Curcumin has anticancer effects

Anticancer effect of curcumin inhibits cell growth through miR-21/PTEN/Akt pathway in breast cancer cell

Excerpt from abstract: "Curcumin is a polyphenol extracted from turmeric, which that belongs to the Zingiberaceae family. Curcumin has numerous effects, including anti-inflammatory, antitumor, anti-oxidative and antimicrobial effects. However, the effects of curcumin on human breast cancer cells remain largely unknown. The aim of the present study was to investigate the anticancer effects and the mechanisms by which curcumin affects breast cancer cells. 

The anticancer effect of curcumin on cell viability and cytotoxicity on human breast cancer MCF-7 cells was analyzed using 3-(4,5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H-tetrazolium bromide and lactate dehydrogenase assays, respectively. Cell apoptosis of MCF-7 cells was detected using flow cytometry, 4',6-diamidino-2-phenylindolestaining assay and caspase-3/9 activity kits. Reverse transcription-quantitative polymerase chain reaction was used to analyze microRNA-21 (miR-21) expression in MCF-7 cells. The protein expression of phosphatase and tensin homolog (PTEN) and phospho-protein kinase B (pAkt) was determined by western blot analysis. miR-21 was transfected into MCF-7 cells and the anticancer effect of curcumin on cell viability and the expression of PTEN and pAkt was analyzed. 
 
The present results demonstrated that curcumin inhibited cell viability and induced cytotoxicity of MCF-7 cells in a concentration- and time-dependent manner, by inducing apoptosis and increasing caspase-3/9 activities. In addition, curcumin downregulated miR-21 expression in MCF-7 cells by upregulating the PTEN/Akt signaling pathway. The present study has for the first time, to the best of our knowledge, revealed the anticancer effect of curcumin in suppressing breast cancer cell growth, and has elucidated that the miR-21/PTEN/Akt signaling pathway is a key mechanism for the anticancer effects of curcumin."

My comment: Curcumin is a nice addon to our list of anticancer foods:

- Tomatoes
- Broccoli
- Berries
- Walnuts
- Garlic
- Beans

Curcumin induces apoptosis (programmed cell death), which is controlled by epigenetic mechanisms in cases where something goes wrong in the cell. Most cancers are not just bad luck, instead, we can take care of our epigenomes by eating healthy food and having good life habits. Have a healthy life!

Telegony (microchimerism) is not studied by pseudoscientists because it refutes the theory of evolution http://www.theneonnettle.com/features/1006-study-women-store-dna-from-every-male-they-have-sex-with "A new study by the University of Seattle and the Fred Hutchinson Cancer Research Center has revealed that Women absorb and retain living DNA of every single man they have sex with. When scientists were trying to determine if women who had been pregnant with a son might be more predisposed to diseases usually found in men, then also found in the study that the female brain also absorbs male DNA." "Le Dantec wrote that some farmer told him that once his swine copulated with a boar and their pigs absolutely resembled the father in color. But when the same swine copulated with another boar some pigs of the second farrow still resembled the color of the male pig the swine had copulated first."   http://modernnotion.com/is-telegony-real/ "Scientists believe the phe

Early-stage embryos with abnormalities can still develop into healthy babies http://www.sanger.ac.uk/news/view/early-stage-embryos-abnormalities-can-still-develop-healthy-babies Excerpt: "Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down’s syndrome, suggests new research from the University of Cambridge, the Wellcome Trust Sanger Institute and the University of Leuven, Belgium. In a study published today (29 March) in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing – and in many cases completely fixing – the embryo. Researchers at the Department of Physiology, Development and Neuroscience at Cambridge report a mouse model of aneuploidy, where some cells in the embryo contain an abnormal number of chromosomes. Normally, each cell in the human embryo should contain 23 pairs of chromosomes (22 pairs of chromosomes and one pair of sex chr

Millions Of Novel Genetic Variants Found In 1000 Swedish Individuals https://scienmag.com/millions-of-novel-genetic-variants-found-in-1000-swedish-individuals/ Excerpt: "An extensive exercise to map genetic variation in Sweden has found 33 million genetic variants, 10 million of which are novel. Large-scale DNA sequencing methods were used to analyse the whole genome of 1000 individuals from different parts of the country. The study was led by researchers at Uppsala University, who have published their findings in the European Journal of Human Genetics. "This resource will benefit many national research projects investigating the association between genetic variants and diseases," says Professor Ulf Gyllensten, Uppsala University and SciLifeLab, who has led the project.   The data will also be of immediate use in clinical diagnostics to determine whether a genetic variation in a patient is a cause of disease, or if it is also present among healthy individuals in the popu
