MMP2

MTA actively inhibits metalloproteinase too.

MMP-2.

Right.

It's an endogenous enzyme that degrades the collagen matrix in dentin.

By inhibiting MMP-2, MTA preserves the collagen network, keeping the root tough and elastic.

Plus, the sealing ability is driven by its expansion during setting.

And the data here is fascinating.

One of the most striking findings was the increased expression of genes involved in extracellular matrix, ECM, remodeling and collagen production.

Tumor-associated MECs showed elevated levels of multiple collagen genes, matrix metalloproteinases, MMP2, MMP9, MMP11, and MMP14, and ECM-associated proteins such as SPARC and lumican.

At the same time, these cells demonstrated reduced expression of traditional epithelial markers, including KRT5, KRT7, and KRT14.

This combination of changes suggests a transition away from their normal barrier-forming role and toward a more mesenchymal fibroblast-like phenotype that may contribute to tumor progression.

The treatment with folate significantly reduced thermal hyperalgesia, pain, combined with control mice.

Additionally, a reduction in MMP-2 has, has been found after treatment with folate.

MMP-2s are involved in the induction of neuropathic pain.

So a potential mechanism for the counteracting of pain using folate was suggested.

A potential role of vitamin B12 has been proposed.
