When tissues are injured, enzymes that cut other proteins can either help repair the damage or make it worse. Meprins are one family of these protein-cutting enzymes, called metalloproteases because they need a metal ion to work.

What they work on

  1. Determine how single nucleotide polymorphisms (SNPs) in the meprin beta gene change the enzyme's interactions with its substrates and with sheddases, the enzymes that release it from cells.
  2. Determine how meprin cutting of substrates such as inflammatory signals, cell-junction proteins and structural proteins changes signaling during hypoxia, inflammation and turnover of the tissue's structural scaffold, using molecular biology, proteomics and meprin knockout mice.
  3. Evaluate meprins and their cleavage products as biomarkers for diagnostic tools to detect diabetic kidney injury and Alzheimer's disease early.

More about the research

They are linked to inflammation and scarring diseases. These include kidney disease, inflammatory bowel disease, lung fibrosis, Alzheimer's disease and cancer. Meprins are most abundant in the kidney and small intestine. They are also found in immune cells, skin, blood vessel lining and cancer cells. This research asks how meprins drive tissue injury and whether they could serve as early warning signs of disease.

Why it matters

Meprins are implicated in chronic kidney injury caused by diabetes and in Alzheimer's disease. Knowing how meprin gene variants and meprin activity drive tissue damage could point to new treatment targets. Meprins and the protein fragments they produce could become biomarkers for diagnostic tests that catch diabetic kidney injury or Alzheimer's disease early. This would support more personalized care for patients with genetic risk.
