21. Cell cycle regulatory genes in human astrocytic tumors
Sammanfattning : Cancer is a genetic disorder of somatic cells. Neoplastic transformation and malignant progression may be a consequence of accumulated multiple genetic changes in a cell. Astrocytic gliomas are the commonest brain tumors in humans. LÄS MER
22. Molecular studies of the insulin-like growth factor system in the brain : focus on growth, tumorigenesis and trauma
Sammanfattning : Insulin-like growth factor (IGF) 1 and -2 are synthesized by most tissues of the body and function as autocrine or paracrine agents in a tissue-specific manner. mRNA for IGF-1 and -2, as well as the IGF-binding proteins, are synthesized locally in various regions of the brain.

23. Alterations of cell cycle control genes in human astrocytomas
Sammanfattning : Cytogenetic analyses and molecular genetic studies have revealed a number of chromosomal regions deleted or amplified in astrocytic tumors, presumably harboring tumor suppressor genes and oncogenes involved in astrocytic oncogenesis. Astrocytomas represent the most common subgroup of primary intracranial tumors. LÄS MER
24. Neurotoxicity of methylmercury : analysis of molecular mechanisms and behavioral alterations
Sammanfattning : MethyImercury (MeHg) is a global pollutant that is toxic for the nervous system, especially during development. Contaminated fish is the main route of human exposure. Recent studies have indicated that neurological alterations in humans may occur even after exposure to fairly low levels of MeHg. LÄS MER
