H+ és HCO3- transzporterek szabályozása humán pancreas ductus sejtekben = Regulation of H+ and HCO3-Transporters in Human Pancreatic Duct Cells [PDF]

, 2009
A pancreas nedvben található HCO3- ionok kiválasztásáért a pancreas ductus sejtek felelősek. Jelen pályázatban célul tűztük ki, hogy molekuláris biológiai, transzdukciós és mikrofluorescens technikák felhasználásával megértsük a HCO3- szekréció ...

Lactate-proton co-transport and its contribution to interstitial acidification during hypoxia in isolated rat spinal roots [PDF]

, 1993
Exposure of nervous tissue to hypoxia results in interstitial acidification. There is evidence for concomitant decrease in extracellular pH to the increase in tissue lactate.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Effect of a bound anion on the structure and dynamics of halorhodopsin from Natronomonas pharaonis

Structural Dynamics, 2019
Active ion transport across membranes is vital to maintaining the electrochemical gradients of ions in cells and is mediated by transmembrane proteins. Halorhodopsin (HR) functions as a light-driven inward pump for chloride ions. The protein contains all-

Sulphate and Chloride-Dependent Potassium Transport in Human Erythrocytes are Affected by Crude Venom from Nematocysts of the Jellyfish Pelagia noctiluca

Cellular Physiology and Biochemistry, 2013
Background: It has been reported that biologically active compounds extracted from Cnidaria venom may induce damage by oxidative stress. Erythrocytes are constantly exposed to oxidative stresses, which can contribute to sulphydril (SH-) group oxidation ...

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription

FEBS Open Bio, EarlyView.
In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.
