Membrane type 1 matrix metalloproteinase regulates anaplastic thyroid carcinoma cell growth and invasion into the collagen matrix. | LitMetric

AI Article Synopsis

Article Abstract

Anaplastic thyroid carcinoma (ATC) is one of the most aggressive cancer types; however, the molecular mechanism contributing to the aggressive characteristics remain unclear. Membrane type 1 matrix metalloproteinase (MT1-MMP) plays an important role in cancer invasion and has been associated with a poor prognosis in various malignant neoplasms. In this study, we investigated the relationship between MT1-MMP expression and the proliferation and invasion of ATC cells, along with the association with clinicopathologic factors in patients with ATC. Suppression of MT1-MMP reduced the proliferation and invasion of ATC cells, and suppressed ERK activity, indicating a role in cancer cell proliferation in collagen matrix culture conditions. The expression of MT1-MMP was detected in 29 of 34 (85.3%) surgical specimens from ATC patients. In addition, the expression of MT1-MMP in the tumor lesion was higher than that of normal and stromal tissues. Collectively, these results suggest that elevated MT1-MMP expression plays a role in the pathogenesis of ATC, which may promote its aggressive characteristics such as proliferation and invasion, highlighting a potential new therapeutic target.
