★ ★ ★ ★ ☆

In areas in which internal controls, neurones, glia and blood vessels were properly stained, the ATRX immunoreactivity of tumour cells was either almost totally absent or completely retained in all cases. There was perfect concordance between the immunohistochemical results and ATRX mutation status, which was known in 19 cases. ATRX loss was ...

The ATRX gene provides instructions for making a protein that plays an essential role in normal development. Although the specific function of the ATRX protein is unknown, studies suggest that it helps regulate the activity (expression) of other genes through a process known as chromatin remodeling.

11/9/2015 · RESULTS: Median age in all patients was 49,3 years. Loss of ATRX expression was detected in 4 out of 23 patient tumors. All ATRX loss patients were primary glioblastomas. Median survival in ATRX mutated gliomas is 237 weeks which was longer than overall survival in gliomas with retained ATRX (88 weeks).

In plants, LHP1 evolved a specific domain for interaction with the plant-specific domain of the putative chromatin remodeler ATRX. Arabidopsis ATRX localizes to specific sites marked by H3K27me3. ATRX participates in deposition of histone variant H3.3 and assists in H3K27me3 deposition by PRC2 at a subset of loci including the flowering time regulator FLC.
