Genome-wide analysis of long noncoding RNA expression profile in patients with Marjolin’s ulcer

Marjolin’s Ulcer is an aggressive cutaneous malignancy that typically ensues over a period of time in the post-burned lesions and scars or any other chronic wound. Marjolin’s Ulcer makes up 1.2% of all skin cancers, it is reported that 2% of squamous cell carcinoma and 0.03% of basal cell carcinoma originate in burn scars. Recent studies have shown that long non-coding (lncRNA) plays critical roles in a myriad of biological processes and human diseases,Since the roles of lncRNA in Marjolin’s Ulcer remain unknown,they were investigated in the study.Our findings indicate that the expression profiles of lncRNAs has changed in Marjolin’s Ulcer as compared with normal skin and para-cancerous scar, and may provide novel insight into the molecular mechanism underlying the disease and potential novel diagnostic or therapeutic targets for Marjolin’s Ulcer. Microarray expression profiling of mRNAs and lncRNAs were conducted using RNA extracted from normal skin tissues, para-cancerous scar tissues and Marjolin’s Ulcer tissues in three patients with Marjolin’s ulcer.
