... Cav3.2 transgenic mice from Mutant Mouse Resource and Research Centers (MMRRC: 009979-MU; strain name: B6.129-Cacna1htm1Kcam/Mmmh) were maintained in the C57Bl/6J background. For subsequent ABR recordings, Cav3.2+/+ controls, heterozygous Cav3.2+/- and homozygous {} mutant Cav3.2-/- mice (55 animals in total) were used from both age-matched genders with the following characteristics: Males: Cav3.2+/+: n = 11 (♂), weight 32.82 ± 0.58 g; Cav3.2+/-: n = 7 (♂), weight 33.11 ± 0.81 g; Cav3.2-/-: n = 9 (♂), weight 29.09 ± 0.75 g. Females: Cav3.2+/+: n = 12 (♀), weight 24.09 ± 0.41 g; Cav3.2+/-: n = 8 (♀), weight 23.50 ± 0.41 g; Cav3.2-/-: n = 8 (♀), weight 22.10 ± 0.43 g. For recording of monaural bioelectrical auditory potentials, subdermal stainless steel electrodes were inserted at the vertex, axial the pinnae (+ electrode) and ventrolateral of the right pinna (- electrode). The ground electrode was positioned at the hip of the animal. To verify proper electrode positioning / conductivity, impedance measurements of all electrodes (< 5 kΩ) were carried. Note that some recordings also include 2-channel, i.e. binaural measurements. ABR data acquisition was carried out at a sampling rate of 24.4 kHz and signals were bandpass filtered (high pass 300 Hz, low pass 5 kHz) using a 6-pole Butterworth filter. The individual ABR data acquisition time was 25 ms starting with a 5 ms baseline period prior to the individual acoustic stimulus onset (pre ABR baseline) and exceeding the 10 ms ABR section by another 10 ms baseline (post ABR baseline). Two types of acoustic stimuli were applied for ABR recordings in Cav2.3+/+, Cav2.3+/- and Cav2.3-/- mice using the SigGenRZ software (TDT, USA) and applied via the TDT BioSigRZ platform. The first stimulus entity was a click of 100 µs duration, with alternating polarity (switching between condensation and rarefaction). The second stimulus entity was a 4.5 ms tone burst (transient sinusoidal plus) of alternating polarity with Hann envelope rise and fall times of 1.5 ms duration each. (Note that the file header description states an overall duration of 5 ms). The frequency range covers 1 - 42 kHz in 6 kHz steps. All acoustic stimuli were applied 300 times at a rate of 20 Hz for averaging. Sound pressure levels (SPLs) were increased in 5 dB steps for clicks and 10 dB steps for tone bursts, starting from 0 dB up to 90 dB (increasing SPL mode). For tone burst experiments, low SPLs were sometimes excluded to reduce duration of ABR animal experimental. As the raw data file format (arf.) of the TDT system is not freely accessible, data were exported as txt.-files. Header descriptions for both click and tone burst related ABR txt.-files are also attached.

... Cav2.3+/- embryos (kindly provided by Richard j. Miller, The University of Chicago, Chicago, IL) were re-derived with C57BL/6J mice and maintained with random intra-strain mating obtaining all genotypes (Mouse Genome Informatics; MGI Ref. ID J: 66144). For subsequent ABR recordings, Cav2.3+/+ controls, heterozygous Cav2.3+/- and homozygous {} mutant Cav2.3-/- mice (58 animals in total, aged 141.29 ± 0.39 days (~ 20 wks)) were used from both age-matched genders with the following characteristics: Males: Cav2.3+/+: n = 9 (♂), weight 32.72 ± 1.80 g; Cav2.3+/-: n = 9 (♂), weight 31.64 ± 1.12 g; Cav2.3-/-: n = 10 (♂), weight 31.10 ± 0.89 g. Females: Cav2.3+/+: n = 9 (♀), weight 25.41 ± 0.57 g; Cav2.3+/-: n = 10 (♀), weight 25.42 ± 1.36 g; Cav2.3-/-: n = 11 (♀), weight 27.00 ± 0.43 g.

... Whole-genome-sequencing (WGS) of human tumours has revealed distinct mutation patterns that hint at the causative origins of cancer. We examined mutational signatures in 324 WGS of human induced pluripotent stem cells (iPSCs) following exposure to known or suspected environmental carcinogens. 79 agents were tested at concentrations that produced measurable cytotoxicity; 41 yielded characteristic substitution mutational signatures. Some exhibited similarity with signatures found in human tumours. Additionally, 6 agents produced double-substitution signatures and 8 produced indel signatures. Investigating mutation asymmetries across genome topography revealed fully functional mismatch and transcription-coupled repair pathways in iPSCs. Primary adducts induced by environmental carcinogens can be resolved by disparate repair/replicative pathways, resulting in an assortment of signature outcomes even for a single mutagen. This compendium of experimentally-induced mutational signatures permits further exploration of roles of environmental agents in cancer aetiology, and underscores how human stem cell DNA is directly vulnerable to environmental agents.
