US cancer institute to overhaul tumour cell lines

July 9, 2017

QT:{{"
“The NCI will continue to supply the NCI-60 cell lines to researchers, but will eventually refocus its drug screening on newer models. It is developing hundreds of ‘patient-derived xenografts’ (PDXs), which are created by implanting small chunks of human tumours into mice. There, the tumours grow in an environment that, although not human, better mimics their native environment”

Inferring chromatin-bound protein complexes from genome-wide binding assays – Genome Research

Inferring [w. NMF] chromatin-bound protein complexes [of TFs] from [ENCODE ChIP-seq] binding assays, by @ElementoLab

Giannopoulou E, Elemento O. 2013. Inferring chromatin-bound
protein complexes from genome-wide binding assays. Genome Research, Published in Advance April 3, 2013, doi: 10.1101/gr.149419.112.

This study uses nonnegative matrix factorization (NMF) of ENCODE CHIP-seq data (transcription
factors and histone modifications) to predict complexes of
transcription factors that bind DNA
together; it then assesses how these predicted complexes regulate gene expression. It goes beyond
previous studies in that it attempts to treat the TFs as complexes rather than individuals. A handful of
the predicted complexes correspond to known regulatory complexes, e.g. PRC2, and overall, the
complexes were enriched for known protein-protein interactions. Linear regression and random forest
models were then used to predict the effects of the complexes on the expression of adjacent genes. In
both models, the complexes performed better than those predicted from a scrambled TF read count
matrix. Overall, this study provides a large set of hypotheses for combinations of TFs that may
function together, as well as potential new components of known complexes.
