The phrase "a previous study on the transcriptomic" is correct and usable in written English.
It can be used when referring to an earlier research work that focuses on transcriptomics, which is the study of RNA transcripts in a cell or organism.
Example: "In light of the findings from a previous study on the transcriptomic, we decided to explore the gene expression patterns further."
Alternatives: "an earlier study on transcriptomics" or "a prior investigation into transcriptomic analysis".
In a previous study that aimed to determine the effect of various cosmetic treatments on barrier function we performed a transcriptomic analysis of epidermis in addition to TEWL measurements [ 13].
This is in contrast to a previous study where, following ALS inhibitor application, no transcriptomic changes were observed in plants resistant because of a mutant herbicide-resistant ALS, while their sensitive counterparts showed extensive transcriptomic changes [ 33].
Genome-wide transcriptomic profiles of eight green fluorescent protein (GFP -marked cell populations with 2–3 replicates each were obtained, that in combination with a previous study of 11 microarray expression experiments yielded a transcriptomic expression atlas.
Most previous studies on transcriptomic signatures of insect diapause compared the nondiapausing insects to diapausing individuals in which the diapause syndrome was already fully expressed in the phase of diapause maintenance [ 29– 39].
The discrepancies observed between results of this transcriptomic study and a previous proteomic study on the same material revealed post-transcriptional mechanisms of regulation of expression of genes encoding cell wall proteins.
Moreover previous study on pig secretome [ 5, 26] and data obtained in rodent suggested that much less transcriptomic units might exist than anatomical separations imply.
Previous studies based on transcriptomic profiling indicate the significance of several ROS regulators to act as the initial trigger communicating downstream defense signals [ 16].
The importance of cysteine proteases in leaf proteolysis is in agreement with previous studies on winter oilseed rape demonstrating that the cysteine protease SAG12 is highly induced at the transcriptomic [ 56] and proteomic [ 31] levels during leaf senescence.
Two previous studies on cultured human cells have investigated the effect of time on transcriptomic responses to altered zinc regimes [ 30, 32].
In a previous transcriptomic study on salmon lice [ 18] gene regulation in immature and mature adult female lice was investigated.
