Fig. 6: Immunohistochemical analysis of CSK, ULK3, and ADH5 expression in Luminal A breast cancer tissues.

a Representative images showing CSK, ULK3, and ADH5 expression in Luminal A breast cancer tissues and adjacent normal tissues. Positive staining is indicated by brown coloration. b Quantitative analysis of protein expression in tumor and adjacent tissues in Luminal A breast cancer. Quantification of CSK, ULK3, and ADH5 expression levels in cancer tissues compared to normal tissues. AOD average optical density, T tumor, N normal. *P < 0.05, **P < 0.01, ***P < 0.001. Data are presented as mean ± standard deviation. (N = 25 biologically independent samples).
