In the version of this article originally published, the Gene Expression Omnibus (GEO) accession number listed in the data availability section was incorrectly given as GSE10979 instead of GSE109795. The sentence should read "RNA-seq data that support the findings of this study have been deposited in the Gene Expression Omnibus (GEO) under accession code GSE109795," and the code should link to https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE109795. The error has been corrected in the HTML and PDF versions of the paper.
