Lung cancer is among the highly prevalent and deadly cancers in the United States and worldwide. Cells that are cancerous exhibit higher rates of glycolysis as compared to normal cells. In an attempt to exploit this uniquely enhanced glucose-dependent ATP generation phenomenon, the authors hypothesize that exposure of cancer cells to normal organic metabolites that are capable of inhibiting gly...

Background and Aim: Morphine is frequently used for patients suffering cancer in their end stages to relive pain. However, there are conflicting reports suggesting morphine to promote tumor growth and reduce survival rate in cancerous animal models or induce necrosis and apoptosis in the tumor cells. In the present study, we studied the effect of morphine on proliferation of human lung adenocar...

transforming growth factor-beta (tgf-β) is one of the most important cytokines implicated in growth, differentiation, repair and also the pathogenesis of the lung fibrosis by its stimulatory effect on extracellular matrix deposition. pulmonary epithelial cells are considered as a source of tgf-β in lung. substance p (sp), as a neuroimmunomodulator has elevated levels in inflamed airways and alt...

The segmentation, detection and extraction of the infected tumor from Magnetic Resonance Imaging (MRI) images are key concerns for radiologists or clinical experts. But it is tedious time consuming its accuracy depends on their experience only. This paper suggest a new methodology recognition, classification different types cancer cells both MRI RGB (Red, Green, Blue) performed using supervised...

Surfactant proteins play important roles in lung surfactant function and innate immunity. The DNA methylation state of 11 CpG sites of surfactant protein (SP)-A1, -B, -C, and -D was determined using universal bead arrays. A total of 90 cancerous and non-cancerous tissues from 23 patients with adenocarcinoma and 22 with squamous cell carcinoma were studied. These were divided into a training set...

OBJECTIVE The primary goal of this study was to determine the difference of abundance of CD4+, CD8+ and CD56+ bronchoalveolar fluid's lymphocytes and their subpopulations between cancerous lung and healthy lung from the same patient. METHODS Mini-bronchoalveolar lavage was taken from 55 patients from lung with cancer and healthy lung. After laboratory processing and addition of CD4, CD8, CD27...

The aim of this study was to clarify the significance of DNA methylation alterations at precancerous stages of lung adenocarcinoma. Using single-CpG resolution Infinium array, genome-wide DNA methylation analysis was performed in 36 samples of normal lung tissue obtained from patients without any primary lung tumor, 145 samples of non-cancerous lung tissue (N) obtained from patients with lung a...

An increasing number of reports have shown that diverse microRNAs are involved in tumorigenesis and tumor progression. We performed this study to identify novel miRNAs that may be involved in lung cancer and study on their functions. We tested the expression of 450 miRNAs in lung tumor tissues and adjacent non-cancerous tissues. We found that miRNA-545 was less abundant in cancerous lung tissue...

Background: Radiotherapy is the gold standard in the treatment of lung cancer. However, the radiosensitization of cancerous cells requires further improvement. Here, we investigated the effect of dihydroartemisinin (DHA) on the radiosensitization of non-small cell lung cancer (NSCLC) cells. Methods: Cell proliferation and cell cycle assays were carried out using A549 cells exposed to DHA. The e...
