The p53-like Protein CEP-1 Is Required for Meiotic Fidelity in C. elegans
The passage of genetic information during meiosis requires exceptionally high fidelity to prevent birth defects and infertility. Accurate chromosome segregation during the first meiotic division relies on the formation of crossovers between homologous chromosomes and a series of precisely controlled steps to exchange genetic information. Many studies have hinted at a role for p53 in meiosis, bu...
متن کاملC. elegans CEP-1/p53 and BEC-1 Are Involved in DNA Repair
p53 is a transcription factor that regulates the response to cellular stress. Mammalian p53 functions as a tumor suppressor. The C. elegans p53, cep-1, regulates DNA-damage induced germline cell death by activating the transcription of egl-1 and ced-13. We used the C. elegans model to investigate how, in the whole animal, different forms of DNA damage can induce p53-dependent versus p53-indepen...
متن کاملRegulation of Sperm Activation by SWM-1 Is Required for Reproductive Success of C. elegans Males
BACKGROUND Sexual reproduction in animals requires the production of highly specialized motile sperm cells that can navigate to and fertilize ova. During sperm differentiation, nonmotile spermatids are remodeled into motile spermatozoa through a process known as spermiogenesis. In nematodes, spermiogenesis, or sperm activation, involves a rapid cellular morphogenesis that converts unpolarized r...
متن کاملcep-1/p53-dependent dysplastic pathology of the aging C. elegans gonad
The C. elegans germline and somatic gonad are actively developing until the animal reaches adulthood, and then continue to undergo striking changes as the animal ages. Reported changes include a depletion of available sperm, a decrease in oocyte quality up till mid-life, a reduction in germline nuclei, a decrease in fertility, and an accumulation of DNA in the midbody of aging C. elegans. Here,...
متن کاملURI-1 is required for DNA stability in C. elegans.
Unconventional prefoldin RPB5 interactor (URI), an evolutionary conserved member of the prefoldin family of molecular chaperones, plays a central role in the regulation of nutrient-sensitive, TOR (target-of-rapamycin)-dependent gene expression programs in yeast. Mammalian URI has been shown to associate with key components of the transcriptional machinery, including RPB5, a shared subunit of al...
