Project description:Two major genetic pathways leading to colorectal carcinoma can well be distinguished; the ‘suppressor pathway’, which is characterized by inactivation of tumor-suppressor genes and the ‘mutator pathway’, which is characterized by microsatellite instability. The purpose of this study is to explore a third putative pathway; microsatellite and chromosome stable colorectal cancer where an alternative cancer-causative mechanism might play a role.

Project description:Colorectal carcinoma is a heterogeneous disease that is caused by the interaction of genetic and environmental factors. colorectal carcinoma encompasses a complex disease with different molecular pathways and biological characteristics arising from a multi-step process that implicates several genetic and epigenetic events . The multi-step genetic model involves the loss of function of tumor suppressor genes, such as adenomatous polyposis coli (APC), Telomeres could be a promising marker due to the fact that their lengths change in the colorectal polyp-carcinoma sequence . Moreover, telomere length (TL) is altered in blood cells in patients with colorectal carcinoma
* These findings could suggest that changes in TL may take place before the development of the tumor .
The two main forms of inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn’s disease (CD) are characterized by chronic intestinal inflammation and risk of progression to colon cancer. One proposed cause of the latter characteristic is chromosome instability, since the rearrangement of genetic material can lead to activation of oncogenes, loss of tumor suppressor genes and other changes that lead to uncontrolled cell growth. Chromosome instability is particularly associated with UC and has been observed in colon epithelial cells and peripheral blood mononuclear cell. Since genomic instability in peripheral blood mononuclear cells (PBMCs) has been used as a biomarker for global cancer risk in a number of diseases, the latter observation suggests the possibility of a chromosome instability syndrome in UC that could affect all tissues. One possible cause of chromosome instability is telomere dysfunction .

Project description:We report the the identification of chrosomal regions bound by the Wilms' tumor suppressor gene WT1 during embryonic mouse kidney development. Two indepednent ChIP-Seq experiments on microdissected E18.5 developing mouse kidneys were carried out using either WT1-specific or IgG-antibodies as a negative control.

Project description:nc886 is a 101 nucleotides long non-coding RNA that is also known as a precursor microRNA or a vault RNA. nc886 has been suggested to be a tumor suppressor, mainly inferred by its expression pattern as well as its genomic location at human chromosome 5q31, a locus for a tumor suppressor gene(s).

Project description:The SLC22A18 gene, which encodes an orphan transporter, is located at the 11p15.5 imprinted region, an important tumor-suppressor gene region. However, the role of SLC22A18 in tumor suppression remains unclear. Here, we investigated the involvement of SLC22A18 in cell growth, invasion and drug resistance of MCF7 human breast cancer cell line. Western blot analysis indicated that SLC22A18 is predominantly expressed at intracellular organelle membranes. Quantitative proteomics showed that knockdown of SLC22A18 significantly altered the expression of 578 (31.0%) out of 1867 proteins identified, including proteins related to malignancy and poor prognosis of breast cancer.
