Anti-Cancer Effect of Datura innoxia P. Mill. Leaf Extract in vitro through Induction of Apoptosis in Human Colon Adenocarcinoma and Larynx Cancer Cell Lines

J. Pharmacy Res 01/2010; 3(7):1485-1488.

ABSTRACT Native medicinal plants are traditionally used to prevent and treat a variety of diseases, including cancer. These herbal preparations alleged to have many
biological activities, such as stimulation or suppression of immune responses and antiprolifeative effects on cancer cells. In the present study, we
investigated the effects of methanolic leaf extracts from Datura innoxia, on the growth of human colon adenocarcinoma (HCT 15) and human larynx cancer
cell lines (Hep-2). The methanolic leaf extracts from Datura innoxia potently inhibited growth of both cell lines in a dose dependent manner with IC50 value
300μg/ml and for HCT 15 and Hep-2 cells respectively. The results showed the anti-cancer action is due to nuclear fragmentation and condensation,
associated with the appearance of apoptosis. In addition, Datura innoxia treated HCT 15 and Hep-2 cells had decrease expression of antiapoptotic Bcl-2
protein. These results demonstrated that Datura innoxia inhibits the proliferation of HCT 15 and Hep-2 cells through induction of apoptosis.

    ABSTRACT: The most practical approach to reduce morbidity and mortality of cancer is to delay the process of carcinogenesis by usage of anticancer agents. This necessitates that safer compounds are to be critically examined for anticancer activity especially, those derived from natural sources. A spice commonly found in India and the surrounding regions, is turmeric, derived from the rhizome of Curcuma longa and the major active component is a phytochemical termed curcumin. Green tea is one of the most popular beverages used worldwide, produced from the leaves of evergreen plant Camellia sinensis and the major active ingredients are polyphenolic compounds known as catechins. In this study, synergistic anticancer activity of curcumin and catechin was evaluated in human colon adenocarcinoma HCT 15, HCT 116, and human larynx carcinoma Hep G-2 cell lines. Although, both curcumin or catechin inhibited the growth of above cell lines, interestingly, in combination of both these compounds highest level of growth control was observed. The anticancer activity shown is due to cytotoxicity, nuclear fragmentation as well as condensation, and DNA fragmentation associated with the appearance of apoptosis. These results suggest that curcumin and catechin in combination can inhibit the proliferation of HCT 15, HCT 116, as well as Hep G-2 cells efficiently through induction of apoptosis.

    ABSTRACT: A protein with bioactive potential was purified from the leaves of Datura inoxia The preliminary screening of the crude proteins fractionated by Ammonium Sulphate was carried out for its antibacterial, antioxidant and anticancer properties. It exerted antibacterial activity against three bacteria namely Vibrio cholerae, Staphylococcus aureus, and Escherichia coli but was not effective against Aeromonas hydrophilia. It unveiled an increasing free radical scavenging activity in a dose-dependent manner and presented a potential anticancer activity against human colon adenocarcinoma cell line HT 29. The active protein fraction was purified by ion exchange chromatography on CM-Sephadex. The purified protein has a molecular weight of 14.3 kDa and Peptide Mass Fingerprint using Matrix-Assisted Laser Desorption/Ionization-Time Of Flight Mass Spectroscopy (MALDI-TOF/MS) revealed peptide matches to defensin-like protein of Brassica napus, chaperonin CPN60-2 and mitochondria of Cucurbita maxima. The purified protein showed anticancer activity against HT 29 cancer cell line.

    ABSTRACT: The mycosynthesis approach for nanoparticle synthesis using edible mushrooms is attracting considerable interest over other conventional physical and chemical methods because this approach excludes the use of toxic chemicals. The present study reports the biological synthesis of silver nanoparticles (AgNPs) using an aqueous extract of Pleurotus djamor var. roseus and its cytotoxicity against human prostate carcinoma (PC3) cells. Nanoparticle formation was confirmed by UV–visible (UV–vis) spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. The UV–vis spectrum had an absorption peek at 440 nm, corresponding to the surface plasmon resonance of AgNPs. The TEM image confirmed the nanostructure and spherical shape of AgNPs, with sizes ranging from 5 to 50 nm. The FTIR spectroscopy results showed the binding properties of bio-constituents to identify the possible biomolecules responsible for capping and efficiently stabilizing the nanoparticles. The purity and crystalline structure were confirmed by XRD analysis. Furthermore, the cytotoxicity of biosynthesized AgNPs was evaluated using cell viability and nuclear fragmentation assays. It is evident from the results that the biosynthesized AgNPs inhibited proliferation of PC3 cells with an IC50 of 10 μg/ml during a 24-h incubation. These results suggest that AgNPs may exert their antiproliferative effect on the PC3 cell line by suppressing its growth, reducing DNA synthesis and inducing apoptosis. The morphological analysis of propidium iodide (PI) staining showed the presence of shrunken nuclei, DNA condensation and damage, which revealed cytotoxic effect on PC3 cells by AgNPs.
