A study in human preterm newborns demonstrated that the miR-345-5p was significantly up-regulated in cord blood plasma of patients with culture-positive early-onset neonatal sepsis compared to gestational age-matched controls [Janec et al. DOI:10.14712/fb2023069050173]. In a rat model of cavernous nerve injury erectile dysfunction, high-throughput sequencing identified rno-miR-345-5p_R+1 as a differentially expressed miRNA predicted to be sponged by circRNA945, which was downregulated in the disease model [Huang et al. DOI:10.1080/21655979.2021.1973863].
