Abstract
The metastasis is a major reason for the poor prognosis of the patients with prostate cancer (PC). Currently, androgen deprivation therapy (ADT) is the basic method for the treatment of PC regardless of surgery or drug treatments. However, ADT therapy is generally not recommended for patients with advanced/metastatic PC. Herein, we report for the first time a long non-coding RNA (lncRNA)-PCMF1 which promotes the progression of Epithelial-Mesenchymal Transition (EMT) in PC cells. Our data demonstrated that PCMF1 in metastatic PC tissues increased significantly compared to non-metastatic specimens. Mechanism research showed that PCMF1 could competitively bind to hsa-miR-137 instead of the 3' -Untranslated Region (UTR) of Twist Family BHLH Transcription Factor 1 (Twist1) by acting as an endogenous miRNA sponge. Furthermore, we found that silence of PCMF1 effectively blocked the EMT in PC cells by indirectly suppressing Twist1 protein mediated by hsa-miR-137 at post-transcriptional level. In summary, our research shows that PCMF1 promotes the EMT of PC cells by causing the functional inactivation of hsa-miR-137 on Twist1 protein, which is an independent risk factor of PC. PCMF1 knockdown combined with hsa-miR-137 expression is a promising PC-targeted therapy. Furthermore, PCMF1 is also expected to act as a useful marker for predicting malignant changes and assessing the prognosis of PC patients.

[PMID: 35260070 PMCID: PMC8905902 DOI: 10.1186/s11658-022-00326-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 02/22/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Accumulating evidence indicates that miR-5195-3p exerts tumor-suppressive roles in several tumors. However, the clinical significance and biological function of miR-5195-3p in prostate cancer (PCa) have not been reported yet. METHODS The expression levels of miR-5195-3p and Cyclin L1 (CCNL1) were determined using quantitative real-time PCR in clinical specimens and cell lines. The clinical significance of miR-5195-3p in patients with PCa was evaluated using Kaplan-Meier survival analysis and Cox regression models. Cell proliferation and cell cycle distribution were measured by CCK-8 assay and flow cytometry, respectively. The association between miR-5195-3p and CCNL1 was analyzed by luciferase reporter assay. RESULTS MiR-5195-3p expression levels were significantly downregulated in 69 paired PCa tissues compared with matched adjacent normal tissues. The decreased miR-5195-3p expression was associated with Gleason score and TNM stage, as well as worse survival prognosis. The in vitro experiments showed that miR-5195-3p overexpression suppressed the proliferation and cell cycle G1/S transition in PC-3 and DU145 cells. Elevated miR-5195-3p abundance obviously impaired tumor formation in vivo using PC-3 xenografts. Mechanistically, CCNL1 was a direct target of miR-5195-3p in PCa cells, which was inversely correlated with miR-5195-3p in PCa tissues. Importantly, CCNL1 knockdown imitated, while overexpression reversed, the effects of miR-5195-3p overexpression on PCa cell proliferation and cell cycle G1/S transition. CONCLUSIONS Our data suggest that miR-5195-3p functions as a tumor suppressor by targeting CCNL1 in PCa.

[PMID: 33104396 PMCID: PMC7791460 DOI: 10.1177/1073274820964783] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/22/2022] Open
Abstract
Objective: This study aims to determine the diagnosis and prediction value of serum
miR-184 and miR-191 levels in patients with non-small-cell lung cancer
(NSCLC). Methods: One hundred patients with NSCLC were enrolled (NSCLC group) and treated with
gefitinib. In addition, 59 pneumonia cases (pneumonia group) and 51 healthy
cases in the corresponding period (normal group) were included. Serum
miR-184 and miR-191 expressions were detected by real-time quantitative
polymerase chain reaction. Furthermore, the relationships between serum
miR-184 and miR-191 expressions and clinicopathological parameters were
analyzed. The use of serum miR-184 and miR-191 levels in the diagnosis of
NSCLC and the prediction of treatment effectiveness and 3-year overall
survival (OS) were assessed by the receiver operating characteristic curve.
Hazard factors affecting the efficacy of treatment in patients with NSCLC
were determined by logistic regression. Results: The serum levels of miR-184 in the NSCLC group were significantly lower than
those in the pneumonia group and normal group, whereas miR-191 expression
was significantly higher in the NSCLC group. Serum miR-184 and miR-191
levels were closely correlated with smoking history, the tumor node
metastasis (TNM) stage, and the degree of pathological differentiation. The
area under curve (AUC) of serum miR-184 combined with miR-191 in the
diagnosis of patients in the NSCLC group and normal group, NSCLC group and
pneumonia group, and the efficacy of treatment in patients with NSCLC was
0.925, 0.929, and 0.916, respectively. The AUC of serum miR-184 and miR-191
for the 3-year OS in patients with NSCLC was 0.869 and 0.879, respectively.
Smoking history, the degree of pathological differentiation, local
treatment, miR-184, and miR-191 were independent risk factors that affected
treatment efficacy. Conclusion: Serum miR-184 and miR-191 levels can potentially be used as molecular markers
to diagnose and predict the curative effect of treatment in patients with
NSCLC.

