The superfamily of organic anion transporting polypeptides

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2003
Organic anion transporting polypeptides (Oatps/OATPs) form a growing gene superfamily and mediate transport of a wide spectrum of amphipathic organic solutes. Different Oatps/OATPs have partially overlapping and partially distinct substrate preferences for organic solutes such as bile salts, steroid conjugates, thyroid hormones, anionic oligopeptides ...

Inhibition of Human Drug Transporter Activities by the Pyrethroid Pesticides Allethrin and Tetramethrin. [PDF]

open access: yesPLoS ONE, 2017
Pyrethroids are widely-used chemical insecticides, to which humans are commonly exposed, and known to alter functional expression of drug metabolizing enzymes. Limited data have additionally suggested that drug transporters, that constitute key-actors of

The Organic Anion Transporter (OATP) Family

open access: yesDrug Metabolism and Pharmacokinetics, 2004
In the last decade, many organic anion transporters have been isolated, characterized their distribution and substrates. The recently identified organic anion transporter family OATP (organic anion transporting polypeptide)/LST (liver-specific transporter) family, transport bile acids, hormones as well as eicosanoids, various compounds (BSP, HMG-CoA ...

Assessment of the Drug Interaction Potential of Unconjugated and GalNAc3-Conjugated 2′-MOE-ASOs

open access: yesMolecular Therapy: Nucleic Acids, 2017
Antisense oligonucleotides are metabolized by nucleases and drug interactions with small drug molecules at either the cytochrome P450 (CYP) enzyme or transporter levels have not been observed to date.

A single high-dose irradiation changes accumulation of methotrexate and gene expression levels of SLC and ABC transporters in cancer cells

open access: yesFrontiers in Pharmacology, 2023
Chemoradiotherapy is frequently used to treat cancer. Stereotactic body radiotherapy (SBRT) is a single high-dose radiotherapy used to treat a variety of cancers.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Human Organic Anion Transporters Mediate the Transport of Tetracycline

open access: yesJapanese Journal of Pharmacology, 2002
The purpose of this study was to elucidate the molecular mechanism for renal tetracycline transport by human organic anion transporters (hOATs) using proximal tubular cells stably expressing hOATs. The cells stably expressing hOAT1, hOAT2, hOAT3 and hOAT4 exhibited a higher amount of [3H]tetracycline uptake compared with mock cells.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Regulation of renal organic anion transporters

open access: yes, 2019
Organic anion transporters (OATs) are a group of membrane proteins that are mainly involved in the body disposition of organic anionic molecules or zwitterions, including a diverse array of clinical therapeutics, environmental toxins, and endogenous ...
