RNA helicase DHX9 is essential for genome stability by resolving aberrant R-loops. However, its regulatory mechanisms remain unclear. Here we show that SUMOylation at lysine 120 (K120) is crucial for DHX9 function.

Aberrant DNA/RNA hybrids (R-loops) formed during transcription and replication disturbances pose threats to genome stability. DHX9 is an RNA helicase involved in R-loop resolution, but how DHX9 is regulated in response to genotoxic stress remains unclear. Here we report that DHX9 is phosphorylated at S321 and S688, with S321 phosphorylation primarily induced by ATR after DNA damage.

Aim: This paper is a report of a trial to examine the effectiveness of individualized self-care education programmes in older adults with moderate-to-severe asthma.

Background: Asthma is a common chronic disease in adults and a major cause of frequent work absences, emergency room visits, and hospitalization. The results of studies of self-care education programmes have been largely supportive and suggest that they have positive outcomes for people with asthma.
