Partial Inhibition of HO-1 Attenuates HMP-Induced Hepatic Regeneration against Liver Injury in Rats.

We found better liver graft regeneration with hypothermic machine perfusion (HMP) compared with static cold storage (SCS) for the first time in our pilot study, but the underlying mechanisms are unknown. Upregulated heme oxygenase- (HO-) 1 expression has been reported to play a pivotal role in promoting hepatocyte proliferation. Here, we evaluated the novel role of HO-1 in liver graft protection by HMP.

evaluation of bronchial injury of irreversible electroporation in a porcine lung ablation model by using laboratory, pathological, and CT findings.

Irreversible electroporation (IRE) creates permanent pores in the cell membrane, leading to irreversible cell death. In this study, the impact of IRE on bronchial injury was comprehensively examined in a timed series study. Altogether, 8 Bama miniature pigs were included in this study and were randomly assigned to experimental and control groups.

Cytokines are early diagnostic biomarkers of graft-versus-host disease in liver recipients.

Background: Graft-versus-host disease (GVHD) is associated with high mortality. Early diagnosis is essential to start treatment and to improve outcomes. Because of the inflammatory nature, we hypothesis that cytokine profile of patients with GVHD may serve as diagnostic markers.

Porta hepatic schwannoma: case report and a 30-year review of the literature yielding 15 cases.

Background: Schwannomas located in the periportal region are extremely rare. Only 14 cases have been reported in the medical literature worldwide. Cases of porta hepatic schwannomas reported in the literature worldwide were reviewed.

Solanine-induced reactive oxygen species inhibit the growth of human hepatocellular carcinoma HepG2 cells.

The aim of the present study was to investigate the effect of solanine on promoting human hepatocellular carcinoma HepG2 cells to produce reactive oxygen species (ROS), and the molecular mechanisms leading to tumor cell apoptosis. Solanine was administered to HepG2 cells . A selection of probes targeting various cellular localizations of ROS were used to detect ROS expression using flow cytometry.

Akt‑mediated phosphorylation of Oct4 is associated with the proliferation of stem‑like cancer cells.

Oct4 protein encoded by POU5F1 plays a pivotal role in maintaining the self‑renewal of pluripotent stem cells; however, its presence in cancer cells remains controversial. In the present study, we provided evidence that the transcripts of authentic OCT4 gene (OCT4A) and its multiple pseudogenes were detected in a variety of cancer cell lines. A few major bands were also detected by western blotting using an anti‑Oct4A monoclonal antibody.

Hepatocyte differentiation of human fibroblasts from cirrhotic liver in vitro and in vivo.

Background: Mesenchymal stem cells (MSCs) and fibroblasts have intimate relationships, and the phenotypic homology between fibroblasts and MSCs has been recently described. The aim of this study was to investigate the hepatic differentiating potential of human fibroblasts in cirrhotic liver.

Methods: The phenotypes of fibroblasts in cirrhotic liver were labeled by biological methods.

Modulation of Cx46 hemichannels by nitric oxide.

Gap-junction hemichannels are composed of six protein subunits (connexins). Undocked hemichannels contribute to physiological autocrine/paracrine cell signaling, including release of signaling molecules, cell-volume regulation, and glucose uptake. In addition, hemichannels may be pathologically activated by dephosphorylation and cell-membrane depolarization.

Stem-like cells in hepatitis B virus-associated cirrhotic livers and adjacent tissue to hepatocellular carcinomas possess the capacity of tumorigenicity.

Background And Aim: Recent investigations demonstrate that adult stem cells may be targets for malignant transformation and that the stem-like cells in diseased livers possess the capacity of tumorigenicity in animal models. The aim of this study is to examine expression patterns of stem-cell markers in hepatitis B virus-associated cirrhotic livers and hepatocellular carcinomas (HCC), and to investigate the stem-like cell capacity of tumorigenicity in these tissues.

Methods: Twenty surgically resected HCCs and corresponding adjacent tissues as well as 10 cirrhotic liver tissues were collected and immunohistochemical staining were performed to detect the expression of CD34, Thy-1, CD133, and c-kit.
