First Embryonic Stem Cells Cloned From A Man's Skin

Posted: Published on April 17th, 2014

hide captionThis mouse egg (top) is being injected with genetic material from an adult cell to ultimately create an embryo and, eventually, embryonic stem cells. The process has been difficult to do with human cells. Eighteen years ago, scientists in Scotland took the nuclear DNA from the cell of an adult sheep and put it into another sheep's egg cell that had been emptied of its own nucleus. The resulting egg was implanted in the womb of a third sheep, and the result was Dolly, the first clone of a mammal. Dolly's birth set off a huge outpouring of ethical concern along with hope that the same techniques, applied to human cells, could be used to treat myriad diseases. But Dolly's birth also triggered years of frustration. It's proved very difficult to do that same sort of DNA transfer into a human egg. Last year, scientists in Oregon said they'd finally done it, using DNA taken from infants. Robert Lanza, chief scientific officer at Advanced Cell Technology, says that was an important step, but not ideal for medical purposes. "There are many diseases, whether it's diabetes, Alzheimer's or Parkinson's disease, that usually increase with age," Lanza says. So ideally scientists … Continue reading

Dual role: Key cell division proteins also power up mitochondria

Posted: Published on April 17th, 2014

PUBLIC RELEASE DATE: 17-Apr-2014 Contact: Dorsey Griffith dorsey.griffith@ucdmc.ucdavis.edu 916-734-9118 University of California - Davis Health System (SACRAMENTO, Calif.) An international team led by researchers at UC Davis has shown that the cyclin B1/Cdk1 protein complex, which plays a key role in cell division, also boosts the mitochondrial activity to power that process. This is the first time the complex has been shown to perform both jobs. This newfound ability could make cyclin B1/Cdk1 an excellent target to control cellular energy production, potentially advancing cancer care and regenerative medicine. The research was published online today in the journal Developmental Cell. "These proteins not only control the cell cycle, but they also moonlight to increase mitochondrial energy," said lead author Jian Jian Li, director of Translational Research at the UC Davis Comprehensive Cancer Center and professor in the Department of Radiation Oncology. "They synchronize these processes because the cell cycle cannot proceed without the extra energy." The cyclin B1/Cdk1 complex has long been known to intervene at a critical point in the cell cycle, the G2 phase, during which cell division pauses after DNA replication to check for genetic damage. Once any damage has been repaired, the cell can move into mitosis … Continue reading

Refining the language for chromosomes

Posted: Published on April 17th, 2014

PUBLIC RELEASE DATE: 17-Apr-2014 Contact: Marjorie Montemayor-Quellenberg mmontemayor-quellenberg@partners.org 617-525-6383 Brigham and Women's Hospital Boston, MA When talking about genetic abnormalities at the DNA level that occur when chromosomes swap, delete or add parts, there is an evolving communication gap both in the science and medical worlds, leading to inconsistencies in clinical and research reports. Now a study by researchers at Brigham and Women's Hospital (BWH) proposes a new classification system that may standardize how structural chromosomal rearrangements are described. Known as Next-Gen Cytogenetic Nomenclature, it is a major contribution to the classification system to potentially revolutionize how cytogeneticists worldwide translate and communicate chromosomal abnormalities. The study will be published online April 17, 2014 in The American Journal of Human Genetics. "As scientists we are moving the field of cytogenetics forward in the clinical space," said Cynthia Morton, PhD, BWH director of Cytogenetics, senior study author. "We will be able to define chromosomal abnormalities and report them in a way that is integral to molecular methods entering clinical practice." According to the researchers, advances in next-generation sequencing methods and results from BWH's Developmental Genome Anatomy Project (DGAP) revealed an assortment of genes disrupted and dysregulated in human development in over 100 … Continue reading
