Endometrial carcinoma (EC) accounts for 20%-30% of female reproductive tumors. Targeted therapy for EC has shown great advantages with small side effects. To improve the survival of EC patients, more new therapeutic targets need to be found. Long non-coding RNAs (lncRNAs) are series of RNAs with over 200 nucleotides that regulate various cellular functions. LncRNA actin filamentin-1 antisense RNA 1 (AFAP1-AS1) is involved in the development of a variety of cancers, such as pancreas ductal adenocarcinoma and esophageal adenocarcinoma. However, it is not clear whether AFAP1-AS1 has any effects on EC or the exact regulatory mechanism. Herein, we found the high expression of AFAP1-AS1 in human EC tissues, and AFAP1-AS1 was correlated with EC patients' prognosis and clinical features. AFAP-AS1 could affect EC cell proliferation, migration, and invasion, and contributed to endothelial cell angiogenesis. We further showed that AFAP-AS1 could promote the expression of VEGFA through the adsorption of miR-545-3p, thus promoting the angiogenesis and invasion of EC, and contribute to tumor growth and metastasis in vivo. Thus, we thought AFAP1-AS1 had the potential to serve as an EC therapeutic target.
