RESUMEN
The objective of this study is to examine whether silymarin alone or in combination with chlorogenic acid and/ or melatonin plays a modulatory role against apoptotic damage in rats liver induced by of CCl4. The present work revealed that CCl4 induced elevation of in Bax, Smad, TGF-β and NFkBhepatic mRNA expression, administration of silymarin alone down regulates these expressions. Treatment with chlorogenic acid and/ or melatonin along with silymarin produced best results in this concern. Bcl-2 expression was down regulated by CCl4 whereas concurrent treatment of chlorogenic acid and/ or melatonin along with silymarin increased this expression. On conclusion, the use of chlorogenic acid and/ or melatonin potentiates the anti-apoptotic action of silymarin.
