Liver fibrosis is a risk factor for hepatoma. Activated hepatic stellate cells (HSCs) play a critical role in progression of hepatoma. Resected hepatoma patients with high α-SMA+HSCs infiltration had worse survival, OR: 2.2 and p=0.0434. We hypothesized that HSCs could increase the epithelial-mesenchymal transition (EMT) ability of hepatoma cells. In murine model of liver fibrosis with injectio...

Lipopolysaccharide (LPS) has been shown to protect certain cultured mammalian cells from undergoing programmed cell death (apoptosis) when exposed to tumor necrosis factor (TNF). However, LPS has also been reported to induce apoptosis in cultured endothelial cells, suggesting that apoptotic response mechanisms may be dependent upon cell type. In order to understand the influence of tissue-speci...

Mitochondria were isolated from whole homogenates of normal liver and Novikoff hepatomas using reorienting rate zonal centrifugation on sucrose gradients. The activities of several mitochondrial-specific enzymes and ultrastructure were compared in the two tissues. Our results indicate that cytochrome oxidase, lipoamide dehydrogenase, malate dehydrogenase, and succinate dehydrogenase activities ...

A systematic study of the carbohydrate-metabolizing enzyme systems of the Morris hepatoma 51~3 was carried out, and results were interpreted in the light of normal liver data and in comparison with previously established values of Novikoff hepatoma. The cellularity of the Morris tumor was in the same range, whereas the nitrogen content of the average cell was significantly decreased, as compare...

The pathway of fat oxidation in two experimental hepatomas was studied in order to demonstrate that a specific deficit in the energy metabolism of a tumor might contribute to the cachexia of the host. Forty-eight male Buffalo rats were divided into four groups of 12 each. One group was implanted s.c. with Morris hepatoma 7777 and one group was implanted with Morris hepatoma 7800, whereas the ot...

Tissue factor pathway inhibitor (TFPI) is a plasma Kunitz-type serine protease inhibitor that directly inhibits coagulation Factor Xa and also inhibits tissue factor-initiated coagulation. Normal human plasma TFPI exists both as the full-length molecule and as variably carboxy-terminal truncated forms. We reported recently that the low density lipoprotein receptor-related protein mediates the c...

Background & AimsAlthough the tumor microenvironment plays an important role in growth, it is not fully understood what hepatic stellate cells (HSCs) play hepatocellular carcinoma (HCC) microenvironment.MethodsA high-fat diet after streptozotocin was administered to HSC-specific Atg7-deficient (GFAP-Atg7 knockout [KO]) or growth differentiation factor 15 (GDF15)-deficient (GFAP-GDF15KO) mice. L...

The root of Actinidia valvata dunn has been widely used in the treatment of hepatocellular carcinoma (HCC), proved to be beneficial for a longer and better life in China. In present work, total saponin from root of Actinidia valvata Dunn (TSAVD) was extracted, and its effects on hepatoma H22-based mouse in vivo were observed. Primarily transplanted hypodermal hepatoma H22-based mice were used t...
