PIT1 was chosen as a candidate gene to investigate its associations with growth, meat quality and carcass composition traits in the pig. PIT1 is known as the pituitary-specific activator of the growth hormone in several mammals. Furthermore, PIT1 is a positive regulatory factor of prolactin and thyroid-stimulating hormone beta. PIT1 is a member of the POU-domain family of genes and is located o...
Mutations in the transcription factors PROP1 and PIT1 (POU1F1) lead to pituitary hormone deficiency and hypopituitarism in mice and humans. The dysmorphology of developing Prop1 mutant pituitaries readily distinguishes them from those of Pit1 mutants and normal mice. This and other features suggest that Prop1 controls the expression of genes besides Pit1 that are important for pituitary cell mi...
BACKGROUND PiT1 (or SLC20a1) encodes a widely expressed plasma membrane protein functioning as a high-affinity Na(+)-phosphate (Pi) cotransporter. As such, PiT1 is often considered as a ubiquitous supplier of Pi for cellular needs regardless of the lack of experimental data. Although the importance of PiT1 in mineralizing processes have been demonstrated in vitro in osteoblasts, chondrocytes an...
the pituitary-specific transcription factor (pit-1) gene is a candidate gene for growth, carcass and also for milk yield traits. in dairy farm animals, the main goal of the selection is the improvement of milk yield and composition. the genes of milk proteins and hormones are excellent candidate genes for linkage analysis with quantitative trait loci (qtl) because of their biological significan...
Acromegaly is caused by somatotroph cell adenomas (somatotropinomas [ACROs]), which secrete GH. Human and rodent somatotroph cells express the RET receptor. In rodents, when normal somatotrophs are deprived of the RET ligand, GDNF (Glial Cell Derived Neurotrophic Factor), RET is processed intracellularly to induce overexpression of Pit1 [Transcription factor (gene : POUF1) essential for transcr...
The pituitary-specific transcription factor (PIT1) gene is responsible for pituitary development and hormone secreting gene expression in mammals. PIT-1 is studied as a candidate genetic marker for growth, carcass and also for milk yield traits. In dairy farm animals, the principal goal of the selection is the improvement of milk yield and composition. The genes of milk proteins and hormones ar...

Mammalian organogenesis results from the concerted actions of signaling pathways in progenitor cells that induce a hierarchy of regulated transcription factors critical for organ and cell type determination. Here we demonstrate that sustained Notch activity is required for the temporal maintenance of specific cohorts of proliferating progenitors, which underlies the ability to specify late-aris...
PIT1 abnormality is defined as a genetic abnormality in the PIT1 gene that encodes a pituitary specific transcription factor, Pit-1/GHF-1. PIT1 abnormality indicates combined deficiency of thyrotropin (TSH), growth hormone (GH) and prolactin (PRL), and has been reported in several cases. We studied the PIT1 gene in a patient with combined deficiency of TSH, GH and PRL. A novel mutation substitu...
The Pou domain transcription factor Pit-1 is required for lineage determination and cellular commitment processes during mammalian adenohypophysis development. Here we report the cloning and mutational analysis of a pit1 homolog from zebrafish. Compared with mouse, zebrafish pit1 starts to be expressed at a much earlier stage of adenohypophysis development. However, as in the mouse, expression ...
