Overexpression of sirtuins (NAD(+)-dependent protein deacetylases) has been reported to increase lifespan in budding yeast (Saccharomyces cerevisiae), Caenorhabditis elegans and Drosophila melanogaster. Studies of the effects of genes on ageing are vulnerable to confounding effects of genetic background. Here we re-examined the reported effects of sirtuin(More)
BACKGROUND Lipid phosphate phosphatases (LPPs) are integral membrane proteins believed to dephosphorylate bioactive lipid messengers, so modifying or attenuating their activities. Wunen, a Drosophila LPP homologue, has been shown to play a pivotal role in primordial germ cell (PGC) migration and survival during embryogenesis. It has been hypothesised that(More)
Estrogen is an essential requirement for the postpubertal trophic development and maintenance of the differentiated state of the oviduct, uterus, cervix, vagina and mammary glands of mammals. Estrogen, apparently functioning through its specific cytoplasmic receptor protein via a multistep interaction pathway induces gene expression of specific biochemical(More)
