Tumor necrosis factor-related apoptosis inducing ligand (TRAIL/APO-2L) activates nuclear factor κB (NFκB). This activation is regulated by the recruitment of an adaptor protein Fas associating death domain (FADD) to TRAIL death receptors, death receptor 4 (DR4, TRAIL-R1) and death receptor 5 (DR5 TRAIL-R2). This leads to recruitment of caspase 8 and(More)
Accumulating evidence supports an important role for the hepatitis B virus x protein (HBx) in the pathogenesis of hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC), but the underlying mechanisms are not entirely clear. Here, we identified a novel long noncoding RNA (lncRNA) DBH-AS1 involved in the HBx-mediated hepatocarcinogenesis. The levels(More)
The apoptosis effector Bid regulates cell death at the level of mitochondrial cytochrome c efflux. Bid consists of 8 α-helices (designated H1 through H8, respectively) and is a soluble cytosolic protein in its native state. Proteolysis of the N-terminus (encompassing H1 and H2) of Bid yields activated “tBid” (truncated Bid), which translocates to the(More)
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors with an increasing incidence worldwide. Apolipoprotein M (apoM) is a novel apolipoprotein that is mainly expressed in liver and kidney tissues. However, the anti-tumor properties of apoM remain largely unknown. We evaluated the anti-tumor activities and mechanisms of apoM in HCC both(More)
AIM miR-548p is a recently identified and poorly characterized miRNA. However, its role of miR-548p in tumorigenesis and progression remains poorly understood. Here, we aimed to investigate the biofunction of miR-548p in hepatocellular carcinogenesis. METHODS The expression levels of miR-548p were detected by quantitative reverse transcription polymerase(More)
Hepatocellular carcinoma (HCC) is the fifth most common malignancy worldwide. PHD finger protein 19 (PHF19) encodes a member of the polycomb group (PcG) of proteins that functions by maintaining the repressive transcriptional states of many developmental regulatory genes. In addition, it has been shown that miR-195 plays an important role in the molecular(More)
Hepatocellular carcinoma (HCC) is a highly aggressive, solid malignancy that has a poor prognosis. Long non-coding RNAs (lncRNAs) have been found to be dysregulated in various cancers, including HCC. However, the molecular mechanism involving lncRNAs in HCC remains largely unknown. In this study, lncRNAs differentially expressed between HCC and(More)
Exosomes are cell-derived vesicles and are abundant in biological fluids; they contain RNA molecules which may serve as potential diagnostic biomarkers in 'precision medicine'. To promote the clinical application of exosomal RNA (exoRNA), many isolation methods must be compared and validated. Exosomes in cell culture medium (CCM) and serum may be isolated(More)
OBJECTIVE To investigate the effect of simulated microgravity on erythroid differentiation of K562 cells and explore the possible mechanism. METHODS The fourth generation rotating cell culture system was used to generate the simulated microgravity environment. Benzidine staining was used to evaluate the cell inhibition rate, and real-time quantitative PCR(More)
