Immunohistochemical Determination of the Matrix Metalloproteinase-2 and -7 Expression in Transmissible Venereal Tumor in Dogs

Expression of Matrix Metalloproteinase-2 and -9 in Meningioma

Background: Meningioma is one of the most common tumors of the central nervous system. It was shown that meningioma had up-regulated expression of Matrix Metalloproteinases (MMPs) that involved in cell growth, angiogenesis and metastasis.  Objectives: The aim of the study was the assessment of serum MMP-2 and -9 levels in patients with different grades of meningioma.  Materials & Me...

Disseminated transmissible venereal tumor in a dog.

Transmissible venereal tumor (TVT) is a well-documented transplantable tumor in dogs, with no breed or sex predilection and a low metastatic rate. In this report, a 2-year-old intact female Mastiff that had numerous, rapidly growing masses throughout the subcutis mainly at the dorsal body plane, the caudal half of the ventral abdomen, and around the vulva was euthanized due to poor prognosis. N...

Matrix Metalloproteinase-2 and -7 Expression in Colorectal Cancer

PURPOSE Matrix metalloproteinase-2 (MMP-2) and MMP-7 have been implicated in tumor growth and metastasis. This study aimed to investigate the expressions of MMP-2 and -7 in colorectal cancer and to evaluate their values as prognostic markers. METHODS Immunohistochemical staining for MMP-2 and -7 was done in 144 resected colorectal cancer specimens. Clinicopathological data and survival result...
