    ABSTRACT: Chemoresistance blocks the efficient treatment of epithelial ovarian cancer, which is the most lethal of all gynecological cancers. Cancer stem cells are believed to be at least partially responsible for the development of chemoresistance. In this study, the effect of cisplatin (CDP) on the enrichment and proliferation of cancer stem-like cells (CSLCs) was investigated, and the underlying mechanisms of action were elucidated. An in vitro anchor-free system was employed to enrich CSLCs from the SKOV3 human epithelial ovarian cancer cell line. Our results showed that treatment with low concentrations of CDP resulted in better-enriched CSLCs, with higher proliferative activities. Low dose of CDP was found to induce the expression of chemokine (C-X-C motif) receptor 4 (CXCR4), which is an important stemness marker in cancer stem cells as well as a promising therapeutic target for ovarian cancer treatment. Results also showed that overexpressed CXCR4 generated chemoresistance. Based on these results, it may be concluded that, at low concentrations, CDP itself contributes to the development of drug resistance. This finding provides novel insight into the mechanisms underlying chemoresistance and has significant therapeutic implications for epithelial ovarian cancer treatment.

    ABSTRACT: MicroRNAs are ∼22 nucleotide RNAs processed from RNA hairpin structures that play important roles in regulating protein expression level via binding to mRNA, either suppressing its translation or speeding up its degradation. In humans, they regulate most protein-coding genes, including genes important in cancer and other diseases. In this study, the expression of microRNA-140 (miR-140) was demonstrated to be significantly suppressed in pancreatic duct adenocarcinoma specimens and cell lines, compared with their adjacent normal tissues. With the help of bioinformatics analysis, inhibitor of apoptosis-stimulating protein of p53 (iASPP) was identified to be a direct target of miR-140, and luciferase reporter experiment confirmed this discovery. Overexpression of miR-140 decreases the protein expressions of iASPP, ΔNp63, MMP2, and MMP9. Growth and invasion of PANC-1 cells were attenuated by overexpression of miR-140 in vitro. The suppressive effect of miR-140 on PANC-1 cell line could be partly balanced out by manual overexpression of iASPP. Above all, these findings provided insights into the functional mechanism of miR-140, suggested that the miR-140/iASPP axis may interfere with the proliferative and invasive property of pancreatic duct adenocarcinoma cells, and indicated that miR-140 could be a potential therapeutic target for pancreatic duct adenocarcinoma.

    ABSTRACT: BmK I, purified from the venom of scorpion Buthus martensi Karsch (BmK), is a receptor site-3-specific modulator of voltage-gated sodium channels (VGSCs) and can induce pain-related behaviors in rats. The tetrodotoxin-resistant (TTX-R) sodium channel Nav1.8 contributes to most of the sodium current underlying the action potential upstroke in dorsal root ganglia (DRG) neurons and may serve as a critical ion channel targeted by BmK I. Herein, using electrophysiological, molecular, and behavioral approaches, we investigated whether the aberrant expression of Nav1.8 in DRG contributes to generation of pain induced by BmK I. The expression of Nav1.8 was found to be significantly increased at both mRNA and protein levels following intraplantar injection of BmK I in rats. In addition, the current density of TTX-R Nav1.8 sodium channel is significantly increased and the gating kinetics of Nav1.8 is also altered in DRG neurons from BmK I-treated rats. Furthermore, spontaneous pain and mechanical allodynia, but not thermal hyperalgesia induced by BmK I, are significantly alleviated through either blockade of the Nav1.8 sodium channel by its selective blocker A-803467 or knockdown of the Nav1.8 expression in DRG by antisense oligodeoxynucleotide (AS-ODN) targeting Nav1.8 in rats. Finally, BmK I was shown to induce enhanced pain behaviors in complete freund's adjuvant (CFA)-inflamed rats, which was partly due to the over-expression of Nav1.8 in DRG. Our results suggest that functional up-regulation of Nav1.8 channel on DRG neurons contributes to the development of BmK I-induced pain in rats.

