An in vivo study by Vera-Nuñez et al. (2021) suggested that a water-soluble lectin isolated from seeds of Moringa oleifera (WSMol) treatment was sufficient to decrease the insulin resistance in the T2DM group as well as control non-diabetic group after 3 weeks of WSMol treatment at the dosage of 5 mg/kg. This evidence concerns the gene INS and type 2 diabetes mellitus.
