"Transcriptional profiles" refer to the unique patterns of gene expression or activity in a cell. It reveals which genes are being turned on or off at a particular time or under certain conditions. Full definition
The study looked at transcriptional profiles of 247 tissue samples from six humans, five chimps, and five macaques. (seeker.com)
Isolating both the genomic DNA and RNA from such cells allows researchers to develop complete transcriptional profiles from the liquid biopsy. (sciencemag.org)
To conduct the experiments, the team will use state of the art genome engineering technology to generate mutant embryonic stem cells at a large scale, followed by transcriptional profiling via next generation sequencing. (vds-molecules-of-life.org)
