The tg-list will be transferred to the ISTT web server

The International Society for Transgenic Technologies (ISTT) is pleased to announce that the transgenic-list (tg-l) owner and administrator, Dr. Peter Sobieszczuk and the ISTT have just signed an agreement to transfer the tg-l from its current location, at the web server of the Imperial College (London, UK), to the ISTT web server.

The tg-l was created by Peter Sobieszczuk in July, 1996, to serve the global research community specializing in genetic modifications of experimental laboratory animals. Since then, the tg-l has been hosted by three academic institutions: the IGBMC in Strasbourg, the University of Manchester, UK, and the Imperial College in London, UK where it is currently hosted. The ISTT would like to acknowledge the excellent work of Peter and his assistants in maintaining the list since its inception for the benefit of everyone who has been a part of this list. The tg-l has proven to be a valuable source of knowledge and advice, helping many newcomers to rapidly familiarize themselves with the field of animal transgenesis, and facilitating the exchange of protocols and experiences among all of its members.

The ISTT, in accordance with one of its main aims, as expressed in the ISTT bylaws (Art. 3a), is most proud to host the tg-l for the benefit of the entire community of scientists, technicians, students and anyone else, in general, interested in animal transgenesis.

At the ISTT server, the tg-l will continue being public (anyone may subscribe, including ISTT members and non-members alike), unmoderated (messages will not be altered by the list administrator) and closed (only subscribers may post messages). Subscription to the tg-l will also continue being free, automatic and very simple, from a suitable page that will be installed within the public area of the ISTT web server.

The actual transfer of tg-l from the Imperial College to the ISTT web server will not occur until current agreements in place will be fulfilled. This is expected to occur by December 31, 2011 or, earlier, whenever possible. The actual transfer will be duly informed in subsequent messages that will be posted through the ISTT_list and through the tg-l.

best regards,

Lluis Montoliu
President of the ISTT

ISTT is a new AAALAC's Member Organization

The International Society for Transgenic Technologies (ISTT) is pleased to announce that has been approved as a new AAALAC’s Member Organization after our application we registered in July, with the massive support of ISTT members. AAALAC stands for the “Association for Assessment and Accreditation of Laboratory Animal Care”. AAALAC International is a private, nonprofit organization that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. AAALAC’s Member Organizations are a select group of prestigious scientific, professional and educational groups with an interest in advancing biomedical research and animal well-being in science. Each Member Organization appoints a representative to serve on the AAALAC International Board of Trustees.

Genome sequencing of 17 mouse inbred strains

Mouse genomic variation and its effect on phenotypes and gene regulation. Keane et al. Nature 2011, 289–294,  (15 September 2011), doi:10.1038/nature10413

Mouse genomic variation and its effect on phenotypes and gene regulation. Keane et al. Nature 2011, 289–294, (15 September 2011), doi:10.1038/nature10413

Most of our current understanding and genome research in mice has been based, so far, on the genome of the mouse inbred strain C57BL/6J, published in 2002 and accessible through a number of genome browsers, such as Ensembl. Yesterday, Keane et al. published in Nature the results of their sequencing efforts and the release of the genome sequences from 17 additional mouse inbred strains: C3H/HeJ, CBA/J, A/J, AKR/J, DBA/2J, LP/J, BALB/cJ, NZO/HlLtJ, NOD/ShiLtJ, 129S5SvEv<Brd>, 129P2/OlaHsd, 129S1/SvImJ, C57BL/6NJ, and the four wild-derived inbred strains CAST/EiJ, PWK/PhJ, WSB/EiJ and SPRET/EiJ. This is an enormous amount of information, obtained using next-generation sequencing, that these researchers from The Wellcome Trust Sanger Institute and other collaborating institutions now release to the public scientific community. Most of these inbred strains are very relevant in biomedical research and they are regularly used for the generation of genetically-modified mice. Notably, among them the C57BL/6NJ inbred strain, selected by the International KnockOut Mouse Consortium (IKMC) to produce the collection of systematic gene knockouts covering the entire mouse genome. This publication and the subsequent analyses derived from this study should greatly contribute to our understanding of the genetic diversity among different mouse strains and the different phenotypes that are often observed across inbred strains, associated with identical genetic modifications.

Advanced Protocols for Animal Transgenesis. An ISTT Manual

Advanced Protocols for Animal Transgenesis. An ISTT Manual

The International Society for Transgenic Technologies (ISTT) is most pleased to announce the publication of its first book, entitled “Advanced Protocols for Animal Transgenesis. An ISTT Manual“, edited by Shirley Pease and Thom Saunders, and published by Springer (2011), in collaboration with the ISTT. This laboratory manual provides almost all current methods that can be applied to the creation and analysis of genetically modified animals. The chapters have been contributed by leading scientists, most of them members of the ISTT, who are actively using the technology in their laboratories. Based on their first-hand experience the authors also provide helpful notes and troubleshooting sections.

Topics range from standard techniques, such as pronuclear microinjection of DNA, to more sophisticated and modern methods, such as the derivation and establishment of embryonic stem (ES) cell lines, with defined inhibitors in cell culture medium. In addition, related topics with relevance to the field are addressed, including global web-based resources, legal issues, colony management, shipment of mice and embryos, and the three R’s: refinement, reduction and replacement. This book comprises 26 chapters,  109 illlustrations and 669 pages.
