Abstract
CONTEXT Hemangioma (HA) is a benign vascular neoplasm that can lead to permanent scarring. C-C motif chemokine ligand 2 (CCL2) plays a crucial role in facilitating growth and angiogenesis during HA progression. However, the mechanism regulating CCL2 in HA remains poorly elucidated. OBJECTIVE To elucidate the mechanism regulating CCL2 in HA. METHODS Quantitative real-time polymerase chain reaction (RT-qPCR) was employed to determine the expression levels of CCL2, long noncoding RNA (lncRNA) CTBP1 divergent transcript (CTBP1-AS2), and microRNAs (miRNAs). Proliferation, migration, invasion, and angiogenic abilities of human HA endothelial cells (HemECs) were assessed using cell counting kit-8 (CCK-8), colony formation, flow cytometry, transwell, and tube formation assays. Bioinformatics analysis, RNA pull-down, and luciferase reporter assays were conducted to investigate whether CCL2 targets miR-335-5p. Additionally, rescue experiments were performed in this study. RESULTS CCL2 expression was markedly upregulated in HemECs. CCL2 promoted HA cell proliferation, migration, invasion, and angiogenesis while inhibiting apoptosis. CCL2 was directly targeted by miR-335-5p. Additionally, we found that CTBP1-AS2 could function as a competing endogenous RNA (ceRNA) to sponge miR-335-5p, thereby upregulating CCL2. CONCLUSION Our findings suggest that targeting the CTBP1-AS2/miR-335-5p/CCL2 axis may hold promise as a therapeutic strategy for HA.

Cutaneous findings in patients with acromegaly and its relationship with concomitant endocrinopathies. Clin Endocrinol (Oxf) 2024. [PMID: 38712950 DOI: 10.1111/cen.15071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 04/22/2024] [Accepted: 04/27/2024] [Indexed: 05/08/2024]
Abstract
OBJECTIVES Skin changes in acromegaly are often the first sign of the disease. The aim of this study was to describe the cutaneous findings in patients with acromegaly. In addition, a secondary aim was to investigate the possible association of these findings with remission status and concomitant endocrinopathies. DESIGN, PATIENTS, AND MEASUREMENTS In this prospective multicenter study, 278 patients over the age of 18 years with acromegaly who were followed up in 14 different tertiary healthcare institutions were included. These patients, who were followed up by the Endocrinology Department, were then referred to a dermatologist for dermatological examination. The frequency of skin lesions was investigated by detailed dermatologic examination. Dermatological diagnosis is reached by clinical, dermatological and/or dermoscopic examination, and rarely skin punch biopsy examinations in suspicious cases. The possible association of the skin findings between remitted and nonremitted patients and with concomitant endocrinopathies were evaluated. RESULTS The most common skin findings in patients with acromegaly in our study were skin tags (52.5%), cherry angiomas (47.4%), seborrhoea (37%), varicose veins (33%), acneiform lesions (28.8%), hyperhidrosis (26.9%) and hypertrichosis (18.3%). Hypertrichosis was significantly more prevalent in patients nonremitted (p: .001), while xerosis cutis was significantly more prevalent in patients remitted (p: .001). The frequency of diabetes mellitus and hypothyroidism was significantly higher in patients with varicose veins and seborrhoeic keratosis than those without. Additionally, the coexistence of hypothyroidism, hyperthyroidism and galactorrhea was significantly higher in patients with Cherry angioma than in those without Cherry angioma (p-values: .024, .034 and .027, respectively). The frequency of hypogonadism in those with xerosis cutis was significantly higher than in those without (p: .035). CONCLUSIONS Cutaneous androgenization findings such as skin tag, seborrhoea, acne and acanthosis nigricans are common in patients with acromegaly. Clinicians should be aware that skin findings associated with insulin resistance may develop in these patients. It can be said that the remission state in acromegaly has no curative effect on cutaneous findings. Only patients in remission were less likely to have hypertrichosis. This may allow earlier review of the follow-up and treatment of acromegaly patients presenting with complaints of hypertrichosis. Additionally, it can be said that patients with skin findings such as cherry angioma may be predisposed to a second endocrinopathy, especially hypothyroidism. Including dermatology in a multidisciplinary perspective in acromegaly patient management would be beneficial to detect cutaneous findings earlier.

Abstract
A 43-year-old male was diagnosed with vitiligo and had been treated with topical nitrogen mustard at the age of 13. Following two years of treatment, eruptive cherry angiomas developed and presented as widely distributed red papules throughout his trunk and proximal limbs. Ceasing the use of nitrogen mustard slowed the emergence of lesions. This case highlights the potential adverse effects associated with nitrogen mustard treatment in individuals with susceptibility, as it may lead to the onset of eruptive cherry angiomas.

Abstract
Recent studies have revealed the impact of microRNAs (miRNAs) in the carcinogenic process. miR-424 is a miRNA whose role in this process is being to be identified. Experiments in the ovarian cancer, cervical cancer, hepatocellular carcinoma, neuroblastoma, breast cancer, osteosarcoma, intrahepatic cholangiocarcinoma, prostate cancer, endometrial cancer, non-small cell lung cancer, hemangioma and gastric cancer have reported down-regulation of miR-424. On the other hand, this miRNA has been found to be up-regulated in melanoma, laryngeal and esophageal squamous cell carcinomas, glioma, multiple myeloma and thyroid cancer. Expression of this miRNA is regulated by methylation status of its promoter. Besides, LINC00641, CCAT2, PVT1, LIN00657, LINC00511 and NNT-AS1 are among lncRNAs that act as molecular sponges for miR-424, thus regulating its expression. Moreover, several members of SNHG family of lncRNAs have been found to regulate expression of miR-424. This miRNA is also involved in the regulation of E2F transcription factors. The current review aims at summarization of the role of miR-424 in the process of cancer evolution and its impact on clinical outcome of patients in order to find appropriate markers for malignancies.

