Abstract:
Matrix metalloproteinases (MMPs), zinc-containing proteinases, play a critical role in tumour progression by degrading extracellular matrix components. MMP2 and MMP9 are secreted from tumour-associated macrophages as well as tumour cells and have been implicated in the formation of the tumour microenvironment. Therefore, the inhibition of these MMPs may suppress tumour progression and metastasis. 4-Hydroperoxy-2-decenoic acid ethyl ester (HPO-DAEE) is known to cause apoptosis in the human lung cancer cell line A549 by inducing endoplasmic reticulum (ER) stress. However, the effects of HPO-DAEE on tumour progression remain unclear. HPO-DAEE pre-treatment significantly suppressed phorbol 12-myristate 13-acetate (TPA)-triggered MMP activation in human monocytic THP-1 cells. It also enhanced the expression of haem oxygenase-1, an antioxidant enzyme, and suppressed the TPA-triggered intracellular accumulation of reactive oxygen species (ROS). Furthermore, HPO-DAEE suppressed transforming growth factor-β1-triggered human prostate cancer PC3 cell migration and this was accompanied by the inhibition of MMP expression and activities. The present results indicate that HPO-DAEE may exert inhibitory effects on tumour progression by suppressing MMP expression and activities.
Insights
4-Hydroperoxy-2-decenoic acid ethyl ester (HPO-DAEE) inhibits matrix metalloproteinases (MMPs) and reduces cancer cell migration. This compound shows potential for suppressing tumor progression and metastasis by targeting MMPs.
Area of Science:
- Biochemistry
- Molecular Biology
- Cancer Research
Background:
- Matrix metalloproteinases (MMPs) are crucial for tumor progression and metastasis by degrading extracellular matrix.
- MMP2 and MMP9 are key players in tumor microenvironment formation.
- 4-Hydroperoxy-2-decenoic acid ethyl ester (HPO-DAEE) induces apoptosis in lung cancer cells via ER stress, but its effect on tumor progression is unknown.
Purpose of the Study:
- To investigate the effects of HPO-DAEE on tumor progression, specifically its impact on MMPs and cancer cell migration.
- To determine if HPO-DAEE can suppress MMP activation and related cellular processes.
Main Methods:
- Assessing MMP activation in THP-1 cells pre-treated with HPO-DAEE and stimulated with TPA.
- Measuring haem oxygenase-1 expression and reactive oxygen species (ROS) levels.
- Evaluating the effect of HPO-DAEE on PC3 prostate cancer cell migration triggered by TGF-β1.
- Analyzing MMP expression and activity in response to HPO-DAEE treatment.
Main Results:
- HPO-DAEE pre-treatment significantly suppressed TPA-induced MMP activation in THP-1 cells.
- HPO-DAEE enhanced haem oxygenase-1 expression and reduced intracellular ROS accumulation.
- HPO-DAEE inhibited TGF-β1-induced migration of PC3 prostate cancer cells.
- These migratory effects were associated with suppressed MMP expression and activity.
Conclusions:
- HPO-DAEE demonstrates inhibitory effects on tumor progression.
- Suppression of MMP expression and activity is a key mechanism by which HPO-DAEE exerts its anti-tumor effects.
- HPO-DAEE holds potential as a therapeutic agent for inhibiting cancer metastasis.
