Claim 1 of 7Not checkedResearchers have found a unique cell-level difference that helps keep heart muscle fueled up: the ability to burn glucose in the cytosol while burning lactate in the mitochondria.View evidenceHide evidence

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.
Claim 2 of 7Not checkedThis spatial separation allows both energy-generating reactions to happen simultaneously, helping keep the heart fueled up no matter the energy source.View evidenceHide evidence

Claim 3 of 7Not checkedThe article says the process is mostly dispensable to daily life but crucial to preventing heart failure when the heart is stressed.View evidenceHide evidence
As statedmostly dispensable to daily life
Not checked
No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.
Claim 4 of 7Not checkedThe separation between glucose and lactate metabolism depends on MCT1, which moves lactate to the inside of the mitochondria.View evidenceHide evidence
Not checked
No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.
Claim 5 of 7Not checkedGenetic mutations in MCT1 prevent lactate from entering the mitochondria and disrupt the heart's energy balance, leading to heart failure when stressed.View evidenceHide evidence

Claim 6 of 7Not checkedThe article says the findings uncover a new requirement for lactate to fuel the injured heart and suggest new therapeutic targets to re-energize the heart during heart failure.View evidenceHide evidence
