Differences in expression of RIPK1, RIPK3, and pMLKL were examined by comparing the immunoreactive score (IRS) in the groups of histological subtypes (squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma), grading (G1-G3), TNM- and FIGO-classification. Here, RIPK3 is linked to squamous cell carcinoma.
