Figure 4 depicts evidence that miRNAs target FGRs identified by the GSCALite program. Using ChIP-seq datasets, we also discovered transcription factors that may posttranscriptionally modulate FGRs expression (Table 3). Hsa miR- 37–3p has experimentally verified to target ironoptosis-related SLC1A5 in melanoma (doi: 10.1038/s41418-017-0053-8). This evidence concerns the gene SLC1A5 and melanoma.
