Pinto Bean's Lectin, the Anti Cancer Cell Proliferative Antioxidant

By Kyle J. Norton

Proliferation is a process of cancer growth associated with an abnormally high rate of cancer cell division, leading to rapid overgrowth of the tumor.

Cancer is the class of diseases associated with the growth of the cells disorderly and uncontrollably due to the alternation of DNA.

According to the statistics provided by the American cancer society, in 2018,1,735,350 new cases were diagnosed, representing more than 4,700 new cancer diagnoses each day.

The lifetime probability of being diagnosed with cancer is 39.7% for men and 37.6% for women.

Cancer cell proliferation by dividing unlimitedly, compared to normal cells that die after a certain cell cycle division.

More precisely,
* The growth of normal cells
Under normal circumstances, cell growth is a natural process without even notice, every day millions of cells grow to replace millions of dead cells and to keep our body in balance and healthy.

Sometimes, acceleration of cell growth is necessary to prevent further damage to the body organ, such as cut, injure, etc., but after fulfilling their purposes, the growth of cells is back to a normal rate again due to our body growth inhibitors. 

Unfortunately, skin cells sometimes overgrow while healing, leading to scar to the skin.


*The primary tumor; size and growth
A primary tumor or original tumor that the tumor progression that yields a cancerous mass. 

Some cancers can begin in several places, such as lymphomas and leukemias. Most cancers can not be detected until they formed a small grape-like lump. 

Cancer cells need 42 doublings before it can produce enough cancer cells to cause death.

According to the statistics provided by the National Cancer Institute, In 2018, approximately 1,735,350 cases of cancer were diagnosed in the US and the disease also caused the death of 609,640 Americans.

On finding a natural ingredient for the prevention and treatment of cancers, scientists examined the antiproliferative effects of Lectins (hemagglutinins) from the common edible bean Phaseolus vulgaris cv. Hokkaido large pinto bean.

Pinto bean is also known as common bean, genus Phaseolus and the family Fabaceae. It has a mottled appearance of darker reddish-brown spots on a lighter brownish beige background, thus appearing painted or spotted.

According to the tested analysis of a 60 kDa dimeric hemagglutinin with a blocked N-terminus was isolated in large yield (190 mg/60 g) from the pinto beans,
* The administration of 60 kDa showed an inhibitory proliferation of nasopharyngeal carcinoma (CNE2), human breast cancer (MCF7), and hepatoma (HepG2) cells.

* The IC50 values were considered relatively low among lectins of different P. vulgaris cultivars toward HepG2, MCF7, and CNE2 cells after treatment for 48 h were 8.1, 6.07, and 7.49 μM, respectively,

In other words, the lectin found in the pinto bean as sugar-binding proteins or glycoproteins with various biological activities exerted a promising remedy for the treatment of cancers in vitro.

Taken altogether, Pinto beans may be considered a promising anti proliferative functional food, pending to the confirmation of the larger sample size and multicenter human study.
