1. 1. Prognostic role of the tumour microenvironment in esophago-gastric, pancreatic and periampullary adenocarcinoma: B cells and beyond

   Författare :Richard Fristedt; Tumörmikromiljö; []
   Nyckelord :Polymeric immunoglobulin receptor; B cells; Plasma cells; Esophageal adenocarcinoma; gastric adenocarcinoma; Pancreatic ductal adenocarcinoma; Periampullary adenocarcinoma; Prognosis and survival; Immune system;

   Sammanfattning : Cancer development depends on cells aquiring a skillset of limitless growth and finally invasive properties to allow for metastasis, as summarised by the six hallmarks of cancer. Recently four more hallmarks have been added: genomic instability, deregulating cellular metabolism, tumour-promoting inflammation and avoiding immune destruction. LÄS MER

3. 2. Protein tyrosine kinases in insulin producing cells : Expression and putative importance for beta-cell function

   Författare :Charlotte Öberg-Welsh; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinase; insulin producing cells; fetal development; VEGF; Src-family; Bsk; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : Protein tyrosine kinases are of importance for cell replication and differentiation in manysystems. The mechanisms controlling the replication and differentiation of insulin producingcells are unknown. LÄS MER

4. 3. INITIATION OF EXPERIMENTAL ACUTE PANCREATITIS AND MODULATION OF INFLAMMATORY RESPONSE

   Författare :Jakob B Axelsson; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear factor kappa B; neutrophils; monocytes; acute pancreatitis; ductal cells; active site-inhibited factor seven; heparan sulfate; lipopolysaccharide; innate immune response;

   Sammanfattning : Heparan sulfate (HS), a substance common in the extracellular matrix on epithelial cells is present in the pancreas, lining the duct lumen. During pathological conditions, we propose that it can be shed from the ECM and bind to receptors on the cell surface, thus triggering an inflammatory response, which if excessive can cause acute pancreatitis (AP).

5. 4. Repurposing digitoxin in the treatment of pancreatic ductal adenocarcinoma : genotypic and phenotypic features as biomarkers for digitoxin sensitivity in vitro

   Författare :Heléne Lindholm; Katarina Ejeskär; Ferenc Szekeres; Maria Faresjö; Sofie Mohlin; Högskolan i Skövde; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic ductal adenocarcinoma; Na K -ATPase; digitoxin; cardiac glycoside; metabolomics; choline; Translationell medicin TRIM; Translational Medicine TRIM;

   Sammanfattning : The incidence of pancreatic ductal adenocarcinoma (PDAC) is increasing worldwide. The dismal prognosis and lack of effective treatments urges for increased research efforts in developing new treatment regimens. Since the development of new cancer treatments are expensive and time consuming, repurposing drugs is preferable when possible. LÄS MER

7. 5. Transcriptional regulation in neuroblastoma cells under normoxic and hypoxic conditions

   Författare :Annika Jögi; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; cancerology; Cytologi; onkologi; cancer; Cytology; HIF-2; HIF-1; hypoxia; Id; HES-1; bHLH; Neuroblastoma; neuronal differentiation;

   Sammanfattning : The childhood malignancy neuroblastoma develops from early cells of the sympathetic nervous system (SNS), and the tumors often produce catecholamines. Neuroblastoma cells retain several characteristics of immature sympathetic cells including the expression of a number of transcription factors normally expressed during embryogenesis. LÄS MER
