Background: Higher blood pressure and albuminuria are found in offspring of mothers who smoke during pregnancy. Whether or not kidney development is affected by maternal smoking is unknown.
Methods: Sprague-Dawley rats were randomly allocated to twice-daily cigarette smoke and nicotine condensate (1 mg/kg) or vehicle at day 10 of pregnancy until delivery.
Results: Exposed offspring did not differ from control offspring with respect to body weight, kidney weight, albuminuria, and creatinine clearance. Both male and female offspring had higher tail-plethysmographic blood pressures and lower mean glomerular volume, podocyte, mesangial-cell, and endothelial-cell number, compared to control offspring.
Conclusions: The data document that prenatal exposure to cigarette-smoke condensate containing nicotine influences normal kidney development and could predispose to higher blood pressures later in life.

Purpose: Even though smoking is associated with lung cancer, the exact molecular pathways that link carcinogens with inflammation and oncogenic transformation are not well elucidated. Two major carcinogens in cigarette smoke, Nicotine-derived nitrosamine ketone, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and benzo(α)pyrene (BaP) have not been tested in models that mimic inhaled exposure for prolonged periods of time.
Experimental Design: ICR mice were treated with intratracheal delivery of NNK and BaP (NB) for 18 months.

Background: Although copper oxide nanoparticles (CuONPs) offer certain benefits to humans, they can be toxic to organs and exacerbate underlying diseases upon exposure. Chronic obstructive pulmonary disease (COPD), induced by smoking, can worsen with exposure to various harmful particles. However, the specific impact of CuONPs on COPD and the underlying mechanisms remain unknown.

Background/purpose: Oral cancer is one of the most prevalent malignant tumors in Taiwan. Due to the heterogeneity of oral cancer cells, the five-year survival rate of patients is only 50%. Post-translational modifications contribute to protein diversity and directly influence cell functions.

This systematic review aims to highlight the molecular mechanisms by which whole cigarette smoke affects oral carcinogenesis and its progression in human oral cells, based on evidence from original research articles published in the literature. A literature search was conducted using three databases: Web of Science, Scopus, and PubMed from May to June 2024. The articles were screened, and the data were extracted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines (2020).
