The Claim
Exposure to saturated and trans fatty acids increases cytosolic HMGB1 and oxidative stress in human induced pluripotent stem cell-derived cardiomyocytes and neonatal rat cardiomyocytes, and this increase is prevented by inhibition of calpain-1 or reactive oxygen species.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In heart muscle cells derived from human stem cells and from newborn rats, saturated and trans fatty acids raise levels of HMGB1 protein and oxidative stress markers, and blocking calpain-1 or reactive oxygen species stops this increase.
See the scientific wording
In human induced pluripotent stem cell-derived cardiomyocytes and neonatal rat cardiomyocytes, exposure to saturated and trans fatty acids increases cytosolic HMGB1 and oxidative stress, which is prevented by inhibition of calpain-1 or reactive oxygen species.
When heart cells are exposed to unhealthy fats, an enzyme called calpain-1 becomes more active, which causes the mitochondria to produce more harmful reactive molecules. These molecules change the structure of a protein called HMGB1, forcing it to move out of the nucleus and into the cell's main body. Once outside the nucleus, HMGB1 is released from the cell and triggers inflammation in nearby immune cells.
What the research says
1 studyWhen heart cells are exposed to unhealthy fats, they get stressed and release a harmful protein called HMGB1—but blocking either the stress or a specific enzyme (calpain-1) stops this from happening. The study proves this works in both human and rat heart cells.
