Growth inhibitory effect of Leptospermum scoparium (manuka) chloroform extract on breast and liver cancer cell lines
Mohammed Al-Zharani
Objective: Research has demonstrated that Leptospermum scoparium possesses various thera¬peutic benefits. This study set out to determine whether or not L. scoparium extracts had any effect on the ability of HepG2 and MCF-7 breast cancer cells to survive. Materials and Methods: The antiproliferative activity of L. scoparium extracts was explored using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and lactate dehydrogenase assays. The most active fraction was selected to investigate its effects on apoptosis induction using flow cytometry and quantitative real-time polymerase chain reaction. The constituents of this fraction were characterized using GC-MS analysis. Results: Research demonstrated that the chloroform fraction of L. scoparium (LSCF) significantly impacted the HepG2 and MCF-7 cancer cell lines. Treatment with LSCF led to a notable rise in both early and late apoptotic cells. Furthermore, there was an upregulation in the mRNA levels of P53, Bax, and caspases, while the expression of Bcl-2 mRNA saw a decrease. The analysis of LSCF revealed the primary components to be cis-calamenene, beta-eudesmol, cyclododecane, and alpha-muurolene. Conclusion: The study showed the promising antiproliferative activity of L. scoparium, suggesting its potential application for cancer treatment. [J Adv Vet Anim Res 2024; 11(2.000): 237-246]
