From these results, the original assembly file produced by Trinity was filtered to remove transcripts that represent less than 5% of the RSEM based expression level of its parent unigene or transcripts with transcripts per million (TPM) value below 0.5.
Among the array-based expression levels of 365 miRNAs, only the 228 miRNAs that were detectable in ≥ 30% of the samples of either the preterm infants or adults were included for subsequent analyses.
To verify that the observed differences in gene expression are true transcriptional differences, Affymetrix data-based expression levels of specific markers for T cells, macrophages, dendritic cells and granulocytes were checked.
For the qRT-PCR data analysis, differentially expressed genes in response to EGF and HRG stimulation were searched for by calculating the index I, defined as follows; where x t, EGF and x t, HRG represent qRT-PCR-based expression levels of gene x after t hours administration of EGF and HRG, respectively.
Based on these findings, a clinical trial for anti-PD1 (pembrolizumab) was conducted where NSCLC patients were screened based on expression levels of PD-L1 on the primary tumor7,14.
A diagnostic model based on expression levels of ten miRNAs is constructed in the discovery set.
Based on expression levels of the top-ranked genes, we chose Col4a1/a2, encoding the alpha-1 or alpha-2 chain of type IV collagen, for the reporter gene in our shRNA screening (Figs 1A and S1B).
Alternatively, autosomal genes may regulate imprinting based on expression levels of heterosomal genes.
There was minimal mesoderm or neuroectoderm formation based on expression levels of the markers brachyury and Sox1, respectively.
