Colon cancer is the third most frequent cancer in humans. Carica papaya leaves are vegetable foods consumed by most people around the world; it has potential as an anticancer. Therefore it is of interest to investigate the effect of Carica papaya on beta catenin and Wnt mRNA expression in human colon cancer (HT-29) cells in vitro. Human Colon cancer cell line (HT-29) was purchased from the National Centre for Cell Sciences, Pune, India. Cell viability test was done by MTT assay. Gene expression analysis was done by Real Time-PCR. The obtained data were analyzed statistically by one-way analysis of variance and Duncan's multiple range test with Graph Pad Prism version 5 to analyze the significance of individual variations among the control and experimental groups. The significance was considered at p<0.05 level in Duncan's test. Carica papaya caused a marked increase in cell death in a dose dependent manner. At the end of 48 hours, maximum inhibition was at 300 and 400 μg/ml. Carica papaya has significantly reduced the mRNA expression of Wnt and beta catenin (p<0.05). Data showed that Carica papaya leaf extract has anticancer activity on Colon cancer cell lines (HT-29).
