Proc Natl Acad Sci U S A

November 2024

Division of Hematology and Medical Oncology, Mays Cancer Center, University of Texas Health Science Center San Antonio, San Antonio, TX 78229.

Article Synopsis
  • - RNA can be chemically modified through methylation, particularly at the N6-methyladenosine (mA) site on mRNA, which is regulated by the methyltransferase complex and removed by demethylases FTO and ALKBH5.
  • - The outcome of mA-marked mRNA can either lead to its degradation or stabilization/translation, influenced largely by its interaction with specific proteins known as YTH domain-containing proteins.
  • - New insights show that factors like metabolism and posttranslational modifications can affect the functioning and location of FTO and ALKBH5, indicating that mA methylation is a dynamic process that warrants further exploration in cancer and other health conditions.

ENL mutation and AML: a new model that reveals oncogenic condensate's function in leukemogenesis.

Mol Oncol

September 2024

Department of Biochemistry and Molecular Biology, University of Texas Health Science Center at Houston, McGovern Medical School, TX, USA.

Article Synopsis
  • Proper gene expression regulation is crucial for organismal development and maintaining homeostasis, with some proteins forming condensates that can influence gene expression; disruptions in these condensates are linked to cancers like Ewing sarcoma and AML.
  • Recent research by Liu et al. indicates that mutations in the ENL protein's YEATS domain act as oncogenic drivers in acute myeloid leukemia (AML) by forming condensates at important leukemic gene regions.
  • The study shows that disrupting these condensates diminishes oncogenic functions, and using small-molecule inhibitors can effectively reduce AML development by targeting these mutant ENL condensates.
