Similarity of GATA-3 Expression between Rat and Human Mammary Glands
نویسندگان
چکیده
The GATA family members are zinc finger transcription factors involved in cell differentiation and proliferation. In particular, GATA-3 is necessary for mammary gland maturation and is a useful marker in the characterization of mammary carcinoma in humans. The expression of GATA-3 protein in normal mammary glands, fibroadenomas and carcinomas was immunohistochemically compared in female rats and humans. In normal mammary glands of rats and humans, scattered luminal cells in the acini and whole ductal epithelial cells were positive for GATA-3 in the nuclei. No positive cells were detected in rat or human fibroadenomas. In rat and human mammary carcinomas, the nuclei of proliferating luminal-derived cancer cells expressed GATA-3. Therefore, GATA-3 protein is a candidate marker for mammary carcinoma in rats as well as humans.

متن کاملThe Stat6-regulated KRAB domain zinc finger protein Zfp157 regulates the balance of lineages in mammary glands and compensates for loss of Gata-3.
Lineage commitment studies in mammary glands have focused on identifying cell populations that display stem or progenitor properties. However, the mechanisms that control cell fate have been incompletely explored. Herein we show that zinc finger protein 157 (Zfp157) is required to establish the balance between luminal alveolar pStat5- and Gata-3-expressing cells in the murine mammary gland. Usi...

There are different challenges regarding management of these cancers in dogs and human, one hypothesis is related to small cellular subset of tumor mass called cancer stem cell. These cells are therapy resistant and cause metastasis and relapse even after primary successful treatment. The well-identified phenot...
