Figure Lengend Snippet: Analysis of selected senescence markers and anillin levels in HCT 116 p53KO cells induced to senescence by doxorubicin treatment for 1 day and collected 5 days after senescence induction.

Statistical significance is shown for differences between indicated cell lines. Relative protein expression means fold change (in the expression of proteins relative to the expression of GAPDH) vs appropriate control.

doi: 10.14336/AD.2025.0402

Figure Lengend Snippet: Inverse correlation between ANLN and p53 during senescence and escape from senescence in cancer cells. Downregulation of anillin is a consequence of the induction of p53 due to cellular senescence. After some time, senescent cells resume divisions, which is associated with a decrease in p53 levels and an increase in anillin. Performed with Biorender.
