TIMP-4 and CD63: new prognostic biomarkers in human astrocytomas.Rorive S1, Lopez XM, Maris C, Trepant AL, Sauvage S, Sadeghi N, Roland I, Decaestecker C, Salmon I.
Based
on the molecular profiling of astrocytomas, we previously identified a
series of genes involved in astrocytoma invasion. Of these, tissue
inhibitor of metalloproteinase-4 (TIMP-4) was found to be overexpressed
in pilocytic astrocytomas relative to diffuse astrocytomas of any
histological grade. Although some data suggest that TIMP-4 may be an
anti-tumoral actor in astrocytomas, recent findings challenge this
concept. The present study aims to investigate the diagnostic and
prognostic values of TIMP-4 and its putative partner CD63 in human
astrocytomas. Tissue microarray and image analysis were first carried
out to quantitatively analyze the immunohistochemical expression of
these proteins in 471 gliomas including 354 astrocytomas. Pathological
semi-quantitative scores of both markers' expression were then
established and correlated to astrocytoma diagnosis and patient
prognosis. TIMP-4 and CD63 expressions were both overexpressed in
astrocytomas compared with oligodendrogliomas (P<0 .001="" a="" addition="" adverse="" and="" as="" associated="" association="" astrocytic="" astrocytoma="" astrocytomas="" cd63="" cells.="" co-expression="" compared="" conclusion="" contribution="" diffuse="" evidence="" factors="" first="" glioblastomas.="" glioblastomas="" gliomas.="" grade="" high="" highlights="" identified="" identifies="" ii="" in="" independent="" it="" markers="" of="" outcomes="" p="" patients="" phenotype="" pilocytic="" prognostic="" progression="" provides="" scores="" shorter="" survival.="" the="" this="" timp-4="" to="" tumor="" were="" with="" work="">0>
