Endocrine and autocrine prolactin (PRL) exerts effects on normal breast and breast cancer cells, and high serum PRL is a poor prognostic factor for colorectal cancer. Here we tested the hypothesis that short isoforms of the PRL receptor (PRLR) in human tissue regulate the actions of PRL in cancer. Using 3' RACE we isolated five splice variants of the human(More)
The mammary glands of pigs share many functional and morphological similarities with the breasts of humans, raising the potential of their utility for research into the mechanisms underlying normal mammary function and breast carcinogenesis. Here we sought to establish a model for the efficient manipulation and transformation of porcine mammary epithelial(More)
Female 129:Stat1-null mice (129S6/SvEvTac-Stat1(tm1Rds) homozygous) uniquely develop estrogen-receptor (ER)-positive mammary tumors. Herein we report that the mammary glands (MG) of these mice have altered growth and development with abnormal terminal end buds alongside defective branching morphogenesis and ductal elongation. We also find that the(More)
