Na+-dependent and Na+-independent betaine transport across the apical membrane of rat renal epithelium [PDF]

open access: yes, 2015
The low renal excretion of betaine indicates that the kidney efficiently reabsorbs the betaine filtered by the glomeruli but the mechanisms involved in such a process have been scarcely investigated.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Islatravir Is Not Expected to Be a Victim or Perpetrator of Drug-Drug Interactions via Major Drug-Metabolizing Enzymes or Transporters

open access: yesViruses, 2021
Islatravir (MK-8591) is a nucleoside reverse transcriptase translocation inhibitor in development for the treatment and prevention of HIV-1. The potential for islatravir to interact with commonly co-prescribed medications was studied in vitro ...

Roles for the Uptake\u3csub\u3e2\u3c/sub\u3e Transporter OCT3 in Regulation of Dopaminergic Neurotransmission and Behavior [PDF]

open access: yes, 2019
Transporter-mediated uptake determines the peak concentration, duration, and physical spread of released monoamines. Most studies of monoamine clearance focus on the presynaptic uptake1 transporters SERT, NET and DAT.

Transport of six tyrosine kinase inhibitors: active or passive ? [PDF]

open access: yes, 1995
Transport of erlotinib, gefitinib, sorafenib, sunitinib, dasatinib and crizotinib can be active or passive, which was studied by measuring uptake at low (4 °C; passive) and normal temperature (37 °C; active and passive) and by the use of specific organic

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

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.

Pharmacokinetic Herb-Drug Interactions: Insight into Mechanisms and Consequences [PDF]

open access: yes, 2015
Herbal medicines are currently in high demand, and their popularity is steadily increasing. Because of their perceived effectiveness, fewer side effects and relatively low cost, they are being used for the management of numerous medical conditions ...

Stereoselectivity in Cell Uptake by SLC22 Organic Cation Transporters 1, 2, and 3

open access: yesJournal of Medicinal Chemistry, 2023
Stereoselectivity can be most relevant in drug metabolism and receptor binding. Although drug membrane transport might be equally important for small-molecule pharmacokinetics, the extent of stereoselectivity in membrane transport is largely unknown.
