conclusion the technical performance of pet scan is significantly higher than similar technologies for staging and treatment of nsclc. in addition, it might slightly improve the treatment process and lead to a small level of increase in the quality adjusted life year (qaly) gained by these patients making it cost-effective for the treatment of nsclc. results the total annual running cost of a p...

among the drug delivery and targeting (ddt) routes, lung alveolar epithelium has been given enormous attentions in terms of the delivery of a wide range of macromolecules such as gene- or protein-based nanopharmaceuticals. however, little is known about cellular modulation of lung transport characteristics by endogenous and/or exogenous agents. thus, in the current study, impact of dexamethason...

Histone deacetylase (HDAC) activity is one of the widely used and well-established mechanisms for regulation of various genes in cancer. To identify which subtype of class I HDACs are overexpressed in cancers, we analyzed the expression of class I HDAC isotypes composed of HDAC1, 2, 3 and 8 in several cell lines and human cancer tissues, including cancer of the stomach, esophagus, colon, prosta...

We used MethyLight assays to analyze DNA methylation status of 27 genes on 49 paired cancerous and noncancerous tissue samples from non-small cell lung cancer (NSCLC) patients who underwent surgical resection. Seven genes (RARB, BVES, CDKN2A, KCNH5, RASSF1, CDH13, and RUNX) were found to be methylated significantly more frequently in tumor tissues than in noncancerous tissues. Only methylation ...

Mass spectrometry-based clinical proteomic analysis, combined with collection of taegeted cancerous cells laser-microdissected (LMD) from formalin-fixed paraffinembedded (FFPE) tissues, has been promising to unveil both proteins expressed and their functional networks in lung cancer subtypes. Among lung cancer subtypes, both large cell neuroendocrine carcinoma (LCNEC) of the lung and small cell...

Although the incidence of small cell lung cancer (SCLC) has declined during the past 30 years, it remains a frustrating disease to research and treat. Numerous attempts to enhance the anti-tumor effects of traditional chemotherapy for SCLC have not been successful. For any tumor to become cancerous, various genetic mutations and biologic alterations must occur in the cell that, when combined, r...

The present study investigates the anti-proliferative and apoptosis inducing mechanism of CoCl2·6H2O in PC-3 cancer cell line. Preliminary, three different forms of cobalt i.e., cobaltous (CoCl2·6H2O), macro-Co(II,III) oxide and nano-Co(II,III) oxide were screened for antiproliferative activity in PC-3 cell line. The CoCl2·6H2O being the most effective antiproliferative agent, hence it was furt...

Poor survival rates from lung cancer can largely be attributed to metastatic cells that invade and spread throughout the body. The tumor microenvironment (TME) is composed of multiple cell types, as well as non-cellular components. The TME plays a critical role in the development of metastatic cancers by providing migratory cues and changing the properties of the tumor cells. The Extracellular ...

Recent studies suggest that paired box 5 (PAX5) is down-regulated in multiple tumours through its promoter methylation. However, the role of PAX5 in non-small cell lung cancer (NSCLC) pathogenesis remains unclear. The aim of this study is to examine PAX5 expression, its methylation status, biological functions and related molecular mechanism in NSCLC. We found that PAX5 was widely expressed in ...
