We did not find significant differences in the abundance of HuR mRNA or protein when comparing dermal neurofibromas and plexiform neurofibromas from our frozen cancer panel (Supplemental Figure 1A; supplemental material available online with this article; https://doi.org/10.1172/JCI130379DS1; see complete unedited blots in the supplemental material), nor were there differences in HuR mRNA levels in publicly available data sets (Supplemental Figure 1, B and C). Here, ELAVL1 is linked to dermal neurofibroma.
