Loss of SPINT2 expression frequently occurs in glioma, leading to increased growth and invasion via MMP2

Os gliomas de alto grau representam um dos mais agressivos tipos tumorais, quer em adultos, quer em crianças. As proteases de serina e as metaloproteases (MMP) desempenham papéis-chave nos mecanismos de migração e invasão celular. A proteína SPINT2, é um importante inibidor de proteases de serina que influencia também a via a sinalização do recetor MET. O SPINT2 está frequentemente desregulado em vários tumores, principalmente através da hipermetilação do seu promotor.

Hypermethylation of the TERT promoter predicts biochemical recurrence in prostate cancer: a retrospective study

Prostate cancer (PC) is the most common cancer in the male population with a high prevalence from 60 years old. Despite the high prevalence, mortality rates are variable and reflect the heterogeneous nature (clinical and biological) of this disease. Recent studies have shown that most patients with low-risk disease do not need treatment. However, in this apparently homogeneous group, there are patients who have aggressive disease - and benefit from therapy.
