Many of the toxicants in tobacco smoke undergo biotransformation in the lungs of smokers, both to reactive and to detoxified derivatives. Human air-liquid-interface (ALI) airway tissue models have emerged as an advanced in vitro model for evaluating the toxicity of inhaled substances; however, the metabolic potential of these cultures has not been evaluated extensively. In this study, we compared the metabolic activities of an ALI tissue model to the undifferentiated normal human primary bronchial epithelial (NHBE) cells from which it was derived. Read More

Exposure to environmental chemicals has been shown to have an impact on the epigenome. One example is a known human carcinogen 1,3-butadiene which acts primarily by a genotoxic mechanism, but also disrupts the chromatin structure by altering patterns of cytosine DNA methylation and histone modifications. Sex-specific differences in 1,3-butadiene-induced genotoxicity and carcinogenicity are well established; however, it remains unknown whether 1,3-butadiene-associated epigenetic alterations are also sex dependent.

To control a spore-forming human pathogen , we isolated and characterized a novel endolysin, LysPBC2, from a newly isolated phage PBC2. Compared to the narrow host range of phage PBC2, LysPBC2 showed very broad lytic activity against all , , and species tested. In addition to a catalytic domain and a cell wall binding domain, LysPBC2 has a spore binding domain (SBD) partially overlapped with its catalytic domain, which specifically binds to spores but not to vegetative cells of Both immunogold electron microscopy and binding assay indicate that the SBD binds the external region of the spore cortex layer.

In a recent issue of , Kathuria et al [ (2018) , 3039-3055] report that membrane binding of the pore-forming toxin cytolysin (VCC) is facilitated by the presence of cholesterol, and the presence of this sterol within the lipid bilayer is key for the formation of a functional pore. Yet, in the presence of accessory non-lipid components, VCC retains its membrane-binding capability likely through membrane lipid raft structures. In light of their results, the authors provide new insights into the roles of cholesterol and of membrane microstructures in the binding, the oligomeric assembly and the cytolytic pore formation of VCC which all take place following infection by .

Phosphoenolpyruvate carboxykinase (PEPCK1) is ubiquitinated by E3 ubiquitin ligase UBR5, which was thought to be facilitated by the acetylation of Lys70, Lys71 and Lys594 in PEPCK1. Here, we made a series of UBR5 HECT domain truncation variants and, through pull-down assay, showed that the N-terminal lobe of the UBR5 HECT domain is largely responsible for interacting with PEPCK1. We mutated all three lysine residues thought to be acetylated in PEPCK1 but were surprised to observe no loss of binding to UBR5 HECT domain. Read More

The corneal endothelium, which originates from the neural crest via the periocular mesenchyme (PM), is crucial for maintaining corneal transparency. The development of corneal endothelial cells (CECs) from the neural crest is accompanied by the expression of several transcription factors, but the contribution of some of these transcriptional regulators to CEC development is incompletely understood. Here, we focused on activating enhancer-binding protein 2 (TFAP2, AP-2), a neural crest-expressed transcription factor. Read More

Loss-of-function mutations in , a gene exclusively found in higher eukaryotes, cause a characteristic type of cavitating leukoencephalopathy associated with mitochondrial cytochrome oxidase (COX) deficiency. Although the genetic association of APOPT1 pathogenic variants with isolated COX defects is now clear, the biochemical link between APOPT1 function and COX has remained elusive. We investigated the molecular role of APOPT1 using different approaches. Read More

ScFv is emerging as a therapeutic alternative to the full-length monoclonal antibodies due to its small size and low production cost, but its low solubility remains a limiting factor toward wider use. Here, we increased the solubility of an Anti-epidermal growth factor receptor ScFv (Anti-EGFR ScFv) by attaching, a short 12-residue solubility enhancing peptide (SEP) tag at its C terminus. We first estimated the solubility increase by running 500-ns Brownian dynamics (BD) simulations. Read More

A critically ill polytrauma patient is one of the most complex cases to be admitted to the intensive care unit, due to both the primary traumatic complications and the secondary post-traumatic interactions. From a molecular, genetic, and epigenetic point of view, numerous biochemical interactions are responsible for the deterioration of the clinical status of a patient, and increased mortality rates. From a molecular viewpoint, microRNAs are one of the most complex macromolecular systems due to the numerous modular reactions and interactions that they are involved in. Read More

Newborn mice emit signals that promote parenting from mothers and fathers but trigger aggressive responses from virgin males. Although pup-directed attacks by males require vomeronasal function, the specific infant cues that elicit this behavior are unknown. We developed a behavioral paradigm based on reconstituted pup cues and showed that discrete infant morphological features combined with salivary chemosignals elicit robust male aggression. Read More