Abstract
Cherry angiomas are the most common vascular tumors of the skin. They are particularly prevalent in the general population and become more common with age. Although an association with cancer was suggested at the end of the 19th century, when these tumors were first described, it could not be demonstrated. For many decades, therefore, cherry angiomas were considered to have no clinical relevance other than their association with age. A number of studies in recent years, however, have shown a link between cherry angiomas and exposure to various toxic substances and medications, benign and malignant diseases, and immunosuppression, rekindling interest in these lesions and providing clues for a better understanding of their etiology, pathophysiology, and clinical relevance.

Abstract
After skin malignancy, breast cancer is the most widely recognized cancer detected in women in the United States. Breast cancer (BCa) can happen in all kinds of people, but it's much more common in women. One in four cases of cancer and one in six deaths due to cancer are related to breast cancer. Angiogenesis is an essential factor in the growth of tumors and metastases in various malignancies. An expanded level of angiogenesis is related to diminished endurance in BCa patients. This function assumes a fundamental part inside the human body, from the beginning phases of life to dangerous malignancy. Various factors, referred to as angiogenic factors, work to make a new capillary. Expanding proof demonstrates that angiogenesis is managed by microRNAs (miRNAs), which are small non-coding RNA with 19-25 nucleotides. MiRNA is a post-transcriptional regulator of gene expression that controls many critical biological processes. Endothelial miRNAs, referred to as angiomiRs, are probably concerned with tumor improvement and angiogenesis via regulation of pro-and anti-angiogenic factors. In this article, we reviewed therapeutic functions of miRNAs in BCa angiogenesis, several novel delivery carriers for miRNA-based therapeutics, as well as CRISPR/Cas9 as a targeted therapy in breast cancer.

Abstract
MicroRNAs (miR), as important epigenetic control factors, reportedly regulate wound repair. However, our insufficient knowledge of clinically relevant miRs hinders their potential therapeutic use. For this, we performed paired small and long RNA-sequencing and integrative omics analysis in human tissue samples, including matched skin and acute wounds collected at each healing stage and chronic nonhealing venous ulcers (VUs). On the basis of the findings, we developed a compendium (https://www.xulandenlab.com/humanwounds-mirna-mrna), which will be an open, comprehensive resource to broadly aid wound healing research. With this first clinical, wound-centric resource of miRs and mRNAs, we identified 17 pathologically relevant miRs that exhibited abnormal VU expression and displayed their targets enriched explicitly in the VU gene signature. Intermeshing regulatory networks controlled by these miRs revealed their high cooperativity in contributing to chronic wound pathology characterized by persistent inflammation and proliferative phase initiation failure. Furthermore, we demonstrated that miR-34a, miR-424, and miR-516, upregulated in VU, cooperatively suppressed keratinocyte migration and growth while promoting inflammatory response. By combining miR expression patterns with their specific target gene expression context, we identified miRs highly relevant to VU pathology. Our study opens the possibility of developing innovative wound treatment that targets pathologically relevant cooperating miRs to attain higher therapeutic efficacy and specificity.

Abstract
Inflammation promotes cancer development. To a large extent, this can be attributed to the recruitment of myeloid-derived suppressor cells (MDSCs) to tumors. These cells are known for establishing an immunosuppressive tumor microenvironment by suppressing T cell activities. However, MDSCs also promote metastasis and angiogenesis. Critically, as small non-coding RNAs that regulate gene expression, microRNAs (miRNAs) control MDSC activities. In this review, we discuss how miRNA networks regulate key MDSC signaling pathways, how they shape MDSC development, differentiation and activation, and how this impacts tumor development. By targeting the expression of miRNAs in MDSCs, we can alter their main signaling pathways. In turn, this can compromise their ability to promote multiple hallmarks of cancer. Therefore, this may represent a new powerful strategy for cancer immunotherapy.

The miR-424(322)/503 gene cluster regulates pro- versus anti-inflammatory skin DC subset differentiation by modulating TGF-β signaling. Cell Rep 2021; 35:109049.

Abstract
Transforming growth factor β (TGF-β) family ligands are key regulators of dendritic cell (DC) differentiation and activation. Epidermal Langerhans cells (LCs) require TGF-β family signaling for their differentiation, and canonical TGF-β1 signaling secures a non-activated LC state. LCs reportedly control skin inflammation and are replenished from peripheral blood monocytes, which also give rise to pro-inflammatory monocyte-derived DCs (moDCs). By studying mechanisms in inflammation, we previously screened LCs versus moDCs for differentially expressed microRNAs (miRNAs). This revealed that miR-424/503 is the most strongly inversely regulated (moDCs > LCs). We here demonstrate that miR-424/503 is induced during moDC differentiation and promotes moDC differentiation in human and mouse. Inversely, forced repression of miR-424 during moDC differentiation facilitates TGF-β1-dependent LC differentiation. Mechanistically, miR-424/503 deficiency in monocyte/DC precursors leads to the induction of TGF-β1 response genes critical for LC differentiation. Therefore, the miR-424/503 gene cluster plays a decisive role in anti-inflammatory LC versus pro-inflammatory moDC differentiation from monocytes.

Abstract
Excessive proliferation of vascular endothelial cells can cause hemangioma. Although typically benign, hemangiomas can become life-threatening. The microRNA miR-200c-3p is abnormally expressed in some types of tumors, but its expression, biological role, and mechanism of action in infantile hemangioma remain to be fully elucidated. The expression levels of miR-200c-3p in hemangioma tissue were compared with those in adjacent healthy tissue by using bioinformatics analyses and TargetScan. Western blot, enzyme-linked immunosorbent assay, and Cell Counting Kit 8 analyses were used to determine the biological function and site of action of miR-200c-3p in human dermal microvascular endothelial cells (HDMECs). MiR-200c-3p was one of the top 10 differentially expressed genes between healthy tissue, and hemangiomas tissues, having markedly decreased expression in hemangioma tissue. Reduction of miR-200c-3p expression in HDMECs through the transfection of a miR-200c-3p inhibitor significantly increased HDMEC proliferation. The addition of the Notch signaling pathway inhibitor DAPT to HDMECs transfected with the miR-200c-3p inhibitor eliminated the inhibitor-induced enhancement of proliferation in HDMECs. These findings indicate that miR-200c-3p targets the Notch signaling pathway to promote the proliferation of vascular endothelial cells, suggesting that miR-200c-3p plays an important role in the pathogenesis of hemangioma.

