Abstract
Stomach adenocarcinoma (STAD) patients are often associated with significantly high mortality rates and poor prognoses worldwide. Among STAD patients, competing endogenous RNAs (ceRNAs) play key roles in regulating one another at the post-transcriptional stage by competing for shared miRNAs. In this study, we aimed to elucidate the roles of lncRNAs in the ceRNA network of STAD, uncovering the molecular biomarkers for target therapy and prognosis. Specifically, a multitude of differentially expressed lncRNAs, miRNAs, and mRNAs (i.e., 898 samples in total) was collected and processed from TCGA. Cytoplasmic lncRNAs were kept for evaluating overall survival (OS) time and constructing the ceRNA network. Differentially expressed mRNAs in the ceRNA network were also investigated for functional and pathological insights. Interestingly, we identified one ceRNA network including 13 lncRNAs, 25 miRNAs, and 9 mRNAs. Among them, 13 RNAs were found related to the patient survival time; their individual risk score can be adopted for prognosis inference. Finally, we constructed a comprehensive ceRNA regulatory network for STAD and developed our own risk-scoring system that can predict the OS time of STAD patients by taking into account the above.

Abstract
Colorectal cancer (CRC) is one of the most common malignant tumors, and most patients have a poor prognosis. Many studies have shown that the Hippo signaling pathway plays a key role in the occurrence and development of CRC by regulating CRC cell proliferation and apoptosis, tumor invasion and metastasis, autophagy, metabolic reprogramming, drug resistance, and other processes. This article reviews the latest progress in research of the expression of key molecules of the Hippo signaling pathway in CRC as well as the understanding of the mechanism by which this pathway regulates the occurrence and development of CRC.

Abstract
Long noncoding RNAs are master regulators of several cancer phenotypes, such as cell growth, apoptosis, and motility. This study is designed to resolve the relevance of LINC00657 with tumor invasion and migration and its action mechanism in colorectal carcinoma (CRC). LINC00657 and HPSE levels were first examined in cancerous tissues from CRC patients and CRC cells. Then functional experiments were conducted to evaluate the abilities of HCT116 and SW620 cells to proliferate, migrate, and invade when LINC00657 or HPSE was knocked down, or LINC00657 knockdown and SMAD2 overexpression were simultaneously introduced. Snail and E-cadherin levels in the CRC cells were evaluated. Next, the binding between LINC00657 and SMAD2 or between SMAD2 and HPSE was determined. LINC00657-silencing HCT116 cells were inoculated into nude mice, and the tumorigenesis and the levels of Snail and E-cadherin were evaluated. LINC00657 and HPSE were increasingly expressed in CRC. Knockdown of LINC00657 or HPSE inhibited the malignant properties of CRC cells, decreased Snail expression, and strengthened E-cadherin level. LINC00657 and HPSE could both bind to SMAD2. SMAD2 overexpression counteracted the inhibiting effect of LINC00657 silencing on HPSE expression and the growth and invasion of CRC cells. In vivo experiments further verified the suppression of LINC00657 knockdown on tumor growth and metastasis. LINC00657 recruits SMAD2 to HPSE promoter region to elevate HPSE transcription, thus accelerating CRC invasion and migration.

