In the version of this article originally published, the y axis labels in Fig. 4b,d were incorrect. In Fig. 4b, the unit on the label was (ng mg-1). This should have been (ng/ml). In Fig. 4d, the y axis label was Serum Fst (ng ml-1). It should have been Serum insulin (ng/ml). The errors have been corrected in the HTML and PDF versions of this article.
