Addiction (Abingdon, England)

Chenoweth MJ, Peng AR, Zhu AZX, Cox LS, Nollen NL, Ahluwalia JS, Benowitz NL, Knight J, Swardfager W, Tyndale RF.
PMID: 34791718
Addiction. 2021 Nov 17; doi: 10.1111/add.15742. Epub 2021 Nov 17.

BACKGROUND AND AIMS: CYP2B6, a genetically variable enzyme, converts bupropion to its active metabolite hydroxybupropion. CYP2B6 activity and bupropion-aided cessation differ between women and men. The aim of this study was to determine whether genetically normal (versus reduced) CYP2B6...

Reappraising Choice in Addiction: Novel Conceptualizations and Treatments for Tobacco Use Disorder.

Nicotine & tobacco research : official journal of the Society for Research on Nicotine and Tobacco

Palmer AM, Toll BA, Carpenter MJ, Donny EC, Hatsukami DK, Rojewski AM, Smith TT, Sofuoglu M, Thrul J, Benowitz NL.
PMID: 34270729
Nicotine Tob Res. 2022 Jan 01;24(1):3-9. doi: 10.1093/ntr/ntab148.

The introduction of alternative nicotine and tobacco products (such as e-cigarettes, heat-not-burn devices, nicotine pouches) warrants an updated framework from which to conceptualize tobacco use disorder (TUD). The following review provides considerations for TUD within the context of novel...

Nicotine delivery and cigarette equivalents from vaping a JUULpod.

Tobacco control

PMID: 33762429
Tob Control. 2021 Mar 24; doi: 10.1136/tobaccocontrol-2020-056367. Epub 2021 Mar 24.

With patented nicotine salt technology, JUUL dominates the e-cigarette market. We reviewed studies of JUUL's nicotine pharmacokinetic profile and studies quantifying nicotine in a JUULpod, emitted in the aerosol and absorbed by users. Examined in eight studies, JUUL's peak...

Effect of race and glucuronidation rates on the relationship between nicotine metabolite ratio and nicotine clearance.

Pharmacogenetics and genomics

Liakoni E, Tyndale RF, Jacob P, Dempsey DA, Addo N, Benowitz NL.
PMID: 33675323
Pharmacogenet Genomics. 2021 Jul 01;31(5):97-107. doi: 10.1097/FPC.0000000000000427.

OBJECTIVES: To investigate if the nicotine metabolite ratio (NMR, the ratio of nicotine metabolites 3'-hydroxycotinine/cotinine) is a reliable phenotypic biomarker for nicotine clearance across races, and as a function of differences in the rate of nicotine, cotinine and 3'-hydroxycotinine...

Determination of 4-(Methylnitrosamino)-1-(3-Pyridyl)-1-Butanone (NNK) arising from tobacco smoke in airborne particulate matter.

Environment international

Aquilina NJ, Havel CM, Harrison RM, Ho KF, Benowitz NL, Jacob Iii P.
PMID: 34991253
Environ Int. 2022 Jan;158:106992. doi: 10.1016/j.envint.2021.106992. Epub 2021 Nov 19.

The most important tobacco-specific nitrosamine found in cigarette smoke and formed in ageing smoke after cigarettes are extinguished is 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). It is formed from nitrosation of nicotine, under particular conditions both in indoor and outdoor environments. NNK has...

Post-transcriptional regulation of GAP-43 rnRNA levels during neuronal differentiation and nerve regeneration.

Molecular and cellular neurosciences

Perrone-Bizzozero NI, Neve RL, Irwin N, Lewis S, Fischer I, Benowitz LI.
PMID: 19912825
Mol Cell Neurosci. 1991 Oct;2(5):402-9. doi: 10.1016/1044-7431(91)90027-l.

The expression of GAP-43 is a well-characterized correlate of the growth and reorganization of neural connections. Although the expression of this protein is known to depend on the levels of the mRNA, the mechanisms that control the latter are...

Correlates of NNAL levels among nondaily and daily smokers in the college student population.

Current biomarker findings

Berg CJ, Schauer GL, Ahluwalia JS, Benowitz NL.
PMID: 24298447
Curr Biomark Find. 2012 Oct 15;2012(2). doi: 10.2147/CBF.S34642.

INTRODUCTION: Recent simultaneous increases in nondaily smoking and decreases in daily smoking make the identification of nondaily smokers through biomarker measures as well as the relationship of biomarker levels to smoking behaviors important topics. However, little is known about...

Gender differences in the pharmacology of nicotine addiction.

Addiction biology

Addict Biol. 1998 Oct;3(4):383-404. doi: 10.1080/13556219871930.

Smoking rates have declined in recent years less rapidly in women than in men. More adolescent girls than boys are currently smoking. Quitting smoking is reported in many studies to be more difficult in women than in men. These...

Tunneling Nanotubes and Gap Junctions-Their Role in Long-Range Intercellular Communication during Development, Health, and Disease Conditions.

Frontiers in molecular neuroscience

Ariazi J, Benowitz A, De Biasi V, Den Boer ML, Cherqui S, Cui H, Douillet N, Eugenin EA, Favre D, Goodman S, Gousset K, Hanein D, Israel DI, Kimura S, Kirkpatrick RB, Kuhn N, Jeong C, Lou E, Mailliard R, Maio S, Okafo G, Osswald M, Pasquier J, Polak R, Pradel G, de Rooij B, Schaeffer P, Skeberdis VA, Smith IF, Tanveer A, Volkmann N, Wu Z, Zurzolo C.

Cell-to-cell communication is essential for the organization, coordination, and development of cellular networks and multi-cellular systems. Intercellular communication is mediated by soluble factors (including growth factors, neurotransmitters, and cytokines/chemokines), gap junctions, exosomes and recently described tunneling nanotubes (TNTs). It...