Abstract
BACKGROUND Cherry angiomas are benign vascular proliferations of endothelial cells associated with aging. Currently, no mainstay of treatment for these vascular anomalies exists. OBJECTIVE To review existing evidence-based therapies for the treatment of cherry angiomas. METHODS A literature search in May 2019 was performed with PubMed Database and Cochrane Library using the following terms: "cherry angioma," "senile hemangioma," "senile angioma," "cherry hemangioma," and "Campbell de Morgan spots." RESULTS Ten studies included in this systematic review reported laser therapy and nonlaser therapy as efficacious treatments for cherry angiomas. Among the laser therapies, pulsed dye laser (PDL) was preferred over potassium-titanyl-phosphate (KTP) and electrodessication (ED), based on decreased procedure-related pain. The neodymium-doped yttrium aluminum garnet (Nd:YAG) laser 1064 nm produced less pigmentary complications, whereas KTP and PDL risked pigmentary changes in darker-skinned individuals. Nonlaser therapies included cryotherapy, sclerotherapy, electrosurgery (i.e., ED, electrocoagulation), and radiofrequency ablation. No therapy proved to be superior. CONCLUSION A variety of therapeutic modalities exist for the treatment of cherry angiomas. However, a limited number of high-quality studies explored the efficacy of treatments and compared treatment modalities. Light-based methods such as argon, KTP, Nd:YAG, intense pulsed light, and PDL, along with non-light-based interventions such as cryotherapy, electrosurgery, and sclerotherapy effectively treated cherry angiomas.

Extracellular vesicle-encapsulated microRNA-424 exerts inhibitory function in ovarian cancer by targeting MYB. J Transl Med 2021; 19:4. [PMID: 33407591 PMCID: PMC7786507 DOI: 10.1186/s12967-020-02652-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Accepted: 11/30/2020] [Indexed: 02/06/2023] Open
Abstract
Background Recent studies have suggested a crucial role of mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) in ovarian cancer treatment. We, therefore, set out to explore the mechanism through which MSC-derived EVs delivered microRNA-424 (miR-424) to influence the development of ovarian cancer. Methods Bioinformatics analyses were first performed to screen ovarian cancer-related differentially expressed genes and to predict regulatory miRNAs. Then, dual-luciferase reporter gene assay was carried out to verify the relationship between miR-424 and MYB. Subsequently, the characterized MSCs and isolated EVs were co-cultured with ovarian cancer cells, followed by determination of the expression patterns of miR-424, MYB, vascular endothelial growth factor (VEGF), and VEGF receptor (VEGFR), respectively. In addition, the effects of EVs-delivered miR-424 on the proliferation, migration, invasion and tube formation of ovarian cancer cells were assessed using gain- and loss-of-function approaches. Lastly, tumor xenograft was induced in nude mice to illustrate the influence of EVs-loaded miR-424 on ovarian cancer in vivo. Results Our data exhibited that MYB was highly-expressed and miR-424 was poorly-expressed in ovarian cancer. More importantly, MYB was identified as a target gene of miR-424. Additionally, the transfer of miR-424 by MSC-derived EVs was found to repress the proliferation, migration, and invasion of ovarian cancer cells, with a reduction in the expressions of VEGF and VEGFR. Furthermore, MSC-derived EVs over-expressing miR-424 could inhibit the proliferation, migration, and tube formation of human umbilical vein endothelial cells, and also suppressed tumorigenesis and angiogenesis of ovarian tumors in vivo. Conclusion Collectively, our findings indicate that MSC-derived EVs transfer miR-424 to down-regulate MYB, which ultimately led to the inhibition of the tumorigenesis and angiogenesis of ovarian cancer. Hence, this study offers a potential prognostic marker and a therapeutic target for ovarian cancer.

Abstract
MicroRNAs (miRNAs) are a group of non-coding RNAs that play a crucial role in post-transcriptional gene regulation and act as indispensable mediators in several critical biological processes, including tumorigenesis, tissue homeostasis, and regeneration. MiR-424 and miR-503 are intragenic miRNAs that are clustered on human chromosome Xq26.3. Previous studies have reported that both miRNAs are dysregulated and play crucial but paradoxical roles in tumor initiation and progression, involving different target genes and molecular pathways. Moreover, these two miRNAs are concomitantly expressed in several cancer cells, indicating a coordinating function as a cluster. In this review, the roles and regulatory mechanisms of miR-424, miR-503, and miR-424/503 cluster are summarized in different types of cancers.

Abstract
BACKGROUND Some risk factors for malignant melanoma (MM) are recognized. OBJECTIVE To compare the strength of association between MM and eruptive cherry angiomas (CAs) with that of other well-known associations. METHODS This cross-sectional study included all subjects referred to the Outpatient Dermatology-Oncology and Dermoscopy Units of the Universities of Ferrara and Bologna, Italy, over a 5-month period and submitted to total body skin examination. We recorded: age, sex, cutaneous and non-cutaneous malignancies, presence of CAs, arbitrarily considered as "eruptive" when >10, >40 common melanocytic naevi or >2 clinically atypical naevi. The strength of association between the possible risk factors and MM was calculated by odds ratio in both the whole population and age quartiles. Variables associated with MM were included in multiple logistic regression analysis. RESULTS 1,190 subjects were included; 615 had malignant skin tumours, 462 MM, 85 extracutaneous tumours. Five hundred and eighty-seven subjects had eruptive CAs, 485 subjects >40 melanocytic naevi and 368 more than 2 atypical melanocytic naevi. Eruptive CAs, especially in subjects younger than 70, and >2 atypical melanocytic naevi, mostly in subjects older than 50, were significantly associated with MM. The strength of these 2 associations was similar. The presence of >40 melanocytic naevi was not associated with MM. CONCLUSIONS These findings confirmed an association between MM and eruptive CAs, which was as strong as the one between MM and >2 atypical melanocytic naevi. CAs seem an intriguing model of interaction between heterogeneous variables, like immunocompetence, stimuli inducing endothelial cell proliferation, and oncogenesis, which deserves further investigation.

