commd7 Gene Expression in ALL

Acute lymphoblastic leukemia (ALL) is a neoplastic disorder of lymphoid progenitor cells characterized by diverse cytogenetic and molecular abnormalities with peaks of prevalence for 2-5-year-old patients and those older than 50. Treatment strategies using risk-adapted chemotherapy cure more than 80% of childhood cases, but around 20 to 30% relapse developing serious complications including death.( 1) In the past decade, the available treatments for patients with acute lymphoblastic leukemia (ALL) have rapidly expanded, in parallel with an increased understanding of the genomic features that impact the disease biology and clinical outcomes.(2) The copper metabolism MURR1 domain (COMMD) protein family involved in tumor development and progression in several types of human cancer, but little is known about the function of COMMD proteins in hematological malignancy. (3) COMMD7, a member of the COMMD, which is located on chromosome 20q11.21, has been reported associated with tumor progression in human solid cancers \[4\]. COMMD7 is overexpressed in pancreatic ductal adenocarcinoma (PDAC) cells, associated with poor prognosis. \[5\]. Another study revealed that COMMD7-overexpressed hepatocellular carcinoma (HCC) cells promoted the proliferation of naïve HCC cells (6) A recent study was found that high expression of COMMD7 is a potential biomarker for adverse outcomes and poor prognosis in AML. (7) . However, to date, the expression of COMMD7 in acute lymphoblastic leukemia and its prognostic value remain unclear.
