Comparison of Tobacco Use and Cessation Behavior between Conventional Cigarette and Heated Tobacco Product Users: Based on the Analyses of the Eighth Korea National Health and Nutrition Examination Survey 2019.

Background: After the advent of heated tobacco products (HTPs) in 2017, domestic cigarette sales declined until 2019, but have increased in South Korea since 2020. This study aimed to analyze tobacco use and cessation behavior among HTP users compared with conventional cigarette (CC) users.

Methods: We analyzed data from the eighth Korea National Health and Nutrition Examination Survey (2019).

Suppression of Nrf2 attenuates adipogenesis and decreases FGF21 expression through PPAR gamma in 3T3-L1 cells.

Adipogenesis is the process of differentiation from preadipocytes to adipocytes and is orchestrated by various transcription factors, such as the peroxisome proliferator-activated receptor gamma (PPARγ) and the CCAAT-enhancer-binding protein alpha (C/EBPα). Oxidative stress is also a crucial factor in adipogenesis, and adipocyte differentiation is affected by the cellular redox status. The nuclear factor E2-related factor 2 (Nrf2), which is a basic leucine zipper (bZIP) transcription factor, acts as a regulator of cellular oxidative stress.
