Is PTPRZ1 a tyrosine phosphatase?

PTPRZ1 was highly expressed in human neuroendocrine tumor tissues and PTPRZ1 is an oncogenic tyrosine phosphatase in small-cell lung carcinoma. Receptor-type Protein tyrosine phosphatase beta regulates met phosphorylation and function in head and neck squamous cell carcinoma.

Is ptprz1-met fusion associated with glioblastoma malignant growth?

High PTPRZ1 expression is associated with glioblastoma. Molecular crosstalk between tumour-associated macrophages and glioma stem cells through PTN-PTPRZ1 paracrine signalling supports glioblastoma malignant growth. Authors characterized exosomes from GBM cells harbouring and not harbouring PTPRZ1-MET fusion (ZM fusion).

How does mir-1261 regulate ptprz1-etv1 fusion in gliomas?

A novel PTPRZ1-ETV1 fusion in gliomas. Expression of circ-PTPRZ1/PAK1 is regulated by miR-1261, which affects the proliferation, apoptosis, and invasion of glioma cells.

Is CDK5 activated by PTN pro-angiogenic?

Expression of circ-PTPRZ1/PAK1 is regulated by miR-1261, which affects the proliferation, apoptosis, and invasion of glioma cells. The data reveal that CDK5 is activated by PTN, in an RPTPbeta-zeta-dependent manner, regulates PTN-induced cell migration and is an attractive target for the inhibition of PTN pro-angiogenic properties.
