Context: In the current study, we employed gene-regulatory based approach to underscore the putative mechanism of how components of Moringa oleifera (MO) ethanol extract exert its antisickling effects.

Aims: To evaluate the relationship between mRNA expression profiles of some sickle cell related genes in normal rats.

Methods: Normal Wistar rats were administered with MO at 50 and 100 mg/kg body weight and the positive control group administered with folic acid for 14 days. The bone marrow and kidneys were harvested, followed by RT-PCR to assess the expression of Gardos channel [kccn1, kccn4], antioxidant [CAT, G6PD], and progression of meiosis [p21, p27] genes. Hematological parameters were also analyzed.

Results: A downregulation of the Gardos channel genes (KCNN-4 and KCNN-1) was observed on MO intervention at 100 mg/kg while folic acid showed no significant expression. Significantly (p<0.05), MO intervention increased antioxidant system in sickle cell anemia scenario due to the expression pattern of antioxidant genes analyzed in this study and caused changes in hematological parameters such as PCV, HBC, MCH relative to the control groups.

Conclusions: The study concluded that the administration of the ethanol extract of Moringa oleifera leaf increased blood production, has high antioxidant properties and reduced the expression of the Gardos channel pathway. These are important factors in the management of sickle cell disease and MO could be a candidate of interest in drug development.

Keywords: antioxidant; antisickling; Gardos’ channel; gene expression; Moringa oleifera.



Contexto: En el estudio actual, empleamos un enfoque basado en la regulación de genes para subrayar el mecanismo putativo de cómo los componentes del extracto de etanol de Moringa oleifera (MO) ejercen sus efectos antidrepanocíticas.

Objetivos: Evaluar la relación entre los perfiles de expresión de ARNm de algunos genes relacionados con la anemia falciforme en ratas normales.

Métodos: A ratas Wistar normales se les administró extracto de MO a 50 y 100 mg/kg de peso corporal y al grupo control positivo se le administró ácido fólico durante 14 días. Se recolectaron la médula ósea y los riñones, seguidos de RT-PCR para evaluar la expresión de los genes del canal de Gardos [kccn1, kccn4], antioxidantes [CAT, G6PD] y progresión de la meiosis [p21, p27]. También se analizaron parámetros hematológicos.

Resultados: Se observó una regulación a la baja de los genes del canal Gardos (KCNN-4 y KCNN-1) con la intervención de MO a 100 mg/kg, mientras que el ácido fólico no mostró una expresión significativa. Significativamente (p<0,05), la intervención de MO aumentó el sistema antioxidante en el escenario de anemia de células falciformes debido al patrón de expresión de los genes antioxidantes analizados en este estudio y provocó cambios en los parámetros hematológicos como PCV, HBC, MCH en relación con los grupos de control.

Conclusiones: El estudio concluyó que la administración del extracto etanólico de hoja de Moringa oleifera incrementó la producción de sangre, tiene altas propiedades antioxidantes y redujo la expresión de la vía del canal de Gardos. Estos son factores importantes en el manejo de la enfermedad de células falciformes y MO podría ser un candidato de interés en el desarrollo de fármacos.

Palabras Clave: antidrepanocítica; antioxidante; canal de Gardos; expresión génica; Moringa oleifera.
