Hormonal control of plasmin and tissue-type plasminogen activator activity in rat milk during involution of the mammary gland.
We have proposed that growth hormone (GH) and prolactin (PRL) interact to suppress apoptosis in the mammary gland. GH increases insulin-like growth factor-I (IGF-I) synthesis whereas PRL suppresses the production of insulin-like growth factor-binding protein-5 (IGFBP-5) in the epithelial cells, which would otherwise inhibit IGF-mediated cell survival. IGFBP-5 was present in milk from involuting...
متن کاملProteomics data in support of the quantification of the changes of bovine milk proteins during mammary gland involution
Here we provide data from three proteomics techniques; two-dimensional electrophoresis (2-DE) followed by identification of selected spots using PSD MALDI-TOF MS/MS, one-dimensional gel electrophoresis followed by LC-MS/MS analysis of gel slices (GeLC) and dimethyl isotopic labelling of tryptic peptides followed by Orbitrap MS/MS (DML), to quantify the changes in the repertoire of bovine milk p...
متن کاملEstrogen reprograms the activity of neutrophils to foster protumoral microenvironment during mammary involution
Epidemiological studies have indicated increased risk for breast cancer within 10 years of childbirth. Acute inflammation during mammary involution has been suggested to promote this parity-associated breast cancer. We report here that estrogen exacerbates mammary inflammation during involution. Microarray analysis shows that estrogen induces an extensive proinflammatory gene signature in the i...
متن کاملMfge8 is critical for mammary gland remodeling during involution.
Apoptosis is a critical process in normal mammary gland development and the rapid clearance of apoptotic cells prevents tissue injury associated with the release of intracellular antigens from dying cells. Milk fat globule-EGF-factor 8 (Mfge8) is a milk glycoprotein that is abundantly expressed in the mammary gland epithelium and has been shown to facilitate the clearance of apoptotic lymphocyt...
متن کاملRemodeling mechanisms of the mammary gland during involution.
The process of post-lactational regression, or involution, of the mammary gland is a complex event characterised by extensive death of the secretory epithelium coupled with remodelling of the extracellular matrix and adipogenesis to regenerate the fat pad. Associated with these events is an inflammatory cascade and acute phase response. The critical signalling pathways that regulated involution...
