Altered expression of MUC4 plays an oncogenic role in various cancers, including pancreatic, ovarian, and breast. This study evaluates the expression and role of MUC4 in non-small-cell lung cancer (NSCLC).
MUC4 plays a tumor-suppressor role in NSCLC by altering p53 expression in NSCLC. Decrease in MUC4 expression in advanced tumor stages also seems to confirm the novel protective function of MUC4 in NSCLC.

The objective of this research was to identify impact of risk factors on changing trends of lung cancer in a case control study. In the study conducted from 2006 to 2010 the cases included newly diagnosed patients of histological proven lung carcinoma attending the radiotherapy department. Change in trend was observed in patients diagnosed at younger age of 57.48 ± 0.56 years in 2010 with adenocarcinoma unlike 62.89 ± 1.21 years in 2006. Females show increase in incidence of lung cancer in 2010. The “active” smokers and years of smoking were significantly high among cases. The incidence of squamous cell carcinoma declined from 47.4% in 2006 to 15% in 2010 whereas adenocarcinoma increased.

We recently demonstrated that the basic helix-loop-helix transcription factor Twist1 cooperates with mutant Kras to induce lung adenocarcinoma in transgenic mouse models and that inhibition of Twist1 in these models led to Kras-induced senescence. In the current study, we show that silencing of TWIST1 in KRAS mutant human NSCLC cell lines as well as in in EGFR mutation driven and c-Met amplified NSCLC cell lines resulted in dramatic growth inhibition and either activation of a latent oncogene-induced senescence program or in some cases, apoptosis.These findings suggest that silencing of TWIST1 in oncogene driver dependent NSCLC represents a novel and promising therapeutic strategy.
CollabRx, Inc. announced the release of a new version of its Therapy Finder™application (“app”) for lung cancer. The lung cancer Therapy Finder™app is a web-based decision support tool that enables oncologists to take into account the genetics of a patient’s tumor when determining a treatment plan. The newest lung cancer Therapy Finder™ is currently freely available at the company’s website and via distribution partners such as MedPage Today, Everyday Health’s physician portal.
Oncolytics Biotech Inc said a mid-stage trial of its experimental lung cancer drug showed that 95 percent of the patients experienced a reduction in the size of their tumors. The drug, Reolysin, was used intravenously in combination with chemotherapy drugs carboplatin and paclitaxel. It was tested on patients suffering from metastatic or recurrent squamous cell carcinoma of the lung.

Evidence from human and animal research indicates that choline metabolic pathways may be activated during a variety of diseases, including cancer. We report results of a case-control study of 2821 lung cancer cases and 2923 controls that assessed associations of choline and betaine dietary intakes with lung cancer. Our results suggest that choline and betaine intake, especially higher betaine intake, may be protective against lung cancer through mitigating the adverse effect of smoking.

RNA-dependent protein kinase (PKR) is an independent prognostic variable in patients with non-small-cell lung cancer (NSCLC). In the current study, we investigated the correlation between PKR and 25 other biomarkers for NSCLC, identified the markers that could further improve the prognostic significance of PKR and elucidated the mechanisms of interaction between these markers and PKR.
PKR/EphA2 is a significant predictor of prognosis for NSCLC. PKR/EphA2 may be a promising approach to improving screening efficiency and predicting prognosis in patients with NSCLC.

We evaluated the in-vivo anticancer activity of aerosolized Celecoxib encapsulated Nanolipidcarriers (Cxb-NLC) as a single therapeutic agent and combined with intravenously administered Docetaxel (Doc) against non-small cell lung cancer. Combination therapy with Cxb-NLC and Doc showed significant reduction in tumor growth which was further confirmed by proteomic analysis.
