Long noncoding RNA (lncRNA) refers to RNA transcripts with more than 200 nucleotides in length, which plays regulatory roles directly in the form of RNA. Their functions are affected by their secondary structures, post transcriptional modification and so on. LncRNA can be classified to various subtypes with complicated mechanisms. In human-induced-pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs), dynamic expression of some lncRNAs is detected during the neuronal differentiation, and a series of lncRNAs associated closely with the development process of the central nervous system (CNS) are found. This review summarizes the molecular biological properties of lncRNA and their regulatory functions in the development of the CNS, which is helpful to reveal the mechanisms of the pathogenesis and progression of certain neurological diseases and results in innovation of their diagnosis and treatment.

Objective To evaluate the effects of geraniol(GOH) on neointima hyperplasia in rat carotid artery balloon injury model, and explore the potential molecular mechanisms associated with this effect. Methods Totally 20 male Sprague-Dawley (SD) rats were randomly divided into sham operation group (without balloon injury), control group (with balloon injury), low concentration group (with 50 mg/kg GOH intervention after balloon injury) and high concentration group (with 200 mg/kg GOH intervention after balloon injury). The intima to media (I/M) area ratio of neointima was measured by hematoxylin- eosin (HE) staining. The expression of proliferating cell nuclear antigen (PCNA) was measured by immunohistochemical staining at 14th day after operation. As the marker of oxidative stress, the levels of 8-hydroxy-2’-deoxyguanosine (8-OHdG) and malondialdehyde (MDA) were measured by enzyme linked inmmnosorbent assay (ELISA). Results The I/M ratio, IOD, 8-OHdG and MDA values were increased in control group compared with those of sham group. The I/M ratio, IOD and 8-OHdG values were reduced in low concentration group compared with those of control group. But there was no significant difference in MDA level between low concentration group and control group. The I/M ratio, IOD, 8-OHdG and MDA values were significantly reduced in high concentration group compared with those of control group, which showed a more significant inhibitory effect than that of low concentration group (P<0.05). Conclusion GOH could attenuate balloon iniury induced neointima hyperplasia, which might be related to its effect on inhibiting expression of PCNA and decreasing oxidative stress.
