16. Structure, Mechanism, and Regulation of Sodium/Proton Exchangers
Sammanfattning : Sodium/proton exchangers (NHEs) are secondary active transporters that are ubiquitously found in all kingdoms of life. They facilitate the exchange of protons for sodium ions or other inorganic ions across biological membranes, regulating pH, sodium levels, and osmotic pressure. LÄS MER
17. Gene regulation by nuclear hormone receptors in vivo
Sammanfattning : The nuclear hormone receptor superfamily contains 49 different members, including those for thyroid hormone, TR? and TR?. These receptors are ligand-modulated transcription factors that activate or repress gene activity. The TR? gene encodes two main splice variants, TR?1 and TR?2. LÄS MER
18. Regulation of eukaryotic cell physiology using organic bioelectronics
Sammanfattning : The field of organic bioelectronics deals with the implementation of conducting polymer science in biology and medicine. The purpose of this thesis was to develop organic bioelectronic devices for the regulation of eukaryotic cell physiology. LÄS MER
19. Regulation of glucagon secretion from pancreatic alpha cells
Sammanfattning : Glucagon secreted by pancreatic α-cells plays an important role in the regulation of blood glucose. In this thesis, different techniques such as electrophysiology, immunohistochemistry and hormone secretion assay were combined to explore the mechanisms by which glucagon secretion is regulated.

20. MYC and MNT in transcriptional regulation and chromatin dynamics
Sammanfattning : The MYC proto-oncogene regulates several cellular processes including cell cycle progression, proliferation, apoptosis and differentiation. In normal cells, MYC expression is induced upon cell cycle entry and is thereafter expressed at low levels during proliferation. LÄS MER
