Increasing evidence shows that miRNAs are involved in the growth and development of hypertrophic scars. However, the specific mechanism of miR-205 is unclear. Here, we investigated the relationship between miR-205, thrombospondin 1 (THBS1) expression, and hypertrophic scars, and showed that miR-205 inhibits cell proliferation and migration and induces apoptosis. Double luciferase analysis, Western blot, and real-time polymerase chain reaction showed that miR-205 downregulates THBS1 expression and activity. Compared to the control group, miR-205 inhibited hypertrophic scar development. Our findings contribute to a better understanding of the miR-205-THBS1 pathway as a promising therapeutic target for reducing hypertrophic scars.
越来越多的证据表明 miRNAs 参与了肥厚性瘢痕的生长和发育。然而,miR-205 的具体机制尚不清楚。在这里,我们研究了 miR-205、血小板反应蛋白 1(THBS1)表达与肥厚性瘢痕之间的关系,并表明 miR-205 抑制细胞增殖和迁移并诱导细胞凋亡。双荧光素酶分析、Western blot 和实时聚合酶链反应表明 miR-205 下调 THBS1 的表达和活性。与对照组相比,miR-205 抑制了肥厚性瘢痕的发展。我们的研究结果有助于更好地理解 miR-205-THBS1 途径作为减少肥厚性瘢痕的有前途的治疗靶点。
