Rnai Nanotechnology: A Platform For Sirna Screening And Cancer Gene Therapy, Mayurbhai Ravikant Patel
Seton Hall University Dissertations and Theses (ETDs)
Over the past two decades, advances in RNA structural biology have improved our understanding of the structures and folding properties of naturally occurring RNAs. RNA sequences and structures participate in many specific biological functions, such as those performed by messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), micro RNA (miRNA), short-interfering RNA (siRNA), small nuclear RNA (snRNA) and many others. The noncoding RNAs, such as siRNA, do not express proteins but have been utilized in a wide range of applications, including RNA interference (RNAi) and the regulation of mRNA expression. These important biological functions have been implemented in gene …

Poly (ADP-ribose) polymerase inhibitors (PARPi) emerge as potential targeting drugs for BRCA-deficient cancers including triple negative breast cancer (TNBC). However, it has been reported that a subgroup of patients even with BRCA mutation fails to respond to PARPi in multiple clinical trials. In this study, we identified c-Met, a tyrosine kinase, phosphorylates PARP1 at Y907 and that the phosphorylation increases PARP1 activity, thereby rendering cancer cells resistant to PARPi. The combination of c-Met inhibitors (METi) and PARPi has a synergistic effect for c-Met overexpressed TNBC in vitro and in vivo. In addition to c-Met, through functional analysis, we found …

Intimin Likely Used To Cause Disease During Competition With Commensal Escherichia Coli, Dominique J. Richburg
Senior Honors Theses
The intimin gene in the Locus of Enterocyte Effacement (LEE) island of pathogenicity is the primary attachment mechanism in Citrobacter rodentium. Intimin is a bacterial adhesin (protein) that attaches to obtain a niche/nutrient and thrive within the intestine. Intimin was deleted within C. rodentium to study colonization and pathogenesis in the murine intestine. Additionally, C. rodentium is an attaching/effacing pathogen, and a useful murine model in understanding Enterohemorrhagic Escherichia coli (EHEC) infection in humans. E. coli and C. rodentium cause gastroenteritis in humans and mice, respectively. C. rodentium is a murine pathogen commonly used to model gastrointestinal disease because …
Clinical Light Exposure, Photoreceptor Degeneration, And Ap-1 Activation: A Cell Death Or Cell Survival Signal In The Rhodopsin Mutant Retina?, Danian Gu, William Beltran, Zexiao Li, Gregory M. Acland, Gustavo D. Aguirre

PURPOSE. The T4R RHO mutant dog retina shows retinal degeneration with exposures to light comparable to those used in clinical eye examinations of patients. To define the molecular mechanisms of the degeneration, AP-1 DNA-binding activity, composition, posttranslational modification of the protein complex, and modulation of ERK/MAPK signaling pathways were examined in light-exposed mutant retinas. METHODS. Dark-adapted retinas were exposed to short-duration light flashes from a retinal camera used clinically for retinal photography and were collected at different time points after exposure. Electrophoretic mobility shift assay (EMSA), supershift EMSA, Western blot analysis, and immunocytochemistry were used to examine AP-1 signaling. RESULTS. …

PURPOSE. Canine multifocal retinopathy (cmr) is an autosomal recessive disorder of multiple dog breeds. The disease shares a number of clinical and pathologic similarities with Best macular dystrophy (BMD), and cmr is proposed as a new large animal model for Best disease. METHODS. cmr was characterized by ophthalmoscopy and histopathology and compared with BMD-affected patients. BEST1 (alias VMD2), the bestrophin gene causally associated with BMD, was evaluated in the dog. Canine ortholog cDNA sequence was cloned and verified using RPE/choroid 5′- and 3′-RACE. Expression of the canine gene transcripts and protein was analyzed by Northern and Western blotting and immunocytochemistry. …

Considerable clinical and molecular variations have been known in retinal blinding diseases in man and also in dogs. Different forms of retinal diseases occur in specific breed(s) caused by mutations segregating within each isolated breeding population. While molecular studies to find genes and mutations underlying retinal diseases in dogs have benefited largely from the phenotypic and genetic uniformity within a breed, within- and across-breed variations have often played a key role in elucidating the molecular basis. The increasing knowledge of phenotypic, allelic, and genetic heterogeneities in canine retinal degeneration has shown that the overall picture is rather more complicated than …

Autoantibody profiles represent important patient stratification markers in systemic sclerosis (SSc). Here, we performed serum-immunoprecipitations with patient antibodies followed by mass spectrometry (LC-MS/MS) to obtain an unbiased view of all possible autoantibody targets and their associated molecular complexes recognized by SSc.
