Abstract

The vegetable Momordica charantia L., (family: Cucurbitaceae) is a scientific name of the plant and its fruit. It is also known by other names, for instance in the USA it is known as Bitter gourd or balsam pear while it’s referred to as the African cucumber in many African countries. M. charantia is believed to posse’s anti-carcinogenic properties and it can modulate its effect via xenobiotic metabolism and oxidative stress. This study was specifically designed to investigate the cellular mechanisms whereby α, β momorcharin an extract of M. charantia can induce cell death with the combination of Cyclophosphamide. Different concentration (200µM - 1000µM) of the α, β momorcharin fruit extract were treated (24 hrs incubation) separately with three different cancer cell lines 1321N1, Gos-3, U87-MG and normal L6 muscle cell line. The results also show that Cyclophosphamide (250 µg) with (1000 µM) of the α, β momorcharin extract of M. charantia, and result in significant decreases in cell viability for each cell line, these effects were additive compared to the individual effect of Cyclophosphamide.

Highlights

  • The water-soluble extract of the M. charantia can significantly reduce blood glucose concentrations in type-1 diabetic rats [1,2]

  • Dose-dependent effects of Cyclophosphamide on cell viability Figure 1 shows the effects of different concentrations (50 - 250 μg) of Cyclophosphamide on the viability of the three different cancer cell lines and on healthy L6 skeletal muscle cell line employed in this study

  • The results show that in all three different cancer cell lines (1321N1, Gos-3, U87-MG), Cyclophosphamide can evoke marked and significant (p < 0.05) decreases in the cell viability compared to untreated cells (100% viability)

Summary

Introduction

The water-soluble extract of the M. charantia can significantly reduce blood glucose concentrations in type-1 diabetic rats [1,2]. Several studies have reported that the water-soluble extract of M. charantia can exert anti-cancerous activity through inhibition of DNA, RNA and cellular protein synthesis [3,4,5,6,7]. In the cytosol of cell, through spontaneous β-elimination, acrolein and phosphoramide mustard evolve [19,20,21]. These are the actual agents responsible for cytotoxic effects and DNA crosslinking [22,23]
