KCNQ1 was upregulated in gingival tissues derived from HGF patients and HGF gingival fibroblasts presented increased outward K currents than NHGFs. Overexpression of KCNQ1, or KCNQ1 agonist ML277, promoted fibrotic responses of NHGFs. TGF-β1 and KCNQ1 channels formed a positive feed-back loop. ML277 generated lateral clustering and activation of Ras on plasma membrane, followed by augmented MAPK/AP-1 signaling pathway output. JNK or ERK1/2 inhibitors suppressed ML277-induced AP-1 and ECM upregulation. Activation of KCNQ1 potassium channel promoted fibrogenic responses in NHGFs via Ras/MAPK/AP-1 signaling. Activation of KCNQ1 potassium channel promoted fibrogenic responses in NHGFs via Ras/MAPK/AP-1 signaling. Adherence to the Mediterranean diet (MedDiet) has been reported to be associated with a lower risk of various chronic diseases. This cross-sectional study aimed to investigate the potential association between adherence to the MedDiet and periodontitis, which is highly prevalent in young Moroccan individuals. We evaluated 1075 Moroccan individuals (72% women, mean [standard deviation] age=20.2 [1.5] years). Adherence to the MedDiet was assessed using the MedDiet score (MDS) based on the frequency of intake of eight food groups (vegetables, legumes, fruits, cereals or potatoes, fish, red meat, dairy products, and olive oil). A value of 0 (unhealthy) or 1 (healthy) was assigned to each food group, and the MDS (range, 0-8 points) was generated by adding the individual scores, with a higher score indicating better adherence to the MedDiet. The logistic regression model was used to evaluate the MDS (high [5-8 points]/low [0-4 points]) and each component score (1/0) with the presence of periodontitis, which was determined through full-mouth periodontal examinations. Age, sex, and oral health behavior were considered as poten
