Golgin A7 family member B (GOLGA7B) is a plausible novel gene associating high glycaemic index diet with acne vulgaris
While the IGF1/FoxO1/mTORC1 signalling pathway is a well-established nutrigenomic link between high glycaemic index (GI)/glycaemic load (GL) diet and acne vulgaris, other signalling pathways remain elusive. Therefore, we aimed to investigate other genes that are involved in the high GI/GL diet-acne...
