentially expressed genes (DEGs) were determined, and gene ontology enrichment and gene interactions were analyzed. The four GSE datasets reported five upregulated and six downregulated DEGs. Five upregulated genes (matrix metalloproteinase 1, 3, 10 and 12 and laminin subunit gamma 2) were localized in the extracellular region of cells and were associated with extracellular matrix disassembly. Furthermore, analysis for The Cancer Genome Atlas database revealed that the aforementioned five upregulated genes were also highly expressed in OTSCC and head and neck squamous cell carcinoma tissues. These results demonstrated that the five upregulated genes may be considered as potential prognostic biomarkers of OTSCC and may serve at understanding OTSCC progression. Upregulated DEGs may therefore represent valuable therapeutic targets to prevent or control OTSCC pathogenesis.

Abstract
The RNA-binding protein PNO1 is critical for ribosome biogenesis, but its potential role in cancer remains unknown. In this study, online data mining, cDNA, and tissue microarrays indicated that PNO1 expression was higher in colorectal cancer tissue than in noncancerous tissue, and its overexpression was associated with worse patient survival. Gain-of-function and loss-of-function studies demonstrated that PNO1 knockdown suppressed growth of colorectal cancer cells in vitro and in vivo, while PNO1 overexpression promoted colorectal cancer cell proliferation in vitro. In colorectal cancer cells expressing wild-type p53, PNO1 knockdown enhanced expression of p53 and its downstream gene p21, and reduced cell viability; these effects were prevented by p53 knockout and attenuated by the p53 inhibitor PFT-α. Moreover, PNO1 knockdown in HCT116 cells decreased levels of 18S rRNA, of 40S and 60S ribosomal subunits, and of the 80S ribosome. It also reduced global protein synthesis, increasing nuclear stress and inhibiting MDM2-mediated ubiquitination and p53 degradation. Overexpressing EBF1 suppressed PNO1 promoter activity and decreased PNO1 mRNA and protein, inhibiting cell proliferation and inducing cell apoptosis through the p53/p21 pathway. In colorectal cancer tissues, the expression of EBF1 correlated inversely with PNO1. Data mining of online breast and lung cancer databases showed increased PNO1 expression and association with poor patient survival; PNO1 knockdown reduced cell viability of cultured breast and lung cancer cells. Taken together, these findings indicate that PNO1 is overexpressed in colorectal cancer and correlates with poor patient survival, and that PNO1 exerts oncogenic effects, at least, in part, by altering ribosome biogenesis. SIGNIFICANCE: This study identifies the ribosome assembly factor PNO1 as a potential oncogene involved in tumor growth and progression of colorectal cancer.

Abstract
Aberrant activation of platelets has a critical role in thrombotic vascular events, including atherosclerosis, arterial thrombosis and myocardial infarction. The process of platelet activation is associated with multiple intracellular signaling pathways, including the phosphoinositide 3‑kinase/AKT serine/threonine kinase (Akt) pathway. The well‑known medicinal herb Rhizoma Ligusticum Wallichii (RLW) has long been used in China to clinically treat various cardiovascular disorders. As the most pharmacologically active component of RLW, ligustrazine has been demonstrated to possess a potent antiplatelet activity. However, the precise mechanisms mediating the bioactivities of ligustrazine have not been thoroughly elucidated. The present study evaluated the effects of ligustrazine hydrochloride (LH; the clinical‑grade form of ligustrazine) on platelet activation and investigated the underlying molecular mechanisms. In vitro and ex vivo platelet activation models were used, established by stimulating rat platelet‑rich plasma either with the platelet activator adenosine diphosphate (ADP) or with the specific Akt pathway activator insulin‑like growth factor‑1 (IGF‑1). The results demonstrated that treatment with LH significantly and dose‑dependently inhibited ADP‑induced platelet aggregation, in addition to thromboxane A2 (TXA2) secretion and intracellular Ca2+ mobilization in platelets, in vitro and ex vivo. In addition, LH markedly suppressed ADP‑induced Akt phosphorylation in vitro and ex vivo. Furthermore, LH markedly inhibited IGF‑1‑induced Akt phosphorylation, platelet aggregation, TXA2 formation and Ca2+ mobilization in vitro. Finally, LH was able to reverse adrenaline‑induced shortening of bleeding time. Taken together, these results suggested that ligustrazine possesses a broad range of antiplatelet activities without apparent hemorrhagic side-effects, and suppression of Akt signaling may be one of the mechanisms by which ligustrazine exerts its antiplatelet activities.

