Abstract
Accidental radiation exposure is a threat to human health that necessitates
effective clinical diagnosis. Suitable biomarkers are urgently needed for early
assessment of exposure dose. Existing technologies being used to assess the
extent of radiation have notable limitations. As a radiation biomarker, miRNA
has the advantages of simple detection and high throughput. In this study, we
screened for miRNAs with dose and time dependent responses in peripheral blood
leukocytes via miRNA sequencing in establishing the animal model of acute
radiation injury. Four radiation-sensitive and stably expressed miRNAs were
selected out in the 24 h group of leukocyte miRNAs: mmu-miR-130b-5p,
mmu-miR-148b-5p, mmu-miR-184-3p, mmu-miR-26a-2-3p, and five were screened in the
48 h group of leukocyte miRNAs: mmu-miR-130b-5p, mmu-miR-423-5p, mmu-miR-676-3p,
mmu-miR-150-5p, mmu-miR-342-3p.The correlation curves between their expression
and irradiation dose were plotted. Then, the results were validated by RT-qPCR
in mouse peripheral blood. As a result, mmu-miR-150-5p and mmu-miR-342-3p showed
the highest correlation at 48h after irradiation, and mmu-miR-130b-5p showed
good correlation at both 24 h and 48 h after irradiation. In a conclusion, the
miRNAs that are sensitive to ionizing radiation with dose dependent effects were
selected out, which have the potential of forming a rapid assessment scheme for
acute radiation injury.

Abstract
DNA double-strand break (DSB) repair is critical for the maintenance of genome stability. The current models of the mechanism of DSB repair are based on studies of DNA repair proteins. Long non-coding RNAs (lncRNAs) have recently emerged as new regulatory molecules, with diverse functions in biological processes. In the present study, we found that expression of the ionizing radiation-inducible lncRNA, lnc-RI, was correlate negatively with micronucleus frequencies in human peripheral blood lymphocytes. Knockdown of lnc-RI significantly increased spontaneous DSBs levels, which was confirmed to be associated with the decreased efficiency of homologous recombination (HR) repair of DSBs. The expression of RAD51, a key recombinase in the HR pathway, decreased sharply in lnc-RI-depressed cells. In a further investigation, we demonstrated that miR-193a-3p could bind with both lnc-RI and RAD51 mRNA and depressed the expression of lnc-RI and RAD51 mRNA. Lnc-RI acted as a competitive endogenous RNA (ceRNA) to stabilize RAD51 mRNA via competitive binding with miR-193a-3p and release of its inhibition of RAD51 expression. To our knowledge, this is the first study to demonstrate the role of lnc-RI in regulating HR repair of DSBs. The feedback loop established in the current study suggests that lnc-RI is critical for the maintenance of genomic stability.

Abstract
PURPOSE A minority of patients exhibits severe late normal tissue toxicity after radiotherapy (RT), possibly related to their inherent individual radiation sensitivity. This study aimed to evaluate four different candidate in vitro cellular radiosensitivity assays for prediction of late normal tissue reactions, in a retrospective matched case-control set-up of breast cancer patients. METHODS The study population consists of breast cancer patients expressing severe radiation toxicity (12 cases) and no or minimal reactions (12 controls), with a follow-up for at least 3 years. Late adverse reactions were evaluated by comparing standardized photographs pre- and post-RT resulting in an overall cosmetic score and by clinical examination using the LENT-SOMA scale. Four cellular assays on peripheral blood lymphocytes reported to be associated with normal tissue reactions were performed after in vitro irradiation of patient blood samples to compare case and control radiation responses: radiation-induced CD8+ late apoptosis, residual DNA double-strand breaks, G0 and G2 micronucleus assay. RESULTS A significant difference was observed for all cellular endpoints when matched cases and controls were compared both pairwise and grouped. However, it is important to point out that most case-control pairs showed a substantial overlap in standard deviations, which questions the predictive value of the individual assays. The apoptosis assay performed best, with less apoptosis seen in CD8+ lymphocytes of the cases (average: 14.45%) than in their matched controls (average: 30.64%) for 11 out of 12 patient pairs (p < .01). The number of residual DNA DSB was higher in cases (average: 9.92 foci/cell) compared to their matched control patients (average: 9.17 foci/cell) (p < .01). The average dose response curve of the G0 MN assay for cases lies above the average dose response curve of the controls. Finally, a pairwise comparison of the G2 MN results showed a higher MN yield for cases (average: 351 MN/1000BN) compared to controls (average: 219 MN/1000BN) in 9 out of 10 pairs (p < .01). CONCLUSION This matched case-control study in breast cancer patients, using different endpoints for in vitro cellular radiosensitivity related to DNA repair and apoptosis, suggests that patients' intrinsic radiosensitivity is involved in the development of late normal tissue reactions after RT. Larger prospective studies are warranted to validate the retrospective findings and to use in vitro cellular assays in the future to predict late normal tissue radiosensitivity and discriminate individuals with marked RT responses.
