| 概要 | ||||||
| 値 | Obesity has become one of the major health problems. It is generally accepted that obesity is associated with low-grade systemic inflammation. Previous studies have shown that taste signaling proteins such as G protein gustducin (GNAT3) and phospholipase C, beta 2 (PLCb2) are expressed in the human gut, especially, in intestinal tuft cells, which play a critical role in innate epithelial immunity against parasitic infection. Additionally, it has been shown that taste signaling controls metabolism, including the regulation of body weight and adiposity via intestinal tuft cells and taste cells in mice. This study aimed to determine if gustatory signaling is altered in patients with extreme obesity. The mRNA expression level of PLCb2 and GNAT3 in the proximal discarded jejunum obtained from patients with obesity who underwent bariatric surgery (BMI under 40, 40-49, and 50-59) and was examined using polymerase chain reaction (PCR). After reverse transcript PCR, the intensity of the amplified bands was measured by using imageJ and GAPDH was used as the internal control. Preliminary results of the initial 12 patients were analyzed including with BMI<40, 3 with BMI 40-49, and 5 with BMI 50-59. The intensity of the amplified PLCb2 product from BMI 50-59 patients was lower than those with BMI40-49. The intensity of GNAT3 bands was similar across the three BMI groups. Our preliminary data suggest that gustatory signaling elements may be altered in patients with extreme obesity, and dysregulation of gustatory signaling may contribute to obesity. |
