Data presented in this webinar illustrates the value of live cell analysis at the single-cell level to identify differences in expression levels across populations of cells. The cells remain intact for downstream analysis. Our experts also discuss the use of SmartFlare RNA detection probes for the direct quantification of circulating miRNAs with rapid processing of blood plasma/serum, which is done without the use of enzymes. Using circulating miRNAs with established roles in cancer and quality control, we can accurately detect these miRNAs in plasma using a microplate fluorometer within an hour after plasma preparation.

Library preparation methods continue to be challenged by the requirement for faster and more efficient protocols, using lower input amounts. In this online seminar, recorded Feb. 7, 2013, experts discuss new approaches to tackle these challenges, particularly for bacterial and exome sequencing.

Alex Pearlman hopes his discoveries will affect the way prostate cancer patients are treated. With other researchers, he has developed a genomic copy-number alteration-based prognostic model to predict, at the earliest stage possible, the likelihood that a local prostate cancer will metastasize.
The model was featured in a recent issue of the Journal of Probability and Statistics, a paper that he calls the "culmination of 10 years of work" and the "methods paper" for what he hopes will soon be a clinical test. "The finish line is pretty clear," says Pearlman, who is at New York City's Albert Einstein College of Medicine. "It is to develop a US Food and Drug Administration-approved kit to predict prostate cancer metastases and to alleviate men of needless surgeries and radiation treatment."
The Natural History Museum is amassing tissue samples from around the world to analyze with genomic tools.
A survey suggests that public interest in biomedical research is high, but knowledge is not as high.
Scientists and others call for an end of using impact factors to evaluate researchers' work.
Variation and genetic control of protein abundance in humans
Wu, Candille, et al. Nature
Stanford University scientists publish a study demonstrating high-throughput human proteome quantification, and its combination with DNA variation and transcriptome information to add a "new dimension" to the characterization of gene expression regulation. The investigators used isobaric tag-based quantitative mass spectrometry to determine relative protein levels of 5,953 genes in lymphoblastoid cell lines from 95 diverse individuals genotyped in the HapMap Project. They found that protein levels are heritable molecular phenotypes and have considerable variation between individuals, populations, and sexes. Additionally, the investigators found protein quantitative trait loci, including variants not detected by previous transcriptome studies.
Genomic architecture of adaptive color pattern divergence and convergence in Heliconius butterflies
Supple, Hines, et al. Genome Research
A group from the US, UK, and Colombia describes findings from a comparative genomics-based study on a form of adaptive variation in butterflies known as mimetic wing coloring. By sequencing co-mimicking Heliconius butterflies from two species and a handful of hybrid zones, researchers narrowed in on a color pattern-associated site near a gene already implicated in red color variation — an apparent regulatory region suspected of evolving by convergence in the two species distantly related species. "Using a combination of next-generation sequencing analyses, we have refined our understanding of the genetic architecture of wing pattern variation in Heliconius," they write, "and gained important insights into the evolution of novel adaptive phenotypes in natural populations."
