CXCL12 activates KCNH2. 7 / 9

reach
"Current-voltage relationship of outward of peak tail currents had been shown in Fig. 4 C. SDF-1 (100 ng/ml) significantly increased hERG tail currents."

reach
"Our electrophysiologic results showed that SDF-1 significantly increased hERG tail current, which suggested that SDF-1 enhance functional role of hERG1 K + channels."

reach
"According to our observations, SDF-1 increased hERG current which could engender an increased malignancy of hERG."

reach
"It had beenshowed that inhibition of CXCR4 and SDF -1 axis in AML cells led to reduce proliferation and survival,17 andSDF-1 promoted AML-cell proliferation also by regulating the expression of elastase.19 In light ofthe data presented here, it may be possible that SDF-1 promotes AML-cell proliferation also by regulating the hERG1 Kz channel, which we found to beinvolved in regulation of AML-cell proliferation."

reach
"Berberine may partially inhibit the migration of primary acute myeloid leukemia (AML) cells by reducing the level of SDF-1 protein secreted by bone marrow mesenchymal stem cells in microenvironment and inhibiting HERG1 potassium channel of leukemic cells."

reach
"Moreimportantly, SDF-1 enhanced herg1 gene expression ina dose dependent manner."