Abstract
Propranolol could repress infantile hemangioma cell growth and induce apoptosis. miR-125b could inhibit cell proliferation in some tumors. However, whether propranolol exerts its proliferation inhibition and apoptosis-promoting effect by regulating the expression of miR-125b needs to be further investigated. In tumor tissue and endothelial cells isolated from infantile hemangioma patients, we found that the expression levels of miR-125b were significantly decreased. In-vitro analysis revealed that propranolol increased the expression of miR-125b in hemangioma cells in a dose-dependent and time-dependent manner. Interestingly, it was observed that regression of miR-125b expression by its inhibitor could abrogate the effect of propranolol on hemangioma cell growth and apoptosis. In addition, our data further identified TFAP4 as a direct target of miR-125b. Collectively, our data provided evidence that propranolol may repress infantile hemangioma cell growth and promote apoptosis through upregulating the miR-125b expression, which exerted its suppression of tumor development by targeting TFAP4.

Abstract
BACKGROUND: Cherry angiomas (CAs) are very common asymptomatic vascular skin lesions. There are only a few studies on CAs in the literature and those assessing risk factors of CAs are scarce. The aim of our study was to determine risk factors for the development of CAs. MATERIALS AND METHODS: A case–control study was conducted at a tertiary care center in Riyadh, Saudi Arabia. Patients underwent a full-body examination for CAs. Demographics and other data including medical history and medications were extracted from electronic medical records. RESULTS: A total of three hundred patients were enrolled: one hundred cases with at least five CAs and two hundred controls without CAs. Bivariate analysis identified benign prostatic hyperplasia (odds ratio [OR]: = 2.591), malignancy (OR = 2.567), tamsulosin (OR = 3.171), and clopidogrel (OR = 0.321) as statistically significant associations. After multivariate logistic regression analysis, only tamsulosin (OR = 3.475, P = 0.009) and clopidogrel (OR = 0.281, P = 0.028) were found to be independent risk factors for CAs. Malignancies tended to be more associated with CAs, but this did not reach statistical significance (P = 0.07). CONCLUSION: Tamsulosin is a possible risk factor for the development of CAs. Clopidogrel seems to have a protective role preventing the development of CAs.

Abstract
Mud crab Scylla paramamosain is one of the most important economic crabs in China. The molecular regulatory mechanism of ovarian development has received considerable attention in recent years. Some studies found that ERK (extracellular signal-regulated protein kinase) signaling pathway plays an important role in ovarian development and is negatively regulated by microRNAs (miRNAs). However, the study about the regulation of miRNA on the ERK pathway in crustacean's ovary remains unknown. In this study, the target genes of the ERK signaling pathway regulated by selected miRNAs identified from the ovary of mud crab in our previous research were predicted by using bioinformatics tools. The results showed that the ERK2 might be a target gene of miR-9c, miR-263a, and miR-263b; MEK2 may be a target gene of miR-263a; and Rap-1b may be a target gene of miR-9, miR-9c, and miR-263a. Results of in vitro dual-luciferase reporter assay showed that the relative luciferase activities were significantly lower in HEK293T cells co-transfected with the combination of miRNA mimics and pmir-RB-REPORTTM-target gene-3'UTR than those with the combination of mimics NC and pmir-RB-REPORTTM-target gene-3'UTR. In contrast, the relative luciferase activities were significantly higher in HEK293T cells co-transfected with miRNA inhibitor than those with inhibitor NC. To further validate in vitro results, the miRNA reagents were injected into the living female mud crabs, and the expression levels of miRNAs and target genes after the injection were analyzed by quantitative real-time PCR. The in vivo experimental results showed that miRNAs (miR-9c/miR-263a) agomir (enhancers)/antagomir (inhibitors) can enhance/decrease the expression of two miRNAs, respectively, and the expression of target genes in the ovary was declined/increased after injection of agomir/antagomir reagent. In conclusion, miR-9/miR-263 can negatively regulate the expression of the ERK pathway genes (ERK2, MEK2, and Rap-1b) in the ovary of mud crab.

Abstract
Angiogenesis requires the temporal coordination of the proliferation and the migration of endothelial cells. Here, we investigated the regulatory role of microRNAs (miRNAs) in harmonizing angiogenesis processes in a three-dimensional in vitro model. We described a microRNA network which contributes to the observed down- and upregulation of proliferative and migratory genes, respectively. Global analysis of miRNA-target gene interactions identified two sub-network modules, the first organized in upregulated miRNAs connected with downregulated target genes and the second with opposite features. miR-424-5p and miR-29a-3p were selected for the network validation. Gain- and loss-of-function approaches targeting these microRNAs impaired angiogenesis, suggesting that these modules are instrumental to the temporal coordination of endothelial migration and proliferation. Interestingly, miR-29a-3p and its targets belong to a selective biomarker that is able to identify colorectal cancer patients who are responding to anti-angiogenic treatments. Our results provide a view of higher-order interactions in angiogenesis that has potential to provide diagnostic and therapeutic insights.

