Cordyceps Mushroom: a Potent Anticancer Nutraceutical

The Cordyceps mushrooms have a long history as medicinal fungi. In Traditional Chinese Medicine, Cordyceps have been used to treat several conditions including cancers for thousand of years. Extracts from both mycelium and fruiting bodies of C. sinensis, C. militaris and other Cordyceps species showed significant anticancer activities by various mechanisms such as, modulating immune system and inducing cell apoptosis. Some polysaccharide components and cordycepin (3\u27 -deoxyadenosine) have been isolated from C. sinensis and C. militaris, which acted as potent anticancer components. This review article aims to further elucidate the importance of Cordyceps mushrooms by summarizing the findings of some of the important research works concerning possible mechanism of anticancer activity of this mushroom

Efficiency of improved RAPD and ISSR markers in assessing genetic diversity and relationships in Angelica sinensis (Oliv.) Diels varieties of China

Background: Angelica sinensis is awell-known traditional Chinesemedicinal plant.Weaimed to assess the genetic diversity and relationships in A. sinensis cultivars collected from different locations of China and also some other Angelica species. Results: We employed an improved random amplified polymorphic DNA (RAPD) technique for the amplification of DNAmaterials fromten Angelica cultivars, and the resultswere verified by inter-simple sequence repeat (ISSR) analysis. Twenty six RAPD primers were used for RAPD, and the amplified bands were found highly polymorphic (96%). Each primer amplified 8\u201314 bands with an average of 10.25. The cluster dendrogram showed that the similarity coefficients ranged from 0.41 to 0.92. The similarity coefficients were higher among different cultivars of A. sinensis, and lower among different species. Twenty ISSR primers were used for the amplification, and each primer generated 6\u201310 bands with an average of 7.2 bands per primer. The cluster dendrogram showed that the similarity coefficients ranged from 0.35 to 0.89. Conclusions: This study genetically characterized the Angelica species,whichmight have a significant contribution to the genetic and ecological conservation of this important medicinal plant. Also, this study indicates that the improved RAPD and ISSR analyses are important and potent molecular tools for the study of genetic diversity and authentication of organisms

ANTIOXIDATIVE POTENTIAL OF DURANTA REPENS (LINN.) FRUITS AGAINST H2O2 INDUCED CELL DEATH IN VITRO

The effects of Duranta repens fruits were investigated on H2O2 induced oxidative cell death to evaluate its antioxidative potential in vitro. HEK293T cells were treated with different concentrations [0-1000 µg/ ml] of ethanol extract (E-Ex) and methanol extract (M-Ex) of D. repens for 24h, and then treated with 100 µM H2O2 for 24h. Cell viability, antioxidant parameters of cells, and antioxidant constituents of the extracts were determined. Treatment with limited dose of E-Ex or M-Ex increased the survival rate of H2O2–treated HEK293T cells, however the extra-high dose showed growth inhibitory effect. Treatment with E-Ex or M-Ex protected cellular lipid per-oxidation. In vitro analyses showed the 2,2-diphenyl-1-picrylhydrazyl and H2O2 scavenging activities as well as reducing potential of the extracts. We report here that the limited dose of E-Ex and M-Ex possess antioxidative potential, which can protect H2O2-induced oxidative cell damage

Antioxidant Enzymes and Cancer

Although oxidation is the most common biological and energy producing reaction, oxidative stress is harmful to cell, because the products of oxidation such as free radicals and peroxides damage the cellular components, causing several diseases. Damage in DNA is responsible for cancer formation and progression. However, several enzymes such as superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase etc. act as antioxidants to influence oxidative stress. Polymorphisms in these enzymes are supposed to be associated with DNA damage and subsequently the individual’s risk of cancer susceptibility. This review article aims to further elucidate the relationship between antioxidant enzymes and cancers by summarizing the findings of some of the important study concerning expression levels and genetic polymorphisms of antioxidant enzymes in cancer patients

Anticancer activities of Nigella sativa (Black Cumin)

Nigella sativa has been used as traditional medicine for centuries. The crude oil and thymoquinone (TQ) extracted from its seeds and oil are effective against many diseases like cancer, cardiovascular complications, diabetes, asthma, kidney disease etc. It is effective against cancer in blood system, lung, kidney, liver, prostate, breast, cervix, skin with much safety. The molecular mechanisms behind its anticancer role is still not clearly understood, however, some studies showed that TQ has antioxidant role and improves body\u27s defense system, induces apoptosis and controls Akt pathway. Although the anti-cancer activity of N. sativa components was recognized thousands of years ago but proper scientific research with this important traditional medicine is a history of last 2~3 decades. There are not so many research works done with this important traditional medicine and very few reports exist in the scientific database. In this article, we have summarized the actions of TQ and crude oil of N. sativa against different cancers with their molecular mechanisms. © African Journal of Traditional, Complementary and Alternative Medicines

We aimed to assess the genetic diversity and relationships in A. sinensis cultivars collected from different locations of China and also some other Angelica species. Results: We employed an improved random amplified polymorphic DNA (RAPD) technique for the amplification of DNA materials from ten Angelica cultivars, and the results were verified by inter-simple sequence repeat (ISSR) analysis. Twenty six RAPD primers were used for RAPD, and the amplified bands were found highly polymorphic (96%). Each primer amplified 8–14 bands with an average of 10.25.
