Project description:The lack of knowledge about extreme conservation in genomes remains a major gap in our understanding of the evolution of gene regulation. Here, we reveal an unexpected role of extremely conserved 5’UTRs in non-canonical translational regulation that is linked to the emergence of essential developmental features in vertebrate species. Endogenous deletion of conserved elements within these 5’UTRs decreased gene expression, and extremely conserved 5’UTRs possess cis-regulatory elements that promote cell-type specific regulation of translation. We further developed in-cell mutate-and-map (icM2), a novel methodology that maps RNA structure inside cells. Using icM2, we determined that an extremely conserved 5’UTR encodes multiple alternative structures and that each single nucleotide within the conserved element maintains the balance of alternative structures important to control the dynamic range of protein expression. These results explain how extreme sequence conservation can lead to RNA-level biological functions encoded in the untranslated regions of vertebrate genomes.

Project description:In this study, we directly compared turkey muscle satellite cell gene expression between satellite cells with the gene Death-Associated Protein (DAP) knocked down by siRNA transfection and those transfected with a lipofectamine control using our 6K Turkey Skeletal Muscle Long Oligo (TSKMLO) microarray (GPL9788). The DAP gene was previously identified as differentially expressed by genetic line and during development of turkey skeletal muscle (Sporer et al., 2011). Gene expression changes were investigated in satellite cells after 72 h of proliferation and after 48 h of differentiation. We identified novel candidate genes and pathways as playing potentially crucial roles in the DAP-mediated attenuation of the normal processes of proliferation and differentiation in turkey satellite cells previously identified by Velleman et al. (submitted).

Project description:In this study, we directly compared turkey muscle satellite cell gene expression between satellite cells with the gene versican (VCAN) knocked down by siRNA transfection and those transfected with a lipofectamine control using our 6K Turkey Skeletal Muscle Long Oligo (TSKMLO) microarray (GPL9788). The VCAN gene was previously identified as differentially expressed by genetic line and during development of turkey skeletal muscle (Sporer et al., 2011). Gene expression changes were investigated in satellite cells after 72 h of proliferation and after 48 h of differentiation. We identified novel candidate genes and pathways as playing potentially crucial roles in the VCAN-mediated effects on the normal processes of proliferation and differentiation in turkey satellite cells previously identified by Velleman et al.

The MGP gene was previously identified as differentially expressed by genetic line and during development of turkey skeletal muscle (Sporer et al., 2011).

We identified novel candidate genes and pathways as playing potentially crucial roles in the MGP-mediated effects on the normal processes of proliferation and differentiation in turkey satellite cells previously identified by Velleman et al. (submitted). This experiment was designed to investigate the role of MGP expression in turkey satellite cells during two crucial processes in muscle development: proliferation and differentiation. Satellite cells were isolated from 7-week-old turkeys from the RBC2 line. Cells were transfected with either MGP siRNA or a lipofectamine control; MGP expression was knocked down by over 50% with siRNA transfection (Velleman et al., submitted). Satellite cells were then induced to proliferate for 72h or differentiate for 48h; culture plates from each stage (n=4) were frozen until RNA extraction. Microarrays directly compared the MGP -knockdown to control from each of 4 culture plates and utilized a dye swap to equal 8 arrays for each of the cell developmental stages, proliferation and differentiation, and 16 arrays for the overall experiment investigating the role of MGP expression in satellite cell development and function. Hybridizations were performed in random order.
