Disease relevance of GSN

 

Psychiatry related information on GSN

  • However, we could detect no difference in the levels of expression of either ADF or cofilin in the hippocampal tissue from normal individuals and Alzheimer's disease patients [6].
 

High impact information on GSN

  • Adult T cell leukemia-derived factor (ADF), which we originally defined as an IL-2 receptor alpha-chain/Tac inducer produced by human T cell lymphotrophic virus-I (HTLV-I)-transformed T cells, has been identified as human TRX [7].
  • Extracellularly, TRX/ADF shows a cytoprotective activity against oxidative stress-induced apoptosis and a growth-promoting effect as an autocrine growth factor [7].
  • For example, TRX/ADF translocates from the cytosol into the nucleus by a variety of cellular stresses, to regulate the expression of various genes through the redox factor-1 (Ref-1)/APEX [7].
  • Intracellularly, TRX/ADF is involved in the regulation of protein-protein or protein-nucleic acid interactions through the reduction/oxidation of protein cysteine residues [7].
  • Using GSN polymorphisms, different haplotypes were found in the Danish and Czech families [1].
 

Chemical compound and disease context of GSN

 

Biological context of GSN

  • Linkage of a gene causing classic dystonia in a large non-Jewish kindred (DYT1) and in a group of Ashkenazi Jewish families, to the gelsolin (GSN) and arginino-succinate synthetase (ASS) loci on chromosome 9q32-34, respectively, was recently determined [13].
  • Age-dependent transcription factor (ADF) interacts with prostate-specific antigen (PSA) gene enhancer [14].
  • This suggests that ADF may play a role in the regulation of PSA gene expression [14].
  • Our data indicate that treatment of hippocampal neurons with fAbeta increases the level of Ser3-phosphorylated ADF/cofilin and Thr508-phosphorylated LIMK1 (P-LIMK1), accompanied by a dramatic remodeling of actin filaments, neuritic dystrophy, and neuronal cell death [15].
  • Thus, ADF and cofilin are coordinately regulated by posttranslational modification, but their expression is differentially regulated [16].
 

Anatomical context of GSN

  • These results suggest that LIMK2 functions downstream of the Rho-ROCK signalling pathway and plays a role in reorganization of actin filaments and membrane structures, by phosphorylating cofilin/ADF proteins [17].
  • The specific transcripts for beta-actin and actin-depolymerizing factor (ADF) were also present and non-uniformly distributed in axons, with an approximately hundredfold higher concentration in growth cones, branch points and axonal varicosities than in the axon shaft [18].
  • Myoblasts, transfected with a human gene encoding a beta-actin point mutation, down-regulate expression of actin depolymerizing factor (ADF) and its mRNA [16].
  • MATERIALS AND METHODS: The 2 human bladder cancer cell lines KU-7 and UMUC-2 were transduced with Ad-GSN in vitro [19].
  • In vivo KU-7 cells were introduced into the bladder of nude mice (day 0), followed by 3 injections into the urethra (days 2 to 4) with Ad-GSN or Ad-betagal (1 x 10 pfu) [19].
 

Associations of GSN with chemical compounds

  • We conclude that substitution of the uncharged Asn or Tyr for the acidic Asp at residue 187 creates a conformation that may be preferentially amyloidogenic for GSN [1].
  • Together, these data suggest that the weak androgenic effect of HF may be amplified by increasing the amount of GSN after androgen ablation treatment [2].
  • Cofilin/ADF, beryllium fluoride complex (BeFx), and phalloidin have opposing effects on actin filament structure and dynamics [20].
  • 1. Impulse activity in an identified serotonin-containing neuron (GSN) produces a slow excitatory synaptic response in another identified neuron, the A neuron [21].
  • 8. Cyproheptadine (reversibly), methergoline, mianserin and propranolol (all irreversibly) antagonised the response in the GSN [21].
  • When COS-1 cells transiently transfected with gelsolin cDNA were treated with etoposide or staurosporine, apoptosis-inducing agents, N-myristoylated tGelsolin was generated, as demonstrated by in vivo metabolic labeling [22].
 

Physical interactions of GSN

  • GSN interacts with AR DNA-binding domain and ligand-binding domain via its COOH-terminal domain [2].
 

Regulatory relationships of GSN

  • Functional analyses additionally demonstrate that GSN enhances AR activity in the presence of either androgen or HF [2].
 

Other interactions of GSN

  • The amino terminal sequence of this 12 kDa amyloid protein (ATEVPVSWESFNNGD) showed homology with gelsolin (or actin depolymerizing factor), a 93 kDa plasma protein [23].
  • TPSS is now or soon will be available in standard codes such as GAUSSIAN, TURBOMOLE, NWCHEM, ADF, WIEN, VASP, etc [24].
  • Brevin, like gelsolin from macrophages and villin from intestinal brush border, also appears capable of severing preformed actin filaments and disrupting filament networks as measured with a low-shear falling ball viscometer [25].
 

Analytical, diagnostic and therapeutic context of GSN

  • The expression of GSN is enhanced in LNCaP cells, LNCaP xenografts, and human prostate tumors after androgen depletion [2].
  • Immunoprecipitation using specific antibodies indicates that beta-actin, ADF and neurofilament protein (NF) are translated in axons independently of cell bodies [18].
  • We examined the activation of cofilin, an actin-depolymerizing factor, in lupeol-treated B16 2F2 cells by western blotting [26].
  • Here, we demonstrate by competitive electrophoretic mobility shift assay that ADF binds to a 19 bp sequence in PSA gene (-4372 to -4390) located within this enhancer region [14].
  • In this work, we genotyped 3 SNPs around the GSN locus in 493 sets of the Han Chinese trio sample using allele-specific PCR [27].
