Characteristics of interactions at protein segments without non-local intramolecular contacts in the Protein Data Bank.

PLoS One 2018 11;13(12):e0205052. Epub 2018 Dec 11.

School of Life Science and Technology, Tokyo Institute of Technology, Nagatsuda-cho, Midori-ku, Yokohama, Kanagawa, Japan.

The principle of three-dimensional protein structure formation is a long-standing conundrum in structural biology. A globular domain of a soluble protein is formed by a network of atomic contacts among amino acid residues, but regions without intramolecular non-local contacts are often observed in the protein structure, especially in loop, linker, and peripheral segments with secondary structures. Although these regions can play key roles for protein function as interfaces for intermolecular interactions, their nature remains unclear. Read More

Cadmium is a highly neurotoxic heavy metal impairing neurogenesis and induces neurodegenerative disorders. Toxic concentrations of cadmium induce astrocytic apoptosis by depleting intracellular glutathione levels, elevating intracellular calcium levels, altering mitochondria membrane potentials, and activating JNK and PI3K/Akt signaling pathways. Cadmium suppresses cell proliferation in kidney epithelial cells, lung fibroblasts, and primary myelocytes; however, cadmium's effects on proteins regulating oxidative stress, apoptosis, and cell proliferation in astrocytes are less known.

Direct HLA Genetic Comparisons Identify Highly Matched Unrelated Donor/Recipient Pairs with Improved Transplant Outcome.

Biol Blood Marrow Transplant 2018 Dec 8. Epub 2018 Dec 8.

Diagnostic Laboratories and Blood Research Institute, BloodCenter of Wisconsin, part of Versiti, Milwaukee, WI. Electronic address:

HLA matching by allele-level genotyping is largely based on genetic similarity between a few exons which encode the antigen recognition domain (ARD) of the HLA protein. Next-generation sequencing (NGS) can identify HLA genetic polymorphisms in non-ARD encoding exons, introns, and untranslated regions, but the impact of these polymorphisms on hematopoietic cell transplant (HCT) outcomes is unclear. We performed NGS-based sequencing of eleven HLA loci on a well-characterized retrospective cohort of 166 unrelated donor/recipient HCT pairs. Read More

School of Medicine, Institute of Biomedicine, University of Eastern Finland, Kuopio, Finland. Electronic address:

In the vitamin D intervention study VitDbol (NCT02063334) blood samples were drawn directly before an oral bolus (2000 µg vitamin D) and 24 h later. The focus of phase II of VitDbol was the transcriptome-wide analysis of the effects of vitamin D gene expression in human peripheral blood mononuclear cells (PBMCs). All five participants responded in an individual fashion to the bolus by increases in serum levels of the vitamin D metabolites 25-hydroxyvitamin D (25(OH)D) and 1α,25-dihydroxyvitamin D (1,25(OH)D).

Sex differences in the temporal neuromolecular and synaptogenic effects of the rapid-acting antidepressant drug ketamine in the mouse brain.

Neuroscience 2018 Dec 8. Epub 2018 Dec 8.

Department of Biology & Center for Tissue Regeneration and Engineering at Dayton (TREND), University of Dayton, Dayton, Ohio, USA. Electronic address:

Preclinical evidence suggests that ketamine's rapid and sustained antidepressant actions are due to the induction of synaptogenesis in the medial prefrontal cortex (mPFC) and the hippocampus (HIPP), two brain regions implicated in the pathophysiology of major depression. However, research on the neurobiological effects of ketamine has focused almost exclusively on males. Findings from our group and others indicate that female rodents are more reactive to ketamine's antidepressant effects, since they respond to lower doses in antidepressant-predictive behavioral models.

Targeting PKCδ as a Therapeutic Strategy against Heterogeneous Mechanisms of EGFR Inhibitor Resistance in EGFR-Mutant Lung Cancer.

Cancer Cell 2018 Dec;34(6):954-969.e4

Department of Molecular and Cellular Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX 77030, USA; Center for Molecular Medicine and Graduate Institute of Biomedical Sciences, China Medical University, Taichung 404, Taiwan; Department of Biotechnology, Asia University, Taichung 413, Taiwan. Electronic address:

Multiple mechanisms of resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been identified in EGFR-mutant non-small cell lung cancer (NSCLC); however, recurrent resistance to EGFR TKIs due to the heterogeneous mechanisms underlying resistance within a single patient remains a major challenge in the clinic. Here, we report a role of nuclear protein kinase Cδ (PKCδ) as a common axis across multiple known TKI-resistance mechanisms. Specifically, we demonstrate that TKI-inactivated EGFR dimerizes with other membrane receptors implicated in TKI resistance to promote PKCδ nuclear translocation. Read More

BH3-Mimetic Drugs: Blazing the Trail for New Cancer Medicines.

Cancer Cell 2018 Dec;34(6):879-891

The Walter and Eliza Hall Institute of Medical Research, Parkville, VIC 3052, Australia; Department of Medical Biology, The University of Melbourne, Parkville, VIC 3010, Australia. Electronic address:

Defects in apoptotic cell death can promote cancer and impair responses of malignant cells to anti-cancer therapy. Pro-survival BCL-2 proteins prevent apoptosis by keeping the cell death effectors, BAX and BAK, in check. The BH3-only proteins initiate apoptosis by neutralizing the pro-survival BCL-2 proteins.

Biopolymers - Calcium phosphates composites with inclusions of magnetic nanoparticles for bone tissue engineering.

Int J Biol Macromol 2018 Dec 8. Epub 2018 Dec 8.

Grigore T. Popa University of Medicine and Pharmacy, Faculty of Medical Bioengineering, Department of Biomedical Sciences, Iasi, Romania. Electronic address:

Composites based on combination of biopolymers (chitosan, hyaluronic acid and bovine serum albumin or gelatin), calcium phosphates (CP) and magnetic nanoparticles have been prepared by a biomimetic co-precipitation method. The biomimetic strategy is inspired by natural mineralization processes, where the synthesized minerals are usually combined with proteins, polysaccharides or other mineral forms to form composite, in physiological conditions of temperature and pH. The morphology of the magnetic composites, studied using scanning electron microscopy (SEM) indicated a macroporous structure, which influenced the retention of simulated biological fluids.
