Abstract
Many chromatin remodeling and modifying proteins are involved in the DNA damage response, where they stimulate repair or induce DNA damage signaling. Interestingly, we identified that downregulation of the histone H1 (H1)-interacting protein SET results in increased resistance to a wide variety of DNA damaging agents. We found that this increased resistance does not result from alleviation of an inhibitory effect of SET on DNA repair but, rather, is the consequence of a suppressed apoptotic response to DNA damage. Furthermore, we provide evidence that the histone chaperone SET is responsible for the eviction of H1 from chromatin. Knockdown of H1 in SET-depleted cells resulted in re-sensitization of cells to DNA damage, suggesting that the increased DNA damage resistance in SET-depleted cells is the result of enhanced retention of H1 on chromatin. Finally, clonogenic survival assays showed that SET and p53 act epistatically in the attenuation of DNA damage-induced cell death. Taken together, our data indicate a role for SET in the DNA damage response as a regulator of cell survival following genotoxic stress.This article has an associated First Person interview with the first author of the paper.

Abstract
The effect of caffeine given as pre- and post-treatment in mice exposed to whole-body gamma-irradiation (1.5 Gy 60Co gamma-rays) was studied. The pre-treatment was either acute or chronic. The acute dose (5 mg/kg and 15 mg/kg body weight) was in the form of an injection given intraperitoneally, 30 min before irradiation. The chronic administration was in the form of caffeine solution (4.208 x 10(-3) M and 7.72 x 10(-4) M) contained in the drinking water that mice had had ad libitum access to instead of plain drinking water for 5 weeks prior to radiation exposure. The acute pre-treatment with caffeine reduced the radiation-induced frequency of chromosomal aberrations discernibly, whereas the chronic pre-treatment afforded a much more significant degree of radioprotection. The caffeine post-treatment (5 mg/kg and 15 mg body weight) was given in the form of an intraperitoneal injection to the mice immediately following whole-body gamma-irradiation. It is noted that both post-treatment concentrations of caffeine also significantly reduced the frequency of chromosomal aberrations induced by gamma-rays. These data are briefly discussed in terms of possible mechanistic considerations.

Abstract
A86 Xenopus cells, cloned from a Xenopus line that exhibited a high level of photoreactivation of UV-induced lethal damage, and V79M1 hamster cells, cloned from a hamster line that did not exhibit efficient photoreactivation of such damage, were fused to produce the V79M1 x A86 cell line--a hybrid line in which approximately 84% of the cells contained the entire V79M1 and A86 genomes. Ultraviolet and UV plus photoreactivation fluence-survival relations were then determined and compared for hybrid and parental G1 phase cells in a first attempt to elucidate interactions of the parental genetic potentials for photoreactivation in the hybrid. Specifically, it was anticipated that the combined V79M1 and A86 genomes in the hybrid would produce photoreactivating enzymes sufficient to efficiently photoreactivate UV-induced lethal damage in both A86 and V79M1 DNA and little difference would be observed in the levels of photoreactivation exhibited by V79M1 x A86 and A86 G1 phase cells. To the contrary, the level of photoreactivation observed for the hybrid did not closely approach that observed for the A86 line. To assist in the interpretation of this somewhat unexpected observation, three additional studies were performed: (1) comparison of 'optimal' schemes for photoreactivation of UV-induced lethal damage in the hybrid and parental G1 phase cells, (2) comparison of the effects of some different types of growth medium on photoreactivation of UV-induced lethal damage in hybrid and parental G1 phase cells, and (3) comparison of the levels of photoreactivation of UV-induced chromatid deletions in the V79M1 and A86 chromosomes of G1 phase hybrid cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Clonal subpopulations of different ploidy values and metastatic capacities, isolated from the RIF-1 mouse sarcoma, have been tested for in vitro X-radiation sensitivity, for in vitro sensitivity to adriamycin and for in vitro and in vivo sensitivity to melphalan and CCNU. Following X-radiation, no consistent differences in the survival curve characteristics (Do and n) of diploid, tetraploid and octoploid cells were observed. In addition no relationship between radiation response and metastatic capacity was observed. For drug response, no marked differences were found in the dose response curves of RIF-1 clones treated in vitro with adriamycin. However, a wide variation in the responses of RIF-1 clones to in vitro melphalan treatment was observed which was independent of both ploidy and metastatic capacity. Although the responses of RIF-1 clones to in vitro CCNU treatment were similarly independent of metastatic capacity, a clear relationship between CCNU sensitivity and ploidy was observed. Thus, all diploid RIF-1 clones were markedly more sensitive to CCNU treatment than either tetraploid or octoploid RIF-1 clones. For both melphalan and CCNU treatment the relative sensitivities in vitro correlated with in vivo sensitivities as assayed by clonogenic cell survival.

Abstract
Survival and repair of DNA following ultraviolet (254-nm) radiation have been investigated in ICR 2A, a cultured cell line from haploid embryos of the grassfrog, Rana pipiens. Survival curves from cells recovering in the dark gave mean lethal dose value (Do) in the range 1.5--1.7 Jm-2 for both haploid and diploid cell stocks. The only significant difference observed between haploids and diploids was in the extent of the shoulder at low fluence (Dq), the value for exponentially multiplying diploid cells (3.0 Jm-2) being higher than that found for haploids (1.2 Jm-2). Irradiation of cultures reversibly blocked in the G1 phase of the cell cycle gave survival-curve coefficients indistinguishable between haploids and diploids. Post-irradiation exposure to visible light restored colony-forming capacity and removed chromatographically estimated pyrimidine dimers from DNA at the same rates. After fluences killing 90% of the cells, complete restoration of survival was obtained after 60-min exposure to 500 foot-candles, indicating that in this range lethality is entirely photoreversible and therefore attributable to pyrimidine dimers in DNA. Dimer removal required illumination following ultraviolet exposure, intact cells and physiological temperature, implying that the photoreversal involved DNA photolyase activity. Excision-repair capacity was slight, since no loss of dimers could be detected chromatographically during up to 48 h incubation in the dark and since autoradiographically detected "unscheduled DNA synthesis" was limited to a 2-fold increase saturated at 10 Jm-2. These properties make ICR 2A frog cells useful to explore how DNA-repair pathways influence mutant yield.