Abstract
BACKGROUND Studies of microRNAs (miRNAs) and genes have particular interest for cancer biology and medicine due to the discovery of new therapeutic targets and markers. These studies are extensively influenced by anticancer therapy, as miRNAs interfere with the therapy's efficacy in prostate cancer (PCa). OBJECTIVES In this article, we summarise the available data on the influence of radical prostatectomy (RP) and biochemical recurrence on miRNA expression. MATERIALS AND METHODS Molecular targets of these miRNAs, as well as the reciprocal relations between different miRNAs and their targets, were studied using the DIANA, STRING and TransmiR databases. Special attention was dedicated to the mechanisms of PCa development, miRNA, and associated genes as tumour development mediators. RESULTS AND DISCUSSION Combined analysis of the databases and available literature indicates that expression of four miRNAs that are associated with prostate cancer relapse and alter their expression after RP, combined with genes that closely interact with selected miRNAs, has high potential for the prediction of PCa relapse after RP. PCa tissues and biofluids, both immediately after RP for diagnostics/prognostics and in long-term (relapse) monitoring, may be used as sources of these miRNAs. CONCLUSION An overview of the usefulness of published data and bioinformatics resources looking for diagnostic markers and molecular targets is presented in this article. The selected miRNA and gene panels have good potential as prognostic and PCa relapse markers after RP and likely could also serve as markers for therapeutic efficiency on a broader scale.

Global miRNA/proteomic analyses identify miRNAs at 14q32 and 3p21, which contribute to features of chronic iron-exposed fallopian tube epithelial cells. Sci Rep 2021; 11:6270. [PMID: 33737539 PMCID: PMC7973504 DOI: 10.1038/s41598-021-85342-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 03/01/2021] [Indexed: 02/06/2023] Open
Abstract
Malignant transformation of fallopian tube secretory epithelial cells (FTSECs) is a key contributing event to the development of high-grade serous ovarian carcinoma (HGSOC). Our recent findings implicate oncogenic transformative events in chronic iron-exposed FTSECs, including increased expression of oncogenic mediators, increased telomerase transcripts, and increased growth/migratory potential. Herein, we extend these studies by implementing an integrated transcriptomic and mass spectrometry-based proteomics approach to identify global miRNA and protein alterations, for which we also investigate a subset of these targets to iron-induced functional alterations. Proteomic analysis identified > 4500 proteins, of which 243 targets were differentially expressed. Sixty-five differentially expressed miRNAs were identified, of which 35 were associated with the “top” proteomic molecules (> fourfold change) identified by Ingenuity Pathway Analysis. Twenty of these 35 miRNAs are at the 14q32 locus (encoding a cluster of 54 miRNAs) with potential to be regulated by DNA methylation and histone deacetylation. At 14q32, miR-432-5p and miR-127-3p were ~ 100-fold downregulated whereas miR-138-5p was 16-fold downregulated at 3p21 in chronic iron-exposed FTSECs. Combinatorial treatment with methyltransferase and deacetylation inhibitors reversed expression of these miRNAs, suggesting chronic iron exposure alters miRNA expression via epigenetic alterations. In addition, PAX8, an important target in HGSOC and a potential miRNA target (from IPA) was epigenetically deregulated in iron-exposed FTSECs. However, both PAX8 and ALDH1A2 (another IPA-predicted target) were experimentally identified to be independently regulated by these miRNAs although TERT RNA was partially regulated by miR-138-5p. Interestingly, overexpression of miR-432-5p diminished cell numbers induced by long-term iron exposure in FTSECs. Collectively, our global profiling approaches uncovered patterns of miRNA and proteomic alterations that may be regulated by genome-wide epigenetic alterations and contribute to functional alterations induced by chronic iron exposure in FTSECs. This study may provide a platform to identify future biomarkers for early ovarian cancer detection and new targets for therapy.
