CDKL2 Is Associated with HER2 Status and Overall Survival in Gastric Cancer: Comparative Analysis of CDKL2 Protein Expression and Gene Copy Number

Figure 1

H-score of CDKL2 detected by IHC. (a) Typical images of different staining intensities of CDKL2 by IHC. (b) The patient number in different levels of CDKL2 H-score. (c) The proportion of patients with high CDKL2 protein expression (IHC-high) in the HER2+ group was significantly higher than that in the HER2- group (). Upper panel, ×40, scale bar 200 μm; lower panel, ×200, scale bar 50 μm. IHC: immunohistochemistry.
