GLP-1 induced transcriptomic profile in INS-1 cells


ABSTRACT: Aim: The purpose of this RNAseq study is to gain insight into the effect that Glucagon Like Peptide-1(GLP-1) or BMS-21 (11 amino acid GLP-1 mimetic) has on the transcriptomic profile of an insulin secreting pancreatic beta cell line INS-1 at 1h and 6h. Methods: The mRNA-focussed libraries (constructed using TruSeq RNA Library Prep Kit v2) of GLP-1 or BMS-21 treated INS-1 cells at 1h or 6h were generated by sequencing, in quadruplicate, using an Illumina Hiseq2000. De-multiplexing and FASTQ sequence data was generated using the Illumina CASAVA1.8.2 pipeline. The sequence reads that passed quality filters were analyzed at the transcript level using the following. Alignment using TopHat (2.0.12) + Bowtie (2.2.3.0) to the illumina rat iGenome (build 75 - Rnor_5.0 (GCA_000001895.3)), reads summarised using Subread-feature counts (1.4.6) and differential gene analysis using DESeq2 (1.6.3) within Rstudio (0.98.945). Results: GLP-1 treatment of INS-1 cells induced many transcriptomic changes in gene expression at both 1h and 6h relative to control at 1h and 6h. At 1h following GLP-1 treatment there were 674 genes differentially expressed (470 up-regulated and 204 down-regulated, p-adj <0.05). Further, at 6h following exposure to GLP-1 treatment there were 3192 genes differently expressed (1709 up-regulated and 1,483 down-regulated, p-adj <0.05). Comparison of GLP-1 and BMS-21 treatments revealed highly similar transcriptomic profiles at both the 1h and 6h timepoints. Conclusion: GLP-1 has a varied effect on the transcriptomic profile of INS-1 cells.
