1.ATM, DNA-PKcs and ATR: shaping development through the regulation of the DNA damage responses | Demis Menolfi,Shan Zha


ATM, DNA-PKcs and ATR are three PI3-kinase-related protein kinases located at the apex of the DNA damage response (DDR) complex to maintain genomic stability, which is crucial for normal development, healthy aging and prevention of cancer. In this review, Demis Menolfi and Shan Zha discuss how their activation mechanism and how their deficiency leads to specific physiological and pathophysiological consequences, providing essential insight into the structural functions of these proteins beyond their kinase activity, their interaction with co-factors and the developmental and physiological implications.

2.Ubiquitin and the DNA double-strand break repair pathway | Somaira Nowsheen, Min Deng, Zhenkun Lou


Ubiquitin is important in DNA damage repaired. In this review, Zhenkun Lou and colleagues describe how ubiquitination happen and its regulations on various cellular functions, especially on the DNA double-strand break repair. This would help us understanding more on the central roles of ubiquitination in DNA damage response.

3.Crosstalk between signaling pathways and DNA damage response | Kangjunjie Wang, Long Li, Yuxue Zhang, Daming Gao


DNA damage response (DDR) is a complicated progress that involved with various growth signaling pathways. In this review, Daming Gao and colleagues systematically introduce five signaling pathways and their interactions with DDR. This would expand our knowledge of growth signaling networks and help us to design more efficient therapies to related diseases.

4.Maintaining genomic stability in pluripotent stem cells | Ping Zheng


Comparing with differentiated cells, pluripotent stem cells (PSCs) are found to be better in maintaining genomic stability. In this review, ping Zheng summarizes how PSCs deal with DNA replication-associated stress, and repair DNA damages. The knowledge obtained from PSCs could provide clues for disease therapy.
