Netrins are prototypical axon guidance cues whose attractive signaling requires the small GTPase Rac1. It remains unclear how Rac1 is regulated in the netrin pathway. DOCK180 is a member of a new family of guanine nucleotide exchange factors for Rho GTPases. Here we provide evidence implicating DOCK180 in netrin signal transduction. Netrin promoted the(More)
Netrins are an important family of axon guidance cues. Here, we report that netrin-1 induces tyrosine phosphorylation of p130(CAS) (Crk-associated substrate). Our biochemical studies indicate that p130(CAS) is downstream of the Src family kinases and upstream of the small GTPase Rac1 and Cdc42. Inhibition of p130(CAS) signaling blocks both the neurite(More)
Hepatocellular carcinoma (HCC) is a highly malignant tumor, and chronic infection with hepatitis B virus is one of its major risk factors. To identify the proteins involved in HCC carcinogenesis, we used two-dimensional fluorescence DIGE to study the differentially expressed proteins in tumor and adjacent nontumor tissue samples. Samples from 12 hepatitis B(More)
Hereditary nonsyndromic hearing loss is highly heterogeneous and most patients with a presumed genetic etiology lack a specific diagnosis. It has been estimated that several hundred genes may be associated with this sensory deficit in humans. Here, we identified compound heterozygous mutations in the TMC1 gene as the cause of recessively inherited(More)
The objective of this study was to investigate the single nucleotide polymorphisms (SNPs) within bovine binding lectin-liver (A) gene (MBL1) and to explore its correlation analysis with milk somatic cell score (SCS) which reflects mastitis resistance in cattle. Through polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), created(More)
This study was designed to investigate the candidate single nucleotide polymorphisms (SNPs) in the exon’s region of bovine diacylglycerol O-acyltransferase (DGAT1) gene using bioinformatics and experimental methods. A total of 17 SNPs were screened from public data resources and DNA sequencing. Three SNPs (c.572A>G, c.1241C>T and c.1416T>G) of these(More)
Each year in China, 30,000 babies are born with congenital hearing impairment. However, the molecular etiology of hearing impairment in the Yunnan Province population where more than 52 minorities live has not been thoroughly investigated. To provide appropriate genetic testing and counseling to these families, we investigated the molecular etiology of(More)
Using the medium voltage (MV) distribution line as a communication medium of the distribution automation and public communication is a cost-effective, advantage and effective way. The ring, radial and mixed lines distribution network have made the grade on power supply networks in urban areas. This paper presents the typical designs of power line(More)
Using the Medium Voltage(MV) distribution line as a communication medium of the distribution automation and public communication could also be a cost-effective, advantageous and effective way compared to other systems because it is an existing infrastructure. In order to investigate MV PLC's signal leakage interference & transmission characteristics at(More)
Progranulin (PGRN) has recently emerged as a key player in a subset of frontotemporal dementias (FTD). Numerous mutations in the progranulin gene have been identified in patients with familial or sporadic frontotemporal lobar degeneration (FTLD). In order to understand the molecular mechanisms by which PGRN deficiency leads to FTLD, we examined activity of(More)
