Evolution of Conjugation and Type IV Secretion Systems [PDF]

Molecular Biology and Evolution, 2012
Genetic exchange by conjugation is responsible for the spread of resistance, virulence, and social traits among prokaryotes. Recent works unraveled the functioning of the underlying type IV secretion systems (T4SS) and its distribution and recruitment for other biological processes (exaptation), notably pathogenesis.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

LC3 conjugation system in mammalian autophagy

The International Journal of Biochemistry & Cell Biology, 2004
Autophagy is the bulk degradation of proteins and organelles, a process essential for cellular maintenance, cell viability, differentiation and development in mammals. Autophagy has significant associations with neurodegenerative diseases, cardiomyopathies, cancer, programmed cell death, and bacterial and viral infections.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Highly Conducting pi-Conjugated Molecular Junctions Covalently Bonded to Gold Electrodes

, 2011
We measure electronic conductance through single conjugated molecules bonded to Au metal electrodes with direct Au-C covalent bonds using the scanning tunneling microscope based break-junction technique.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Significantly Enhanced Molecular Stacking in Ternary Bulk Heterojunctions Enabled by an Appropriate Side Group on Donor Polymer

Advanced Science, 2020
Ternary strategy is a promising approach to broaden the photoresponse of polymer solar cells (PSCs) by adopting combinatory photoactive blends. However, it could lead to a more complicated situation in manipulating the bulk morphology. Achieving an ideal

Perinatal development of conjugative enzyme systems. [PDF]

Environmental Health Perspectives, 1976
The problems and priorities involved in studying the role of conjugagive enzymes in developmental pharmacology are discussed and evaluated. The relative rates of UDP glucuronyltransferase and beta-glucuronidase were studied during perinatal development in hepatic and extrahepatic tissues to determine the net balance of glucuronidation or ...

Conjugate Duality and the Control of Linear Discrete Systems [PDF]

Journal of Optimization Theory and Applications, 2013
The goal of the paper is to develop a duality theory for the problem of minimizing a convex function over the solution set of a range inclusion problem determined by a multivalued operator with a convex graph, as it occurs, for example, in optimal control when the constraint set is described by linear discrete systems or differential inclusions. A dual
