Introduction: Our previous study identified LIM homeobox domain 6 (LHX6) as a frequently epigenetically silenced tumor-suppressor gene in lung cancer. However, its clinical value has never been evaluated, and the in-depth anti-tumor mechanism remains unclear. Methods: Public database was used for lung cancer, lung adenocarcinoma and lung squamous carcinoma patients and tissue microarray data wa...
Lung adenocarcinoma driven by somatic EGFR mutations is more prevalent in East Asians (30-50%) than in European/Americans (10-20%). Here we investigate genetic factors underlying the risk of this disease by conducting a genome-wide association study, followed by two validation studies, in 3,173 Japanese patients with EGFR mutation-positive lung adenocarcinoma and 15,158 controls. Four loci, 5p1...
Our recent studies have demonstrated that AQP5 is involved in the metastatic potential of lung cancer. Here, our aim was to explore the effects of AQP5 expression on mucin production in lung adenocarcinoma. We tested MUC5AC and MUC5B mucin production induced by AQP5 expression in lung adenocarcinoma metastasis. Lung adenocarcinoma cells with different levels of AQP5 expression were used in this...
Background: Lung cancer is the leading cause of cancer-related deaths, accounting for 1.8 million deaths (18%). Nearly 80%-85% lung cases are non-small cell cancers (NSCLC). One most frequent genetic mutations in NSCLC Kirsten Rat Sarcoma Oncogene Homolog (KRAS) gene mutation. In recent years, autophagy has drawn substantial attention as a potential pathway that can be targeted driven by KRAS m...
BACKGROUND Sialyl Lewis X-i antigen has been used as a diagnostic tool for lung adenocarcinoma. However, serum levels of the antigen are also raised in some patients with idiopathic pulmonary fibrosis (IPF) without coexistent malignancy. Expression of the antigen in serum samples of patients with lung adenocarcinoma was evaluated and compared with that of patients with IPF by Western blotting i...
Background: Lung adenocarcinoma (LUAD) is the most common subtype of non-small cell lung cancer (NSCLC). Chemotherapy resistance main cause chemotherapy failure. Cullin7 (Cul7) highly expressed in LUAD and associated with poor prognosis. Moreover, Cul7 abnormally overexpressed docetaxel-resistant cells. Therefore, further exploration role molecular mechanism docetaxel necessary.
Several studies have reported that the overexpression of Sirtuin 1 (SIRT1) was associated with poor prognosis in various human cancers. However, little is known regarding the prognostic value of SIRT1 in lung adenocarcinoma. Therefore, the aim of this study is to evaluate the role of SIRT1 in the prognosis of lung adenocarcinoma patients. Using a tissue microarray, we detected SIRT1 expression ...
The higher frequency of lung adenocarcinoma in women smokers than in men smokers suggests a role for gender-dependent factors in the etiology of lung cancer. We evaluated estrogen receptor (ER) alpha and beta expression and activity in human lung adenocarcinoma cell lines and normal lung fibroblasts. Full-length ERalpha and ERbeta proteins were expressed in all cell lines with higher ERbeta tha...
Lung surfactant protein-A (SP-A) is a major phospholipid-associated glycoprotein in surfactant, and is a useful immunohistochemical marker for lung adenocarcinoma. Carcinoembryonic antigen (CEA) has not been immunohistochemically detected in mesothelioma. In pleural effusions due to malignant mesothelioma, very low concentrations of SP-A and CEA can be expected. We studied the value of combined...
Adenocarcinoma of the lung is the most common form of lung cancer in nonsmokers. It is commonly seen in the periphery of the lungs. Myasthenia gravis is generally associated with mediastinal malignancies and rarely associated with adenocarcinoma of the lung. We present a case of a 38-year-old male nonsmoker with rapidly progressive adenocarcinoma of the lung associated with myasthenia gravis, a...
