The present study is designed to assess the mitochondrial status during benzo(a)pyrene (B(a)P)-induced lung carcinogenesis in Swiss albino mice and to reveal the modulatory effect of hesperidin over it. B(a)P (50 mg/kg body weight)-induced mitochondrial abnormalities was evident from alterations in mitochondrial lipid peroxides, antioxidant status (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione-S-transferase, reduced glutathione, vitamin E, and vitamin C), major tricarboxylic acid (TCA) cycle enzyme activities (isocitrate dehydrogenase, succinate dehydrogenase, malate dehydrogenase, alpha-ketoglutarate dehydrogenase), electron transport chain (ETC) complexes activities and ATP levels. Ultrastructural changes in lung mitochondria were also in accord with the above aberrations. Hesperidin (25 mg/kg body weight) supplementation effectively counteracted all the above changes and restored cellular normalcy, indicating its protective role during B(a)P-induced lung cancer.

Purpose: Lung cancer is currently the most common malignant tumor worldwide and one of the leading causes of cancer-related deaths, posing a serious threat to human health. MicroRNAs (miRNAs) are a class of endogenous non-coding small RNA molecules that regulate gene expression and are involved in various biological processes associated with lung cancer. Understanding the mechanisms of lung carcinogenesis and detecting disease biomarkers may enable early diagnosis of lung cancer.

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.

Small-cell lung cancer (SCLC), an aggressive neuroendocrine tumor strongly associated with exposure to tobacco carcinogens, is characterized by early dissemination and dismal prognosis with a five-year overall survival of less than 7%. High-frequency gain-of-function mutations in oncogenes are rarely reported, and intratumor heterogeneity (ITH) remains to be determined in SCLC. Here, via multiomics analyses of 314 SCLCs, we found that the ASCL1/MKI67 and ASCL1/CRIP2 clusters accounted for 74.

Non-small cell lung cancer (NSCLC) remains a leading cause of cancer-related mortality, with "epidermal growth factor receptor (EGFR)" mutations playing a pivotal role in tumor progression and carcinogenesis. "Third-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs)," such as Osimertinib, have significantly improved treatment outcomes by overcoming resistance mechanisms like the T790M mutation. However, Osimertinib's clinical application is limited by cardiotoxicity concerns, necessitating safer alternatives.

Background: Red and processed meat consumption is extensively linked to chronic disease risk in observational studies, with robust meta-analyses demonstrating significant positive associations for colorectal, breast, endometrial, and lung cancers, type 2 diabetes (T2DM), cardiovascular disease (CVD), and all-cause mortality. Dose-response relationships indicate elevated risks even at moderate intakes. Moreover, processed meats consistently show stronger detrimental effects than unprocessed red meats.
