Understanding Ten-Eleven Translocation-2 In Hematological And Nervous Systems, Feng Pan
Understanding Ten-Eleven Translocation-2 In Hematological And Nervous Systems, Feng Pan
FIU Electronic Theses and Dissertations
I proposed the study of two distinct aspects of Ten-Eleven Translocation 2 (TET2) protein for understanding specific functions in different body systems.
In Part I, I characterized the molecular mechanisms of Tet2 in the hematological system. As the second member of Ten-Eleven Translocation protein family, TET2 is frequently mutated in leukemic patients. Previous studies have shown that the TET2 mutations frequently occur in 20% myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN), 10% T-cell lymphoma leukemia and 2% B-cell lymphoma leukemia. Genetic mouse models also display distinct phenotypes of various types of hematological malignancies. I performed 5-hydroxymethylcytosine (5hmC) chromatin immunoprecipitation sequencing (ChIP-Seq) and RNA …
Novel Insights Into The Mechanisms Of Regulation Of Tyrosine Kinase Receptors By Ras Interference 1, Adriana Galvis
Novel Insights Into The Mechanisms Of Regulation Of Tyrosine Kinase Receptors By Ras Interference 1, Adriana Galvis
FIU Electronic Theses and Dissertations
Receptor-tyrosine kinases (RTKs) are membrane bound receptors characterized by their intrinsic kinase activity. RTK activities play an essential role in several human diseases, including cancer, diabetes and neurodegenerative diseases. RTK activities have been regulated by the expression or silencing of several genes as well as by the utilization of small molecules.
Ras Interference 1 (Rin1) is a multifunctional protein that becomes associated with activated RTKs upon ligand stimulation. Rin1 plays a key role in receptor internalization and in signal transduction via activation of Rab5 and association with active form of Ras. This study has two main objectives: (1) It determines …
Ecdysis Triggering Hormone And Its Role In Juvenile Hormone Synthesis In The Yellow-Fever Mosquito, Aedes Aegypti, Maria Areiza
Ecdysis Triggering Hormone And Its Role In Juvenile Hormone Synthesis In The Yellow-Fever Mosquito, Aedes Aegypti, Maria Areiza
FIU Electronic Theses and Dissertations
Ecdysis triggering hormone (ETH) is a neuropeptide known for its role in the orchestration of ecdysis. However, its role in the regulation of Juvenile Hormone (JH) synthesis is unknown. In Aedes aegypti, JH is synthesized by the corpora allata (CA) and titers are tightly regulated by allatoregulatory factors. In this study I describe the effect of ETH on JH synthesis during the late pupal stage and in the adult female after blood feeding. Analysis of ETH receptor (ETHRs) expression showed that ETHRs are present in both the CA and the corpora cardiaca (CC), a neurohemal organ. The data suggest …