Abstract
Interleukin‑6 (IL‑6)/signal transducer and activator of transcription 3 (STAT3) pathway plays essential roles in the development of inflammatory diseases including ulcerative colitis (UC). Therefore, suppression of IL‑6/STAT3 signaling provides a promising therapeutic strategy in UC. Pien Tze Huang (PZH), a well‑known traditional Chinese formula, has been used in China and Southeast Asia for centuries as a folk remedy for various inflammatory diseases. However, the molecular mechanisms of its anti‑inflammatory effects remain to be elucidated. In the present study, we generated a mouse colitis model by using dextran sulfate sodium (DSS) and evaluated the therapeutic efficacy of PZH against UC by observing the clinical manifestations. We found that PZH obviously alleviated DSS‑induced colitis symptoms, including body weight loss, rectal bleeding and stool consistency. In addition, administration of PZH profoundly prevented DSS‑induced colon shortening, and ameliorated colonic histopathological changes such as mucosal ulceration, infiltration of inflammatory cells, crypt distortion and hyperplastic epithelium. Moreover, PZH markedly inhibited the serum level of the inflammatory biomarker serum amylase A (SAA) in UC mice. Furthermore, PZH treatment significantly inhibited DSS‑induced expression of IL‑6 in colon tissues. Finally, the increased phosphorylation level of STAT3, induced either by DSS in experimental mice or by IL‑6 in the differentiated human colorectal carcinoma cells, was significantly suppressed by PZH. These results suggest that the inhibition of IL‑6/STAT3 signaling is a potential mechanism by which PZH is used in the treatment of UC.

Abstract
Bromodomain extraterminal protein (BETP) inhibitors transcriptionally repress oncoproteins and nuclear factor-κB (NF-κB) target genes that undermines the growth and survival of mantle cell lymphoma (MCL) cells. However, BET bromodomain inhibitor (BETi) treatment causes accumulation of BETPs, associated with reversible binding and incomplete inhibition of BRD4 that potentially compromises the activity of BETi in MCL cells. Unlike BETi, BET-PROTACs (proteolysis-targeting chimera) ARV-825 and ARV-771 (Arvinas, Inc.) recruit and utilize an E3-ubiquitin ligase to effectively degrade BETPs in MCL cells. BET-PROTACs induce more apoptosis than BETi of MCL cells, including those resistant to ibrutinib. BET-PROTAC treatment induced more perturbations in the mRNA and protein expressions than BETi, with depletion of c-Myc, CDK4, cyclin D1 and the NF-κB transcriptional targets Bcl-xL, XIAP and BTK, while inducing the levels of HEXIM1, NOXA and CDKN1A/p21. Treatment with ARV-771, which possesses superior pharmacological properties compared with ARV-825, inhibited the in vivo growth and induced greater survival improvement than the BETi OTX015 of immune-depleted mice engrafted with MCL cells. Cotreatment of ARV-771 with ibrutinib or the BCL2 antagonist venetoclax or CDK4/6 inhibitor palbociclib synergistically induced apoptosis of MCL cells. These studies highlight promising and superior preclinical activity of BET-PROTAC than BETi, requiring further in vivo evaluation of BET-PROTAC as a therapy for ibrutinib-sensitive or -resistant MCL.

Abstract
Hepatocellular carcinoma (HCC) is characterized by uncontrolled proliferation and the deregulation of apoptotic signaling, although its molecular pathogenesis is not fully characterized. The ability to inhibit excessive proliferation and induce the apoptosis of cancer cells are crucial characteristics of anticancer drugs. Pien Tze Huang (PZH) is a widely used traditional Chinese medicine for the treatment of various types of cancer, and has exhibited promising therapeutic effects in clinical trials of HCC. However, the underlying mechanisms for its action are unclear. In the present study, the aim was to explore the effect of PZH on the proliferation and apoptosis of the BEL-7402 HCC cell line, and the associated mechanisms. PZH treatment significantly inhibited BEL-7402 cell viability, confluence and clonogenicity, inducing cell cycle arrest and promoting apoptosis. In addition, PZH treatment suppressed the expression of the pro-proliferative genes cyclin D1 and cyclin-dependent kinase 4, and decreased the expression of the anti-apoptotic gene Bcl-2. PZH treatment also upregulated the expression of a key microRNA (miR), miR-16. The study demonstrated that PZH can effectively inhibit cancer cell proliferation and induce apoptosis in BEL-7402 HCC cells via the upregulation of the tumor suppressor miR-16.

