Objective. To compare gene expression profiles
between ankylosing spondylitis (AS) and undifferentiated
spondylarthritis (uSpA) patients with inflammatory
low back pain.
Methods. Peripheral blood mononuclear cells
(PBMCs) from patients with AS, patients with uSpA,
and healthy subjects were screened using genome-wide
microarrays, followed by validation by real-time polymerase
chain reaction (PCR).
Results. Microarray profiling and real-time PCR
