Background

The genes COL1A1 and COL1A2 encode the pro-alpha 1 and pro-alpha 2 chains of type I collagen, respectively, which is one of the main components of skin dermis. We have previously demonstrated that a circular RNA (a class of recently identified non-coding RNAs that exhibit regulatory potency by sequestering miRNAs like a sponge), which we termed circCOL3A1-859267, is downregulated and regulates type I collagen expression in UVA-exposed human dermal fibroblasts (HDFs). However, the precise mechanisms of circCOL3A1-859267-mediated collagen expression in UVA-irradiated HDFs remain unclear.
