And Function

Given the crucial role of microRNAs in the cellular proliferation of various types of cancers, we aimed to analyze the expression and function of a cellular proliferation-associated miR-188-5p in papillary thyroid carcinoma (PTC). Here we demonstrate that miR-188-5p is downregulated in PTC tumor tissues compared with the associated noncancerous tissues. We also validate that the miR-188-5p overexpression suppressed the PTC cancer cell proliferation. In addition, fibroblast growth factor 5 (FGF5) is observed to be downregulated in the PTC tumor tissues compared with the associated noncancerous tissues. Subsequently, FGF5 is identified as the direct functional target of miR-188-5p. Moreover, the silencing of FGF5 was found to inhibit PTC cell proliferation, which is the same pattern as miR-188-5p overexpression. These results suggest that miR-188-5p-associated silencing of FGF5 inhibits tumor cell proliferation in PTC. It also highlights the importance of further evaluating miR-188-5p as a potential biomarker and therapy target in PTC.

Background: Papillary thyroid carcinoma (PTC) is a subtype of thyroid cancer with increasing incidence over time. Objective: This study aimed to build a risk score (RS) system for PTC patients. Methods: PTC microRNA (miRNA) and messenger RNA (mRNA) expression data were extracted from The Cancer Genome Atlas (TCGA) database. The 491 PTC samples were randomly divided into training and validation sets. Using the limma software package, differentially expressed mRNAs (DEGs) and miRNAs (DEMs) between the tumor and control groups were screened. In order to construct an RS system, a survival package was used to select independent miRNAs related to prognosis. Enrichment analysis was performed, and a miRNA-mRNA co-expression network was constructed. High-throughput sequencing was also used to verify the prognostic miRNAs in exosomes. Results: We found 1363 DEGs and 171 DEMs between the tumor and control groups. After identifying 26 DEMs that were significantly related to prognosis, 6 independent prognosis-associated miRNAs were selected to build an RS system. The areas under the curves of the overall survival rates of the training, validation, and entire sets were 0.847, 0.772, and 0.819, respectively. By conducting pathway analysis using the miRNA-mRNA co-expression network, one overlapping factor and five overlapping pathways were obtained. In addition, high-throughput sequencing revealed that the hsa-miR-129-2, hsa-miR-548j, hsa-miR-6734, and hsa-miR-889 expression levels in TCGA tumor tissues and exosomes were consistent, and those of hsa-miR-129-2 and hsa-miR-889 between patients and controls were significantly different in exosomes. Conclusion: The six-miRNA RS system in exosomes may comprise independent signatures for predicting PTC patient prognosis.

Abstract Background: Circular RNA (circRNA) has been reported to play multiple roles in a variety of cancers. However, the role of circRNA in papillary thyroid carcinoma (PTC) remains mostly unknown. Methods: The expression, function and potential molecular mechanisms of hsa_circ_0000839 in PTC in vitro were evaluated by quantitative RT-PCR, western blot, flow cytometry, CCK8, Edu, RNA-sequencing, luciferase reporter, and RNA immunoprecipitation assay. The function of hsa_circ_0000839 in PTC in vivo was evaluated by xenograft tumors assay.Results: Hsa_circ_0000839 was significantly downregulated in PTC tissues and plasma from patients with PTC, and its downregulation was correlated with larger tumor size in patients with PTC. The role of hsa_circ_0000839 in the proliferation of PTC cell lines was evaluated in both vitro and in vivo. Mechanistically, hsa_circ_0000839 regulated the level of CDC27 via sponging miR-149-5p in PTC. Conclusions: Hsa_circ_0000839 might act as a tumor suppressor of PTC through the hsa_circ_0000839/miR-149-5p/CDC27 axis. Hsa_circ_0000839 could serve as a potential biomarker and therapeutic target for patients with PTC.

<b><i>Introduction:</i></b> Papillary thyroid microcarcinoma (PTMC) is a specific subgroup of papillary thyroid carcinoma and defined with the dimension ≤1 cm by the WHO. Although it shows a relatively high 10-year livability, the metastasis of PTMC into other tissues and organs seriously affects the daily life of patients with relatively high mortality. Therefore, the genetic basis for the metastasis of PTMC needs to be explored for effective therapeutic targets. Here, we conducted a series of comparative analysis of the transcriptional expression profile between PTMC patients with and without lymph node metastasis. <b><i>Methods:</i></b> Gene expression profile and gene function were analyzed using RNA extracted from pathological tissues of 12 patients with PTMC, and the core biomarkers closely related to its metastasis were identified. <b><i>Results:</i></b> Our results showed that 7,507 genes and 42 RNAs showed remarkably different expression patterns. More sophisticated analysis showed that the high expression of 2 lncRNAs (T077499 and T004533) resulted in the metastasis of PTMC, which suggests that the expression pattern of the 2 lncRNAs may act as a potential biomarker for pathogenesis and prognosis of PTMC metastasis. <b><i>Conclusion:</i></b> Our findings preliminarily reveal the molecular mechanisms for PTMC metastasis, which will provide vital reference for subsequent studies about the genetic basis and molecular targeted therapy for PTMC metastasis.
