Antioxidant rich Morus alba leaf extract induces apoptosis in human colon and breast cancer cells by the downregulation of nitric oxide produced by inducible nitric oxide synthase.

TLDR
This is the first report showing the downregulation of iNOS and induction of apoptosis by M. alba extract, capable of inducing cytotoxicity in human colon cancer and breast cancer cells.
Abstract
Morus species had been used widely in the traditional medicines for various diseases. In this study we report the in vitro antiproliferative activity of the methanol extract of Morus alba. The extract is capable of inducing cytotoxicity in human colon cancer (HCT-15) cells (IC(50) = 13.8 μg/ml) and breast cancer (MCF-7) cells (IC(50) = 9.2 μg/ml), resulted in significant morphological changes of the cells, fragmentation of DNA, and caspase-3 activation- characteristics of apoptosis. It downregulated the amount of nitric oxide (NO) produced as a result of inducible nitric oxide (iNOS) activation. The HPLC analysis of the extract showed epicatechin (20%), myricetin (10%), quercetin hydrate (12%), luteolin (12%), and kaempferol (6%) as the major active components and ascorbic acid, gallic acid, pelargonidine, and p-coumaric acid as the minor components. To the best of our knowledge, this is the first report showing the downregulation of iNOS and induction of apoptosis by M. alba extract.

Kaempferol: A Key Emphasis to Its Anticancer Potential

TL;DR: Even though growing evidence supports the use of kaempferol for cancer prevention, further preclinical and clinical investigations using kaEMPferol or kaempFERol-rich foods are of pivotal importance before any public health recommendation or formulation using kaempfol.

Evaluation of a Soluble Tetrazolium/Formazan Assay for Cell Growth and Drug Sensitivity in Culture Using Human and Other Tumor Cell Lines

TL;DR: The new XTT reagent provides for a simplified, in vitro cell growth assay with possible applicability to a variety of problems in cellular pharmacology and biology, but still shares many of the limitations and potential pitfalls of MTT or other tetrazolium-based assays.

Nitric oxide synthase activity in human breast cancer.

TL;DR: Calcium-dependent and -independent NO synthase activity was high in invasive tumours compared with benign or normal tissue, and for invasive ductal carcinomas, NO biosynthesis was significantly greater for grade III compared with grade II tumours.

TL;DR: Data from this study are consistent with the hypothesis that excessive NO production by NOS2 may contribute to the pathogenesis of colon cancer progression at the transition of colon adenoma to carcinoma in situ.
