Endoglin Is Essential for the Maintenance of Self-Renewal and Chemoresistance in Renal Cancer Stem Cells. [PDF]

, 2017
Renal cell carcinoma (RCC) is a deadly malignancy due to its tendency to metastasize and resistance to chemotherapy. Stem-like tumor cells often confer these aggressive behaviors.

Interindividual epigenetic variation in ABCB1 promoter and its relationship with ABCB1 expression and function in healthy Chinese subjects [PDF]

British Journal of Clinical Pharmacology, 2015
AimInterindividual epigenetic variation is likely to be an important mechanism contributing to the interindividual variability in the expression and function of ATP‐binding cassette, sub‐family B, member 1 (ABCB1). The aim of the present study was to explore the effect of interindividual epigenetic variability in the ABCB1 promoter on ABCB1 expression ...

Osimertinib (AZD9291), a Mutant-Selective EGFR Inhibitor, Reverses ABCB1-Mediated Drug Resistance in Cancer Cells

Molecules, 2016
In recent years, tyrosine kinase inhibitors (TKIs) have been shown capable of inhibiting the ATP-binding cassette (ABC) transporter-mediated multidrug resistance (MDR). In this study, we determine whether osimertinib, a novel selective, irreversible EGFR

Differential effect of ABCB1 haplotypes on promoter activity [PDF]

Pharmacogenetics and Genomics, 2018
Promoter single-nucleotide polymorphisms (SNPs) of the ABCB1 gene, encoding the placental efflux transporter P-glycoprotein, can affect its expression and alter xenobiotic transfer from the maternal to the fetal circulation. Because SNPs are arranged in specific combinations as defined haplotypes, the aims of this study were to: (i) determine the ...

Bone morphogenetic protein 7 sensitizes O6-methylguanine methyltransferase expressing-glioblastoma stem cells to clinically relevant dose of temozolomide. [PDF]

, 2015
BackgroundTemozolomide (TMZ) is an oral DNA-alkylating agent used for treating patients with glioblastoma. However, therapeutic benefits of TMZ can be compromised by the expression of O6-methylguanine methyltransferase (MGMT) in tumor tissue.

Understanding and Overcoming Antibody‐Drug Conjugate Resistance: Biological Mechanisms and Emerging Analytical Frameworks in Breast Cancer

Advanced Science, EarlyView.
Antibody–drug conjugates (ADCs) transform breast cancer therapy, yet resistance limits their durability. Emerging evidence reveals that ADC failure is not solely tumor‐intrinsic but shaped by dynamic tumor–microenvironment interactions that alter drug delivery, processing, and response.

Effect of developmental changes on pharmacokinetics of drugs used in the treatment of infant acute lymphoblastic leukaemia—A comprehensive review

British Journal of Clinical Pharmacology, EarlyView.
While the event‐free survival (EFS) of children treated for acute lymphoblastic leukaemia (ALL) has improved greatly in the last decades, the EFS for patients diagnosed with ALL before the age of one is still under 50%. This outcome further decreases when infants have a rearrangement in the gene encoding histone‐lysine N‐methyltransferase 2A (KMT2A ...

Presence of the ABCB1 (MDR1) deletion mutation causing ivermectin hypersensitivity in certain dog breeds in Belgium [PDF]

, 2009
Hypersensitivity to ivermectin and certain other drugs in Collies and related breeds is caused by a 4-base pair deletion mutation in the ABCB1 gene, better known as the MDR1 gene, encoding P-glycoprotein.

Association between ABCB1 Immunohistochemical Expression and Overall Survival in Gastric Cancer Patients [PDF]

, 2014
Gastric cancer (GC) is one of the most common malignancies worldwide. the ABCB1 protein, a member of the ATP-binding cassette (ABC) transporter family, encoded by the ABCB1 gene, considerably influences the distribution of drugs across cell membranes as ...

Assessing transporter‐mediated rifampin–linezolid interaction using physiologically‐based pharmacokinetic modelling

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims The study aims to develop a physiologically‐based pharmacokinetic (PBPK) model to quantitatively evaluate the role of ATP‐binding cassette sub‐family B member 1 (ABCB1) and ATP‐binding cassette super‐family G member 2 (ABCG2) in the drug–drug interaction (DDI) between rifampin and linezolid and to predict the impact of high‐dose rifampin ...
