A 59-year-old Chinese male patient was admitted at diagnosis of type 1 diabetes with ketoacidosis. During the normalization of blood glucose with insulin, the patient developed acute hemolysis. The factors predisposing to hemolysis were not found, except the significantly diminished activity of glucose-6-phosphate dehydrogenase (G6PD). DNA analysis did not show any coding or intronic mutation in the G6PD gene. This is the first reported case of a Chinese patient in diabetic ketoacidosis with hemolysis induced by G6PD deficiency in the absence of mutations in the G6PD gene.

Hepatocellular carcinoma (HCC) remains a malignant and life-threatening tumor with an extremely poor prognosis, posing a significant global health challenge. Despite the continuous emergence of novel therapeutic agents, patients exhibit substantial heterogeneity in their responses to anti-tumor drugs and overall prognosis. The pentose phosphate pathway (PPP) is highly activated in various tumor cells and plays a pivotal role in tumor metabolic reprogramming.

Schizothoracine fishes in saltwater lakes of the Tibetan Plateau are important models for studying the evolution and uplift of the Tibetan Plateau. Examining their adaptation to the high-salt environment is interesting. In this study, we first assembled the RNA-Seq data of each tissue of , , and from Qinghai Lake, Selincuo Lake, and Namtso Lake, respectively, obtained by the group previously.

Article Synopsis
- The study investigates the role of glucose-6-phosphate dehydrogenase (G6PD) in exacerbating brain damage caused by cerebral ischemia-reperfusion injury (CIRI) after a stroke.
- Researchers used various methods, including gene analysis and protein studies, to show that G6PD levels increase after ischemic events and that reducing G6PD leads to worsened brain damage and cell survival in models of ischemia.
- The findings suggest a significant link between G6PD and mitophagy, indicating that manipulating G6PD levels could help develop new treatments for brain damage resulting from strokes.
Chuanxiong Rhizoma regulates ferroptosis and the immune microenvironment in ischemic stroke through the JAK-STAT3 pathway.

Ferroptosis is linked to various pathological conditions; however, the specific targets and mechanisms through which traditional Chinese medicine influences ischemic stroke (IS)-induced ferroptosis remain poorly understood. In this study, data from the Gene Expression Omnibus and disease target databases (OMIM, GeneCards, DisGeNet, TTD, and DrugBank) were integrated with ferroptosis-related gene datasets. To identify key molecular targets of Chuanxiong Rhizoma (CX), drug ingredient databases, including PubChem and TCMBank, were employed to map CX-related targets (CX-DEGs-FRG and CX-IS-FRG).

More than two decades ago, in the central-eastern region of the Mediterranean island of Sardinia, a mountain area was identified where the population displays exceptional longevity, especially among men (the Longevity Blue Zone, LBZ). This community was thoroughly investigated to understand the underlying causes of the phenomenon. The present study analyzed 11 genetic markers previously associated with increased survival in several long-lived populations.
