Proteintech rabbit anti mkp7 antibody

A The relative mRNA levels of <t>MKP7</t> in the islets from WT and KO mice fed with normal diet were assayed with qPCR. B The relative protein level of MKP7 in the islets from WT or KO mice fed with a normal diet was obtained with Western Blotting. After 4 months of high-fat diet feeding, WT and KO mice were tested for the basal blood glucose level ( C ) and GTT ( D ). The relative p-JNK levels and the relative MKP7 levels in the islets from WT or KO mice fed with a high-fat diet for four months were analyzed ( E – F ). These data represented the means of three independent experiments, * P < 0.05, ** P < 0.01, *** P < 0.001 vs. ns. Error bars were shown as SD values.

A Sketch for NR4A1 putative binding site in MKP7 promoter. B A diagram of MKP7 promoters with different lengths was designed for luciferase reporter construction. C The relative luciferase activity of MKP7 promoters with different lengths exhibited in both OV and NC cells. D and E ChIP analysis were exploited to detect the physical association between NR4A1 and the promoter region of MKP7; the exogenous NR4A1-HA expression with adenoviral infection in MIN6 cells was associated with chromatin at some specific DNA sequences, after chromatin immunoprecipitation with anti-HA antibodies, the pulled-down DNA fragments were subjected to PCR analysis with specific pairs of primers. The two putative NR4A1 binding sites (−55 to −50, −1637 to −1632) in the MKP7 promoter regulatory sequence were confirmed with specific PCR amplification. These data represented the means of three independent experiments, ** P < 0.01, *** P < 0.001 vs. ns. Error bars were shown as SD values.

A ROS may result in ER-stress. ROS or/and ER-stress incurs JNK activation. The activated JNK leads to pancreatic β cell apoptosis via mitochondria-dependent or independent pathways. B Acute ROS or ER-stress results in the expression of NR4A1, which in turn enhances the expression of MKP7, while MKP7 is able to abolish partial JNK activation by exerting its phosphatase activity, therefore, largely reduces pancreatic β cell apoptosis. The fate of pancreatic β cells depends on the balance between the availability of NR4A1 or MKP7 and the severity of ROS or ER-stress.
