Alcohol consumption has been linked to many diseases and can alter genetic activity. In the present report, we carried out experiments to make clear how alcohols affect the efficiency of transcription-translation (TX-TL) and translation (TL) by adapting cell-free gene expression systems with plasmid DNA and RNA templates, respectively. In addition, we quantitatively analyzed intrachain fluctuations of single giant DNA molecules based on the fluctuation-dissipation theorem to gain insight into how alcohols affect the dynamical property of a DNA molecule. Ethanol (2\u20133%) increased gene expression levels four to five times higher than the control in the TX-TL reaction. A similar level of enhancement was observed with 2-propanol, in contrast to the inhibitory effect of 1-propanol. Similar alcohol effects were observed for the TL reaction. Intrachain fluctuation analysis through single DNA observation showed that 1-propanol markedly increased both the spring and damping constants of single DNA in contrast to the weak effects observed with ethanol, whereas 2-propanol exhibits an intermediate effect. This study indicates that the activation\/inhibition effects of alcohol isomers on gene expression correlate with the changes in the viscoelastic mechanical properties of DNA molecules.<\/jats:p>","DOI":"10.3390\/polym15010149","type":"journal-article","created":{"date-parts":[[2022,12,29]],"date-time":"2022-12-29T02:52:21Z","timestamp":1672282341000},"page":"149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Activation\/Inhibition of Gene Expression Caused by Alcohols: Relationship with the Viscoelastic Property of a DNA Molecule"],"prefix":"10.3390","volume":"15","author":[{"given":"Kohei","family":"Fujino","sequence":"first","affiliation":[{"name":"Faculty of Life and Medical Sciences, Doshisha University, Kyoto 610-0394, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Nishio","sequence":"additional","affiliation":[{"name":"Faculty of Life and Medical Sciences, Doshisha University, Kyoto 610-0394, Japan"},{"name":"Cluster of Excellence Physics of Life, Technical University of Dresden, 01307 Dresden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keita","family":"Fujioka","sequence":"additional","affiliation":[{"name":"Faculty of Life and Medical Sciences, Doshisha University, Kyoto 610-0394, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuko","family":"Yoshikawa","sequence":"additional","affiliation":[{"name":"Faculty of Life and Medical Sciences, Doshisha University, Kyoto 610-0394, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Kenmotsu","sequence":"additional","affiliation":[{"name":"Faculty of Life and Medical Sciences, Doshisha University, Kyoto 610-0394, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2751-7136","authenticated-orcid":false,"given":"Kenichi","family":"Yoshikawa","sequence":"additional","affiliation":[{"name":"Faculty of Life and Medical Sciences, Doshisha University, Kyoto 610-0394, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1016\/S0959-440X(96)80052-2","article-title":"DNA condensation","volume":"6","author":"Bloomfield","year":"1996","journal-title":"Curr.
