Serum-Exosome-Derived miRNAs Serve as Promising Biomarkers for HCC Diagnosis. Cancers (Basel) 2022; 15:cancers15010205. [PMID: 36612201 PMCID: PMC9818484 DOI: 10.3390/cancers15010205] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 12/23/2022] [Accepted: 12/25/2022] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Serum exosomes are emerging as key liquid biopsy biomarkers for the early diagnosis of cancer. However, the proportion and distribution of small RNA (sRNA) species from serum exosomes of hepatocellular carcinoma (HCC) patients remain unclear. Effective and reliable biomarkers for HCC diagnosis should be explored. METHODS In this study, we aimed to use sRNA sequencing to profile the sRNAs of serum exosomes in HCC and non-tumor donors. The serum exosomes of 124 HCC patients and 46 non-tumor donors were enrolled for detecting the values of the potential biomarkers for the diagnosis of HCC. RESULTS We found that miRNAs accounted for the maximal percentage of all types of sRNAs both in the serum exosomes of HCC patients and non-tumor donors. This indicated that the serum-exosome-derived microRNAs (miRNAs) were the most valuable as potential biomarkers in HCC diagnosis. Then, miRNAs were set as research candidates. In our Chinese cohorts, three serum-exosome-derived miRNAs (miR-122-5p, let-7d-5p, and miR-425-5p) could be promising biomarkers for distinguishing HCC patients from non-tumor donors. In addition, they were preferred for the early diagnosis of HCC. We also presented the base distribution of some novel serum-exosome-derived miRNAs and described the potential values as biomarkers. CONCLUSIONS The results suggested that the serum-exosome-derived miRNAs were the most crucial sRNA species and they highlighted the potential of serum-exosome-derived miRNAs as promising biomarkers for HCC diagnosis.

Exosomes Derived from RM-1 Cells Promote the Recruitment of MDSCs into Tumor Microenvironment by Upregulating CXCR4 via TLR2/NF- κB Pathway. JOURNAL OF ONCOLOGY 2021; 2021:5584406. [PMID: 34659412 PMCID: PMC8519695 DOI: 10.1155/2021/5584406] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Revised: 08/13/2021] [Accepted: 09/21/2021] [Indexed: 01/15/2023]
Abstract
Myeloid-derived suppressor cells (MDSCs) play a critical role in tumor immune escape because of its remarkable immunosuppressive effect. However, the mechanism of MDSCs migrated into tumor microenvironment remains unclear. In this study, we demonstrated the recruitment of MDSCs can be promoted by exosomes derived from prostate cancer cells, which could upregulate chemokine (CXC motif) receptor 4 (CXCR4) via the TLR2/NF-κB signalling pathway. Flow cytometry detected that the percentage of MDSCs in the mice spleen and tumor tissue was significantly increased after injection with exosomes via mouse tail vein. Transwell chemotaxis assay showed the recruitment of MDSCs toward the lower chamber was enhanced after stimulation with exosomes, and the migration ability could be inhibited by AMD3100 (a CXCR4 specific inhibitor) both in vivo and in vitro. Additionally, Western blot and flow cytometry verified a remarkably increase of CXCR4 in MDSCs after incubation with exosomes; meanwhile, the protein level of TLR2 and activation of NF-κB were also strengthened obviously. Nevertheless, after blocking TLR2 by C29 (a TLR2-specific inhibitor), the expression of p-p65 and CXCR4, which were hypothesized as the downstream target of TLR2, was prominently reduced. In conclusion, prostate cancer-derived exosomes could reinforce CXCR4 expression in MDSCs through the TLR2/NF-κB signalling pathway, eventually promoting migration of MDSCs into tumor microenvironment in a CXCR4-CXCL12 axis-dependent manner.

[PMID: 33164833 DOI: 10.1016/j.lfs.2020.118638] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 09/30/2020] [Accepted: 10/19/2020] [Indexed: 12/24/2022]
Abstract
AIM Prostate-specific G-protein coupled receptor (PSGR) in prostate cancer (Pca) are associated with poor overall survival. However, the effect of exosomal PSGR on PCa metastasis remains unknown. MAIN METHODS The effect of exosome derived from PSGR-overexpressed PC3 cells (PC3 PSGR+ exosomes) on migration, invasion, epithelial-mesenchymal transition (EMT) and stemness of low invasive cells (LNCaP and RWPE-1) was assessed. Transcriptome sequencing was performed to identify differentially expressed (DE) mRNAs in low invasive cells incubated by PC3 PSGR+ exosomes or negative control (NC) exosomes. KEY FINDINGS The PSGR was stably overexpressed in PC3 cells. The PC3 PSGR+ exosomes were internalized in LNCaP and RWPE-1cells, and significantly promoted cells migration and invasion. The expression of E-cadherin was decreased, and Vimentin, Snail, SOX2 and OCT4a was increased in low invasive cells after PC3 PSGR+ exosome incubation. Additionally, a total of 993 and 1170 DE mRNAs were respectively identified in LNCaP and RWPE-1 cells after PC3 PSGR+ exosome incubation, and 5 upregulated mRNAs and 11 down regulated mRNAs were shared. The DE mRNAs were predominantly implicated in "activation of Rho GTPase activity" and "response to zinc ion" in LNCaP cells, and "extracellular matrix organization" and "patterning of blood vessels" in RWPE-1 cells. The KEGG analysis showed the DE mRNAs were enriched in pathways associated with EMT such as "Adherens junction", "Cell adhesion molecules (CAMs)" and "Focal adhesion". SIGNIFICANCE Exosomal PSGR promoted migration, invasion, stemness and epithelial-mesenchymal transitions, and reshaped the mRNAs profiling of LNCaP and RWPE-1 cells.

