CCNK and non-small cell lung carcinoma: In turn, Żuryń et al., in their studies on a non-small-cell lung cancer cell line, demonstrated that the CCNK protein is a newly identified regulator of the Wnt/β-catenin signaling pathway, responsible for the translocation of β-catenin from the nucleus to the cytoplasm, thereby influencing the progression of lung cancer [15,24].
