Abstract:
PURPOSE: A composition containing lysophosphatidic acid(LPA) and adenylyl cyclase(AC) inhibitor is provided to induce cell proliferation of senescent human fibroblasts. CONSTITUTION: A composition for controlling cell senescence contains lysophosphatidic acid(LPA) and adenylyl cyclase(AC) inhibitor as active ingredients. The AC inhibitor is 2',5'-dideoxyadenosine, cis-N-(2-phenylcyclopentyl), azacyclotridec-1-ene-2-amine, or 9-(tetrahydro-2'-furyl)adenine. The effective amount of LPA and AC inhibitor is 1-50 uM and 1-500uM, respectively. The senescent cell is derived from human cells.
