In the previous study, we demonstrated the involvement of
dual specificity phosphatase 22
(
DUSP22
/
LMW-DSP2
) in regulating the leukemia inhibitory factor/
interleukin-6
/signal transducer and activator of transcription 3-mediated signaling pathway. In this study, we show beta-estradiol (E2)-induced
DUSP22
mRNA expression in estrogen receptor alpha (ERalpha)-positive breast cancer cells, whereas E2-induced phosphorylation and activation of ERalpha was suppressed by overexpression of
DUSP22
but not catalytically inactive mutants. Furthermore, small-interfering RNA-mediated reduction of
DUSP22
expression enhanced ERalpha-mediated transcription and endogenous gene expression. In fact,
DUSP22
associated with ERalpha in vivo and both endogenous proteins interacted in ERalpha-positive breast cancer T47D cells. These results strongly suggest that
DUSP22
acts as a negative regulator of the ERalpha-mediated signaling pathway.
