In addition, the analysis of single-cell data from Lee et al., [35] showed that 25 circRNA host genes out of the 32 identified in our study were expressed in normal and, with lower levels, in tumor epithelial cells, while only seven (LINC00632, SLC8A1, LPAR1, WDR78, RELL1, APLF, RHOBTB1) had a prevalent expression in the stromal cells (Table S1D). This evidence concerns the gene LINC00632 and neoplasm.
