Figure Lengend Snippet: Figure 2. Electroacupuncture (EA) protected neurons against spinal cord injury (SCI)-induced apoptosis. Tissues were obtained and processed as described for Fig. 1 and in Methods. A. Nissl staining of spinal cord. Upper panel shows full cross sections of spinal cord, scale bar = 500 μm. Lower panel shows partial enlargement of sections, scale bar = 50 μm; B. Representative images showing immunofluo- rescence of TUNEL+/NeuN+ in rat spinal cord, scale bar = 50 μm; C. Quantification of percentage of TUNEL and NeuN dual-positive cells in spinal cord; D. Left panel shows immune blots of B-cell lymphoma-2 associated X protein (Bax), BH3-interacting domain death agonist (Bid), and B-cell lymphoma-2 (Bcl-2). Right panel shows quantification of Bax, Bid, and Bcl-2 protein expression in lysates of spinal cord. Numeric data refers to Figs. 2C, D, results expressed as mean ± standard deviation, n = 6 in each group. *P < 0.05, **P < 0.01, ***P < 0.001, API — 4’,6-diamidino-2-phenylindole; Ns — not significant.

Article Snippet: The PVDF membrane was blocked with a membrane sealing solution (Solarbio) at RT for 1 h. Primary antibodies [B-cell lymphoma-2 (Bcl-2; 1:1,000, Proteintech), BH3-interacting domain death agonist (Bid; 1:1,500, Proteintech), B-cell lymphoma-2 associated X protein (Bax; 1:5,000, Proteintech), JAK2 (1:1,500, Affinity), STAT3 (1:2,000, Proteintech), Phospho-JAK2 (p-JAK2; 1:800, ABclonal, Wuhan, China), p-STAT3 (1:1,000, Affinity), and glyceraldehyde phosphate dehydrogenase (GAPDH; 1:10,000, Proteintech)] were incubated with the PVDF membranes overnight at 4°C and washed with Tris-buffered saline with tween-20 (TBS-T) buffer.

Figure Lengend Snippet: (A) Manhattan plot showing all splice variant SNPs across the 49 phenotypes. For each splice variant, the best p value observed among all assessed traits is plotted on a –log10 scale (y axis), according to its genomic coordinates (x axis). Gramd4 splice variant chosen for validation is highlighted in red. (B) Variation in frequency of BM pre-cDCs in C57BL/6J (gray; n = 3), 129 (pink; n = 3), NOD (blue; n = 3), NZO (cyan; n = 3), A/J (yellow; n = 3), WSB (purple; n = 3), DO (black; n = 170), and CC-RI (open; n = 47) mice. (C) A QTL driving the frequency of BM pre-cDCs found within chromosome 15 (chr15:86,581,607, LOD = 10.7) that appears to be driven by an A/J and NZO founder effect. (D) Gramd4 gene structure and schematic representation of alternative splicing (UCSC Genome Browser). SNP localization is shown in red. (E) Western blot on total splenocytes from Gramd4 w/w and Gramd4 sp/sp mice showing alternative splicing. (F) Schematic representation of mixed BM chimera experiment. (G) Representative flow cytometry plot for mixed BM experiment. (H) Frequencies of DC progenitors and subsets in mixed BM chimera mice due to differential expression of Gramd4 SNP variant in BM, spleen, and inguinal LN. Chimerism is expressed as the ratio between the number of CD45.2 and CD45.1/CD45.2 cells for each cell population. Representative of 2 independent experiments; each dot represents one mouse, n = 6 per group, Gramd4 w/w (red) and Gramd4 sp/sp (blue), and horizontal lines represent means. (I) Schematic representation of the experimental setup in (J) and (K). (J) Representative flow cytometry plot for OT-II CD4 + T cell activation (CTV dilution after immunization with OVA 328–339 peptide in alum) in popliteal LN of Gramd4 w/w and Gramd4 sp/sp recipient mice. Graph shows the absolute numbers of OT-II cells in popliteal lymph nodes and the x axis the number of divisions after immunization. (K) CD69 and CD43 expression of divided OT-II T cells in popliteal LN of Gramd4 w/w and Gramd4 sp/sp recipient mice. Each dot represents one mouse, n = 6 per group, Gramd4 w/w (orange) and Gramd4 sp/sp (green), and horizontal lines represent means (J and K). Student’s t test, * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001. iLN (inguinal LN).
