Dust off the crystal ball: It’s time for STAT’s 2020 Nobel Prize predictions. Huda Zoghbi Lab. In the Lab. 2016 Oct 25;5. pii: e19809. These mice lack cerebellar granule neurons, pontine neurons, hair cells in the vestibular and auditory systems, and the D1 interneurons of the spinocerebellar tracts. America's fourth largest city is a great place to live, work and play. Male Mecp2308 mice appear normal up to six weeks of age, when they develop tremors, seizures, coordination problems, social behavior abnormalities, and forepaw stereotypies similar to the hand-wringing seen in patients. 713–798–6558. She started her studies in biological sciences and did one year of medical school at the American University of Beirut in Lebanon. Dr. Zoghbi and her collaborators have unraveled the genetic underpinnings of a number of devastating neurological disorders, including Rett syndrome and spinocerebellar ataxia type 1 (SCA1). Publications . October 2, 2020. Reprints. Third, we found that mutant Ataxin-1 has to be in its native complexes (that contain Capicua) to make its pathogenic affects. The laboratory uses genetic, biochemical, and cell biological approaches to explore the pathogenesis of polyglutamine neurodegenerative diseases and Rett syndrome, and to study genes essential for normal neurodevelopment. Plasmid pLenti-DsRed_IRES_MAPT:EGFP from Dr. Huda Zoghbi's lab contains the insert DsRed-IRES-MAPT-EGFP and is published in Elife. Glutamine-expanded Ataxin-1 causes disease by a gain-of-function mechanism given that mice lacking this protein do not reproduce SCA1 features. Huda Zoghbi, MD | Baylor College of Medicine. This model predicts that most proteins that interact with wild-type Ataxin-1 should interact with the mutant protein and that modifications of Ataxin-1 that might alter its conformation are critical to pathogenesis. Moreover, several of the direct physical interactors are modifiers of disease phenotypes in animal models. Get in touch. Start of Lecture 3 (00:11) From The Howard Hughes Medical Institute the 2003 Holiday Lectures on Science. Located on the X chromosome, MECP2 encodes a protein that binds methylated cytosines, helping to orchestrate gene silencing via DNA methylation. ©1998-2020 Baylor College of Medicine® | One Baylor Plaza, Houston, Texas 77030 | (713)798-4951Have an edit or suggestion for this page? Huda Zoghbi’s experience diagnosing patients with Rett syndrome motivated her scientific research. In an interview with ... She began her independent lab studying the adult-onset neurodegenerative disease spinocerebellar ataxia type 1 and branched out to study other neurodegenerative conditions. UTD Green Fellow. Genome annotation related files including junction database (known … Addgene is a nonprofit plasmid repository dedicated to improving life science research. That a single gene controls the genesis and/or differentiation of multiple components of the proprioceptive pathway was a surprise. Although she initially trained to be a clinical pediatric neurologist, Huda Y. Zoghbi, MD, soon found herself drawn to research. Fall 2019 (Oct-Dec) Lupita Rios . Learn more about research in the Huda Zoghbi Lab. Huda Yahya Zoghbi (Arabic: هدى الهبري الزغبي Hudā al-Hibrī az-Zughbī; born 1954), born Huda El-Hibri, is a Lebanese-born American geneticist, and a professor at the Department of Molecular and Human Genetics, Baylor College of Medicine.

