| Research Abstract |
To study the role of PKC in the mechanism of contraction in cerebral artery, using porcine cerebral artery, following experiments were planned :
1)The eleven PKC isofomis were explored by Western blotting method following SDS-PAGE.
2)It is known that one of small GTP binding protein, RhoA, and its downstream effecor, Rho-kinase (Rock II) participate in the calcium sensitization. The presence of these proteins, distribution were examined by Western blotting.
3)Myosin light chain (MLC) and phosphorylated myosin light chain (p-MLC) were subjected to Western Blotting.
4)Two dimentional electrophoresis, silver staining were applied to detect and quantify the p-MLC/MLC ratio.
The presence of the mechasnism of calcium sensitization through Rho-Rho-kinase pathway was indicated.
The other mechanism of calcium sensitization, the PKC -mediated pathway was also indicated due to the presence of the conventional PKCs, α, βI, βII.
