To determine if the decrease of surface ERp57 and CRT by integrins is not limited to our observation in Jurkat T-lymphoblasts, we repeated key assays using the T-ALL cell lines DND-41, THP-6, REX, and SUP-T1, as well as 2 primary human T-ALLs that had been expanded as xenografts (PDX). The gene discussed is CALR; the disease is acute lymphoblastic leukemia.
