Gene Genie #20

gene-genieHere at Bitesize Bio we are very proud to have the chance to host our first ever blog carnival. Gene Genie brings together blog articles from an array of perspectives within the area of human genes, genetics and diseases. It has been a pleasure and an education reading through all of these great articles and I’d like to thank all of the authors for contributing, and Gene Genie founder Berci Mesko for allowing us to host the carnival. So lets get to the articles….

There was much baby talk around the blogs. Breastfeeding & IQ & norm of reaction at the Gene Expression blog highlighted a study that showed breast-fed infants with one variant of the FADS2 gene, a regulator of fatty acid pathways, benefited from an improved IQ compared to formula-fed infants. Hsien-Hsien Lei took this one step further at Eye on DNA, exhaulting the old.jpgknown health benefits of breastfeeding, genetically influenced or otherwise. Also on the subject of babies, Hsien-Hsien highlighted the clash between recently passed genetic privacy laws and Newborn Genetic Screening in Minnesota.

While those bloggers focused on the young, others were interested in what makes us become old. Charles Daney at Science and Reason, reviewed the history of Leonard Guarente’s work into the links between SIR genes, calorific intake and aging in yeast and, here at Bitesize Bio, Dan highlighted evidence from C.elegans implicating the Insulin/IGF-1 receptor signaling pathway in the regulation of genes involved in aging and cancer.

Lee from DNA Direct Talk cautioned that there’s more to race than DNA, a Gene Expression article examined further determined attempts to identify the gay gene and John Fossella mused on the role of his wife’s seratonin receptors in prolonging the tedium of selecting new paint colors in How my wife’s colorblind synesthesia (or HTR2A gene) drove me up a wall at OriginsGenomeResources. I can relate John.

Finally, The Genetic Geneologist examined the potential size of the genetic testing market.

  • Gene Sherpa Steve Murphy reported on promising results from a pharmacogenetic-guided Warfarin dosing study.
  • Keith Robinson at Omics! Omics! described a newly-developed system for measuring the levels of VEGF receptors to assist with accurate dosing of anti-VEGF drugs.

Don’t forget to check out the next edition of Gene Genie, which will be hosted on December 2 at the excellent Bayblab blog… and finally, thanks to Ricardo at My Biotech Life for designing the Gene Genie logo.
