Research over the last decade recognized the importance of novel molecular pathways in
pathogenesis of intracranial meningiomas. In this review, we focus on human brain tumours …

Meningiomas, tumors that originate from meningothelial cells, account for approximately
30% of all new diagnoses of central nervous system neoplasms. According to the 2016 …

Background The incidence of 2 distinct tumor types occupying the same anatomic location is
rarely observed and may be accounted for by 2 separate mechanisms: tumor-to-tumor …

The HLA-G and HLA-E molecules, Ki67, progesterone (PR), estrogen (ER) and androgen
receptors (AR), p53, COX-2, and HER2 were studied to assess whether the biological …

Objective We conducted this study with the aim of predicting the biological behavior of
meningiomas, and determining the benefits of associating histological subtype and grade …

Background p53 is a tumor suppressor and key regulator of glycolysis in cancer cells,
however highly mutated in tumors. In ovarian cancer, studies concerning p53 mutations …

ABSTRACT Ki-67/MIB-1 is the most widely used immumohistochemical marker to measure
cell proliferation in recent years, and its high expression is significantly related to high …

Background/Aim. Tumor suppressor gene AXIN1 is an inhibitor of Wnt signaling pathway. It
down-regulates the pathway's main signaling effector molecule, beta-catenin, in an AXIN …

Purpose Intracranial collision tumor is a rare entity that represents the coexistence of two
histopathological different tumor types in the same area without histological admixture or an …

The aim of the present study was to identify TP53 exon 4 mutations in patients with
meningioma and to investigate their potential association with specific tumor pathology …
