Breast cancer is the leading cause of cancer death in women world wide which is closely related to metastasis. Recent studies argue that breast cancer cells that have undergone epithelial-to-mesenchymal transition (EMT) acquire aggressive malignant properties, but the molecular mechanisms underlying this transition are poorly understood. In this study, we(More)
Hepatocellular carcinoma (HCC)-associated macrophages accelerate tumor progression via growth factor release. Therefore, tumor-associated macrophages (TAMs)-initiated signaling cascades are potential therapeutic targets. To better understand anticancer effects of systemic HCC therapy, we studied sorafenib's effect on macrophage function, focusing on(More)
BACKGROUND Hepatocellular carcinoma (HCC) is the most common liver malignancy worldwide. However, present studies of its multiple gene interaction and cellular pathways still could not explain the initiation and development of HCC perfectly. To find the key genes and miRNAs as well as their potential molecular mechanisms in HCC, microarray data GSE22058,(More)
Objective To isolate and purify Kupffer cells (KCs) from BALB/c mice by an efficient method of low-speed centrifugation and rapid adherence. Methods The mouse liver tissue was perfused in situ and digested with 0.5 g/L collagenase type IV in vitro by water bath. Then, through the low-speed centrifugation, KCs were separated from the mixed hepatocytes, and(More)
IL-37 has been characterized as a fundamental inhibitor of innate immunity and a tumor suppressor in several cancers. However, the molecular mechanism of IL-37 in hepatocellular carcinoma (HCC) is largely unclear. In this study we found IL-37 expression was down-regulated in human HCC tissues and cell lines, and was negatively correlated with tumor size,(More)
Objective To evaluate the impact of miR-148a on hepatic ischemia/reperfusion (I/R) injury via inhibiting Ca(2+)/calmodulin-dependent protein kinase IIα (CaMKIIα), and analyze the potential mechanism. Methods Liver I/R model was built in mice. Expression of CaMKIIα was detected in the hepatic tissues by Western blotting. The mRNA levels of miR-148a, CaMKIIα,(More)
Objective To investigate the protective effect of fisetin (FIS) against hypoxia/reoxygenation (H/R) injury in rat hepatocytes and its mechanism. Methods H/R injury model of BRL-3A cells was established and the cells were pretreated with FIS. Survival rate was detected by CCK-8 assay. Cell apoptosis was measured by flow cytometry. The levels of ALT and AST(More)
Objective To study the effect of microRNA-21 (miR-21) on hypoxia/reoxygenation (H/R)-treated primary hepatocytes from C57BL/6J mice and analyze its possible molecular mechanism. Methods The H/R model of primary hepatocytes was established and the expression of miR-21 was detected by the quantitative real-time PCR. Western blotting was used to detect protein(More)
