Background: In regions with a high prevalence of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, coinfected patients face a heightened risk of developing hepatocellular carcinoma (HCC), termed HBV/HCV-related HCC (HBCV-HCC). We aimed to investigate the contribution of preexisting chronic hepatitis B (CHB) and subsequent chronic hepatitis C (CHC) to the development of HBCV-HCC.

Methods: We examined HBV's involvement in 93 HBCV-HCC cases by analyzing HBV DNA integration as an indicator of HCC originating from HBV-infected hepatocytes, compared with 164 HBV-HCCs and 56 HCV-HCCs as controls.

Excessive BMP3b suppresses skeletal muscle differentiation.

Biochem Biophys Res Commun

February 2025

Molecular Signaling and Biochemistry, Kyushu Dental University, Kokurakitaku, Kitakyushu, Fukuoka, Japan.

Bone morphogenetic protein (BMP)-3b, also known as growth differentiation factor (GDF)-10, belongs to the transforming growth factor (TGF)-β superfamily. Despite being named a BMP, BMP3b is considered as an intermediate between the TGFβ/activin/myostatin and BMP/GDF subgroups of the TGFβ superfamily. Myoblast differentiation is tightly regulated by various cytokines, including the TGFβ superfamily members.

The mitochondrial pyruvate dehydrogenase complex (PDC) plays a crucial role in linking the glycolysis pathway and the tricarboxylic acid (TCA) cycle. Previously, we reported that a mutation of , encoding an E1β subunit of PDC, affects the abundance of auxin efflux carriers PIN-FORMED proteins (PINs) via reduced recycling and enhanced degradation in vacuoles. Here, we further analyzed the effects of TCA cycle inhibition on vesicle trafficking using both the mutant and 3-BP, a TCA cycle inhibitor.

Article Synopsis
  • Minamata disease is a severe neurological disorder caused by methylmercury (MeHg) poisoning, identified in Japan in 1956, and previously thought to be linked to elevated selenium (Se) levels in patients.
  • Research showed both mercury and selenium were present in historical samples from Minamata Bay, indicating that Se also contaminated the area and accumulated in patients' organs.
  • The study's findings, including high Hg/Se molar ratios in brain tissue, help explain the neurological damage seen in patients and emphasize the dangers of consuming MeHg-contaminated seafood.

Soft tissue and bone tumors are rare, and their low frequency and diverse histological types make conducting large-scale clinical trials challenging. Patient-derived xenografts (PDX), entailing implantation of cancer specimens in immunocompromised mice, are emerging as a valuable translational model because PDX keeps the original tumors' character and drug sensitivity. We sequentially transplanted 166 surgical and biopsy specimens from orthopedic surgeries, including 138 soft tissue and bone tumors (81 malignant, 23 intermediate, and 34 benign), 16 metastatic bone tumors, 9 hematological malignancies, and 3 non-tumor tissues.

Recent changes in climate and environments have promoted the range expansion of insect pests of tropical and subtropical origins into temperate regions. For more accurate and faster risk assessment of this expansion, we developed a novel indicator to link a physiologically derived parameter of chilling injury with the survival of insect populations in nature by using two insects, Spodoptera frugiperda and Cicadulina bipunctata with tropical and subtropical origins, and one cool-adapted insect, Laodelphax striatellus. The parameter derived from a proportional increment in the time to 99.

Kumamoto University Regional Centre, The Japan Environment and Children's Study (JECS), 718, Medical Research Building, 1-1-1 Honjo, Chuo-ku, Kumamoto, Kumamoto, 860-8556, Japan.

Background: Antinuclear antibodies (ANA) are important biomarkers for the diagnosis of autoimmune diseases; however, the general population also tests positive at a low frequency, especially in women. Although the effects of various autoimmune diseases on pregnancy outcomes have been studied, the association of ANA with pregnancy outcomes in healthy individuals is unclear. Preterm birth (PTB), a major cause of neonatal death or long-term health problems, is a complex condition with a multifactorial etiology, and the underlying mechanism remains unclear.

Background And Study Aims: Diffuse infiltrative gastric cancer can be difficult to diagnose owing to a lack of endoscopic features in the superficial mucosa. Moreover, a forceps biopsy may not reveal a pathological diagnosis. We aimed to evaluate the diagnostic yield and safety of endoscopic mucosal resection (EMR) and 'open-lid submucosal biopsy', a technique wherein EMR followed by biopsy of the ulcer floor is performed for a pathological diagnosis.
