The invention relates to the identification and the use of compounds which inhibit the expression or activity of micro-RNAs for preventing and/or attenuating ageing.
The invention thus relates to an in vitro method for screening for candidate compounds for preventing and/or attenuating ageing of the skin, comprising the following steps:
a. bringing at least one test compound in contact with a sample of fibroblasts ;
b. measuring the expression or the activity of at least one microRNA chosen from miR-134 and miR-152 in said fibroblasts;
c. selecting the compounds for which an inhibition of at least 20%, preferably at least 30%, preferably at least 40 % of the expression or an inhibition of at least 20%, preferably at least 30%, preferably at least 40 % of the activity of at least one microRNA is measured in the fibroblasts treated in a. compared with the untreated fibroblasts.
本发明涉及鉴定和使用抑制微 RNA 表达或活性的化合物,以防止和/或减轻老化。
因此,本发明涉及一种用于筛选预防和/或减轻皮肤老化的候选化合物的体外方法,包括以下步骤:
a. 使至少一种测试化合物与成纤维细胞样本接触;
b. 测量上述成纤维细胞中至少一种从 miR-134 和 miR-152 中选出的 microRNA 的表达或活性;
c. 挑选出与未处理的成纤维细胞相比,在经过 a. 处理的成纤维细胞中至少一种 microRNA 的表达或活性被抑制至少 20%,最好至少 30%,最好至少 40%的化合物。
