Good Morning! Highlights of today’s digest include several AACR Cancer Research meeting abstracts on microbiome profiling which are promising for development of early detection cancer or treatment-associated-toxicity biomarkers and novel probiotics that can prevent HPV infections-associated cancers and oropharyngeal cancers, development of non-invasive health monitoring tools for endangered humpback whales from East Australia, and re-assemblage of rhizosphere microbiome of medicinal Chinese ginseng or Sanqi. Finally, check out the news about development of a food supplement, expected to be commercialized by 2021 and suggested only to be used as a complementary approach -not a replacement of appropriate dietary habits, that involves a probiotic gut bacterium Akkermansia muciniphila to improve metabolism and metabolic factors in obesity, type II diabetes and inflammatory bowel diseases.
