1 ChREBP rather than USF2 regulates glucose stimulation of endogenous L-pyruvate kinase expression in insulin-secreting cells. Glucose MLX interacting protein-like Rattus norvegicus
2 Carbohydrate response element-binding protein (ChREBP) was recently shown to regulate the glucose responsiveness of the L-PK promoter activity in hepatocytes. Glucose MLX interacting protein-like Rattus norvegicus
3 Carbohydrate response element-binding protein (ChREBP) was recently shown to regulate the glucose responsiveness of the L-PK promoter activity in hepatocytes. Glucose MLX interacting protein-like Rattus norvegicus
4 Glucose stimulates ChREBP transcription in INS-1 cells, as shown by nuclear run-on experiments. Glucose MLX interacting protein-like Rattus norvegicus
5 Overexpression of ChREBP in INS-1 cells using the tet-on system results in a left shift of glucose responsiveness of L-PK expression and an enhanced L-PK promoter activity. Glucose MLX interacting protein-like Rattus norvegicus
6 Both endogenous and doxycycline-induced ChREBP proteins bind to the L-PK promoter in a glucose-dependent manner. Glucose MLX interacting protein-like Rattus norvegicus
7 These unprecedented results suggest that ChREBP rather than USF mediates glucose-promoted L-PK expression in insulin-secreting cells. Glucose MLX interacting protein-like Rattus norvegicus
