Abstract :

Mammary gland tumors arethe most common type of cancer in dogs and cats after skin tumors. Any disorder in the process of apoptosis causes the growth of cancer cells. Caspases 3 and 9 play an important role in the process of apoptosis as initiator and executioner caspases. This study was conducted to investigate the effect of Tilia (Tilia plathyphyllos) extract on gene expression of caspase 3 and caspase 9 in canine mammary gland cancer cell line. Canine mammary gland tumor cells (CF41.Mg) were passaged in the presence of 5, 10, 25, 50 and 100 mg/ml of Tilia extract for 24, 48 and 72 hours. Microculture tetrajolium test (MTT) was used after the passage to assay the number of live cells. To understand the mechanisms involved in induction of cell death at previously mentioned intervals, RNA was extracted and cDNA synthetizedand the rate of gene expression of caspase 3 and 9 was evaluated using specific primers with RT-PCR. According to the result, maximum  anti-tumor activity of this extract was observed after 48 hours with the  dose of 25 mg/ml. RT-PCR results indicated gene expression of caspase 3 and 9 after 24, 48 and 72 hours in the treated samples. The highest extent of gene expression was observed at 10 and 100 mg/ml of extract for caspase 3 and 10 mg/ml of extract for caspase 9. The results of the present study confirmed the inhibitory effects of Tilia extract on growth of canine mammary gland tumor cell line.
