Disease relevance of SOCS1

 

High impact information on SOCS1

  • The CIS family of proteins (also referred to as the SOCS or SSI family) has been implicated in the regulation of signal transduction by a variety of cytokines [8].
  • Moreover, the restoration of SOCS-1 suppressed both growth rate and anchorage-independent growth of cells in which SOCS-1 was methylation-silenced and JAK2 was constitutively activated [9].
  • We identified aberrant methylation in the CpG island of SOCS-1 that correlated with its transcription silencing in HCC cell lines [9].
  • This growth suppression was caused by apoptosis and was reproduced by AG490, a specific, chemical JAK2 inhibitor that reversed constitutive phosphorylation of STAT3 in SOCS-1 inactivated cells [9].
  • Reconstitution of the lymphoid lineage of JAK3-deficient mice with SOCS1-deficient stem cells recapitulates the lethality and T cell alterations [10].
 

Chemical compound and disease context of SOCS1

 

Biological context of SOCS1

 

Anatomical context of SOCS1

  • Furthermore, the inhibition of SOCS in the cardiac myocyte through adeno-associated virus-mediated (AAV-mediated) expression of a dominant-negative SOCS1 increased the myocyte resistance to the acute cardiac injury caused by enteroviral infection [16].
  • This suggests an important role for JAB/SOCS1/SSI-1 in regulating T-cell responses [17].
  • The effect of the interaction between FGFR3 and SOCS1 on receptor activity was investigated in a chondrocytic cell line overexpressing SOCS1 [14].
  • Expression of osteopontin (OPN), which is directly upregulated by FGF in chondrocytes, was stimulated by lower levels of FGF in cells expressing SOCS1 compared with parental cells [14].
  • Using reverse transcriptase (RT)-PCR and Western blot analysis we investigated the expression of SOCS1, SOCS2, and SOCS3 mRNA and protein, respectively, by human villous placenta, amnion and choriodecidua (n = 3-4) [18].
 

Associations of SOCS1 with chemical compounds

  • Our study demonstrates the substrate-specific E3 ubiquitin-ligase-like activity of SOCS1 for activated JAK2 and may provide a novel strategy for the suppression of oncogenic tyrosine kinases [12].
  • Treatment of these cell lines with the demethylating agent 5-aza-2'-deoxycytidine (DAC) up-regulated SOCS-1 expression [19].
  • Mutation of receptor tyrosines 950, 1250, 1251, and 1316 to phenylalanine or deletion of the COOH-terminal 93 amino acids did not result in decreased interaction of the receptor with hSOCS-2 protein. hSOCS-1 protein also interacted strongly with IGF-IR in the two-hybrid assay [20].
  • In contrast, titanium inhibition of interferon-gamma signaling is not dependent on mitogen-activated protein kinase activation and is accompanied by only modest induction of the interferon-gamma inhibitor SOCS1 [21].
  • In addition, SOCS1, a negative regulator of IFNgamma signaling and which is degraded by the proteasome, was stabilized by ethanol treatment, presumably because of inhibited proteasome activity [22].
