Myocardial reperfusion (R) is provided with an effective and rapid treatment; however, it can lead to fatal results, as well as ischemia (I). This study aims to use proteomic analysis to assess proteins and pathways in H9C2 cardiomyoblast cells exposed to hypoxic conditions, followed by reoxygenation, representing I/R injury for both short and long terms, reflecting acute and chronic hypoxia, respectively. Utilizing advanced techniques, our goal is to identify and characterize key proteins undergoing alterations during these critical phases.<h4>Materials and methods</h4>H9C2 cardiomyoblasts, a commonly used cell line for simulating in vivo I/R damage, were exposed to Turkish journal of biology = Turk biyoloji dergisi192-202https://www.ebi.ac.uk/biostudies/studies/S-EPMC11265846biostudies-literatureProteomic investigation of acute and chronic hypoxia/reoxygenation responsive proteins and pathways in H9C2 cardiomyoblasts.PMC11265846Oztug Durer ZAKilinc EOztug MBaloglu EfalseProteomic investigation of acute and chronic hypoxia/reoxygenation responsive proteins and pathways in H9C2 cardiomyoblasts.<h4>Background/aim</h4>Ischemic heart diseases continue to be a significant global cardiovascular problem in today's world.
