We further analyze the cancers without normal tissues in the TIMER database via the GEPIA database, and the results showed that XRCC4 was significantly upregulated in lymphoid neoplasm diffuse large B-cell lymphoma (DLBC), glioblastoma (GBM), LGG and THYM (Fig. 1C). Here, XRCC4 is linked to diffuse large B-cell lymphoma.
