Objective: Uterine or endometrial cancer affects many women postmenopausal and may reach an advanced stage before signs and symptoms can be noticed. Micro RNAs (miRNAs), non-coding RNAs, play key roles in gene expression regulation and are linked to cancer. This study aimed to elucidate whether some specific types of miRNAs (miRNA133-a, miRNA-21, miRNA-205) can act as prognostic or diagnostic biomarkers for endometrial carcinoma (ER) in Egyptian patients. Methods: Blood samples from 36 patients suffering from endometrial carcinoma and 15 healthy volunteers were tested for expression levels of miRNA 133a-2, 21 and 205. Results: The expression levels of miRNA133a-2, miRNA-21, and miRNA-205 were significantly elevated in ER patients when compared with the control group, the highest levels were noticed in miRNA133a-2. The CA125 levels were significantly higher in all patients as compared with healthy subjects. Conclusion: The findings could support the use of circulating miR133a-2, miR-21 and miR-205 as virtuous prognostic biomarkers for EC in Egyptian patients. The studied miRNA species warrant validation for prospective targeting inhibitory protocols in EC.
