PHB1 and non-Hodgkin lymphoma: To further evaluate the expression of PHB1 and PHB2 in hematologic malignancies, Western blot analyses were performed on total cell lysates from PBMCs purified from healthy donors (n = 5) and tumor cells obtained from individuals diagnosed with B-ALL (n = 15), B-NHL (n = 18), CML (n = 10), T-ALL (n = 5) and T-NHL (n = 8).
