Mechanism of Insulin Resistance.
Nippon Ronen Igakkai Zasshi. Japanese Journal of Geriatrics, 1999 インスリン抵抗性の成因は遺伝素因, 肥満などの生活習慣, 高血糖それ自体に大別される. 肥満に伴うインスリン抵抗性は肥大した脂肪細胞から分泌されるTNF-αや遊離脂肪酸 (FFA) が関与している. インスリン抵抗性の分子レベルでの共通の特徴は, (1)インスリン受容体チロシンキナーゼ・P13キナーゼ活性の低下, (2)GLUT4トランスロケーションと糖取り込み低下, (3)グリコーゲン合成酵素活性低下である. インスリン抵抗性は, 膵β細胞のインスリン分泌能や増殖能に障害のある場合には, 2型糖尿病の強力な発症要因となる. 最近, 糖代謝に関するインスリン作用に加えて, 血管や腎でのインスリン作用が解明されつつある.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Mechanisms of Immune Resistance [PDF]
, 2018 AbstractRelapse represents one of the main unsolved issues in allogeneic HCT, prompting research on its underlying mechanisms. Growing evidence support the hypothesis that in many patients relapse is driven by immune changes in cancer cells and in the supporting microenvironment, abrogating the graft-versus-tumor effect.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
