Structural, Functional and Molecular Impact on the Cardiovascular System in ApoE-/- Mice Exposed to Aerosol from modified risk tobacco products, the Carbon Heated Tobacco Product 1.2 and the Tobacco Heating System 2.2 compared to Cigarette Smoke effects (miRNA data).

ABSTRACT: AIM: To investigate the molecular, structural, and functional impact of aerosols from two heat-not-burn-based MRTPs, the Carbon Heated Tobacco Product (CHTP) 1.2 and Tobacco Heating System (THS) 2.2, compared with that of cigarette mainstream smoke (CS) on the cardiovascular system of ApoE-/- mice. METHOD: Female ApoE-/- mice were exposed to aerosols from THS 2.2 and CHTP 1.2 or to CS from 3R4F for up to 6 months at matching nicotine concentrations. A cessation and a switching group (3 months exposure to 3R4F CS followed by filtered air or CHTP 1.2 for 3 months) were included. Cardiovascular effects were investigated using echocardiography, histopathology, immunohistochemistry, and transcriptomics. RESULTS: Continuous exposure to aerosols from CHTP 1.2 and THS 2.2 did not affect the athero
