PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Gene dosage - its misunderstood basis

Denys Wheatley   (2007-04-05 14:52)  Editor in Chief, CCI and TBMM email

Dr Itoh et al's paper, while interesting in its specific detail, has not grasped the basis of gene dosage. I recommend the authors reconsider this basis by consulting two early papers in TBMM (Theoretical Biology and Medical Modelling), which is a BMC journal. The references are to John W Porteous' papers:

TBMM 1, 4, 2004

TBMM 1, 6, 2004

both of which are discussion on the meaning of Mendelian "genetics" (traits) when considered in the light of Kacser's Metabolic Regulation Hypothesis. Gene dosage is best understood only when levels of enzymes (or their products) approach a rate-limiting level within any metabolic (biocheical) pathway.
