Notch signaling is initially identified to play an important role in the developmental control.

GLP-1 could further act in germline and neurons to regulate the transgenerational pollutant toxicity by affecting certain downstream targeted genes.

摘要

Notch signaling is initially identified to play an important role in the developmental control. In Notch signaling pathway of Caenorhabditis elegans, activation of both Notch ligand LAG-2 and Notch receptor GLP-1 mediated transgenerational pollutant toxicity. During this process, TAF-1 and HDA-3 were identified as upregulators for LAG-2 in the germline, and potential transgenerational communication between germline LAG-2 and its receptor GLP-1 may exist. GLP-1 could further act in germline and neurons to regulate the transgenerational pollutant toxicity by affecting certain downstream targeted genes.
