5、le; 1 day after KN-93release, a peak of cells had progressed into S and G2-M. KN-93 also blocks cell growth stimulated by basicfibroblast growth factor, platelet-derived growth factor-BB, and epidermal growth factor in NIH 3T3 fibroblasts1. KN-93 inhibits the H+, K+-ATPase activity but strongly diss

6、ipates the proton gradient formed in thegastric membrane vesicles and reduces the volume of luminal space 2. KN-93 (0.5 M) prevents increasedLV developed pressure during action potential prolongation and early afterdepolarizations. Ca2+-independentCaM kinase activity is increased during early afterd

The culture medium is then removed, and the formazan formed in the reactionis dissolved in 150 L DMSO. The optical density of th

10、e solution is measured at 490 nm using amultifunctional microplate reader.
