Description

Ionizing radiation is genotoxic to cells. Healthy tissue toxicity in patients and radiation resistance in tumors present common clinical challenges in delivering effective radiation therapies. Radiation response is a complex, polygenic trait with unknown genetic determinants. This study investigated the genetics of natural variation for sensitivity to radiation, among which 92 radiosensitive lines and 62 radioresistant lines were identified. However. variants in known DNA damage and repair genes associated with radiation response were not present among the significant hits, and no variant met the genome-wide significance threshold (p=1.49e⁻⁷), indicating a necessity for a larger sample size.

Comments from curator

Phenotyping data comes from Supp. Table S2 in the Supporting information section.

The radiation source was a commercial Cs¹³⁷ irradiator emitting 662 keV gamma photons, and the irradiator was calibrated using a PTW N31010 ionization chamber. Survival was defined as the ability of males to fly 24 hours post-irradiation, and survival time was expressed in percentage as the mean of two trials.

Important note: We've loaded the raw data, but the data were weirdly reported in Table S2. We realized that we had to double the survival ratio values to make it work (i.e. being able to reproduce not only the mean values, but also the standard deviation and coefficient of variation provided by the authors)...

Note: The authors also report Wolbachia status, but it comes from another study, so we don't report it here (MacKay et al., 2012). They also report temporal phenotypic stability (after 5 months) of 12 highly resistant lines (Supp. Table S5), but given the sparsity of the data, we also don't report it here.
