Concentrated freeze-dried Black Raspberry extract may help prevent certain cancers by acting on a combination of genes. In animals exposed to a toxic-cancer causing chemical (the compound was N-nitrosomethylbenzylamine or NMBA for short) over 2,200 genes in the esophagus were affected, “These changes in gene expression correlated with changes in the tissue that included greater cell proliferation (out of control multiplication), marked inflammation, and increased apoptosis (cell death),” explained researcher Dr Gary Stoner. But normal function was restored in 462 genes; a group of them being very important in the cancer fighting business (some of them need to be turned on and some turned off) after supplementation with freeze-dried Black Raspberry Extract, researchers from Ohio State University report.
