19. Pit-1 overexpression or knockdown in human breast cancer cell lines induced profound phenotypic changes in the expression of proteins involved in cell proliferation, apoptosis, and invasion.

20. These results support the inference that W194XProp1 is unable to increase POU1F1 gene expression by the defect of transactivating domain and that S156insTProp1 is unable to increase due to the loss of DNA-binding activity.

8. EKLF increases PIT1 expression during RBC maturation by binding to its promoter in vivo.

9. Results suggested that Pit-1 w could be involved in the paracrine/autocrine system in mice and may be necessary for normal testicular function via its possible role in regulating PRL expression in testicular germ cells.

10. Significant differences in gene expression were noted between each mutant and their normal littermates, as well as between Prop1 and Pit1 mutants.

11. Data indicate that protective alleles of Mtap1a are not sufficient to rescue DW/J-Pou1f1dw/dw mutant hearing.

12. Mouse Pit-1 w plays a role in spermatogenesis. This is the first report demonstrating the expression of Pit-1 variants arising from alternative promoters in mammals.

13. miR-26b regulates Pit-1 expression by inhibiting Lef-1 expression and may promote Pit-1 lineage differentiation during pituitary development.

14. Data show that the PiT-1 embryos displayed anemia, a defect in yolk sac vasculature, and arrested growth, and indicate that PiT-1 has a necessary, nonredundant role in embryonic development.

15. Pit1 mutation may result in physiological homeostasis that favors longevity

16. the Pit1 mutation results in a decreased activity of the insulin/IGF-1 pathway and plays a key role in the longevity of the Snell dwarf mouse

17. multiple domains of Pit-1 are required for full synergy with GATA-2 and sequences between the two binding sites contribute to co-occupancy with both factors on the proximal TSH beta promoter

18. specificity protein-1, PPARgamma, and pituitary protein transcription factor-1 have roles in transcriptional regulation of the murine CORS-26 promoter

19. Down-regulation of protein synthesis may be an important characteristic of the Pit-1 mutation and longevity of the Snell dwarf mouse.

20. The redistribution of co-repressor complexes by Pit-1 might represent an important mechanism by which transcription factors direct changes in cell-specific gene expression.