Abstract
An microRNA (miRNA) signature to predict the clinical outcome of pancreatic adenocarcinoma (PAAD) is still lacking. In the current study, we aimed at identifying and evaluating a prognostic miRNA signature for patients with PAAD. The miRNA expression profile and the clinical information regarding patients with PAAD were recruited from The Cancer Genome Atlas database. Differentially expressed miRNAs were identified between normal and tumor samples. By means of survival analysis, a 4-miRNA signature for predicting patients' with PAAD overall survival (OS) was constructed. Receiver operating characteristic (ROC) analysis was applied to determine the efficiency of survival prediction. Furthermore, the biological function of the predicted miRNAs was evaluated using a bioinformatics approach. Four (hsa-mir-126, hsa-mir-3613, hsa-mir-424, and hsa-mir-4772) out of 17 differentially expressed miRNAs were associated to the OS of patients with PAAD. Moreover, the area under the curve (AUC) of the constructed 4-miRNA signature associated to patients' with PAAD 2-year survival was 0.789. The multivariate Cox's proportional hazards regression model suggested that this 4-miRNA signature was an independent prognostic factor of other clinical parameters in patients with PAAD. Further pathway enrichment analyses revealed that the miRNAs in the 4-miRNA signature might regulate genes that affect focal adhesion, Wnt signaling pathway, and PI3K-Akt signaling pathway. Thus, these findings indicated that the 4-miRNA signature might be an effective independent prognostic biomarker in the prediction of PAAD patients' survival.

Abstract
The aim of the study was to assess the association between eruptive cherry angiomas (CAs) and malignant melanoma (MM). Secondary objectives included investigating (i) this association in different age subgroups, and (ii) the association of eruptive CAs with other variables such as malignant tumours, in general, and immunosuppressive treatments. This cross-sectional study involved all patients referred to the outpatient Dermatology-Oncology Units of the universities of Ferrara and Bologna, Italy, and submitted to total body skin examination. These patients were included in a previously collected series. We recorded age, sex, cutaneous and noncutaneous malignancies, immunosuppressive treatments, and presence of CAs. CAs were arbitrarily considered as 'eruptive' when more than or equal to 10. Variables significantly associated with eruptive CAs were included in the logistic regression analysis, also stratified by age. A total of 1693 patients were included in the present study: 500 patients had malignancies, 460 malignant skin tumours, 263 had MM; 150 patients were immunosuppressed; 804 (47.49%) patients had eruptive CAs. In the whole study population, age, immunosuppressive treatment, MM, other skin and nonskin malignant tumours were significantly associated with eruptive CAs at the multivariate analysis. Multivariate analysis in each age subgroup revealed that the association between MM and eruptive CAs was highly significant in younger patients (≤50 years), significant in the 51-70 year-old subgroup, whereas it lost significance in older patients. These findings suggest an association between MM and eruptive CAs, particularly in the lower and intermediate age groups. Both the nature of this association and its possible impact in clinical practice, especially in MM screening, are yet to be established.

Abstract
Retinoblastoma binding protein 6 (RBBP6) is a cancer-related protein that has been implicated in the regulation of cell cycle and apoptosis. RBBP6 isoform 1 has been demonstrated to interact with two tumour suppressors, p53 and pRB. Isoform 1 been shown to regulate p53 through its ubiquitin ligase activity, thus implicating in cell cycle regulation and apoptosis. Isoforms 1 and 2 are multidomain proteins containing a domain with no name (DWNN) domain, a Zinc Finger, a RING Finger, an Rb-binding domain and a p53-binding domain. The RBBP6 isoform 3 comprises the DWNN domain only. Isoform 4 lacks the Rb-binding domain but its role is less understood. RBBP6 isoform 3 has been reported as a cell cycle regulator with anticancer potential. There have been several studies that have clearly demonstrated that RBBP6 may be an important biomarker for cancer diagnosis and a potential drug target for cancer treatment. This work focused on differential expression of RBBP6 transcripts in different cancers, providing detailed analysis of their potential as diagnostic biomarkers for different cancers. These cancers include breast, liver, cervical and colon carcinomas. The expression of RBBP6 transcripts may further provide better understanding of the role of the RBBP6 in carcinogenesis and cell homeostasis.

MicroRNA-424(322) as a new marker of disease progression in pulmonary arterial hypertension and its role in right ventricular hypertrophy by targeting SMURF1. Cardiovasc Res 2019; 114:53-64. [PMID: 29016730 DOI: 10.1093/cvr/cvx187] [Citation(s) in RCA: 56] [Impact Index Per Article: 11.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2016] [Accepted: 09/11/2017] [Indexed: 01/26/2023] Open
Abstract
Aims MicroRNAs (miRNAs) have been implicated in the pathogenesis of pulmonary hypertension (PH), a multifactorial and progressive condition associated with an increased afterload of the right ventricle leading to heart failure and death. The main aim of this study was to correlate the levels of miR-424(322) with the severity and prognosis of PH and with right ventricle hypertrophy progression. Additionally, we intended to evaluate the mechanisms and signalling pathways whereby miR-424(322) secreted by pulmonary arterial endothelial cells (PAECs) impacts cardiomyocytes. Methods and results Using quantitative real-time PCR, we showed that the levels of circulating miR-424(322) are higher in PH patients when compared with healthy subjects. Moreover, we found that miR-424(322) levels correlated with more severe symptoms and haemodynamics. In the subgroup of Eisenmenger syndrome patients, miR-424(322) displayed independent prognostic value. Furthermore, we demonstrated that miR-424(322) targets SMURF1, through which it sustains bone morphogenetic protein receptor 2 signalling. Moreover, we showed that hypoxia induces the secretion of miR-424(322) by PAECs, which after being taken up by cardiomyocytes leads to down-regulation of SMURF1. In the monocrotaline rat model of PH, we found an association between circulating miR-424(322) levels and the stage of right ventricle hypertrophy, as well as an inverse correlation between miR-424(322) and SMURF1 levels in the hypertrophied right ventricle. Conclusions This study shows that miR-424(322) has diagnostic and prognostic value in PH patients, correlating with markers of disease severity. Additionally, miR-424(322) can target proteins with a direct effect on heart function, suggesting that this miRNA can act as a messenger linking pulmonary vascular disease and right ventricle hypertrophy.

