COL11A1 and neoplasm: It is not difficult to find that biomarkers such as Effector T-cell, Naïve T -cell, Effector Memory T-cell and Resident Memory T-cell related to tumor immunity in T cell subsets are negatively correlated with COL11A1 expression while the infiltration level of Treg and Resting Treg (Zhang et al., 2021; Malla et al., 2022) that have been previously confirmed by a large number of literatures to have tumor immunosuppressive effect and participate in tumor progression, were positively correlated with COL11A1 expression.
