Although domestic dogs are exceptionally attentive to human social cues, it is unknown whether their sociability is associated with...

Down regulation by a low-zinc diet in gene expression of rat prostatic thymidylate synthase and thymidine kinase

Background Zinc has a wide spectrum of biological activities and its deficiency is related to various abnormalities of cell metabolism. Methods Wistar male rats, at age of 4 weeks, were fed a low-zinc diet for six weeks. The levels of bromodeoxyuridine incorporated into the prostatic DNA and the mRNA expression levels of prostate thymidylate synthase and thymidine kinase were...
