Predominance of core histones in formation of DNA--protein crosslinks in gamma-irradiated chromatin.

Mee, L K; Adelstein, S J

Chromatin and a subunit of chromatin containing a complex of DNA and the core histones--H2A, H2B, H3, and H4--have been prepared from cultured Chinese hamster cells. Comparison of the formation of radiation-induced DNA--protein crosslinks in whole chromatin with that in the DNA--core histone complex...

On Microvascular Inflammation and Intestinal Leakage in Radiation Enteropathy

Röme, Andrada

Gastrointestinal tract damage is an insidious feature in patients undergoing radiotherapy. Microvascular inflammation, including leukocyte and platelet recruitment as well as epithelial barrier dysfunction, are considered to constitute key components in the pathophysiology of radiation-induced enter...

Molecular markers of ionizing radiation-induced gene mutations in mammalian cells.

Yu, Y; Hsie, A W; Xu, Z; Porter, R C; Sun, J; Meltz, M L; Schwartz, J L

We have isolated independent Chinese hamster ovary (CHO) cell mutants at the hypoxanthine guanine phosphoribosyltransferase (hprt) locus from untreated, 60Co gamma-ray-exposed, and 212Bi alpha-exposed cells and identified the molecular changes underlying the mutation determined by multiplex polymera...

Cell Cycle Kinetics and Radiation-Induced Chromosomal Aberrations Studied with C14 and H3 Labels

Dewey, W. C.; Sedita, B. A.; Humphrey, R. M.

Chinese hamster cells in vitro were double labeled with C14TdR and H3TdR. At the time of irradiation with Co60 gamma rays (600 rad), the cells in the G2 phase were labeled only with C14, whereas cells in the late and middle S phases were labeled with both C14 and H3. The cells in early S phase were ...
