[5] Peripheral blood mononuclear cell (PBMC) miRNA expression has been studied as potential biomarker for different neurological disorders such as Parkinson's disease,[8] Multiple sclerosis.
[9] Evaluating small RNA is useful for certain kinds of study because its molecules "do not need to be fragmented prior to library preparation".
[3]: 162 Types of small RNA include: The first known function in plants was discovered in mutants of Arabidopsis.
Specifically with decline in function mutations for RNA-dependent RNA polymerase and DICER-like production.
Altogether this demonstrates great dependence of nematode parasitism on plants' own small RNAs.
