Dr Elaine Wong joined the Department of Biochemistry as a Research Assistant Professor in February 2013. At HKU, Dr. Wong obtained her PhD degree in 2006 and completed her post-doctoral training in developmental biology and molecular genetics. Dr. Wong underwent her second post-doctoral training in inner ear developmental and regenerative biology in Mount Sinai School of Medicine in New York in 2010. She is interested in understanding regulatory networks controlling mammalian auditory system development and complex disease mechanisms underlying human deafness, craniofacial and hindbrain disorders.
My research interest has been on the understanding of regulatory networks controlling mammalian organogenesis. More than 10 years’ research experience in developmental biology and hearing research. Disease mechanisms underlying human deafness and craniofacial disorders using knockout, transgenic mice, cellular and molecular approaches. Sonic hedgehog signaling genes in inner ear development; Eya1, Six1 and Hox genes regulatory networks associated to Human Branchio-oto-renal syndrome.
Major research themes and current projects
To understand the regulatory networks controlling mammalian organogenesis and complex disease mechanisms underlying human deafness. (1) Analyses of abnormal inner ear development of Irx3/5 knockout mutants to understand the mechanisms of Human Hamamy syndrome; (2) Genetic analyses of Cdo and Boc function in inner ear development; (3) The role of ciliogenesis in progressive hearing loss; (4) Regeneration of hair cells for treatment of human deafness by Human ES cells.
Techniques involve mammalian cochlear cell culture and real-time PCR, next generation sequencing (RNAseq), gene editing, ChIP sequencing and bioinformatics analyses. More than 10 years inner ear research experiences with auditory electrophysiology, hair cell functional analysis Patch clamp, isolation of hair cells, ips and ES cell culture, paint-filling for inner ear morphogenesis. Diverse cell-based assays such as viability and cell death, flow cytometry, Western Blotting, RNAi and coimmunoprecipitation CoIP experiments. Gene manipulation in mouse embryos and cochlea tissues techniques by injecting gene specific sh-RNA to generate loss-of-function system or overexpressing the target gene for gain-of-function system. Imaging techniques with multiphoton confocal live cell imaging. Neuronal dye tracing for brain and inner ear innervations, high resolution electron microscopy SEM, ultrastructural localization of the proteins involved in the stereocilia bundle at the top of sensory hair cells in the organ of Corti.
