Abstract
Objective Through analyzing the SH2D5 expression profiles, clinical features, and immune infiltration in lung adenocarcinoma (LUAD), the study was intended to discuss the correlations of SH2D5 with prognosis and immune infiltration in LUAD. Methods We downloaded transcriptome and clinical data of LUAD patients from TCGA, GEO, and CCLE databases. Sangerbox, R language, GEPIA, UALCAN, and Kaplan-Meier Plotter were adopted to analyze the SH2D5 expression patterns, prognosis, and clinical features. Spearman correlation analysis was performed to determine the association between SH2D5 expression and immune cell infiltration and immune checkpoint genes. The miRNA-SH2D5 relations were predicted by miRDB and starbase. Lastly, quantitative PCR, IHC and Western blot were implemented for validation. Results A prominent up-regulation of SH2D5 was noted in the LUAD group relative to the normal group, which was validated by quantitative PCR, IHC and Western blot. SH2D5 expression was inversely related to overall survival (OS) of LUAD patients as well as B cell immune infiltration. Additionally, SH2D5 expression was negatively correlated with dendritic cells resting (p < 0.001), plasma cells (p < 0.001), mast cells resting (p = 0.031) and T cells CD4 memory resting (p = 0.036) in LUAD patients with abundant SH2D5 expression correlated with poor prognosis. Furthermore, enrichment analysis suggested that SH2D5 was associated with lung cancer and immunity. Lastly, we investigated the relationship between the expression of SH2D5 and the use of antitumor drugs. Conclusion High SH2D5 expression shares an association with unfavorable prognosis in LUAD, and SH2D5 may also provide new ideas for immunotherapy as a potential therapeutic target.

[PMID: 36175341 PMCID: PMC9530683 DOI: 10.3344/kjp.2022.35.4.423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 08/02/2022] [Accepted: 08/02/2022] [Indexed: 11/05/2022] Open
Abstract
Background The decreased expression of mu-opioid receptors (MOR) in the amygdala may be a key molecular in chronic post-surgical pain (CPSP). It is known that miR-339-5p expression in the amygdala of a stressed rat model was increased. Analyzed by RNAhybrid, miR-339-5p could target opioid receptor mu 1 (oprm1) which codes MOR directly. So, the authors hypothesized that miR-339-5p could regulate the expression of MOR via targeting oprm1 and cause the effects to CPSP. Methods To simulate perioperative short-term stress, a perioperative stress prolongs incision-induced pain hypersensitivity without changing basal pain perception rat model was built. A pmiR-RB-REPORT™ dual luciferase assay was taken to verify whether miR-339-5p could act on oprm1 as a target. The serum glucocorticoid level of rats was test. Differential expressions of MOR, GFAP, and pERK1/2 in each group of the rats' amygdala were tested, and the expressions of miR-339-5p in each group of rats' amygdalas were also measured. Results Perioperative stress prolonged the recovery time of incision pain. The expression of MOR was down-regulated in the amygdala of rats in stress + incision (S + IN) group significantly compared with other groups (P < 0.050). miR-339-5p was up-regulated in the amygdala of rats in group S + IN significantly compared with other groups (P < 0.050). miR-339-5p acts on oprm1 3'UTR and take MOR mRNA as a target. Conclusions Perioperative stress could increase the expression of miR-339-5p, and miR-339-5p could cause the expression of MOR to decrease via targeting oprm1. This regulatory pathway maybe an important molecular mechanism of CPSP.

The Expression Profile of miRNA in Glioma and the Role of miR-339-5p in Glioma. BIOMED RESEARCH INTERNATIONAL 2022; 2022:4085039. [PMID: 35782062 PMCID: PMC9242769 DOI: 10.1155/2022/4085039] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 05/22/2022] [Accepted: 05/31/2022] [Indexed: 12/26/2022]
Abstract
Objective To reveal the expression profile of miRNA in glioma and the effects of microRNA-339-5p (miR-339-5p) on glioma. Methods The glioma and normal tissues were randomly selected for miRNA gene chip detection and qRT-PCR verification. The U87 cells were separated into miR-NC, miR-339-5p mimic, and miR-339-5p suppressor group. Clonogenesis test, flow cell technique, Transwell, and cell scratch assay were utilized to verify the roles of miR-339-5p in cell proliferation, cell apoptosis, cell invasion, and cell migration. The epithelial-meso-transformation-associated proteins was verified by Western blot. Results A total of 49 miRNAs (16 upregulated and 33 downregulated) were differentially expressed in glioma tissues, and miR-339-5p was the most downregulated. The clone number, invasion number, and healing rate of cells in miR-339-5p mimic group were decreased compared with miR-NC group (P < 0.05); the clone quantity, invasion number, and healing rate of cells in miR-339-5p inhibitor group were increased compared with miR-NC group (P < 0.05). The apoptosis rate of human glioma U87 cells in miR-339-5P mimic group was compared with miR-NC group (P < 0.05); the apoptosis rate of human glioma U87 cells in miR-339-5p suppressor group decreased compared with miR-NC group (P < 0.05). Compared with miR-NC group, the protein expression of Twist, Snsnail, N-cadherin, and Vimentin in miR-339-5p mimic group was considerably decreased, whereas E-cadherin was elevated (P < 0.05). Compared with miR-NC group, the protein expression of Twist, Snsnail, N-cadherin, and Vimentin in miR-339-5p suppressor group was considerably increased, whereas E-cadherin was considerably decreased (P < 0.05). Conclusion Forty-nine glioma-related miRNAs were screened out, and miRNA expression was significantly different between glioma and normal tissues. The downregulated miR-339-5p in glioma can regulate the proliferative, apoptotic, invasive, and migratory abilities of glioma U87 cells and might suppress the occurrence and development of glioma.

