Abstract
Brusein-A diduga menyebabkan apoptosis. Salah satu protein yang berperan dalam proses apoptosis adalah caspase-3 . Penelitian ini bertujuan mengetahui aktivitas antikanker brusein-A terhadap ekspresi caspase-3 pada kanker payudara. Penelitian menggunakan rancang acak lengkap. Sebanyak 27 ekor tikus betina berumur 12 minggu diberi dimethylbenzanthracene (DMBA) 20 mg/kgBB per oral selama 3 minggu sampai terbentuk kanker payudara. Selanjutnya, dibagi dalam 9 kelompok perlakuan brusein-A, yaitu 0; 2,5; 5; 7,5; 10; 12,5; 15; 17,5; dan 20 mg/L selama 28 hari. Parameter yang diukur adalah ekspresi caspase-3 yang dinilai berdasar atas persentase sitoplasma yang berwarna coklat. Penelitian ini dilakukan di Laboratorium Patologi-Anatomi dan Laboratorium Biokimia, Pusat Penelitian Ilmu Pengetahuan dan Teknologi (Puspiptek) Serpong tahun 2015–2016. Hasil penelitian menunjukkan ekspresi caspase-3 rata-rata pada dosis 0 mg/L sebesar 4%, 2,5 mg/L sebesar 15,3%, 5 mg/L sebesar 21%, 7,5 mg/L sebesar 25%, 10 mg/L sebesar 41%, 12,5 mg/L sebesar 65%, 15 mg/L sebesar 75,3%, 17,5 mg/L sebesar 84%, dan 20 mg/L sebesar 94,7%. Hasil uji one way ANOVA menunjukkan perbedaan ekspresi caspase-3 rata-rata yang signifikan antarkelompok perlakuan (p=0,0001). Uji korelasi Spearman menunjukkan hubungan yang sangat erat dan positif antara dosis brusein-A dan ekspresi caspase-3 (r=0,994). Simpulan, brusein-A meningkatkan ekpresi caspase-3 pada kanker payudara tikus yang diinduksi DMBA.
