Targeting aldehyde dehydrogenase ALDH3A1 increases ferroptosis vulnerability in squamous cancer.

Ferroptosis is a unique modality of regulated cell death induced by excessive lipid peroxidation, playing a crucial role in tumor suppression and providing potential therapeutic strategy for cancer treatment. Here, we find that aldehyde dehydrogenase-ALDH3A1 tightly links to ferroptosis in squamous cell carcinomas (SCCs). Functional assays demonstrate the enzymatic activity-dependent regulation of ALDH3A1 in protecting SCC cells against ferroptosis through catalyzing aldehydes and mitigating lipid peroxidation.

Lysosomes finely control macrophage inflammatory function via regulating the release of lysosomal Fe through TRPML1 channel.

Lysosomes are best known for their roles in inflammatory responses by engaging in autophagy to remove inflammasomes. Here, we describe an unrecognized role for the lysosome, showing that it finely controls macrophage inflammatory function by manipulating the lysosomal Fe-prolyl hydroxylase domain enzymes (PHDs)-NF-κB-interleukin 1 beta (IL1B) transcription pathway that directly links lysosomes with inflammatory responses. TRPML1, a lysosomal cationic channel, is activated secondarily to ROS elevation upon inflammatory stimuli, which in turn suppresses IL1B transcription, thus limiting the excessive production of IL-1β in macrophages.
