Abstract:
OBJECTIVETo observe the effects of Cinnamyl aldehyde (CA) on NIH3T3 cell cycle and explore the possible mechanism further.
METHODFlowcytometry was used for observing cell cycle distribution. Expressions of proliferation cell nuclear antigen (PCNA) and Cyclin D1 protein in NIH3T3 cells were assessed by immunocytochemistry.
RESULTAfter culture with CA for 24 hours, the percentage of populations of S phase was enhanced by 3% (P < 0.05) and cell proliferation index (PrI, S + G2/M) was increased by 3.5% (P < 0.01) , but G2/M phase had no obvious changes. The expressions of Cyclin D1 and PCNA proteins were improved markly by CA compared with controlgroup (P < 0.01).
CONCLUSIONCA could promote more cells in G0/G1 phase into S phase, which may be related to the regulation of the expressions of PCNA and Cyclin D1.
