Investigation of SNX3 in colon cancer

Cingöz, Harun
Sorting Nexin 3 (SNX3) is part of the retromer complex that recycles cargo receptors back to plasma membrane or to Trans Golgi Network. WNT ligand carrier protein Wntless (WLS) is a known SNX3 cargo protein. Our earlier data suggested over expression of SNX3 in colon cancer cells. Considering its importance in receptor recycling, we hypothesized SNX3 to be a potential modulator of cancer related receptors. To begin understanding the role of SNX3, we developed RNAi models of SNX3 in SW480 colon cancer cells and investigated biochemical and phenotypical outcomes of SNX3 knock down. Here we present evidence that SNX3 might regulate several receptors important in colon cancers and decreased SNX3 expression alters motility and migration of colon cancer cells by downregulating important signaling pathways with implications in epithelial to mesenchymal transition.


Investigation of telomerase activity and gene expression in colorectal cancer
İzgi, Ahu; Gündüz, Ufuk; Department of Biology (2012)
Human telomerase is a reverse transcriptase which synthesizes telomeric repeat sequences at the ends of chromosomes. The telomerase enzyme has two essential subunits to be functional which are called telomerase reverse transcriptase (hTERT) and human telomerase RNA (hTR). Telomerase uses its RNA subunit as a template for the addition of hexameric repeats at the ends of chromosomes. The activity of telomerase has been detected in immortal cells but not in most normal somatic cells. Therefore, its activity co...
Analysis of 3'UTR shortening events in breast cancer
Baloğlu, Onur; Can, Tolga; Department of Bioinformatics (2013)
Cancer is the collective term used to describe a diverse group of diseases that share certain hallmarks, which in turn enables the affected cells to sustain an uncontrolled cell growth. Despite the increasing efforts and advances in cancer therapies, cancers are still responsible for approximately 10% of all the deaths worldwide. Furthermore, the increase in the average human lifespan will further contribute to the cancer incidences. This brings the necessity to focus our efforts on early detection and effe...
Comparative phosphoproteomic analysis reveals signaling networks regulating monopolar and bipolar cytokinesis.
KARAYEL, Ö; ŞANAL, E; GIESE, SH; Üretmen, Kagıalı; POLAT, AN; HU, CK; RENARD, BY; Tunçbağ, Nurcan; ÖZLÜ, N (2018-02-02)
The successful completion of cytokinesis requires the coordinated activities of diverse cellular components including membranes, cytoskeletal elements and chromosomes that together form partly redundant pathways, depending on the cell type. The biochemical analysis of this process is challenging due to its dynamic and rapid nature. Here, we systematically compared monopolar and bipolar cytokinesis and demonstrated that monopolar cytokinesis is a good surrogate for cytokinesis and it is a well-suited system ...
Investigating the malleability of RNA aptamers
İlgü, Müslüm; Lamm, Monica H.; Nilsen-Hamilton, Marit (Elsevier BV, 2013-09-15)
Aptamers are short, single-stranded nucleic acids with structures that frequently change upon ligand binding and are sensitive to the ionic environment. To achieve facile application of aptamers in controlling cellular activities, a better understanding is needed of aptamer ligand binding parameters, structures, intramolecular mobilities and how these structures adapt to different ionic environments with consequent effects on their ligand binding characteristics. Here we discuss the integration of biochemic...
Experimental Generation of Carcinoma-Associated Fibroblasts (CAFs) from Human Mammary Fibroblasts
Polanska, Urszula M.; Acar, Ahmet; Orimo, Akira (2011-10-01)
Carcinomas are complex tissues comprised of neoplastic cells and a non-cancerous compartment referred to as the 'stroma'. The stroma consists of extracellular matrix (ECM) and a variety of mesenchymal cells, including fibroblasts, myofibroblasts, endothelial cells, pericytes and leukocytes(1-3).
