Objective:
To investigate the effect of goniothalamin on antiproliferation and apoptosis induction in three types of colorectal cancer cells.
Background:
Colorectal cancer is the third of the twentieth most commonly diagnosed cancer. Different types of colorectal cancer cells differ in genotype and characteristics leading to different responses to anticancer drugs. Therefore, finding new anticancer compound for the colorectal cancer cells is necessary.
Material And Method:
Antiproliferative response of goniothalamin on three colorectal cancer cell lines including Colo 205, SW480, and LoVo were determined by MTT assay. The antiproliferative response at different time and dose was also observed. Apoptosis induction by goniothalamin was observed in all three cell-lines via morphological changes and nuclear condensation by Hoechst33342 staining.
Results:
Goniothalamin showed different antiproliferative response on Colo 205, SW480, and Lo Vo cells at the IC50 value is 9.86 ± 0.38 µM, 22.00 ± 4.40 µM, and 65.25 ± 1.85 µM respectively. In addition, the antiproliferative response of goniothalamin was a time- and dose-dependent manner Apoptosis morphological changes and nuclear condensation were clearly observed in Colo 205, SW480 and LoVo cells treated with 10 µM, 25 µM, and 50 µM goniothalamin, respectively.
Conclusion:
Goniothalamin showed antiproliferation and apoptosis induction in colorectal cancer cells with different sensitivity depending on cell type. Investigation of mechanisms underlying apoptosis and its potential use for colorectal cancer treatment should be further studied.
Insights
Goniothalamin effectively inhibits colorectal cancer cell growth and induces apoptosis. Its potency varies across different colorectal cancer cell lines, suggesting tailored therapeutic strategies.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- Colorectal cancer (CRC) is a significant global health concern, ranking as the third most diagnosed cancer.
- Diverse CRC genotypes and characteristics lead to varied responses to existing chemotherapies.
- Novel therapeutic compounds are essential for effective CRC treatment.
Purpose of the Study:
- To evaluate the antiproliferative and apoptosis-inducing effects of goniothalamin on three distinct colorectal cancer cell lines.
- To determine the dose- and time-dependent responses of these cell lines to goniothalamin.
- To assess the potential of goniothalamin as a novel therapeutic agent for colorectal cancer.
Main Methods:
- Utilized MTT assay to quantify the antiproliferative effects of goniothalamin on Colo 205, SW480, and LoVo cell lines.
- Observed morphological changes and nuclear condensation using Hoechst33342 staining to confirm apoptosis induction.
- Investigated the impact of varying goniothalamin concentrations and exposure times on cancer cell viability.
Main Results:
- Goniothalamin demonstrated significant antiproliferative activity, with IC50 values of 9.86 ± 0.38 µM (Colo 205), 22.00 ± 4.40 µM (SW480), and 65.25 ± 1.85 µM (LoVo).
- The antiproliferative effect was confirmed to be both time- and dose-dependent across all tested cell lines.
- Apoptosis induction, evidenced by morphological alterations and nuclear condensation, was observed in all three cell lines at specific goniothalamin concentrations.
Conclusions:
- Goniothalamin exhibits potent antiproliferative and apoptosis-inducing capabilities in colorectal cancer cells.
- The sensitivity of colorectal cancer cells to goniothalamin varies based on cell type.
- Further research into the underlying mechanisms of goniothalamin-induced apoptosis is warranted for its potential clinical application in CRC treatment.
