Recent accumulating researches implicate that non-coding RNAs (ncRNAs) including microRNA (miRNA), circular RNA (circRNA), and long non-coding RNA (lncRNAs) play crucial roles in colorectal cancer (CRC) initiation and development. Notably, N6-methyladenosine (m6A) methylation, the critical posttranscriptional modulators, exerts various functions in ncRNA metabolism such as stability and degradation. However, the interaction regulation network among ncRNAs and the interplay with m6A-related regulators has not been well documented, particularly in CRC. Here, we summarize the interaction networks and sub-networks of ncRNAs in CRC based on a data-driven approach from the publications (IF > 6) in the last quinquennium (2016–2021). Further, we extend the regulatory pattern between the core m6A regulators and m6A-related ncRNAs in the context of CRC metastasis and progression. Thus, our review will highlight the clinical potential of ncRNAs and m6A modifiers as promising biomarkers and therapeutic targets for improving the diagnostic precision and treatment of CRC.

AbstractBackgroundRecent studies demonstrated that long non-coding RNAs (lncRNAs) were involved in many biological processes. Dysregulated lncRNAs are related to many cancers, including colorectal cancer (CRC). However, the molecular mechanism of lncRNA ZEB1-AS1 in CRC is not clear.MethodsLncRNA ZEB1-AS1, miR-205, and YAP1 expression were measured by quantitative reverse transcriptase PCR (QRT-PCR). YAP1 protein expression was measured by western blotting. Cell viability was measured by MTT assay. Cell apoptosis was detected by flow cytometry. Luciferase reporter assay was used to confirm the relationship between ZEB1-AS1, miR-205, and YAP1.ResultsLncRNA ZEB1-AS1 and YAP1 was upregulated in CRC tissues. The expression of YAP1 was positively correlated with ZEB1-AS1. Knockdown of ZEB1-AS1 inhibited cell viability and induced apoptosis in CRC cell line SW480 and HCT116 which could be reversed by overexpression of YAP1. ZEB1-AS1 targeted and regulated miR-205 which could directly bind to YAP1. Meanwhile, ZEB1-AS1 regulated the expression of YAP1 via modulating miR-205.ConclusionLong non-coding RNA ZEB1-AS1 silencing could inhibit cell proliferation and induce apoptosis of colorectal cancer via regulating miR-205 and YAP1.

Root-knot nematodes (RKNs) severely affect plants growth and productivity, and several commercial biocontrol bacteria can improve plants resistance to RKNs. Pseudomonas putida Sneb821 isolate was found to induce tomatoes resistance against Meloidogyne incognita. However, the molecular functions behind induced resistance remains unclear. Long non-coding RNA (lncRNA) is considered to be a new component that regulates the molecular functions of plant immunity. We found lncRNA was involved in Sneb821-induced tomato resistance to M. incognita. Compared with tomato inoculated with M. incognita, high-throughput sequencing showed that 43 lncRNAs were upregulated, while 35 lncRNAs were downregulated in tomatoes previously inoculated with Sneb821. A regulation network of lncRNAs was constructed, and the results indicated that 12 lncRNAs were found to act as sponges of their corresponding miRNAs. By using qRT-PCR and the overexpression vector pBI121, we found the expression of lncRNA44664 correlated with miR396/GRFs (growth-regulating factors) and lncRNA48734 was correlated with miR156/SPL (squamosal promoter-binding protein-like) transcription factors. These observations provided a novel molecular model in biocontrol bacteria-induced tomato resistance to M. incognita.

Circular RNA (circRNAs) belong to the long non-coding RNA family, but unlike the linear RNA in circular RNA, the 3’ and 5’ end in the RNA molecule are joined together, forming their circular structure. Until recently, circRNAs have been believed to be a side product of splicing, but now it is known that they have a wide range of biological functions, from regulators of gene expression to regulators of other non-coding RNAs - microRNAs (miRNAs). CircRNAs have the potential of being therapeutic targets and biomarkers for diseases. There are little data and only several investigations about this type of RNAs in myocardial infarction in humans. This review summarizes the role of some new circRNA – miRNA interactions in the development of Myocardial Infarction.

