Twelve novel single nucleotide polymorphisms (SNPs) were found in the gene encoding the ATP-binding cassette transporter, P-glycoprotein, from 60 Japanese individuals who were administered the anti-antiarrythmic drug, amiodarone. The detected SNPs were as follows: 1) SNP, MPJ6_AB1017 (IVS6-109); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 2) SNP, MPJ6_AB1018 (IVS7+14); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 3) SNP, MPJ6_AB1021 (IVS9-44); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 4) SNP, MPJ6_AB1052 (IVS12+17); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 5) SNP, MPJ6_AB1029 (IVS15-69); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 6) SNP, MPJ6_AB1040 (IVS24+16); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 7) SNP, MPJ6_AB1053 (IVS27-189); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 8) SNP, MPJ6_AB1054 (IVS27-172); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 9) SNP, MPJ6_AB1048 (IVS27-167); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 10) SNP, MPJ6_AB1055 (IVS27-152); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 11) SNP, MPJ6_AB1049 (IVS27-119); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 12) SNP, MPJ6_AB1051 (at nucleotide 3751 (exon 28) from the A of the translation initiation codon); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168. Among these SNPs, only MPJ6_AB1051 resulted in an amino acid alteration, V1251I.

: The multiple drug-resistant phenomenon has long since plagued the effectiveness of various chemotherapies used in the treatment of patients with glioblastoma (GBM), which is still incurable to this day. ATP-binding cassette (ABC) transporters function as drug transporters and have been touted to be the main culprits in developing resistance to xenobiotic drugs in GBM. : This review systematically analyzed the efficacy of ABC transporters against various anticancer drugs from 16 studies identified from five databases (PubMed, Medline, Embase, Scopus, and ScienceDirect).

Mesenchymal stem cells (MSCs) are multipotent cells with the potential to differentiate into various lineages. They have also the potential to protect themselves against harmful stimuli to maintain their functional integrity. Drug resistance-related transporters such as ABCB1 (P-glycoprotein; P-gp), ABCC1 (MRP1; multidrug resistance-related Protein 1), and LRP (lung resistance protein) may protect MSCs against toxic substances such as chemotherapeutic agents.

Objective: This study aimed to investigate the synergistic effects of the chemotherapy drug Carfilzomib (CFZ) and Pistachio hull extract on the SK-BR3 breast cancer cell line.
Methods: In this experimental study, we evaluated the effect of Pistachio hull extract and CFZ as standalone treatments on cell viability using the MTT assay at 24- and 48-hours post-treatment. Following this, we conducted combination therapy analyses to assess the potential synergistic relationship between Pistachio hull extract and CFZ after 24- and 48-hours of treatment on both the SK-BR3 breast cancer cell line and the MCF10A normal cell line.
Pharmacogenetic Testing in Treatment-resistant Panic Disorder: a Preliminary Analysis.

Laboratory of Panic and Respiration, Instituto de Psiquiatria, Universidade Federal do Rio de Janeiro (UFRJ). Rio de Janeiro, RJ, Brazil.
Background: Many pharmacological treatments are considered effective in the treatment of panic disorder (PD), however, about 20 to 40% of the patients have treatment-resistant PD. Pharmacogenetics could explain why some patients are treatment-resistant.
Objective: Our objective was to gather preliminary data on the clinical usefulness of pharmacogenetic testing in this disorder.

Objective: To study the associations of genetic markers influencing the residual reactivity of platelets during antiplatelet therapy with acetylsalicylic acid, and clinical and laboratory parameters, including parameters of the platelet hemostasis, in patients with non-cardioembolic ischemic stroke (IS) for a deeper understanding of the pathogenetic mechanisms and prediction of response to therapy and clinical outcome.
Material And Methods: The study included 296 patients (average age 64.65 [55; 76] years) undergoing treatment at the City Clinical Hospital named after.
