Anti-IZUMO1PFF VHH (variable domain of camelid heavy chain antibody) clones, N6 and N15, from immunized alpaca (Lama pacos) phage library were efficiently expressed and their VHH products were secreted into the culture medium of Brevibacillus choshinensis HPD31-SP3, e.g., at a level of 26-95mg in 100ml conventional flask culture. With a 3-L scale fed-batch(More)
UNLABELLED Expression of an osteogenic cytokine, IL-11, is decreased in SAMP6. We show here that IL-11 transcription largely depends on AP-1 transcription factors, activities of which are decreased in SAMP6 as well as aged ICR mice. Therefore, diminished AP-1 activity and the resultant decline in IL-11 expression may play a role in impaired bone formation(More)
One-dimensional (1D) sliding of the tumor suppressor p53 along DNA is an essential dynamics required for its efficient search for the binding sites in the genome. To address how the search process of p53 is affected by the changes in the concentration of Mg(2+) and Ca(2+) after the cell damages, we investigated its sliding dynamics at different(More)
PURPOSE The small GTP-binding protein Rho and its best-characterized downstream effector Rho-associated serine-threonine protein kinase, ROCK, participate in actin cytoskeleton organization, and are linked to pathogenesis and progression of several human tumors. We investigated the roles of Rho and ROCK in bladder cancer. EXPERIMENTAL DESIGN Using Western(More)
The Rho family of GTPases are involved in actin cytoskeleton organization and associated with carcinogenesis and progression of human cancers. We investigated the roles of Rho family GTPases, prototypes RhoA, Rac1, and Cdc42, and the major downstream targets of RhoA, ROCK-I, and ROCK-II in testicular cancer. We quantified protein expression in paired tumor(More)
Thrombomodulin (TM) is an endothelial anticoagulant cofactor that promotes thrombin-mediated formation of activated protein C (APC). We have found that the N-terminal lectin-like domain (D1) of TM has unique antiinflammatory properties. TM, via D1, binds high-mobility group-B1 DNA-binding protein (HMGB1), a factor closely associated with necrotic cell(More)
IL-18 is an important regulator in both innate and acquired immune responses. The aberrant expression of IL-18 is associated with severe inflammatory conditions, such as autoimmune diseases and allergies. Thus, human antibodies with inhibitory activity on IL-18 signaling may be useful for therapeutic applications. We report here the first establishment of(More)
Molecular mechanism of mechanical stress-induced bone formation remains unclear. We demonstrate that mechanical unloading suppresses and reloading enhances Interleukin (IL)-11 gene expression in the hindlimb of mice in vivo. Mechanical stress to osteoblasts by fluid shear stress (FSS) in vitro rapidly and transiently enhances fosB gene transcription,(More)
We report a novel mutation of tau (L266V missense mutation in exon 9) which may cause a type of familial frontotemporal dementia. The brain of a patient showed Pick body-like inclusions and unique tau-positive, argyrophilic astrocytes with stout filaments and naked, round, or irregular argyrophilic inclusions with deposits of both three-repeat and(More)
BACKGROUND Some patients with hypertrophic cardiomyopathy (HCM) develop left ventricular (LV) wall thinning associated with LV dilatation and systolic dysfunction. Recently, matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs) were reported to be involved in ventricular remodeling, however, little is known about MMPs and TIMPs in patients(More)
