摘要:

Studies on coding genes, miRNAs, and lncRNAs during erythroid development have been performed in recent years. However, analysis focusing on the integration of the three RNA types has yet to be done. In the present study, we compared the dynamics of coding genes, miRNA, and lncRNA expression profiles. To explore dynamic changes in erythropoiesis and potential mechanisms that control these changes in the transcriptome level, we took advantage of high throughput sequencing technologies to obtain transcriptome data from cord blood hematopoietic stem cells and the following four erythroid differentiation stages, as well as from mature red blood cells. Results indicated that lncRNAs were promising cell marker candidates for erythroid differentiation. Clustering analysis classified the differentially expressed genes into four subtypes that corresponded to dynamic changes during stemness maintenance, mid-differentiation, and maturation. Integrated analysis revealed that noncoding RNAs potentially participated in controlling blood cell maturation, and especially associated with heme metabolism and responses to oxygen species and DNA damage. These regulatory interactions were displayed in a comprehensive network, thereby inferring correlations between RNAs and their associated functions. These data provided a substantial resource for the study of normal erythropoiesis, which will permit further investigation and understanding of erythroid development and acquired erythroid disorders.

Paternal environmental exposure-induced spermatozoal small noncoding RNA alteration meditates the intergenerational

《医学前沿(英文)》 2022年 第16卷 第2期   页码 176-184 doi: 10.1007/s11684-021-0885-y

摘要: Studies of human and mammalian have revealed that environmental exposure can affect paternal health conditions as well as those of the offspring. However, studies that explore the mechanisms that meditate this transmission are rare. Recently, small noncoding RNAs (sncRNAs) in sperm have seemed crucial to this transmission due to their alteration in sperm in response to environmental exposure, and the methodology of microinjection of isolated total RNA or sncRNAs or synthetically identified sncRNAs gradually lifted the veil of sncRNA regulation during intergenerational inheritance along the male line. Hence, by reviewing relevant literature, this study intends to answer the following research concepts: (1) paternal environmental factors that can be passed on to offspring and are attributed to spermatozoal sncRNAs, (2) potential role of paternal spermatozoal sncRNAs during the intergenerational inheritance process, and (3) the potential mechanism by which spermatozoal sncRNAs meditate intergenerational inheritance. In summary, increased attention highlights the hidden wonder of spermatozoal sncRNAs during intergenerational inheritance. Therefore, in the future, more studies should focus on the origin of RNA alteration, the target of RNA regulation, and how sncRNA regulation during embryonic development can be sustained even in adult offspring.

The critical importance of epigenetics in autoimmune-related skin diseases

《医学前沿(英文)》 2023年 第17卷 第1期   页码 43-57 doi: 10.1007/s11684-022-0980-8

摘要: Autoimmune-related skin diseases are a group of disorders with diverse etiology and pathophysiology involved in autoimmunity. Genetics and environmental factors may contribute to the development of these autoimmune disorders. Although the etiology and pathogenesis of these disorders are poorly understood, environmental variables that induce aberrant epigenetic regulations may provide some insights. Epigenetics is the study of heritable mechanisms that regulate gene expression without changing DNA sequences. The most important epigenetic mechanisms are DNA methylation, histone modification, and noncoding RNAs. In this review, we discuss the most recent findings regarding the function of epigenetic mechanisms in autoimmune-related skin disorders, including systemic lupus erythematosus, bullous skin diseases, psoriasis, and systemic sclerosis. These findings will expand our understanding and highlight the possible clinical applications of precision epigenetics approaches.

