OBJECTIVE: Breast cancer causes death in women. Thymus Caramanicus Jalas (TCJ) as a polyphenolic plant has an antiproliferative effect. Accordingly, this investigation studied the TCJ extract anti-tumor effects in a breast cancer model.
METHODS: Twenty-four female BALB/c mice were used in 4 groups including (1) breast cancer (control); (2), (3) and (4) breast cancer + 100, 300 and 500 mg/kg of TCJ extract (once daily for 20-days after breast tumor induction). The breast tumour was induced by 4T1 cell carcinoma injection. Then tumor size and weight were measured. Tumor necrosis factor-α (TNF-α), nuclear factor κ-B (NF-κB), interleukin-6 (IL-6) as inflammatory markers and also Bcl-2, Bax, cytosolic cytochrome-c, apoptosis-inducing factor, and cleaved caspase-3 as biochemical apoptosis markers were evaluated in tumor tissue with western blotting analysis. Also, malondialdehyde (MDA) concentration, hydrogen peroxidase (H2O2), catalase, glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities were exanimated.
KEY FINDINGS: Treatment with TCJ extract (500 mg/kg) decreased the tumor volume, tumor weight, GPx, SOD, and catalase enzyme activity versus the control group (P < 0.05). Also, TCJ (500 mg/kg) extract increased MDA, H2O2, inflammatory and apoptosis markers versus control (P < 0.05).
CONCLUSIONS: Current study showed that TCJ can induce anti-tumour effects via promoting inflammation, apoptosis, and oxidative stress in breast tumour tissue.
