Molecular Oncology, EarlyView.In prostate carcinoma, lactic acid, secreted by highly glycolytic cancer‐associated fibroblasts, is imported into tumor cells through the MCT1 transporter and prevents RSL3 and erastin‐induced ferroptosis (A). Targeting of carbonic anhydrase IX/XII, the main extracellular pH regulators, in tumor and stromal cells reduces microenvironmental acidosis and

Gut alterations in a chronic kidney disease rat model with diet‐induced vascular calcification
FEBS Open Bio, EarlyView.Chronic kidney disease (CKD) patients often suffer from intestinal and/or mineral and bone disorders. Using a rat model, we showed that uremic vascular calcification is associated with gut barrier alterations (decreased gut mucus production and Nlrp6 gene expression, increased gut inflammation), and plasma retention of gut‐origin uremic toxins (indoxyl
