Brassica Oleracea Vegetables Kills Colorectal cancer Cells in Vitro

The colon-rectum formed a part of the digestive system is involved in the absorption of water from the small bowel contents and broken down certain materials in the feces into substances of which some of them to be reabsorbed and reused by the body.

Cancer is a class of diseases characterized by the irregular cell growth on the body tissue, due to the alternation of cell DNA.

Colorectal cancer is a medical condition caused by cell growth irregularly in the tissue of the colon or rectum due to the alternation of cells DNA.

According to the statistics provided by the American Cancer Society, in the US, colorectal cancer is the third most common cancer diagnosed in both men and women compared to other types of cancer.

The lifetime risk of colorectal cancer is 1 in 22 (4.49%) for men and 1 in 24 (4.15%) for women.

Approximately, 140,000 cases of colorectal cancer were diagnosed in the US in 2018. Colorectal Cancer also causes the death of over 50, 000 people, representing 8.3% of total cancer death.

Being overweight or obese. smoking, physical inactivity, excessive alcohol drinking, the increase in age, family and personal history, genetic preposition are some of the prevalent risks of the disease.

Overall, the lifetime risk of colorectal cancer developing is 1 in 22 (4.49%) in men and 1 in 24 (4.15%) in women.

On finding a potential wholefood for the treatment of cancer, researchers examined the effect of principle bioactive compounds, isothiocyanates (ITCs) on a colorectal cancer cell line (HT-29).

According to the chemicals analysis, purple cabbage extract showed the highest ITC concentration per gram, fresh weight, followed by black cabbage and Romanesco cauliflower.

ITC at the concentrations of 7.08 microg/mL decreased cancer cell viability by inducing the caspase-3 associated with cell death and DNA fragmentation at 48h.

Brussels sprouts showed the strongest effects on cell viability and caspase-3 activity. 

Furthermore, all varieties of Brassica Oleracea with rich sources of ITCs potently inhibit the growth of colon cancer cells by inducing apoptosis.

All the extracts showed anticancer activity at ITC concentrations of between 3.54 to 7.08 mug/mL,

Based on the finding, researchers said, " ITC concentration and the chemopreventive responses of plant extracts vary among the varieties of Brassica Oleracea studied and among their cultivars".

Taken altogether, Brassica Oleracea vegetables may be considered functional foods for the prevention and treatment of colorectal cancer, pending to the confirmation of the larger sample size and multicenter human study.
