SNAI1, a zinc-finger transcription factor, plays an important role in the induction of epithelial-mesenchymal transition (EMT) in various cancers. However, the possible functions of SNAI1 in the proliferation and apoptosis of hepatocellular carcinoma have not been clearly identified. In this study, we investigated the effects and mechanisms of SNAI1 in the proliferation and apoptosis of hepatoc...

Objective(s): Although low-dose radiotherapy (RT) that involves low collateral damage is more suitable for hepatocellular carcinoma (HCC) than traditional high-dose RT, but to achieve satisfactory therapeutic effect with low-dose RT, it is necessary to sensitize HCC cells to irradiation. This study was aimed to determine whether radiosensitivity of HCC cells can be enhanced using miR-26b by tar...

BACKGROUND We have reported previously that overexpression of glucose-regulated protein 78 (GRP78) promotes the invasion of hepatocellular carcinoma. However, whether GRP78 knockdown affects the extracellular matrix degradation has not been elucidated. Here we are going to determine whether GRP78 knockdown affect the ECM degradation and the role of MMP-2 and MMP-9 in these process in hepatocell...

five flavonoid glycosides were isolated from the n-butanol soluble fraction of the ethanolic extract of rapistrum rugosum and their structures were assigned from 1h- and 13c-nmr spectra (dept) with 2d nmr as quercetin-3-o-α-l-rhamnopyranoside (1), quercetin-3-o-β-d-xyloside (2), quercetin, 3-o-α-l-arabinopyranoside,7-o-α-l-rhamnopyranoside (3), kaempferol 3-o-α-l-arabinopyranoside, 7-o-α-l-rham...

Second line therapy after failure of sorafenib continues to be under study. Prognosis of hepatocellular carcinoma is measured in months, with median overall survival reaching 10.7 months with sorafenib. Because of the modest net benefit sorafenib has contributed, and rising incidence of hepatocellular carcinoma in the world, continued efforts are ongoing to look for efficient upfront, second li...

Fifteen nude mice were inoculated with a human neuroblastoma cell line and 14 with a human primary hepatocellular carcinoma cell line. Human ferritins were detected in the sera of the mice which developed tumors. Of 14 mice bearing human neuroblastoma, 12 had human liver-type ferritin (8 to 52 ng/ml) in their sera, and three of these also had HeLa-type ferritin (acidic ferritin) (29 to 40 ng/ml...

The marked induction of cytochromes P450 such as CYP1A1 caused by polycyclic aromatic hydrocarbons (PAHs) like 3-methylcholanthrene (MC) is often accompanied by suppression of other hepatic P450s. The molecular mechanisms, functional consequences, and human relevance of P450 downregulation by PAHs are poorly understood. MC suppresses mRNA levels for CYP2C8, an important human P450, in cultured ...

Natural killer (NK) cells have been demonstrated to inhibit tumor growth. However, the role of NK cells in the inhibition of hepatocellular carcinoma metastasis is not well understood. The present study aimed to investigate the roles that NK cells may serve in inhibiting hepatocellular carcinoma metastasis. The role of isolated NK cells in the inhibition, proliferation, migration and invasion o...
