a Scheme of the vil-Cre-ERT2; p53lox/lox; Myclox/lox mouse models. b Experimental design for the tumorigenesis in these mice. c H&E of the intestinal tumours found in p53(Δ/Δ)vil; Myc(+/+)vil mice; and p53(Δ/Δ)vil; Myc(Δ/Δ)vil mice. d Percentage of mice presenting tumours in these models. e Number of tumours found in the indicated mice (n = 8, 17). f IF staining of URI in a tumour from p53(Δ/Δ)vil; Myc(+/+)vil mice. g Scheme of the vil-Cre-ERT2; p53lox/lox; URIlox mouse model. h Experimental design for tumorigenesis in these mice. i Pictures of H&E staining of intestinal tumours found in p53(Δ/Δ)vil; URI(+/+)vil and p53(Δ/Δ)vil; URI(+/Δ)vil mice. j Proportion of mice presenting intestinal tumours. k Number of intestinal tumours found in these mice (n = 8, 34). l Experimental design for ageing experiments in these mice. m Kaplan-Meier curve indicating survival probability and time (in days) of the corresponding mice. n Scheme of the vil-Cre-ERT2; p53lox/lox; villin-rtTA; ColA1-tetO-hURI mouse model. o Experimental design for the tumorigenesis in these mice. p Pictures of H&E staining of intestinal tumours found in p53(Δ/Δ)vil; hURI(+/+)vil mice and p53(Δ/Δ)vil; hURI(+/KI)vil mice. q Proportion of mice presenting intestinal tumours. r Number of intestinal tumours found in these mice (n = 24, 8). s Scheme of the hUb-CreERT2; p53lox/lox; URIlox mouse model. t Experimental design for tumorigenesis in these mice. u Kaplan-Meier curve indicating survival probability and time (in days) of p53(Δ/Δ)Ub; URI(+/+)Ub and p53(Δ/Δ)Ub; URI(+/Δ)Ub mice. v Percentage of mice presenting tumours in the indicated tissues. DIC = mouse dead in cage. Bars represent the mean, except in (v). Error bars represent the standard error of the mean (SEM). Dots represent individual mice. Two-sided t. test was used to compare the statistical differences between means of two different groups. Source data are provided as a Source Data file.
