Article Title: A Transient Increase in Cardiomyocyte Protein O-GlcNAcylation Enhances Susceptibility to Pressure Overload-Induced Cardiac Remodeling

doi: 10.1101/2025.06.04.657956

Figure Lengend Snippet: Schematic showing the experimental timeline and procedures for the dnOGAh ON/OFF-TAC paradigm used in this study—from induction of dnOGA transgene via DOX, switching the transgene “off” via removal of DOX, and TAC procedure, to subsequent echocardiography and tissue harvesting for downstream analyses.

Article Snippet: At the prespecified timepoints shown in the experimental schema ( ) after 8 weeks of TAC/Sham, transthoracic echocardiography was performed on all mice in the study, as previously described., In brief, the mice were anesthetized via 2% isoflurane induction chamber inhalation then placed in a supine position on a heated echocardiography platform (Vevo integrated rail system, VisualSonics) set at 37°C to maintain body temperature; sedation was maintained via nose cone inhalation of 1.0-1.5% isoflurane which allowed for heart rate maintenance of ∼400 beats / min. Fur from the chest was removed via topical depilatory cream, and then the mice were then placed in a left-lateral-decubitus position.

Figure Lengend Snippet: A) Normalized ratio of wet-dry lung weight to TL for Con-TAC and ON/OFF-TAC mice compared to age-matched Sham controls (Con-Sham and ON/OFF-Sham) ( n ≥ 29). B) Normalized ratio of wet-dry lung weight to TL for Con-TAC and ON/OFF-TAC mice compared to age-matched Sham controls (Con-Sham and ON/OFF-Sham) split by sex. C-G) Cardiac function measures via echocardiography split by sex for: cardiac systolic function as measured by LV ejection fraction from M-mode LV traces ( C ), stroke volume from M-mode LV traces ( D ), left ventricular internal dimension at diastole (LVIDd) ( E ), cardiac wall thickening as measured by LV posterior wall thickness at diastole (LVPWd) ( F ), and inter-ventricular septum thickness at diastole (IVSd) ( G ). Statistical significance was based on two-way ANOVA followed by Tukey’s multiple comparisons test (* p < 0.05, ** p < 0.01, *** p < 0.005). All calculated and analysis data are mean ± S.E.M.
