Abstract
Context: Cardiovascular disease is a leading cause of mortality worldwide. Following acute myocardial infarction (AMI), cardiac cells release many cytokines and proteolytic enzymes that regulate the extracellular matrix (ECM), including matrix metalloproteinases (MMPs), tissue inhibitor of metalloproteinases (TIMPs), and phosphorylated microtubule-associated protein 4 (Phospho/pMAP4). Aims: To analyze the role of colchicine in ECM regulation post-ischemic in cell line culture towards MMPs, TIMPs, and pMAP4. Methods: This in vitro experimental study was conducted on the 3T3 fibroblast cell line subjected to hypoxic conditions (CoCl2 treatment) and compared with 3T3 cells experiencing hypoxia/ischemic and colchicine treatment. MMP-1, TIMP-1, and pMAP4 expression were measured using flow cytometry. Data analysis was performed using One-Way ANOVA with a 95% confidence level. Results: Treatment with colchicine in the 3T3 fibroblast cell culture regulated the extracellular matrix by increasing TIMP-1 expression and reducing MMP-1 and pMAP4 expression (p<0.0001) following ischemic conditions induced by CoCl2. Conclusions: Colchicine effectively mitigates ECM degradation by enhancing TIMP-1 expression and inhibiting MMP-1 activity and pMAP4 expression post-ischemic conditions.
