ANTIANGIOGENIC EFFECT OF ETHANOLIC EXTRACT OF GREEN ALGAE (Spirogyra sp.) AGAINST EXPRESSION COX-2 IN T47D CELLS

Abstract

Cancer is a group of diseases that arise when a cell or group of cells that regulate out of control growth. Green algae (Spirogyra sp.) is one of the medicinal plants used in traditional medicine for the treatment of cancer. Green algae (Spirogyra sp.) has active substances such as melatonin. Melatonin which is a compound that has been examined by researchers world as anticancer drugs and antioxidants. This study aims to determine the effect of ethanol extract of green algae (Spirogyra sp.) on the expression of COX - 2 in T47D cells. Green algae was extracted using a Soxhlet apparatus with 96 % ethanol. This study used three groups: control cells , ethanol extract of green algae concentrations 247.668 ug / mL and 123.834 mg / mL. To ensure the expression of caspase-3 and Bcl-2, test was conducted using indirect immunocytochemistry. Observations were carried out using a light microscope to see and count the percent expression of COX - 2. The results obtained showed significant difference, decreased expression of COX - 2 in each group. It can be concluded that the ethanol extract of green algae (Spirogyra sp.) decreased COX - 2 expression in T47D cells.
