IUCrJ, 2018 Cyclobutane pyrimidine dimer (CPD) photolyases harness the energy of blue light to repair UV-induced DNA CPDs. Upon binding, CPD photolyases cause the photodamage to flip out of the duplex DNA and into the catalytic site of the enzyme.

Veterinary Ophthalmology, EarlyView.ABSTRACT Objective To investigate the antimicrobial effect of 275 nm wavelength ultraviolet C (UV‐C) light on M. bovis using an affordable, broadly available modified handheld device and to determine if photoreactivation plays a role in bacterial resistance to UV‐C. Methods UV‐C therapy (UVCT) was evaluated in vitro using triplicates of 3 M.

Nature Communications, 2017 UV-induced mutagenic cyclobutane pyrimidine dimers on nucleosomal DNA are sensed by the damage recognition factors DDB2 and XPC via an unknown mechanism. Here, the authors show that the histone methyltransferase ASH1L regulates the DDB2 to XPC handoff by

Veterinary Ophthalmology, EarlyView.ABSTRACT Objective To assess if an inexpensive, commercially available ultraviolet C (UV‐C) light device with a peak emission of 275 nm can inhibit equine keratomycosis‐associated pathogens located at different corneal depths in an ex vivo model. Methods A controlled, randomized experimental design.
