Figure Lengend Snippet: SAMSN1 expression is reduced in CD138 + PCs of patients with MM and HMCL. (A) SAMSN1 expression (as determined by real-time PCR) is significantly reduced in the BMs of patients with MM ( n = 34) compared with patients with MGUS ( n = 9) and healthy age-matched controls ( n = 5; * P < .05, ** P < .001, one-way ANOVA with Tukey’s multiple comparison test). (B) SAMSN1 expression in CD138 + MACS isolated PCs from patients with MM negatively correlates with BM PC burden ( n = 10, r 2 = 0.6147, P = .0043). (C) In silico analysis of published microarray data. CD138 + PCs were isolated by MACS from 414 patients with MM, 44 patients with MGUS, and 22 age-matched controls. RNA was extracted and analyzed using the Affymetrix U133Plus2.0 microarray platform (GEO Accession Nos GSE4581 and GSE5900). Expression of SAMSN1 is significantly reduced in PCs of patients with MM compared to those of patients with MGUS and normal controls. P < 0.0001, one-way ANOVA with Tukey’s multiple comparison test. (D) Total RNA was extracted from six HMCLs and reverse transcribed. The levels of SAMSN1 expression were assessed by real-time PCR.

Article Snippet: PCs were isolated from flushed long bones and identified using rat anti-mouse CD138 (R&D Systems, Minneapolis, MN) followed by PE-conjugated goat anti-rat IgG.
