Project description:SELEX (systematic evolution of ligands by exponential enrichment) and RNA Immunoprecipitation (RIP)-seq revealed that CIRBP directly binds the 3’UTR of Atp5g3.
Project description:SELEX (systematic evolution of ligands by exponential enrichment), chromatin immunoprecipitation (ChIP)-seq, and crosslinking immunoprecipitation (CLIP)-seq showed that the DDX43 KH domain binds C/T rich DNA and U rich RNA.
Project description:To identify the directly bound transcripts of Flag antibody (the backgroud control for our METTL16 RIP-seq), RNA immunoprecipitation sequencing (RIP-seq) was conducted HEK293T. Briefly, HEK293T cells were infected with pmiRNA1-empty vector. Only the GFP-positive cells were used for study and expanded in DMEM medium.
Project description:Type 1 Diabetes is still an incurable disease characterized by autoimmune destruction of insulin-producing beta cells within the islet of Langerhans in the pancreas. Currently, there are no methods to monitor beta-cell mass in humans or deliver therapeutics specifically to beta cells. Here we performed Cluster Systematic Evolution of Ligands by Exponential Enrichment (SELEX) experiments and toggle SELEX experiments to identify RNA aptamers specific for human islets. In the cluster SELEX, we started from a random library of RNA nucleotides composed of a 40 nucleotide long variable region flanked by two constant regions. We performed eight selection cycles using hand-picked islets and islet-depleted acinar tissue from 4 cadaveric human donors as positive and negative selectors. In the toggle SELEX, we conducted eight cycles of selection using islets and acinar tissue from mice, followed by two cycles of selection using human tissues. The polyclonal libraries from the two selection strategies showed a convergent evolution of ligands and increased specificity for human islets.