    ABSTRACT: Pancreatic ductal adenocarcinoma (PDAC) is one of the most deadly human malignant diseases and the sixth leading cause of cancer-related deaths in China. Gemcitabine is the only first-line chemotherapeutic agent used for the palliative treatment of patients with PDAC, but chemo-resistance limits their efficacy. Here, we showed that miR-125a was up-regulated in chemo-resistant SW1990GZ cells when compared with SW1990 cells. Over-expression of miR-125a increased the chemo-resistance to gemcitabine in SW1990 cells, while down-regulation of miR-125a in SW1990GZ cells increased chemo-sensitivity to gemcitabine. By using bioinformatics analysis tool (Targetscan), the 3' untranslated region (3'UTR) of A20 gene was found to be a target of miR-125a. Luciferase reporter assay further confirmed that A20 3'UTR is a direct target of miR-125a. Over-expression of A20 in SW1990 cells increased chemo-sensitivity to gemcitabine, while knockdown of A20 in SW1990 cells promoted the chemo-resistance to gemcitabine. Finally, the expression level of miR-125a in pancreatic cancer tissues from chemo-sensitive patients was significantly lower than that from chemo-resistant patients, and was inversely correlated with the A20 mRNA levels. In conclusion, our results suggest that miR-125a promotes chemo-resistance to gemcitabine in pancreatic cells through targeting A20, which may provide novel therapeutic targets or molecular biomarkers for cancer therapy and improve tumor diagnosis or predictions of therapeutic responses.

    ABSTRACT: The prostate transmembrane protein, androgen-induced 1 (PMEPA1) has been previously shown to promote solid malignancies in a variety of cancers, but the role and mechanisms of PMEPA1 in breast cancer has not been fully addressed. Here, we found that PMEPA1 was upregulated in breast cancer cell lines as well as in a set of clinical invasive breast ductal carcinomas. Interestingly, depletion of PMEPA1 decreased breast cancer stem cell (CSC)-enriched populations, while ectopic overexpression of PMEPA1 increased breast CSC-enriched populations. Furthermore, transforming growth factor-β (TGF-β) treatment was also found to upregulate PMEPA1 expression and the CSC-enriched populations in triple-negative breast cancer cell lines. TGF-β-induced PMEPA1 expression partially contributed to TGF-β-induced breast CSC maintenance. These findings suggest that TGF-β-PMEPA1 axis might provide new diagnosis and therapeutic targets for breast cancer treatment.

    ABSTRACT: In the present study, paclitaxel (PTX) were encapsulated with polyethylene glycol (PEG)-polylactide (PLA)/D-α tocopheryl polyethylene glycol 1000 succinate (TPGS) (PEG-PLA/TPGS) and the enhanced anti-tumor activity of this PTX mixed micelles (PTX-MM) was evaluated in lung cancer cells. The PTX-MM prepared by a solvent evaporation method was demonstrated to have high drug-loading efficiency (23.2%), high encapsulation efficiency (76.4%), and small size (59 nm). In vitro release assay showed the slow release behavior of PTX-MM, suggesting the good stability of the PTX-MM essential for long circulation time. In vitro kinetics assay demonstrated that PTX-MM could promote absorption and increase relative bioavailability. The anti-cancer efficiency of PTX-MM was also examined by both in vitro and in vivo studies. PTX-MM exhibits obvious cytotoxicity against lung cancer cells with much lower IC50 value when compared with commercial formulated PTX or PTX + TPGS. The xenograft tumor model studies on nude mice indicated that PTX-MM inhibits tumor growth more effectively than other formulations. It was also found that most of mixed micelles were integral in tumor site to exhibit anti-cancer activity. Our results suggested that the use of PTX-MM as an anti-cancer drug may be an effective approach to treat lung cancer.

    ABSTRACT: The pleiotropic second messenger adenosine 3′,5′-cyclic monophosphate (cAMP) regulates a myriad of biological processes under both physiological and pathophysiological conditions. Exchange protein directly activated by cAMP 1 (EPAC1) mediates the intracellular functions of cAMP by acting as a guanine nucleotide exchange factor for the Ras-like Rap small GTPases. Recent studies suggest that EPAC1 plays important roles in immunomodulation, cancer cell migration/metastasis, and metabolism. These results, coupled with the successful development of EPAC-specific small molecule inhibitors, identify EPAC1 as a promising therapeutic target for cancer treatments.

    ABSTRACT: Eukaryotic elongation factor 1A (eEF1A) is a multifunctional protein involved in bundling actin, severing microtubule, activating the phosphoinositol-4 kinase, and recruiting aminoacyl-tRNAs to ribosomes during protein biosynthesis. Although evidence has shown the presence of the isoform eEF1A1 oligomers, the substantial mechanism of the self-association remains unclear. Herein, we found that human eEF1A1 could spontaneously form oligomers. Specifically, mutagenesis screen on cysteine residues demonstrated that Cys234 was essential for eEF1A1 oligomerization. In addition, we also found that hydrogen peroxide treatment could induce the formation of eEF1A oligomers in cells. By cysteine replacement, eEF1A2 isoform displayed the ability to oligomerize in cells under the oxidative environment. In summary, in this study we characterized eEF1A1 oligomerization and demonstrated that specific cysteine residues are required for this oligomerization activity.

