ABSTRACT
Kanker kolorektal merupakan keganasan ketiga terbanyak di dunia pada pria dan wanita. Kejadian kanker di Indonesia mencapai 12,8 per 100.000 penduduk usia dewasa, dengan tingkat mortalitas mencapai 9,5% dari kasus kanker. Progresi kanker sangat terkait dengan ekspresi berlebihan COX-2 pada sel kanker kolorektal. Inhibitor COX-2 seperti COXIB dan NSAID memiliki efek kemopreventif, tetapi juga memiliki efek kardiovaskular yang berbahaya. Terdapat herbal yang memiliki aktivitas antikanker, salah satunya adalah tanaman Mahkota Dewa (Phaleria macrocarpa). Efek antikanker berbagai bagian tanaman telah diuji, tetapi penelitian mengenai bagian batang tanaman Mahkota Dewa masih minim. Ekstrak batang Mahkota Dewa (Phaleria macrocarpa) dipersiapkan untuk dimaserasi dalam etanol. Aktivitas antikanker ekstrak etanol Phaleria macrocarpa in-vitro diuji dengan MTT assay pada lini sel kanker kolorektal HCT116. Studi ini juga menilai efek ekstrak etanol Phaleria macrocarpa terhadap penghambatan ekspresi COX-2 pada lini sel kanker kolorektal HCT116 melalui penghitungan nilai H-score dari pewarnaan imunositokimia. Batang Mahkota Dewa (Phaleria macrocarpa) menunjukkan aktivitas antikanker melalui penghambatan pertumbuhan dengan nilai IC50 sebesar 1,327 µg/ml.  Salah satu jalurnya adalah melalui penghambatan ekspresi COX-2 yang ditunjukkan nilai H-score sebesar 173,33 pada pemberian ekstrak dengan dosis 200 ppm. Penelitian ini membuktikan bahwa batang (Phaleria macrocarpa) menghambat pertumbuhan kanker kolorektal, salah satunya melalui penghambatan COX-2.
ABSTRACT
Colorectal cancer is the third most malignancy in the world in men and women. The prevalence of cancer reached 12,8 per 100,000 adult populations, with mortality rate reaching 9,5% from all cancer cases. Cancer progression is strongly associated with excessive expression of COX-2 in colorectal cancer cells. COX-2 inhibitors such as COXIB and NSAID have been proven to have chemopreventive nature, but also have harmful cardiovascular effects. There are herbs that have anticancer activities such as Mahkota Dewa (Phaleria macrocarpa) plant. Various parts of the plant have been researched on its anticancer effect, but research on its bark parts of Mahkota Dewa is still minimal. Ethanol extract from Mahkota Dewa (Phaleria macrocarpa) bark was prepared for maceration in ethanol. Phaleria macrocarpa bark ethanol extract in-vitro anticancer activity was tested with MTT assay on HCT116 colorectal cancer cell line. This study also assessed the effect of ethanol extract of Phaleria macrocarpa bark on inhibition of COX-2 expression in the HCT116 colorectal cancer cell line by counting the H-score from immunocytochemistry staining. Ethanol extract of Mahkota Dewa (Phaleria macrocarpa) bark shows anticancer activity by inhibiting its growth with IC 50 of 1,327 µg/ml. One of the pathways is through inhibition of COX-2 expression, shown from H-score of 173,33 after administration of ethanol extract of Phaleria macrocarpa bark at a dose of 200 ppm. This study shows that Phaleria macrocarpa bark is a colorectal cancer growth inhibitor, one of which is through inhibition of COX-2.
