2. 1. Genomic Profiling, Mutations and Deranged Signaling in Esophageal Cancer and Hereditary Colorectal Cancer

   Author : Anna Isinger Ekstrand; Institutionen för immunteknologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal cancer; hereditary cancer; HNPCC; copy number analysis; CGH; gene expression; Wnt; PIK3CA; CHEK2; gastric cancer; colorectal cancer;

   Abstract : Esophageal cancer and colorectal cancer represents two major types of gastrointestinal tumors. Though refined surgery and introduction of novel chemotherapeutics have improved outcome, more than 2500 Swedes die from these diseases every year. Novel markers for early diagnosis, prognosis and treatment prediction are therefore needed. READ MORE

4. 2. Tumors associated with Hereditary Nonpolyposis Colorectal Cancer: Defective Mismatch Repair and Familial Risk of Cancer

   Author : Kajsa Ericson Lindquist; Bröstcancer-genetik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; cancerology; Cytologi; onkologi; cancer; Multiple Tumors; Hereditary Nonpolyposis Colorectal Cancer; Cytology; Cohort study; Population based; Familial Risk of Cancer; Immunohistochemistry; MSH2; MSH6; MLH1; Microsatellite Instability; Soft Tissue Sarcomas; Cancer of the Upper Urinary Tract; Cancer of the Small Intestine; Colorectal Cancer;

   Abstract : Inactivation of the DNA mismatch repair (MMR) system is a tumorigenic mechanism involved in 15-20% of tumor types such as colorectal and endometrial cancer and is specifically associated with the Hereditary Nonpolyposis Colorectal Cancer (HNPCC) syndrome. These MMR defective tumors are characterized by microsatellite instability (MSI), a phenomenon that reflects alterations in length of repeated sequences, and 90% of MSI tumors show loss of immunohistochemical expression for the MMR protein affected.

5. 3. Genetic epidemiology of prostate cancer

   Author : Fredrik Wiklund; Henrik Grönberg; Douglas Easton; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; prostate cancer; epidemiology; genetics; linkage analysis; genome-wide scan; Onkologi; Oncology; Onkologi; Oncology; onkologi;

   Abstract : Prostate cancer is a major health burden throughout the world, yet the etiology of prostate cancer is poorly understood. Evidence has accumulated supporting the existence of a hereditary form of this disease. READ MORE

6. 4. Multi-level characterization of host and pathogen in Helicobacter pylori-associated gastric carcinogenesis

   Author : Kaisa Thorell; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gastroenterology; cancer; infection; Helicobacter pylori; sequencing; genomics; transcriptomics; genomics;

   Abstract : Today, more than half of the world’s population is infected with Helicobacter pylori, and two to three per cent of these will develop gastric cancer associated with this infection. Gastric cancer is today the third largest cause of cancer mortality worldwide, with more than 700 000 deaths annually, a number that is expected to increase. H. READ MORE

7. 5. TGF-beta signaling in cancer

   Author : Erik Johansson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TGF-β; proliferation; cancer; tumor suppressor; diffuse-type gastric carcinoma; neuroblastoma; nuclear receptor TLX; cancer stem cell; angiogenesis; ABCG2; VHL; HIF2α; hypoxia; Smad3;

   Abstract : Transforming Growth Factor Beta (TGF-β) is a cytokine regulating a wide range of cellular processes such as proliferation, differentiation, and migration. At the early stages of cancer development TGF-β functions as a tumor suppressor, mainly due to its inhibitory effect on cellular growth, but during cancer progression, mutations in TGF-β signal components switches TGF-β into a promoter of cancer cell proliferation, survival and metastasis.
