27016479 PTP1B directly regulates STAT5 phosphorylation and its activation via the cAMP/PKA pathway downstream of the 5-HT7 receptor is involved in the suppression of beta-casein expression in MCF-12A cells
26840794 PTP1B dephosphorylates PITX1 to weaken its protein stability and the transcriptional activity for p120RasGAP gene expression
26721204 Blockade of the interaction between Bcr-Abl and PTB1B by small molecule SBF-1 to overcomes imatinib-resistance of K562 cells.
26402673 O-GlcNAcylation of PTP1B can influence insulin signal transduction by modulating its own phosphatase activity, which participates in the process of hepatic insulin resistance.
26337385 On EGF stimulation, complexes containing Mena and PTP1B are recruited to the EGFR, causing receptor dephosphorylation and leading to decreased motility responses.
26299811 the multiple roles of PTP1B in liver diseases will be presented, with respect to liver regeneration, drug-induced liver disease, non-alcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma--{REVIEW}
26259828 our data indicate that by targeting PTP1B, miR-744 plays a feed-forward role in regulating type I IFN signaling pathway.
25897081 PTP1B inhibited BRK by dephosphorylating Tyr-342, but activated SRC by antagonizing PAG-dependent inhibition by CSK.
25796170 Fumosorinone increased glucose uptake and improved insulin resistance by down-regulating the expression of PTP1B and activating the insulin signaling pathway, suggesting that it may possess antidiabetic properties.
25668475 Data shows a relationship between the dephosphorylation rate of different factors in signaling pathways related to cell proliferation and PTP1B activation.
