In previous studies, higher expressions of gangliosides GD2/GM2 have been found in multiple types of tumors including neuroblastoma, breast cancer, lung cancer [5], and cervical cancer [19], which were consistent with our results as the high expression of GD2/GM2 can result from the high expression of B4GALNT1. The gene discussed is B4GALNT1; the disease is breast carcinoma.