Abstract
This study aimed to verify the differentially expressed miRNAs (microRNAs) in hemangioma, and explore their roles in the pathogenesis of hemangioma in vivo and ex vivo. Real-time polymerase chain reaction (PCR) and western blot were used to measure reported differentially expressed miRNAs and their potential targets. In-silicon analysis and luciferase assay were conducted to find the target of miR-15a and miR-205. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and flowcytometry were performed to examine the effect of dysregulation of miR-15a and miR-205 on the proliferation and apoptosis of endothelial cells. Among all candidate miRNAs, only miR-205 level was significantly downregulated whereas miR-15a was evidently upregulated in the hemangioma group. Accordingly, AKT3 was validated to be the direct target of miR-15a and miR-205. Using real-time PCR, the level of AKT1 was much higher in hemangioma group, whereas level of AKT3 was much lower in the hemangioma group, and in general expression level of ATK was upregulated in the hemangioma group. Furthermore, the ATK1 level of cells transfected with miR-205 mimics and ATK1 siRNA was substantially downregulated, and anti-miR-205 mimic significantly improved the level of AKT1, and meanwhile the level of ATK3 and PTEN were remarkably suppressed after transfection with miR-15a mimics and ATK3 siRNA, whereas notably overexpressed after introduction of anti-miR-15a. And miR-15a, AKT3 siRNA and anti-miR-205 evidently induced viability, and miR-205, AKT1 siRNA, and anti-miR-15a obviously promoted apoptosis of cells. CONCLUSION: miR-15a and miR-205 had different expression in hemangioma, may be novel therapeutic targets in the treatment of hemangioma by targeting AKT3 and AKT1.

Abstract
Objective: MicroRNAs are short, noncoding RNA molecules that negatively regulate the stability and translational efficiency of target mRNAs. They are critical regulators of growth and development. Our aim was to identify microRNAs involved in the growth and regulation of infantile hemangiomas. In addition, we searched for the presence of Piwi-interacting RNAs in hemangioma tissue as another regulator of infantile hemangiomas. Methods: RNA was extracted from hemangioma specimens from 3 clinical, age-based categories: proliferative (N = 16), quiescent (N = 8), and involuting (N = 9). RNAs from human dermal microvascular endothelial cells were used as controls. MicroRNA microarray was performed, and the expression profiles of the hemangiomas and endothelial cells were compared using the t test. 5' End-labeling of RNA of our hemangioma specimens was performed for Piwi-interacting RNA detection. Results: Analysis confirmed statistically significant downregulated (N = 18) and upregulated (N = 15) microRNAs. Piwi-interacting RNA analysis did not detect Piwi-interacting RNA transcripts in the hemangioma specimens. Conclusions: The differential expression of microRNAs found in our hemangioma specimens provides insight into the regulation of hemangioma formation and proliferation, quiescence, and fibrofatty involution. Piwi-interacting RNA transcripts were not detected in the hemangioma specimens. These novel findings will help in establishing new therapeutic and diagnostic initiatives for these tumors.

MiR-15b and miR-322 inhibit SETD3 expression to repress muscle cell differentiation. Cell Death Dis 2019; 10:183.

Abstract
SETD3 is a member of SET-domain containing methyltransferase family, which plays critical roles in various biological events. It has been shown that SETD3 could regulate the transcription of myogenic regulatory genes in C2C12 differentiation and promote myoblast determination. However, how SETD3 is regulated during myoblast differentiation is still unknown. Here, we report that two important microRNAs (miRNAs) could repress SETD3 and negatively contribute to myoblast differentiation. Using microRNA (miRNA) prediction engines, we identify and characterize miR-15b and miR-322 as the primary miRNAs that repress the expression of SETD3 through directly targeting the 3’-untranslated region of SETD3 gene. Functionally, overexpression of miR-15b or miR-322 leads to the repression of endogenous SETD3 expression and the inhibition of myoblast differentiation, whereas inhibition of miR-15b or miR-322 derepresses endogenous SETD3 expression and facilitates myoblast differentiation. In addition, knockdown SETD3 in miR-15b or miR-322 repressed myoblasts is able to rescue the facilitated differentiation phenotype. More interestingly, we revealed that transcription factor E2F1 or FAM3B positively or negatively regulates miR-15b or miR-322 expression, respectively, during muscle cell differentiation, which in turn affects SETD3 expression. Therefore, our results establish two parallel cascade regulatory pathways, in which transcription factors regulate microRNAs fates, thereby controlling SETD3 expression and eventually determining skeletal muscle differentiation.

Abstract
Dental surgeries can result in traumatic wounds that provoke major discomfort and have a high risk of infection. In recent years, density research has taken a keen interest in finding answers to this problem by looking at the latest results made in regenerative medicine and adapting them to the specificities of oral tissue. One of the undertaken directions is the study of angiogenesis as an integrative part of oral tissue regeneration. The stimulation of this process is intended to enhance the local availability of stem cells, oxygen levels, nutrient supply, and evacuation of toxic waste. For a successful stimulation of local angiogenesis, two major cellular components must be considered: the stem cells and the vascular endothelial cells. The exosomes are extracellular vesicles, which mediate the communication between two cell types. In regenerative dentistry, the analysis of exosome miRNA content taps into the extended communication between these cell types with the purpose of improving the regenerative potential of oral tissue. This review analyzes the stem cells available for the dentistry, the molecular cargo of their exosomes, and the possible implications these may have for a future therapeutic induction of angiogenesis in the oral wounds.

Abstract
BACKGROUND Dysregulation of the cell cycle has been implicated in esophageal squamous cell carcinoma (ESCC) progression. This study aimed to evaluate the role of miR-424 in cell cycle regulation and ESCC proliferation. METHODS The role of miR-424 in cell proliferation was evaluated in vitro and in vivo. Transcriptional activation of miR-424 was determined using chromatin immunoprecipitation, and binding of miR-424 to targets was verified using miRNA ribonucleoprotein complex immunoprecipitation. FINDINGS miR-424 was upregulated and correlated with poor survival in ESCC patients. Repression or overexpression of miR-424 respectively decreased or increased ESCC cell proliferation in vitro and in vivo. miR-424 expression is transcriptionally regulated by E2F1 and increased during G1/S transition. Knockdown or overexpression of miR-424 respectively inhibited or promoted both G1/S and G2/M cell cycle transitions in ESCC cells, and these effects were mediated by two newly identified miR-424 targets, PRKCD and WEE1, respectively. Consequently, elevation of PRKCD by miR-424 knockdown led to enhanced stability of the p21Cip1 protein via increased activation of PRKCD and downstream p38 MAPK and JNK signaling to block CDK2 activation and G1/S transition, while elevated WEE1 maintained CDC2 in an inactive state to block G2/M transition. However, circLARP4 could sponge the binding of miR-424 to PRKCD, thus compromising the regulation of G1/S progression by miR-424. INTERPRETATION miR-424 coordinates a previously unknown, multilayered regulation of ESCC cell cycle progression to promote ESCC proliferation, and may be used as a novel prognostic marker and an effective therapeutic target for ESCCs.

