“…Caco-2BBE cells were washed with sterile phosphate-buffered saline and treated with RIPA buffer containing proteinase inhibitors (Sigma-Aldrich, St. Louis, MO, USA). Cell lysates were prepared and subjected to western blotting as previously described (Moon et al 2022 ; Um et al 2023 ) using antibodies against ChREBP (NB400-13; Novus Biologicals, Centennial, CO, USA), GLUT5 (27571-1-AP; Proteintech, Rosemont, IL, USA), GAPDH (MAB374; Millipore, St. Louis, MO, USA), and TATA-binding protein (TBP) (ab63766; Abcam, Cambridge, UK). To detect nuclear ChREBP, nuclear lysates of Caco-2BBE cells were obtained using the NE-PER™ Nuclear and Cytoplasmic Extraction Reagents Kit (78833; Thermo Fisher Scientific, Carlsbad, CA, USA), according to the manufacturer’s instructions.…”

Glucose transporter 5 (GLUT5), the main fructose transporter in mammals, is primarily responsible for absorbing dietary fructose in the small intestine. The expression of this intestinal gene significantly increases in response to developmental and dietary cues that reach the glucocorticoid receptor and carbohydrate response element-binding protein (ChREBP), respectively. Our study demonstrates that ChREBP is involved in the dexamethasone (Dex)-induced expression of GLUT5 in Caco-2BBE cells and the small intestine of both wild-type and ChREBP-knockout mice. Dex, a glucocorticoid, demonstrated an increase in GLUT5 mRNA levels in a dose- and time-dependent manner. While the overexpression of ChREBP moderately increased GLUT5 expression, its synergistic increase in the presence of Dex was noteworthy, whereas the suppression of ChREBP significantly reduced Dex-induced GLUT5 expression. Dex did not increase ChREBP protein levels but facilitated its nuclear translocation, thereby increasing the activity of the GLUT5 promoter. In vivo experiments conducted on 14-day-old mice pups treated with Dex for three days revealed that only wild-type mice (not ChREBP-knockout mice) exhibited Dex-mediated Glut5 gene induction, which further supports the role of ChREBP in regulating GLUT5 expression. Collectively, our results provide insights into the molecular mechanisms involved in the regulation of GLUT5 expression in response to developmental and dietary signals mediated by glucocorticoids and ChREBP. General significance: The transcription factor ChREBP is important for Dex-mediated Glut5 gene expression in the small intestine.
