Abstract
The view of long noncoding RNAs as nonfunctional "garbage" has been definitely outdated by the large body of evidence indicating this class of ncRNAs as "golden junk", especially in precision oncology. Indeed, in light of their oncogenic role and the higher expression in multiple cancer types compared with paired adjacent tissues, the clinical interest for lncRNAs as diagnostic and/or prognostic biomarkers has been rapidly increasing. The emergence of large-scale sequencing technologies, their subsequent diffusion even in small research and clinical centers, the technological advances for the detection of low-copy lncRNAs in body fluids, coupled to the huge reduction of operating costs, have nowadays made possible to rapidly and comprehensively profile them in multiple tumors and large cohorts. In this review, we first summarize some relevant data about the oncogenic role of well-studied lncRNAs having a clinical relevance. Then, we focus on the description of their potential use as diagnostic/prognostic biomarkers, including an updated overview about licensed patents or clinical trials on lncRNAs in oncology.

Identification of fatty acid metabolism-based molecular subtypes and prognostic signature to predict immune landscape and guide clinical drug treatment in renal clear cell carcinoma. Int Immunopharmacol 2023; 116:109735. [PMID: 36716517 DOI: 10.1016/j.intimp.2023.109735] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 01/04/2023] [Accepted: 01/11/2023] [Indexed: 01/29/2023]
Abstract
Three subtypes of samples were generated based on genes involved in fatty acid metabolism in The Cancer Genome Atlas (TCGA)-RCC patients using a non-negative matrix factorization (NMF) algorithm. 32 co-expressed modules were identified using WCGNA. We constructed a four-gene signature in our training set using least absolute shrinkage selection operator regression analysis and verified it in our testing and overall sets. A relevant study analysis in clinical trials was conducted, which showed the model had good stability and potential application value for predicting outcomes. We analyzed the immune microenvironment using MCPcounter, CIBERSORT, quanTIseq, TIMER and ESTIMATE algorithms, and the result indicated risk was positively related to T cells, B-lineage, and fibroblasts and negatively correlated with monocytic lineage, myeloid dendritic cells, neutrophils, and endothelial cells, and CPT1B was positively related to T cells, CD8 + T cells, Cytotoxic lymphocytes and NK cells, and negatively correlated with myeloid dendritic cells, fibroblasts, endothelial cells. Tumor mutation burden was positively related to risk score and the expression of CPT1B using the R packages corrplot, circlize. Through the R package pRRophetic, drug sensitivity tests showed that the low-risk score group would benefit more from sunitinib and less from pazopanib, sorafenib, temsirolimus, gemcitabine and doxorubicin than the high-risk score group. We performed the relevant basic assay validation for CPT1B, and the proliferation ability of RCC cells was inhibited after the knockdown of protein expression of CPT1B. In conclusion, we established a four-gene model that can predict outcomes of RCC with potential applications in diagnosis and treatment.

Abstract
Glioblastoma is the most frequent form of malignant brain tumor. Cytoplasmic polyadenylation element binding protein 4 (CPEB4) is overexpressed and involved in the tumorigenesis and metastasis of glioblastoma. miR-130a-3p has been revealed to be aberrantly expressed in tumors and has aroused wide attention. In present study, we would like to investigate the effect and potential mechanism of miR-130a-3p on the proliferation and migration in glioblastoma. The relative expression levels of miR-130a-3p and CPEB4 in glioblastoma cell lines were detected by real-time quantitative polymerase chain reaction. Cell viability and migration were detected by methylthiazolyl tetrazolium assay and transwell assay, and cell cycle analysis was detected by flow cytometry. The expression of CPEB4 protein and epithelial-mesenchymal transition associated markers were detected by western blot. Bioinformatics and luciferase activity analysis were used to verify the targeting relationship between miR-130a-3p and CPEB4. We observed that the expression of CPEB4 was upregulated while that of miR-130a-3p was downregulated in glioblastoma cell lines. CPEB4 was validated as a target of miR-130a-3p by luciferase activity assay. Increased levels of miR-130a-3p inhibited the proliferation and migration of the glioblastoma cells and the overexpression of miR-130a-3p inhibited epithelial-mesenchymal transition. However, CPEB4 overexpression resisted the inhibitory effects of miR-130a-3p. Our study elucidates CPEB4 is upregulated because of the downregulated miR-130a-3p in glioblastoma, which enhances the glioblastoma growth and migration, suggesting a potential therapeutic target for the disease.

