The lim-7p::ced-1::GFP transgene from the MD701 strain increases embryonic lethality in C. elegans.

The lim-7p::ced-1::GFP transgene has been widely used for evaluating germline apoptosis in C. elegans . Here we observed an increase in embryonic lethality in the MD701 strain that contains the lim-7p::ced-1::GFP transgene and a strain that outcrossed the lim-7p::ced-1::GFP transgene into the N2 wild-type strain. While the outcrossed strain had a significantly lower level of embryonic lethality than MD701, it still showed significantly higher embryonic lethality than wild type. Our results suggest that the presence of the lim-7p::ced-1::GFP transgene significantly increases embryonic lethality, but there may also be a secondary mutation in the MD701 strain that further increases embryonic lethality.

NIH is the nations medical research agency - making important medical discoveries that improve health and save lives. The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the primary Federal agency for conducting and supporting medical research. Helping to lead the way toward important medical discoveries that improve peoples health and save lives, NIH scientists investigate ways to prevent disease as well as the causes, treatments, and even cures for common and rare diseases. NIH research impacts: * child and teen health, * men's health, * minority health, * seniors' health, * women's health, and * wellness and lifestyle issues. Composed of 27 Institutes and Centers, the NIH provides leadership and financial support to researchers in every state and throughout the world.
