Possible involvement of prolactin in the synthesis of lactoferrin in bovine mammary epithelial cells.

چکیده
Bovine mammary epithelial cells (bMECs) synthesize lactoferrin, which is secreted into milk. Our results suggest that prolactin stimulated secretion of lactoferrin in primary bMECs and their clonal cell line under serum-free conditions. Prolactin also stimulated mRNA expression of lactoferrin in the clonal cell line. This effect was reduced by AG-490, suggesting that the prolactin-stimulated mRNA expression of lactoferrin was mediated by Janus kinase (JAK)2.

Interaction of primary mammary bovine epithelial cells with biofilm-forming staphylococci associated with subclinical bovine mastitis
Background: Staphylococci are recognized worldwide as one of the most important etiological agents of bovine mastitis due to their virulence factors such as their ability to penetrate inside mammary epithelial cells and their ability to form biofilm. Aims: The objectives of this study were to establish a model of primary mammary epithelial cells origin...
متن کاملmiR-214 regulates lactoferrin expression and pro-apoptotic function in mammary epithelial cells.
Lactoferrin (Lf) is an abundantly expressed protein in human milk. Lactoferrin exhibits several important biological functions, and its expression is regulated by multiple environmental factors. Cellular endogenous factors, however, have not been extensively studied with regard to lactoferrin gene expression. In this study, we showed that lactoferrin gene expression and function are directly ta...
متن کاملRole of extracellular matrix and prolactin in functional differentiation of bovine BME-UV1 mammary epithelial cells.
Interactions between extracellular matrix (ECM) and epithelial cells are necessary for proper organisation and function of the epithelium. In the present study we show that bovine mammary epithelial cell line BME-UV1 cultured on ECM components, commercially available as Matrigel, constitutes a good model for studying mechanisms controlling functional differentiation of the bovine mammary gland....

Primary cultures of bovine mammary secretory epithelial cells and spontaneously transformed mammary secretory epithelial cells were treated with estradiol 17-ß or prolactin separately and in combination with both hormones. Both estradiol and prolactin induced BRCA1 expression in the cells. Hormone induced expression of BRCA1 was highest in transformed cells. Moreover, the induction of BRCA1 gen...

Background: Lactoferrin (Lf) is a glycoprotein, a member of the transferrin family.From ten known mechanisms of anti-cancer chemoperotecive compounds, Lf alone, has six of these functions and inhibits cancer. In this study, the effect of lactoferrin purified from bovine colostrum was studied as an anti-cancer agent on esophageal cancer cell line. Materials and Methods: Bovine colostrum were ...
