BACKGROUND Atrazine (ATR), a widely used chlorotriazine herbicide, inhibits a number of endocrine-dependent processes, including gonadotrophin surges and mammary gland development in rats. Chlorotriazine herbicides are rapidly metabolized in plants and animals to form a group of metabolites that are detected both in the environment and in exposed animals. The extent to which these metabolites a...

Everybody is born with the mammary gland. Mammary gland development occurs through various stages throughout embryonic, and stays dormant for males. Although it uncommon, male also gets breast cancer, occasionally. Male cancer accounts approximately 1% of all cases, increasing. When compared other rare diseases, understudied. Typically, treated in same way as female cancer. In this article, asp...

Saturable, high-affinity binding sites for 3,5,3'-triiodo-L-thyronine (T3) were identified in isolated nuclei and solubilized chromatin extracts of mammary glands, spontaneous mammary tumors, and liver from C3H/HeN mice. Receptor concentration in whole mammary gland nuclei (254 fmol/mg DNA) was only about one-half that of mouse liver nuclei (536 fmol/mg DNA), but in molecular weight (55,000) an...

We have previously demonstrated that the transcription factor nuclear factor (NF)1-C2 plays an important role in the mammary gland for the activation of the tumor suppressor gene p53. It also activates the milk genes carboxyl ester lipase and whey acidic protein, implying that NF1-C2 participates both in the establishment of a functional gland and in protection of the gland against tumorigenesi...

Biological characteristics of nodule-like alveolar lesions (NLAL) induced by 7,12-dimethylbenz[a]anthracene (DMBA) in organ culture of whole mammary gland (BALB/c female mice) were assessed after transplantation into gland-free mammary fat pads of syngeneic virgin mice. (i) Tissue-fragment explants from NLAL areas of the gland produced abnormal lobuloalveolar (LA) outgrowths in 3 of 10 fat pads...

Insulin plays an important role in regulating the partitioning of nutrients to the mammary gland, particularly in lactating ruminants fed concentrate-based diets. There is evidence that the nutritional status of the animals might also affect their response to insulin. This is largely untested in early lactating ruminants fed fresh forage. To investigate nutritional effects on insulin response, ...

Saturable, high-affinity binding sites for 3,5,3'-triiodo-u-thyronine (T3) were identified in isolated nuclei and solubilized chromatin extracts of mammary glands, spontaneous mam mary tumors, and liver from C3H/HeN mice. Receptor concen tration in whole mammary gland nuclei (254 fmol/mg DMA) was only about one-half that of mouse liver nuclei (536 fmol/ mg DNA), but in molecular weight (55,000)...
