Biophysical and Structural Studies on the Capsid Protein of the Human Immunodeficiency Virus Type 1: A New Drug Target? by José L. Neira

“…In the first part of this work, I shall review the biophysical studies carried out with the dimeric wild-type CAC protein and a mutant monomeric variant. The results open new venues for the development of drugs able to interact either with the dimeric species, hampering its assembly, or with the monomeric species, obstructing its folding. …”

GENETIC AND MOLECULAR ANALYSIS OF COMPLEMENTATION OF THE FLAMENCO AND PIWI LOCI IN DROSOPHILA MELANOGASTER by F. A. Urusov, L. N. Nefedova, A. R. Lavrenov, N. I. Romanova, A. I. Kim

“…This paper discusses the results of the complementation test, which involves crossing strains MS and SS, mutant for the flamenco locus, with the piwi strain 3, heterozygous for a mutation in the piwi gene, followed by study of the transcription level of gypsy in the ovaries and testes of hybrids derived from these crosses. …”

Pseudorabies virus infection triggers pUL46-mediated phosphorylation of connexin-43 and closure of gap junctions to promote intercellular virus spread. by Alexander Tishchenko, Nicolás Romero, Cliff Van Waesberghe, Jonas L Delva, Oliver Vickman, Gregory A Smith, Thomas C Mettenleiter, Walter Fuchs, Barbara G Klupp, Herman W Favoreel

“…Consequently, a UL46null PRV mutant is unable to phosphorylate Cx43 or inhibit GJIC and displays reduced intercellular spread, which is effectively rescued by pharmacological inhibition of GJIC. …”

sNASP Mutation Aggravates to the TLR4-Mediated Inflammation in SLE by TAK1 Pathway by Yatao Bao, Meng Lian, Yong Chen, Xiaotian Gu, Kunyu Cao, Xiaoping Du, Jiyu Ju

“…In previous studies, we found that the mutant somatic nuclear autoantigenic sperm protein (sNASP) gene in the mouse lupus susceptibility locus Sle2 can promote the development of lupus model mice, but the mechanism is still unclear. …”

Disorders in brassinosteroids signal transduction triggers the profound molecular alterations in the crown tissue of barley under drought. by Anetta Kuczyńska, Martyna Michałek, Piotr Ogrodowicz, Michał Kempa, Paweł Krajewski, Vladimiro Cardenia, Maria Teresa Rodriguez-Estrada, Marina Pérez-Llorca, Sergi Munné-Bosch, Krzysztof Mikołajczak

“…Large-scale transcriptomic and proteomic profiling confirmed the specific re-modeling of behavior of the BRs-insensitive barley uzu1.a mutant under drought. On the other hand, a set of genes expressed independently of the genotype was identified, including dehydrin encoding genes. …”

Nicotine Has a Therapeutic Window of Effectiveness in a Drosophila melanogaster Model of Parkinson’s Disease by Brady T. Mannett, Braden C. Capt, Krista Pearman, Lori M. Buhlman, John M. VandenBrooks, Gerald B. Call

“…We show that continuous early nicotine administration improves both climbing and flight deficiencies present in homozygous park25 mutant PD model Drosophila melanogaster. Using a new climbing assay, we identify several climbing deficiencies in this PD model that are improved or rescued by continuous nicotine treatment. …”

Mice with Catalytically Inactive Cathepsin A Display Neurobehavioral Alterations by O. Y. Calhan, V. Seyrantepe

“…Previous in vitro studies have shown that CathA has specific activity against vasoactive peptides and neuropeptides, including endothelin-1 and oxytocin. A mutant mouse with catalytically inactive CathA enzyme (CathAS190A) shows increased levels of endothelin-1. …”

The Role of the Immune System in Huntington’s Disease by Gisa Ellrichmann, Christiane Reick, Carsten Saft, Ralf A. Linker

“…Huntington’s disease (HD) is characterized by a progressive course of disease until death 15–20 years after the first symptoms occur and is caused by a mutation with expanded CAG repeats in the huntingtin (htt) protein. Mutant htt (mhtt) in the striatum is assumed to be the main reason for neurodegeneration. …”
