Lesley 1xbet sports betting to present Division of Biology Seminar
Submitted by Division of Biology
Lesley Weaver, assistant professor of biology at Indiana 1xbet sports betting , will present "Regulation of Oogenesis by Nuclear Receptor Signaling" as part of the Division of Biology Seminar Series at 3:30 p.m. Monday, Oct. 4, via Zoom.
The coupling of organism physiology and reproduction is essential for species survival. Nuclear receptors, or NRs, are widely expressed transcription factors that mediate the effects of many circulating factors to modulate physiology and reproduction.1xbet sports betting 's research focuses on an understudied aspect of nuclear receptor signaling in the control of oogenesis. Specifically,1xbet sports betting isinvestigating how the functions of two nuclear receptors — Svp and HR4, the homologs of COUP-TFs and GCNF — in various somatic tissues are integrated to regulate the germline stem cell, or GSC, lineage in the Drosophila ovary. In contrast to many studies focused on the intrinsic roles of nuclear receptor signaling within specific cell types,1xbet sports betting will investigate the circulating factors downstream of Svp and HR4 that remotely regulate various steps of the GSC lineage. For example,1xbet sports betting 's postdoctoral work has revealed that global reduction of Svp activity in somatic cells leads to a reduction in egg laying, GSC maintenance, and survival of early germline cysts and vitellogenic egg chambers. Interestingly,1xbet sports betting found that Svp is required in distinct tissues to control different processes of oogenesis. Furthermore,1xbet sports betting hasfound that Svp regulates the expression of genes involved in immunity and detoxification in fat cells, which may impact successful oogenesis. These results suggest that NRs can have multiple parallel roles in controlling reproduction and that secreted molecules from peripheral tissues can communicate with the ovary to influence oogenesis. As an independent investigator,1xbet sports betting 's lab has continued to address how communication between the ovary and various endocrine organs regulates oogenesis to ensure reproductive fitness.