Abstract
MicroRNAs (miRNAs) are small, short endogenous non-coding RNA that act as oncogenes or tumor suppressors, and serve an important role in various human malignant cancers, including colorectal cancer (CRC). Evidence has indicated that miRNAs regulate the expression of various genes associated with human cancer, in particular the miR-34 family. A well-known traditional Chinese formula, Pien Tze Huang (PZH), has a significant clinical effect on CRC. Previous studies have demonstrated that PZH inhibits CRC growth in vitro and in vivo via multiple mechanisms, including the induction of apoptosis, inhibition of cell proliferation and tumor angiogenesis. To further elucidate the molecular mechanisms underlying the antitumor activity of PZH, in the present study its effects on cell proliferation and miRNA expression in human colon carcinoma (HCT)-8 cell lines was examined. It was observed that treatment with PZH inhibited cell viability and upregulated the expression of miR-34c-5p in HCT-8 cells. In addition, transfection with an miR-34c-5p mimic and treatment with PZH inhibited cell survival and arrested the cell cycle between the G0/G1 and S phase in HCT-8 cells. Furthermore, PZH treatment and transfection with miR-34c-5p downregulated the expression of cyclin-dependent kinase 4 and cMyc (a promoter of cell proliferation), and increased the expression of p53, which is a promoter of apoptosis. These results suggest that PZH may suppress proliferation in CRC cells by upregulating the expression of miR-34c-5p, which provides a novel perspective for understanding the mode of action of PZH.

Abstract
The well-known traditional Chinese medicine formula Pien Tze Huang (PZH) has long been used to treat various malignancies, including colorectal cancer (CRC). It was recently reported that PZH possesses the ability to overcome multidrug resistance in CRC cells. In the present study, a 5-fluorouracil (5-FU) resistant human CRC cell line (HCT-8/5-FU) was used to further evaluate the effect of PZH on chemotherapy (chemo)-resistance and investigate the mechanisms through which this occurs. The results identified that PZH significantly reduced the viability and cell density of HCT-8/5-FU cells in a dose- and time-dependent manner (P<0.05). PZH inhibited cell survival, reduced the proportion of cells in S-phase, and suppressed the expression of pro-proliferative proteins cyclin D1 and cyclin-dependent kinase 4. In addition, PZH treatment induced nuclear condensation and fragmentation, activated caspase-9 and -3 and increased the pro-apoptotic Bcl-2-associated X protein/B-cell lymphoma 2 protein ratio. Furthermore, PZH treatment upregulated the expression of microRNA-22 (miR-22) and downregulated the expression of c-Myc (a target gene of miR-22). In conclusion, the findings from the present study suggest that PZH can overcome chemo-resistance in cancer cells, likely through increasing miR-22 expression, and by reversing the imbalance between levels of proliferation and apoptosis.

Abstract
Chemotherapeutic agents, including 5-fluorouracil (5-FU), frequently cause intestinal mucositis as a side effect, leading to life quality reduction in colorectal cancer (CRC) patients and interruption of CRC treatment. Traditional Chinese medicines (TCMs) have recently received attention due to their relatively few adverse effects. Pien Tze Huang (PZH), a well-known TCM formulation first documented to have been prescribed >450 years ago, has been demonstrated to be clinically effective in treating various types of cancer including CRC. Although previous studies by our group reported that PZH possesses a variety of anti-cancer activities via multiple mechanisms, it has remained elusive whether it is able to reduce intestinal mucositis induced by 5-FU. The present study evaluated the effect of PZH on 5-FU-induced intestinal mucositis in CT-26 tumor-bearing xenograft mice and investigated the possible molecular mechanism. The results indicated that administration of PZH effectively alleviated the severity of 5-FU-induced diarrhea and morphological intestinal damages, but had no significant effect on body weight loss. In addition, a terminal deoxynucleotidyl transferase dUTP nick end labeling assay revealed that PZH treatment significantly inhibited cell apoptosis in the intestinal crypt. Furthermore, immunohistochemical staining showed that PZH treatment reduced the protein expression of pro-apoptotic B-cell lymphoma 2 (Bcl-2)-associated X protein but enhanced that of anti-apoptotic Bcl-2 in the intestinal crypt. Taken together, the results of the present study suggested that PZH effectively attenuates 5-FU-induced intestinal mucositis, which is in part associated with its inhibitory effect on cell apoptosis in the intestinal crypt.

Abstract
INTRODUCTION Although gender differences in morbidity and mortality have been measured in patients with moderate to severe burn injury, little attention has been directed at gender effects on health-related quality of life (HRQoL) following burn injury. The current study was therefore conducted to prospectively measure changes in HRQoL for males and females in a sample of burn patients. METHODS A total of 114 adults who received treatment at a statewide burns service for a sustained burns injury participated in this study. Instruments measuring generic health status (Short Form 36 Medical Outcomes Survey version 2), burn-specific HRQoL (Burns Specific Health Scale-Brief), psychological distress (Kessler Psychological Distress Scale) and alcohol use (Alcohol Use Disorders Identification Tool) were prospectively measured at 3, 6 and 12 months post-burn. RESULTS In the 12 months post-injury, female patients showed overall poorer physical (p=0.01) and mental health status (p<0.001), greater psychological distress (p<0.001), and greater difficulty with aspects of burn-specific HRQoL: body image (p<0.001), affect (p<0.001), interpersonal functioning (p=0.005), heat sensitivity (p=0.01) and treatment regime (p=0.01). While significant interaction effects suggested that female patients had more improvement in difficulties with treatment regime (p=0.007), female patients continued to report greater difficulty with multiple aspects of physical and psychosocial health status 12 months post-injury. CONCLUSION Even though demographic variables, injury characteristics and burn care interventions were similar across genders, following burn injury female patients reported greater impairments in generic and burn-specific HRQoL along with psychological morbidity, when compared to male patients. Urgent clinical and research attention utilising an evidence-based research framework, which incorporates the use of larger sample sizes, the use of validated instruments to measure appropriate outcomes, and a commitment to monitoring long-term care, can only improve burn-care.

