TP53 and neoplasm: In addition, we demonstrated that KRasLSLG12Vge/+o;P53(+/+) mice developing LUAD tumours but lacking IL‐11RA expression (IL‐11A KO) exhibited significantly smaller tumours compared with those expressing IL‐11RA (IL‐11RA WT), highlighting the role of IL‐11 signalling pathway in tumour growth (Figure 2J).
