As for the stretch‐ and swelling‐activated TRPM7 channel, despite a strong connection between its overexpression, metastasis and a poor prognosis in numerous cancer types (Guilbert et al, 2009, 2013; Middelbeek et al, 2012; Chen et al, 2015; Yee et al, 2015; Gao et al, 2017; Rybarczyk et al, 2017), its expression has been shown to be steady overall in both melanocytes and melanoma cells, and did not correlate to melanoma cell lines' invasive potential (McNeill et al, 2007). The gene discussed is TRPM7; the disease is melanoma.
