bmo-mir-3000: bmo-mir-3000 is a microRNA (miRNA) that has been observed to play a role in the host response to bacterial infection, specifically showing differential expression patterns during infections with Listeria species [PMC5733040]. This miRNA was found to be upregulated in the presence of the pathogenic L. monocytogenes, while it was downregulated when infected with the non-pathogenic L. innocua [PMC5733040]. The upregulation of bmo-mir-3000 during L. monocytogenes infection suggests an active involvement in the host's defensive mechanisms, potentially through the targeting of specific genes such as chitotriosidase-1 [PMC5733040]. The expression patterns of bmo-mir-3000 were found to be in strong agreement with microarray results, reinforcing its significance in response to infection [PMC5733040]. Moreover, quantitative real-time PCR has validated these findings, confirming bmo-mir-3000's role and its reciprocal regulation depending on the pathogenicity of the infecting Listeria strain [PMC5733040]. The inverse expression profile of bmo-mir-3000 during infections with different Listeria species highlights its potential as a biomarker for distinguishing between pathogenic and non-pathogenic infections [PMC5733040].
