Admixture Mapping Reveals Candidate Regions for Methotrexate Neurotoxicity Susceptibility: A Reducing Disparities in Acute Leukemia Consortium Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Neurotoxicity is a rare, often dose‐limiting adverse effect of methotrexate (MTX) therapy that disproportionally affects Latino children. Factors contributing to the observed disparity are not well understood. This study leveraged admixture mapping to identify genetic regions associated with MTX‐related neurotoxicity susceptibility ...

Potential contributors to low dose methotrexate toxicity in a patient with rheumatoid arthritis and pernicious anemia: case report

BMC Rheumatology, 2021
Background Low dose methotrexate toxicity rarely occurs, but may present with severe complications, such as pancytopenia, hepatotoxicity, mucositis, and pneumonitis.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma

Molecular Oncology, EarlyView.
Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Factors related to dosing frequency and route of administration in methotrexate intolerance among patients with rheumatoid arthritis: a cross-sectional study

Therapeutic Advances in Drug Safety
Background: Methotrexate is central to the management of rheumatoid arthritis (RA). However, its use is often limited by methotrexate intolerance. Objectives: This study aims to explore the association between alternative methotrexate dosing methods and ...

The redox state of cytochrome c modulates resistance to methotrexate in human MCF7 breast cancer cells.

PLoS ONE, 2013
BackgroundMethotrexate is a chemotherapeutic agent used to treat a variety of cancers. However, the occurrence of resistance limits its effectiveness. Cytochrome c in its reduced state is less capable of triggering the apoptotic cascade.

Nitric oxide plays a critical role in methotrexate-induced hyperplasia of enterochromaffin cells containing 5-hydroxytryptamine in rat small intestine

Journal of Pharmacological Sciences, 2019
The role of nitric oxide (NO) in the changes in enterochromaffin cells and ileal 5-hydroxytryptamine (5-HT) content induced by a single i.p. administration of methotrexate was investigated in rats.

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

The pharmacogenetics of methotrexate [PDF]

Rheumatology, 2007
Methotrexate (MTX) is a cornerstone of therapy for rheumatoid arthritis. However, it is not universally effective and up to one-third of patients fail to respond to treatment, either because of inefficacy or adverse events, although at present it is not possible to predict therapy response accurately.

A Systematic Review and Meta‐Analysis of the Recurrence of Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune encephalitis (AE) is a disease with a potential for recurrence, and patients receive immunotherapy to prevent it. However, there is no consensus on the duration of immunotherapy. This study aimed to determine the recurrence rate and identify the risk factors for AE to provide guidance on the duration of immunotherapy ...
