MATN3 and cancer: Our work systematically explored the role of MATN3 in cancer in terms of MATN3 expression and clinical features, diagnostic value, prognosis, gene mutation, drug sensitivity, methylation and its prognosis, immune infiltration, immune checkpoints, TMB, and MSI, and the results showed that MATN3 was significantly correlated with these factors, which could provide a better tool for us to follow up and explore the potential value of MATN3 in cancer.
