Circadian synchronization determines critical day length for seasonal responses.
Delhi, India. In Physiol Behav, 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).
Genetic Defects in Thyroid Hormone Supply
Madagascar. In Unknown Journal, 2015
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.
