Correlated to these results, SBP1 promoter showed enhanced activity in response to sulfur starvation. The sulfur starvation induction of SBP1 was abolished by feeding the plants with glutathione (GSH) and was enhanced when seedlings were treated simultaneously with buthionine sulfoxide, which inhibits ...

inducing the maturation of DCs and enhancing immune response. Activated APCs like DCs and macrophages reduce Cys2into Cys to supply CD8+T cells for GSH synthesis. MDSCs with a powerful intracellular storage
and continuous efferocytosis by macrophages. The catabolism of phagocytosed apoptotic cells by macrophages leads to an increase in the OCR fueled by FAO. In this context, ETC dysfunction by depletion of Rieske iron-sulfur protein (RISP), an essential subunit of mitochondrial complex III, in LysM...
Expression regulation Phosphate limitation induces genes that encode phosphate- liberating enzymes to provide sufficient inorganic phosphate for survival under conditions of phosphate starvation. The E. coli alkaline phosphatase gene phoA is part of the phos- phate regulon, and its express...
Gcn4 is also a master transcriptional regulator that mediates the cellular response to amino acid starvation38. It activates transcription by recruiting multiple coactivators, including the mediator complex, the SAGA complex, and the SWI/SNF complex, to enable assembly of the pre-initiation complex at...
[96,97]. However, bacteria can adapt to changes in environmental itaconate levels in several ways. For example,Staphylococcus aureusexperiences ammonium starvation under itaconate stress [98], and the LysR-type transcriptional regulator RipR protects Gram-negative bacteria from itaconate challenges [99]...
(OSKM) is a therapeutic strategy for tissue regeneration and rejuvenation, but little is known about its metabolic requirements. Here we show that OSKM reprogramming in mice causes a global depletion of vitamin B12and molecular hallmarks of methionine starvation. Supplementation with vitamin B12increases...
since it is degraded in the following night to sustain metabolism, energy production and biosynthesis in the absence of photosynthesis. If this night-time carbohydrate supply is reduced—for instance in mutants impaired in starch synthesis—plants grow more slowly and experience acute starvation [4]....
