Article Abstract
Lung cancer is one of the commonest cancers detected worldwide with a high mortality rate. The responsible factors affecting survival include delayed prognosis, and lack of effective treatments. To help improve the disease management, there is a need for better screening and development of specific markers that help in the early diagnosis. Analysis of differentially expressed proteins in cancer cells in comparison to their normal counterparts using proteome profiling revealed identification of new biomarkers as therapeutic targets. Therefore, an animal model for lung cancer was developed and monitored by histopathological evaluation. Lung tissue proteins were isolated, solubilized and resolved on 2D gel electrophoresis using broad pH range IPG strips (pH 3-10). Liquid chromatography and mass spectrometry (LC-MS/MS) revealed 66 proteins to be differentially expressed in cancer tissue as compared to normal. The study identified and characterized three of these proteins, namely peroxiredoxin-6, β-actin and collagen α-1 (VI) as potentially prospective biomarkers for early detection of lung cancer.

Background: Rare genetic variation provided by whole genome sequence datasets has been relatively less explored for its contributions to human traits. Meta-analysis of sequencing data offers advantages by integrating larger sample sizes from diverse cohorts, thereby increasing the likelihood of discovering novel insights into complex traits. Furthermore, emerging methods in genome-wide rare variant association testing further improve power and interpretability.

Background: Surgical resection is the cornerstone for early-stage non-small cell lung cancer (NSCLC), with lobectomy historically standard. Evolving techniques have spurred debate comparing lobectomy and segmentectomy. This study analyzed early postoperative patient-reported symptoms and functional status in patients with early NSCLC undergoing either procedure.

Radon (Rn) is a naturally occurring radioactive gas produced by the decay of uranium-bearing minerals in rocks and soils. Long-term exposure to elevated radon levels in drinking water is associated with an increased risk of stomach and lung cancers. This study aims to assess the concentration of radon in groundwater and evaluate its potential health risks in six cancer-affected districts, i.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

Lung adenocarcinoma (LUAD) associated with usual interstitial pneumonia (UIP) harbours distinct features compared to lung adenocarcinoma without UIP. Therefore, we aimed to characterise the tumour microenvironment of LUAD with UIP by focusing on cancer-associated fibroblasts (CAFs) and stromal composition. Immunohistochemistry was performed on 32 LUAD samples (16 each with and without UIP) to evaluate CAF marker expression and lymphocyte infiltration.
