BACKGROUND Chlorpromazine (CPZ), a commonly used antipsychotic drug, was found to play a neuroprotective role in various models of toxicity. However, whether CPZ has the potential to affect brain apoptosis in vivo is still unknown. The purpose of this study was to investigate the potential effect of CPZ on the apoptosis induced by exogenous stimuli. (More)
Overexpression of metadherin (MTDH) has been reported in many solid tumors and implicated in chemoresistance. This study aimed to examine MTDH expression in cervical cancer tissues and explore its role in chemoresistance of cervical cancer. MTDH expression in cervical cancer biopsies and several cervical cancer cell lines was detected by immunoblotting and(More)
MiR-122 is a liver-specific miRNA. Recent studies demonstrated that the interferon (IFN) therapy efficacy is poor in the hepatitis C virus (HCV)-infected patients with lower miR-122 abundance in the livers. The hepatocarcinoma patients also have low miR-122 levels in their livers. We previously found that the IFN expression was reduced when miR-122 was(More)
Type I interferon (IFN) is believed to play significant roles in limiting tumor growth. It has been revealed that the induction of endogenous IFN expression is one of the key mechanisms for successful IFN therapy. However, recent studies have shown that the efficacy of type I IFN therapy has limitations in the clinical treatment of certain tumors, including(More)
Using RNAhybrid software we found the predicted binding of complementary sequences between miR-122 and viral mRNAs, may be important for the antiviral effect of miR-122 on Borna disease virus (BDV). A moderate expression of miR-122 was identified in human oligodendroglial cells (OL), but with a much lower level of miR-122 in BDV persistent infection(More)
It has been reported that the Borna disease virus (BDV) encoded phosphoprotein (P protein) can inhibit the activity of Traf family member-associated NF-kappaB activator (TANK)-binding kinase 1 (TBK-1), thus preventing the induction of type I interferon (IFN). However, the effects of microRNA on the regulation of BDV infection and the host's immune response(More)
The expression of type I interferon (IFN) is one of the most potent innate defences against viral infection in higher vertebrates. Borna disease virus (BDV) establishes persistent, noncytolytic infections in animals and in cultured cells. Early studies have shown that the BDV phosphoprotein can inhibit the activation of type I IFN through the TBK1-IRF3(More)
Viruses often have strategies for preventing host cell apoptosis, which antagonizes viral replication. Borna disease virus (BDV) is a neurotropic RNA virus that establishes a non-cytolytic persistent infection. Although BDV suppresses type I Interferon (IFN) through (TANK)-binding kinase 1 (TBK-1) associated BDV P protein, it is still unclear how BDV can(More)
Human Papillomavirus (HPV) 16 infection is considered as one of the significant causes of human cervical cancer. The expression of the viral oncogenes like E6 and E7 play an important role in the development of the cancer. MiR-122 has been reported to exhibit a strong relationship with hepatitis viruses and take part in several tumor development, while the(More)
MicroRNA-122 (miR-122) is involved in the pathogenesis of several liver diseases, including chronic hepatitis B infection and hepatocellular carcinoma. This study aimed to explore the potential role of miR-122 in the interferon (IFN)-mediated suppression of hepatitis B virus (HBV) in hepatocytes. We found that elevated expression of suppressor of cytokine(More)
