[3AS-03]【J】Retroelements: Friends or Foes?

Fri. Nov 29, 2024 9:00 AM - 11:15 AM JST
Fri. Nov 29, 2024 12:00 AM - 2:15 AM UTC
Room 3(Fukuoka International Congress Center, 4F 401+402+403)
Organizer: So Nakagawa (Tokai University), Hirosuke Shiura (University of Yamanashi)
Retroelements (REs) are retrotranscribed from RNA to DNA and inserted into genomes, some of which are derived from LINEs and viruses. REs occupy a large portion of the genomes of various organisms. These are usually repressed by epigenetic mechanisms and have been considered as "junk" or even "garbage". However, recent studies have revealed that REs act as "foes" involved in various diseases, and at the same time, they also function as "friends" that play important roles in the development and physiological functions. In this symposium, we would like to report and discuss various aspects of REs.