In 1999, we discovered that Rett syndrome is caused by mutations in the gene encoding methyl-CpG-binding protein 2 (MECP2). Recently we found that MeCP2 regulates the expression of corticotropin-releasing hormone (CRH) by binding the promoter of the Crh gene. Heading. ©1998-2020 Baylor College of Medicine® | One Baylor Plaza, Houston, Texas 77030 | (713)798-4951Have an edit or suggestion for this page? They also collaborate with labs studying Drosophila to study the function of proteins Our ultimate goal is to correlate phenotypes to specific neurons and to identify the gene expression changes within such neurons that could be modulated to modify the phenotypes. Davut Pehlivan, MD, Instructor of Neurology at Texas Children’s Hospital, studies translational neuroscience because of the kids with brain disorders he has seen in the clinic. We are treating Mecp2308 mice with Crh receptor-1 antagonist to determine if this will subdue the anxiety and stress phenotypes. Diese ambitionierte Einrichtung befindet sich im Herzen des Texas Medical Center, ganz in der Nähe des … The spinocerebellar ataxias (SCAs) are dominantly inherited neurodegenerative disorders characterized by a progressive loss of balance and coordination, and eventually the inability to coordinate swallowing and breathing. Huda Y. Zoghbi, M.D. “He loved learning, and he always pushed my sister and brothers and me to read,” Zoghbi recalls. We and others have discovered that MECP2 mutations cause a broad spectrum of phenotypes in both females and males. She and her classmates ate in the hospital cafeteria, which they accessed through an underground tunnel. In addition we are performing genetic and biochemical studies to gain better insight about the in vivo function of the native Ataxin-1 complexes and the role of Capicua in the nervous system. Math1 is also essential for secretory cells in the gut (Paneth, goblet, and enteroendocrine cells), and the enteroendocrine cells secrete neuropeptides that modulate gut proprioception. Fall 2019 (Oct-Dec) Nisha Gupta . We generated a mouse model by creating a mutation that truncates the protein post–amino acid 308. Identification of the Math1-dependent neurons allowed us to propose that Math1 redefines the rhombic lip and its derivatives. doi: 10.7554/eLife.19809. This finding suggested that the symptoms of Rett syndrome were caused by a defect in the function of MECP2: controlling the activity of other genes. By Sharon Begley @sxbegle. Institute for Clinical & Translational Research. In her career, Zoghbi faced many obstacles. Humay (Gulhumay) Gardashova . We are continuing to characterize the Math1-null mice to pinpoint the neurons involved in the respiration phenotype, and we are pursuing the identification of Math1's downstream targets to define the molecular pathways involved in the differentiation of the diverse cell types dependent on Math1. Her work helped elucidate mechanisms of Rett syndrome and spinocerebellar ataxia type 1. Genetic studies in mice and fruit flies have shed the most light on SCA1 pathogenesis. Die Leiterin Huda Zoghbi, deren Labor feststellte, dass Mutationen an MECP2 das Rett-Syndrom auslösen, stellt sich ein Forschungszentrum vor, wo Wissenschaftler mit verschiedenen Interessen in einem Umfeld des kontinuierlichen und interdisziplinären Austauschs arbeiten können. Neither of her parents went to college, but her father, who worked from the age of 17 as an extractor of olive oil, was a self-taught scholar. Immigrants make the journey to the United States for a number of reasons. Second, we found that the AXH domain in Ataxin-1 is a key mediator of the neuropathology in part through interactions with the transcriptional repressors Gfi-1 and Capicua. Lastly, we recently found that the Ataxin-1 paralog (Ataxin-1 like) can suppress neurodegeneration in the SCA1 knock-in mice by displacing Ataxin-1 from its native complex facilitating its sequestration into inclusions. The glutamine tract seems to mediate its toxicity by modulating the activity of the AXH domain. In her laboratory at Baylor College of Medicine, Dr. Huda Zoghbi and her colleagues have found two neuronal lineages in the hindbrain that act as ‘conductors’ of an exquisite biological symphony. Research Area: Pathogenesis of neurodegenerative disease, Rett syndrome, normal neurodevelopment, Ataxin-1, Akt, Mouse models (PI: Huda Zoghbi)... Huda Zoghbi Lab Skip to main content To our surprise we found that several ataxia proteins interact directly or indirectly and that certain RNA-binding proteins and transcription regulators form key hubs in the ataxia network. Lab Members . This led us to propose that wild-type Ataxin-1 might take on a conformation that resists clearance or interacts strongly with other proteins and that such conformation is favored by the expanded polyglutamine tract. “I was encountering a lot of patients who had devastating neurological problems, and many of them were genetic,” she recalls.

