Abstract
Circular RNA (circRNA), a new type of endogenous non-coding RNA, is abundantly present in eukaryotic cells, and characterized as stable high conservation and tissue specific expression. It has been generated increasing attention because of their close association with the progress of diseases. The liver is the vital organ of humans, while it is prone to acute and chronic diseases due to the influence of multiple pathogenic factors. Moreover, hepatocellular carcinoma (HCC) is the one of most common cancer and the leading cause of cancer death worldwide. Overwhelming evidences indicate that some circRNAs are differentially expressed in liver diseases, such as, HCC, chronic hepatitis B, hepatic steatosis and hepatoblastoma tissues, etc. Additionally, these circRNAs are related to proliferation, invasion, migration, angiogenesis, apoptosis, and metastasis of cell in liver diseases and act as oncogenic agents or suppressors, and linked to clinical manifestations. In this review, we briefly summarize the biogenesis, characterization and biological functions, recent detection and identification technologies of circRNA, and regulation network mechanism of circRNA in liver diseases, and discuss their potential values as biomarkers or therapeutic targets for liver diseases, especially on HCC.

SOX Transcription Factors as Important Regulators of Neuronal and Glial Differentiation During Nervous System Development and Adult Neurogenesis. Front Mol Neurosci 2021; 14:654031. [PMID: 33867936 PMCID: PMC8044450 DOI: 10.3389/fnmol.2021.654031] [Citation(s) in RCA: 60] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Accepted: 03/11/2021] [Indexed: 12/11/2022] Open
Abstract
The SOX proteins belong to the superfamily of transcription factors (TFs) that display properties of both classical TFs and architectural components of chromatin. Since the cloning of the Sox/SOX genes, remarkable progress has been made in illuminating their roles as key players in the regulation of multiple developmental and physiological processes. SOX TFs govern diverse cellular processes during development, such as maintaining the pluripotency of stem cells, cell proliferation, cell fate decisions/germ layer formation as well as terminal cell differentiation into tissues and organs. However, their roles are not limited to development since SOX proteins influence survival, regeneration, cell death and control homeostasis in adult tissues. This review summarized current knowledge of the roles of SOX proteins in control of central nervous system development. Some SOX TFs suspend neural progenitors in proliferative, stem-like state and prevent their differentiation. SOX proteins function as pioneer factors that occupy silenced target genes and keep them in a poised state for activation at subsequent stages of differentiation. At appropriate stage of development, SOX members that maintain stemness are down-regulated in cells that are competent to differentiate, while other SOX members take over their functions and govern the process of differentiation. Distinct SOX members determine down-stream processes of neuronal and glial differentiation. Thus, sequentially acting SOX TFs orchestrate neural lineage development defining neuronal and glial phenotypes. In line with their crucial roles in the nervous system development, deregulation of specific SOX proteins activities is associated with neurodevelopmental disorders (NDDs). The overview of the current knowledge about the link between SOX gene variants and NDDs is presented. We outline the roles of SOX TFs in adult neurogenesis and brain homeostasis and discuss whether impaired adult neurogenesis, detected in neurodegenerative diseases, could be associated with deregulation of SOX proteins activities. We present the current data regarding the interaction between SOX proteins and signaling pathways and microRNAs that play roles in nervous system development. Finally, future research directions that will improve the knowledge about distinct and various roles of SOX TFs in health and diseases are presented and discussed.

Exp Mol Pathol 2020; 114:104430. [PMID: 32240614 DOI: 10.1016/j.yexmp.2020.104430] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 12/21/2019] [Accepted: 03/28/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Hypoxia/reoxygenation (H/R) injury of cardiomyocytes causes an irreversible damage to heart and largely results in acute myocardial infarction. Study has indicated lncRNA ROR aggravates myocardial ischemia/reperfusion (I/R) injury. Also, lncRNA ROR sponges miR-138 to promote osteogenesis. MiR-138 involves in hypoxic pulmonary vascular remodelling by targeting Mst1. However, the interaction between lncRNA ROR, miR-138 and Mst1 involved in myocardial H/R injury is still unknown. METHODS H9C2 cells were used to establish H/R injury model. The expression levels of lncRNA ROR and miR-138 were modified by transfection with the miR-138 mimics or lncRNA ROR overexpression plasmid. MTT and flow cytometry analysis were performed to detect cell proliferation and apoptosis. Dual luciferase reporter assay was used to determine interaction between lncRNA ROR and miR-138 or miR-138 and Mst1. Expression levels of lncRNA ROR, miR-138, Mst1 and apoptosis-related markers were determined by qRT-PCR or western blotting. RESULTS LncRNA ROR was significantly up-regulated, while miR-138 was obviously down-regulated in H/R-induced injury of H9C2 cells. Furthermore, miR-138 overexpression alleviated cardiac cell apoptosis induced by H/R injury. Mst1 was revealed to be a target of miR-138 and negatively regulated by miR-138. Mst1 overexpression reversed the protective effects of miR-138 on H/R injury of H9C2 cells. LncRNA ROR was identified as a sponge for miR-138. MiR-138 could protect H9C2 cells form H/R injury induced by lncRNA ROR overexpression. CONCLUSION Our study provides that lncRNA ROR sponges miR-138 to aggravate H/R-induced myocardial cell injury by upregulating the expression of Mst1.

