Abstract
Objective
Multiple Myeloma (MM) is a heterogeneous cytogenetic disorder in which
clonal plasma cells proliferate in the bone marrow (BM) and cause bone destruction. The
BM microenvironment plays a crucial role in pathogenesis of this disease, and mesenchymal
stem cells (MSCs) are one of the key players. Herein, we propose to investigate
the expressions of hsa-MIR-204, runt-related transcription factor 2 (RUNX2), peroxisome
proliferator-activated receptor gamma (PPARγ), and B-cell lymphoma 2 (BCL2) as factors
involved in osteogenesis, adipogenesis, and MSC survival in BM-MSCs from MM patients
and normal individuals.
Materials and Methods
In this experimental study, we isolated MSCs from BM aspirates
of MM patients and healthy donors. Total RNA were extracted before and after co-culture
with L363 myeloma cells. Gene expressions of RUNX2, PPARγ, BCL2, and hsa-MIR-204
were assessed by quantitive real time polymerase chain reaction (qRT-PCR).
Results
Higher levels of RUNX2, PPARγ, and hsa-MIR-204 expressions existed in MM-
MSCs compared to normally derived (ND)-MSCs. BCL2 expression decreased in MM-
MSCs. We observed different results in the co-culture model.
Conclusion
In general, the MM-MSCs gene expression profile differed compared to ND-
MSCs. Upregulation of RUNX2, PPARγ, and hsa-MIR-204 in MM-MSCs compared to ND-
MSCs would result in formation of bone defects. Downregulation of BCL2 would lead to
MM-MSC cell death.
