This website gives you lots of additional links to useful tools for modern biology. I find it very useful. Look for yourself!
Cre/loxP-database
http://www.mshri.on.ca/nagy/
Find out whether the gene that intrests you has already been floxed or not. Looking for a specific Cre-expressing mouse? The nagylab-site is the way to start your search before going through tedious literature searches. Please also add your own Cre/loxP-models in the list !
Endotext
http://www.endotext.com
Endotext.org is the web-based source of information on endocrine disease directed to physicians around the world caring for patients with these problems. It is comprehensive, authoritative, constantly up-dated, un-biased, and available without cost to physicians and trainees. This site covers the broad area of Clinical Endocrinology, emphasizing clinical endocrine practice, including the most current information on the manifestations of endocrine disease, diagnosis and treatment. Important advantage: as you will see: Endotext is based on the contributions of the experts in the field.
Ensembl
http://www.ensembl.org/
Ensembl is a general DNA database where you can find a nice overview of all interesting information about a specific gene.
Fly-TED, because also flies have testes....
http://www.fly-ted.org/
FlyTED, the Drosophila Testis Gene Expression Database, is a public database containing mRNA in situ images and ancillary data revealing the extent of expression of individual genes involved in spermatogenesis in the Drosophila melanogaster testis, both in wild type flies and in a number of meiotic arrest mutant strains.
Gene Ontology
http://www.geneontology.org
Do you want to know in which biological process a gene product is involved, what its molecular function is and where is located in the cell ? GO is the way to go!
GermOnline
http://germonline.unibas.ch/
GermOnline is a cross-species community annotation knowledgebase that provides microarray data relevant for the mitotic and meiotic cell cycle as well as gametogenesis. Importantly, GermOnline also integrates knowledge about genes important for sexual reproduction that is contributed and updated by members of the scientific community in collaboration with professional curators.
KEGG (Kyoto Encyclopedia of Genes and Genomes)
http://www.genome.jp/kegg/pathway.html
KEGG provides schematic overviews of different pathways. Very handy to get a clear picture of things in no time !
Medical Research Council Human Reproductive Sciences Unit
http://www.hrsu.mrc.ac.uk/
The MRC Human Reproductive Sciences Unit is the UK's leading institution undertaking research into reproductive health, and has integrated programmes on male and female infertility, contraception and hormone-dependent diseases. The Unit is a strategic investment by the Medical Research Council in the field of reproductive health.
This website provides contact details for leading scientists conducting research in reproductive biology, including information of research programs and the techniques used to best answer key research questions.
Reproductive Genetics Database
http://mrg.genetics.washington.edu/
The database holds information regarding genes and literature related to mammalian reproduction. You can search the database for gene expression profiles and knockout and mutant phenotypes. We have expression profiles for male mouse germ cell subtypes, male and female developmental stages, and the mouse epididymis.
Transgenic techniques and protocols
http://www.med.umich.edu/tamc/index.html
The website of the University of Michigan provides a nice overview of techniques used in transgenesis, but also protocols and hints to set up breedings and maintain your colony
