Abstract

is a tumor suppressor in follicular lymphoma that controls mTORC1 activity and it is inactivated by chromosomal deletions or epigenetically silenced by mutant EZH2. Pharmacological inhibition of EZH2 promotes re-expression and it restores its tumor suppressive activity, suggesting the possibility to epigenetically control mTORC1 activity.

摘要

是滤泡性淋巴瘤中的一种肿瘤抑制因子,可控制mTORC1活性,它通过染色体缺失而失活,或因突变的EZH2而发生表观遗传沉默。对EZH2的药理学抑制促进其重新表达,并恢复其肿瘤抑制活性,这表明表观遗传控制mTORC1活性具有可能性。
