For example, certain probiotics (e.g., lactobacilli ) reportedly activate the NRF2 pathway via metabolic routes [148], while some pathogens (e.g., Salmonella , Helicobacter pylori ) activate NOX1, upregulate ROS, and induce inflammation [149]
Capsiate, a gut microbiota-derived metabolite, inhibits ferroptosis by activating the transient receptor potential vanilloid 1 (TRPV1) channel and upregulating GPX4 expression, thereby alleviating intestinal ischemiareperfusion injury [97]
Therefore, iFSP1, as an FSP1 inhibitor, holds immense potential as a superior therapeutic agent for the treatment of HCC (99,100)
Second, the intermediate metabolites of this pathway serve as vital sources for the generation of glycine and one-carbon units
