Biochemical and genetic studies reveal a third transcription factor, BHLHE40, that together with LXR and C/EBPβ mediates insulin induction of SREBP-1c, which in turn leads to triglyceride accumulation in liver.
The pseudokinase Tribbles1 is expressed in human monocytes after mycobacterial challenge and can be manipulated to be host protective against mycobacterial infection, due to control of innate immune cell function, in a zebrafish tuberculosis model.
DNA methylation status can be exploited to finely and reversibly tune the expression of highly inducible genes with CpG-poor promoters in response to environmental cues.

ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.
Integrated stress response-induced expression of ATF4 and its transactivation of SOX9 causes aberrant chondrocyte differentiation and skeletal defects which can be alleviated by modulating initiation-factor eIF2α phosphorylation translation control.