COL11A1 is Downregulated by miR-339-5p and Promotes Colon Carcinoma Progression. Can J Gastroenterol Hepatol 2022; 2022:8116990. [PMID: 35669376 PMCID: PMC9167123 DOI: 10.1155/2022/8116990] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 04/28/2022] [Accepted: 05/04/2022] [Indexed: 11/18/2022] Open
Abstract
The roles of COL11A1 in cancer have been increasingly considered, but the understandings of the effects of COL11A1 on colon carcinoma progress are much limited yet. qRT-PCR and Western blot were utilized to evaluate COL11A1 expression at mRNA and protein levels, respectively, in colon carcinoma cell lines. Afterward, the tumorigenesis biological effects of COL11A1 were examined by CCK-8, colony formation, Transwell, and wound healing methods. Moreover, upstream miRNAs containing the binding sites with COL11A1 were predicted by the bioinformatics methods. The interplay between COL11A1 and miR-339-5p was identified by a dual-luciferase assay. COL11A1 expression was prominently upregulated in colon carcinoma cell lines relative to that in normal human colon mucosal epithelial cell lines, and it was related to tumor stages. The outcomes of in-vitro experiments suggested that interfering with COL11A1 remarkably repressed the malignant behaviors of SW480 and SW620 cells. MiR-339-5p was markedly lowly expressed in colon carcinoma cell lines. Furthermore, miR-339-5p directly targeted and negatively regulated COL11A1 expression. COL11A1 upregulation promoted colon carcinoma cell functions, while overexpressing miR-339-5p evidently attenuated the promotion. These results proved the modulation of the miR-339-5p/COL11A1 axis in colon carcinoma cells, and miR-339-5p repressed colon carcinoma progression via COL11A1 downregulation. These results offer new underlying targets for the accurate therapy of colon carcinoma patients.

Abstract
MicroRNAs have emerged as important regulators of the metastatic process. In addition, circulating miRNAs appear to be surprisingly stable in peripheral blood making them ideal noninvasive biomarkers for disease diagnosis. Here, we performed a proof-of-principle study to investigate the expression profile of circulating miRNAs and their association with the metastatic lymph node status in early breast cancer patients. Sentinel lymph node status was detected by one-step nucleic acid (OSNA) analysis. We performed RNA-sequencing in 16 plasma samples and validated the results by qPCR. Gene Ontology term enrichment and KEGG pathway analyses were carried out using DAVID tools. We found16 differentially expressed miRNAs (q < 0.01) in patients with positive SLNs. Fourteen miRNAs were down-regulated (miR-339-5p, miR-133a-3p, miR-326, miR-331-3p, miR-369-3p, miR-328-3p, miR-26a-3p, miR-139-3p, miR-493-3p, miR-664a-5p, miR-146a-5p, miR-323b-3p, miR-1307-3p and miR-423-3p) and 2 were up-regulated (miR-101-3pand miR-144-3p). Hierarchical clustering using differentially expressed miRNAs clearly distinguished patients according to their lymph node status. Gene ontology analysis showed a significant enrichment of biological processes associated with the regulation of the epithelial mesenchymal transition, cell proliferation and transcriptional regulation. Our results suggest the potential role of several circulating miRNAs as surrogate markers of lymph node metastases in early breast cancer patients. Further validation in a larger cohort of patients will be necessary to confirm our results.

