Gq Noncanonical Roles In Translational Regulation, Brett Demarco
Gq Noncanonical Roles In Translational Regulation, Brett Demarco
Electronic Theses and Dissertations
This study investigates protein nucleic acid interactions, focusing on G-quadruplex (GQ) forming DNA/RNA in human disease. GQ structures are formed in DNA/RNA, when four guanine residues form planar tetrads stabilized by Hoogsteen base pairing, that stack forming a GQ structure stabilized by potassium ions. These GQ structures are targeted by the arginine glycine-glycine (RGG) RNA-binding domain. Fragile X mental retardation protein (FMRP), a translation regulator protein implicated in the fragile X syndrome, has an RGG domain and has been previously shown to interact with neuronal GQ forming messenger RNA (mRNA). We have investigated three neuronal FMRP mRNA targets that we …
Cooperative Regulation Of Translational Repression By Fmrp And The Mirna Pathway, Navneeta Kaul
Cooperative Regulation Of Translational Repression By Fmrp And The Mirna Pathway, Navneeta Kaul
Electronic Theses and Dissertations
Fragile X syndrome (FXS) is the most common inherited monogenic cause of intellectual disability. FXS patients exhibit social and language deficits, hyperactivity, seizures, growth abnormalities, macroorchidism, anxiety, and epilepsy. FXS is caused by the transcriptional silencing of the fragile X mental retardation gene 1 (Fmr1), resulting in the loss of the fragile X mental retardation protein (FMRP). FMRP is a selective mRNA binding protein that plays a role in translation repression. Studies suggest that FMRP utilizes the miRNA pathway to repress translation of its target mRNAs through an unknown mechanism. The aim of my thesis is to investigate …
Computational Analysis Of Genomic Variants Affecting Predicted Microrna:Target Interactions In Prostate Cancer., Angélica Paola Hernández Pérez
Computational Analysis Of Genomic Variants Affecting Predicted Microrna:Target Interactions In Prostate Cancer., Angélica Paola Hernández Pérez
KGI Theses and Dissertations
Prostate cancer (PCa) is the most common cancer of men in the United States and is third only to lung and colon as a cause of cancer death. Clinical behavior of the disease is variable and the combination of prostate-specific antigen (PSA) screening and Gleason score staging are currently the best available molecular and pathology tools to predict outcomes. Cancer biology research establishes microRNAs (miRNAs) as key molecular components in both normal and pathological states. Thus, elucidating miRNAs perturbed by genomic alterations will expand our understanding of the molecular taxonomy of PCa with the aim to complement current practices in …
Biology Of Exosomes And Their Microrna Cargos In Human And Bovine Milk, Amy Lynn Leiferman
Biology Of Exosomes And Their Microrna Cargos In Human And Bovine Milk, Amy Lynn Leiferman
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Exosomes are small, cargo-containing vesicles secreted by cells to facilitate intercellular communication. Of exosome cargos, microRNAs are especially interesting because of their involvement in gene regulation. Recently, our lab has shown that exosomes and their microRNA cargo are absorbed through the diet and elicit effects exogenously. Human and animal milk contain exosomes, which may have implications in infant and adult nutrition. There is evidence that bovine milk exosomes enhance growth of murine C2C12 myotube cell cultures, but whether this translates to muscle in vivo is unknown. The USDA National Nutrient Database for Standard Reference is lacking up-to-date information about human …

Esophageal adenocarcinoma (EAC) is a highly aggressive malignancy that develops from Barrett's esophagus (BE), an intestinal metaplasia of the distal esophagus. microRNAs (miRNAs), short non-coding regulatory RNAs, are frequently dysregulated in BE and are thought to play key roles in the onset of BE and its progression to EAC. miRNAs thus have potential diagnostic and prognostic value and are increasingly being used as cancer biomarkers. This review summarizes the current literature related to miRNAs that are dysregulated in BE within the context of Hedgehog, Notch, MAPK, NF kappa-B, Wnt and epithelial-mesenchymal transition (EMT) signaling which are thought to drive BE …
