hsa-mir-4270: The expression of hsa-mir-4270 was found to be the most affected by hsa_circ_0005556 [PMC7521983]. However, there were no concordant patterns between qRT-PCR and microarrays for hsa-mir-4270 [PMC4658123]. Hsa-mir-4270, along with other miRNAs such as hsa-miR-4462, hsa-miR-3622b-5p, hsa-miR-6088, and hsa-miR-3934-5p, were found to be involved in ADM [PMC9978013]. Hsa-mir-4270 was also identified as a potential Exo-miRNA [PMC8104147]. Hsa-mir-4270 was significantly upregulated in patients' samples compared to controls and may have a role in cancer stage [PMC4867432]. Hsa-mir-4270 was predicted to be a common regulator of ACE, ACE2, and TMPRSS2 in the context of SARS-CoV-2 infection [PMC9511898]. Hsa-mir-4270 was among the circulating miRNAs identified in breast cancer patients [PMC8573223]. In sepsis-induced AKI groups, hsa-mir 4270 was upregulated while miRNAs such as hsa-miR 142 5p and hsa miR 22 3p were downregulated compared to healthy controls [PMC5351858]. HSA mir 4270 along with other miRNAs were found to target BCAS4 and SHISA7 genes associated with AD-related neurofibrillary pathology [PMC8899724]. In leiomyoma compared to myometrium samples, mir 4270 expression levels were downregulated [PMC9154092].
