How does day length affect aggression in mice? It's in the genes
... The researchers had another idea that would use microarrays -- small computer chips that examine thousands of genes at the same time to see which ones are active. They compared genes from mice living in winter-like short days with those living under longer day lengths. The results showed that certain genes as...Decoding gene expression in cancer tumors using noninvasive imaging
...Chang had been using the gene activity patterns of microarrays to predict cancer outcome. Segal developed algorit...systematically connect the gene activity seen with microarrays to imaging patterns, enabling us to translate images to gene patterns, and ultimately to the outcome...CSIRO scientists join fight to save 'Tassie devil'
... use a variety of techniques including microscopy, microarrays and a range of molecular techniques to search for infectious agents, markers for disease and to determine where the tumours originate. We will be working in a number of areas including establishing whether a virus or other infectious agents are ...Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state
..., the database includes data from thousands of DNA microarrays submitted mainly by scientists in Canadas Stem Cell Network. All data is freely available at www.stembase.ca . Lead author Ms. Pearl Campbell noted that understanding how stem cells maintain their identity is key to the emerging field of regenera...New tumor markers -- 'Spot the differences'
... to do so. In order to carry out this work we used microarrays or DNA-chips, a technique used for multiple analyses. It allows the detection and quantification of messages sent by thousands of genes. We analysed biopsies of PC as well as samples of healthy pancreas. The RNA (thousands of messages sent by cells) ...Gut check: Tracking the ecosystem within us
...e or activity of thousands of genes. The team used microarrays to profile the mixture of bacterial DNA in an average of 26 stool samples per infant over the course of the first year of life, beginning with the first stool after birth. For a handful of these samples, they compared the results that they had obt...Genomics study provides insight into the evolution of unique human traits
...ong these species, Sikela and colleagues used DNA microarrays containing over 24,000 human genes to perform comparative genomic hybridization experiments. They compared DNA samples from humans to those of nine other primate species: chimpanzee, gorilla, bonobo, orangutan, gibbon, macaque, baboon, marmoset, an...News tips from the Journal of Neuroscience
...olf In this week's Journal , Griffin et al. used microarrays to narrow in on genes affected in three peripheral nerve injury models of neuropathic pain. The most highly regulated were involved in the microglial complement cascade. Messenger RNAs for C1qb, C3, and C4 were upregulated in the dorsal horn of the s...... ago. This tool, which comprises tailored designed microarrays or gene chips and computer algorithms, allows the simultaneous measurement of thousands of alternative splicing events in cells and tissues. Until recently researchers studied splicing regulation on a gene by gene basis. Now we can obtain a picture o...
