演題： Deciphering human functional genome using Massively Parallel Reporter Assays
日時： 2024年10月2日（水）12：00- 13：00
Abstract:
98% of our genome is non-coding, and its function remains largely unknown. The non-coding genome contains a variety of enhancers that play crucial roles in gene regulation. Mutations and variations in enhancers are thought to be a major source of human diseases, individual differences, and evolution.
lentivirus-based massively parallel reporter assay (lentiMPRA), a cutting-edge technology that enables high-throughput functional characterization of enhancers at single-nucleotide resolution by quantifying transcribed barcodes. We have leveraged the lentiMPRA technology to dissect enhancer function in the genome and understand the molecular basis of gene regulation underlying complex biological phenomena, such as cell differentiation, disease and evolution.
In my presentation, I will introduce the lentiMPRA methodology and various applications, and discuss the future direction of functional genomics.