DNA Methylation Profiling of Human Hepatocarcinogenesis. Hepatology 2021; 74:183-199. [PMID: 33237575 PMCID: PMC8144238 DOI: 10.1002/hep.31659] [Citation(s) in RCA: 52] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Revised: 10/28/2020] [Accepted: 10/30/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND AND AIMS Mutations in TERT (telomerase reverse transcriptase) promoter are established gatekeepers in early hepatocarcinogenesis, but little is known about other molecular alterations driving this process. Epigenetic deregulation is a critical event in early malignancies. Thus, we aimed to (1) analyze DNA methylation changes during the transition from preneoplastic lesions to early HCC (eHCC) and identify candidate epigenetic gatekeepers, and to (2) assess the prognostic potential of methylation changes in cirrhotic tissue. APPROACH AND RESULTS Methylome profiling was performed using Illumina HumanMethylation450 (485,000 cytosine-phosphateguanine, 96% of known cytosine-phosphateguanine islands), with data available for a total of 390 samples: 16 healthy liver, 139 cirrhotic tissue, 8 dysplastic nodules, and 227 HCC samples, including 40 eHCC below 2cm. A phylo-epigenetic tree derived from the Euclidean distances between differentially DNA-methylated sites (n = 421,997) revealed a gradient of methylation changes spanning healthy liver, cirrhotic tissue, dysplastic nodules, and HCC with closest proximity of dysplasia to HCC. Focusing on promoter regions, we identified epigenetic gatekeeper candidates with an increasing proportion of hypermethylated samples (beta value > 0.5) from cirrhotic tissue (<1%), to dysplastic nodules (≥25%), to eHCC (≥50%), and confirmed inverse correlation between DNA methylation and gene expression for TSPYL5 (testis-specific Y-encoded-like protein 5), KCNA3 (potassium voltage-gated channel, shaker-related subfamily, member 3), LDHB (lactate dehydrogenase B), and SPINT2 (serine peptidase inhibitor, Kunitz type 2) (all P < 0.001). Unsupervised clustering of genome-wide methylation profiles of cirrhotic tissue identified two clusters, M1 and M2, with 42% and 58% of patients, respectively, which correlates with survival (P < 0.05), independent of etiology. CONCLUSIONS Genome-wide DNA-methylation profiles accurately discriminate the different histological stages of human hepatocarcinogenesis. We report on epigenetic gatekeepers in the transition between dysplastic nodules and eHCC. DNA-methylation changes in cirrhotic tissue correlate with clinical outcomes.

Abstract
Bladder cancer (BC), as one of the most common cancers around the world, begins in the inner side of the bladder and is inclined to spread to the remaining parts of the body. Extensive documents have shown that long noncoding RNAs function as stimuli in various cancer types. With regard to LINC00649, there is limited investigation on its role previously. In our research, we discovered that LINC00649 was considerably highly expressed in BC cells and the lack of LINC00649 would cause inactivity in cellular proliferation, migration, and invasion. miR-16-5p turned out to be competitively incorporated by LINC00649 in the upstream or JARID2 downstream. In BC cells, LINC00649 was found to bind with miR-16-5p to increase the expression of JARID2. Overly expressed JARID2 was found to reverse the LINC00649 shortage-mediated suppressive impacts on the cellular process of BC cells. Concisely, it was the first study on the molecular mechanism of LINC00649 in BC. This work detected that LINC00649 enhanced cell proliferation, migration, and invasion of BC cells by acting as a sponge of miR-16-5p and upregulating JARID2, providing novel insight into understating BC.

Abstract
Colorectal cancer (CRC) is one of the most common gastrointestinal cancers, with extremely high rates of morbidity and mortality. The main cause of death in CRC is distant metastasis; it affects patient prognosis and survival and is one of the key challenges in the treatment of CRC. Long non-coding RNAs (lncRNAs) are a group of non-coding RNA molecules with more than 200 nucleotides. Abnormal lncRNA expression is closely related to the occurrence and progression of several diseases, including cancer. Recent studies have shown that numerous lncRNAs play pivotal roles in the CRC metastasis, and reversing the expression of these lncRNAs through artificial means can reduce the malignant phenotype of metastatic CRC to some extent. This review summarizes the major mechanisms of lncRNAs in CRC metastasis and proposes lncRNAs as potential therapeutic targets for CRC and molecular markers for early diagnosis.

Abstract
Background Bladder cancer (BLCA) refers to the malignancy growth that spreads from the bladder linings to the bladder muscles. However, the impact of miR-22-3p and lncRNA TRPM2-AS on this tumor has generated divergent views in the literature. This research aimed to study the effects of lncRNA TRPM2-AS on BLCA and its interaction with miR-22-3p and GINS2 mRNA. Methods qRT-PCR was employed to measure the expression of TRPM2-AS, miR-22-3p and GINS2 mRNA in bladder tissues and cells. The subcellular localization of TRPM2-AS in T24 and 5637 cell lines was identified using a cell fractionation system. Luciferase assay, RIP assay and RNA pull-down assay were later performed to validate the direct binding relationship between TRPM2-AS, miR-22-3p and GINS2 mRNA. Several experiments were conducted to determine the viability, proliferation, colony formation and apoptosis of the cell lines. Results Findings indicated that TRPM2-AS was significantly upregulated in BLCA tissues and cell lines. Apart from that, it was observed that TRPM2-AS knockdown significantly inhibited the viability, proliferation and colony formation of BCLA cells, but it promoted the apoptosis of the BCLA cells. A significant downstream target of TRPM2-AS, miR-22-3p was found to show a lower expression level in BLCA tissues and cell lines. However, the inhibition of miR-22-3p considerably enhanced BLCA cell phenotypes. As well as discovering that GINS2 mRNA was a downstream target of miR-22-3p and was significantly upregulated in BLCA, experimental results also indicated that the knockdown of GINS2 suppressed BLCA cell phenotypes. Conclusion This research confirmed that TRPM2-AS could promote BCLA by binding to miR-22-3p to increase GINS2 expression. This novel interactome in BLCA cell lines might provide more insights into BLCA therapy.

