Replication protein A (RPA), essential for DNA replication, repair and DNA damage signalling, possesses six ssDNA-binding domains (DBDs), including DBD-F on the N-terminus of the largest subunit, RPA70. This domain functions as a binding site for p53 and other DNA damage and repair proteins that contain amphipathic alpha helical domains. Here, we demonstrate direct binding of both ssDNA and the...

BACKGROUND Liver T-cells respond to the inflammatory insult generated during organ procurement and contribute to the injury following reperfusion. The mode of liver donation alters various metabolic and inflammatory pathways but the way it affects intrahepatic T-cells is still unclear. METHODS We investigated the modifications occurring in the proportion and function of T-cells during liver p...

Use of marginal liver grafts, especially those from donors after circulatory death (DCD), has been considered as a solution to organ shortage. Inferior outcomes have been attributed to donor warm ischaemic damage in these DCD organs. Here we sought to profile the metabolic mechanisms underpinning donor warm ischaemia. Non-targeted Fourier transform ion cyclotron resonance (FT-ICR) mass spectrom...

The yeast Spt10p activator is a putative histone acetyltransferase (HAT) possessing a sequence-specific DNA-binding domain (DBD) which binds to the upstream activation sequences (UAS elements) in the histone gene promoters. Spt10p binds to a pair of histone UAS elements with extreme positive cooperativity. The molecular basis of this cooperativity was addressed. Spt10p (640 residues) is an elon...

Diabetic bladder dysfunction (DBD) is common and affects 80% of diabetic patients. However, the molecular mechanisms underlying DBD remain elusive because of a lack of appropriate animal models. We demonstrate DBD in a mouse model that harbors hepatic-specific insulin receptor substrate 1 and 2 deletions (double knockout [DKO]), which develops type 2 diabetes. Bladders of DKO animals exhibited ...

Rationale: Signal transducer and activator of transcription-3 (STAT3) plays a pivotal role in cancer biology. Many small-molecule inhibitors that target STAT3 have been developed as potential anticancer drugs. While designing small-molecule inhibitors that target the SH2 domain of STAT3 remains the leading focus for drug discovery, there has been a growing interest in targeting the DNA-binding ...

In today's world, the production of hospital wastes and their adverse effects such as infectious outbreaks and resistance to treatment is an important issue. Therefore, it's vital to find a new and efficient method to manage such wastes. In this study, the ability of dielectric barrier discharge (DBD) plasma to deactivate Pseudomonas aeruginosa and Staphylococcus aureus bacter...

Introduction Perigraft fluid collection (PFC) is a common complication after kidney transplant. Its etiology is not clear and not all the causes have been identified. The influence of the type of donor has never been evaluated. Our aim was to compare the incidence, severity and management of PFC in recipients of grafts from uncontrolled donors after circulatory death (DCD) with normothermic ext...

Members of the nuclear receptor superfamily differentiate in terms of specificity for DNA recognition and binding, oligomeric state, and ligand binding. The wide range of specificities are impressive given the high degree of sequence conservation in the DNA binding domain (DBD) and moderate sequence conservation with high structural similarity within the ligand binding domains (LBDs). Determini...

PURPOSE Herpes keratitis (HK) is the leading cause of cornea-derived and infection-associated blindness in the developed world. Despite the availability of effective antivirals, some patients develop refractory disease, drug-resistant infection, and topical toxicity. A nonpharmaceutical treatment modality may offer a unique advantage in the management of such cases. This study investigated the ...
