Peroxisome proliferator-activated receptor-binding protein (PBP), also known as thyroid hormone receptor-associated protein 220/vitamin D receptor-interacting protein 205/mediator 1, an anchor for multisubunit mediator transcription complex, functions as a transcription coactivator for nuclear receptors. Disruption of the PBP gene results in embryonic(More)
Activated epidermal growth factor receptor (EGFR) has emerged as an important therapeutic target for a variety of solid tumors, particularly malignant gliomas. A recently discovered transmembrane glycoprotein, LRIG1, antagonizes the activity of epidermal growth factor receptor family receptor tyrosine kinases and acts as a negative feedback loop of EGFR and(More)
Since March 2001, a special class of recurrent neural networks termed the Zhang neural network (ZNN) has been proposed by Zhang and co-workers for solving online a rich repertoire of time-varying problems. By extending Zhang et al.’s design formula (or say, the ZNN design formula), a (new) variant of the ZNN design formula is proposed and investigated in(More)
Overexpression of epidermal growth factor receptor (EGFR, ErbB1) correlates with enhanced malignant potential of many human tumor types including glioblastoma multiforme. The significance of EGFR expression in meningiomas is, however, unclear. Reports regarding the other EGFR family members, ErbB2–4, in brain tumors are sparse. In this study, the expression(More)
Human LRIG1 (formerly LIG1), human LRIG2, and mouse Lrig1 (also known as Lig-1) encode integral membrane proteins. The human genes are located at chromosomes 3p14 and 1p13, which are regions frequently deleted in human cancers. We have searched for additional members of the LRIG family and by molecular cloning identified human LRIG3 and its mouse ortholog(More)
The LRIG1 gene (formerly LIG-1), recently cloned by us, displays structural similarities to the Drosophila Kek I gene. Kek I encodes a cell surface protein, Kekkon-1, which inhibits epidermal growth factor receptor-mediated signalling. We localized the LRIG1 gene to chromosome band 3p14.3, a region known to be deleted in various human cancers. In the(More)
The term laminopathies defines a group of genetic disorders caused by defects in the nuclear envelope, mostly the lamins. Lamins are the main constituents of the nuclear lamina, a filamentous meshwork associated with the inner nuclear membrane that provides mechanical stability and plays important roles in processes such as transcription, DNA replication(More)
Ciprofibrate, a potent peroxisome proliferator, induces pleiotropic responses in liver by activating peroxisome proliferator-activated receptor alpha (PPARalpha), a nuclear receptor. Transcriptional regulation by liganded nuclear receptors involves the participation of coregulators that form multiprotein complexes possibly to achieve cell and gene specific(More)
Arsenic trioxide (ATO) is an effective therapeutic agent for acute promyelocytic leukaemia (APL) (Evens et al, 2004). In APL, ATO induces differentiation at low concentrations, while inducing apoptosis at higher concentrations (Miller et al, 2002). In addition, ATO-induced apoptosis in APL is mediated through the mitochondrial apoptotic pathway, resulting(More)
The solvents n-pentane, methylene dichloride, ethyl ether and dodecylbenzenesulphonic acid sodium were used to regenerate exhausted activated carbon used in the process of treating coking wastewater, and the efficiency, ability, and optimum conditions of the different solvents on this regeneration were investigated. The results indicate that n-pentane could(More)
