By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.
Live cell imaging shows that the cAMP-sensor Epac2, a target of major antidiabetic drugs, is central to fusion pore control during insulin granule exocytosis.

Germ cell ablation delays C. elegans aging, in part, because unconsumed fat triggers activation of the detoxification factor SKN-1/Nrf, which is regulated by lipid signals and maintains lipid homeostasis.
The ability of the therapeutic glucagon-like peptide-1 receptor agonist liraglutide to promote weight loss is partly dependent on signaling via PKA-dependent phosphorylation of the mTORC1 regulator protein Raptor.
Repression of gene expression by the histone methyltransferase G9a is guided by two zinc finger proteins that can recognize consensus sequences in DNA.

Complementary effects of FBF-1 and FBF-2 on germline stem cell dynamics result from their distinct cooperation with mRNA deadenylase resulting in the opposite effects on the shared target mRNAs.

PCGF6 links sequence specific target recognition by the MAX/MGA transcription factor complex to PRC1 (polycomb repressive complex 1) -dependent transcriptional silencing of germ cell-specific genes in mouse pluripotent stem cells.