For a few months during medical school, Huda Zoghbi slept in a windowless closet inside a women’s bathroom at the American University of Beirut. Content. This led us to propose that duplications of MeCP2 might lead to postnatal neurologic disorders, which indeed is proving to be the case. Dr. Huda Y. Zoghbi is a professor in the Departments of Pediatrics, Molecular and Human Genetics, Neurology and Neuroscience at Baylor College of Medicine. Huda Zoghbi 2011 Neuroscience Prize. Dr. Huda Y. Zoghbi’s lab works hand-in-hand with The Blue Bird Circle Rett Center at Texas Children’s Hospital to provide cutting edge treatment for girls and women with Rett syndrome. Inside the Lab with Davut Pehlivan, MD. This basic research effort discovered that mutations in the MECP2 gene cause Rett syndrome. Rotation Student. Huda Zoghbi: I was really intrigued by one thing about this syndrome — the girls are healthy and look healthy when they’re born and achieve certain milestones, and then they lose those acquired skills.And we know that it’s not degenerative because they can live into adulthood. The Huda Zoghbi Lab has deposited plasmids at Addgene for distribution to the research community. 1985-1989; 1990-1999; 2000-2009; Contact Us. Contact. We isolated the mouse atonal homologue 1 (Math1) because of the importance of atonal for the development of balance and hearing organs in Drosophila. Our laboratory uses genetic, cell biological, and biochemical approaches to explore the pathogenesis of polyglutamine neurodegenerative diseases, the function of Math1 in neurodevelopment, and how MECP2 mutations cause postnatal neurodevelopmental disorders. Huda Yahya Zoghbi (geborene Huda El-Hibri; * 20. Zoghbi said she was not expecting so many children, the majority being young girls, to reach out to her to say how they had never thought that a career in science and medicine could be just as glamorous as the lives of celebrities they see on the red carpet and even more rewarding. Juni 1954 in Beirut) ist eine libanesisch-US-amerikanische Neurologin. Recognizing the importance of protein interactions for mediating SCA1 pathogenesis, and given that SCA1 shares clinical and pathological features with several other inherited ataxias, we proposed that understanding the interactions of Ataxin-1 as they relate to the interactions of proteins implicated in other ataxias might provide better insight about molecular mechanisms leading to Purkinje cell degeneration and ataxia. Dr. Marvin Fishman with Dr. Huda Zoghbi in her lab. To test this hypothesis we used proteins whose genes are mutated in various ataxias to develop a "phenotype-based" protein interaction network (ataxia interactome) in collaboration with Marc Vidal at the Dana-Farber Cancer Institute. Institute for Clinical & Translational Research, Department of Molecular and Human Genetics, Section of Neurology and Developmental Neuroscience. The finding that Mecp2308 mice have altered RNA-splicing patterns in the cerebral cortex that are significantly different from these of wild-type animals led us to propose that MeCP2 acts as repressor, but when it is released from the promoter region, it participates in its second function as a splicing regulator of the newly transcribed genes. Even in her education, the war could have disrupted her path to where she is today. Peggy Goodell (Stem Cells and Regenerative Medicine, Baylor College of Medicine) DNA methylation in normal and malignant hematopoiesis. Girls affected with Rett syndrome appear to develop normally for the first 6 to 18 months of life, then lose the ability to speak and socialize, and develop tremors, ataxia, seizures, and stereotypic hand-wringing movements. Our functional and pathogenesis studies, revealed that MeCP2 interacts with the RNA-binding protein YB-1 and that this interaction affects alternative splicing of reporter cassettes regulated by YB-1. In collaboration with the Orr lab, we found that residue S776 in Ataxin-1 is necessary for Ataxin-1's toxicity. Content . Take Dr. Huda Zoghbi’s decade-long study on the genetic origins of Rett syndrome as a starting point. She is also an investigator at the Howard Hughes Medical Institute and the director of the Jan and Dan Duncan Neurological Research Institute (NRI) at Texas Children's Hospital. In males, the inactivating mutations cause severe neonatal encephalopathy and death in infancy, whereas milder mutations may cause mental retardation, motor dysfunction, and psychosis. We tested this hypothesis in cells, fruit flies, and mice and found that indeed chaperone overexpression mitigates SCA1 neuropathology and phenotypes. This plasmid is available through Addgene. Our analysis of the cellular distribution of MeCP2 during development determined that MeCP2 is in mature neurons and that the number of MeCP2-positive cortical neurons increases up to 10 years of age in humans. Dr. Huda Zoghbi is the Ralph D. Feigin professor at Baylor College of Medicine, an investigator at the Howard Hughes Medical Institute, and the director of the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital.
