Interestingly, MALAT1 was recently found to positively regulate PD‐L1 in non‐small‐cell lung cancer [150] and diffuse large B‐cell lymphoma (DLBCL) [151]; furthermore, MALAT1 expression promoted DLBCL immune escape by regulating the proliferation and apoptosis of CD8+ T cells. The gene discussed is CD8A; the disease is diffuse large B-cell lymphoma.
