概括

用KY19382阻断CXXC5,通过促进纤维细胞激活和血管化,增强了糖尿病小鼠的伤口愈合. 这项研究确定CXXC5是慢性伤口修复的关键调节者.

科学领域:

细胞生物学细胞生物学
分子生物学分子生物学
再生医学是一种再生医学.

背景情况:

细胞外基质 (ECM) 和血管生成对于伤口再生至关重要,但它们的功能障碍会影响糖尿病的愈合.
CXXC5是CXXC蛋白家族的一员,影响人类皮肤纤维细胞 (HDF) 和人类静脉内皮细胞 (HUVEC),但其在伤口愈合中的确切作用尚不清楚.

研究的目的:

研究CXXC5在糖尿病伤口愈合中的作用.
评估使用KY19382在糖尿病伤口模型中准CXXC5的治疗潜力.

主要方法:

糖尿病和对照小鼠被用KY19382或车辆治疗.
在体外研究中,在不同的CXXC5条件下刺激HDF和HUVEC.
试验包括西式涂抹,免疫光和qRT-PCR来分析分子信号和伤口愈合参数.

主要成果:

与对照组相比,糖尿病小鼠表现出受损的伤口愈合,减少血管化和原干扰.
在高葡萄糖和糖尿病条件下,KY19382治疗通过增强纤维细胞激活和血管化来改善伤口愈合.
从机制上讲,阻断CXXC5稳定了Wnt/β-catenin信号传输,通过VEGFA/VEGFR2和NFκB通路促进了HUVEC管的形成和迁移,并通过阻断CTBP1转录增强了HUVEC的激活.

结论:

CXXC5是伤口愈合过程的关键调节者.
用KY19382准CXXC5显示为治疗慢性糖尿病伤口的治疗策略.

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Phases of Wound Repair

Phases of Wound Repair

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...
