MSR1, ASCC1, and CTHRC1 (Nomenclature of Genes in Esophageal cancer)

CTHRC1" is a  protein that has the ability to inhibit collagen matrix synthesis.
  Expression of Cthrc1 is increased in fibroblasts and chondrocytic cells in response to TGF-beta family members including BMP4, BMP2 and TGF-beta. Cthrc1 is also upregulated during tumorigenesis and metastasis;
CTHRC1 has been linked to major signaling pathways such as Wnt and TGF-beta. The ability of CTHRC1 to inhibit TGF-beta signaling via a reduction in Smad 2/Smad 3  (is to be noted!)
Location 8q22.3. (Leclair at al )

Once again this comment suggests that stimulation of growth factor induced secondarily by NF-kB /c-JUn amplification leads to secondary amplification which in this case happens to  this gene.  This gene comes into play in vascular remodeling suggesting invasiveness of the cancer.  This is the stuff used by neurone to find their way down their passage. If it is expressed it marks cellular invasiveness.  Please pay marked attention to the pathway with witch it is identified, a pathway we believe is very important but neglected. The Wnt pathway.  This is the metastasis pathways, it correlates with metastatic disease and is the stuff you find in triple negative Breast cancer!   
Suppression of Smad2 could prevent cancer induced by Irritations?  and may be secondary cancers?

2.ASCC1.
This gene encodes a subunit of the activating signal cointegrator 1 (ASC-1) complex. The ASC-1 complex is a transcriptional coactivator that plays an important role in gene transactivation by multiple transcription factors including activating protein 1 (AP-1), nuclear factor kappa-B (NF-kB) and serum response factor (SRF). The encoded protein contains an N-terminal KH-type RNA-binding motif which is required for AP-1 transactivation by the ASC-1 complex. Mutations in this gene are associated with Barrett esophagus and esophageal adenocarcinoma. Alternatively spliced transcripts encoding multiple isoforms have been observed for this gene.

Activating signal cointegrator 1 complex subunit 1 (ASCC1) is a subunit of the activating signal cointegrator 1 (ASC-1) complex. The ASC-1 complex is a transcriptional coactivator that plays an important role in gene transactivation by multiple transcription factors including activating protein 1 (AP-1), nuclear factor kappa-B (NF-kB) and serum response factor (SRF). ASCC1 contains an N-terminal KH-type RNA-binding motif which is required for AP-1 transactivation by the ASC-1 complex. Mutations in the ASCC1 gene are associated with Barrett esophagus and esophageal adenocarcinoma [taken from NCBI Entrez Gene (Gene ID: 51008)].

Alternative names for ASCC1 Antibody include activating signal cointegrator 1 complex subunit 1 antibody, ASC-1 complex subunit p50 antibody, Trip4 complex subunit p50 antibody, p50 antibody, CGI-18 antibody, ASC1p50 antibody.

I refuse to comment on this one because it is so obvious, this is at the core of pathogenesis where chronic stimuli act through the NF-kB and C-JUN to induce growth factors which eventually stimulate a secondary amplification that leads to the pathogenesis of cancer, additional mutations such as that occurring in CTHRC1 will complete the dance.  This ASCC1 appears to be a CBF like molecular complex driving this transformation and therefore it is a valid target for therapy.