Abstract
Qingxuan Jiangya Decoction (QXJYD), a traditional Chinese medicine formula prescribed by academician Ke-ji Chen, has been used in China to clinically treat hypertension for decades of years. However, the molecular mechanisms of its action remain largely unknown. In this study, we examined the therapeutic efficacy of QXJYD against elevated systolic blood pressure in the spontaneously hypertensive rat (SHR) model, and investigated the underlying molecular mechanisms. We found that oral administration of QXJYD significantly reduced the elevation of systolic blood pressure in SHR but had no effect on body weight change. Additionally, QXJYD treatment significantly decreased the media thickness and ratio of media thickness/lumen diameter in the carotid arteries of SHR. Moreover, QXJYD remarkably promoted apoptosis of vascular smooth muscle cells and reduced the expression of anti-apoptotic B-cell leukemia/lymphoma 2. Furthermore, QXJYD significantly decreased the plasma Angiotensin II level in SHR. Collectively, our findings suggest that reversing vascular remodeling via inducing VSMC apoptosis could be one of the mechanisms whereby QXJYD treats hypertension.

Abstract
Angiogenesis is an essential process of cancer progression and is regulated by multiple intracellular signaling pathways, including signal transducer and activator of transcription 3 (STAT3) and sonic hedgehog (SHH). Thus, these pathways have become a promising target for anti‑cancer therapeutic strategies. Oleanolic acid (OA) is an active compound present in various herbal medicines, which have been used historically for the clinical treatment of various types of human malignancies, including colorectal cancer (CRC). The present study used a CRC mouse xenograft model and human umbilical vein endothelial cells (HUVECs) to evaluate the effect of OA on tumor angiogenesis and on the activation of the STAT3 and SHH signaling pathways. It was determined that OA treatment significantly inhibited tumor growth and reduced intratumoral microvessel density (MVD) in CRC mice. In addition, OA treatment inhibited the proliferation, migration and tube formation in HUVECs, in a dose and time-dependent manner. Furthermore, OA markedly suppressed the activation of the STAT3 and SHH signaling pathways and inhibited the expression of the pro‑angiogenic vascular endothelial growth factor A and basic fibroblast growth factor, two important target genes of the aforementioned signaling pathways. Therefore it is suggested that inhibition of tumor angiogenesis via the suppression of multiple signaling pathways may be one of the underlying mechanisms by which OA exerts its anti-cancer effect.

Abstract
Non‑alcoholic fatty liver disease (NAFLD) is a widespread health concern, and there is currently insufficient understanding regarding its pathogenesis and treatment. The present study aimed to explore the effects of Artemisia capillaris formula (ACF) on high‑fat diet‑induced hepatic steatosis and fatty acid‑induced intracellular lipid accumulation, by micro (mi)RNA regulation. A total of 72 Sprague‑Dawley rats were divided into six groups (n=12/group). One group was designated as the control group and fed a normal diet, and the remaining five groups were allowed ad libitum access to a high‑fat diet for eight weeks, in order to establish an NAFLD rat model. The rats were subsequently administered polyene phosphatidylcholine (PP; 0.076 g/kg body weight/day), low dose of ACF (0.462 g/kg body weight/day), middle dose of ACF (0.924 g/kg body weight/day) or high dose of ACF (1.848 g/kg body weight/day) intragastrically for four weeks. HepG2 human hepatocellular carcinoma cells were treated with oleic acid and palm acid, followed by treatment with various concentrations of ACF. Serum alanine transaminase (ALT), aspartate aminotransferase (AST), triglycerides (TG), total cholesterol (TC), high‑density lipoprotein cholesterol (HDL‑C), low‑density lipoprotein cholesterol (LDL‑C), and steatotic HepG2 human liver carcinoma cell TC and TG levels were measured. ACF and PP treatments attenuated high‑fat diet‑induced hepatic steatosis and fatty acid‑induced intracellular lipid accumulation. A modified high‑fat diet significantly increased ALT, AST, TG, TC, LDL‑C levels and decreased HDL‑C levels. Treatment with ACF and PP abrogated the increase in liver enzymes and TG, TC and LDL‑C levels, but did not influence HDL‑C levels in a high‑fat diet induced rat model of steotosis. Steatotic HepG2 cells exhibited significantly increased levels of both TG and TC. Treatment with ACF significantly decreased TC and TG levels in vivo, and ACF and PP treatment decreased the expression levels of fatty acid synthase (FASN) and increased miR‑122 in vivo and in vitro. In conclusion, these results suggested that ACF may inhibit hepatic steatosis via miR‑122‑induced downregulation of FASN in vivo and in vitro.

