Kaszubska et al., Mol Cell Endocrinol 2002
:
Over-expression of
PTP1B in GT1-7 cells
resulted in a dose dependent decrease in endogenous JAK2 and
STAT3 tyrosine phosphorylation compared with cells transfected with lepR alone
Akasaki et al., J Biol Chem 2006
(Glioma) :
Knockdown of STAT3 by STAT3-small interfering RNA negated the inhibitory effect of PTP inhibitor on troglitazone, indicating that troglitazone uses a STAT3 inactivation mechanism that makes caspase-8/9 activities susceptible to cytotoxic agents in glioma cells and that
PTP1B plays a critical role in the down-regulation of activated
STAT3 , as well as FLIP and Bcl-2
Yuan et al., J Biol Chem 2010
(Breast Neoplasms...) :
Furthermore,
PTPN9 WT expression specifically
impairs EGF induced
STAT3 and STAT5 activation, and inhibits the cell growth in soft agar
Handy et al., Biochem J 2011
(Liver Cirrhosis) :
These results suggest two novel mechanisms whereby adiponectin inhibits hepatic fibrosis : ( i ) by promoting binding of SOCS-3 to Ob-Rb, and ( ii ) by stimulating
PTP1B expression and activity, thus
inhibiting JAK2/STAT3 signalling at multiple points
