Jasmonates induce apoptosis and cell cycle arrest in non-small cell lung cancer lines.


PMID 17169856

Abstract

The jasmonates, cis-jasmone (CJ) and methyl jasmonate (MJ), were investigated for their effects against NSCLC cell lines A549 and H520. CJ or MJ inhibited the proliferation of both cell lines in a dose-dependent manner as well as induced cell cycle arrest in the G2/M phase. Apoptosis was observed following treatment with CJ or MJ as indicated by Hoechst staining and confirmed by dual annexin V-fluorescein isothiocyanate (FITC)/prodium iodide (PI) and DAPI (4',6-diamidine-2'-phenylindole dihydrochloride) staining. p38 and extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation was observed with increased expression of bax, p21, and caspase-3 activity. These observations indicate that jasmonates may have a therapeutic value in the treatment of lung cancer.
