Partitioning defective protein 3 (Par3) can activate the Tiam1/Rac pathway to inhibit invasion and metastasis in many cancers; however, the role of Par3 in lung adenocarcinoma remains unknown. Here we show that Par3 is downregulated in lung adenocarcinoma tissues and is associated with higher rates of lymph node metastasis and recurrence. Our functional study demonstrated that knock-down of Par...

Human telomerase reverse transcriptase (hTERT) is the catalytic subunit and the activity determinant factor of the telomerase enzyme which maintains the length of human chromosomes. In recent years it has become an attractive molecular target for cancer gene therapy. In the present study, we show that hTERT siRNA effectively suppressed the expression of hTERT mRNA and hTERT protein levels, redu...

Human complement factor H (CFH), a central complement control protein, is a member of the regulators of complement activation family. Recent studies suggested that CFH may play a key role in the resistance of complement-mediated lysis in various cancer cells. In this study, we investigated the role of CFH in human lung cancer. Expression of CFH was analyzed in lung cancer cell lines by RT-PCR, ...

The Hippo pathway and its downstream transcriptional co-activator Yap influence lung cancer, but the nature of the Yap contribution has been unclear. Using a genetically engineered mouse lung cancer model, we show that Yap deletion completely blocks KrasG12D and p53 loss-driven adenocarcinoma initiation and progression, whereas heterozygosity for Yap partially suppresses lung cancer growth and ...

Asthma, chronic obstructive pulmonary disease (COPD), and pulmonary tuberculosis (TB) are common lung diseases associated with lung cancer mortality. This study evaluated sex disparities in pre-existing pulmonary diseases and stage-dependent lung adenocarcinoma survival.Patients newly diagnosed with lung adenocarcinoma between 2003 and 2008 were identified using the National Health Insurance Re...

BACKGROUND Serum carcinoembryonic antigen (CEA) is often elevated in lung adenocarcinoma, but not in all patients. Meanwhile, epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) fusion protein are the main driving forces in lung adenocarcinoma. However, whether CEA levels are associated with histologic subtype, EGFR mutations, and ALK fusion remain largely unc...

PURPOSE This study aimed to determine the relationship between ALK status and lung adenocarcinoma subtypes, according to the IALSC/ATS/ERS classification in Chinese patients. METHODS A reclassification of 2299 surgically resected lung adenocarcinomas was performed, and ALK status was detected by immunohistochemistry (Ventana Medical Systems) in Shanghai Chest Hospital. RESULTS ALK rearrange...

Activating KRAS mutations in lung adenocarcinoma are characterized with treatment resistance and poor prognosis. As a small molecule inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase, apatinib has been proven successful in advanced gastric cancer and breast cancer. In this study, we show the result of apatinib as salvage treatment in lung adenocarcinoma patien...

Systemic therapy for salivary gland carcinoma (SGC) is indicated recurrent and/or metastatic (RM) disease. The background, goals of therapy, organ function, symptomatic or a symptomatic, and histopathology should be considered in each case. Adenoid cystic with only lung metastasis often progresses slowly many cases are followed up without whereas duct carcinoma, adenocarcinoma NOS, adenoid mult...

BACKGROUND The frequency of epithelial cell adhesion molecule (EpCAM) expression was investigated in non-small cell lung cancer (NSCLC) cells and human tissues, and its clinicopathological significance in adenocarcinoma of the lung was evaluated. MATERIALS AND METHODS EpCAM expression was analysed by reverse transcription-polymerase chain reaction (RT-PCR) and flow cytometry in human NSCLC ce...
