Expression analysis showed that Lrmp (lymphoid-restricted membrane protein), Hcls1 (hematopoietic cell specific Lyn substrate 1) and Prkrir (protein-kinase, interferon-inducible double stranded RNA dependent inhibitor, repressor of (P58 repressor)) were up regulated and Ptp4a3 (protein tyrosine phosphatase type IVA), a phosphatase also known as Prl3 (phosphatase of regenerating liver 3) was down regulated in the respective murine tumor. The gene discussed is PTP4A3; the disease is neoplasm.
