Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?

Dme-mir-283 is a highly upregulated miRNA in fly cells following alphavirus infection, regardless of the presence of Wolbachia [PMC8402854]. In silico miRNA prediction suggests that dme-mir-283 has the potential to target the 3' untranslated region (3'UTR) of the DmDNMT2 gene [PMC8402854]. It is assumed that dme-mir-283 downregulates DmDNMT2 expression, which is consistent with the expression pattern of this miRNA and its target in adult flies [PMC8402854]. The expression profile of dme-mir-283 does not correlate with dme-mir-304 and dme-mir-12, but there is a correlation between dme-mir-304 and dme-mir-12 [PMC3150300]. Additionally, there is no correlation between dme-mir-283* and either dme-mir-283 itself or other miRNAs in its cluster [PMC3150300]. The expression profiles of several other miRNAs, including dme-mir-100, dme-mir-992, and dme-mir-306, also have low correlation coefficients with profiles of their corresponding miRNAs* [PMC3150300]. Furthermore, the expression profiles of several other miRNAs such as dme-miR305 and 100 have weak correlations with at least one miRNA from their respective clusters [PMC3150300].
