Figure Lengend Snippet: ( A ) The validation of RGMA mRNA gene expression levels using qRT-PCR in HD CD4 + ( n = 6) and HAM CD4 + T cells ( n = 6). ( B ) Expression of RGMa protein in CD3 + CD4 + CCR4 + T cells from HAM-PBMCs. Representative dot plots of CCR4 and normal goat IgG (upper) or RGMa expression (bottom) in CD3 + CD4 + gated cells from HD-PBMCs (left) or HAM-PBMCs (right) cultured for 2 days. ( C ) Graph shows the percentage of RGMa protein–expressing cells in CCR4 – cells or CCR4 + cells in CD3 + CD4 + gated cells from HAM-PBMCs ( n = 8) cultured for 2 days, compared with the isotype control, normal goat IgG. ( D ) Graph shows the percentage of RGMa protein–expressing cells among CD3 + CD4 + CCR4 + gated cells from HD-PBMCs ( n = 5) or HAM-PBMCs ( n = 8) cultured for 2 days. Data are shown as mean ± SD. * P < 0.05; ** P < 0.01 by unpaired t test ( A and D ) or 1-way ANOVA with Dunnett’s multiple-comparison test.

Article Snippet: In the experiment analyzing Tax , HBZ , and RGMA gene expression levels in cultured HAM-PBMCs, mRNA was purified using the Magnetic mRNA isolation kit (New England BioLabs).

( A ) Tax (left), HBZ (middle), and RGMA (right) gene expression levels in cultured HAM-PBMCs ( n = 7) in a time-dependent manner. RPL19 was used as an internal control. ( B ) Tax-dependent RGMA mRNA gene induction in Jurkat cells, which were infected with lentivirus carrying the Tax gene. Top: Tax expression in the Jurkat cells was confirmed by Western blotting. β-Actin was measured as an internal control. Bottom: The induction levels of the RGMA gene were evaluated by qRT-PCR in a time-dependent manner ( n = 3). ( C ) Tax -dependent RGMA mRNA gene induction in JPX9 cells treated with 20 μM CdCl 2 in a time-dependent manner. Tax mRNA (upper) and RGMA mRNA (bottom) were measured by qRT-PCR ( n = 3). GAPDH was measured as an internal control. ( D ) Tax-dependent RGMa protein induction in JPX9 cells treated with 20 μM CdCl 2 for 3 days. Dot plots of Tax and normal goat IgG (upper) or RGMa expression (bottom) in JPX9 cells. JPX9(-), untreated JPX9 cells; 20 μM CdCl 2 JPX9, CdCl 2 -supplemented JPX9 cells. Data are shown as mean ± SD. * P < 0.05; ** P < 0.01; *** P < 0.001 by 1-way ANOVA with Dunnett’s multiple-comparison test ( A ), 2-sided Student’s t test ( B ), or an unpaired t test ( C ). Experiments were performed in triplicate ( B and C ).
