Bortezomib (PS-341), a proteasome inhibitor, has been examined clinically for the treatment of multiple myeloma and several solid tumors. Bortezomib directly induces tumor cell death and has also been reported to inhibit tumor adaptation to hypoxia by functionally inhibiting hypoxia-inducible factor-1alpha (HIF-1alpha). However, the mechanism underlying HIF-1 inhibition by bortezomib remains obscure. In the present study, we demonstrated that bortezomib attenuated the hypoxic induction of erythr

This study describes the complete sequence of the oldest HBV isolate and the most ancient full viral genome known so far.

SIRT1 is an NAD(+)-dependent protein deacetylase induced by metabolic stresses, such as nutrition or oxygen deprivation. Although SIRT1 contributes to aging and metabolic disorders, its role in cancer progression and therapeutic responses remains controversial. Because hypoxia occurs widely in solid tumors, where it provokes drug resistance, we investigated the involvement of SIRT1 in hypoxia-induced chemoresistance. SIRT1 was downregulated in a panel of non-small cell lung carcinoma (NSCLC) cel

Flower-like palladium nanoclusters (FPNCs) are electrodeposited onto graphene electrode that are prepared by chemical vapor deposition (CVD). The CVD graphene layer is transferred onto a poly(ethylene naphthalate) (PEN) film to provide a mechanical stability and flexibility. The surface of the CVD graphene is functionalized with diaminonaphthalene (DAN) to form flower shapes. Palladium nanoparticles act as templates to mediate the formation of FPNCs, which increase in size with reaction time. Th

Amorphous carbon-coated nickel oxide nanofibers (NiC NFs) were fabricated by vapor deposition polymerization and carbonization. The NiC NFs showed a higher electrochemical property and a longer cycling performance than pristine NiO NFs.

Sodium-dependent vitamin C transporters (SVCTs) is known to transport the reduced form of ascorbic acid into the cell, whereas the oxidized form of vitamin C (VC) is moved through a facilitative sugar transporter, such as glucose transporter (GLUT). With regard to the distribution of SVCT1 and -2 within the various organs, they were reported to be expressed in different types of cells. Especially in the central nervous system, only SVCT2 mRNA was expressed mainly in neurons and some types of neu

Various recently introduced minimally invasive treatment modalities are now widely used for enhancing the aging face. In a special, filler is used to increase the volume of tissue, and so understanding the regional thickness and distribution of the facial superficial fat is essential for optimizing minimally invasive procedures. The aim of this study was to establish the overall facial skin and superficial fat thicknesses using a three-dimensional (3D) scanning system. From 53 adult Korean and T

Statural growth in human populations is a sensitive indicator of socio-economic well-being, and improvements in socio-economic status are reflected in secular increases in adult height. In the present study, we investigated the statures of historical Korean societies to show how stature changed over time. Applying Fujii's equation, derived from modern Japanese, to the measurement of femora removed from 15th- to 19th-century Joseon tombs, the average heights of Korean adults during the Joseon dyn

Abstract Although all of the Korean medieval mummies found up to the present time have shown relatively well‐preserved brains, relevant biomedical information has been difficult to acquire owing to the obstacles to obtaining permission to conduct invasive investigations. However, recently we were able to secure permission to investigate, through various forms of examination including dissection, a well‐preserved brain found in a lime‐soil mixture barrier (LSMB) tomb in Yongin, Korea, because the