Down-regulation of MBNL1-AS1 contributes to tumorigenesis of NSCLC via sponging miR-135a-5p. Biomed Pharmacother 2020; 125:109856. [PMID: 32092823 DOI: 10.1016/j.biopha.2020.109856] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Revised: 12/11/2019] [Accepted: 12/13/2019] [Indexed: 02/07/2023] Open
Abstract
Lung cancer remains a big threat to human health. Growing evidence has reported the crucial regulatory effect of lncRNAs on NSCLC progression. Nevertheless, the detailed function of lncRNA MBNL1-AS1 involved in NSCLC development is poorly known. In our research, we confirmed that MBNL1-AS1 was significantly reduced in NSCLC patient tissues and NSCLC cells. Meanwhile, we reported that overexpression of MBNL1-AS1 obviously repressed A549 and H1975 cell proliferation, blocked cell cycle and inhibited the migration and invasion. Moreover, A549 and H1975 cell apoptosis was increased by the overexpression of MBNL1-AS1. Then, we predicted that miR-135a-5p was a potential target of MBNL1-AS1 and its level was correlated with MBNL1-AS1 in NSCLC negatively. Our previous study indicated miR-135a-5p could induce lung cancer progression through regulating LOXL4. Here, we found that MBNL1-AS1 was able to regulate miR-135a-5p expression negatively. The direct binding association between MBNL1-AS1 and miR-135a-5p was proved using dual-luciferase reporter assay and RIP experiment. Subcutaneous xenotransplanted tumor model was set up and it was confirmed increased MBNL1-AS1 remarkably restrained tumorigenic ability of NSCLC through sponging miR-135a-5p in vivo. To sum up, our data revealed the significance of the MBNL1-AS1 and miR-135a-5p in NSCLC. In conclusion, MBNL1-AS1 could be a new therapeutic target to treat NSCLC.

MicroRNA-129-5p alleviates nerve injury and inflammatory response of Alzheimer's disease via downregulating SOX6. Cell Cycle 2019; 18:3095-3110.

Abstract
There is growing evidence of the position of microRNAs (miRs) in Alzheimer's disease (AD), thus our objective was to discuss the impact of miR-129-5p regulating nerve injury and inflammatory response in AD rats by modulating SOX6 expression. The AD rat model was established by injecting Aβ25-35 into the brain. The pathological changes, ultrastructure, number of neurons, cell degeneration and apoptosis of hippocampal tissue were observed in vivo. MiR-129-5p, SOX6, IL-1β, TNF-α, Bcl-2 and Bax expression in serum and hippocampal tissues were detected by ELISA, RT-qPCR or western blot analysis. The successfully modeled hippocampal neuronal cells of AD were transfected with miR-129-5p mimic, SOX6-siRNA or their controls to figure out their roles in proliferation, apoptosis and inflammatory reaction in vitro. Low expression of SOX6 and high expression of miR-129-5p in vivo of rats would shorten the escape latent period and increase the times of crossing platforms, alleviate the pathological injury, inhibit neuronal apoptosis and reduce the inflammatory reaction. Up-regulation of miR-129-5p and down-regulation of SOX6 promoted proliferation, suppressed apoptosis and degraded the inflammatory reaction of neuronal cells in vitro. Up-regulation of SOX6 reversed the expression of miR-129-5p to reduce the damage and inflammatory response of the cell model of AD. Our study presents that up-regulation of miR-129-5p or down-regulation of SOX6 can reduce nerve injury and inflammatory response in rats with AD. Thus, miR-129-5p may be a potential candidate for the treatment of AD.
