Biochemical and Molecular Roles of Nutrients Lactase Decline in Weaning Rats Is Regulated at the Transcriptional Level and Not Caused by Termination of Milk Ingestion

Abstract

Lactase activity declines during postnatal development in rats, but little is known about the underlying molecular mechanism of this phenomenon. We attempted to clarify whether the regulation was at the transcriptional or post-transcriptional level and to examine the effects of dietary factors on that regulation. Newborn rats were divided into two groups… (More)
