Our objective was to identify the biological response and the cross-talk between liver and mammary tissue after intramammary infection (IMI) with Escherichia coli (E. coli) using RNAseq technology. Sixteen cows were inoculated with live E. coli into one mammary quarter at ~4-6 weeks in lactation. For all cows, biopsies were performed at -144, 12 and 24 h relative to IMI in liver and at 24 h pos...

BILATERAL ligation of the internal mammary arteries was proposed by Fieschi as a simple surgical means of treating patients with coronary artery disease. The procedure aims to increase the blood pressure in the pericardiophrenic branches of the internal mammary arteries and, thereby enhancing coronary anastomoses to the myocardium. Observations made on patients have been conflicting,' as have t...

Knowledge of general aspects of mammary gland function, including metabolic pathways and hormonal regulation of mammary gland development and lactation, in livestock species was obtained several decades ago. As basic biological information of growth factor action, apoptotic mechanisms, and signal transduction events has exploded, the mouse became the model of choice for studying fundamental mec...

The mammary gland performs a variety of immunological functions, including protecting itself from mastitis and protecting neonates from infectious agents. Several molecules that mediate lymphocyte trafficking in the immune system are also expressed in the mammary gland. This review is focused on the immunological function of these molecules, especially glycosylation-dependent cell adhesion mole...

The role of the PEA3 subfamily of Ets transcription factors in breast neoplasia is controversial. Although overexpression of PEA3 (E1AF/ETV4), and of the related factors ERM (ETV5) and ER81 (ETV1), have been observed in human and mouse breast tumors, PEA3 factors have also been ascribed a tumor suppressor function. Here, we utilized the MMTV/Wnt1 mouse strain to further interrogate the role of ...

ABSTRACT: Regular removal of milk from the mammary gland is critical to maintaining milk secretion. Early studies in rodents demonstrated that changes in milking frequency inß uenced mammary blood ß ow, as well as mammary cell number and activity. Later studies in ruminants conÞ rmed those observations and that the response was regulated locally within the mammary gland. In addition, it was dis...

Regular removal of milk from the mammary gland is critical to maintaining milk secretion. Early studies in rodents demonstrated that changes in milking frequency influenced mammary blood flow, as well as mammary cell number and activity. Later studies in ruminants confirmed those observations and that the response was regulated locally within the mammary gland. In addition, it was discovered th...

Sera of C3H/Z/Dm mice bearing spontaneous mam mary tumors, sera of apparently normal C3H/Z/Dm mice at different ages, and a serum of an A/Dm mouse with spontaneous breast cancer were tested by the indirect immunoperoxidase method against cells of C3H/HeJ spon taneous mammary tumor line constantly producing type B or mouse mammary tumor virus particles. The sera were also tested against cells of...

Breast cancer occurs at rate of 1 out of 7. After so many years of research, even though treatment has been dramatically improved and survival rate and length significantly increased, there is still not cure for the disease. The possible existence of mammary gland stem cell and breast cancer stem cell [1, 2] lights the hope for finding a cure to this deadly disease. The rational behind is that ...

This article describes and compares the fat pad clearance procedure developed by DeOme KB et al. and the sparing procedure developed by Brill B et al., followed by the mammary epithelial transplant procedure. The mammary transplant procedure is widely used by mammary biologists because it takes advantage of the fact that significant development of the mammary epithelium doesn't occur until afte...
