Abstract:
Colon cancer is a common cause of cancer-related death worldwide. However, the underlying mechanism of tumor progression of colon cancer remains far from being elucidated. In the present study, we report the role of UNBS5162 in colon cancer. UNBS5162 is a naphthalimide that can intercalate into DNA and suppress the expression level of CXCL chemokines. Here, we investigated its effect on cell proliferation, mobility and apoptosis in HCT116 cells, and explored the underlying mechanism. A CCK8 assay revealed that UNBS5162 can block the proliferation of colon cancer cells. Base on a Transwell assay, we showed that cell migration and invasion ability of HCT116 cells are inhibited by UNBS5162. In addition, Annexin V-FITC/PI assay and Western blot analysis were performed to detect whether UNBS5162 could induce cell apoptosis. The results indicated that UNBS5162 increases the number of apoptotic cells remarkably. Furthermore, Western blot analysis demonstrated that UNBS5162 down-regulates the expression level of Bcl2, and up-regulates that of Bax as well as the level of activated Caspase-3. Moreover, we examined the impact of UNBS5162 on PI3K/Akt signaling pathway. UNBS5162 substantially inhibited the phosphorylation of Akt and its downstream effector mTOR, and reduced the expression of p-70. Taken together, these results suggest that UNBS5162 should be considered as a potent therapeutic anticancer agent that targets the PI3K/AKT signaling pathway.
Insights
UNBS5162, a novel naphthalimide, effectively inhibits colon cancer cell proliferation and migration. This compound induces apoptosis by targeting the PI3K/AKT signaling pathway, showing potential as an anticancer therapeutic.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Colon cancer is a leading cause of cancer mortality globally.
- The precise mechanisms driving colon cancer progression are not fully understood.
- Identifying novel therapeutic targets is crucial for effective colon cancer treatment.
Purpose of the Study:
- To investigate the therapeutic potential of UNBS5162 in colon cancer.
- To elucidate the molecular mechanisms underlying UNBS5162's anti-cancer effects.
- To evaluate UNBS5162's impact on colon cancer cell proliferation, migration, invasion, and apoptosis.
Main Methods:
- Cell proliferation was assessed using the CCK8 assay.
- Cell migration and invasion were evaluated via Transwell assays.
- Apoptosis was analyzed using Annexin V-FITC/PI staining and Western blotting for apoptosis-related proteins (Bcl2, Bax, Caspase-3).
- The PI3K/Akt signaling pathway was examined through Western blot analysis of phosphorylated Akt, mTOR, and p-70.
Main Results:
- UNBS5162 significantly inhibited colon cancer cell proliferation.
- UNBS5162 reduced cell migration and invasion capabilities.
- UNBS5162 markedly induced apoptosis by down-regulating Bcl2, up-regulating Bax, and increasing activated Caspase-3 levels.
