The only commercial miRNA qPCR system, the TaqMan® miRNA assay from Applied Biosystems, uses the stem-loop RT technique. This method requires one specific RT primer for each miRNA of interest. The miRNA specific primers are added to the reaction mixture after the RT reaction, but before the PCR. The qPCR is performed using the TaqMan® MiRNA Assay and TaqMan® Universal PCR Master Mix with the TaqMan® miRNA assay. The relative miRNA expression is calculated based on the cycle threshold (Ct) difference between the target miRNA and the endogenous control RNU48. This method has been used in many different applications and is considered the gold standard in miRNA qPCR [12], [13]. The major advantage of this method is the use of a universal PCR primer that ensures that the specific product is detected.
Total RNA extraction, cDNA synthesis, and real-time PCR analyses.
Total RNA was extracted from 1 ml of amniotic fluid using the TriPure Isolation Reagent (Roche Diagnostics) and the quality and quantity was determined using a NanoDrop ND-1000 Spectrophotometer (NanoDrop Technologies, Wilmington, DE).
In summary, we present FungiQuant, a comprehensive broad-coverage tool for the quantification of fungal abundance by real-time PCR. It provides a qualitative and quantitative view of the fungal microbiome in environmental samples. This tool is based on a SYBR Green detection system which is more sensitive than other methods for determining fungal abundance.
We downloaded the CpG Island data of Human Liver cancer from GEO (accession number GSE14520). The data were then used to obtain the MSKCC Liver CpG Island Methylation Data. The fraction of methylated reads relative to the total reads was recorded. The fraction were then normalized to the total read coverage of the sequencing data.
We downloaded the Whole Exome Sequencing data of Mouse Bxpc-3 gallbladder cancer from NCBI (accession number GSE18279). The data were then used to obtain the MSKCC Bxpc-3 somatic mutation data. For each mutation type, the fraction of mutated reads relative to the total reads were recorded. The fractions were then normalized to the total read coverage of the sequencing data.
Bacterial 16S rRNA quantitative PCR. 16S rRNA gene copies per reaction were quantified in 92 maternal plasma samples from non-smokers with the same extraction and qPCR protocol as the original study [6]. Statistical significance was determined by Mann-Whitney test. ns, non-significant
Bacterial 16S rRNA quantitative PCR. 16S rRNA gene copies per reaction were quantified in 53 amniotic fluid samples collected from pregnant women without bacterial vaginosis (BV) in the original study [6]. Statistical significance was determined by Mann-Whitney test. ns, non-significant 827ec27edc
