CREM — CRH
Text-mined interactions from Literome
Liu et al., J Neuroendocrinol 2006

The ability of
ICER to
inhibit CRH transcription was examined in the hypothalamic cell line, 4B, which expresses CRH ... Consistent with an inhibitory
effect of
CREM on
CRH transcription, chromatin immunoprecipitation assays in cells transfected with ICER I revealed recruitment of CREM by the CRH promoter in conjunction with decreases in Pol II association

In addition to glucocorticoids, intracellular feedback mechanisms in the CRF neuron, involving induction of repressor forms of
cAMP response element modulator (CREM) limit
CRF transcriptional
responses by competing with the positive regulator, phospho-CREB
Liu et al., Cell Mol Neurobiol 2009
:
To determine whether endogenous
ICER production
represses CRH transcription, we examined the effect of CREM siRNA on forskolin stimulated ICER formation and CRH transcription in the hypothalamic cell line, 4B, and in primary cultures of hypothalamic neurons ... The
role of
ICER on endogenous
CRH expression was studied in primary cultures of hypothalamic neurons by examining the effect of CREM siRNA on forskolin induced primary transcript ( CRH hnRNA ) using intronic real-time PCR
