Identification of HIV1-specific cascaded microRNA-mRNA regulatory relationships by parallel mRNA and microRNA expression profiling with AIDS patients after antiviral treatment


ABSTRACT: The molecular pathogenesis of infection by HIV (human immunodeficiency virus) is extremely complex and is not clearly defined despite intensive research efforts. MiRNA as a class of regulators in cancer development can affect multiple gene pathways by targeting various mRNAs. Thus, studies aimed at transcription and regulation after antiviral treatment combined with beneficial researches related to miRNAs are required. With the purpose of identifying the cascaded miRNA-mRNA regulatory relationships related to infection of HIV in gene level, the parallel miRNA and mRNA expression profiles were analyzed in our study. The differential expressed miRNAs and mRNAs were selected primarily. The differentially regulated miRNA-mRNA interactions were further identified according to the Pearson correlation analysis of gene expression level. In our study, the calculation of the regulatory impact factors (RIF) was also conducted, and it revealed several essential regulators related to antiviral treatment with AIDS. To give a further insight into these TF (transcription factors) regulators, the co-expression gene modules were identified using a threshold-based hierarchical clustering method. Meanwhile, the regulatory network was generated during the computing process. Understanding these regulatory elements may bear significant implications on understanding the pathogenesis of AIDS occurrence.
