Abstract
There are various types of noncoding RNAs in human cells, including microRNA(miRNA), long noncoding RNA(IncRNA), and circular RNA(circRNA). They act as important regulators and exhibit a variety of biological funcions. We studied miRNA biogenesis pathway by removing key factors including Drosha, Exportin 5, and Dicer, Through the genome engineering technique, and compared the role of each protein in miRNA production. We further analyzed the transcription start site of miRNA using Drosha Knockout cell line, and identified transcription factor that may regulate the expression of miRNAs. Because many IncRNAs are expressed in human cells, we also try to indentify the roles of IncRNAs in diverse tissues. Moreover,recent studies suggested that various circRNAs are present in the cells. Because they have miRNA binding sites, we are studying the role of IncRNAs and cicRNAs in gene regulation process. These various types of noncoding RNAs are detected both inside and outside the cells. Especially, many miRNAs exists in human body fluids. Therefore, many studies try to use these miRNAs as molecular markers in diseases. We found that not only miRNAs but also circRNAs are present in blood, and analyzed the blood of leukemia patients to determine whether circRNAs can be used as a diagnostic marker. The studies of various RNAs will give us important insights to understand their roles in biological processes and help us to prevent and treat various diseases.
