Rhein alleviates myocardial ischemic injury by inhibiting mitochondrial division, activating mitochondrial autophagy and suppressing myocardial cell apoptosis through the Drp1/Pink1/Parkin pathway.

Oh, behold the wonders of rhein, the botanical knight in shining armor, ready to charge into the treacherous battlefield of acute myocardial infarction (AMI) in rats. In a twist that no one saw coming (except maybe everyone with a basic understanding of pharmacology), rhein turns out to have antioxidant and anti-inflammatory properties that might just be the secret sauce for treating various ailments. But wait, there’s a catch – we’re not entirely sure how this magic potion works its wonders on the heart. Shocking, I know.
Enter the valiant researchers, armed with their trusty left anterior descending (LAD) ligation technique, to induce AMI in Sprague‒Dawley rats, because why not? These rats were then split into four groups, because variety is the spice of life: a sham group (the lucky ones), an AMI group (the not-so-lucky ones), an AMI + rhein group (the hopeful ones), and an AMI + mitochondrial fission inhibitor group (the other hopeful ones).
After putting these rats through the wringer with all sorts of staining, microscopy, and flow cytometry – because who doesn’t love a good colorful stain and a bit of cell counting – the researchers found that, surprise, surprise, AMI rats showed more heart damage, more cell death, and their mitochondria were splitting up more than a Hollywood couple.
But fear not, for rhein swooped in like a botanical superhero, reducing heart damage, cell death, and keeping those mitochondria together like a determined marriage counselor. It even boosted mitophagy, which is like a cellular KonMari method, making sure only the spark-joy mitochondria get to stay. And, as if by magic (or, you know, science), rhein’s effects were pretty much on par with the mitochondrial fission inhibitor, Mdivi-1.
And because no modern tale is complete without a little in vitro action, the researchers confirmed all this with H9c2 cells in a petri dish, because why test on a rat what you can test on a cell?
So, there you have it, folks. Rhein might just be the next big thing in the fight against myocardial ischemic injury, working its magic through the Drp1/Pink1/Parkin pathway, which is definitely not the name of an indie band… yet.
