1. Proposed model of the tumor-suppressive effects of TPL2 in the lung.
Proposed model of the tumor-suppressive effects of TPL2 in the lung. TPL2 contributes to p53 response to DNA damage caused by genotoxic agents or oncogenic stress through JNK-dependent up-regulation of nucleophosmin. Genetic or epigenetic aberrations (e.g., loss of heterozygosity, overexpression of miR-370, or oncogenic RAS signaling) may independently induce TPL2 down-regulation, leading to diminished JNK and p53 responses, reduced cell death, and accelerated carcinogenesis.
