Sammanfattning : MicroRNAs (miRNAs) contribute to cancer development and drug resistance via cellular biological processes, including metabolic pathways. Energy metabolism plays a significant role to maintain tumor proliferation in gastrointestinal (GI) cancers. However, the roles of miRNAs and energy metabolism in GI cancers are not fully understood.

2. Gastrointestinal stromal tumors. Pathogenetic mechanisms, phenotypic characterization and prognosis
Sammanfattning : Gastrointestinal stromal tumor (GIST), the most common non-epithelial neoplasm of the gastrointestinal tract, has historically been problematic both conceptually and clinically. Recently, GIST has been shown to share phenotypic features with the interstitial cells of Cajal (ICC), including the almost uniform expression of the tyrosine kinase receptor KIT. LÄS MER
Sammanfattning : The neuroendocrine (NE) tumours comprise a diversity of tumours which share commonproperties, e.g. the capacity to produce, store and release hormones. A prominent feature ofthe NE phenotype is the production of secretory granules with associated vescicle proteins,e. LÄS MER
Sammanfattning : The purpose of this study was to investigate how total body protein and its fraction of body weight (body protein fraction) change in cancer patients during different anti-tumor treatments, and to see if these changes have any clinical significance in the form of prognostic value or correlation with disease course and tumor response. In 84 patients, 28 with lung cancer, 24 with gastrointestinal tumors, 30 with breast cancer, 1 with non-Hodgkin lymphoma and 1 with kidney cancer, the total amount of body nitrogen was measured using an in vivo prompt gamma neutron activation technique.

Sammanfattning : The gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in the gastrointestinal tract (GI). Historically, these tumors were commonly mistaken for myogenic and neurogenic masses, and then eventually came to be recognized as a distinct type of soft-tissue sarcoma through ultrastructural findings and specific immunomarkers.
