Evidence for conserved post-transcriptional roles of unitary pseudogenes and for frequent bifunctionality of mRNAs
November 16, 2012Exploring the human genome with functional maps.
November 11, 2012This paper has: (1) Large-scale datasets compiled from literature and databases, (2) comprehensive gold standards for positive and negative samples, (3) a classifier algorithm (regularized Bayesian), and (4) further analysis beyond “functional prediction”, including an interaction network. It predicts a list of genes having some possible functions, and the authors have experimentally validated them.

Tissue-specific functional networks for prioritizing phenotype and disease genes.
November 8, 2012Large-scale genomic datasets can easily be transformed into various networks. The authors aimed to infer for each particular edge, whether or not it shows up in a particular tissue by training a model based on well curated tissue-specific expression as gold standards. The algorithm arrives at different tissue-specific networks from large-scale genomics datasets; without surprise, tissue-specific networks are more informative in predicting genes corresponding to diseases related to that particular tissue. For instance, a
testis-specific network performs better in predicting genes associated with male fertility phenotypes.

Aneuploidy prediction and tumor classification with heterogeneous hidden conditional random fields.
November 5, 2012This paper introduces a new method for detecting copy number variants in cancer genomes that addresses deficiencies of previous detection methods. The new method, dubbed HHCRF by the authors, adds the use of sequential correlations in selecting classification features for inferring copy numbers and identifying clinically relevant genes. This improvement results in higher accuracy on noisy data, and the identification of more clinically relevant genes, relative to previous methods. These results were obtained by testing HHCRF on both simulated array-CGH microarray data, and on actual breast cancer, uveal melanoma, and bladder tumor datasets.

October 20, 2012From XJM:
A few references about nonsynonymous/synonymous ratio in Cancer: Here is a Nature paper finding nonsynonymous/synonymous ratio to be 3:1 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2712719/
Here is an article reporting the ratio to be about 4:1
