What is Membrane Transport? At the heart of cellular biology lies the essential phenomenon of membrane transport. This intricate process ensures the smooth movement of various molecules, ions, and substances across cell membranes. Its importance resonates in maintaining the cellular environment, enabling...
These glial cells facilitate brain homeostasis, form myelin and provide neuronal structure and support8, consistent with evidence of RNA transport across and the permeability of the blood–brain barrier16,17 and that some brain regions are in direct contact with the blood18. Similarly, we used ...

Im Gegensatz dazu wird das Schilddrüsenhormon Thyroxin (T4) in seine aktive Form Trijodthyronin (T3) umgewandelt und durch die Plasmamembran transportiert. Innerhalb der Zelle liegen die Schilddrüsenhormonrezeptoren in einem Komplex mit der Zellkern-DNA vor. Das Schilddrüsenhormon bindet dann...
Hypoxia, in biology, condition in which tissues of the body are starved of oxygen. Diseases of the blood, the heart and circulation, and the lungs may all produce some form of hypoxia. In its extreme form, where oxygen is entirely absent, the condition i

We show here that taxol has different effects on different ...
Nucleoside transport regulation in undifferentiated Neuro-2A cells has been studied and found to include Na+-dependent adenosine transport and facilitated diffusion adenosine transport. The latter corresponded to nitrobenzylthioinosine-sensitive nucleoside transport. Short-term treatment of Neuro-2A cells with...
Container vessels are the workhorses of global trade, designed to efficiently transport standardized cargo containers across the world’s oceans. These ships feature a distinctive box-like structure, facilitating the secure stowage of containers in a uniform manner. Known for their high carrying capacit...
It is a long established fact that sex is an important factor that influences the transcriptional regulatory processes of an organism. However, understanding sex-based differences in gene expression has been limited because existing studies typically seq
