Cross-Talk Between Factors Involved In Mrna Translation And Decay: A Dissertation, Shubhendu Ghosh

GSBS Dissertations and Theses

The proper workings of an organism rely on the accurate expression of genes throughout its lifetime. An important determinant for protein production is the availability of template mRNA molecules, the net effect of which is governed by their rates of synthesis vs. their rates of degradation. Normal mRNAs are proposed to be relatively stable in the cytoplasm while present in a protective, circularized conformation – the closed loop – through eIF4G-bridged interactions with 3’-bound poly(A) binding protein (Pab1p) and 5’-bound eIF4E. Introduction of a premature nonsense codon into an otherwise normal mRNA results in its rapid destabilization in cells ...


Combination Of 16s Rrna Variable Regions Provides A Detailed Analysis Of Bacterial Community Dynamics In The Lungs Of Cystic Fibrosis Patients, Melissa S. Doud, Michael Light, Gisela Gonzalez, Giri Narasimhan, Kalai Mathee 2010 Department of Biological Sciences, Florida International University

Combination Of 16s Rrna Variable Regions Provides A Detailed Analysis Of Bacterial Community Dynamics In The Lungs Of Cystic Fibrosis Patients, Melissa S. Doud, Michael Light, Gisela Gonzalez, Giri Narasimhan, Kalai Mathee

Department of Biological Sciences

Chronic bronchopulmonary bacterial infections remain the most common cause of morbidity and mortality among patients with cystic fibrosis (CF). Recent community sequencing work has now shown that the bacterial community in the CF lung is polymicrobial. Identifying bacteria in the CF lung through sequencing can be costly and is not practical for many laboratories. Molecular techniques such as terminal restriction fragment length polymorphism or amplicon length heterogeneity-polymerase chain reaction (LH-PCR) can provide many laboratories with the ability to study CF bacterial communities without costly sequencing. The aim of this study was to determine if the use of LH-PCR with multiple ...


Defining The Roles Of P300/Cbp (Creb Binding Protein) And S5a In P53 Polyubiquitination, Degradation And Dna Damage Responses: A Dissertation, Dingding Shi 2010 University of Massachusetts Medical School

Defining The Roles Of P300/Cbp (Creb Binding Protein) And S5a In P53 Polyubiquitination, Degradation And Dna Damage Responses: A Dissertation, Dingding Shi

GSBS Dissertations and Theses

p53, known as the “guardian of the genome”, is the most well-characterized tumor suppressor gene. The central role of p53 is to prevent genome instability. p53 is the central node in an incredibly elaborate genome defense network for receiving various input stress signals and controlling diverse cellular responses. The final output of this network is determined not only by the p53 protein itself, but also by other p53 cooperating proteins.

p300 and CBP (CREB-Binding Protein) act as multifunctional regulators of p53 via acetylase and ubiquitin ligase activities. Prior work in vitro has shown that the N-terminal 595 aa of p300 ...


Paraoxonase 1 Activity As A Predictor Of Cardiovascular Disease In Type 2 Diabetes, Rozaida @ Poh Yuen Ying 2010 University of Malaya

Paraoxonase 1 Activity As A Predictor Of Cardiovascular Disease In Type 2 Diabetes, Rozaida @ Poh Yuen Ying

Rozaida @ Poh Yuen Ying

The role of paraoxonase 1 in cardiovascular disease complications in type 2 diabetes mellitus is not fully understood. We studied paraoxonase activity towards paraoxon in 188 non-diabetic and 140 diabetic subjects using general linear models and univariate analysis. Adjusting for age revealed a reduction in activity towards paraoxon was associated with a significant increase in risk (p=0.023) for cardiovascular disease complications in diabetic patients. Multivariate analysis of two plasma measures of paraoxonase activity using paraoxon and diazoxon also showed reduced paraoxonase activity towards paraoxon was associated with a significant increase in risk (p=0.045) for cardiovascular disease ...


Role Of Genetics In Prediction Of Coronary Artery Disease, Andrey Yuabov 2010 Touro College

Role Of Genetics In Prediction Of Coronary Artery Disease, Andrey Yuabov

The Science Journal of the Lander College of Arts and Sciences

The following is the introduction of this article: Coronary arteries disease (CAD) is a leading cause of death in United States and rest of the world. It mostly involves atherogenic formation within the walls of the coronary arteries, which in turn restricts the adequate perfusion to the heart muscle. This leads to myocardial infarction and sudden death. In the past few decades the theories of coronary arteries disease pathogenesis have changed. The facts reveal that the onset of the disease can develop as early as childhood. The degree of the disease gradually progresses in stages and it is regarded as ...

Differential Genome-Wide Array–Based Methylation Profiles In Prognostic Subsets Of Chronic Lymphocytic Leukemia, Meena Kanduri, Nicola Cahill, Hanna Göransson, Camilla Enström, Fergus Ryan, Anders Isaksson, Richard Rosenquist

Global hypomethylation and regional hypermethylation are well-known epigenetic features of cancer; however, in chronic lymphocytic leukemia (CLL), studies on genome-wide epigenetic modifications are limited. Here, we analyzed the global methylation profiles in CLL, by applying high-resolution methylation microarrays (27 578 CpG sites) to 23 CLL samples, belonging to the immunoglobulin heavy-chain variable (IGHV) mutated (favorable) and IGHV unmutated/IGHV3-21 (poor-prognostic) subsets. Overall, results demonstrated significant differences in methylation patterns between these subgroups. Specifically, in IGHV unmutated CLL, we identified methylation of 7 known or candidate tumor suppressor genes (eg, VHL, ABI3, and IGSF4) as well as 8 unmethylated genes involved ...
