Objective: SET8 is a member of the SET domain-containing family and the only known lysine methyltransferase (KMT) that monomethylates lysine 20 of histone H4 (H4K20me1). SET8 has been implicated in many essential cellular processes, including cell cycle regulation, DNA replication, DNA damage response, and carcinogenesis. There is no conclusive evidence, however, regarding the effect of SET8 on radiotherapy.

Methods: Plasma samples harvested from mice at different time points after carbon-ion or X-ray irradiation were analyzed using meso-scale discovery (MSD), a high-throughput and sensitive electrochemiluminescence measurement technique. Dose estimation equations were set up using multiple linear regression analysis.
There is still a need for better protection against or mitigation of the effects of ionizing radiation following conventional radiotherapy or accidental exposure. The objective of our current study was to investigate the possible roles of matrix metalloproteinase inhibitor, ilomastat, in the protection of mice from total body radiation (TBI), and the underlying protective mechanisms. Ilomastat treatment increased the survival of mice after TBI.

Therefore, it is necessary to develop a novel platform for the propagation of these types of viruses.
Methods: A platform for culturing human airway epithelia in a three-dimensional (3D) pattern using Matrigel as scaffold was developed.
Objective: Adipose tissue distributes widely in human body. The irradiation response of the adipose cells in vivo remains to be investigated. In this study we investigated irradiation response of adipose-derived stem cells (ASCs) under three-dimensional culture condition.

Some of these compounds exhibited strong antiproliferative activities in the submicromolar range. N-Methyl-5,6,7-trimethoxylindoles 21 and 31 displayed the highest antiproliferative activities, with IC50 values ranging from 22 to 125 nM in four human cancer cell lines and activated human umbilical vein endothelial cells (HUVECs).