Abstract
Lung cancer remains the leading cause of cancer related mortality worldwide. We aimed to test whether a simple blood biomarker (extracellular vesicle miRNAs) can discriminate between cases with and without lung cancer. METHODS plasma extracellular vesicles (EVs) were isolated from four cohorts (n = 20 in each): healthy non-smokers, healthy smokers, lung cancer, and stable COPD participants. EV miRNA expression was evaluated using the miRCURY LNA miRNA Serum/Plasma assay for 179 specific targets. Significantly dysregulated miRNAs were assessed for discriminatory power using ROC curve analysis. RESULTS 15 miRNAs were differentially expressed between lung cancer and healthy non-smoking participants, with the greatest single miRNA being miR-205-5p (AUC 0.850), improving to AUC 0.993 in combination with miR-199a-5p. Moreover, 26 miRNAs were significantly dysregulated between lung cancer and healthy smoking participants, with the greatest single miRNA being miR-497-5p (AUC 0.873), improving to AUC 0.953 in combination with miR-22-5p; 14 miRNAs were significantly dysregulated between lung cancer and stable COPD participants, with the greatest single miRNA being miR-27a-3p (AUC 0.803), with two other miRNAs (miR-106b-3p and miR-361-5p) further improving discriminatory power (AUC 0.870). CONCLUSION this case control study suggests miRNAs in EVs from plasma holds key biological information specific for lung cancer and warrants further prospective assessment.

Abstract
MicroRNAs (miRNAs/miRs) have important roles in tumor progression in various human cancers. Ultrasound-targeted microbubble destruction (UTMD)-mediated gene transfection has been considered a useful tool for improving cancer treatment. The present study aimed to investigate the role of miR-767 in non-small cell lung cancer (NSCLC) and further analyze the effects of UTMD-mediated miR-767 inhibition on tumor progression. The expression of miR-767 was measured by reverse transcription-quantitative PCR. UTMD-mediated miR-767 inhibition was achieved by the co-transfection of microbubbles and miR-767 inhibitor in NSCLC cells. Cell proliferation was assessed by a CCK-8 assay and cell migration and invasion were examined by a Transwell assay. The expression of miR-767 was increased in NSCLC serum, tissues and cells compared with controls. The reduction of miR-767 in NSCLC cells led to the inhibition of cell proliferation, migration and invasion. UTMD increased the transfection efficiency of the miR-767 inhibitor in NSCLC cells, and UTMD-mediated miR-767 inhibition resulted in a more significant suppressive effect on tumor cell proliferation, migration and invasion. Taken together, the results indicated that miR-767 expression is upregulated in both NSCLC clinical samples and cells. The downregulation of miR-767 can inhibit tumor cell proliferation, migration and invasion, and these effects are further promoted by UTMD-mediated miR-767 inhibition, which indicated the potential of a UTMD-mediated miR-767 inhibition as a novel therapeutic strategy for NSCLC treatment.

Abstract
Recent studies have demonstrated that various long non-coding RNAs (lncRNAs) participate in the gastric cancer (GC) development and metastasis. Some lncRNAs exert their regulatory function by interacting with microRNAs. Here we identified a novel lncRNA RP11-81H3.2 that was highly expressed in the GC tissue and cell lines. RP11-81H3.2 knockdown significantly inhibited the proliferation, migration, and invasion of GC cells. Mechanistically, we demonstrated that RP11-81H3.2 directly interacted with miR-339 while miR-339 regulated the HNRNPA1 expression by targeting HRRNPA1 3'-UTR. RP11-81H3.2-miR-339-HNRNPA1 interaction network regulated the GC cell proliferation, migration, and invasion. Moreover, our results confirmed that RP11-81H3.2 knockdown suppressed the tumor growth of GC in a xenograft model in vivo. In summary, the results suggest that RP11-81H3.2 functions as an oncogene in GC and could be utilized as a promising diagnosis and therapeutic marker for GC treatment.

Abstract
Sepsis is a life-threatening disease caused by infection. Inflammation is a key pathogenic process in sepsis. Paeonol, an active ingredient in moutan cortex (a Chinese herb), has many pharmacological activities, such as anti-inflammatory and antitumour actions. Previous studies have indicated that paeonol inhibits the expression of HMGB1 and the transcriptional activity of NF-κB. However, its underlying mechanism is still unknown. In this study, microarray assay and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) results confirmed that paeonol could significantly up-regulate the expression of miR-339-5p in RAW264.7 cells stimulated by LPS. Dual-luciferase assays indicated that miR-339-5p interacted with the 3′ untranslated region (3′-UTR) of HMGB1. Western blot, immunofluorescence and enzyme-linked immunosorbent assay (ELISA) analyses indicated that miR-339-5p mimic and siHMGB1 both negatively regulated the expression and secretion of inflammatory cytokines (e.g., HMGB1, IL-1β and TNF-α) in LPS-induced RAW264.7 cells. Studies have confirmed that IKK-β is targeted by miR-339-5p, and we further found that paeonol could inhibit IKK-β expression. Positive mutual feedback between HMGB1 and IKK-β was observed when we silenced HMGB1 or IKK-β. These results indicated that paeonol could attenuate the inflammation mediated by HMGB1 and IKK-β by upregulating miR-339-5p expression. In addition, we constructed CLP model mice by cecal ligation and puncture. Paeonol was used to intervene to investigate its anti-inflammatory effect in vivo. The results showed that paeonol could improve the survival rate of sepsis mice and protect the kidney of sepsis mice.

