Abstract

Objective: Infection with herpes simplex virus type 1 induces viral latency in neuron trigeminal ganglions. The late associated transcript (LAT) is uniquely expressed in infected neural cells, however no coding protein associated with these transcripts has been identified in infected cells. It has been shown that six MICRORNAS transcribed from LAT have the capabilities to affect the cell signaling pathways, thus interfering in pathways such as those of cell differentiation and proliferation. Transforming growth factor beta (TGF-b) pathway is a critical pathway among cell signaling circuits. The SMAD4 PROTEIN, as an important member of the TGF-b signaling pathway, mediates the connection between membrane receptors, cytoplasmic kinases, and nuclear transcription factors.Methods: This study bioinformatically and experimentally evaluated LAT microRNA expression and assessed microRNA targeting of Smad4 transcripts in human neuroblastoma cells by using real-time PCR.Results: Analysis of two different software results showed that the Smad4 gene was targeted by LAT-derived MICRORNAS at multiple sites. Over-expression of LAT MICRORNAS in BE2(c) cells caused reduction in Smad4 transcripts.Conclusion: The results of bioinformatical analysis with relative quantification of Smad4 transcripts and its downstream-related genes such as cyclinD, CDK2, and Myc showed that the LAT transcript could control Smad4 expression.
