Scenario: A research project in Beijing on the gut microbial community of children with Autism Spectrum Disorder (ASD) aimed to screen differentially expressed bacterial genera through sequencing technology and evaluate the efficacy of probiotic therapy by observing changes in differential expression.
Requirements: For fecal samples, researchers needed a method for dynamically detecting changes in the absolute expression levels of specific genes to evaluate the intervention effect of probiotics, and explore the clinical efficacy of new therapies combined with children's behavioral scores.
Solution:
Researchers screened differentially expressed genes from 16S sequencing results, extracted nucleic acid from children's fecal samples using ArchiPure32, used high-sensitivity qPCR premix provided by Rocgene, and verified the probiotic intervention results in children with Archimed R6's relative quantification (double standard curve method).
Results:
Relative quantification (double standard curve method) results can not only accurately evaluate the content of different bacterial genera in each sample, but also reflect changes in the relative expression values of different bacterial genera. Combined with children's behavioral scores, it accurately reflects the impact of probiotics on children with autism. It also demonstrates the important value of Rocgene series instruments in the validation of gene expression quantification in microbiology-related research.
