Heating-mediated purification of active FGF21 and structure-based design of its variant with enhanced potency.

Fibroblast growth factor 21 (FGF21) has pharmaceutical potential against obesity-related metabolic disorders, including non-alcoholic fatty liver disease. Since thermal stability is a desirable factor for therapeutic proteins, we investigated the thermal behavior of human FGF21. FGF21 remained soluble after heating; thus, we examined its temperature-induced structural changes using circular dichroism (CD).

Pralatrexate Sustainably Released from Polypeptide Thermogel Is Effective for Chondrogenic Differentiation of Mesenchymal Stem Cells.

Folic acid was reported to significantly improve chondrogenic differentiation of mesenchymal stem cells. In a similar mechanism of action, we investigated clinically approved antifolates by the U.S.

Comparison of genome-wide gene expression patterns in the seedlings of nascent allohexaploid wheats produced by two combinations of hybrids.

Allopolyploidization in plants is an important event that enhances heterosis and environmental adaptation. Common wheat, Triticum aestivum (AABBDD), which is an allohexaploid that evolved from an allopolyploidization event between T. turgidum (AABB) and Aegilops tauschii (DD), shows more growth vigor and wider adaptation than tetraploid wheats.

Changes in genome-wide gene expression during allopolyploidization and genome stabilization in hexaploid wheat.

Allopolyploidization is an important evolutionary event in plants, but its genome-wide effects are not fully understood. Common wheat, Triticum aestivum (AABBDD), evolved through amphidiploidization between T. turgidum (AABB) and Aegilops tauschii (DD).

Three-dimensional remodeling of mitral valve in patients with significant regurgitation secondary to rheumatic versus prolapse etiology.

The present study aimed to investigate geometric remodeling of the mitral valve (MV) and to identify the geometric determinants of mitral regurgitation (MR) severity in patients with significant MR secondary to a rheumatic or prolapse etiology. We studied 90 consecutive patients in normal sinus rhythm, including 70 patients showing significant MR (52 with prolapsed/flail and 18 with rheumatic MV) and 20 controls with normal MV without MR. A full volume image was acquired using transesophageal echocardiography, and geometric analysis of the MV leaflet was performed with dedicated software.

Differential regulation of vimentin mRNA by 12-O-tetradecanoylphorbol 13-acetate and all-trans-retinoic acid correlates with motility of Hep 3B human hepatocellular carcinoma cells.

Vimentin is a growth-related gene and often expressed when epithelial cells are stimulated to proliferate by growth factors. In cancer, vimentin expression is associated with a dedifferentiated malignant phenotype, increased motility, invasive ability and poor prognosis. We studied the regulation of vimentin mRNA and multistep invasion processes following treatment of 12-O-tetradecanoylphorbol 13-acetate (TPA) and all-trans-retinoic acid (RA) in Hep 3B hepatocellular carcinoma cells.