摘要:

组织工程是医学科学中一个相对较新但发展迅速的领域。非编码RNA(ncRNA) 是不编码蛋白质的功能性RNA 分子,它们可以调节细胞的行为、改变组织的生物学环境。虽然以对ncRNA 作为治疗靶点尚未进入临床实践,但ncRNA 在组织工程中的应用已经吸引了越来越多的关注,而且对ncRNA 的调节作用和释放方法的深入探讨可以促进其在组织工程中的应用。本文简要介绍了ncRNA 在神经、皮肤、肝脏、血管和肌肉的调控作用和可能的释放方法及其潜在的治疗应用价值。

Accurate quantification of 3′-terminal 2′-O-methylated small RNAs by utilizing oxidative deep sequencing

《医学前沿(英文)》 2022年 第16卷 第2期   页码 240-250 doi: 10.1007/s11684-021-0909-7

摘要: The continuing discoveries of novel classes of RNA modifications in various organisms have raised the need for improving sensitive, convenient, and reliable methods for quantifying RNA modifications. In particular, a subset of small RNAs, including microRNAs (miRNAs) and Piwi-interacting RNAs (piRNAs), are modified at their 3′-terminal nucleotides via 2′-O-methylation. However, quantifying the levels of these small RNAs is difficult because 2′-O-methylation at the RNA 3′-terminus inhibits the activity of polyadenylate polymerase and T4 RNA ligase. These two enzymes are indispensable for RNA labeling or ligation in conventional miRNA quantification assays. In this study, we profiled 3′-terminal 2′-O-methyl plant miRNAs in the livers of rice-fed mice by oxidative deep sequencing and detected increasing amounts of plant miRNAs with prolonged oxidation treatment. We further compared the efficiency of stem-loop and poly(A)-tailed RT-qPCR in quantifying plant miRNAs in animal tissues and identified stem-loop RT-qPCR as the only suitable approach. Likewise, stem-loop RT-qPCR was superior to poly(A)-tailed RT-qPCR in quantifying 3′-terminal 2′-O-methyl piRNAs in human seminal plasma. In summary, this study established a standard procedure for quantifying the levels of 3′-terminal 2′-O-methyl miRNAs in plants and piRNAs. Accurate measurement of the 3′-terminal 2′-O-methylation of small RNAs has profound implications for understanding their pathophysiologic roles in biological systems.

摘要: Alternative splicing is a tightly regulated process that contributes to cancer development. CRNDE is a long noncoding RNA with alternative splicing and is implicated in the pathogenesis of several cancers. However, whether deregulated expression of CRNDE is common and which isoforms are mainly involved in cancers remain unclear. In this study, we report that CRNDE is aberrantly expressed in the majority of solid and hematopoietic malignancies. The investigation of CRNDE expression in normal samples revealed that CRNDE was expressed in a tissue- and cell-specific manner. Further comparison of CRNDE expression in 2938 patient samples from 15 solid and hematopoietic tumors showed that CRNDE was significantly overexpressed in 11 malignancies, including 3 reported and 8 unreported, and also implicated that the overexpressed isoforms differed in various cancer types. Furthermore, anti-cancer drugs could efficiently repress CRNDE overexpression in cancer cell lines and primary samples, and even had different impacts on the expression of CRNDE isoforms. Finally, experimental profiles of 12 alternatively spliced isoforms demonstrated that the spliced variant CRNDE-g was the most highly expressed isoform in multiple cancer types. Collectively, our results emphasize the cancer-associated feature of CRNDE and its spliced isoforms, and may provide promising targets for cancer diagnosis and therapy.

Long noncoding RNA LOC646029 functions as a ceRNA to suppress ovarian cancer progression through the

摘要: Long noncoding RNAs (lncRNAs) play a crucial regulatory role in the development and progression of multiple cancers. However, the potential mechanism by which lncRNAs affect the recurrence and metastasis of ovarian cancer remains unclear. In the current study, the lncRNA LOC646029 was markedly downregulated in metastatic ovarian tumors compared with primary tumors. Gain- and loss-of-function assays demonstrated that LOC646029 inhibits the proliferation, invasiveness, and metastasis of ovarian cancer cells in vivo and in vitro. Moreover, the downregulation of LOC646029 in metastatic ovarian tumors was strongly correlated with poor prognosis. Mechanistically, LOC646029 served as a miR-627-3p sponge to promote the expression of Sprouty-related EVH1 domain-containing protein 1, which is necessary for suppressing tumor metastasis and inhibiting KRAS signaling. Collectively, our results demonstrated that LOC646029 is involved in the progression and metastasis of ovarian cancer, which may be a potential prognostic biomarker.
