Liu Q, Zhao H, Guo Y, Zhang K, Shang F, Liu T. Bioinformatics-Based Analysis: Noncoding RNA-Mediated COL10A1 Is Associated with Poor Prognosis and Immune Cell Infiltration in Pancreatic Cancer. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:7904982. [PMID: 36105715 PMCID: PMC9467764 DOI: 10.1155/2022/7904982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/26/2022] [Accepted: 07/28/2022] [Indexed: 11/17/2022]
Abstract
Background Collagen type X alpha 1 (COL10A1) is a structural component of the extracellular matrix that is aberrantly expressed in a variety of cancer tissues. However, its role in pancreatic cancer progression is not well understood. Methods The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), and Gene Expression Profiling Interaction Analysis (GEPIA) data were employed to explore the expression of COL10A1 in normal and tumor tissues and its prognostic value in pancreatic adenocarcinoma. The clinical data of pancreatic cancer in TCGA were used to explore the relationship between COL10A1 and clinical features. Genes coexpressed with COL10A1 were explored using multiple databases and analyzed for functional enrichment. In addition, the lncRNA/miRNA/COL10A1 axis that may be involved in COL10A1 regulation in pancreatic cancer was explored by constructing a competitive endogenous RNA (ceRNA) regulatory axis. Finally, COL10A1 was analyzed for correlation with immune cell infiltration and various immune checkpoint molecules in pancreatic cancer. Results It was found that the expression of COL10A1 was significantly increased in pancreatic cancer tissues. High expression of COL10A1 was related to the clinicopathological characteristics and the worse prognosis of pancreatic cancer patients. The TUG1/miR-144-3p/COL10A1 axis was identified as the most likely upstream noncoding RNA pathway for COL10A1 in pancreatic cancer. Besides, in pancreatic adenocarcinoma, the expression level of COL10A1 showed a significant positive correlation with tumor immune cell infiltration, biomarkers of immune cells, and expression of immune checkpoint molecules. Conclusion COL10A1 is an early diagnostic marker, and its high expression correlates with immune infiltration in pancreatic cancer. The TUG1/miR-144-3p/COL10A1 axis was identified as the most likely upstream noncoding RNA pathway for COL10A1 in pancreatic cancer.

Cheng S, Wang W. Analysis of the subcellular location of FAM230B and its interaction with premature miR-302b in osteosarcoma. J Bone Miner Metab 2022; 40:554-560. [PMID: 35639175 DOI: 10.1007/s00774-022-01319-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Accepted: 02/15/2022] [Indexed: 11/26/2022]
Abstract
INTRODUCTION FAM230B has been characterized as an oncogenic lncRNA in papillary thyroid cancer and gastric cancer, while its role in osteosarcoma (OS) is unclear. This research was conducted to analyze the interaction between FAM230B and miR-302b in OS. MATERIALS AND METHODS Paired OS and non-tumor tissues donated by 58 OS patients were subjected to RNA preparation and RT-qPCR to quantify the expression of FAM230B and miR-302b (both mature and premature). The subcellular location of FAM230B and its interaction with premature miR-320b were analyzed by cellular fractionation assay and RNA pull-down assay, respectively. The roles of FAM230B and miR-302b in OS cell movement were evaluated using Transwell assay. RESULTS Increased FAM230B and premature miR-302b and decreased mature miR-302b were observed in OS. FAM230B was detected in both nuclear and cytoplasm samples and directly interacted with premature miR-302b. FAM230B overexpression in OS cells 143B and HOS decreased miR-302b maturation and increased cell invasion and migration, while miR-302b overexpression suppressed cell invasion and migration. FAM230B silencing restrained cell invasion and migration, and miR-302b inhibitor accelerated cell invasion and migration. MiR-302b knockdown significantly reversed the suppressive effects of shFAM230B on migration and invasion of 143B and HOS cells. CONCLUSION FAM230B is accumulated to high levels in OS and may serve as an endogenous competing RNA for premature miR-302b in the nucleus to promote OS cell invasion and migration.

Abstract
Pancreatic cancer (PC) is a highly malignant disease characterized by insidious onset, rapid progress, and poor therapeutic effects. The molecular mechanisms associated with PC initiation and progression are largely insufficient, hampering the exploitation of novel diagnostic biomarkers and development of efficient therapeutic strategies. Emerging evidence recently reveals that noncoding RNAs (ncRNAs), including long ncRNAs (lncRNAs) and microRNAs (miRNAs), extensively participate in PC pathogenesis. Specifically, lncRNAs can function as competing endogenous RNAs (ceRNAs), competitively sequestering miRNAs, therefore modulating the expression levels of their downstream target genes. Such complex lncRNA/miRNA/mRNA networks, namely, ceRNA networks, play crucial roles in the biological processes of PC by regulating cell growth and survival, epithelial-mesenchymal transition and metastasis, cancer stem cell maintenance, metabolism, autophagy, chemoresistance, and angiogenesis. In this review, the emerging knowledge on the lncRNA-associated ceRNA networks involved in PC initiation and progression will be summarized, and the potentials of the competitive crosstalk as diagnostic, prognostic, and therapeutic targets will be comprehensively discussed.
