Stat5 assumes distinct functions in mammary gland development and mammary tumor formation.
The mammary epithelium comprises luminal and basal cells which originate from multipotent mammary stem cells (MaSCs). They form ductal structures embedded in the mammary fat pad in virgin mice and differentiate during pregnancy into alveoli under the control of hormones and growth factors and the activation of specific transcription factors. Genetic manipulations of embryonic stem cells and the...
متن کاملCDP is a repressor of mouse mammary tumor virus expression in the mammary gland.
Mouse mammary tumor virus (MMTV) transcription is highest in the lactating mammary gland but is detectable in a variety of other tissues. Previous results have shown that MMTV expression is suppressed in lymphoid and other tissues through the binding of the homeodomain-containing repressor special AT-rich binding protein 1 to a negative regulatory element (NRE) in the MMTV long terminal repeat ...
متن کاملPPAR signaling exacerbates mammary gland tumor development
Breast cancer cell lines that express the nuclear peroxisome proliferator-activated receptor (PPAR ) can be prompted to undergo growth arrest and differentiation when treated with synthetic PPAR ligands. To evaluate the therapeutic potential of increased PPAR signaling in vivo, we generated transgenic mice that express a constitutively active form of PPAR in mammary gland. These mice are indist...
متن کاملEvaluation of Ultrasonography and Mammography in Diagnosis of Mammary Gland Tumor in Bitches: Based on Tumor Markers
Objective- This study refers to the role of ultrasonography in the diagnosis of mammary gland tumor in bitches as a complementary diagnostic method and its ultimate goal is to evaluate the results of mammography with the positive results of ultrasonography. Design- Prospective study. Animals- 12 German Shepherd bitches with swollen mass in the mammary gland region (group I) and 12 h...
متن کاملCell proliferation and tumor formation induced by eserine, an acetylcholinesterase inhibitor, in rat mammary gland.
Environmental chemicals may be involved in the etiology of breast cancer. There is substantial evidence that breast cancer risk is associated with prolonged exposure to female hormones. Among these hormonal influences a leading role is attributed to the ovarian hormone estradiol, since breast cancer does not develop in the absence of ovaries. The rat mammary gland has special characteristics th...
