“The vasoactive potencies of ADMA (concentration for half-maximal effect with the endothelium intact 25.4 ± 7.1 μmol/l) and L-NMMA (concentration for half-maximal effect with the endothelium intact 8.2 ± 2.9 μmol/l) was significantly (P < 0.05) greater than that of SDMA.”
“These findings reveal the dynamic interplay between different arginine methylation types in the cells, and that the pre-existence of the dominant ADMA mark can block the occurrence of SDMA and MMA marks on the same substrate.”
“The increase in endothelium‐derived ADMA following co‐incubation with l‐NMMA is consistent with competition between ADMA and l‐NMMA for dimethylarginase.”
“These observations provide support for the hypothesis that L-NMMA and ADMA selectively block basal over agonist-stimulated activity of nitric oxide in rat vessels.”