Abstract
Due to drug resistance and unacceptable cytotoxicity of most currently-used cancer chemotherapies, naturally occurring products have gained attention in the field of anticancer treatment. Oleanolic acid (OA) is a natural pentacyclic triterpenoic acid and a principal active compound in many medicinal herbs that have long been used to clinically treat various types of human malignancies. Using a colorectal cancer (CRC) mouse xenograft model and the cell line HT-29, we evaluated the effect of OA on tumor growth in vivo and in vitro, and investigated the underlying molecular mechanisms in the present study. We found that OA significantly inhibited tumor growth in volume and weight in CRC xenograft mice. In addition, OA treatment led to the induction of apoptosis and inhibition of cell proliferation. OA significantly reduced the expression of Bcl-2, Cyclin D1 and CKD4, whereas Bax and p21 expression was profoundly increased after OA treatment. Furthermore, OA significantly suppressed the activation of Akt, p70S6K and MAPK signalings, but promoted p53 pathway activation. Collectively, findings from this study suggest that OA possesses a broad range of anticancer effects via modulation of multiple intracellular targets.

Abstract
Previous studies have demonstrated that Hedyotis diffusa Willd (HDW), a traditional Chinese herbal medicine, exhibits potent anticancer activity in models of colorectal cancer (CRC). Aggressive forms of CRC exhibit resistance to widely used chemotherapeutic drugs, including the antimetabolite, 5-fluorouracil (5-FU); however, less is known with regard to the activity of HDW against 5-FU-resistant cancer. In the present study, the mechanism of action and the potency of ethanol extracts of HDW (EEHDW) were investigated on a multidrug-resistant CRC HCT-8/5-FU cell line. Using an MTT cell proliferation assay, EEHDW treatment was shown to significantly reduce the cell viability of HCT-8/5-FU cells in a dose- and time-dependent manner. Furthermore, EEHDW significantly increased the retention of the ATP-binding cassette (ABC) transporter substrate, rhodamine-123, as compared with the untreated controls. To further investigate the molecular mechanisms targeted by EEHDW in the resistant cells, the expression levels of the ABC drug transporter protein, P-glycoprotein (P-gp), and ABC subfamily G member 2 (ABCG2), were analyzed using reverse-transcription polymerase chain reaction and western blot analysis. The mRNA and protein expression levels of P-gp and ABCG2 were reduced in the HCT-8/5-FU cells following EEHDW treatment, indicating that EEHDW inhibits ABCG2-mediated drug resistance by downregulating the expression of ABCG2 and P-gp. Therefore, the potential application of EEHDW as a chemotherapeutic adjuvant represents a promising alternative approach to the treatment of drug-resistant CRC.

Abstract
One of the most critical cellular signal transduction pathways known to malfunction in colorectal cancer is the interleukin-6/signal transducer and activator of transcription 3 (IL-6/STAT3) pathway. Scutellaria barbata D. Don (SB) is well-known traditional medicine in China that targets STAT3 signaling, and it has long been used to treat various types of cancer; however, the precise mechanism of its antitumor activity remains largely unclear. In order to further elucidate this underlying mechanism, an ethanol extract of SB (EESB) in cancer treatment. The aim of the present study was to evaluate the effects of EESB on the IL-6-inducible STAT3 pathway. We tested the dose-response association between EESB, IL-6-induced proliferaion and apoptosis using an MTT assay, colony formation and flow cytometry analysis in vitro. In addition, caspase-9 and caspase-3 activation was determined using a colorimetric assay, the activity of IL-6-induced STAT3 pathway was evaluated using western blot analysis, and the expression levels of cyclin D1, cyclin-dependent kinase 4, Bcl2 and Bcl2-associated X were determined using reverse transcription-polymerase chain reaction and western blot analysis. In the present study it was found that EESB could significantly inhibit the IL-6-mediated increase in STAT3 phosphorylation levels and transcriptional activity in HT-29 human colon carcinoma cells, resulting in the suppression of cell proliferation and the induction of apoptosis. In addition, treatment with EESB markedly inhibited the IL-6-induced upregulation of cyclin D1 and B-cell lymphoma-2, two key target genes of the STAT3 pathway. These results suggest that treatment with EESB could effectively inhibit the proliferation and promote the apoptosis of human colon carcinoma cells via modulation of the IL-6/STAT3 signaling pathway and its target genes.

