In addition, gene expression analysis allowed the authors to identify highly proliferating lymphocytes and those clusters had 17-gene expression signature common to all tumours: ACTG1, ANP32B, ATP5C1, DUT, HMGN1, HN1, NPM1, NUSAP1, PCNA, PPA1, PPIA, PSMB2, RAN, RANBP1, SET, SMC4, and STMN1. The gene discussed is NUSAP1; the disease is neoplasm.
