Genome-wide RNAi identifies p53-dependent and -independent regulators of germ cell apoptosis in C. elegans.


Lettre, G; Kritikou, E A; Jaeggi, M; Calixto, A; Fraser, A G; Kamath, R S; Ahringer, J; Hengartner, M O (2004). Genome-wide RNAi identifies p53-dependent and -independent regulators of germ cell apoptosis in C. elegans. Cell Death and Differentiation, 11(11):1198-1203.

Abstract

We used genome-wide RNA interference (RNAi) to identify genes that affect apoptosis in the C. elegans germ line. RNAi-mediated knockdown of 21 genes caused a moderate to strong increase in germ cell death. Genetic epistasis studies with these RNAi candidates showed that a large subset (16/21) requires p53 to activate germ cell apoptosis. Apoptosis following knockdown of the genes in the p53-dependent class also depended on a functional DNA damage response pathway, suggesting that these genes might function in DNA repair or to maintain genome integrity. As apoptotic pathways are conserved, orthologues of the worm germline apoptosis genes presented here could be involved in the maintenance of genomic stability, p53 activation, and fertility in mammals.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
