Mistranslating Trnas Alter The Heat Shock Activation By Hsf1, Rebecca Dib Aug 2022

Mistranslating Trnas Alter The Heat Shock Activation By Hsf1, Rebecca Dib

Undergraduate Student Research Internships Conference

Translation, or the production of protein from an mRNA blueprint, is among the most fundamental processes to life as we know it. tRNAs are essential to accurate translation, as they decode the codons of mRNA and recruit corresponding amino acids. Variant tRNAs with anticodon mutations can decrease translational fidelity by recruiting the incorrect amino acid, an aberrant process known as mistranslation. When proteins are produced with incorrect amino acid sequences, they may misfold. The heat shock response functions to alleviate cellular stress caused by misfolded proteins, either by refolding or targeting misfolded proteins for degradation. Hsf1 acts as a transcriptional …

Assessing The Structure-Function Relationships Of The Apolipoprotein(A) Kringle Iv Sub-Type 10 Domain, Matthew J. Borrelli Aug 2019

Assessing The Structure-Function Relationships Of The Apolipoprotein(A) Kringle Iv Sub-Type 10 Domain, Matthew J. Borrelli

Electronic Thesis and Dissertation Repository

Elevated plasma lipoprotein(a) (Lp(a)) is the most prevalent heritable risk factor in the development of cardiovascular disease. The apolipoprotein(a) (apo(a)) component of Lp(a) is strongly implicated in the pathogenicity of Lp(a). It is hypothesized that the inflammatory potential of Lp(a)/apo(a) is mediated by the lysine binding ability of the apo(a) kringle IV10 (KIV10) domain, along with its covalently bound oxidized phospholipid (oxPL). Using targeted mutagenesis, two novel null alleles for the LPA gene that generate non-secretable apo(a) species have been identified, resulting from amino acid substitutions in the KIV10 domain. A potential mechanism by which KIV10 oxPL modification is enriched …

P33. Design And Evaluation Of An Escherichia Coli Biomarker For Indication Of Ph, Kevin X. Zhou, Luana Langlois, Ashmita Singh, John Prince

Western Research Forum

Measuring pH is one of the most commonly used techniques in both the laboratory as well as the field due to its importance in a multitude of biochemical processes. Traditional methods of measuring pH may be highly developed in accuracy and precision but often involve disruption of the environment. Biological markers offer an alternative that allows for long-term pH monitoring. This innovative approach allows for vast applications such as in the manufacturing, food processing and research industries. Under moderate acidic conditions, the asr (acid shock RNA) gene is highly inducible and has been demonstrated to be crucial for growth at …


Genetic Approaches To Studying Complex Human Disease, Joseph B. Dube Jun 2013

Genetic Approaches To Studying Complex Human Disease, Joseph B. Dube

Electronic Thesis and Dissertation Repository

Common, complex diseases such as cardiovascular disease (CVD) represent an intricate interaction between environmental and genetic factors and now account for the leading causes of mortality in western society. By investigating the genetic component of complex disease etiology, we have gained a better understanding of the biological pathways underlying complex disease and the heterogeneity of complex disease risk. However, the development of high throughput genomic technologies and large well-phenotyped multi-ethnic cohorts has opened the door towards more in-depth and trans-disciplinary approaches to studying the genetics of complex disease pathogenesis. Accordingly, we sought to investigate select complex traits and diseases using …


Elucidating The Genetic Determinants Of The Archetypal Complex Disease Hypertriglyceridemia, Christopher T. Johansen Aug 2011

Elucidating The Genetic Determinants Of The Archetypal Complex Disease Hypertriglyceridemia, Christopher T. Johansen

Electronic Thesis and Dissertation Repository

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in Canada. Among non-traditional risk factors, plasma triglyceride (TG) concentration is re-emerging as a significant risk factor. Patients with hypertriglyceridemia (HTG) – an archetypal complex phenotype defined by fasting plasma TG concentration >95th percentile – thus have significantly increased CVD risk, compounded by associated co-morbidities such as obesity, metabolic syndrome and type 2 diabetes. However, the molecular pathways contributing to HTG susceptibility are incompletely defined. A better understanding of the genetic determinants that underlie the phenotypic spectrum of plasma TG and HTG susceptibility is necessary to identify novel …
