Mapping the targeting transcripts and binding sites of ALKBH5 by individual-nucleotide resolution UV crosslinking and immunoprecipitation-based sequencing (iCLIP-seq)

Project description:To investigate whether the ALKBH5-mediated metabolic changes via demethylation of its target mRNA(s) is important in regulating viral response, we mapped the targeting transcripts and binding sites of ALKBH5 in the virus infected cells and uninfected cells by using iCLIP-seq. Biological replicates of iCLIP-seq confirmed that OGDH is the direct targeting transcript of ALKBH5 and the binding capacity of ALKBH5 to OGDH mRNA was decreased upon viral infection. By combining the ALKBH5-iCLIP-seq results with m6A-seq data, we identified that there are overlapped ALKBH5-iCLIP peaks and m6A-seq peaks on OGDH mRNA. Furthermore, other mRNAs, such as GOT2 mRNA, were also the ALKBH5’s targeting transcripts and m6A demethylation substrates. GOT2 is an important metabolic enzyme well known to be involved in host response to viral infection. These data demonstrated that ALKBH5-mediated metabolic rewiring via demethylation of target OGDH mRNA and other transcripts is important in regulating cellular viral replication.

U1A iCLIP-seq (individual-nucleotide resolution UV crosslinking and immunoprecipitation coupled with RNA sequencing) analysis in HeLa cells

Project description:To better understand the mechanism of U1A functions in human cells, we performed U1A iCLIP-seq analysis in HeLa cells. iCLIP-seq is a previously well-established protocol that is believed to detect protein-RNA interaction at individual-nucleotide resolution. Indeed, successful completion of U1A iCLIP-seq has helped us to illuminate more detailed mechanism through which U1 snRNP prevents mRNA PCPA (premature cleavage and polyadenylation)

Individual nucleotide resolution Crosslinking Immunoprecipitation (iCLIP)-seq

Project description:Purpose: to identify the AGO1-bound miRNAs and mRNAs in human endothelial cells subject to hypoxic condition (2% oxygen) Methods: human microvascular endothelial cells was cultured under normoxia (20% oxygen) or hypoxia (2%) oxygen for 24 hours. Total RNA was extracted and RNA and small RNA libraries were prepared for Seq. Results: We found substantial changes in AGO1-bound mRNAs due to hypoxia. A portion of CLIP-seq reads also reveal direct binding to miRNA to mRNA. Conclusions: hypoxia induces profound changes in mRNAs associated with AGO1.

Identification of Meiotic-P26-bound RNAs in cutlured Drosophila SL2 cells by iCLIP (individual-nucleotide resolution UV crosslinking and immunoprecipitation)

Project description:The TRIM-NHL protein Meiotic P26 (Mei-P26) governs gene expression and controls stem cell fate in Drosophila. Mei-P26 represses the translation of the key regulator protein Nanos and induces miRNA-dependent silencing to regulate stem cell renewal, differentiation and proliferation. The structural and mechanistic details of mRNA target recognition and RNA binding by its C-terminal NHL domain remain elusive. To identify its cellular target RNAs, we performed iCLIP2 experiments in cultured Drosophila SL2 cells that were transfected with Flag-tagged Mei-P26 full-length, or its NHL domain.