Abstract
Malignant tumors are exemplified by excessive proliferation and aggressive migration/invasion contributing to increased mortality of cancer patients. Matrix metalloproteinase 9 (MMP9) expression is positively correlated with lung cancer malignancy. The mechanism underlying an elevated MMP9 expression is not clearly defined. We demonstrate here that the transcriptional modulator megakaryocytic leukemia 1 (MKL1) was activated by hypoxia and transforming growth factor (TGF-β), two prominent pro-malignancy factors, in cultured lung cancer cells. MKL1 levels were also increased in more invasive types of lung cancer in humans. Depletion of MKL1 in lung cancer cells attenuated migration and invasion both in vitro and in vivo. Overexpression of MKL1 potentiated the induction of MMP9 transcription by hypoxia and TGF-β, whereas MKL1 silencing diminished MMP9 expression. Of interest, MKL1 knockdown eliminated histone H3K4 methylation surrounding the MMP9 promoter. Further analyses revealed that MKL1 recruited ASH2, a component of the H3K4 methyltransferase complex, to activate MMP9 transcription. Depletion of ASH2 ameliorated cancer cell migration and invasion in an MMP9-dependent manner. Together our data indicate that MKL1 potentiates lung cancer cell migration and invasion by epigenetically activating MMP9 transcription.

Abstract
Metastasis is the leading cause of cancer-related mortality in almost all types of cancers, including colorectal cancer (CRC). Epithelial-mesenchymal transition (EMT) is a critical process during the metastatic cascade. This process may be a potential target for the diagnosis and treatment of CRC. Pien Tze Huang (PZH), a well-known traditional Chinese formula, has been demonstrated to be clinically effective in treating various types of human malignancies, including CRC. Our published data suggest that PZH can induce apoptosis, as well as inhibit cell proliferation and tumor angiogenesis, thus suppressing CRC growth in vitro and in vivo. We evaluated the therapeutic efficacy of PZH against CRC metastasis using a CRC liver metastasis mouse model to further explore the mechanisms underlying the antitumor action of PZH. MTT, migration, and Matrigel invasion assays were used to assess the effect of PZH on cell viability, migration and invasion. We then established an orthotopic liver metastasis model of colon cancer using microsurgical techniques. Mice were intragastrically administered 234 mg/kg/day dose of either PZH or saline for 14 days. The body and tumor weights of the mice were measured after they were sacrificed. Moreover, we examined the effect of PZH inhibition on liver metastasis. Finally, EMT-related proteins and the TGF-β signaling pathway were assessed using immunohistochemical staining (IHS). The present data revealed that PZH significantly inhibited the migration and invasion of CT-26 cells in a dose-dependent manner, which affirmed the inhibitory effect of PZH on CRC cell metastasis. No significant change was observed between the in vivo primary tumor growth and body weight. However, the control group had five cases of liver metastasis (5/6), whereas one case was found in the PZH group (1/6). Thus, PZH exhibited therapeutic efficacy against CRC metastasis without apparent toxicity. The inhibitory effect of PZH on EMT resulted in an increase in E-cadherin expression, as well as a decrease in N-cadherin expression. In addition, PZH significantly inhibited TGF-β, as well as the phosphorylation of Smad2/3 and Smad4 in the tumor tissues, indicating its suppressive action on TGF-β signaling. These molecular effects ultimately resulted in the inhibition of cancer cell EMT and tumor metastasis.

Abstract
Tumor metastasis, a complex process involving the spread of malignant tumor cells from a primary tumor site to a distant organ, is a major cause of failure of cancer chemotherapy. Epithelial-mesenchymal transition (EMT) is a critical step for the initiation of cancer metastasis. The processes of EMT and metastasis are highly regulated by a double-negative feedback loop consisting of TGF-β1/ZEB pathway and miR-200 family, which therefore has become a promising target for cancer chemotherapy. Pien Tze Huang (PZH), a well-known traditional Chinese formula first prescribed in the Ming Dynasty, has been demonstrated to be clinically effective in the treatment of various types of human malignancy including colorectal cancer (CRC). Our published data proposed that PZH was able to induce apoptosis, inhibit cell proliferation and tumor angiogenesis, leading to the suppression of CRC growth in vitro and in vivo. To further elucidate the mode of action of PZH, in the present study we evaluated its effects on the metastatic capacities of human colorectal carcinoma HCT-8 cells and investigated the underlying molecular mechanisms. We found that PZH significantly inhibited the migration and invasion of HCT-8 cells in a dose-dependent manner. In addition, PZH treatment inhibited the expression of key mediators of TGF-β1 signaling, such as TGF-β1, Smad2/3 and Smad4. Moreover, PZH treatment suppressed the expression of ZEB1 and ZEB2, two critical target genes of TGF-β1 pathway, leading to a decrease in the expression of mesenchymal marker N-cadherin and an increased expression of epithelial marker E-cadherin. Furthermore, PZH treatment upregulated the expression of miR-200a, miR-200b and miR-200c. Collectively, our findings in this study suggest that PZH can inhibit metastasis of colorectal cancer cells via modulating TGF-β1/ZEB/miR-200 signaling network, which might be one of the mechanisms whereby PZH exerts its anticancer function.