Abstract
BACKGROUND This study aimed to investigate the role of miRNA-339-5p in pancreatic cancer cell invasion and migration. MATERIAL AND METHODS The differences between exosomal miRNAs of PANC02 and PANC02-H7 were studied by microarray analysis. We measured miRNA-339-5p expression in different groups; differences in cell invasion and migration were evaluated using the Transwell and wound healing assays and expression of relative proteins (E-cadherin, vimentin and ZNF689) was measured by WB assay. The correlation between miRNA-339-5p and ZNF689 expression was evaluated by luciferase reporter gene assay. RESULTS Compared with PANC02 exosome, microarray analysis indicated that miRNA-339-5p mRNA expression was significantly suppressed (P<0.001) in the PANC02-H7 exosome. Supplementation with miR-339-5p mimics led to a significant decrease in the invasion cell number and wound healing rate (P<0.001), with significantly enhanced E-cadherin expression and suppressed vimentin expression (P<0.001). However, transfection of a miR-339-5p inhibitor led to a significant increase in the invasion cell number and wound healing rate (P<0.001), with significantly suppressed E-cadherin expression and increased vimentin expression (P<0.001). Luciferase reporter gene assay demonstrated ZNF689 gene to be the target of miR-339-5p in the PANC02-H7 cell. With miR-339-5p and ZNF689 transfection, the invasion cell number and wound healing rate were significantly increased compared with those in the miR-339-5p group (P<0.001), with significantly increased expression of ZNF689 and vimentin and suppressed E-cadherin expression (P<0.001). CONCLUSIONS miR-339-5p suppresses the invasion and migration of pancreatic cancer cells via direct regulation of ZNF689 in vitro.

Abstract
Tumor metastasis is a hallmark of cancer, with distant metastasis frequently developing in lung cancer, even at initial diagnosis, resulting in poor prognosis and high mortality. However, available biomarkers cannot reliably predict cancer spreading sites. The metastatic cascade involves highly complicated processes including invasion, migration, angiogenesis, and epithelial-to-mesenchymal transition that are tightly controlled by various genetic expression modalities along with interaction between cancer cells and the extracellular matrix. In particular, microRNAs (miRNAs), a group of small non-coding RNAs, can influence the transcriptional and post-transcriptional processes, with dysregulation of miRNA expression contributing to the regulation of cancer metastasis. Nevertheless, although miRNA-targeted therapy is widely studied in vitro and in vivo, this strategy currently affords limited feasibility and a few miRNA-targeted therapies for lung cancer have entered into clinical trials to date. Advances in understanding the molecular mechanism of metastasis will thus provide additional potential targets for lung cancer treatment. This review discusses the current research related to the role of miRNAs in lung cancer invasion and metastasis, with a particular focus on the different metastatic lesions and potential miRNA-targeted treatments for lung cancer with the expectation that further exploration of miRNA-targeted therapy may establish a new spectrum of lung cancer treatments.

Abstract
Background Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide, however, the prognosis for HCC remains unsatisfactory. This study aimed to explore the role of miR-339-5p in HCC. Methods We first used quantitative real-time PCR to examine the level of miR-339-5p in HCC tissues. Then we further adopted Western blotting assay, CCK8, cell invasion assays, apoptosis detection assay, and luciferase assay to analyze how it mediate the development of HCC. Results We found that miR-339 is significantly decreased in primary HCC tissues. Overexpression of miR-339 in HCC cells remarkably suppressed proliferation and invasion and induced apoptosis. However, silencing miR-339 in HCC cells promoted proliferation and invasion, and reduced apoptosis. Moreover, we demonstrated that ZNF689 is a target of miR-339 and there is a negative correlation between miR-339 and ZNF689 expression in the HCC tissues. Overexpression of ZNF689 in miR-339-overexpressing HCC cells partially antagonized the inhibitory effects of miR-339. Conclusion Our study revealed that miR-339 inhibits HCC growth through targeting oncoprotein ZNF689 and restoration of miR-339 might be feasible therapeutic strategy for HCC treatment.
