Figure Lengend Snippet: circRNAs expression profiles detected by microarray in the AAA group and control group. a The box plot shows the nearly identical distributions of normalized intensity values from the aortic samples of the AAA and control group. b The scatter plot is built to assess the expression variation of circRNAs between the two groups. The X and Y axes indicate the normalized intensity values of each circRNAs from the AAA and control group. The dots above the upper green line and below the lower green line represent the dysregulated circRNAs with a fold change (FC) > 2.0 between the two groups. c The volcano plot presents differentially expressed circRNAs in AAA. The vertical lines correspond to 2-fold upregulation and downregulation, the horizontal line indicates P value of 0.05. The red dots represent the differentially expressed circRNAs (FC > 2.0 and P value < 0.05). d Hierarchical clustering analysis reveals a distinguishable expression profile of circRNAs between the AAA and control group. Each column indicates an aortic sample, each row represents a circRNA. The red and green color indicate high and low expression level, respectively. e Chromosomal distribution of the differentially expressed circRNAs between the two groups

Article Title: Presence of S100A9-positive inflammatory cells in cancer tissues correlates with an early stage cancer and a better prognosis in patients with gastric cancer

doi: 10.1186/1471-2407-12-316

Figure Lengend Snippet: Expression of S100A9 in gastric cancer and adjacent non-cancerous tissues. ( A ) Different expression value of S100A9 in 72 gastric cancer tissues and paired no-cancerous tissues by analyzing data from illumina Sentrix BeadChip cDNA microarray. (B-E) Immunohistochemical staining of S100A9 in gastric cancer tissues ( B ) metastatic lymph nodes ( C ), chronic gastritis ( D ), and adjacent non-cancerous gastric mucosa ( E ). S100A9 localization was revealed as brown or red granulated loci in the cytoplasm of infiltrating inflammatory cells, especially in mononuclear phagocytes and neutrophil granulocytes. (magnification 200×).

Article Snippet: Expression of S100A9, S100A8 and S100A8/A9 were also detected in Cybrdi tissue microarray slides (IC00-01-001, Cybrdi, Xi'an, China) containing chronic gastritis with metaplasia (57 cases) and gastric carcinoma tissues (23 cases).

doi: 10.1186/1471-2407-12-316

Figure Lengend Snippet: Immunofluorescence images of S100A9, S100A8 and S100A8/A9 proteins in tissue microarray slides containing gastric cancer tissues (A-J) and chronic gastritis tissues (K-T), and chronic appendicitis tissues with exacerbation (U-Y). S100A9 and S100A8 were detected by monoclonal antibody, prelabeled with the Zenon Alexa Fluor Mouse IgG Labeling Kit (with green and red fluorescence respectively). The nucleus was stained by DAPI. S100A8/A9 heterodimers were detectable using the dimer-specific antibody 27E10 from BMA Biomedicals prelabeled with green fluorescence. The co-localization of S100A9 and S100A8 or S100A8/A9 was showed in merged pictures ( D , I , N , S , X ) and larger merged pictures ( E , J , O , T , Y ). White arrow in 3 T shows co-localization of S100A9 and S100A8/A9 in chronic gastritis. Bar length, 50 μm.
