hsa-mir-1972: Hsa-mir-1972 is a microRNA that has been implicated in the regulation of gene expression in various pathological conditions. It has been shown to target and inhibit the expression of BAIAP3 in vitro, suggesting a role in cellular processes that BAIAP3 may influence [PMC7906144]. In a study comparing patients with Common Variable Immunodeficiency (CVID) before and after treatment, hsa-mir-1972 was among the microRNAs with significant expression changes, indicating its potential involvement in the immune response or disease progression [PMC7722869]. Additionally, hsa-mir-1972 is involved in regulating THSD4, a down-regulated gene according to a DEmiRNA-DEmRNA interaction network analysis, which may have implications for understanding its role in disease mechanisms [PMC8799076]. In the context of leukoaraiosis (LA), hsa-mir-1972 was significantly altered and associated with up-regulated mRNAs within white matter lesion (WML) tissue, suggesting its involvement in LA pathogenesis [PMC7906144]. Furthermore, lower plasma levels of hsa-mir-1972 have been confirmed by quantitative PCR in patients with type I LA compared to controls without LA [PMC7906144]. Lastly, hsa-mir-1972 was found to be downregulated among patients with ankylosing spondylitis (AS), which supports its potential as a biomarker for disease progression and understanding disease targets and factors [PMC7795580].
