Gene set: MGUS_MM_DAVIES (C2:PERT:0093)
Standard nameMGUS_MM_DAVIES
Systematic nameC2:PERT:0093
Brief descriptionGenes differentially expressed in monoclonal gammopathy of uncertain significance (MGUS, a precursor state for multiple myeloma) versus multiple myeloma (MM) plasma cells. Fold Change uses MGUS as the baseline.
CategoryC2: Curated
Sub-categoryPERT: Experimental pertuberation
Full description or Abstract
To define specific pathways important in the multistep transformation
process of normal plasma cells (PCs) to monoclonal gammopathy
of uncertain significance (MGUS) and multiple myeloma (MM), we
have applied microarray analysis to PCs from 5 healthy donors
(N), 7 patients with MGUS, and 24 patients with newly diagnosed
MM. Unsupervised hierarchical clustering using 125 genes with
a large variation across all samples defined 2 groups: N and MGUS/MM.
Supervised analysis identified 263 genes differentially expressed
between N and MGUS and 380 genes differentially expressed between
N and MM, 197 of which were also differentially regulated between
N and MGUS. Only 74 genes were differentially expressed between
MGUS and MM samples, indicating that the differences between MGUS
and MM are smaller than those between N and MM or N and MGUS.
Differentially expressed genes included oncogenes/tumor-suppressor
genes (LAF4, RB1, and disabled homolog 2), cell-signaling genes
(RAS family members, B-cell signaling and NF-kappaB genes), DNA-binding
and transcription-factor genes (XBP1, zinc finger proteins, forkhead
box, and ring finger proteins), and developmental genes (WNT and
SHH pathways). Understanding the molecular pathogenesis of MM
by gene expression profiling has demonstrated sequential genetic
changes from N to malignant PCs and highlighted important pathways
involved in the transformation of MGUS to MM.
