SUMOylation regulates LKB1 localization and its oncogenic activity in liver cancer
(Elsevier, 2019-02)
BACKGROUND: Even though liver kinase B1 (LKB1) is usually described as a tumor suppressor in a wide variety of tissues, it has been shown that LKB1 aberrant expression is associated with bad prognosis in Hepatocellular ...
Potential Benefits and Risks for Soil Health Derived From the Use of Organic Amendments in Agriculture
(MDPI, 2019-09-12)
The use of organic amendments in agriculture is a common practice due to their potential to increase crop productivity and enhance soil health. Indeed, organic amendments of different origin and composition (e.g., animal ...
Membrane Repair Mechanisms against Permeabilization by Pore-Forming Toxins
(MDPI, 2018-06-09)
Permeabilization of the plasma membrane represents an important threat for any cell, since it compromises its viability by disrupting cell homeostasis. Numerous pathogenic bacteria produce pore-forming toxins that break ...
Adenylate Cyclase Toxin promotes bacterial internalisation into non phagocytic cells
(Nature Publishing Group, 2015-09-08)
Bordetella pertussis causes whooping cough, a respiratory infectious disease that is the fifth largest cause of vaccine-preventable death in infants. Though historically considered an extracellular pathogen, this bacterium ...
Calpain-Mediated Processing of Adenylate Cyclase Toxin Generates a Cytosolic Soluble Catalytically Active N-Terminal Domain
(Public Library Publishing, 2013-06)
Bordetella pertussis, the whooping cough pathogen, secretes several virulence factors among which adenylate cyclase toxin (ACT) is essential for establishment of the disease in the respiratory tract. ACT weakens host ...
On the Dynamics of the Adenylate Energy System: Homeorhesis vs Homeostasis
(Public Library Science, 2014-10-10)
Biochemical energy is the fundamental element that maintains both the adequate turnover of the biomolecular structures and the functional metabolic viability of unicellular organisms. The levels of ATP, ADP and AMP reflect ...
Advantages and Versatility of Fluorescence-Based Methodology to Characterize the Functionality of LDLR and Class Mutation Assignment
(Public Library Science, 2014-11-11)
Familial hypercholesterolemia (FH) is a common autosomal codominant disease with a frequency of 1:500 individuals in its heterozygous form. The genetic basis of FH is most commonly mutations within the LDLR gene. Assessing ...
Ca2+ Influx and Tyrosine Kinases Trigger Bordetella Adenylate Cyclase Toxin (ACT) Endocytosis. Cell Physiology and Expression of the CD11b/CD18 Integrin Major Determinants of the Entry Route
(Public Library Publishing, 2013-09)
Humans infected with Bordetella pertussis, the whooping cough bacterium, show evidences of impaired host defenses. This pathogenic bacterium produces a unique adenylate cyclase toxin (ACT) which enters human phagocytes and ...
Human LDL Structural Diversity Studied by IR Spectroscopy
(Public Library Science, 2014-03-18)
Lipoproteins are responsible for cholesterol traffic in humans. Low density lipoprotein (LDL) delivers cholesterol from liver to peripheral tissues. A misleading delivery can lead to the formation of atherosclerotic plaques. ...
Role of Monoubiquitylation on the Control of IκBα Degradation and NF-κB Activity
(Public Library of Science, 2011-10-12)
The NF-κB pathway is regulated by multiple post-translational modifications including phosphorylation, ubiquitylation and SUMOylation. Many of these modifications act on the natural inhibitor IκBα modulating its capacity ...
