Abstract
MiRNAs (miRNA) are small RNA molecules that are not to expressed to proteins. Their size is 20–22 nucleotides in length and they are highly conserved molecules among the species. miRNAs are synthesized in the nucleus as a primary miRNA. Primary miRNA is transferred to cytoplasm by Xpo5 protein (exportin-5) and then is processed by Dicer enzyme to a 22-nucleotide-sized long mature miRNA. miRNAs are differentially expressed in different diseases and are released into plasma by normal and tumor tissues during the cell metabolism. Ovarian carcinoma is the deadliest cancer among women. When the disease was diagnosed, the disease usually progressed. Currently, there is no biological marker to detect ovarian carcinoma at an early stage. Furthermore, there is a need for markers that are sensitive to chemotherapy changes and early detection of the disease. Because of this, miRNAs can be detected in plasma and can be used as highly significant biological markers and therapeutic targets for ovarian carcinoma. When the literature of the last 5 years is searched, there are many studies about miRNA and ovarian carcinoma. In this chapter, studies examining the relationship between ovarian carcinoma and miRNA from different angles are summarized under different sections.Keywords