Abstract
Abnormal expression of long noncoding RNA (lncRNA) is involved in human cancers, including colorectal cancer (CRC). However, their functional mechanism is largely unknown. In this study, we explored the roles of lncRNA SOCS2-AS1 in modulating CRC progression. We showed that SOCS2-AS1 was lowly expressed in CRC tissues and cells. SOCS2-AS1 downregulation predicted a poor prognosis in patients with CRC. SOCS2-AS1 overexpression significantly suppressed CRC cell proliferation, colony formation, EdU incorporation, cell-cycle, migration and invasion in vitro while SOCS2-AS1 knockdown led to an opposite phenotype. SOCS2-AS1 overexpression inhibited CRC growth and metastasis in vivo. Mechanistically, we discovered that SOCS2-AS1 was positively correlated with SOCS2 expression in CRC tissues. SOCS2-AS1 contributes to SOCS2 expression through restraining miR-1264. Additionally, we showed that SOCS2 silencing abrogated the suppressive effects of SOCS2-AS1 overexpression. Taken together, our results identified a novel regulatory loop in which SOCS2-AS1/miR-1264/SOCS2 axis suppresses CRC progression.

Abstract
Background Long noncoding RNA has been involved in tumorigenesis of colorectal cancer (CRC). This study aimed to illustrate the functions and mechanisms of LINC00173 in CRC progression. Methods The expression of LINC00173 in CRC tissues and cell lines were analyzed via qRT-PCR. Kaplan-Meier curve was used to determine survival rate. Luciferase reporter assay was conducted to evaluate the interactions among LINC00173, miR-765 and PLP2 (proteolipid protein 2). CCK8 assay, EdU assay, transwell assay and xenograft assay were performed to examine the effect of LINC00173/miR-765/PLP2 axis on proliferation, migration and invasion. The Ki67 expression level in tumors tissues was detected through immunofluorescence assay. Results LINC00173 expression was markedly upregulated in CRC tissues and cells. High expression level of LINC00173 in CRC patients was correlated with poor prognosis. LINC00173 knockdown inhibited proliferation, migration, invasion and chemo-resistance of CRC cells in vitro. LINC00173 downregulation delayed CRC growth in vivo. LINC00173 interacted with miR-765 to promote PLP2 expression. Conclusion Our results demonstrated that LINC00173 plays an important oncogenic role in CRC via modulating miR-765/PLP2 axis. And LINC00173 may be a potential prognostic biomarker and therapeutic target for CRC.

Abstract
Background: Bioinformatics showed that long non-coding RNA (lncRNA) pgm5-as1 was regulated in patients with colorectal cancer (CRC), and miR-484 was also regulated in CRC. We aimed at determining the modulatory pathway of lncRNA pgm5-as1 in CRC cells, and whether miR-484 was involved in the pathway. Materials and Methods: The target gene of pgm5-as1 was predicted by bioinformatics and verified by dual luciferase assay. Transcription levels of pgm5-as1 and miR-484 were determined by quantitative real-time polymerase chain reaction. Viability, migration rate, invasion, and growth of SW480 and HCT116 cells were determined by Cell Counting Kit-8 (CCK-8), wound healing assay, transwell, and colony formation assay, respectively. Results: pgm5-as1 was upregulated in CRC tissues and cell lines; however, its downregulation contributed to the decreasing of cell viability, growth, migration, and invasion of SW480 and HCT116 cells. Moreover, miR-484 was predicted as the target of pgm5-as1, and the downregulation of pgm5-as1 partially restored the elevated cell viability, growth, migration, and invasion that were induced by the inhibition of miR-484 expression in SW480 and HCT116 cells. Conclusions: The loss of miR-484 expression in CRC might be involved in the promotion and metastasis of CRC, which may be caused by the overexpression of pgm5-as1. Hence, the downregulation of pgm5-as1 could be a therapeutic target in the prevention or intervention of CRC.

