The yeast H+-ATPase Pma1 promotes Rag/Gtr-dependent TORC1 activation in response to H+-coupled nutrient uptake

open access: yeseLife, 2018
The yeast Target of Rapamycin Complex 1 (TORC1) plays a central role in controlling growth. How amino acids and other nutrients stimulate its activity via the Rag/Gtr GTPases remains poorly understood.

Structure, function and plasticity of GABA transporters

open access: yesFrontiers in Cellular Neuroscience, 2014
GABA transporters belong to a large family of neurotransmitter:sodium symporters. They are widely expressed throughout the brain, with different levels of expression in different brain regions.

Metabolic Profiles of Carbohydrates in Streptococcus thermophilus During pH-Controlled Batch Fermentation

open access: yesFrontiers in Microbiology, 2020
Revealing the metabolic profiles of carbohydrates with their regulatory genes and metabolites is conducive to understanding their mechanism of utilization in Streptococcus thermophilus MN-ZLW-002 during pH-controlled batch fermentation.

About P systems with symport/antiport [PDF]

open access: yesSoft Computing, 2004
It is proved that four membranes su±ce to P systems with minimal symport/antiport to generate all recursively enumerable sets of numbers. It is also proved that P systems with symport/antiport without maximal par- allelism are equivalent to partially blind counter automata.

Genome-Wide Identification and Transcript Analysis Reveal Potential Roles of Oligopeptide Transporter Genes in Iron Deficiency Induced Cadmium Accumulation in Peanut

open access: yesFrontiers in Plant Science, 2022
The oligopeptide transporter (OPT) family is a group of proton-coupled symporters that play diverse roles, including metal homeostasis. However, little is known about this family of peanuts.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Molecular determinants for the thermodynamic and functional divergence of uniporter GLUT1 and proton symporter XylE. [PDF]

open access: yesPLoS Computational Biology, 2017
GLUT1 facilitates the down-gradient translocation of D-glucose across cell membrane in mammals. XylE, an Escherichia coli homolog of GLUT1, utilizes proton gradient as an energy source to drive uphill D-xylose transport.

Bisphenol A Induces DNA Damage and Differential Cytotoxicity in Thyroid Cells: High‐Dose Effects Challenge Regulatory Thresholds

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a ubiquitous environmental endocrine disruptor, has been implicated in carcinogenesis; however, its effects on thyroid cells remain unclear. This study investigated BPA‐induced cytotoxicity and genotoxicity in thyroid cell lines, including normal follicular (Nthy‐ori 3‐1), papillary carcinoma (TPC‐1 and BCPAP) and anaplastic