    ABSTRACT: The unfolded protein response (UPR) is a cascade of events that helps restoring cellular homeostasis under stressful conditions. It is activated when there is an imbalance in the protein load and protein folding capacity of the endoplasmic reticulum (ER) as a result of an increase in the naïve, unfolded, or misfolded protein content of the cell. Dengue virus (DENV) utilizes the host machinery to synthesize viral proteins and replicates in the cell. During DENV infection, up-regulation of viral proteins increases the protein pool of the cell, resulting in the induction of UPR pathway. In this study, we have tried to understand the consequence of UPR induction during DENV infection in human monocytic cells. To fulfill this objective, we have used VER-155008 (VER), a known inhibitor of the 78 kDa glucose-regulated protein (GRP78), which is the master regulator of the UPR pathway. After VER treatment, cells were infected with DENV, and the induction of the UPR elements and their downstream activation was studied by western blotting and RT-PCR analysis. Interestingly, inhibition of GRP78 via VER treatment led to the decreased expression of DENV envelope protein through the activation of the UPR elements, protein kinase-like ER resident kinase, activating transcription factor 6, and inositol-requiring enzyme 1 (IRE1), and then led to the activation of innate immune factors such as double-stranded RNA-activated protein kinase (PKR), interferon regulated factor 3 (IRF3), nuclear factor-κB (NF-κB) and interleukin 1β (IL-1β). This strategy may be used to decrease viral infection transiently. Thus UPR elements could be important therapeutic targets for decreasing DENV multiplication.

    ABSTRACT: Lysine (K)-specific demethylase 4B (KDM4B) is a histone H3K9 demethylase and is reported to activate gene transcription through regulation of chromatin structures. Previous research has revealed that KDM4B plays special regulatory roles in colorectal, prostate and gastric cancers. However, its physiological role in pancreatic cancer remains largely unknown. In the present study, it is demonstrated KDM4B plays a crucial in epithelial-mesenchymal transition (EMT) in pancreatic cancer. siRNA mediated silencing of KDM4B inhibits cell migration, invasion and EMT. Moreover, KDM4B was demonstrated to epigenetically regulate the expression of ZEB1 in the TGF-β-induced EMT process. In tumor tissues of pancreatic cancer patient, the protein level of KDM4B was positively correlated with ZEB1. In conclusion, our results suggested that KDM4B is a key mediator in EMT process, and may serve as an important prognostic marker and therapeutic target for the metastatic progression of human pancreatic cancer.

    ABSTRACT: Epigenetic regulation of gene expression is a dynamic and reversible process with DNA methylation, histone modifications, and chromatin remodeling. Recently, groundbreaking studies have demonstrated the importance of DNA and chromatin regulatory proteins from different aspects, including stem cell, development, and tumor genesis. Abnormal epigenetic regulation is frequently associated with diseases and drugs targeting DNA methylation and histone acetylation have been approved for cancer therapy. Although the network of epigenetic regulation is more complex than people expect, new potential druggable chromatin-associated proteins are being discovered and tested for clinical application. Here we review the key proteins that mediate epigenetic regulations through DNA methylation, the acetylation and methylation of histones, and the reader proteins that bind to modified histones. We also discuss cancer associations and recent progress of pharmacological development of these proteins.

    ABSTRACT: We have previously demonstrated that geniposide attenuates the production of Aβ1–42 both in vitro and in vivo via enhancing leptin receptor signaling. But the role played by geniposide in the phosphorylation of tau and its underlying molecular mechanisms remain unclear. In this study, we investigated the effect of geniposide on the phosphorylation of tau and the role of leptin signaling in this process. Our data suggested that, accompanied by the up-regulation of leptin receptor expression, geniposide significantly decreased the phosphorylation of tau in rat primary cultured cortical neurons and in APP/PS1 transgenic mice, and this geniposide-induced decrease of tau phosphorylation could be prevented by leptin antagonist (LA). Furthermore, LA also prevented the phosphorylation of Akt at Ser-473 site and GSK-3β at Ser-9 site induced by geniposide. All these results indicate that geniposide may regulate tau phosphorylation through leptin signaling, and geniposide may be a promising therapeutic compound for the treatment of Alzheimer's disease in the future.
