# Overview

mRNA half-life is a measure of the degradation rate of mRNA molecules. This experiment reports the time that the expression level of a transcript takes to decrease by half. The original data source aggregates 39 human and 27 mouse transcriptome wide datasets -- this dataset contains the mouse datasets. Several data preprocessing steps are taken, reported in the original paper. Half-life measures per gene averaged across collected datasets, and PCA is performed on the gene x half-life matrix. To reduce experimental noise, this dataset reports the value of the first principle component.

This dataset is redistributed as part of mRNABench: https://github.com/morrislab/mRNABench

# Data Format

Description of data columns:
- `target`: First PCA component of half-life measurements across aggregated datasets.
- `cds`: Binary track which reports position of first nucleotide in each codon in CDS.
- `splice`: Binary track which reports position of the 3' end of each exon, indicating splice sites.

This dataset is a Hugging Face redistribution of the mRNA half-life dataset originally collected in the Saluki paper (Agarwal and Kelley 2022), which itself is a collection of experimental datasets.