Abstract
BACKGROUND Circular RNAs (circRNAs) are a specific family of non-coding RNAs (ncRNAs) with important function in disease progression. This research is performed to study circRNA Ring Finger Protein 220 (circRNF220) in acute myeloid leukemia (AML). METHODS CircRNF220, microRNA-330-5p (miR-330-5p) and sex-determining region Y-related high-mobility group box 4 (SOX4) were measured via quantitative real-time polymerase chain reaction (qRT-PCR). 3-(4, 5-dimethylthiazol-2-y1)-2, 5- diphenyl tetrazolium bromide (MTT) and EdU assays were used to assess cell proliferation. Cell cycle and apoptosis were detected using flow cytometry. Cell invasion was determined by transwell assay. Glycolytic metabolism was assessed by glucose consumption and lactate production. The target interaction was implemented via dual-luciferase reporter and RNA pull-down assays. SOX4 protein detection was conducted by western blot. RESULTS Expression detection identified that circRNF220 was overexpressed in AML. In vitro experiments showed that silence of circRNF220 promoted cell apoptosis but impeded proliferation, cell cycle progression, invasion and glycolytic metabolism in AML cells. Target analysis indicated that circRNF220 directly targeted miR-330-5p, and the effects of si-circRNF220 were abrogated by miR-330-5p inhibitor. Moreover, circRNF220 targeted miR-330-5p to increase the expression of SOX4 and SOX4 promoted cell progression of AML. CONCLUSION All these findings revealed that circRNF220 contributed to AML cell development in vitro via upregulating SOX4 expression by targeting miR-330-5p.

Abstract
BACKGROUND Renal cell carcinoma (RCC) is the main aggressive subtype of kidney cancer. Circular RNAs have been shown to exert critical roles in RCC. However, little is known about the regulatory mechanism of hsa_circ_0015004 (circSDHC) in RCC. METHODS 35 patients with RCC were recruited in the research. Expression changes of circSDHC were determined by real-time quantitative polymerase chain reaction (RT-qPCR). The effects of circSDHC inhibition on cell proliferation, apoptosis, angiogenesis, migration, and invasion were analyzed. The regulation mechanism of circSDHC was surveyed by bioinformatics analysis. The effect of circSDHC on tumorigenesis was validated by xenograft assay. RESULTS We observed an observable elevation in circSDHC expression in RCC tissues and cell lines. Functionally, circSDHC silencing decreased xenograft tumor growth and induced RCC cell apoptosis, repressed RCC cell proliferation, angiogenesis, migration, and invasion in vitro. Mechanically, circSDHC modulated centrosomal protein 55 (CEP55) expression by functioning as a miR-130a-3p sponge. Also, miR-130a-3p silencing offset circSDHC knockdown-mediated impacts on malignant phenotypes and angiogenesis of RCC cells. Furthermore, exogenetic expression of CEP55 counteracted miR-130a-3p overexpression-mediated effects on malignant phenotypes and angiogenesis of RCC cells. CONCLUSION Silencing of circSDHC restrained cell malignant phenotypes and angiogenesis via reducing CEP55 expression by releasing miR-130a-3p in RCC, providing a new mechanism for understanding the progression of RCC.

Abstract
The long noncoding RNAs (lncRNAs) have been shown to actively participate in various biological processes including cancer progression. However, most lncRNAs still have undefined functions. In current work, we identified a novel lncRNA named LALTOP which displayed an oncogenic function in non-small cell lung cancer (NSCLC). LALTOP expression is increased in NSCLC tissues and cell lines. Moreover, LALTOP strongly promoted proliferation and migration of A549 and H1793 cells. RNA-RNA interaction assay showed that LALTOP bound and stabilized topoisomerase II alpha (Top2α) mRNA. Positive correlation can be found between LALTOP and Top2α mRNA expressions in clinical specimens. ASOs targeting LALTOP could markedly inhibit malignant phenotypes of NSCLC. Collectively, LALTOP may serve as an oncogenic lncRNA and enhances NSCLC progression. Targeting LALTOP has therapeutic potential for eradicating lung cancer cells.

Abstract
PURPOSE Chemoresistance remains the primary obstacle threatening the prognosis of retinoblastoma (RB). microRNAs (miRNAs) are acknowledged as critical regulators of drug resistance. This study explored the molecular mechanism of miR-130a-3p affecting the chemosensitivity of RB to vincristine (VCR). METHODS miR-130a-3p expression of human retinal astrocytes and RB cell lines (Y79, WERI-Rb-1, SO-Rb50, and SO-Rb70) was detected using RT-qPCR. VCR-resistant RB cell line Y79/VCR was induced. miR-130a-3p expression of Y79/VCR cell line and its corresponding parental cell line was detected. Y79/VCR cells were subjected to miR-130a-3p overexpression treatment. The cell proliferation was measured using MTT assay, and the IC50 value and drug resistance index were examined using CCK-8 assay. The targeting relationship between miR-130a-3p and PAX6 was predicted through bioinformatics analysis and verified using dual-luciferase assay. Functional rescue experiments were conducted to confirm the role of PAX6 in chemosensitivity of RB cells. The effect of miR-130a-3p on tumorigenesis and VCR sensitivity was observed in vivo. RESULTS miR-130a-3p was downregulated in VCR-resistant RB cells. Overexpression of miR-130a-3p repressed the proliferation of Y79/VCR cells and enhanced chemosensitivity. miR-130a-3p targeted PAX6 expression. Overexpression of PAX6 reversed the effect of miR-130a-3p on chemosensitivity of Y79/VCR cells. Overexpression of miR-130a-3p suppressed tumor growth and reduced VCR resistance in vivo. CONCLUSIONS miR-130a-3p enhanced the chemosensitivity of Y79 RB cells to VCR by targeting PAX6 expression.
