Abstract Background: Phototherapies based on sunlight, infrared, ultraviolet, visible, and laser-based treatments present advantages like high curative effects, small invasion, and negligible adverse reactions in cancer treatment. We aimed to explore the potential therapeutic effects of blue light emitting diode (LED) in human hepatoma cells and decipher the underlying cellular and molecular mechanisms. Methods: Wound healing and transwell assays were employed to probe the inhibition of the invasion and migration of hepatocellular carcinoma cells in the presence of blue LED. The sphere-forming test was used to evaluate the effect of LED blue light irradiation on cancer… More > Graphic Abstract

Abstract Sorafenib, a multityrosine kinase inhibitor, is a standard treatment for advanced hepatocellular carcinoma (HCC), but the clinical response to sorafenib is seriously limited by drug resistance. Programmed death ligand-1 (PD-L1) is one of the most important inhibitory molecules involved in tumor immune evasion. Recently, it has been reported that PD-L1 could play crucial roles in drug resistance of many kinds of cancers. However, the expression, function, and regulation of PD-L1 in sorafenib-resistant hepatoma cells remain unclear. In this study, we reported that PD-L1 was overexpressed in sorafenib-resistant hepatoma cells, and shRNA-mediated PD-L1 depletion attenuated drug… More >

Abstract Hepatocellular carcinoma (HCC) ranks the sixth place of most common cancers. Meanwhile, it is the tertiary mortality cause of cancer. There is no effective therapeutic method to prevent and treat the liver cancer. Sinomenine is a kind of Chinese traditional medicine herbal, it is reported that it can inhibit the viability of several cancer cells. The study is to explore whether sinomenine is also able to inhibit the cell viability of HCC and its potential mechanism. The IC50 of sinomenine in BEL-7402 cells was 5.351 mmol/L, and the IC50 of sinomenine in SMMC-7721 cells was… More >

Abstract Hepatocellular carcinoma (HCC) is one of the most prevalent and lethal malignancies worldwide. Increased matrix stiffness of extracellular matrix (ECM) is commonly associated with HCC. During tumour formation and expansion, increasing glucose metabolism is necessary for unrestricted growth of tumour cells. Yet, the correlation between matrix stiffness and glucose metabolism in the development of HCC remains unknown. In this study, we aim to investigate the effect of matrix stiffness on glucose metabolism and migration of MHCC97L and HepG2 hepatoma cells, and explore the mechanotransduction involved in this process. Polyacrylamide hydrogels with stiffness gradients of 6,… More >

Abstract Dysregulated microRNA (miRNA) expression is involved in the occurrence and development of colorectal cancer (CRC) through the regulation of various important physiological events. Hence, miRNAs may be used as effective targets for CRC treatment; however, this hypothesis warrants further investigation. miRNA-511 (miR-511) plays vital roles in the progression of different tumor types. However, the expression, exact role, and the mechanisms underlying the regulation of colorectal carcinogenesis and progression by miR-511 remain poorly understood. This study presents that miR-511 expression was decreased in CRC tissues and cell lines compared with that in adjacent nonneoplastic tissues and More >

Abstract Previous studies have shown that 5,2',4'-trihydroxy-6,7,5'-trimethoxyflavone (TTF1) is the primary anticancer constituent of the traditional Chinese medicinal plant Sorbaria sorbifolia (SS), which has been applied to treat cancer in China. In this study, we investigated the in vitro and in vivo antitumor effects and biological mechanisms of small-molecule TTF1 nanoparticles (TTF1-NPs). The effects of TTF1-NPs on cell growth and apoptosis were investigated using human hepatoma cells. The molecular changes associated with the effects of TTF1-NPs were analyzed by immunocytochemistry and Western blot analysis. The in vivo effect of TTF1-NPs was investigated using the HepG2 tumor xenograft More >

Abstract Expression of adhesion molecules may play an important role in the interaction of tumor cells with vascular endothelial cells during tumor invasion and metastasis. In this study, the adhesive force of human hepatoma HepG2 cells to human umbilical vein endothelial cells (HUVECs) was investigated using a micropipette aspiration technique. Expression of an adhesion molecule, E-selectin, was also observed by immunofluorescence microscopy. In particular, the adhesive force after stimulation of HUVECs with recombinant human interleukin-1β (rhIL-1β) was examined. The results demonstrated that the adhesive force of HepG2 cells to stimulated HUVECs is significantly higher than that More >
