Long Non-Coding RNAs Involved in Gynecological Cancer

Abstract

AbstractLong non-coding RNAs (lncRNAs) are defined as transcripts longer than 200 nucleotides with little or no protein-coding capacity. Previously, they were considered transcription byproducts without biological functions. Further studies have shown that lncRNAs are involved in multiple biological and pathological processes, including regulation of epigenetic, transcriptional, and posttranscriptional events. Long non-coding RNA expression patterns in various malignant tumors differ from those of benign tumors and normal tissue, and such alterations may promote or suppress tumorigenesis and cancer progression. The expression profiles of lncRNAs are abnormal in gynecological cancers, such as ovarian cancer, cervical cancer, and endometrial cancer, suggesting an important role for lncRNAs in tumorigenesis/progression of these cancers. Here, we summarized the research progress on identifying the biological functions of lncRNAs in tumorigenesis, progression, and metastasis in gynecological cancers. We provide references for exploring the clinical applications of lncRNAs as early diagnostic biomarkers or ideal therapeutic targets in gynecological cancers.
