PRIMARY outcome

Timeframe: PKC-zeta mRNA levels and aPKC activity in muscle evaluated 40 minutes post-insulin treatment

Population: PKC-zeta mRNA and aPKC activity in vastus lateralis skeletal muscle was measured by analysis of gene expression levels of PKC and measuring them in relative amounts in comparison to control subjects.

All muscle samples obtained by 9/30/07, final date for examination of samples 9/30/08 Muscle dependent ability to diminish blood glucose levels during insulin treatment.