Abstract
Objective: Long non-coding RNAs (lncRNAs) are critical to colorectal cancer (CRC) progression. In the current study, the objective was the exploration of the role played by lncRNA MIR4435-2HG in CRC proliferation and metastasis. Methods: lncRNA MIR4435-2HG expression and its association with CRC were analyzed using database and clinical specimens. The influences exerted by MIR4435-2HG on cell proliferating process, invading process, and migrating process of CRC were identified after MIR4435-2HG knockdown. The influences exerted by MIR4435-2HG on tumor growth and metastasis were assessed in vivo. The underlying mechanistic associations between MIR4435-2HG, microRNA miR-206, and the transcription factor Yes-associated protein 1 (YAP1) were assessed using bioinformatics and a luciferase reporter gene assay. Results: MIR4435-2HG was highly expressed in CRC tissue in contrast with that in regular tissues and displayed relations to poor prognosis. MIR4435-2HG knockdown could suppress CRC cell proliferation, invasion, and migration. Moreover, MIR4435-2HG knockdown inhibited CRC growth and liver metastasis in vitro. We found MIR4435-2HG knockdown reduced YAP1, CTGF, AREG, vimentin, Snail, Slug, and Twist expression but enhanced E-cadherin expression. Functionally, MIR4435-2HG acted as a competing endogenous RNA (ceRNA) to upregulate YAP1 by sponging miR-206. Conclusions: MIR4435-2HG promoted CRC growth and metastasis through miR-206/YAP1 axis and is likely to play prognostic marker roles and be therapeutically targeted in CRC.

Long noncoding RNA AC114812.8 promotes the progression of bladder cancer through miR-371b-5p/FUT4 axis. Biomed Pharmacother 2019; 121:109605. [PMID: 31706102 DOI: 10.1016/j.biopha.2019.109605] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Revised: 10/20/2019] [Accepted: 10/26/2019] [Indexed: 12/27/2022] Open
Abstract
Bladder cancer (BC) brings a heavy burden to afflicted patients worldwide. In order to find new diagnostic markers and therapeutic targets for this disease, we investigated the role of a novel lncRNA, AC114812.8, in bladder cancer progression. Clone formation and CCK-8 assays were used to detect the proliferative capacity of the cells, and the transwell assay was used to explore their invasion and migration abilities. Wound healing experiments were also used to detect cell migration. Luciferase reporter assays were used to investigate the interactions between lncRNA, target gene and miRNA. The expression of FUT4 and marker genes related to epithelial-mesenchymal transition was explored through western blot analysis. Our findings revealed that AC114812.8 was significantly upregulated in BC and could markedly facilitate the proliferation, migration, and invasion of bladder cancer cells both in vitro and in vivo. Furthermore, duel-luciferase reporter assay revealed that AC114812.8 could regulate the FUT4 expression level by sponging miR-371b-5p to facilitate BC progression. We detected the levels of EMT-related biomarkers in AC114812.8-overexpressing BC cells by western blot analysis and found that AC114812.8 could promote EMT process. Rescue experiments showed that miR-371b-5p could rescue the effect of AC114812.8 on proliferation and metastasis of BC. Our results suggest that AC114812.8 could be a novel prognostic biomarker and therapeutic target for bladder cancer.

Front Oncol 2019; 9:1008.

Abstract
Colorectal cancer (CRC) is a common malignancy with 1. 8 million cases in 2018. Autophagy helps to maintain an adequate cancer microenvironment in order to provide nutritional supplement under adverse conditions such as starvation and hypoxia. Additionally, most of the cases of CRC are unresponsive to chemotherapy, representing a significant challenge for cancer therapy. Recently, autophagy induced by therapy has been shown as a unique mechanism of resistance to anticancer drugs. In this regard, long non-coding RNAs (lncRNAs) analysis are important for cancer detection, progression, diagnosis, therapy response, and prognostic values. With increasing development of quantitative detection techniques, lncRNAs derived from patients' non-invasive samples (i.e., blood, stools, and urine) has become into a novel approach in precision oncology. Tumorspecific GAS5, HOTAIR, H19, and MALAT are novels CRC related lncRNAs detected in patients. Nonetheless, the effect and mechanism of lncRNAs in cancer autophagy and chemoresistance have not been extensively characterized. Chemoresistance and autophagy are relevant for cancer treatment and lncRNAs play a pivotal role in resistance acquisition for several drugs. LncRNAs such as HAGLROS, KCNQ1OT1, and H19 are examples of lncRNAs related to chemoresistance leaded by autophagy. Finally, clinical implications of lncRNAs in CRC are relevant, since they have been associated with tumor differentiation, tumor size, histological grade, histological types, Dukes staging, degree of differentiation, lymph node metastasis, distant metastasis, recurrent free survival, and overall survival (OS).

