Positive correlations were found between the expression of 5-LOX in tumour cells with TG2 (r = 0.34, p = 0.010), CD3 (r = 0.32, p = 0.013), CD4 (r = 0.47, p < 0.001), and CD8 (r = 0.27, p = 0.039), respectively, whereas 5-LOX in tumour cells negatively correlated to GzmB (r = -0.35, p = 0.006). The gene discussed is CD4; the disease is neoplasm.
