When eukaryotic cells are deprived of amino acids, uncharged tRNAs accumulate and activate the conserved GCN2 protein kinase. We examine how yeast growth and tRNA charging or aminoacylation is affected during amino acid depletion in the presence and absence of GCN2. tRNA charging is measured using ...
ORGANISM(S): Saccharomyces cerevisiae 
To better understand the extent to which induced pluripotent stem cells (iPSCs) faithfully recapitulate the characteristics of embryonic stem cells (ESCs) under (undiff)erentiated condition, KSR condition and FBS condition and how both compare to somatic tissues under these conditions, we employed w...
ORGANISM(S): Homo sapiens 
To broaden the appeal of the NIH Stem Cell Database, we analyzed a subset of undifferentiated human embryonic stem cell lines (5 lines in duplicate) on the Affymetrix platform. One standard culture protocol was used in conjunction with rigorous quality control. Expanded description of methods used a...

Original description of the study: From ELLIPSE (linked to the PRACTICAL consortium), we contributed ~78,000 SNPs to the OncoArray. A large fraction of the content was derived from the GWAS meta-analyses in European ancestry populations (overall and aggressive disease; ~27K SNPs). We also ...
