Figure 6. GPCTRs and downstream signaling mediator mRNA expression in oral and extra-oral organs is regulated by obesity.

Figure 6

(A) Sweet and bitter taste receptor mRNA expression in tongue of ad libitum wild type and obese (ob/ob and DIO) mice. DIO animals showed reduced T1R2 and T2R118 expression. (B) GPCTR signalling pathway mRNA expression in tongue of ad libitum wild type and obese (ob/ob and DIO) mice. (C) Sweet and bitter taste receptor mRNA expression in duodenum of ad libitum wild type and obese (ob/ob and DIO) mice. T1R3 and T1R2 were downregulated in ob/ob and DIO animals. T2R116, T2R118, T2R104 showed a downregulation only in DIO animals. (D) GPCTR signalling pathway mRNA expression in duodenum of ad libitum wild type and obese (ob/ob and DIO) mice. αTransd was downregulated in obese (ob/ob and DIO) animals, TRPM5 was downregulated in DIO animals. (E) Sweet and bitter taste receptor mRNA expression in trachea of ad libitum wild type and obese (ob/ob and DIO) mice. T2R118 was decreased in DIO animals. (F) GPCTR signalling pathway mRNA expression in trachea of ad libitum wild type and obese (ob/ob and DIO) mice. (G) Sweet and bitter taste receptor mRNA expression in lungs of ad libitum wild type and obese (ob/ob and DIO) mice. T1R3 was upregulated in DIO mice. (H) GPCTR signalling pathway mRNA expression in lungs of ad libitum wild type and obese (ob/ob and DIO) mice. Gα14 was downregulated in obese (ob/ob and DIO) animals. PLCβ2 was upregulated in DIO animals. (I) Sweet and bitter taste receptor mRNA expression in liver of ad libitum wild type and obese (ob/ob and DIO) mice. T1R3 and T1R2 were upregulated in DIO animals, T2R138 was upregulated in ob/ob and DIO animals. J) GPCTR signalling pathway mRNA expression in liver of ad libitum wild type and obese (ob/ob and DIO) mice. Gα14 was upregulated in DIO mice, αTransd was upregulated in ob/ob and DIO mice.
