Listen, folks, we’ve got something really interesting here. We’re talking about proline metabolism, okay? It’s a big deal in cancer, but when it comes to gliomas, the brain tumors, we don’t know much. It’s true. But we’ve got this study, and it’s looking at the worst kind, grade 4 gliomas, right in the brain. Very important work.
We took 20 samples, the best samples. Tumor and normal brain, side by side. We’re not messing around. We checked everything: POX/PRODH, PYCR1/2/3, PEPD, the metalloproteinases, MMP-2, MMP-9, and of course, proline levels. Very comprehensive.
And guess what we found? In normal brains, POX/PRODH is doing fine, but in gliomas, it’s down, way down. PYCR1, PEPD, MMP-2, and MMP-9? They’re up, way up. And proline levels? Through the roof, 358% higher in gliomas. Unbelievable.
So what does this mean? It means we’ve got a new profile for these gliomas. Low POX/PRODH, high PYCR, PEPD, and MMPs. It’s a big deal because it’s all about how these tumors are eating up collagen and getting aggressive. We’ve got to look into this more. It’s huge. We’re talking about the potential for new treatments, new hope. Great stuff.
