Interestingly, depleting CDK2 in lung adenocarcinoma cell lines resulted in similar mitochondrial morphological changes caused by DRP1 depletion and led to an extensive mitochondrial tubular network in CL1‐0 cells and perinuclear compaction of swollen mitochondria in A549 cells (Fig. 6E and Fig. S10B). This evidence concerns the gene CDK2 and lung adenocarcinoma.
