RET isoform-specific interaction with scaffold protein Ezrin promotes cell migration and chemotaxis in lung adenocarcinoma

Lung adenocarcinoma (LUAD) is a common histological type of non-small cell lung cancer (NSCLC), accounting for nearly 40% of all lung cancers [1]. Current research has identified several LUAD-specific oncoproteins with differential expression of wildtype or mutant forms, which includes the REarranged during Transfection (RET) receptor tyrosine kinase (RTK). The expression and activation of RET has been implicated in multiple cancers, including lung [2,3]. RET is expressed at low levels in normal lung tissues, however RET gene rearrangements give rise to chimeric proteins with constitutive kinase activity that drive tumourigenesis in early stage LUADs lacking other oncogenic variants [4].

In conclusion, the present study revealed that the upregulation of RBM47 accelerated the malignant progression of NSCLC, indicating that RBM47 may be a potential biomarker for NSCLC progression and a therapeutic target for NSCLC. PMID: 32218862 [PubMed - as supplied by publisher]

A series of 116 patients with EGFR-positive lung adenocarcinomas were treated with first/second generation EGFR TKIs. At clinical progression, 64 (55%) EGFR T790M plasma positive patients were subj...

Abstract Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality all over the world, particularly in China. Metastasis is the main factor resulting in the poor prognosis of patients with NSCLC. CXCR4 and EGFR have been widely studied due to their critical role in tumor metastasis, but it remains more elusive then the relationship between CXCR4 and EGFR. Studies have demonstrated that many tumors have been found the existence of the "cross-talk" between EGFR and CXCR4 signaling pathways. In this context, we explored the relationship between EGFR and CXCR4 signaling pathways in ...

Conclusions: Despite low accrual, majority of subjects treated with metformin had metabolic responses by PERCIST criteria on PET imaging. Contrary to the effect of metformin on most physiologic tissues, most tumors had increased metabolic activity in response to metformin.

AbstractPurposePrimary tumor (PT) and metastatic lymph node (MLN) status have a great influence on diagnosis and treatment of lung cancer. Our main purpose was to investigate the imaging characteristics of PT or MLN by applying the18F-FDG PET dynamic modeling approach for non-small cell lung cancer (NSCLC).MethodsDynamic18F-FDG PET scans were performed for 76 lung cancer patients, and 62 NSCLC cases were finally included in this study: 37 with newly diagnosed early and locally advanced lung cancer without distant metastases (group M0) and 25 metastatic lung cancer (group M1). Patlak graphic analysis (Ki calculation) based ...

Somatic alterations in the epidermal growth factor receptor gene (EGFR) result in aberrant activation of kinase signaling and occur in ∼15% of non-small cell lung cancers (NSCLC). Patients diagnosed with EGFR-mutant NSCLC have good initial clinical response to EGFR tyrosine kinase inhibitors (EGFR TKIs), yet tumor recurrence is common and quick to develop. Mechanisms of acquired resistance to EGFR TKIs have been studied extensively over the past decade. Great progress has been made in understanding two major routes of therapeutic failure: additional genomic alterations in the EGFR gene and activation of alternative kin...

AbstractAnaplastic lymphoma kinase (ALK) rearrangements have been reported in 5% to 6% of non ‐small cell lung cancer (NSCLC) patients. However, the concurrent existence of twoALK fusions within the same patient have rarely previously been reported. Moreover, considering the diversities ofALK mutations, it is necessary to evaluate the response of both double and new types ofALK fusions to ALK ‐tyrosine kinase inhibitors (ALK‐TKIs). Here, we report a case of a 64‐year‐old Chinese woman who was diagnosed with lung adenocarcinoma (ADC) who concurrently harbored two types ofALK‐rearrangements, including an unreport...

In this study, we investigated the utility of miR-3692-3p, miR-3195, and miR-1249-3p as biomarkers in non-small cell lung cancer (NSCLC). For this prospective study, 115 subjects, including 75 NSCLC patients and 40 controls, were recruited. The expression of miR-3692-3p, miR-3195, and miR-1249-3p was checked using qRT-PCR. The miRNA expression was correlated with survival outcome and therapeutic response. There were no significant differences in the mean age of NSCLC patients and controls (56.2 and 55.3  years, respectively;p = 0.3242). Majority of NSCLC patients (67%) were smokers. We observed a signifi...

Abstract MYB Proto-Oncogene Like 2 (MYBL2) is a highly conserved member of the Myb family of transcription factors and plays a critical role in regulating cell proliferation and survival. Here we show that overexpression of MYBL2 is frequently observed in lung adenocarcinoma (LUAD) and significantly correlates with advanced stage and poor patient survival. Knockdown of MYBL2 induced apoptosis in lung cancer cells and resulted in significant inhibition of cell proliferation, migration, and invasion. Notably, we identified Non-SMC Condensin I Complex Subunit H (NCAPH) gene as a direct target of MYBL2. NCAPH expressi...
