The physics of structure formation and maintenance of nuclear bodies (NBs), such as nucleoli, Cajal bodies, promyelocytic leukemia bodies, and speckles, in a crowded nuclear environment remains largely unknown. We investigate the role of macromolecular crowding in the formation and maintenance of NBs using computer simulations of a simple spherical model,… (More)
Nanog regulates human and mouse embryonic stem (ES) cell self-renewal activity. Activation of ERKs signaling negatively regulates ES cell self-renewal and induces differentiation, but the mechanisms are not understood. We found that ERK1 binds and phosphorylates Nanog. Activation of MEK/ERKs signaling and phosphorylation of Nanog inhibit Nanog… (More)
Endo-1,4-β-xylanase A (XynA) from Schizophyllum commune was cloned into pPCZαA and expressed in Pichia pastoris GS115. The open reading frame of the xynA gene is composed of 684 bp, encoding 278 amino acids with a molecular weight of 26 kDa. Based on sequence similarity, XynA belongs to the CAZy glycoside hydrolase family 11. The optimal activity of XynA… (More)
Three cystein-tagged cellulases co-immobilized on AuNP and Au-MSNP for the hydrolytic degradation of cellulose. The biochemical properties, stabilities, activities and reusability of these co-immobilized systems were compared to those of mixtures of free cellulases.
Rifampin resistance in Mycobacterium tuberculosis is largely determined by mutations in an 80-bp rifampin resistance determining region (RRDR) of the rpoB gene. We developed a rapid single-well PCR assay to identify RRDR mutations. The assay uses sloppy molecular beacons to probe an asymmetric PCR of the M. tuberculosis RRDR by melting temperature (T(m))… (More)
AIM The mortality and morbidity of end-stage renal failure patients remains high despite recent advances in pre-dialysis care. Previous studies suggesting a positive effect of pre-dialysis education were limited by unmatched comparisons between the recipients and non-recipients of education. The present study aimed to clarify the roles of the… (More)
The cancer microenvironment affects cancer cell proliferation and growth. Embryonic stem (ES)-preconditioned 3-dimensional (3-D) culture of cancer cells induces cancer cell reprogramming and results in a change in cancer cell properties such as differentiation and migration in skin melanoma. However, the mechanism has not yet been clarified. Using the… (More)
Pyruvate is an endogenous antioxidant and anti-inflammatory substance. The present study was implemented to investigate the protective effect of ethyl pyruvate (EP) against the development and progression of diabetic nephropathy in an in vivo and in vitro model. Diabetic rats were prepared by injecting streptozotocin (65 mg/kg). Those that developed… (More)
A new naphthalene derivative containing a urea group at the 1,8-position of naphthalene was synthesized and showed a unique absorption and fluorescence peak with a fluoride ion. Calculations suggested that a new peak was attributed to the increased anion character of urea nitrogen due to the strong interaction of the fluoride and N-H protons.
[structure: see text] Five new urea derivative naphthalene compounds were synthesized by a reaction of 1,8-diaminonaphthalene and the corresponding isocyanates and showed a distinct color change only when treated with fluoride ions.
