Coupling of Active Motion and Advection Shapes Intracellular Cargo Transport

open access: yes, 2012
Intracellular cargo transport can arise from passive diffusion, active motor-driven transport along cytoskeletal filament networks, and passive advection by fluid flows entrained by such motor/cargo motion.

Changes in intracellular ion activities induced by adrenaline in human and rat skeletal muscle [PDF]

open access: yes, 1988
To study the stimulating effect of adrenaline (ADR) on active Na+/K+ transport we used double-barrelled ion-sensitive micro-electrodes to measure the activities of extracellular K+ (aKe) and intracellular Na+ (aNai) in isolated preparations of rat soleus

Kinesin and dynein use distinct mechanisms to bypass obstacles

open access: yeseLife, 2019
Kinesin-1 and cytoplasmic dynein are microtubule (MT) motors that transport intracellular cargoes. It remains unclear how these motors move along MTs densely coated with obstacles of various sizes in the cytoplasm.

Protein trafficking through the endosomal system prepares intracellular parasites for a home invasion [PDF]

open access: yes, 2013
Toxoplasma (toxoplasmosis) and Plasmodium (malaria) use unique secretory organelles for migration, cell invasion, manipulation of host cell functions, and cell egress. In particular, the apical secretory micronemes and rhoptries of apicomplexan parasites

Modular Nanotransporters Deliver Anti-Keap1 Monobody into Mouse Hepatocytes, Thereby Inhibiting Production of Reactive Oxygen Species

open access: yesPharmaceutics
Background/Objectives: The study of oxidative stress in cells and ways to prevent it attract increasing attention. Antioxidant defense of cells can be activated by releasing the transcription factor Nrf2 from a complex with Keap1, its inhibitor protein ...

Syntaxin 16 and syntaxin 5 are required for efficient retrograde transport of several exogenous and endogenous cargo proteins [PDF]

open access: yes, 2007
Retrograde transport allows proteins and lipids to leave the endocytic pathway to reach other intracellular compartments, such as trans-Golgi network (TGN)/Golgi membranes, the endoplasmic reticulum and, in some instances, the cytosol. Here, we have used

Modeling traffic jams in intracellular transport in axons [PDF]

open access: yes, 2008
Irregularities in intracellular traffic in axons caused by mutations of molecular motors may lead to “traffic jams”, which often result in swelling of axons causing various neurodegenerative diseases.

Intracellular Copper Transport in Mammals [PDF]

open access: yesThe Journal of Nutrition, 2004
Copper is an essential cofactor for approximately a dozen cuproenzymes in which copper is bound to specific amino acid residues in an active site. However, free cuprous ions react readily with hydrogen peroxide to yield the deleterious hydroxyl radical.

Roquin recognizes a non-canonical hexaloop structure in the 3′-UTR of Ox40

open access: yesNature Communications, 2016
Roquin is an RNA-binding protein that prevents autoimmunity by limiting expression of receptors such as Ox40. Here, the authors identify an RNA structure that they describe as an alternative decay element, and they characterise its interaction with ...

Posttranslational modifications of GLUT4 affect its subcellular localization and translocation [PDF]

open access: yes, 2013
The facilitative glucose transporter type 4 (GLUT4) is expressed in adipose and muscle and plays a vital role in whole body glucose homeostasis. In the absence of insulin, only ~1% of cellular GLUT4 is present at the plasma membrane, with the vast ...
