This study determined whether expression levels of a panel of biologically relevant microRNAs can be used as prognostic or predictive biomarkers in patients who participated in the International Adjuvant Lung Cancer Trial (IALT), the largest randomized study conducted to date of adjuvant chemotherapy in patients with radically resected non-small cell lung(More)
Fifteen percent of lung cancer cases occur in never-smokers and show characteristics that are molecularly and clinically distinct from those in smokers. Epidermal growth factor receptor (EGFR) gene mutations, which are correlated with sensitivity to EGFR-tyrosine kinase inhibitors (EGFR-TKIs), are more frequent in never-smoker lung cancers. In this study,(More)
The role of human papillomavirus (HPV) in the development of lung and esophageal cancer remains inconclusive, which is in contrast to the established role HPV plays in the development of uterine cervical cancer. One of the reasons for this is the difference among reported HPV infection rates in these cancers. An analysis of 485 lung and esophageal cancers(More)
l-Carnitine is an essential component of mitochondrial fatty acid beta-oxidation and plays a pivotal role in the maturation of spermatozoa within the male reproductive tract. Epididymal plasma contains the highest levels of l-carnitine found in the human body, and initiation of sperm motility occurs in parallel to l-carnitine increase in the epididymal(More)
BACKGROUND The tumor suppressor genes CADM1/TSLC1 and DAL-1/4.1B are frequently inactivated by promoter methylation in non-small cell lung cancer. The proteins they encode, CADM1 and 4.1B, form a complex in human epithelial cells and are involved in cell-cell adhesion. METHODS Expression of CADM1 and 4.1B proteins was examined by immunohistochemistry in(More)
The gene for the human orthologue of mouse epiglycanin, a mucin expressed on mammary carcinoma TA3-Ha cells but not TA3-St cells, was identified by homology search to a mouse epiglycanin cDNA fragment identified by representational difference analysis between TA3-Ha and TA3-St cells. The open reading frame of this gene was cloned from human cervical(More)
c-Met is often overexpressed in non-small cell lung cancer, but it remains unsolved whether its overexpression leads to its activation. We used an antibody specific to phospho-c-Met (Tyr1235) to investigate c-Met activation immunohistochemically in 130 surgically resected lung adenocarcinomas. The expression of c-Met and hepatocyte growth factor (HGF) was(More)
ING2 (inhibitor of growth family, member 2) is a member of the plant homeodomain (PHD)-containing ING family of putative tumor suppressors. As part of mSin3A-HDAC corepressor complexes, ING2 binds to tri-methylated lysine 4 of histone H3 (H3K4me3) to regulate chromatin modification and gene expression. ING2 also functionally interacts with the tumor(More)
Tumor hypoxia is associated with a malignant phenotype of cancer cells and poor patient prognosis. To investigate the role of hypoxia in tumor progression, we studied the effects of hypoxia in the A549 lung adenocarcinoma cell line. First, we showed that hypoxic treatment decreased cell-cell adhesion and induced a scattering of cancer cells. Concomitant(More)
Solitary lymphangioma of the lung is rare. We report a case of invasive lymphangioma of the lung, diagnosed in a 9-year-old girl who presented with intractable hemoptysis and a large pulmonary mass, 10 cm in diameter. We performed left lower lobectomy and lingular segmentectomy to remove the mass completely and the patient has been well for 3 years since.(More)
