Phosphocreatine-mediated enhancement of mitochondrial function for accelerated healing of diabetic foot ulcers through the PGC-1α-NRF-1 signaling pathway.

Diabetic foot ulcers (DFUs) pose a significant clinical challenge due to their slow healing and high risk of complications, which severely affect patient quality of life. Central to the delayed healing observed in DFUs is mitochondrial dysfunction, a critical factor impairing cellular repair processes. Phosphocreatine (PCr), a vital molecule involved in cellular energy buffering and ATP regeneration, has recently emerged as a promising therapeutic candidate for ameliorating mitochondrial dysfunction and enhancing tissue repair.

Urethra-preserving and dorsal capsule fenestration with robot-assisted simple prostatectomy for severe LUTS in small prostate: a case report.

Methods: Obesity model was established by feeding rats with a high-fat diet, and H9c2 cells were stimulated with palmitic acid to mimic high-fat stimulation.

Arsenic inducible islet β-cell dysfunction and ferroptosis through mA-YTHDF2-dependent CHAC1 enhancement.

Arsenic, recognized as an environmental and food contaminant, has been linked to the dysfunction of islet β-cells, the primary lesions in type 2 diabetes (T2D). Ferroptosis, a regulated cell death pathway dependent on GPX4, has been implicated in arsenic-induced β-cell dysfunction. However, the underlying molecular mechanisms remain unclear.

Atractylenolide-III restrains cardiac fibrosis after myocardial infarction via suppression of the RhoA/ROCK1 and ERK1/2 pathway.

Background: Cardiac fibrosis, a critical factor in myocardial remodeling post-myocardial infarction (MI), can advance heart failure progression. Atractylenolide III (ATL-III), derived from Atractylodes lancea, has recognized antioxidant and anti-inflammatory effects; however, its influence on cardiac fibrosis remains unclear.

Methods: MI was induced in mice by permanent ligation of the left anterior descending (LAD) coronary artery, followed by 2 weeks of ATL-III or dimethyl sulfoxide (DMSO) treatment.

Using the SEIQR model with epidemic amplifier effect to predict the final outbreak size of the COVID-19 in Dalian, Liaoning province, China.

Methods: This study retrospectively included 172 patients with EOC preoperatively underwent dual-energy CT scans. Patients were grouped as type I and type II EOC according to postoperatively pathologic results.

The Lyn/RUVBL1 Complex Promotes Colorectal Cancer Liver Metastasis by Regulating Arachidonic Acid Metabolism Through Chromatin Remodeling.

Liver metastasis is a common cause of death in colorectal cancer (CRC) patients, but epigenetic remodeling and metabolic reprogramming for CRC liver metastasis remain unclear. The study revealed that the Lyn/RUVBL1 complex is highly expressed in CRC and is closely correlated with liver metastasis. On the one hand, ATAC-seq and HiCut suggested that Lyn/RUVBL1 regulates the expression of TRIB3 through the POL II-mediated chromatin conformation of TRIB3 and thus the expression of β-catenin.

Hypoxia Reduces Mouse Urine Output via HIF1α-Mediated Upregulation of Renal AQP1.

Introduction: Patients with acute mountain sickness (AMS) due to hypoxia at high altitudes often exhibit abnormal water metabolism. Hypoxia-inducible factors (HIFs) are major regulators of adaptive responses to hypoxia. As transcription factors, HIFs are involved in the regulation of erythropoiesis, iron metabolism, angiogenesis, energy metabolism, and cell survival by promoting the transcriptional expression of hundreds of target genes.
