Candidate genes for panhypopituitarism identified by gene expression profiling.
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...
متن کاملMolecular analysis of PROP1, PIT1, HESX1, LHX3, and LHX4 shows high frequency of PROP1 mutations in patients with familial forms of combined pituitary hormone deficiency.
UNLABELLED Combined Pituitary Hormone Deficiency (CPHD) is a prevalent disease in Neuroendocrinology services. The genetic form of CPHD may originate from mutations in pituitary transcription factor (PTF) genes and the pituitary image in these cases may give a clue of what PTF is most probably mutated: defects in LHX4 are usually associated with ectopic posterior pituitary (EPP); defects in LHX...
متن کاملPituitary hypoplasia and respiratory distress syndrome in Prop1 knockout mice.
Mutations in Prophet of PIT1 (Prop1), one of several homeodomain transcription factors that are required for the development of the anterior pituitary gland, are the predominant cause of MPHD (multiple pituitary hormone deficiency) in humans. We show that deletion of Prop1 in mice causes severe pituitary hypoplasia with failure of the entire Pit1 lineage and delayed gonadotrope development. The...

15 صفحه اولMolecular Docking and In Silico Study of Denileukin Diftitox: Comparison of Wild Type With C519S-Mutant
Background: Denileukin diftitox (trade name, Ontak) is the first recombinant immunotoxin (IM), in which the binding domain of diphtheria toxin has been replaced by the amino acid sequence of human interleukin-2 (DT389IL-2) using genetic engineering. Purity, stability, and structural property of the protein are critical factors for the scale-up production of this fusion protein. In this IM, loca...
