JMJD1C (Jumonji Domain Containing 1C), a member of the lysine demethylase 3 (KDM3) family, is universally required for the survival of several types of acute myeloid leukemia (AML) cells with different genetic mutations, representing a therapeutic opportunity with broad application. Yet how JMJD1C regulates the leukemic programs of various AML cells is largely unexplored. Here we show that JMJD1C interacts with the master hematopoietic transcription factor RUNX1, which thereby recruits JMJD1C to the genome to facilitate a RUNX1-driven transcriptional program that supports leukemic cell survival. The underlying mechanism hinges on the long N-terminal disordered region of JMJD1C, which harbors two inseparable abilities: condensate formation and direct interaction with RUNX1. This dual capability of JMJD1C may influence enhancer-promoter contacts crucial for the expression of key leukemic genes regulated by RUNX1. Our findings demonstrate a previously unappreciated role for the non-catalytic function of JMJD1C in transcriptional regulation, underlying a mechanism shared by different types of leukemias.

Objective:To compare the health knowledge of newly admitted patients with recurrent hypertensive stroke around 10 years, and analyze the influencing factors of health knowledge of patients.Methods:From September 2008 to December 2009 and from September 2018 to December 2019, convenience sampling was used to select newly admitted patients with recurrent hypertensive stroke from 3 ClassⅢ Grade A hospitals in Guangzhou as the research objects, and the Stroke Knowledge Questionnaire (SKQ) was used for investigation. In the two stages around 10 years, 120 and 130 questionnaires were distributed, and 109 and 116 valid questionnaires were returned with the valid response rates of 90.83% and 89.23%, respectively.Results:The education level, per capita monthly income of the family, family history of stroke, diabetes mellitus and hyperlipidemia, and smoking of the patients before and after 10 years were statistically significant ( P<0.05) . After 10 years, SKQ total scores, dimension scores in exercise, medication, stroke risk factors, stroke auras, and stroke management of patients were higher than those of 10 years ago, and dimension scores low-salt diet and smoking were lower than 10 years ago, and the differences were statistically significant ( P<0.05) . Conclusions:The level of health knowledge of newly admitted patients with recurrent hypertensive stroke is higher than that of 10 years ago, but education on low-salt diet and smoking cessation knowledge should be further strengthened.
