Jason M. Karch

Jason M. Karch serves as Assistant Professor in the Department of Integrative Physiology at Baylor College of Medicine, Houston, where he directs the Karch Laboratory focused on mechanistic manipulation of cell death pathways. His research addresses how aberrant cell death underpins ischemic injuries, degenerative diseases, cancer, and aging, with particular emphasis on cardiac pathologies.

Dr. Karch completed his educational training with a BA in Biology from Dakota Wesleyan University (2005) followed by a PhD in Cell and Cancer Biology from the University of Cincinnati (2012). His doctoral work established the foundation for his current investigations into mitochondrial regulation of cell death.

Research Focus: The Karch Laboratory investigates regulated necrotic cell death mechanisms, specifically targeting the mitochondrial permeability transition pore (MPTP) in cardiomyocyte death during ischemic events. Using genetically engineered mouse models and cell culture systems, the lab identifies molecular components of the MPTP and discovers novel regulators of necrotic pathways through genome-wide screening approaches. Key projects include molecular identification of the MPTP pore-forming component and validation of 306+ candidate genes that modulate necrotic cell death.

Analysis of Dr. Karch's publication record (2022-2025) reveals consistent thematic focus on mitochondrial dysfunction in cardiac pathology. His work bridges fundamental molecular mechanisms with translational applications, demonstrating how MPTP regulation intersects with ischemic injury, muscular dystrophy, aging, and arrhythmogenesis. Recent studies highlight the adenine nucleotide translocase family, ATAD3 protein, and calcium-mediated inter-organellar crosstalk as critical therapeutic targets.

No major scientific awards or fellowships were documented in available sources.

As principal investigator, Dr. Karch oversees two primary research streams: (1) Molecular characterization of the MPTP using genetic and biochemical approaches, and (2) High-throughput screening to identify novel necrosis regulators. His lab employs techniques including calcium retention assays, mitochondrial swelling measurements, and in vivo validation of candidate genes in disease models. Current projects focus on translating basic discoveries into cardioprotective strategies for ischemia-reperfusion injury and muscular dystrophy.

The Karch Laboratory operates within Baylor College of Medicine's research infrastructure, utilizing advanced technology cores for mitochondrial function analysis and collaborating with cardiovascular research groups. The lab maintains active projects on mitochondrial permeability transition in cardiac ischemia, muscular dystrophy, and aging-related heart failure, with emphasis on identifying druggable targets within cell death pathways.
