摘要: Tudor staphylococcal nuclease (Tudor-SN) is a highly conserved and ubiquitously expressed multifunctional protein, related to multiple diverse cell type- species-specific cellular processes. Studies have shown that Tudor-SN mainly in secretory cells, however knowledge of its role limited. In our previous work, we found the protein level was upregulated nucleus bovine mammary epithelial cells (BMEC). this study, assessed milk synthesis proliferation BMEC. We exploited gene overexpression silencing methods, positively regulates via Stat5a activation. Both amino acids (methionine) estrogen triggered NFκB1 bind promoters Stat5a, enhanced nuclear localization p-Stat5a. Taken together, these results suggest key transcriptional regulation BMEC under stimulation hormones.
