A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer

The FEBS Journal, EarlyView.
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular

Hydrogel Embedding of Mesenchymal Stem Cells Supports Extracellular Vesicle Production

Biotechnology and Bioengineering, Volume 123, Issue 4, Page 939-949, April 2026.
This study investigates the effects of 3D culture conditions on extracellular vesicle (EV) production by mesenchymal stem cells (MSCs) in a gelatin‐based hydrogel matrix (GelMA). The EVs from both conditions were found to have similar morphological, molecular, and functional properties, but 3D cultures produced more total EVs per volume.

A minimalist chemical model of matrix metalloproteinases- Can small peptides mimic the more rigid metal binding sites of proteins? [PDF]

, 2013
In order to develop a minimalist chemical model of matrix metalloproteinases (MMPs), we synthesized a pentadecapeptide (Ac-KAHEFGHSLGLDHSK-NH2) corresponding to the catalytic zinc(II) binding site of human MMP-13.

Epigenetic mechanisms and therapeutic innovations in chronic pain‐associated neuropsychiatric co‐morbidities

British Journal of Pharmacology, Volume 183, Issue 7, Page 1313-1340, April 2026.
Abstract Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2‐3‐fold increase in neuropsychiatric co‐morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ...

Field-effect transistors assembled from functionalized carbon nanotubes

, 2006
We have fabricated field effect transistors from carbon nanotubes using a novel selective placement scheme. We use carbon nanotubes that are covalently bound to molecules containing hydroxamic acid functionality.