Abstract
Background The development of hepatic cancer is tightly regulated by multiple intracellular signaling pathways. Therefore, most currently-used anti-tumor agents, which typically target single intracellular pathway, might not always be therapeutically effective. Additionally, long-term use of these agents probably generates drug resistance and unacceptable adverse effects. These problems increase the necessity for the development of new chemotherapeutic approaches. Nitidine chloride (NC), a natural benzophenanthridine alkaloid, has been shown to inhibit cancer growth via induction of cell apoptosis and suppression of cancer angiogenesis. But the precise mechanisms of its tumorcidal activity are not well understood. Methods To further elucidate the precise mechanisms of its anti-tumor activity, using a hepatic cancer mouse xenograft model, the human hepatic cancer cell lines (HepG2, HCCLM3, Huh7), and umbilical vein endothelial cells (HUVEC), here we evaluate the effect of NC on tumor growth in vivo and in vitro and investigated the underlying molecular mechanisms. Results We found that NC treatment resulted in significant decrease in tumor volume and tumor weight respectively, but didn’t affect body weight changes. Additionally, NC treatment dose- and time-dependently reduced the cell viability of all three hepatic cell lines. Moreover, NC suppressed the activation of STAT3, ERK and SHH pathways; and altered the expression of critical target genes including Bcl-2, Bax, Cyclin D1, CDK4, VEGF-A and VEGFR2. These molecular effects resulted in the promotion of apoptosis, inhibition of cell proliferation and tumor angiogenesis. Conclusions Our findings suggest that NC possesses a broad range of anti-cancer activities due to its ability to affect multiple intracellular targets, suggesting that NC could be a novel multi-potent therapeutic agent for the treatment of hepatic cancer and other cancers.

Abstract
Cisplatin (cis-diaminedichloroplatinum-II) is an extensively used chemotherapeutic agent, and one of its most adverse effects is ototoxicity. A number of studies have demonstrated that these effects are related to oxidative stress and DNA damage. However, the precise mechanism underlying cisplatin-associated ototoxicity is still unclear. The cofactor nicotinamide adenine dinucleotide (NAD(+)) has emerged as a key regulator of cellular energy metabolism and homeostasis. Here, we demonstrate for the first time that, in cisplatin-mediated ototoxicity, the levels and activities of SIRT1 are suppressed by the reduction of intracellular NAD(+) levels. We provide evidence that the decrease in SIRT1 activity and expression facilitated by increasing poly(ADP-ribose) transferase (PARP)-1 activation and microRNA-34a through p53 activation aggravates cisplatin-mediated ototoxicity. Moreover, we show that the induction of cellular NAD(+) levels using β-lapachone (β-Lap), whose intracellular target is NQO1, prevents the toxic effects of cisplatin through the regulation of PARP-1 and SIRT1 activity. These results suggest that direct modulation of cellular NAD(+) levels by pharmacological agents could be a promising therapeutic approach for protection from cisplatin-induced ototoxicity.

Abstract
Scutellaria barbata D. Don (SB) has long been used as a major component in numerous Chinese medical formulas to clinically treat various types of cancer. Previously, we reported that the extracts of SB were able to suppress colon cancer growth in vivo and in vitro, possibly by inducing cancer cell apoptosis and inhibiting cell proliferation and tumor angiogenesis. However, the anticancer mechanisms of its bioactive ingredients remain largely unclear. In the present study, using three human colon cancer cell lines SW620, HT-29 and HCT-8, the antitumor effect of different solvent fractions of SB were evaluated and the potential underlying molecular mechanisms were investigated. Using an 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, it was revealed that the chloroform fraction of SB (ECSB) exhibited the most potent inhibitory effect on the growth of all three colon cancer cell lines and SW620 cells exhibited the most sensitive response to ECSB treatment (IC50=65 µg/ml). In addition, by performing fluorescence-activated cell sorting, transmission electron microscopy and colony formation assays, it was observed that ECSB significantly induced apoptosis and inhibited proliferation in SW620 cells in a dose-dependent manner. Furthermore, ECSB treatment resulted in the upregulation of the pro-apoptotic Bax/Bcl-2 ratio and a decrease in the expression of the pro-proliferative cyclin D1 and cyclin-dependent kinase 4. The results from the present study may provide a scientific foundation for the development of novel anticancer agents from the bioactive ingredients in the ECSB.

