Here, I address the function of the carboxy-terminal hydrophobic helix of the pro-apoptotic protein Bax. There has been considerable controversy as to whether this sequence is required for the targeting and insertion of Bax into the mitochondrial...
Copper--Physiological effect; Copper in the body; Heart--Hypertrophy
Previous studies have shown that copper (Cu) supplementation at physiologically relevant levels reverses cardiac myocyte hypertrophy induced by phenylephrine (PE), and that this effect was VEGF-dependent. Yet, the amount of VEGF in the media was...
Chapter I . Seven novel head-to-tail cyclic pentapeptides and pseudopentapeptides containing the arginine-glycine-aspartic acid (RGD) tripeptide motif were synthesized. All of the peptides were constructed using solid phase peptide synthesis....
The mechanisms by which estrogens regulate mitochondrial activity are not completely understood. Chronic treatment of ovariectomized rats with estradiol (E 2 ) increased the amount of Nuclear Respiratory Factor-1 (NRF-1) protein in cerebral blood...
Metastasis is a complex process requiring directed migration of metastatic cells to favorable microenvironments. Increased CXCR4 expression has been implicated in more invasive, aggressive and metastatic tumor phenotypes and poor patient survival...
The vast knowledge of nucleic acids is evolving and it is now known that DNA can adopt highly complex, heterogeneous structures. Among the most intriguing are the G-quadruplex structures, which are thought to play a pivotal role in cancer...
Algebra--Study and teaching (Elementary); Mathematical ability; Learning, Psychology of
The current study explored the impact that algebra knowledge in 1st and 2nd grade can have in growth and achievement in mathematics through 5th grade. Previous studies have shown the positive impact of teaching algebra in middle school (e.g. Smith,...
Gold nanoparticles (AuNPs) have attracted enormous attention in the field of nanotechnology for applications such as, immunoassay, drug delivery, contrast enhancement and tumor therapy. The typical range of gold nanoparticles varies from 1– 150...
Bcl-2 proteins are major regulators of cellular responses to various apoptotic stimuli. Among them, overexpression of the anti-apoptotic BcI-2 protein BcI-xL modulates organelle-specific apoptotic pathways. To understand the mechanisms by which...
Nanoparticles; Drug delivery devices; Gene therapy
The properties and broad applications of nano-magnetic colloids have generated much interest in recent years. Specially, Fe304 nanoparticles have attracted a great deal of attention since their magnetic properties can be used for hyperthermia...
Congenital stationary night blindness 1 (CSNBl) is a genetic disorder characterized in humans by night blindness, low visual acuity and myopia. CSNB 1 is caused by defects in genes that are involved in signaling between photoreceptors and...
c-Myc dysregulation is one of the most common abnormalities found in human cancer. MicroRNAs (miRNAs) are functionally intertwined with the c-Myc network as multiple miRNAs are regulated by c-Myc, while others directly suppress c-Myc expression. In...
Nanoparticles; Imaging systems in medicine; Imaging systems in biology
Gold nanoparticles (GNPs) have shown beneficial properties for biomedical use, e.g., their non-toxic nature and surface properties for easy modification. Upon receiving light, they generate a strong surface plasmon field, which can alter the...
This dissertation describes research focused on the synthesis, polymerization and
applications of cationic aminooxy lipids. An efficient and convenient method was
developed to stabilize liposomes using 'click chemistry'. The 'click...
Cancer accounts for nearly one-quarter of deaths in the United States, exceeded only by heart diseases. Despite the development of various strategies to treat cancer, it remains one of the most deadly diseases worldwide due to the limited effects...
The immune system is of profound importance for host survival due to its ability to clear many acquired diseases. In case of infections and cancer, disease arises due to under-performance of immune system. Whereas in autoimmunity and...
Night vision--Genetic aspects; Vision disorders--Genetic aspects
Mutations in the NYX gene, encoding the novel protein nyctalopin, cause human congenital stationary night blindness type 1 (CSNB1). CSNB1 is an X-linked recessive condition and is identified by a loss of the electroretinogram (ERG) b-wave while the...
Monoclonal antibodies directed toward tumor associated antigens are FDA approved anticancer reagents used commonly in the clinic. Administered antibodies initiate tumor cell death through several mechanisms. Improving immune mediated mechanisms,...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
Dimorphism is a highly conserved process in fungi in which a transition between a unicellular, yeast-like growth form and either a unicellular or multicellular, filamentous growth form occurs in response to several different environmental cues. The...
