- Abstract
Background/Aims: Adhesion-regulating molecule 1 (ADRM1), a receptor located on the 26S proteasome, is upregulated in many solid cancers. However, little is known about its role in acute leukemia (AL). Methods: We determined ADRM1 expression levels in both untreated AL samples and leukemia cell lines using real-time polymerase chain reaction or Western blot analysis. Growth curves, colony formation assays, cell cycle and apoptosis analyses, cell migration and invasion assays and NF-κB p65 nuclear translocation assays via Western blotting were used to examine the biological behavior of HL60 cells and the underlying mechanism. Results: ADRM1 was upregulated in both untreated AL samples and leukemia cell lines. ADRM1 knockdown significantly suppressed HL60 cell proliferation (48.82 ± 12.58%) and colony formation and caused cell cycle arrest in the G0/G1 phase. Furthermore, we confirmed that ADRM1 knockdown suppressed p65 nuclear translocation. Conclusion: Our study revealed that ADRM1 was overexpressed in AL, especially in CD34+ leukemia stem and progenitor cells. ADRM1 may play a role in AL via the proteasome-ubiquitin pathway by potentially sustaining the activation of NF-κB signaling. © 2015 S. Karger AG, Basel