Abstract
The pathogenic mechanisms underlying cancer development are complex and heterogeneous, involving multiple cellular signaling transduction pathways that usually function redundantly. In addition, crosstalk between these pathways generates a complicated and robust signaling network that is regulated by compensatory mechanisms. Given the complexity of cancer pathogenesis and progression, many of the currently used antitumor agents, which typically target a single intracellular pathway, might not always be effective on complex tumor systems. Moreover, long-term use of these agents often generates drug resistance and toxicity against normal cells. Therefore, the development of novel anticancer chemotherapies is urgently needed.Scutellaria barbataD Don (SB) is a medicinal herb that has long been used in China to treat various types of cancer. We previously reported that the ethanol extract of SB (EESB) is able to induce colon cancer cell apoptosis, inhibit cell proliferation and tumor angiogenesis via modulation of several pathways, including Hedgehog, Akt, and p53. To further elucidate the precise mechanisms of SB's antitumor activity, using a colorectal cancer (CRC) mouse xenograft model in the present study, we evaluated the therapeutic efficacy and molecular mechanisms of EESB against tumor growth. We found that EESB reduced tumor volume and tumor weight but had no effect on body weight gain in CRC mice, demonstrating that EESB could inhibit colon cancer growth in vivo without apparent adverse effect. In addition, EESB treatment could significantly suppress the activation of several CRC-related pathways, including STAT3, Erk, and p38 signalings in tumor tissues, and alter the expression of multiple critical target genes such as Bcl-2, Bax, Cyclin D1, CDK4, and p21. These molecular effects lead to the induction of cancer cell apoptosis and inhibition of cell proliferation. Our findings demonstrate that SB possesses a broad range of antitumor activities because of its ability to affect multiple intracellular targets.

Abstract
Accumulating evidence suggests that a small population of cells termed cancer stem cells (CSCs) are crucial in tumor development and drug resistance, leading to cancer relapse and metastasis and eventually the failure of clinical cancer treatment. Therefore, targeting CSCs is a promising approach for anticancer therapies. Due to the drug resistance and adverse effects of currently used chemotherapies, traditional Chinese medicines (TCM) have recently received attention due to the relatively few side-effects. Thus, they have been used as important alternative remedies for various diseases, including cancer. Pien Tze Huang (PZH), a well-known TCM formula that was first prescribed more than 450 years ago in the Ming Dynasty, has been used in China and Southeast Asia for centuries as a folk remedy for various types of cancer. Previously, it was reported that PZH inhibits colon cancer growth via the promotion of cancer cell apoptosis and inhibition of cell proliferation and tumor angiogenesis, which is probably mediated by its regulatory effect on multiple intracellular signaling pathways. To elucidate the mechanism of the tumoricidal activity of PZH, the aim of the present study was to investigate the effect of PZH on CSCs that were isolated as the side population (SP) from the HT-29 colorectal cancer cell line. The results demonstrated that PZH significantly and dose-dependently reduced the percentage of the colorectal cancer stem-like SP cells, decreased the viability and sphere-forming capacity of HT-29 SP cells, indicating that PZH is potent in suppressing the growth of colorectal cancer stem cells. Moreover, PZH treatment in HT-29 SP cells markedly inhibited the mRNA levels of ABCB1 and ABCG2, which are members of the ABC transporter superfamily, thereby contributing to the SP phenotype and multi-drug resistance. Findings of the present study suggest that inhibiting the growth of CSCs is a potential mechanism by which PZH can be used in cancer treatment.

Abstract
The development of colorectal cancer (CRC) is strongly correlated with the aberrant activation of multiple intracellular signaling transduction cascades including STAT3, ERK, JNK and p38 pathways which usually function redundantly. In addition, crosstalk between these pathways forms a complicated signaling network that is regulated by compensatory mechanisms. Therefore, most of the currently used and single-target-based antitumor agents might not always be therapeutically effective. Moreover, long-term use of these agents often generates drug resistance. These problems highlight the urgent need for the development of novel anticancer chemotherapies. Ursolic acid (UA) is a major active compound present in many medicinal herbs that have long been used for the clinical treatment of CRC. Although previous studies have demonstrated an antitumor effect for UA, the precise mechanisms of its tumoricidal activity are not well understood. In the present study, using CRC mouse xenograft model and the HT-29 human colon carcinoma cell line, we evaluated the efficacy of UA against tumor growth in vivo and in vitro and investigated the underlying molecular mechanisms. We found that UA inhibits cancer growth without apparent toxicity. Furthermore, UA significantly suppresses the activation of several CRC-related signaling pathways and alters the expression of critical target genes. These molecular effects lead to the induction of apoptosis and inhibition of cellular proliferation. These data demonstrate that UA possesses a broad range of anticancer activities due to its ability to affect multiple intracellular targets, suggesting that UA could be a novel multipotent therapeutic agent for cancer treatment.
