The heart, being an organ with very low regenerative capacity and high metabolic activity, is vulnerable to chronic, although low-grade, MA. To systematically characterize the effect of low-grade MA on the heart, we treated male and female mice with NH4Cl supplementation for 2 weeks and analyzed their blood chemistry and transcriptomic signature of the heart tissue. The reduction of pH and plasma bicarbonate levels without an associated change in anion gap indicated a physiological manifestation of low-grade MA with minimal respiratory compensation. On transcriptomic analysis, we observed changes in cardiac-specific genes with significant gender-based differences due to MA. We found many genes contributing to dilated cardiomyopathy to be altered in males, more than in females, while cardiac contractility and Na\/K\/ATPase-Src signaling were affected in the opposite way. Our model presents a systems-level understanding of how the cardiovascular tissue is affected by MA. As low-grade MA is a common ailment with many dietary and pharmaceutical interventions, our work presents avenues to limit chronic cardiac damage and disease manifestation, as well as highlighting the sex differences in MA-induced cardiovascular damage.<\/jats:p>","DOI":"10.3390\/metabo13040549","type":"journal-article","created":{"date-parts":[[2023,4,12]],"date-time":"2023-04-12T02:57:08Z","timestamp":1681268228000},"page":"549","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Metabolic Acidosis Results in Sexually Dimorphic Response in the Heart Tissue"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0031-7799","authenticated-orcid":false,"given":"Yamin","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, University of Connecticut Health, Farmington, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amina","family":"Atiq","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Connecticut Health, Farmington, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Peterson","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Connecticut Health, Farmington, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3306-7220","authenticated-orcid":false,"given":"Mikayla","family":"Moody","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Connecticut Health, Farmington, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashkan","family":"Novin","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Connecticut Health, Farmington, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alix C.","family":"Deymier","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Connecticut Health, Farmington, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2877-234X","authenticated-orcid":false,"given":"Junaid","family":"Afzal","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Medicine, University of California San Francisco, San Francisco, CA 94158, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Kshitiz","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Connecticut Health, Farmington, CT 06032, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"274","DOI":"10.1038\/nrneph.2010.33","article-title":"Metabolic acidosis: Pathophysiology, diagnosis and management","volume":"6","author":"Kraut","year":"2010","journal-title":"Nat.
