Abstract

Skin is the largest organ in the human body, and which protects organism against unfavorable external factors e.g., chemicals, environment pollutants, allergens, microorganisms, and it plays a crucial role in maintaining general homeostasis. It is also an important target of oxidative stress due to the activity of oxygen reactive species (ROS), which are constantly generated in the fibroblasts in response to exogenous or endogenous prooxidant agents. An example of such compound with proved prooxidant activity is Doxorubicin (DOX), which is an effective anticancer agent belongs in anthracycline antibiotic group. Increasingly frequent implementation of various strategies to reduce undesirable DOX side effects was observed. Very promising results come from the combination of DOX with dietary antioxidants from the polyphenol group of compounds, such as cichoric acid (CA) in order to lower oxidative stress level. The aim of this work was to evaluate the influence of CA combined with DOX on the oxidative stress parameters in fibroblasts, which constitute the main cells in human skin. We also wanted to examine anti-apoptotic activity of CA in fibroblasts treated with selected concentrations of DOX. Results obtained from the combination of DOX with CA revealed that CA exhibits cytoprotective activity against DOX-induced damage by lowering oxidative stress level and by inhibiting apoptosis. The present finding may indicate that CA may serve as antioxidative and anti-apoptotic agent, active against DOX-induced damage.

摘要

皮肤是人体最大的器官,它保护机体免受不利的外部因素的侵害,如化学物质、环境污染物、过敏原、微生物等,在维持整体内环境稳定方面起着至关重要的作用。由于氧活性物质(ROS)的活性,皮肤也是氧化应激的重要靶点,ROS 会不断地在成纤维细胞中产生,以响应外源性或内源性的促氧化剂。具有证明的促氧化剂活性的此类化合物的一个例子是阿霉素(DOX),它是一种有效的抗癌药物,属于蒽环类抗生素。人们越来越频繁地实施各种策略来降低 DOX 的不良副作用。从 DOX 与来自多酚类化合物的膳食抗氧化剂(如菊苣酸(CA))结合中获得了非常有前途的结果,以降低氧化应激水平。这项工作的目的是评估 CA 与 DOX 联合使用对构成人类皮肤主要细胞的成纤维细胞的氧化应激参数的影响。我们还想研究 CA 在 DOX 处理的成纤维细胞中抗细胞凋亡的活性。从 DOX 与 CA 的联合结果中发现,CA 通过降低氧化应激水平和抑制细胞凋亡,表现出对 DOX 诱导的损伤的细胞保护活性。这一发现可能表明 CA 可能作为抗氧化剂和抗细胞凋亡剂,对抗 DOX 诱导的损伤。
