MIR1251: MIR1251 is a non-coding RNA that has been implicated in various biological processes, including lung cancer, cell migration, and invasion [PMC9288379]. It is not in strong linkage disequilibrium (LD) with the nearby microRNAs MIR135A2 [PMC8718598]. MIR1251 has been found to be associated with spontaneous preterm birth (sPTB) along with other miRNAs such as MIR4266, MIR601, and MIR3612 [PMC9884789]. It is also located within a 1-MB range of tsRMST but knockdown of tsRMST did not affect the expression of MIR1251 or other neighboring genes and microRNAs [PMC3875859]. Additionally, it has been identified as a miRNA host transcript for the miRNA MIR135A2 [PMC2926783]. Furthermore, in a study investigating genes surviving the threshold for suggestive significance after correction for multiple testing, the gene MIR1251 was found to be among those that met the threshold [PMC8169753]. In summary, MIR1251 is a non-coding RNA that has been implicated in lung cancer progression and cell migration and invasion. It is not strongly linked to nearby microRNAs such as MIR135A2. Additionally, it has been associated with spontaneous preterm birth and identified as a host transcript for another miRNA. Furthermore, it was found to meet the threshold for suggestive significance in gene expression studies.
