biosights: April 15, 2013 - Frog oocytes evade the checkpoint

submitted by: JCB
Most dividing cells possess a spindle assembly checkpoint that prevents them from entering anaphase until all their chromosomes are correctly attached to the metaphase spindle. Shao et al. reveal that Xenopus eggs lack this checkpoint, allowing them to undergo meiosis in the absence of microtubules or in the presence of monopolar spindles. This biosights episode presents the paper by Shao et al. from the April 15, 2013 issue of The Journal of Cell Biology and includes an interview with...

Diagnostic testing before cancer treatment

submitted by: mdanderson

Before starting cancer treatment, breast cancer patient Doris Thomas went through a series of tests at MD Anderson Cancer Center, all in one day. Since MD Anderson is a multidisciplinary hospital, it is typical for tests to be scheduled and completed under one roof in one day. Tests performed include an echocardiogram, lung CT scan, lab work and brain MRI.

Variant Visualizer Tutorial

submitted by: RGD.Videos

The examination of SNPs has undergone a recent change, and in response to this change, RGD has released the new Variant Visualizer tool (VarVis), taking the place of the old SNPlotyper tool. VarVis is a visualization and analysis tool for sequence variation. The data currently contains 22 rat strains sequenced by 4 independent labs.

Gene Annotator Tutorial

submitted by: RGD.Videos

The Gene Annotator takes a list of gene symbols, RGD IDs, GenBank accession numbers, Ensembl identifiers, and/or a chromosomal region, and retrieves annotation data from RGD. This tool will retrieve annotations from any or all ontologies used at RGD for genes and their orthologs, as well as links to additional information at other databases.
