EGFR and small cell lung carcinoma: This process occurs independently of the traditional Hippo pathway or MST1/2 kinases.[92] Another study highlighted a positive signaling pathway loop involving EGFR, various EGF-like ligands, and the active YAP, which collectively contribute to the initiation and progression of SCC.[93] These studies illustrated the importance of EGFR-MOB1-YAP/TAZ signaling axis in SCLC progression.