Abstract
Objective: To investigate the effect of long noncoding RNA GM16343 on interleukin 36β promotion of
CD8+T cells in tumor microenvironment regulation. Methods: The differentially expressed long noncoding RNA in interleukin 36β-stimulated mouse
CD8+T cells was screened by gene chip technology, and the significant
differentially expressed long noncoding RNAs were verified by real-time polymerase chain
reaction. The lentiviral vector that overexpresses or knockdown GM16343 was constructed,
transfected into CD8+T cells, and stimulated with interleukin 36β, and the
amount of interferon γ secreted was detected by enzyme-linked immunosorbent assay. A
mouse subcutaneous xenograft model that stably express interleukin 36β was established,
and the tumor size and mouse survival time were observed by stimulation with
CD8+T cells overexpression or knockdown of GM16343. Results: A total of 12 long noncoding RNAs with significant differences were screened by gene
chip analysis. Real-time polymerase chain reaction showed that the difference in GM16343
was larger, and the difference between the groups was observed to be the most
significant. Compared to control group, CD8+T cells overexpressing GM16343
increased the secretion of interferon γ, and the tumor diameter of the mice after
stimulation showed significant reduction, and the survival time showed significant
prolongation. Compared to control group, the CD8+T cells after GM16343 were
knocked down. The interferon γ secretion was decreased, and no significant change in
tumor diameter and survival time was observed. Conclusion: Interleukin 36β may enhance antitumor immune response of CD8+T cells by
regulating GM16343.

Abstract
Colorectal cancer (CRC) is one of the most common types of human cancers. However, the mechanisms underlying CRC progression remained elusive. This study identified differently expressed messenger RNAs (mRNAs), long noncoding RNAs (lncRNAs), and small nucleolar RNAs (snoRNAs) between pre-therapeutic biopsies and post-therapeutic resections of locally advanced CRC by analyzing a public dataset, GSE94104. We identified 427 dysregulated mRNAs, 4 dysregulated lncRNAs, and 19 dysregulated snoRNAs between pre- and post-therapeutic locally advanced CRC samples. By constructing a protein–protein interaction network and co-expressing networks, we identified 10 key mRNAs, 4 key lncRNAs, and 7 key snoRNAs. Bioinformatics analysis showed therapy-related mRNAs were associated with nucleosome assembly, chromatin silencing at recombinant DNA, negative regulation of gene expression, and DNA replication. Therapy-related lncRNAs were associated with cell adhesion, extracellular matrix organization, angiogenesis, and sister chromatid cohesion. In addition, therapy-related snoRNAs were associated with DNA replication, nucleosome assembly, and telomere organization. We thought this study provided useful information for identifying novel biomarkers for CRC.

Abstract
MicroRNA-1303 (miR-1303) is involved in the tumorigenesis and progression of several cancers, and yet the role of miR-1303 in prostate cancer (PCa) and its underlying mechanism are unknown. To explore this issue, the present study aimed to use PCa tissues, cell lines and a PCa-engrafted mouse model to determine the expression and roles of miR-1303 in PCa. Furthermore, a series of experiments were conducted to explore the underlying mechanisms of action of miR-1303 in PCa cells. miR-1303 was demonstrated to be highly expressed in PCa tissues and cell lines. The level of miR-1303 expression was closely associated with higher Gleason scores and a more developed tumor stage in patients with PCa, and patients with higher levels of miR-1303 displayed a reduced overall survival rate. miR-1303 overexpression promoted the proliferation, migration and invasion of PCa cells. In vivo experiments showed that miR-1303 inhibition suppressed the growth of PCa tumors in mice. Additionally, dickkopf Wnt signaling pathway inhibitor 3 (DKK3) was identified as a target of miR-1303. Knockdown of miR-1303 suppressed the proliferation, migration and invasion of PCa cells, increased DKK3 expression, and inhibited the activity of the Wnt/β-catenin pathway. In conclusion, miR-1303 may promote proliferation, migration and invasion of PCa cells through activating the Wnt/β-catenin pathway by regulating DKK3 expression. These results indicated that miR-1303 may be considered as a potential biomarker for PCa treatment.

Abstract
BACKGROUND This meta-analysis was performed to evaluate the relationship between hypoxia-inducible factor-1α (HIF1α) 1790G/A gene polymorphism and the susceptibility to renal cell carcinoma (RCC) and prostate cancer (PCa). METHODS Association investigations were identified and included from the Embase, Cochrane Library and PubMed databases on March 1, 2018, and eligible investigations were analyzed by meta-analysis. Odds ratios (OR) were used to express the dichotomous data, and the 95% confidence intervals (CI) were also calculated. RESULTS In this meta-analysis, we found that the AA genotype of HIF1α 1790G/A was positively associated with the risk of RCC in overall populations, Caucasians, but not for Asians. G allele and GG genotype were not associated with the susceptibility of RCC in overall populations, Caucasians, and Asians. The G allele was negatively associated with PCa susceptibility in overall populations, Asians, but not for Caucasians. GG genotype was negatively associated with PCa susceptibility in Asians, but not for overall populations and Caucasians. HIF1α 1790G/A AA genotype was not associated with PCa susceptibility in overall populations of Caucasians or Asians. CONCLUSION AA genotype of HIF1α 1790G/A was positively associated with RCC risk in overall populations and Caucasians. Furthermore, the G allele was negatively associated with prostate cancer susceptibility in overall populations, Asians, and GG genotype was negatively associated with PCa susceptibility in Asians.
