Transport proteins determine drug sensitivity and resistance in a protozoan parasite, Trypanosoma brucei

open access: yesFrontiers in Pharmacology, 2015
Drug resistance in pathogenic protozoa is very often caused by changes to the ‘transportome’ of the parasites. In Trypanosoma brucei, several transporters have been implicated in uptake of the main classes of drugs, diamidines and melaminophenyl ...

Major Intrinsic Proteins in Fungi: A Special Emphasis on the XIP Subfamily

open access: yesJournal of Fungi
The fungal kingdom, with an estimated five million species, has undergone extensive diversification over the past billion years and now occupies a wide array of ecological niches from terrestrial to aquatic ecosystems.

Targeting aquaporin function: potent inhibition of aquaglyceroporin-3 by a gold-based compound. [PDF]

open access: yesPLoS ONE, 2012
Aquaporins (AQPs) are membrane channels that conduct water and small solutes such as glycerol and are involved in many physiological functions. Aquaporin-based modulator drugs are predicted to be of broad potential utility in the treatment of several ...

A Cytoplasmic pH Sensor Redefines Gating in Bacterial Urea Channels and Acid Resistance

open access: yesSmall, EarlyView.
Bacterial survival in acidic environments requires pH‐gated urea channels. Utilizing complementary approaches, we identify a conserved cytoplasmic glutamic acid residue as a pH sensor in UreI channels. Whereas Gram‐positive bacteria rely solely on this sensor, Gram‐negative bacteria employ a dual‐sensor mechanism with periplasmic residues, revealing a ...

Saccharomyces cerevisiae exhibiting a modified route for uptake and catabolism of glycerol forms significant amounts of ethanol from this carbon source considered as ‘non-fermentable’

open access: yesBiotechnology for Biofuels, 2019
Background Due to its inevitable formation during biodiesel production and its relatively high degree of reduction, glycerol is an attractive carbon source for microbial fermentation processes.

Pushing the limits of atomic force microscopy: Emerging methods for speed, resolution, and quantitative analysis

open access: yesJournal of Microscopy, EarlyView.
Abstract Since its introduction 40 years ago, atomic force microscopy (AFM) has transformed nanoscale imaging across the physical and life sciences. In biology, AFM has provided unprecedented insights into nanoscale biomolecular organisation under near‐physiological conditions, revealing structures and interactions inaccessible to many conventional ...

Implication of Renal Aquaporin-3 in Fructose-Induced Metabolic Syndrome and Melatonin Protection [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2016
Introduction: Metabolic Syndrome (MetS) can be induced by ingestion of large amounts of fructose as a consequence of oxidative stress and dyslipidemia.

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

open access: yesJournal of Applied Toxicology, Volume 46, Issue 11, Page 3868-3881, November 2026.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Analysis of aquaporin 9 expression in human epidermis and cultured keratinocytes

open access: yesFEBS Open Bio, 2014
Aquaporin 9 (AQP9) is a member of the aquaglyceroporin family that transports glycerol, urea and other small solutes as well as water. Compared to the expression and function in epidermal keratinocytes of AQP3, another aquaglyceroporin, our knowledge of ...

The Multifaceted Role of Aquaporin-9 in Health and Its Potential as a Clinical Biomarker

open access: yesBiomolecules, 2022
Aquaporins (AQPs) are transmembrane channels essential for water, energy, and redox homeostasis, with proven involvement in a variety of pathophysiological conditions such as edema, glaucoma, nephrogenic diabetes insipidus, oxidative stress, sepsis ...
