  1. Analysis of mRNA expression in islets of Langerhans isolated from control db/db mice and db/db mice receiving dietary supplementation with 1% (w/w) EGCG or 0.0021% (w/w) rosiglitazone (Rosi) for 10 weeks. The mRNA levels of the indicated genes were normalized to the levels of β-actin mRNA and expressed as mean percent ± SEM of the control group, n = 4. * denotes P < 0.05 for a chance difference vs controls and # denotes P < 0.05 for a chance difference vs palmitate using one-way ANOVA. MIN6 cells were exposed in vitro for 48 hrs to EGCG (20 μM), palmitate (0.5 mM) or a combination thereof
