Bio‐guided fractionation of (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid from Abelmoschus sagittifolius root as a potent α‐glucosidase inhibitor: An integrated in vitro and in silico study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Abelmoschus sagittifolius stands out as a valuable medicinal source for developing functional food targeting type 2 diabetes. This study investigated the α‐glucosidase inhibitory potential of an active fraction obtained from A. sagittifolius roots (ASR), enriched in (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid (OA), using both enzyme ...

Melanocyte Mitogens Induce Both Melanocyte Chemokinesis and Chemotaxis

Journal of Investigative Dermatology, 1995
It is believed that during repigmentation of vitiligo, inactive melanocytes in the outer root sheath of the hair follicle become activated, proliferate, and migrate into the depigmented skin. However, the mechanisms controlling melanocyte migration remain to be elucidated.

Isolation, culture, and transfection of melanocytes

, 2014
Located in the basal epidermis and hair follicles, melanocytes of the integument are responsible for its coloration through production of melanin pigments. Melanin is produced in lysosomal-like organelles called melanosomes.

Biologic characteristics of cultured human vitiligo melanocytes.

, 1994
BACKGROUND: Vitiligo is a pigmentary disorder of unknown cause characterized by depigmented patches due to destruction of melanocytes. Recently, the inherent cellular defect theory has been discussed.
