Article Title: Correlation between Periostin Expression and Pro-Angiogenic Factors in Non-Small-Cell Lung Carcinoma
doi: 10.3390/cells13171406
Figure Lengend Snippet: Correlation plots comparing the expression of POSTN in cells ( A – C ) and in stroma ( D – F ) with the expression of pro-angiogenic markers, as quantified via the Chalkley method, assessed in squamous-cell carcinoma. The pro-angiogenic factors are CD31 ( A , D ), CD34 ( B , E ), and CD105 ( C , F ). The plots include p -values and R-values (calculated with Spearman’s correlation test) and the number of cases, which can be seen in the lower right corner of each plot. The images in ( G – I ) show punches from tissue microarrays demonstrating an example of the immunohistochemical (IHC) staining for each individual protein, as previously described. The images in ( J – L ) show representative magnified regions of the microarray punches.
Article Snippet: The following specific primary antibodies were used in the IHC experiments: anti-POSTN rabbit polyclonal antibody (1:200 dilution, NBP1-82472, Novus Biologicals, Littleton, CO, USA), monoclonal mouse anti-VEGF-A antibody (1:50 dilution + linker, VG1 clone, M7273, Agilent Technologies, Santa Clara, CA, USA), monoclonal mouse anti-CD31 antibody (RTU, JC70A clone, IR610, Agilent Technologies, Santa Clara, CA, USA), monoclonal mouse anti-CD34 antibody (RTU, QBEnd/10 clone, IR632, Agilent Technologies, Santa Clara, CA, USA), and rabbit polyclonal anti-CD105 antibody (1:1000 dilution, 10862-1-AP, Proteintech, Manchester, UK).
