LBX1 and melanoma: On the other hand, the transcriptional activity of the gene that encodes the HGF interactor MEOX2 (GAX: a homeobox protein involved in the regulation of angiogenesis and resistance to chemotherapy [76,77,78,79]), as revealed by the obtained amplification patterns of the expected 147 bp long PCR band, could be detected—albeit at low levels—in BCC and SCC biopsy samples (Figure S1G), but was completely absent from melanoma ones (Figure S1H).
