We first examined FABP gene expression in MM cell lines and found that FABP5 was the most highly-expressed FABP isoform in GFP+/Luc+MM.1S and RPMI-8226 cells (Supplementary file 1, Fairfield et al., 2021) and that some other FABPs were also expressed to a lesser extent (eg. FABP3, FABP4, and FABP6). This evidence concerns the gene FABP3 and Miyoshi myopathy.
