Redistribution of DNA loop domains in human lymphocytes under blast transformation with interleukin 2 [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2016
At higher order levels chromatin fibers in interphase nuclei are organized into loop domains. Gene regulatory elements (promoters and enhancers) are often located near the sites of loop attachments.

Deubiquitinase USP38 Stabilizes PLK1 Expression to Boost DNA Damage Repair in Ovarian Cancer

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Ovarian cancer (OC) is one of the most prevalent and severe gynecological malignant tumors. DNA damage repair (DDR) is essential in maintaining genome stability. This study aims to investigate the effects and mechanisms of USP38 and PLK1 on DNA damage repair and malignant behavior in OC cells.
