Evaluation of Phosphatidylserine-Binding Peptides Radiolabeled with Fluorine 18 for in vivo Imaging of ApoptosisDownload
We currently do not have a clinical method to directly assess apoptosis induced by cancer therapies. Phosphatidylserine (PS) is an attractive target for imaging apoptosis since it is on the exterior of the apoptotic cells and PS externalization is an early marker of apoptosis. PS-binding peptides...
Approximately 70% of patients infected with hepatitis C virus (HCV) develop chronic infection, which has been reported to be due to impaired specific T cell responses. Myeloid dendritic cells (mDCs) are potent antigen-presenting cells that regulate T cell responses, however their role during...
During infection, the host cell environment must be altered to accommodate viral replication. These alterations include hijacking cellular membranes as well as other components to form viral replication compartments and attenuating the host defenses to prevent virus detection and elimination....
From the basic understanding of N-myristoylation during apoptosis to a potential personalized medical treatment of B cell lymphomasDownload
Myristoylation is a type of fatty acylation that involves the irreversible attachment of myristate (C14) to an amino-terminal glycine of a protein via an amide bond by N-myristoyltransferase (NMT). The two human N-myristoyltransferases (NMT1 and NMT2) typically play a pro-survival role in cells...
Deregulated TNF signaling with elevated or decreased levels of TNF-induced apoptosis causes numerous inflammatory and cancerous diseases. Thus, there is a clear need to identify cellular proteins that regulate cell fate in the presence of TNF. RNA interference technology provides an excellent...
Insights into the role of CTP:phosphocholine cytidylyltransferase-alpha in hepatic lipid metabolism and cellular integrityDownload
Lower levels of hepatic phosphatidylcholine (PC) are suggested to play a role in the pathogenesis of non-alcoholic steatohepatitis (NASH). Mice lacking hepatic CTP:phosphocholine cytidylyltransferase-α (LCTα-/-), the regulatory enzyme in the CDP-choline pathway for PC biosynthesis, were fed a...
Interactions between Amyloid Precursor Protein and Prion Protein Impact Cell Adhesion and Apoptosis in the Developing ZebrafishDownload
We report here that knockdown of either amyloid precursor protein (APP) or prion protein (PrP) in the zebrafish produces an overt dose-dependent phenotype characterized by systemic morphological defects and CNS cell death. We report findings that the zebrafish PrP-1 gene genetically interacts...
The growth and development of an organ is a multi-step process. It involves initial specification of the progenitor cells to become a particular cell type, proliferation of those cells for organ growth, and organization of the cells into a final functional tissue. The growth and development of...
The activation of caspases is an important step not only in apoptosis induction, but in cellular processes such as proliferation, differentiation, and the immune response. Here, we show that the AP-1 family transcription factor JunB is cleaved and dephosphorylated in a caspase-dependent manner in...
Apoptosis, an evolutionarily conserved cell death programme, is a potent barrier against virus infection. Central to this process are mitochondria, which harbour cytochrome c and other apoptosis-inducing factors. Once released, these factors activate a caspase cascade that culminates in cell...