Abstract
BACKGROUND/AIMS Cherry angiomas (CAs) are one of the most common vascular manifestations of the skin. By and large, these benign lesions often only represent an aesthetic problem. In the literature, few authors have focused on the pathogenesis of these lesions, and some risk factors have been identified, such as the presence of cutaneous and non-skin neoplasias. In this study, the correlation between the distribution of CAs and breast cancer was investigated. METHODS We carried out a study whereby 50 women with unilateral breast cancer and the presence of CAs on the anterior thoracic wall were evaluated, with a particular focus on the difference in the number of CAs between the two haemithoraces. The data was elaborated using the Wilcoxon signed-rank test in order to evaluate whether there was a statistical significance in the distribution of CAs. RESULTS In 31 patients we found that the number of CAs was greater on the cancerous breast than on the contralateral one (p value <0.0001). This was confirmed both in the group of patients suffering from ductal breast cancer and in the group with early invasive breast tumours. CONCLUSION It is not clear whether CAs develop prior to or following breast cancer, indicating the possibility that this cutaneous manifestation could take on a predictive, prognostic development or represent only an epiphenomenon. Further in-depth studies into the pathogenesis of CAs and the relationship with breast cancer could lead to noteworthy diagnostic-therapeutic advances.

Abstract
The last few decades have verified the vital roles of microRNAs in the development of human diseases and witnessed the increasing interest in the prediction of potential disease-miRNA associations. Owning to the open access of many miRNA-related databases, up until recently, kinds of feasible in silico models have been proposed. In this work, we developed a computational model of Maximal Entropy Random Walk on heterogenous network for MiRNA-disease Association prediction (MERWMDA). MERWMDA integrated known disease-miRNA association, pair-wise functional relation of miRNAs and pair-wise semantic relation of diseases into a heterogenous network comprised of disease and miRNA nodes full of information. As a kind of widely-applied biased walk process with more randomness, MERW was then implemented on the heterogenous network to reveal potential disease-miRNA associations. Cross validation was further performed to evaluate the performance of MERWMDA. As a result, MERWMDA obtained AUCs of 0.8966 and 0.8491 respectively in the aspect of global and local leave-one-out cross validation. What' more, three different case study strategies on four human complex diseases were conducted to comprehensively assess the quality of the model. Specifically, one kind of case study on Esophageal cancer and Prostate cancer were conducted based on HMDD v2.0 database. 94% and 88% out of the top 50 ranked miRNAs were confirmed by recent literature, respectively. To simulate new disease without known related miRNAs, Lung cancer (confirmed ratio 94%) associated miRNAs were removed for case study. Lymphoma (verified ratio 88%) was adopted to assess the prediction robustness of MERWMDA based on HMDD v1.0 database. We anticipated that MERWMDA could offer valuable candidates for in vitro biomedical experiments in future.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression at a post-transcriptional level via either the degradation or translational repression of a target mRNA. They play an irreplaceable role in angiogenesis by regulating the proliferation, differentiation, apoptosis, migration and tube formation of angiogenesis-related cells, which are indispensable for multitudinous physiological and pathological processes, especially for the occurrence and development of vascular diseases. Imbalance between the regulation of miRNAs and angiogenesis may cause many diseases such as cancer, cardiovascular disease, aneurysm, Kawasaki disease, aortic dissection, phlebothrombosis and diabetic microvascular complication. Therefore, it is important to explore the essential role of miRNAs in angiogenesis, which might help to uncover new and effective therapeutic strategies for vascular diseases. This review focuses on the interactions between miRNAs and angiogenesis, and miRNA-based biomarkers in the diagnosis, treatment and prognosis of angiogenesis-related diseases, providing an update on the understanding of the clinical value of miRNAs in targeting angiogenesis.

Abstract
The highly conserved RAS-mitogen activated protein kinase (MAPK) signaling pathway is involved in a wide range of cellular processes including differentiation, proliferation, and survival. Somatic mutations in genes encoding RAS-MAPK components frequently occur in many tumors, making the RAS-MAPK a critical pathway in human cancer. Since the pioneering study reporting that let-7 miRNA acted as tumor suppressor by repressing the RAS oncogene, growing evidence has suggested the importance of miRNAs targeting the RAS-MAPK in oncogenesis. MiRNAs alterations in human cancers may act as a rheostat of the oncogenic RAS signal that is often amplified as cancers progress. However, specific mechanisms leading to miRNAs deregulation and their functional consequences in cancer are far from being fully elucidated. In this review, we provide an experimental-validated map of RAS-MAPK oncomiRs and tumor suppressor miRNAs from transmembrane receptor to downstream ERK proteins. MiRNAs could be further considered as potential genetic biomarkers for diagnosis, prognosis, or therapeutic purpose.

Abstract
An accumulated evidence supports that MicroRNAs (miRNAs) have shown a prominent role in pathological processes and different tumor onset. However, to date, the potential functional roles and molecular mechanisms by how microRNA-424-5p(miR-424-5p) affects cancer cell proliferation are greatly unclear, especially in epithelial ovarian cancer(EOC).In this study, we demonstrated that miR-424-5p was significantly down-regulated in EOC tissues and cell lines. The level of miR-424-5p was negatively correlated with tumor size, TNM stage, pathological grade, lymphatic metastasis of EOC. Restoring miR-424-5p expression in EOC cells dramatically suppressed cell proliferation and caused an accumulation of cells in G1 phase, and thus contributed to better prognosis of EOC patients. Mechanistically, miR-424-5p inhibits CCNE1 expression through targeting CCNE1 3'UTR, and subsequent arrest cell cycle in G1/G0 phase by inhibiting E2F1-pRb pathway. This study revealed functional and mechanistic links between miR-424-5p and CCNE1 in the progression of EOC and provide an important insight into that miR-424-5p may serve as a therapeutic target in EOC.

