    Global warming has increased summer temperatures, leading to a rise in heat stroke-related deaths in Japan. Heat stroke disrupts the body's adaptation to high temperatures, often resulting in severe complications, including liver damage and even death. However, despite the increasing incidence, pathological autopsies remain rare, and the histological changes associated with heat stroke are poorly understood. In this study, we investigated the pathogenesis of heat stroke using a mouse model. Mice were exposed to 45 °C for 30 min and dissected immediately or 24, 48, and 72 h post-exposure. Histological analysis revealed significant lipid accumulation in hepatocytes surrounding the central vein at 24, 48, and 72 h. At 24 h, hepatocytes also exhibited features of early degeneration, including cytoplasmic lysis and chromatin condensation. Lipidomics analysis of liver tissue collected 24 h post-exposure demonstrated a marked increase in 27-hydroxycholesterol levels. These results indicate that heat stress rapidly disrupts hepatic lipid homeostasis, causing cellular damage and metabolic remodeling. The observed lipid accumulation, including elevated 27-hydroxycholesterol, may play dual roles in mediating inflammation and serving as a protective response. Our findings provide new insight into the pathogenesis of heat stroke-induced liver injury and suggest potential molecular targets for early diagnosis and intervention.

    In contrast to the robust proliferation exhibited following acute liver injury, hepatocytes exhibit long-lasting proliferative activity in chronic liver injury. The mechanistic differences between these distinct modes of proliferation are unclear. Hepatocytes exhibited robust proliferation that peaked at 2 days following partial hepatectomy in mice, but this proliferation was completely inhibited by hepatocyte-specific expression of MadMyc, a Myc-suppressing chimeric protein. However, Myc suppression induced weak but continuous hepatocyte proliferation, thereby resulting in full restoration of liver mass despite an initial delay. Late-occurring proliferation was accompanied by prolonged suppression of proline dehydrogenase (PRODH) expression, and forced PRODH overexpression inhibited hepatocyte proliferation. In hepatocytes in chronic liver injury, Myc was not activated but PRODH expression was suppressed in regenerating hepatocytes. In liver tumors, PRODH expression was often suppressed, especially in the highly proliferative tumors with distinct Myc expression. Our results indicate that the robust proliferation of hepatocytes following acute liver injury requires high levels Myc expression and that there is a compensatory Myc-independent mode of hepatocyte proliferation with the regulation of proline metabolism, which might be relevant to liver regeneration in chronic injury.

  • Treatment of hepatocellular carcinoma with autologous platelets encapsulating sorafenib or lenvatinib: A novel therapy exploiting tumor-platelet interactions. Reviewed International journal

    Hepatocellular carcinoma (HCC) activates platelets through the action of adjacent sinusoidal cells. Activated platelets bind to tumor-associated endothelial cells and release growth factors that promote tumor progression. We hypothesized that platelets encapsulated with tumor inhibitors would function as drug carriers for tumor therapy. We propose a therapeutic strategy for HCC using autologous platelets encapsulating multiple tyrosine kinase inhibitors in a rat chemically induced HCC model. Sorafenib or lenvatinib was encapsulated in platelets isolated from tumor-bearing rats in vitro. The rats were divided into groups that received repeated intravenous injections (twice a week for 10 weeks) of the following materials: placebo, sorafenib (SOR), lenvatinib (LEN), autologous platelets, autologous platelets encapsulating sorafenib (SOR-PLT) and autologous platelets encapsulating lenvatinib (LEN-PLT). The therapeutic effect was then analyzed by ultrasonography (US) and histopathological analysis. Histopathological and US analysis demonstrated extensive tumor necrosis in the tumor tissue of SOR-PLT or LEN-PLT, but not in other experimental groups. By liquid chromatography-mass spectrometry, more abundant sorafenib was detected in tumor tissues after SOR-PLT administration than in surrounding normal tissues, but no such difference in sorafenib level was observed with SOR administration. Therefore, the use of autologous platelets encapsulating drugs might be a novel therapeutic strategy for HCC.

  • Decreased Portal Circulation Augments Fibrosis and Ductular Reaction in Nonalcoholic Fatty Liver Disease in Mice Reviewed International journal

    Nonalcoholic fatty liver disease often progresses to cirrhosis and causes liver cancer, but mechanisms of its progression have not been elucidated. Although nonalcoholic fatty liver disease is often associated with abnormal portal circulation, there have not been any experimental studies to test its pathogenic role. Here, whether decreased portal circulation affected the pathology of nonalcoholic steatohepatitis (NASH) was examined using congenital portosystemic shunt (PSS) in C57BL/6J mice. Whereas PSS significantly attenuated free radical-mediated carbon tetrachloride injury, it augmented pericellular fibrosis in the centrilobular area induced by a 0.1% methionine choline-deficient l-amino acid-defined high-fat diet (CDAHFD). PSS aggravated ductular reaction and increased the expression of connective tissue growth factor. Pimonidazole immunohistochemistry of the liver revealed that the centrilobular area of PSS-harboring mice was more hypoxic than that of control mice. Although tissue hypoxia was observed in the fibrotic area in CDAHFD-induced NASH in both control and PSS-harboring mice, it was more profound in the latter, which was associated with higher carbonic anhydrase 9 and vascular endothelial growth factor expression and neovascularization in the fibrotic area. Furthermore, partial ligation of the portal vein also augmented pericellular fibrosis and ductular reaction induced by a CDAHFD. These results demonstrate that decreased portal circulation, which induces hypoxia due to disrupted intralobular perfusion, is an important aggravating factor of liver fibrosis in NASH.

  • Helicobacter pylori CagA oncoprotein interacts with SHIP2 to increase its delivery into gastric epithelial cells Reviewed International journal

    Chronic infection with Helicobacter pylori cagA-positive strains is causally associated with the development of gastric diseases, most notably gastric cancer. The cagA-encoded CagA protein, which is injected into gastric epithelial cells by bacterial type IV secretion, undergoes tyrosine phosphorylation at the Glu-Pro-Ile-Tyr-Ala (EPIYA) segments (EPIYA-A, EPIYA-B, EPIYA-C, and EPIYA-D), which are present in various numbers and combinations in its C-terminal polymorphic region, thereby enabling CagA to promiscuously interact with SH2 domain-containing host cell proteins, including the prooncogenic SH2 domain-containing protein tyrosine phosphatase 2 (SHP2). Perturbation of host protein functions by aberrant complex formation with CagA has been considered to contribute to the development of gastric cancer. Here we show that SHIP2, an SH2 domain-containing phosphatidylinositol 5'-phosphatase, is a hitherto undiscovered CagA-binding host protein. Similar to SHP2, SHIP2 binds to the Western CagA-specific EPIYA-C segment or East Asian CagA-specific EPIYA-D segment through the SH2 domain in a tyrosine phosphorylation-dependent manner. In contrast to the case of SHP2, however, SHIP2 binds more strongly to EPIYA-C than to EPIYA-D. Interaction with CagA tethers SHIP2 to the plasma membrane, where it mediates production of phosphatidylinositol 3,4-diphosphate [PI(3,4)P2 ]. The CagA-SHIP2 interaction also potentiates the morphogenetic activity of CagA, which is caused by CagA-deregulated SHP2. This study indicates that initially delivered CagA interacts with SHIP2 and thereby strengthens H. pylori-host cell attachment by altering membrane phosphatidylinositol compositions, which potentiates subsequent delivery of CagA that binds to and thereby deregulates the prooncogenic phosphatase SHP2.
