YBX1-dependent LNA-tRF-mediated modulation of transcript stability

ABSTRACT: In order to identify YBX1-dependent targets that are modulated upon changing the levels of endogenous tRFs, we used transient transfection of antisense locked-nucleic acids (LNAs) against tRFAsp, tRFGly, tRFGlu, and tRFTyr followed by alpha-amanitine treatment, RNA extraction at time points 0 and 8hr post-treatment, and transcriptomic profiling.

YBX1-dependent LNA-tRF-mediated modulation of transcript stability

Project description:In order to identify YBX1-dependent targets that are modulated upon changing the levels of endogenous tRFs, we used transient transfection of antisense locked-nucleic acids (LNAs) against tRFAsp, tRFGly, tRFGlu, and tRFTyr followed by alpha-amanitine treatment, RNA extraction at time points 0 and 8hr post-treatment, and transcriptomic profiling. Synthetic antisense locked-nucleic acids (LNAs) targeting the YBX1 binding site on tRFAsp, tRFGly, tRFGlu, and tRFTyr were transfected into control and YBX1-knockdown cells to identify YBX1-dependent targets whose stabilities are modulated due to tRF loss-of-function. We used alpha-amanitine mediated inhibition of RNA-polymerase to measure transcript stability across the entire transcriptome.

YBX1-dependent LNA-tRF-mediated modulation of gene expression under hypoxia

Project description:In order to test whether inhibition of tRFs induced under hypoxia would counteract the YBX1-dependent reduction of target transcripts, we used transient transfection of antisense locked-nucleic acids (pooled LNAs) against tRFAsp, tRFGly, tRFGlu, and tRFTyr under hypoxia followed by microarray profiling. Synthetic antisense locked-nucleic acids (LNAs) targeting the YBX1 binding site on tRFAsp, tRFGly, tRFGlu, and tRFTyr were transfected (as a pool) in control and YBX1-knockdown cells under hypoxia to assess the consequences of inhibiting tRFs induced in hypoxic MDA-parental cells.

Inter-organellar communication by a mitochondrial tRNA regulates nuclear metabolic transcription (RNA-Seq)

Project description:To assess transcriptomic changes that occur upon mito-tRNA Asparagine inhibition, MDA-MB-231 cells were transfected with either a non-targeting control locked nucleic acid (LNA), two independent LNAs targeting mito-tRNA Asparagine, or an LNA against mito-tRNA Lysine.

YBX1 HITS-CLIP

Project description:In order to identify YBX1 binding sites on endogenous RNA, we performed HITS-CLIP on endogenous YBX1 We used a previously published method to perform HITS-CLIP on endogenous YBX1 (Licatalosi D, et al. 2008, Nature 456:464-U22)

Chip-chip from HCT116 cells with YBX1

Project description:YBX1 is a multifunctional protein involved in the control of transcription and translation. We identified YBX1 as an target of MEK/ERK signaling in colorectal cancer cell lines. We performed a ChIP-chip analysis of HCT116 cells to identify new potential target genes of YBX1. Comparison of input DNA fragments with fragments coprecipitated with YBX1 in HCT116 cells.

YBX1-dependent hypoxia-induced modulation of gene expression

Project description:In order to identify YBX1-dependent targets that are modulated under hypoxic conditions, we used control and YBX1 knockdown cells grown under normoxia and hypoxia to profile gene expression levels. Control and YBX1-knockdown cells were grown and profiled under hypoxia and normoxia to identify YBX1-dependent hypoxia-induced target transcripts.
