KPNB1 and classic Hodgkin lymphoma: We compared our data and those previously reported and found nine proteins common to NALM6wt/E571K and MedB1 (Figure S7) Although these proteins are potentially interesting and relevant for PMBL and cHL pathologies (Supplementary results, Section 2.2), we focused on karyopherin β1 (KPNB1), also known as importin 1 (or IPO1).