Long non-coding RNAs (lncRNAs) have been shown to participate in the development and progression of several different types of cancer. Past studies indicated that lncRNA MAFG-antisense 1 (AS1) promotes colorectal cancer. However, the role of MAFG-AS1 in hepatocellular carcinoma (HCC) remains unclear. The aim of the present study is to examine the effect of lncRNA MAFG-AS1 on drug resistance HCC. The results indicated that MAFG-AS1 is upregulated in drug-resistant cells. Further, MAFG-AS1 promotes growth and migration of HCC by upregulating STRN4 through absorbing miR-3196. Thus, LncRNA MAFA-AS1 may become a novel target to treat HCC patients.

Long non-coding RNAs (lncRNAs) are widely transcribed in the genome, but their expression profile and roles in colorectal cancer are not well understood. The aim of this study was to investigate the long non-coding RNA expression profile in colorectal cancer and look for potential diagnostic biomarkers of colorectal cancer. Long non-coding RNA microarray was applied to investigate the global long non-coding RNA expression profile in colorectal cancer. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses were performed using standard enrichment computational methods. The expression levels of selected long non-coding RNAs were validated by quantitative reverse transcription polymerase chain reaction. The relationship between long non-coding RNA expression levels and clinicopathological characteristics of colorectal cancer patients was assessed. Coexpression analyses were carried out to find the coexpressed genes of differentially expressed long non-coding RNAs, followed by gene ontology analysis to predict the possible role of the selected long non-coding RNAs in colorectal carcinogenesis. In this study, a total of 1596 long non-coding RNA transcripts and 1866 messenger RNA transcripts were dysregulated in tumor tissues compared with paired normal tissues. The top upregulated long non-coding RNAs in tumor tissues were CCAT1, UCA1, RP5-881L22.5, NOS2P3, and BC005081 and the top downregulated long non-coding RNAs were AK055386, AC078941.1, RP4-800J21.3, RP11-628E19.3, and RP11-384P7.7. Long non-coding RNA UCA1 was significantly upregulated in colon cancer, and AK055386 was significantly downregulated in tumor with dimension <5 cm. Functional prediction analyses showed that both the long non-coding RNAs coexpress with cell cycle related messenger RNAs. The current long non-coding RNA study provided novel insights into expression profile in colorectal cancer and predicted the potential roles of long non-coding RNAs in colorectal carcinogenesis. Among the dysregulated long non-coding RNAs, UCA1 was found to be associated with anatomic site, and AK055386 was found associated with tumor size. Further functional investigations into the molecular mechanisms are warranted to clarify the role of long non-coding RNA in colorectal carcinogenesis.

N6-methyladenosine (m6A) is the most common epigenetic modification of eukaryotic RNA, which can participate in the growth and development of the body and a variety of physiological and disease processes by affecting the splicing, processing, localization, transport, translation, and degradation of RNA. Increasing evidence shows that non-coding RNAs, particularly microRNA, long non-coding RNA, and circular RNA, can also regulate the RNA m6A modification process by affecting the expression of m6A-related enzymes. The interaction between m6A modification and non-coding RNAs provides a new perspective for the exploration of the potential mechanism of tumor genesis and development. In this review, we summarize the potential mechanisms and effects of m6A and non-coding RNAs in gastrointestinal tract cancers.

Myocardial infarction is one of the major causes of mortality worldwide and is a main cause of heart failure. This disease appears as a final point of atherosclerotic plaque progression, destabilization, and rupture. As a consequence of cardiomyocytes death during the infarction, the heart undergoes unfavorable cardiac remodeling, which results in its failure. Therefore, therapies aimed to limit the processes of atherosclerotic plaque progression, cardiac damage during the infarction, and subsequent remodeling are urgently warranted. A hopeful therapeutic option for the future medicine is targeting and regulating non-coding RNA (ncRNA), like microRNA, circular RNA (circRNA), or long non-coding RNA (lncRNA). In this review, the approaches targeted at ncRNAs participating in the aforementioned pathophysiological processes involved in myocardial infarction and their outcomes in preclinical studies have been concisely presented.
