Effects of Teaching Thinking Skills on SAT Scores

The study investigated the role of nuclear factor I/B (NFIB) in conjunction with STAT5 in mammary-specific genetic programs during pregnancy. In mice, the absence of both NFIB and STAT5 hindered the formation of functional alveoli, although NFIB alone was not necessary for alveolar expansion. NFIB was found to regulate mammary-specific and STAT5-regulated genes, with evidence of NFIB-STAT5 binding at regulatory elements marked by histone modifications and progesterone receptor binding. The study also identified NFIB-STAT5 modules in hair follicle stem cells, suggesting that these modules, potentially with other transcription factors, govern cell-specific genetic programs across different cell types.
