Broccoli Inhibits the Pancreatic Cancer Cells in Vitro

By Kyle J. Norton


Pancreatic cancer is a chronic condition characterized by cell growth irregularly in the tissues of the pancreas.

Most cases of primary pancreatic cancer start in the cell on the surface of the inner lining of the pancreatic tissue, before penetrating into the deeper layers to form a large and invasive tumor.

At the early stage, patients with pancreatic cancer may be asymptomatic. However, at the later stage, besides the common symptoms shared by all types of cancer such as unintended weight loss, loss of appetite, fatigue and gastrointestinal discomforts, patients with the condition may also experience localized symptoms such as internal bleeding and severe pain due to the oversize tumor which suppresses the nerve cells and blood vessels.

According to statistics, every year, approximately, over 55,000 adults in the United States are diagnosed with pancreatic cancer, accounting for 3% of all cancers and 7% of all cancer deaths.

The survival rate of pancreatic cancer even diagnosed at a very early stage is very low compared to other types of cancer. The 5-year survival rate at stage IA pancreatic cancer is only14%.

Scientists do not know the exact causes of pancreatic cancers, but they do know several risk factors that can make a person more likely to get the disease, including the genetic and acquired genetic mutation of p16 and TP53 and KRAS, BRAF, and DPC4 (SMAD4).

Other prevalent risk factors, including long-term use of tobacco, exposure to certain chemicals, overweight, and obesity, and unpreventable risk factors of family history, gender, the increase of age and ethnicity are associated with the early onset of pancreatic cancer.

The secondary pancreas cancer has been found to be a metastasis from renal cell cancer, lung, colon and breast cancers.

Broccoli is a mustard/cabbage plant, belong to the family Brassicaceae. The veggie has large flower heads, usually green in color and the mass of flower heads surrounded by leaves and evolved from a wild cabbage plant on the continent of Europe.

On finding a potential plant that processes anticarcinogenic activity, researchers examined the effects of sulforaphane (SF) on the pancreatic cancer cell lines.

In established cell lines and a patient tissue array (n = 96), sulforaphane inhibited the expression of miR30a-3p in the induction of cancer cell lines.

Furthermore, miR30a-3p mimics inhibited the luciferase activity of a Cx43 3'-UTR, a tumor suppression.

Moreover, miR30a-3p-overexpressing tumor xenografts had decreased tumor volume and increased gemcitabine sensitivity in pancreatic cell lines.

The study included 16 subjects randomized, into 3-phase crossover dietary trial of standard broccoli, high glucosinolate broccoli, and water.

In patient tissues, a higher expression of miR30a-3p and a lower expression of Cx43 correlated with malignancy.

Based on the evidence, researchers said, "These findings provide new knowledge and suggest sulforaphane as cotreatment for pancreatic cancer".

Taken altogether, the consequences of these results suggest that the broccoli process the potential anti-pancreatic activity, pending to the confirmation of the larger sample size and multicenter human study.
