Regretfully, we detected neither significant association between STIM1 gene expression (and STIM1 score) to the PD-L1 expression status (positive vs. negative; GSE65041; n = 11) nor responsiveness to anti-PD1 (responsive [complete or partial response] vs. non-responsive [progressive disease]; GSE78220; n = 27) therapy in melanoma patients (all logistic regression test p > 0.05; Figure 5D). The gene discussed is STIM1; the disease is melanoma.
