Circular RNA expression profiling in diabetic foot ulcers and human normal acute wounds. Circular RNA expression profiling in diabetic foot ulcers and human normal acute wounds

Circular RNA (circRNA) microarray analysis was performed to examine the expression profiles of circRNAs in diabetic foot ulcers (DFU) and in human excisional skin wounds 7 days after injury. Overall design: The wound biopsies were divided into two groups: Control = normal day-7 wounds from healthy donors and Test = DFUs. Microarray analysis was performed using Arraystar human circRNA chip.
