Gene Information

human ... ARX(170302)

General description

Aristaless-related homeobox protein (ARX) is a transcription factor that plays an important role in the development of the brain, testis, and pancreas. The gene targets and nuclear associations of ARX are less clear, although it has been demonstrated that ARX interacts with the Pax4 promoter. However, over fifty ARX mutations have been identified and the resultant phenotypes have been well studied. ARX mutations are X-linked and lead to various syndromes including X-linked West syndrome; X-linked myoclonic epilepsy; Partington syndrome; and X-linked mental retardation.

Immunogen

GST-tagged recombinant protein corresponding to human ARX.

Application

Detect ARX using this Anti-ARX Antibody, clone 11F6.2 validated for use in Western Blotting, IHC(P).

Diagnostic cytopathology, 48(4), 308-315 (2019-12-18)
The transcription factors ARX and PDX1, and alternative lengthening of telomeres (ALT) were recently described as prognostic markers for resected non-functional pancreatic neuroendocrine tumors (PanNETs). ALT positive tumors with ARX expression relapse most often. Currently, tumor size is the only

Insulin-producing pancreatic neuroendocrine tumors (PanNETs)/insulinomas are generally considered to be indolent tumors with an excellent prognosis after complete resection. However, some insulinomas have a poor prognosis due to relapses and metastatic disease. Recently, studies in non-functional PanNETs indicated that behavior

Recent studies have found aristaless-related homeobox gene (ARX)/pancreatic and duodenal homeobox 1 (PDX1), alpha-thalassemia/mental retardation X-linked (ATRX)/death domain-associated protein (DAXX) and alternative lengthening of telomeres (ALT) to be promising prognostic biomarkers for non-functional pancreatic neuroendocrine tumours (NF-PanNETs). However, they have
