Cell Signaling Technology Inc rabbit anti rnf20 antibody
A. Images of tumorspheres from 3 lung adenocarcinoma tissues (Samples 1, 2, and 3). B. Western Blot analysis of CD133 (as a surface biomarker of CICs), CD44 (as another surface biomarker of CICs), USP22, <t>RNF20,</t> and H2Bub1, shows enriched USP22 protein in tumorspheres compared to original cancer tissues. C. Flow cytometry analysis of CD133 expression demonstrates a strong CD133 expression in about 30% of tumorsphere cells. D. Western Blot analysis demonstrates USP22 is markedly elevated, while H2Bub1 were significantly deceased in CD133+ cancer cells compared to CD133− cells sorted from tumorspheres. E. Flow cytometry analysis of CD44 expression demonstrates a strong CD44 expression in about 12% to 44% of tumorsphere cells. F. Western Blot analysis demonstrates USP22 and CD133 are markedly elevated, while H2Bub1 and RNF20 were markedly or moderately deceased in CD44+ cancer cells compared to CD44− cells sorted from tumorspheres. G. Mouse xenografts generated by both CD133− and CD133+ cancer cells isolated from tumorspheres, indicating CD133+ cells may represent CICs with stem cell characteristics in tumorspheres.

A. Images of tumorspheres from 3 lung adenocarcinoma tissues (Samples 1, 2, and 3). B. Western Blot analysis of CD133 (as a surface biomarker of CICs), CD44 (as another surface biomarker of CICs), USP22, RNF20, and H2Bub1, shows enriched USP22 protein in tumorspheres compared to original cancer tissues. C. Flow cytometry analysis of CD133 expression demonstrates a strong CD133 expression in about 30% of tumorsphere cells. D. Western Blot analysis demonstrates USP22 is markedly elevated, while H2Bub1 were significantly deceased in CD133+ cancer cells compared to CD133− cells sorted from tumorspheres. E. Flow cytometry analysis of CD44 expression demonstrates a strong CD44 expression in about 12% to 44% of tumorsphere cells. F. Western Blot analysis demonstrates USP22 and CD133 are markedly elevated, while H2Bub1 and RNF20 were markedly or moderately deceased in CD44+ cancer cells compared to CD44− cells sorted from tumorspheres. G. Mouse xenografts generated by both CD133− and CD133+ cancer cells isolated from tumorspheres, indicating CD133+ cells may represent CICs with stem cell characteristics in tumorspheres.

Figure Lengend Snippet: Figure 6. Endothelial RNF20 influences NPCs proliferation and differentiation by secreting CILP2 (A and B) Gene Ontology (GO) analysis for downregulated or upregulated genes in the RNF20-depleted ECs at E13.5 cerebral cortex. (C) Heatmap shows global genes were sorted by fold change. (D) Volcano plots illustrated the downregulated (blue) and upregulated (yellow) genes in the ECs of Rnf20fl/flmice and Rnf20cKO-Tie2 mice. The Cilp2 gene indicated by the red dots highlighted the significant reduction in downregulated genes. (E) Heatmaps were further analyzed. The Cilp2 gene was one of the significantly differentially expressed genes. (F) Six significantly expressed genes were analyzed by qPCR in ECs of Rnf20fl/flmice and Rnf20cKO-Tie2 mice, of which Cilp2 has the highest expression. n = 3 independent experiments.
