Metalloproteases meprin α and meprin β are C- and N-procollagen proteinases important for collagen assembly and tensile strength.

2013

Type I fibrillar collagen is the most abundant protein in the human body, crucial for the formation and strength of bones, skin, and tendon. Proteolytic enzymes are essential for initiation of the assembly of collagen fibrils by cleaving off the propeptides. We report that Mep1a −/− and Mep1b −/− mice revealed lower amounts of mature collagen I compared with WT mice and exhibited significantly reduced collagen deposition in skin, along with markedly decreased tissue tensile strength. While exploring the mechanism of this phenotype, we found that cleavage of full-length human procollagen I heterotrimers by either meprin α or meprin β led to the generation of mature collagen molecules that s…

Abstract 2935: Novel combination of repurposed drugs induces complete cell invasion arrest of glioblastoma in vitro

2019

Abstract Introduction: Glioblastoma multiforme (GBM) is an aggressive and lethal cancer with a poor prognosis even after conventional treatment (surgery, radiation, chemotherapy). Temozolomide (TMZ) is a standard cyotoxic agent used, despite resistance leading to recurrence. Therefore, additional strategies for targeting the tumor environment are needed. We demonstrate a combination of approved drugs (CAD) repurposed to target GBM leads to complete arrest of GBM cell invasion. Each drug in the combination individually targets diverse tumor pathways: 1) invasion via MMP2 (doxycycline); 2) angiogenesis, inflammation, and proliferation via p53-dependent G1 cell-cycle arrest (celecoxib); 3) aut…
