ATF4, the master regulator of transcription during the Integrated Stress Response (ISR), causes global changes in cysteine sulfhydration of proteins and this event causes cellular metabolic reprogramming.
NMNAT is genetically required for glioma development and promotes glioma growth by allowing a higher tolerance to DNA damage and inhibiting DNA damage-p53-caspase-3 apoptosis signaling pathway by enhancing NAD+-dependent posttranslational modifications (PTMs) poly(ADP-ribosyl)ation (PARylation) and deacetylation of p53.

Electrophysiological and genetic analyses reveal a biophysical mechanism in parvalbumin interneurons, uncoupled from changes in gene expression, resulting in reduced cortical inhibition in early-stage Alzheimer's disease.
Heme-dependent feedback inhibition of rate-limiting ALA-synthesis of plant tetrapyrrole biosynthesis depends on binding of heme to glutamyl-tRNA reductase-binding protein.
The endogenous 3′UTR does not regulate TP53 mRNA or protein level and the 3′UTR is repressive when used alone in reporters, but addition of the coding region has a dominant repressive effect.
A new mode of inflammasome regulation was discovered through a mouse strain intercross that identified the Pycard locus was associated with IL-1β release, and gene editing showed this was due to an SNP in the Pycard mRNA regulating its turnover.
A novel mechanism by which a compartment-specific AAA+ complex mediating organelle biogenesis and protein quality control staves off induction of selective autophagy.

The circadian clock proteins, cryptochrome 1 (Cry1) and 2 (Cry2), evolved from bacterial light-activated DNA repair enzymes to detect DNA damage and coordinate the gene expression response.
