Meanwhile, after examining 33 types of tumors from the TIMER database, results showed that B4GALNT1 expression was significantly associated with infiltrating immune cells including B cell, CD8 + T cell, CD4 + T cell, macrophage cell, neutrophil cell, and dendritic cell in BRCA, LGG, PAAD, PRAD, and THYM, but whether the correlation is positive or negative differs between tumor types and cell types. The gene discussed is CD4; the disease is neoplasm.
