#Mps 1 disease Activator#

Activation of this core module results in the LATS1/2-mediated phosphorylation and consequent cytoplasmic retention of the transcriptional coactivators YAP (Yes-associated protein) and TAZ (transcriptional coactivator with PDZ binding motif).

2, 3 The Hippo pathway in mammals comprises four core components: mammalian Ste20-like kinase (MST) 1/2, large tumor suppressor kinase (LATS) 1/2, salvador 1 (SAV1), and Mps one binder kinase activator 1 (MOB1). The Hippo signaling pathway was initially identified in Drosophila and is highly conserved in mammals as a regulator of tissue homeostasis and regeneration, organ size, and tumorigenesis. Characterization of the signaling pathways associated with tumor progression would thus be expected to be of clinical value for the treatment of NSCLC. 1 Individuals with early-stage lung cancer who undergo curative surgical resection often experience recurrent disease or the development of distant metastases.

Our results thus suggest that high MOB1 expression is a risk factor for early postoperative recurrence in lung adenocarcinoma.Дespite the recent advances in targeted therapy for lung adenocarcinoma, non-small cell lung cancer (NSCLC) remains the most common cause of cancer death worldwide. MOB1 expression also promoted the invasiveness of NSCLC cells in vitro. We found that high MOB1 expression in surgical specimens of lung adenocarcinoma was associated with poor disease-free survival and with intratumoral vascular invasion. Key points Significant findings of the study Our results suggest that MOB1 might promote early recurrence of NSCLC by increasing vascular invasion by tumor cells. The invasiveness of H1299 cells in vitro was increased or attenuated by overexpression or knockdown of MOB1, respectively. Multivariate analysis also identified high MOB1 expression as a significant independent risk factor for disease-free survival ( P = 0.0319). Among the various clinicopathologic parameters examined, high MOB1 expression was significantly associated only with intratumoral vascular invasion ( P = 0.0005). ResultsД®xpression of MOB1 was classified as high in 105 of the 205 (51.2%) tumor specimens, and such high expression was significantly associated with poor disease-free survival ( P = 0.0161). Invasive activity of NSCLC cell lines in vitro was measured with a transwell assay. MOB1 expression in tumor cells of surgical specimens was evaluated by immunohistochemistry. We retrospectively analyzed 205 lung adenocarcinoma patients treated at Kyushu University Hospital between November 2007 and October 2012. Here, we evaluated the possible relationship of MOB1 expression in non-small cell lung cancer (NSCLC) to prognosis. Mps one binder kinase activator 1 (MOB1) is a core component of the Hippo signaling pathway and has been implicated as a tumor suppressor.
