Effect of propolis on membrane bound enzymes linked with breast cancer

Abstract

According to estimates from the World Health Organization [WHO], in 2020, 685000 people worldwide died and 2.3 million women were diagnosed with breast cancer. Breast cancer will be the most common cancer in the world by the end of 2020, when 7.8 million women will still be living who had received a diagnosis within the previous five years. The current study was formulated to note the effects of ethanolic extract of Propolis and Withaferin-A on Breast tumor initiation by benzo(a)pyrene [B(a)p], and its effects on ATPase enzyme levels. Na+/ K+-ATPase, Mg2+-ATPase, and calcium ATPase enzyme activities were decreased in the erythrocyte membrane and tissues of breast cancer-bearing animals compared with control groups. The levels of enzyme activities were near normal in Propolis treated animals. It wasapparent that the beneficial effect of Propolis was primarily exerted during the initiation and post-initiation stage of B(a)p-induced breast carcinogenesis. Overall, the data indicated that Propolis has modulating effects when administered intra-peritoneally on breast cancer-bearing animals.
