In order to validate the microarray data, TCLlnc1 expression was detected by qRT-PCR in tumor samples of 70 PTCL patients, including 9 cases of ALK+ALCL, 6 cases of ALK−ALCL, 23 cases of AITL, and 32 cases of PTCL-NOS, as well as 16 cases of RH. Here, FTH1P24 is linked to angioimmunoblastic T-cell lymphoma.
