a A snapshot representation of the densitometric evaluation of agarose gel electrophoresis of the RT-PCR analysis of TGR5 gene expression. * represents statistical difference to control (p < 0.05) while # represents statistical difference to diabetic control (p < 0.05). b A snapshot representation of the densitometric evaluation of agarose gel electrophoresis of the RT-PCR analysis of GLP-1 gene expression. * represents statistical difference to control (p < 0.05) while # represents statistical difference to diabetic control (p < 0.05). c A snapshot representation of the densitometric evaluation of agarose gel electrophoresis of the RT-PCR analysis of insulin gene expression. * represents statistical difference to control (p < 0.05) while # represents statistical difference to diabetic control (p < 0.05)
