INS — TPO
Text-mined interactions from Literome
Ortiz et al., J Biol Chem 1999
:
The forkhead thyroid-specific transcription factor TTF-2 is the main mediator of thyrotropin and
insulin regulation of
thyroperoxidase (TPO) gene expression
Zarrilli et al., Mol Endocrinol 1990
(Cell Transformation, Neoplastic) :
TPO and TG mRNAs are
regulated by TSH and by insulin-like growth factor I (IGF-I) and/or
insulin
Broqua et al., Biochem Pharmacol 1990
:
Thus,
insulin initially triggered a rise in plasma TRP ( without any change in liver TPO activity ) and then
increased liver
TPO activity whilst plasma TRP returned toward control levels
GĂ©rard et al., Mol Endocrinol 1989
:
In primary cultures, insulin is responsible for the basal level and for a part of forskolin induced TG transcription, whereas
TPO transcription is not
affected by
insulin
Aza-Blanc et al., Mol Endocrinol 1993
:
Insulin also
stimulates TPO promoter activity, but the effect of this hormone is weaker and slower than that of TSH
Nascimento-Saba et al., Braz J Med Biol Res 1998
(Diabetes Mellitus, Experimental...) :
These data suggest that
insulin deficiency first
reduces in vivo
TPO activity during short-term experimental diabetes mellitus
