mmu-mir-5100: mmu-mir-5100 is a microRNA sequence found in mouse B cells, with a notable presence on chromosome 11 [PMC4488125][PMC5595893]. It is among the miRNAs with varied expression levels, being one of the highly expressed miRNAs in certain studies, while in others, it is found to have low expression [PMC5595893][PMC3555835]. Notably, mmu-mir-5100 has been identified to have target genes such as Podxl, Rab6b, and Rab6a that are significantly downregulated in neutrophils during pneumonia; however, the expression of mmu-mir-5100 itself does not change [PMC5595893]. In studies utilizing next-generation sequencing and microarray analysis, mmu-mir-5100 has been detected as differentially expressed and upregulated under certain conditions such as LPS treatment [PMC4079956][PMC7945321]. Despite these findings on its expression and target genes, mmu-mir-5100's functional roles and implications in physiological or disease processes require further investigation to fully understand its impact on cellular processes.
