Immunohistochemical analysis of SPAG9 expression in cervical cancer tissues (a) Negative control (stained with secondary antibody only) (b) positive control probed with anti-SPAG9 antibody (c) weak positive staining (intensity 1+) (d) moderate (intensity 2+) (e) strong positive staining (intensity 3+) probed with anti-SPAG9 antibody. f Violin plot shows the expression of SPAG9 in different stages of TCGA-cervical cancer (CESC) patients datasets (n = 281), (g) Kaplan–Meier plot represents the overall survival of patients with low (blue) and high (red) expression of SPAG9 (vertical line represents event occurred) n = 146 in each category)
