SENP1 inhibits aerobic glycolysis in Aβ-incubated astrocytes by promoting PUM2 deSUMOylation.

Alzheimer's disease (AD), the most prevalent form of dementia in the elderly, involves critical changes such as reduced aerobic glycolysis in astrocytes and increased neuronal apoptosis, both of which are significant in the disease's pathology. In our study, astrocytes treated with amyloid β1-42 (Aβ) to simulate AD conditions exhibited upregulated expressions of small ubiquitin-like modifier (SUMO)-specific protease 1 (SENP1) and Pumilio RNA Binding Family Member 2 (PUM2), alongside decreased levels of Nuclear factor erythroid 2-related factor 2 (NRF2). SENP1 is notably the most upregulated SUMOylation enzyme in Aβ-exposed astrocytes.

Metallothionein rescues doxorubicin cardiomyopathy via mitigation of cuproptosis.

Doxorubicin (DOX), a chemotherapeutic agent utilized in the management of cancer, provokes cardiotoxicity although effective remedy is lacking. Given that DOX provokes oxidative stress and cell death in cardiomyocytes, this study evaluated the possible involvement of cuproptosis, a newly identified form of cell death, in DOX-instigated cardiac remodeling and contractile dysfunction, alongside the impact of the heavy metal scavenger metallothionein (MT) on DOX cardiomyopathy. Cardiac-specific MT transgenic and wild-type (WT) mice were treated with DOX (5 mg/kg/wk.

[Clinical progress in stem cell therapy for end-stage liver disease].

End-stage liver disease includes liver failure and decompensated cirrhosis resulting from various etiologies and often leads to patient mortality due to complications and clinical symptoms such as severe jaundice, ascites, hepatic encephalopathy, coagulopathy, and hepatorenal syndrome. Liver transplantation is currently regarded as the most effective treatment, but its clinical application is limited by the shortage of donors, elevated expenses, and post-transplant rejection. Stem cells are a group of cells with multidirectional differentiation potential and self-renewal ability, which can improve the clinical indicator outcomes through mechanisms such as immunoregulation and promotion of tissue repair in patients with end-stage liver disease.

The positive feedback loop between SP1 and MAP2K2 significantly drives resistance to VEGFR inhibitors in clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is one of the most common and aggressive malignancies of the urinary system. Despite being the first-line treatment for advanced ccRCC, vascular endothelial growth factor receptor inhibitors (VEGFRis) face significant limitations due to both initial and acquired resistance, which impede complete tumor eradication. Using a CRISPR/Cas9 library screening approach, was identified as a resistance-associated gene for three prevalent VEGFRis (Sunitinib, Axitinib, and Sorafenib).
