Lack of information on gender differences in the package inserts of prescription drugs in Japan.

The package inserts of prescription drugs provide essential information for the proper administration of pharmacotherapy. The incidence of adverse reactions for several drugs is known to be higher in women than in men. However, no studies have examined whether information on gender differences is included in Japanese package inserts.

Effect of TNIK upregulation on JQ1-resistant human colorectal cancer HCT116 cells.

JQ1 disrupts the binding of bromodomain and extra-terminal (BET) family of proteins to acetylated histones, modulates the expression of various genes, and inhibits the proliferation of cancer cells. We established two JQ1-resistant sublines from human colorectal cancer HCT116 cells. These resistant cells showed an 8- to 9-fold higher resistance to JQ1, and a 2- to 4-fold higher resistance to various anti-cancer agents, such as doxorubicin, etoposide, mitoxantrone, SN-38, cisplatin, and methotrexate than the parental HCT116 cells.

STAT1 upregulates glutaminase and modulates amino acids and glutathione metabolism.

We previously reported the upregulation of cellular Glu and glutathione levels in human ABCB5- and murine Abcb5-transfected cells. Here, we demonstrate the upregulation of STAT1 and glutaminase (GLS) in ABCB5/Abcb5-transfected cells. Among a total of four ABCB5/Abcb5 high-expressing clones with docetaxel resistance, three of the clones expressed STAT1 and GLS highly and showed resistance to docetaxel and buthionine sulfoximine (BSO), an inhibitor of glutathione synthesis.

SNAIL- and SLUG-induced side population phenotype of HCT116 human colorectal cancer cells and its regulation by BET inhibitors.

Epithelial-mesenchymal transition (EMT) is associated with cancer malignancies such as invasion, metastasis, and drug resistance. In this study, HCT116 human colorectal cancer cells were transduced with SLUG or SNAIL retroviruses, and EMT cells with mesenchymal morphology were established. The EMT cells showed a high invasive activity and resistance to several anticancer agents such as methotrexate, SN-38, and cisplatin.

Upregulation of cellular glutathione levels in human ABCB5- and murine Abcb5-transfected cells.

Background: Previously, we have demonstrated that human ABCB5 is a full-sized ATP-binding cassette transporter that shares strong homology with ABCB1/P-glycoprotein. ABCB5-transfected cells showed resistance to taxanes and anthracyclines. Herein, we further screened ABCB5 substrates, and explored the mechanism of resistance.

Total synthesis of (+)-lasonolide A.

[structure: see text]. An enantiocontrolled total synthesis of (+)-lasonolide A has been accomplished by using the sequential cross metathesis and macrolactonization for the key assembly of the 20-membered polyene macrolide core of the natural product.

Viscoelastic and light scattering studies on thermally induced sol to gel phase transition in fish myosin solutions.

Viscoelastic (VE) and dynamic light scattering (DLS) analyses of fish (white croaker) myosin solutions were performed at myosin concentrations of 30 mg/mL for VE and 0.1 mg/mL for DLS at 0.6M KCl and pH 7.
