Figure Lengend Snippet: SpiB expression in the FAE is unaffected in the absence of c-Rel. (A) IHC analysis of SpiB expression (green) in the FAE of c-Rel −/− and wild-type (WT) control mice. Boxed areas in upper panels are shown at higher magnification in the lower panels. Broken lines indicate the FAE boundaries. Arrows, Spi-B + cell nuclei in the FAE. (B) Morphometric analysis showed that the number of SpiB + cells in the FAE of c-Rel −/− and WT were similar. (C) RT-qPCR analysis suggested there was no significant difference in the expression of Spib mRNA levels in Peyer’s patches from c-Rel −/− or WT mice. Gene expression data are normalised so that the mean level in samples from WT mice was 1.0.

Figure Lengend Snippet: a Following optic nerve crush (ON-CR) at 6 weeks of age, Nf1 flox/flox ; hGFAP-Cre mice at 12 weeks of age have increased numbers of CD3 + cells in their optic nerves relative to those receiving a sham operation ( n = 6); however, there was no change in b Ccl4 mRNA expression by qPCR ( n = 3). c Immediately after ON-CR, Nf1 flox/flox ; hGFAP-Cre mice received intraperitoneal injections of anti-CD3 (αCD3) antibodies every other day for 6 weeks. Control mice were injected with anti-IgG antibodies. Optic nerves were analyzed at 12 weeks of age. αCD3 antibody treatment (150 µg) reduced d CD3 + cell content ( n = 5) and e proliferation (%Ki67 + cells; n = 5). f αCD3 antibody treatment following ON-CR does not change Ccl5 RNA expression by qPCR compared to IgG-treated controls (150 µg; n = 3). Increased Ccl5 RNA expression in the optic nerves (qPCR) was observed 7 days after ON-CR in g Nf1 flox/flox ; hGFAP-Cre ( n = 3), h athymic ( Foxn1 nu/nu ; n = 4), and i Rag1 −/− mice ( n = 4) compared to sham controls.

Article Title: SAMSN1 Is a Tumor Suppressor Gene in Multiple Myeloma 1 2

doi: 10.1016/j.neo.2014.07.002

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.
