Effects of reduced frequency of milk removal on gene expression in the bovine mammary gland.
Regulation of milk synthesis and secretion is controlled mostly through local (intramammary) mechanisms. To gain insight into the molecular pathways comprising this response, an analysis of mammary gene expression was conducted in 12 lactating cows shifted from twice daily to once daily milking. Tissues were sampled by biopsy from adjacent mammary quarters of these animals during the two milkin...
متن کاملEffects of increased milking frequency on metabolism and mammary cell proliferation in Holstein dairy cows.
Results of previous studies have shown that increased milking frequency (IMF) during early lactation results in increased milk yield not only during the period of IMF but also after cows have returned to a decreased milking frequency. The cellular mechanisms underpinning this increased milk yield and the overall effects of IMF on metabolism have not been well characterized. The objective of thi...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Glucose transporter gene expression in bovine mammary gland.
Transport of glucose across the plasma membrane of mammary epithelial cells is believed to be a passive process of facilitated diffusion mediated by facilitative glucose transporter(s). This article presents three lines of evidence that indicate the expression of sodium/glucose cotransporter (SGLT1) in the mammary gland of lactating and nonlactating cows. First, transcripts of SGLT1 mRNA rangin...
متن کاملGene expression in the mammary gland.
We have demonstrated that the ovine genomic clone SS1 can be used to generate transgenic mice that produce significant quantities of BLG protein in milk. The smallest BLG construct so far examined that retains the ability to direct BLG to mouse milk encompasses approximately 7.3 kb of genomic DNA, of which about 0.8 kb is derived from the promoter region. Gene expression is tissue-specific and ...
