Characterization of the Intrinsic Phospholipase A1 Activity of Bordetella pertussis Adenylate Cyclase Toxin
(MDPI, 2018-12-04)
Adenylate cyclase toxin (ACT, CyaA) is one of the important virulence factors secreted by the whooping cough bacterium Bordetella pertussis, and it is essential for the colonization of the human respiratory tract by this ...
Ubiquitylation Dynamics of the Clock Cell Proteome and TIMELESS During a Circadian Cycle
(Cell Press, 2018-05-22)
Circadian clocks have evolved as time-measuring molecular devices to help organisms adapt their physiology to daily changes in light and temperature. Transcriptional oscillations account for a large fraction of rhythmic ...
The role of the Wnt receptor frizzled-8 in prostate cancer pathogenesis.
(2018-11-30)
Wnt-11 es un miembro no canónico de la familia de Wnt que se observa altamente expresado en líneas celulares de cáncer de próstata, así como en tumores de próstata. Wnt-11 promueve la migración y la invasión celular lo que ...
Structural basis for substrate recognition and catalysis of the mycobacterial acyltransferase pata
(2018-02-22)
Los glicolípidos desempeñan un papel central en una variedad de procesos biológicos importantes en todos los organismos vivos. PatA es una aciltransferasa asociada a la membrana implicada en la biosíntesis de fosfatidil- ...
In vitro characterization of LDLR, PCSK9 and APOB variants as a tool to understand molecular aspects of familial hypercholesterolemia and improving genetic diagnosis.
(2018-12-19)
La hipercolesterolemia familiar es una enfermedad genética autosómica dominante que se caracteriza por unos niveles altos de colesterol en plasma. Este colesterol, con el tiempo se acumula en las paredes vasculares y ...
Replacement of Cysteine at Position 46 in the First Cysteine-Rich Repeat of the LDL Receptor
(Public Library Science, 2018-10-17)
Background and aims
Pathogenic mutations in the Low Density Lipoprotein Receptor gene (LDLR) cause Familial Hypercholesterolemia (FH), one of the most common genetic disorders with a prevalence as high as 1 in 200 in ...
Characterization of wnt signaling in tamoxifen resistant breast cancer stem/progenitor cells
(2018-12-20)
El tamoxifen, un antagonista de ER, es el tratamiento más común empleado para tratar a pacientes que expresan ER. Las células resistentes a tamoxifen están enriquecidas en células madre/progenitoras. La expresión de WNT1 ...
Lipidomimetic Compounds Act as HIV-1 Entry Inhibitors by Altering Viral Membrane Structure
(Frontiers Media, 2018-09-04)
The envelope of Human Immunodeficiency Virus type 1 (HIV-1) consists of a liquid-ordered membrane enriched in raft lipids and containing the viral glycoproteins. Previous studies demonstrated that changes in viral membrane ...
Celiac Diasease-associated lncRNA Named HCG14 Regulates NOD1 Expression in Intestinal Cells
(Wiley, 2018-08-01)
Objective:
The aim of the study is to identify additional celiac disease associated loci in the major histocompatibility complex (MHC) independent from classical HLA risk alleles (HLA-DR3-DQ2) and to characterize their ...
DEXI, a candidate gene for type 1 diabetes, modulates rat and human pancreatic beta cell inflammation via regulation of the type I IFN/STAT signalling pathway
(Springer, 2018-11-26)
Aims/hypothesis: The initial stages of type 1 diabetes are characterized by an aberrant islet inflammation that is in part regulated by the interaction between type 1 diabetes susceptibility genes and environmental factors. ...
