Surprisingly, FORCP was almost undetectable in the commonly used CRC cell lines HCT116, RKO and SW48 and was expressed in only 3 out of 60 cell lines in the NCI-60 panel in previously published (Reinhold et al., 2019) RNA-seq data (Figure 1—figure supplement 1D and E, Supplementary file 1 and 2). The gene discussed is TMEM238L; the disease is colorectal carcinoma.
