Rab7-regulated ferroptosis contributes to tubular epithelial cells injury by degradation of GPX4 via chaperone-mediated autophagy in AKI.

Evidence suggests that the progression of acute kidney injury (AKI) is driven by tubular epithelial cell (TEC) injury. However, the role of ferroptosis during the regulatory process remains unclear. Fifty-three patients with AKI were included to examine the expressions of Rab7, glutathione peroxidase 4 (GPX4), and Hif-1α by immunohistochemistry.

Molecular subtypes based on ferroptosis-related genes and tumor microenvironment infiltration characterization in lung adenocarcinoma.

Recently, several molecular subtypes with different prognosis have been found in lung adenocarcinoma (LUAD). However, the characteristics of the ferroptosis molecular subtypes and the associated tumor microenvironment (TME) cell infiltration have not been fully studied in LUAD. Using 1160 lung adenocarcinoma samples, we explored the molecular subtypes mediated by ferroptosis-related genes, along with the associated TME cell infiltration.
