We have analyzed the abundance of mRNAs expressed from 11 nuclear genes in leaves of a free-growing aspen (Populus tremula) tree throughout the growing season. We used multivariate statistics to determine the influence of environmental factors (i.e. the weather before sampling) and developmental responses to seasonal changes at the mRNA level for each of these genes. The gene encoding a germin-like protein was only expressed early in the season, whereas the other tested genes were expressed t...

Environmental Effects on Gene Expression Phenotype Have Regional Biases in the Human Genome
Genetics ; ABSTRACT Phenotypic discordance between monozygotic twins, such as a difference in disease susceptibility, implicates the role of the environment in determining phenotype. To assess genomewide environmental effects on "gene expression phenotype," we employed a published microarray data set for
Noninvasive Monitoring of Target Gene Expression by Imaging Reporter Gene Expression in Living Animals Using Improved Bicistronic Vectors
The Journal of Nuclear Medicine ; Indirect, noninvasive imaging of therapeutic gene expression based on levels of reporter gene expression is a powerful tool to devise improved therapeutic strategies in cancer gene therapy. The use of bicistronic vectors carrying internal ribosome entry sites (IRESs) allows the coexpression of
Gene expression: better tools: more complex results.(Cover story)
Bioscience Technology ; Gene expression has become a mainstream technique in biology, medicine, and drug development. Broadly speaking, gene expression comes in two flavors: analytical and functional. The former refers to detecting and quantifying genes, especially by comparing two samples (treated/untreated,
Tackling High Variability in Gene Expression Studies.
Genomics and Proteomics ; By Juan Pedro Steibel, Steven P. Suchyta, and Guilherme J. M. Rosa High variability in gene expression studies often prevents differences from being noticed. To increase power and improve precision of such experiments, special attention should be given to each source of variation functioning in the
