Abstract

Breast cancer is the most frequent cancer among women worldwide. Gorgonian Isis hippuris is a marine organism which its secondary metabolites demonstrate anticancer activity in vitro. AgNOR count method, which represents proliferative activity and histological grading score was chosen to measure its anticancer activity. The aim of this study was to investigate the effects of Isis hippuris extract on adenocarcinoma mammae cells in C3H mice. This experimental study used posttest only control group design. Twenty C3H mice were randomized into three treatment groups (T1, T2 and T3) which received 500 mg pellets containing 0.15, 1.5, and 15 mg Isis hippuris extract respectively. The control group (C) received no treatment. Mice were inoculated with adenocarcinoma mammae on the third week, and followed by the treatments for the next three weeks. Afterwards mice were terminated and operated to remove their tumors. AgNOR count method was performed on tumor sections using two parameters, mean of AgNOR (mAgNOR) and percentage of AgNOR (pAgNOR). Histological grading was determined based on Elston and Ellis modification of the Scarff-Bloom-Richardson. Significant differences among four groups were found in mAgNOR (p=.000), pAgNOR (p=.003), and histological grading (p=.008). mAgNOR, pAgNOR, and histological grading of T1, T2 and T3 groups were significantly lower than C group (p≤.05). mAgNOR and pAgNOR of T3 were also significantly lower than T1 and T2. No significant differences were found in mAgNOR and pAgNOR between T1 and T2 as well as in histological grading of all treatment groups (p>.05). This study provide evidence that Gorgonia Isis hippuris extracts can reduce proliferative activity and histological grading of adenocarcinoma mammae cells in C3H mice.
