Alternative promoters control many genes including prolactin (PRL), which in man is expressed at extra-pituitary sites controlled by an alternative promoter located 5.8 Kbp upstream of the pituitary transcription start site. Previous studies using short promoter fragments may be misleading, as the human hPRL genomic locus has many conserved far-upstream regions. To study the function of the alternative promoter, we engineered a bacterial artificial chromosome (BAC) expressing ...

Immuno-modulatory role of prolactin in immune tissues driven by the alternative promoter

Prolactin (PRL) is a hormone mainly produced by the lactotroph cells of the anterior pituitary gland. Besides its pivotal role in reproduction, PRL has also been found to have immuno-modulatory properties. The pituitary is the main source of circulating PRL, however it is also expressed in humans at extra-pituitary sites1. In extra-pituitary tissues, PRL mRNA contains an extra exon (exon 1a), and expression is regulated by an alternative promoter upstream of the pit...
