Myelin inhibitors of axonal regeneration, like Nogo and MAG, block regrowth after injury to the adult CNS. While a GPI-linked receptor for Nogo (NgR) has been identified, MAG's receptor is unknown. We show that MAG inhibits regeneration by interaction with NgR. Binding of and inhibition by MAG are lost if neuronal GPI-linked proteins are cleaved. Binding of(More)
The ciliate Tetrahymena thermophila is a model organism for molecular and cellular biology. Like other ciliates, this species has separate germline and soma functions that are embodied by distinct nuclei within a single cell. The germline-like micronucleus (MIC) has its genome held in reserve for sexual reproduction. The soma-like macronucleus (MAC), which(More)
BRCA1 and BRCA2 are often mutated in familial breast and ovarian cancer. Both tumor suppressors play key roles in the DNA-damage response. However, it remains unclear whether these two tumor suppressor function together in the same DNA-damage response pathway. Here, we show that BRCA1 associates with BRCA2 through PALB2/FANCN, a major binding partner of(More)
Inherited mutations in human PALB2 are associated with a predisposition to breast and pancreatic cancers. PALB2's tumor-suppressing effect is thought to be based on its ability to facilitate BRCA2's function in homologous recombination. However, the biochemical properties of PALB2 are unknown. Here we show that human PALB2 binds DNA, preferentially D-loop(More)
Atherogenesis is a complex process involving inflammation. S100A8 and S100A9, the Ca2+-binding neutrophil cytosolic proteins, are associated with innate immunity and regulate processes leading to leukocyte adhesion and transmigration. In neutrophils and monocytes the S100A8-S100A9 complex regulates phosphorylation, NADPH-oxidase activity, and fatty acid(More)
Evaluating biliary excretion, a major elimination pathway for many compounds, is important in drug discovery. The bile duct-cannulated (BDC) rat model is commonly used to determine the percentage of dose excreted as intact parent into bile. However, a study using BDC rats is time-consuming and cost-ineffective. The present report describes a computational(More)
AIM To determine the most effective treatment and long-term outcome of patients with stage IB carcinoma of the cervix. METHODS From January 1999 to December 2001, 106 women with cervical cancer stage IB received neoadjuvant chemotherapy (n = 52) or primary surgery (n = 54). These were randomly assigned. Clinical effects and pathological changes were(More)
Ichthyophthirius multifiliis, commonly known as Ich, is a highly pathogenic ciliate responsible for 'white spot', a disease causing significant economic losses to the global aquaculture industry. Options for disease control are extremely limited, and Ich's obligate parasitic lifestyle makes experimental studies challenging. Unlike most well-studied(More)
Software as a Service (SaaS) is an important technology innovation as well as a business model innovation to bring new opportunities to Small and Medium Enterprises (SME). There are different SaaS provisioning methods, depending on the customer profile, the cost of the required resources, and the price that customers are willing to pay. The core technology(More)
A transgenic Bt cotton (Sukang-103) and its non-Bt cotton counterpart (Sumian-12) were investigated to evaluate the potential risk of transgenes on the soil ecosystem. The activities of urease, phosphatase, dehydrogenase, phenol oxidase, and protease in cotton rhizosphere were assayed during the vegetative, reproductive, and senescing stages of cotton(More)
