Disease relevance of CIC

 

Psychiatry related information on CIC

 

High impact information on CIC

  • In contrast to most known ion channels, which have single pores, a chloride channel belonging to the CIC family (Torpedo CIC-0) has functional features that suggest that it has a unique 'double-barrelled' architecture in which each of two subunits forms an independent pore [7].
  • Although the CIC channels expressed in Xenopus oocytes have been characterized, their channel properties are still poorly understood [8].
  • Indeed, CIC-DUX4 directly binds the ERM promoter by recognizing a novel target sequence and significantly up-regulates its expression [3].
  • Sequence analysis of 780 bp of ORF from the clones suggests that the identified gene, termed hCIC-K2, encodes a new member of the CIC family of voltage-gated chloride channels [9].
  • Using a specific antibody raised against a 15-amino acid peptide from the CIC sequence, we concluded that CIC and P25 are identical entities, and hence that P25 belongs to the MIP family [10].
 

Chemical compound and disease context of CIC

 

Biological context of CIC

  • Alternative splicing of ClC-6 (a member of the CIC chloride-channel family) transcripts generates three truncated isoforms one of which, ClC-6c, is kidney-specific [15].
  • A new cold-regulated (COR) gene, msa CIC, was isolated by differential screening of a cDNA library from cold-acclimated crowns of alfalfa (Medicago sativa L. cv. Apica) [16].
  • The DNA sequence analysis of a full-length cDNA clone revealed that msa CIC encodes for a putative protein (MSACIC) of 166 amino acids with distinct proline-rich and hydrophobic domains [16].
  • The concentration of CIC and the light dose that correspond to ca 50% level of phototoxicity induce predominantly an apoptotic-type of cell death, whereas the conditions providing 100% level of phototoxicity induced necrosis [17].
  • No significant relationship among erythrocyte CR1 molecules, erythrocyte surface-associated immunoglobulins, CIC, and HLA phenotype was observed in any patient group [18].
 

Anatomical context of CIC

 

Associations of CIC with chemical compounds

  • Although PEG precipitates were enriched for high molecular weight IgA and IgG (presumably bound within CIC), significant amounts of IgM, unbound IgG and C3 were also present [22].
  • Compounds of more recent research are MERCK 3535 (aminopropionic acid ethylester), p-menthane-3,8 diol, CIC 4 (a lacton) and the piperidine derivatives AI3-37220 and Bayrepel (Icaridin) [23].
  • In addition, the CIC cholesterol level diagnoses extracoronary atherosclerosis with high accuracy [14].
  • Even though vitamin A supplementation in malnourished children did not significantly alter the duration of diarrhea, a beneficial effect was observed in children who had CIC state 3 and above in association with malnutrition (p = 0.025) [24].
  • The determination of CIC is carried out by means of precipitation with 3.5% PEG and a posterior determination of C4 of the precipitates as well as optical density [25].
 

Other interactions of CIC

  • This study clarifies the function of CIC and its role in tumorigenesis, as well as the importance of the PEA3 subclass of ETS family proteins in the development of EFTs arising through mechanisms different from those involving EWS-ETS chimeras [3].
  • In a parallel study increased CIC and anti-IgG Ab levels were found in most of the 81 patients with seropositive or seronegative rheumatoid arthritis [26].
  • The levels of L-CR1 transcription correlated negatively with the levels of CIC and anti dsDNA antibodies and positively with serum C3 levels [27].
  • The influence of therapeutic regimens on elevated CIC level in the CSF was insignificant [28].
  • Obstructive complications were defined as increased PVR (greater than 100 cc), or the need for CIC, prolonged Foley catheter drainage or urethrolysis [29].
 

Analytical, diagnostic and therapeutic context of CIC

  • RT-PCR and in situ hybridization verified the expression of CIC in tumor cells, although the level of expression varied between different medulloblastoma subtypes [1].
  • CIC have played a major role in cancer-associated immunosuppression [19].
  • In these patients, there was a good correlation between the level of IgM-RF and the amount of IgE detected in the CIC by the RIA method (r = 0.87) whereas the RF-interference free ELISA method showed no correlation between these two parameters (r = 0.06) [30].
  • Analysis of sera by HPLC revealed that both monomeric and higher molecular forms of IgA antibodies were present, the latter being coincident with the peak of IgA CIC [31].
  • The incidence of Epstein-Barr virus (EBV) viraemia and lymphoproliferative disease (LPD) was studied in a consecutive cohort of 128 paediatric patients undergoing stem cell transplantation (SCT) with reduced-intensity conditioning (RIC; n = 65) or conventional-intensity conditioning (CIC; n = 68) [32].