Abstract
Background Long noncoding RNAs (lncRNAs) have been reported to be associated with the proliferation of several cancer cells. The aim of this study was to investigate the role of FLVCR1-AS1 in ovarian serous cancer (OSC). Methods FLVCR1-AS1 expression was determined in human OSC tissues, serums and cell lines. The role of FLVCR1-AS1 knockdown or overexpression on OSC cell growth, migration, invasion, apoptosis and epithelial to mesenchymal transition (EMT) were evaluated in vitro using CCK8, colony formation assay, wound healing assay, transwell assay and western blot assay. Besides, luciferase reporter assays were performed to identify interactions among FLVCR1-AS1 and its target genes. Moreover, the in vivo effects were investigated using immunocompromised NSG female mice. Results In this study, FLVCR1-AS1 expression was upregulated in OSC tissues, serums, and cells. Knockdown FLVCR1-AS1 decreased cell growth, migration, invasion, and EMT, as well as increased apoptosis in OSC cells, whereas, overexpression of FLVCR1-AS1 increased cell proliferation, migration, invasion, and EMT, and decreased apoptosis of OSC cells. Besides, FLVCR1-AS1 directly bound to miR-513 and downregulated its expression. Moreover, FLVCR1-AS1 reversed the effect of miR-513 on the OSC cell growth, which might be associated with the role of YAP1. Furthermore, in terms of mechanism, FLVCR1-AS1 promoted EMT in OSC cells. Finally, mice models further confirmed that knockdown FLVCR1-AS1 distinctly suppressed cell growth and EMT in vivo. Conclusion Taken together, FLVCR1-AS1 mediated miR-513/YAP1 signaling to promote cell progression, migration, invasion and EMT process in OSC cells.

Abstract
Introduction: It has been reported that long noncoding RNAs (lncRNAs) are crucial regulators in progression of human cancers, including colorectal cancer (CRC). However, the function of lncRNA ARAP1 antisense RNA 1 (ARAP1-AS1) in CRC remains unclear. Aim: The aim of this study was to investigate the function and molecular mechanism of lncRNA ARAP1-AS1 in CRC. Results: ARAP1-AS1 was highly expressed in CRC tissues and cell lines. ARAP1-AS1 knockdown suppressed cell migration, invasion, and epithelial-mesenchymal transition (EMT). YY1 transcription factor (YY1) enhanced the transcription activity of ARAP1-AS1. The YY1/ARAP1-AS1 axis promoted CRC cell migration and invasion. YY1/ARAP1-AS1 could regulate the Wnt/β-catenin signaling pathway. Conclusions: This study revealed that YY1-induced upregulation of ARAP1-AS1 promoted cell migration, invasion, and EMT process in CRC through the Wnt/β-catenin signaling pathway.

Abstract
The antibody era has greatly impacted cancer management in recent decades. Indeed, antibodies are currently applied for both cancer diagnosis and therapy. For example, monoclonal antibodies are the main constituents of several in vitro diagnostics, which are applied at many levels of cancer diagnosis. Moreover, the great improvement provided by in vivo imaging, especially for early-stage cancer diagnosis, has traced the path for the development of a complete new class of antibodies, i.e., engineered antibody fragments. The latter embody the optimal characteristics (e.g., low renal retention, rapid clearance, and small size) which make them ideal for in vivo applications. Furthermore, the present review focuses on reviewing the main applications of antibodies and antibody fragments for solid cancer diagnosis, both in vitro and in vivo. Furthermore, we review the scientific evidence showing that ion channels represent an almost unexplored class of ideal targets for both in vitro and in vivo diagnostic purposes. In particular, we review the applications, in solid cancers, of monoclonal antibodies and engineered antibody fragments targeting the voltage-dependent ion channel Kv 11.1, also known as hERG1.
