To understand its response to antibiotic-induced stress, we integrated transcriptomic data from various antibiotics (amikacin sulfate, ciprofloxacin, polymyxin-B, and meropenem) with metabolic modeling techniques. Key metabolic pathways, including arginine and proline metabolism, glycine\u2013serine and threonine metabolism, glyoxylate and dicarboxylate metabolism, and propanoate metabolism, were significantly impacted by all four antibiotics across multiple strains. Specifically, biotin metabolism was consistently down-regulated under polymyxin-B treatment, while fatty acid metabolism was perturbed under amikacin sulfate. Ciprofloxacin induced up-regulation in glycerophospholipid metabolism. Validation with an independent dataset focusing on colistin treatment confirmed alterations in fatty acid degradation, elongation, and arginine metabolism. By harmonizing genetic data with metabolic modeling and a metabolite-centric approach, our findings offer insights into the intricate adaptations of A. baumannii under antibiotic pressure, suggesting more effective strategies to combat antibiotic-resistant infections.<\/jats:p>","DOI":"10.3390\/life14091102","type":"journal-article","created":{"date-parts":[[2024,9,2]],"date-time":"2024-09-02T03:45:21Z","timestamp":1725248721000},"page":"1102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Deciphering Antibiotic-Targeted Metabolic Pathways in Acinetobacter baumannii: Insights from Transcriptomics and Genome-Scale Metabolic Modeling"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1980-5071","authenticated-orcid":false,"given":"Fatma Zehra","family":"Sar\u0131","sequence":"first","affiliation":[{"name":"Institute of Biotechnology, Gebze Technical University, Gebze 41400, Kocaeli, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8262-4420","authenticated-orcid":false,"given":"Tunahan","family":"\u00c7ak\u0131r","sequence":"additional","affiliation":[{"name":"Institute of Biotechnology, Gebze Technical University, Gebze 41400, Kocaeli, T\u00fcrkiye"},{"name":"Department of Bioengineering, Gebze Technical University, Gebze 41400, Kocaeli, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kyriakidis, I., Vasileiou, E., Pana, Z.D., and Tragiannidis, A.
