Description
Liver fibrosis is a high-morbidity and high-mortality chronic disease throughout the world without any satisfying treatment Large-conductance Ca2+- and voltage-activated K+ (Slo1, BK) channels are widely expressed in human body and important for numerous physiological processes. Previous studies have shown that BK channels are expressed in HSCs of patients with liver fibrosis and they are involved in contraction/relaxation of the HSCs To investigate the molecular mechanism of antifibrotic effect of BK channel opener rottlerin using in vivo fibrosis models. transcriptomic analyses of differential expression genes in livers from rats of vehicle, CCl4 and CCl4 combined with rottlerin treatment were for discrimination. The RNA samples were extracted from three samples of each group for microarray profiling and performed in Affymetrix Rats Genome 230 2.0 arrays for gene expression profiling analysis, which contained 31 042 probe sets. The biotinylated cRNA targets were hybridized with the microarray. After hybridization, arrays were stained in the Fluidics Station 450 and scanned on the Affymetrix Scanner 3000. The microarray experiments were performed by following the protocol of Affymetrix Inc at Shanghai Biotechnology Corporation. Under the criteria fold change > 1.5 or < 0.67, we obtained 10672 differential expressed genes (DEGs) between CCl4 and CCl4 combined with rottlerin treatment group, and the data was applied to further analysis.

Description
The serine threonine kinase Stk40 has been shown to involve in mouse embryonic stem cell differentiation, pulmonary maturation and adipocyte differentiation. Here we report that targeted deletion of Stk40 leads to fetal liver hypoplasia and anemia in the mouse embryos. The reduction of erythrocytes in the fetal liver is accompanied by increased apoptosis and compromised erythroid maturation. Stk40-/- fetal liver cells have significantly reduced colony forming units (CFUs) capable of erythroid differentiation, including burst forming unit-erythroid (BFU-E), colony forming unit-erythroid (CFU-E), and CFU-granulocyte, erythrocyte, megakaryocyte and macrophage (CFU-GEMM), but not CFU-granulocyte/macrophages (CFU-GM). Purified Stk40-/- megakaryocyte-erythrocyte progenitors (MEPs) produced substantially fewer CFU-E colonies compared to control cells. Moreover, Stk40-/- fetal liver erythroblasts failed to form normal erythroblastic islands in association with wild type or Stk40-/- macrophages, indicating an intrinsic defect of Stk40-/- erythroblasts. Furthermore, the hematopoietic stem and progenitor cell pool is reduced in Stk40-/- fetal livers but still retains the multi-lineage reconstitution capacity. Finally, analysis of microarray data of E14.5 fetal liver cells suggests a potential role of aberrantly activated TNF- signaling in Stk40 depletion induced dyserythropoiesis with a concomitant increase in cleaved Caspase-3 and decrease in Gata1 proteins. Altogether, the identification of Stk40 as a regulator for fetal erythroid differentiation, maturation and survival provides new clues to the molecular regulation of erythropoiesis and related diseases.

Description
Collagen triple helix repeat containing 1 (CTHRC1) has been found to be up-regulated in many human solid tumors. In this study, we investigated the changes of gene expression by comparing CTHRC1-siRNA and Scramble-siRNA control in hepatocellular carcinoma cell line HCCLM3, which has high expression levels of CTHRC1.

Description
Mutations of SMAD family member 4 (Smad4) gene caused Hereditary Hemorrhagic Telangiectasia (HHT). It was believed that bleeding disorders were caused by arteriovenous malformation in this syndrome. Although several studies indicated dysfunction of platelets from HHT patient, the role(s) of smad4 in platelet function has not been examined. In this study, using megakaryocyte/platelet-specific Smad4-deficient mice, we investigated the physiological function of Smad4 in platelet activation and the underlying mechanism.

Description
Baicalein, a purified flavonoid compound with defined chemical structure extracted from the dry roots of Scutellaria radix that is a broadly used herb in China, has been proved to possess significant anti-hepatoma activity by inhibiting cell proliferation, invasion, metastasis and inducing apoptosis, autophagy via several cancer-related signaling molecules. In recent years, emerging studies have demonstrated that Chinese medicinal herbs can exert their anti-tumor effects through targeting lncRNAssuch as curcumin, camptothecin, resveratrolpaclitaxel. However, there is still no related report about the effects of baicalein on lncRNA expression profile when it exerts its inhibition on hepatoma tumor growth. To investigate whether the antitumor effect of baicalein is related to its modulation of lncRNA expression in hepatocellular carcinoma (HCC), we profiled the lncRNA expression in HCC cell line Bel-7402 treated with baicalein (0, 40, 80M) for 24 hours using lncRNA microarray and detected the changes by comparing the lncRNA expression profile of HCC cell line Bel-7402 treated with baicalein (40 and 80 M) and its DMSO control (0 M). These findings suggest that modulation of lncRNA expression may be an important mechanism underlying the anti-hepatoma effects of baicalein and lay the groundwork for further investigations.
