A transcriptome profile in hepatocellular carcinomas based on integrated analysis of microarray studies

Background Despite new treatment options for hepatocellular carcinomas (HCC) recently, 5-year survival remains poor, ranging from 50 to 70%, which may attribute to the lack of early diagnostic biomarkers. Thus, developing new biomarkers for early diagnosis of HCC, is extremely urgent, aiming to decrease HCC-related deaths. Methods In the study, we conducted a comprehensive...

Neuromechanism Study of Insect–Machine Interface: Flight Control by Neural Electrical Stimulation

The insect–machine interface (IMI) is a novel approach developed for man-made air vehicles, which directly controls insect flight by either neuromuscular or neural stimulation. In our previous study of IMI, we induced flight initiation and cessation reproducibly in restrained honeybees (Apis mellifera L.) via electrical stimulation of the bilateral optic lobes. To explore the...

Gene silencing of heparanase results in suppression of invasion and migration of hepatoma cells

Background This study investigated the effect of transcriptional gene silencing (TGS) of the heparanase gene on hepatoma SMCC-7721 cells. Methods SiRNAs targeting the promoter region and coding region of the heparanase gene were designed and synthesized. Then the siRNAs were transfected into hepatoma SMCC-7721 cells by nuclear transfection or cytoplasmic transfection. The...

Effects of the epigenetic drug MS-275 on the release and function of exosome-related immune molecules in hepatocellular carcinoma cells

Background Tumor-derived exosomes have been viewed as a source of tumor antigens that can be used to induce anti-tumor immune responses. In the current study, we aim to investigate the regulatory effect of the epigenetic drug MS-275 on hepatoma G2 (HepG2) cell-derived exosomes, especially for their immunostimulatory properties and alteration of some non-specific immune protein...
