Serotonin- and Dopamine-Related Gene Expression in db/db Mice Islets and in MIN6 β-Cells Treated with Palmitate and Oleate

Table 1

mRNA expression of energy metabolism-related genes in islets from db/db mice. Total RNA was extracted from a pool of 335 and 312 islets from WT () and db/db () male mice, respectively. Relative mRNA levels of genes related to glucose and lipid metabolism and to mitochondrial function were evaluated by RT-qPCR using custom RT-Profiler. The mRNA levels are expressed as fold-change in of the specific gene in islets from db/db relative to WT mice (see Section 2).
