Terminalia Catappa Extract (TCE) Reduces Proliferation of Lung and Breast Cancer Cell by Modulating miR-21 and miR-34a Expressions.

BACKGROUND: After cardiovascular illness, cancer is the one of the main and second cause of death in the worldwide. Despite significant advances in this field, low survival, drug resistance, and side effects of chemotherapy remain an unsolved problem. Due to the high mortality rate among cancer patients, finding the new substance to treatment with low side effects is important. Previous studies have been informed that positive effects of herbal medicines on cancer patients, which are very efficient in the treatment of cancer. METHODS: In this study, the antitumor effect of ethanolic Terminalia catappa leaf extract (TCE) on MCF-7, MDA-231, and A549 cell lines was examined. For this reason, the effects of TCE on cell migration, gene expression, and growth were investigated by scratch, test, real-time PCR (qPCR) qPCR, and MTT tests respectively. RESULTS: As a reported by the MTT outcomes, TCE significantly decreased the viability of A549, MCF-7, and MDA-231 cells (P < 0.05).  Moreover, genes expression patterns that are related to proliferation (miR-21, miR-34a), migration (MMP-13, Vimentin), and apoptosis (Cas-3, Cas-8, Cas-9, Bcl-2, Bax) also have changed significantly after treatment with TCE. Also, in the A549 cell line, Bax (p value: 0.029), Cas-9 (p value: 0.00023), miR-34a (p value: 0.031), Bcl-2 (p value: 0.0076), MMP-13 (p value: 0.041), Cas-3 (p value: 0.00051) and in MCF-7 cell line Bax (p value: 0.0004), Cas-3 (p value: 0.0003), Cas-9(p value: 0.037), miR-34a (p value: 0.005), Bcl-2(pvalue:0.0007), mir-21(p value:0.016), MMP-13(p value: 0.011) and in MDA-231 cell line Bax(p value<0.0001), Cas-3(p value: 0.003), Cas-9(p value: 0.0004). mir-34a (p value:0.0019), Bcl-2(p value:0.0023), MMP-13(p value: 0.032) have significantly changed compare to control group. CONCLUSION: The outcomes of this research determined that T. Catappa might be a potential source of antitumor compounds and could be a candidate for further research.

Anticancer Impacts of Terminalia catappa Extract on SW480 Colorectal Neoplasm Cell Line.

PURPOSE: Colorectal cancer (CRC) is one of the most lethal and prevalent cancers throughout the world. Despite the remarkable advance in the field, drug resistance still remains as an unresolved problem in cancer. Hence, finding effective compounds with minimal side effects to fight cancer is of central priority. Herbal products have been traditionally used to prevent and treat a variety of diseases. METHODS: In the present study, the antitumor effect of Terminalia catappa plant ethanolic extract (TCE) was assessed on SW480 CRC model cell line. In this regard, effects of TCE were evaluated on the proliferation, apoptosis, and migration of SW480 cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, Annexin V/PI flow cytometry, and scratch tests, respectively. Furthermore, changes in the expression of genes involved in these events including Bax, Bcl-2, Caspase 3, Caspase 8, Caspase 9, MMP-13, miR-21, and miR-34a were measured by quantitative real-time PCR (qRT-PCR). RESULTS: According to the MTT results, TCE reduced the proliferation of SW480 cells significantly. The flow cytometry test also revealed a notable rate of apoptosis induction after TCE treatment. An inhibitory effect on cell migration was also evident in scratch test. Expression patterns of the assessed genes also changed subsequent to TCE treatment. CONCLUSION: The results of this study indicated that T. catappa could be considered as a potential source of anticancer compounds and a candidate for further investigations.
