Figure Lengend Snippet: Experimental validation of CCNA2, CD44 and STAT1 expression in OSCC tissues and cell lines. (A) Representative IHC staining of CCNA2, CD44 and STAT1 in control and OSCC tissues. (B–D) Quantification of IHC staining index for CCNA2, CD44 and STAT1 in human oral tissues. (E–G) qPCR analysis of CCNA2, CD44 and STAT1 mRNA levels in human oral tissues. (H–J) qPCR analysis of CCNA2, CD44 and STAT1 mRNA levels in normal versus OSCC cell lines. (K,L) qPCR analysis of CRNN mRNA expression in human oral tissues and cell lines. Data are presented as mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001.
Article Snippet: Primary antibodies against Cyclin A2 (CCNA2) (Abcam, ab181973), Cluster of Differentiation 44 (CD44) (Cell Signaling Technology, #3570), and Signal Transducer and Activator of Transcription 1 (STAT1) (Proteintech, 10144-2-AP) were applied, followed by HRP-conjugated secondary antibodies and DAB detection with hematoxylin counterstaining.
