Summary of the Study
MicroRNAs (miRNAs) are small noncoding RNAs that attenuate expression of their mRNA targets. Here, we developed a new method and an R package to infer candidate miRNA–mRNA target interactions that could be functional during a given biological process.
Using this method, we described, for the first time, a comprehensive integrated analysis of miRNAs and mRNAs during human normal plasma cell differentiation (PCD). Our results reveal:
- 63 miRNAs with significant temporal changes during normal PCD
- A high-confidence network of 295 target relationships involving 47 miRNAs and 141 mRNAs
- New regulatory links, including miR-30b/c/d targeting IRF4, PRDM1, ELL2, ARID3A
- 24 miRNAs overexpressed in multiple myeloma (MM) that overlap with normal PCD regulators
This study identifies candidate novel key miRNAs regulating both normal PCD and malignant plasma cell biology.
