Circadian synchronization determines critical day length for seasonal responses.
Delhi, India. In Physiol Behav, 01 Sep 2015
To investigate this, we measured expression levels of genes implicated in the photoperiod-induced changes in reproduction (EYA3, TSH beta, DIO2, DIO3, GNRH and GNIH) and metabolism (SIRT1, HMGCR, FASN and PPAR alpha) in photosensitive redheaded buntings subjected to light-dark cycles of varying period lengths (T-photocycles).
Thyrotropin in teleost fish.
College Station, United States. In Gen Comp Endocrinol, 2009
Descriptive studies have found increased TSHbeta expression associated with life history events thought to be promoted by thyroid hormones.
Basic science and clinical research advances in the pituitary transcription factors: Pit-1 and Prop-1.
Aurora, United States. In Curr Opin Endocrinol Diabetes Obes, 2008
Among these findings include: the effects of the Pit-1 coactivators, GATA-2 and TRAP-220, on the transcriptional regulation of the TSHbeta gene and thyrotropin expression, characterization of a novel pituitary regulator of Pit-1 expression, Atbf1, elucidation of the roles of Wnt and Notch signaling on Prop-1-mediated specification of the Pit-1 cell lineage and gonadotropes, and the identification of regulatory regions of the Prop-1 gene.
[Progress on pituitary-specific transcription factor (POU1F1) in poultry].
Beijing, China. In Yi Chuan, 2004
Prolactin (PRL),Growth Hormone (GH), and Thyroid-stimulating Hormone-beta(TSHbeta), secreting by chicken anterior pituitary, are essential hormones affecting chicken laying ability, growth rate, and immunity via regulating chicken broodiness, development, and immune response.
Genetic Defects in Thyroid Hormone Supply
Madagascar. In Unknown Journal, 0001
This situation can be determined by alterations in genes involved in ontogeny of the thyroid, including PIT1 and PRPO1, HESX1, LHX3, LHX4 and SOX3 as well as by mutation in the TSH-beta or in the immunoglobulin superfamily member 1 (IGSF1) genes.
