The water extract and the lectin WSMoL from the seeds of Moringa oleifera prevent the hypertension onset by decreasing renal oxidative stress.

Maternal endotoxemia disturbs the intrauterine environment, impairs nephrogenesis, and increases the risk of hypertension and kidney disease in adulthood. Here, it was investigated whether maternal treatment with the water extract of Moringa oleifera seeds (WEMoS) or the water-soluble M. oleifera seed lectin (WSMoL) prevents the oxidative stress induced by lipopolysaccharide (LPS) in pregnant rats, and the renal injury and hypertension in the adult offspring.

Water-soluble lectin (WSMoL) from Moringa oleifera seeds treatment recovers glycemic levels and improves left ventricular ejection fraction on Type-2 Diabetes mice model.

Moringa oleifera, a plant widely used in traditional medicine as well as for water purification, contains a lectin on its seeds named WSMoL which modulates several immune characteristics and has shown cardiac safe properties. Here, we tested the hypothesis that WSMoL is able to recover fasting glucose levels and to improve the cardiac left ventricular (LV) function in a type 2 diabetes mellitus (T2DM) mice model. T2DM was induced in adult C57BL/6 mice by combining a high fat diet and low doses of Streptozotocin.

Novel protein from Labramia bojeri A. DC. seeds homologue to Kunitz-type trypsin inhibitor with lectin-like properties.

This study starts by isolating and characterizing the first protein from Labramia bojeri seeds, which belong to the Sapotaceae family. The purified lectin analyzed by SDS-PAGE with and without beta-mercaptoethanol shows two protein bands (M(r) = 19 and 20 kDa), which cannot be resolved. Protein bands have shown similar characteristics as molecular masses, determined by gel filtration and native gel; N-terminal sequences presented a difference in their isoelectric points.
