Drug resistance and immune deficiency are important factors for the poor prognosis of lung carcinoma. The present study explored the possible protective effect of immune reconstitution from peripheral blood mononuclear cells (PBMCs) on multi-drug-resistant human lung carcinoma Am1010 cells in non-obese diabetic/severe combined immunodeficient (NOD/SCID) mice. The inoculated tumor fragments grew...

We have examined a panel of human lung cancer cell lines for amplification and expression of the c-myc, N-myc, and c-myb oncogenes. The cell lines analyzed represent various histopathological types of lung cancer: small cell carcinoma with neuroendocrine properties; squamous cell carcinoma with epithelial markers; and large cell carcinoma with a mixed neuroendocrine-epithelial phenotype. Two of...

Three new Complexes of formula [pd(bpy)(R-NH-CSS)] Cl (where bpy is 2/2′- bipyridine, and R-NH-CSS is butylamine, hexylamine- and octyamine-dithiocabamate anion) have been synthesized by University of Sistan and Blachostan. These complexes have been characterized by spectroscopic methods such as ultraviolet-visible, infrared and 1H-NMR as well as conductivity measurements and chemical analysis....

Lung cancer is one of the most common malignancies with a high rate of mortality. Lung cancer stem-like cells (CSCs)/ cancer-initiating cells (CICs) play major role in resistance to treatments, recurrence and distant metastasis and eradication of CSCs/CICs is crucial to improve recent therapy. Cytotoxic T lymphocytes (CTLs) are major effectors of cancer immunotherapy, and CTLs recognize antigen...

ADAM28, a member of the ADAM (a disintegrin and metalloproteinase) gene family, is over-expressed by carcinoma cells and the expression correlates with carcinoma cell proliferation and progression in human non-small cell lung and breast carcinomas. To study the molecular mechanisms of ADAM28 gene expression in carcinoma cells, we examined the expression of ADAM28 in MadinDurby canine kidney (MD...

Human lung tumor cell lines established from the major histological types of lung cancer were examined by immunofluorescent staining techniques for their patterns of intermediate filament (keratin, vimentin, and neurofilament triplet protein) expression. All cell lines examined, both small cell lung carcinoma (SCLC) and non-SCLC (squamous cell carcinoma, adenocarcinoma, large cell carcinoma, an...

Heterogeneous nuclear ribonucleoprotein (hnRNP) B1 is a RNA-binding protein of Mr 37,000. We previously reported that hnRNP B1 was specifically overexpressed in the nuclei of human lung cancer cells, particularly in squamous cell carcinoma (E. Sueoka et al., Cancer Res., 59: 1404-1407, 1999). We extended this study to determine whether hnRNP BL was overexpressed in roentgenographically occult c...

Introduction: Cytological evaluation is an important, usually initial diagnostic modality in patients with suspected malignant lung masses. Bronchoscopic washing, bronchoalveolar lavage, bronchial brushing and fine needle aspirations may complement tissue biopsies the diagnosis of cancer. This study was undertaken to compare efficacy wash cytology correlate it histopathology cases cancer at a t...

Recent studies demonstrated that cancer stem cells (CSCs) have higher tumorigenesis properties than those of differentiated cancer cells and that transcriptional factor-SOX2 plays a vital role in maintaining the unique properties of CSCs; however, the function and underlying mechanism of SOX2 in carcinogenesis of lung cancer are still elusive. This study applied immunohistochemistry to analyze ...
