Supplementary information

Pit1 also known as POU1F1 is a transcription factor with a mass of approximately 33 kDa. This protein is involved in the regulation of pituitary-specific genes and is critical for the development and function of the pituitary gland. It expresses mainly in the anterior pituitary where it activates several genes required for pituitary hormone production. Pit1 plays a role in differentiating somatotrophs lactotrophs and thyrotrophs which produce growth hormone prolactin and thyroid-stimulating hormone respectively.
Biological function summary

The Pit1 protein regulates the transcription of genes related to hormonal production in the anterior pituitary gland. It interacts with other transcription factors to form a complex that ensures the precise regulation of target genes. This regulation is essential for normal growth metabolism and reproductive functions. By controlling the expression of growth hormone thyroid-stimulating hormone and prolactin Pit1 directly affects various physiological processes in the body.

Pathways

Pit1 plays a vital role in the growth hormone (GH) and prolactin signaling pathways. It interacts with various regulatory proteins that modulate gene expression within these pathways. In the GH pathway Pit1 collaborates with proteins like GH-releasing hormone receptor to ensure adequate hormone levels in circulation. Additionally within the prolactin pathway Pit1 ensures the proper function of Jak-STAT signaling important for reproductive and metabolic functions. Its activity impacts important pathway components and further affects energy balance and cell proliferation.

Mutations or alterations in the Pit1 gene can lead to combined pituitary hormone deficiency (CPHD). This condition results in impaired hormone production affecting growth and development. Pit1 interacts with proteins like PROP1 which influences pituitary function and contributes to the pathogenesis of CPHD. Another disorder associated with Pit1 is congenital hypothyroidism where thyroid-stimulating hormone production is hindered impacting metabolism and growth. Understanding the role of Pit1 in these conditions can help in developing targeted therapies to manage hormonal disorders effectively.
