Evaluation of the PK/PD Changes on MASLD‐Related Population—An Example From Simultaneous Acetaminophen Parent‐Metabolite PBPK/PD Modeling

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 1, January 2026.
ABSTRACT Patients with metabolic dysfunction‐associated steatotic liver disease (MASLD) may exhibit altered pharmacokinetics (PK) and pharmacodynamics (PD) of drugs compared with healthy populations. However, no physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) model has been specifically developed for MASLD.

A burst of ABC genes in the genome of the polyphagous spider mite Tetranychus urticae [PDF]

open access: yes, 2013
Background: The ABC (ATP-binding cassette) gene superfamily is widespread across all living species. The majority of ABC genes encode ABC transporters, which are membrane-spanning proteins capable of transferring substrates across biological membranes by

Expression and DNA methylation of 20S proteasome subunits as prognostic and resistance markers in cancer

open access: yesMolecular Oncology, Volume 19, Issue 12, Page 3729-3749, December 2025.
Comprehensive analysis of genomic mutations, gene expression, DNA methylation, and pathway analysis of TCGA data was carried out to define cancer types in which proteasome subunits expression is associated with worse survival. Albeit the effect of specific proteasome subunits on cellular function, the main role of the proteasome is better evaluated ...

Interactions of anti-COVID-19 drug candidates with hepatic transporters may cause liver toxicity and affect pharmacokinetics

open access: yesScientific Reports, 2021
Transporters in the human liver play a major role in the clearance of endo- and xenobiotics. Apical (canalicular) transporters extrude compounds to the bile, while basolateral hepatocyte transporters promote the uptake of, or expel, various compounds ...

Uric Acid Functions as an Endogenous Modulator of Microglial Function and Amyloid Clearance in Alzheimer's Disease

open access: yesAdvanced Science, Volume 12, Issue 48, December 29, 2025.
Higher serum UA levels are associated with reduced AD risk in epidemiological studies. UA enhances microglial phagocytic capacity primarily by restoring CD36 and TREM2 receptor recycling that is impaired by Aβ exposure. Therapeutically, UA supplementation improves cognitive function and reduces neuropathology in AD mouse model by enhancing microglial ...

Characterization of SN38-resistant T47D breast cancer cell sublines overexpressing BCRP, MRP1, MRP2, MRP3, and MRP4

open access: yesBMC Cancer, 2022
Background Although several novel resistant breast cancer cell lines have been established, only a few resistant breast cancer cell lines overexpress breast cancer resistance proteins (BCRP).

Effect of bile acids on the expression of MRP3 and MRP4: An In vitro study in HepG2 cell line

open access: yesAnnals of Hepatology, 2021
Introduction and objectives: Free and conjugated bile acids (BA's) cannot cross cell membranes; therefore, a particular transport system is required by the cell.

Emerging role of nuclear factor erythroid 2-related factor 2 in the mechanism of action and resistance to anticancer therapies [PDF]

open access: yes, 2019
Nuclear factor E2-related factor 2 (NRF2), a transcription factor, is a master regulator of an array of genes related to oxidative and electrophilic stress that promote and maintain redox homeostasis. NRF2 function is well studied in in vitro, animal and

Tenofovir renal proximal tubular toxicity is regulated By OAT1 and MRP4 transporters [PDF]

open access: yesLaboratory Investigation, 2011
Tenofovir disoproxil fumarate (TDF) is an oral prodrug and acyclic nucleotide analog of adenosine monophosphate that inhibits HIV-1 (HIV) reverse transcriptase. A growing subset of TDF-treated HIV(+) individuals presented with acute renal failure, suggesting tenofovir-associated kidney-specific toxicity.

Upregulation of Cyclooxygenase-2/Prostaglandin E (COX-2/PGE) Pathway Member Multiple Drug Resistance-Associated Protein 4 (MRP4) and Downregulation of Prostaglandin Transporter (PGT) and 15-Prostaglandin Dehydrogenase (15-PGDH) in Triple-Negative Breast Cancer

open access: yesBreast Cancer: Basic and Clinical Research, 2016
Elevated levels of cyclooxygenase-2 (COX-2) and prostaglandin E 2 (PGE 2 ) are indicators of a poor prognosis in breast cancer. Using several independent publicly available breast cancer gene expression databases, we investigated other members of the PGE
