2015-04-01T00:00:00+0000More than 82 per cent of the patients went into remission. 2015-04-01T00:00:00+00002015-04-01T00:00:00+0000NIH issued its ban after researchers in China announced experiments altering the gene in non-viable zygotes. 2015-04-15T00:00:00+00002015-04-22T00:00:00+0000The work was carried out by a team of scientists led by Junjiu Huang at Sun Yat-sen University in Guangzhou, China. The team used CRISRPR-Cas to modify a gene responsible for a blood disorder in spare embryos from fertility clinics that could not progress to a live birth. They published their results in P Liang , Y Xu , X Zhang et al, 'CRISPR/Cas9-mediated gene editing in human tripronuclear zygotes', Protein and Cell, 6/5 (2015): 363-72. 2015-05-01T00:00:00+0000Rose was an American biochemist who shared the 2004 Nobel Prize for Chemistry for contributing to understandings about how cells break down proteins. He first became interested in the puzzle of how cells identify and destroy unwanted proteins in the 1950s. In the late 1970s he showed that ubiquitin, a protein present in countless tissues, helps tag other proteins that need to be destroyed. It then attaches itself to another protein that is no longer functioning and takes it to the proteasome chamber to be broken down and recycled. Rose also helped develop a drug to treat multiple myeloma, a blood cancer. The drug works by disrupting the protein disposal mechanism and kills the cancer cells with a pile-up of protein. 2015-06-03T00:00:00+0000The drugs use a monoclonal antibody to block a protein known as PD-1, which functions as an immune checkpoint, being responsible for preventing the activation of T-cells. Promising results were presented to American Society for Clinical Conference from trials directed towards treating lung and skin cancer. 2015-06-05T00:00:00+0000Launched by Isis Pharmaceuticals (now Ionis) in partnership with Roche, the trial aimed to study the first therapy designed to silence the Huntingdon's disease gene and reduce the production of a protein responsible for the disease. 2015-07-21T00:00:00+0000K.B. Chiappinelli, P.L. Strissel, A. Desrichard, et al, 'Inhibiting DNA methylation causes an interferon response in cancer via dsRNA including endogenous retroviruses', Cell, 162 (2015), 974-86.2015-08-27T00:00:00+00002015-09-02T00:00:00+0000The group is made up of academic scientists, funders and regulators with an interest in embryo and stem cell research. It calls for the establishment of a roadmap for the management of the use of CRISPR in any human reproductive applications.2015-09-11T00:00:00+0000The group is made up of academic scientists, funders and regulators with an interest in embryo and stem cell research.

Research designed to understand why some women lose their babies before term. 2015-09-18T00:00:00+0000The pigs, a small breed known as Bama, had some of their genes disabled. They were developed for use in studying stem cells, gut microbiota, and Laron syndome, a type of dwarfism caused by a mutation in the human GHR gene. The announcement was made at Shenzhen International Biotech Leaders Summit.2015-09-23T00:00:00+0000Cpf1 is an RNA-guided endonuclease which appears in many bacterial species. It has the advantage that it is a smaller and simpler endonuclease than Cas9 so offers a means to overcome some of the limitations of the CRSIPR/Cas9 gene editing system. B Zetsche, J Gootenberg, O Abudayyeh, I Slaymaker, et al, 'Cpf1 Is a Single RNA-Guided Endonuclease of a Class 2 CRISPR-Cas System', Cell (2015): 1-13.2015-09-25T00:00:00+0000The operation was carried out at Moorfield Eye Hospital, London. It involved transplanting eye cells, called retinal pigment epithelieum, which were derived from stem cells. The surgery was performed by Lyndon Da Cruz as part of the London Project to Cure Blindness, a collaboration between Moorfields, the UCL Institute of Optahalmology and the National Institute for Health Research. 2015-09-29T00:00:00+0000The aim was to to inactivate 62 endogenous retroviruses in the pig embryos. All pigs have these viruses embedded in their genomes. The presence of such viruses, which can transmit diseases like cancer, is a major hurdle to the transplant of pig organs into humans. The gene editing work was carried out by the geneticist George Church of Harvard Medical School. He and his team presented the results to the US National Academy of Sciences. 2015-10-05T00:00:00+00002015-10-05T00:00:00+0000
