Cancer cells can obtain their ability to invade and metastasise by undergoing epithelial-to-mesenchymal transition (EMT). Exploiting this mechanism of cellular plasticity, malignant cells can remodel their actin cytoskeleton and down-regulate proteins needed for cell-cell contacts. The mechanisms of cytoskeletal reorganisation resulting in mesenchymal(More)
BACKGROUND Diaphanous-related formins govern actin-based processes involved in many cellular functions, such as cell movement and invasion. Possible connections to developmental processes and cellular changes associated with malignant phenotype make them interesting study targets. In spite of this, very little is known of the tissue distribution and(More)
Neuropeptide Y (NPY) is universally expressed in many different neuronal and non-neuronal cells. Human NPY gene has two in-frame kozak sequences and thus, has potentially two translation initiation sites producing two NPY peptides with different molecular weights. In the present study, the intracellular location of NPY was studied in endothelial cells(More)
Preoperative diagnostics of ovarian neoplasms rely on ultrasound imaging and the serum biomarkers CA125 and HE4. However, these markers may be elevated in non-neoplastic conditions and may fail to identify most non-serous epithelial cancer subtypes. The objective of this study was to identify histotype-specific serum biomarkers for mucinous ovarian cancer.(More)
OBJECTIVE There is clear evidence of a genetic component in major depression, and several studies indicate that neuropeptide Y (NPY) could play an important role in the pathophysiology of the disease. A well-known polymorphism encoding the substitution of leucine to proline in the signal peptide sequence of NPY (Leu7Pro variation) was previously found to(More)
Preproneuropeptide Y is a precursor peptide to mature neuropeptide Y (NPY), which is a universally expressed peptide in the central and peripheral nervous system. NPY is normally routed to endoplasmic reticulum and secretory vesicles in cells, which secrete NPY. In our previous studies, we found a functional Leucine7 to Proline7 (L7P) polymorphism in the(More)