Abstract
BackgroundPropranolol is the first-choice treatment for severe infantile hemangioma (IH). However, 10- 30% of lesions relapse after propranolol treatment. The mechanisms underlying IH recurrence after propranolol treatment have not been completely elucidated.MethodsThis study combined an examination of hemodynamic changes with research regarding hemangioma stem cells (hscs) with differentially expressed microRNAs (miRNAs) to identify the factors affecting IH recurrence after propranolol treatment. Hemodynamic changes were monitored in 21 recurrent cases using high-frequency color Doppler ultrasound, and hscs were treated with different concentrations of propranolol. The levels of differentially expressed miRNAs and the activity of related pathways were then compared between 18 recurrent and 20 non-recurrent IH cases.ResultsDuring treatment, lesion depth and vessel density decreased, and the lesion resistance index increased. Obvious lesions and vessel signals were observed in recurrent cases compared with non-recurrent cases. Propranolol effectively inhibited hscs proliferation. Twenty-two differentially expressed miRNAs were found in the recurrent group compared with the non-recurrent group.ConclusionRecurrence may be attributed to a combination of events. Serum biomarkers and drug treatments for IH recurrence must be studied further.

Abstract
MicroRNAs (miRNAs) exhibit a crucial role in the regulation of angiogenesis and
tumor progression, of which miR-199a-5p (miR-199a) has been reported to function
as a tumor suppressor in multiple malignancies. However, the precise mechanisms
underlying miR-199a in hemangiomas (HAs) remain elusive. In this study, we found
that miR-199a had low expression level, while proliferating cell nuclear antigen
(PCNA) had high expression level in proliferating-phase HAs compared with the
involuting-phase HAs and normal tissues. Spearman correlation analysis revealed
the negative correlation of miR-199a with PCNA expression in proliferating-phase
HAs. In vitro experiments showed that restoration of miR-199a suppressed cell
proliferation capability and induced cell apoptosis in HA-derived endothelial
cells (HDEC) and CRL-2586 EOMA cells, followed with decreased PCNA expression
and increased cleaved caspase-3 expression, but miR-199a inhibitor reversed
these effects. Furthermore, HIF1A was identified as a target of miR-199a and had
negative correlation with miR-199a expression in proliferating-phase HAs.
Overexpression of HIF1A attenuated the anti-proliferation effect of miR-199a
mimic in HAs cells. Taken together, our findings demonstrate that miR-199a may
inhibit proliferation and induce apoptosis in HAs cells via targeting HIF1A and
provide a potential therapeutic target for HAs.

Abstract
Cutaneous squamous cell carcinoma (cSCC) differs from SCC of other organs in its strong association with chronic sun exposure. However, the specific driver mutations in cSCC remain unknown. Fusion genes in established cSCC cell lines (A431 and DJM-1) were predicted by transcriptome sequence, and validated by Sanger sequence, fluorescence in situ hybridization and G-banding. By transcriptome sequencing, we identified fusion gene EGFR-PPARGC1A in A431, which were expressed in 31 of 102 cSCCs. The lesions harboring the fusion gene tended to be located in sun-exposed areas. In vivo cutaneous implantation of EGFR-PPARGC1A-expressing NIH3T3 induced tumors resembling human cSCC, indicating its potent tumorigenicity. NIH3T3 transfected with EGFR-PPARGC1A as well as A431 showed increased cell proliferation activity. With regard to underlying mechanism, EGFR-PPARGC1A protein causes constitutive tyrosine phosphorylation, and induces the phosphorylation of wild-type full-length epidermal growth factor receptor (EGFR) by dimerization. Conversely, the RNAi-mediated attenuation of EGFR or CRISPR/Cas9-mediated knockdown of the fusion gene in A431 led to a decrease in the cell number, and may have therapeutic value. Our findings advance the knowledge concerning genetic causes of cSCC and the function of EGFR, with potential implications for new diagnostic and therapeutic approaches.

Abstract
Infantile hemangioma is the most common benign tumor in infants. Many studies have confirmed that basic fibroblast growth factor (bFGF) and its key receptor FGFR1 are highly expressed in hemangioma. Moreover, several miRNAs can regulate angiogenesis. In this regard, miR-424 often plays a role as tumor suppressor gene. This study was designed to investigate the mechanism of miR-424 in infantile skin hemangioma. Our results showed low expression of miR-424 in infantile skin hemangioma tissues, and that miR-424 overexpression downregulated FGFR1 expression in hemangioma-derived endothelial cells, while miR-424 inhibition upregulated FGFR1 expression. Luciferase reporter analysis confirmed that FGFR1 was a target gene of miR-424. CCK-8, flow cytometry, transwell migration and tube formation assays demonstrated that miR-424 overexpression inhibited cell proliferation, migration and tube formation, at least in part by blocking the bFGF/FGFR1 pathway. In contrast, miR-424 inhibition significantly enhanced these functions. Furthermore, miR-424 overexpression significantly inhibited ERK1/2 phosphorylation, whereas miR-424 inhibition enhanced ERK1/2 phosphorylation. In conclusion, miR-424 could suppress the bFGF/FGFR1 pathway, thereby inhibit ERK1/2 phosphorylation, and thus inhibit cell proliferation, migration and tube formation capabilities and the development of infantile skin hemangioma.

Abstract
Background The aim of this study was to investigate the developmental mechanisms of infantile hemangioma (IH) from the microRNA level. Material/Methods A total of 63 biological specimens of IH were obtained from the First Affiliated Hospital of Jinzhou Medical University and we assessed related miRNAs. Magnetic bead sorting, endocytosis test, canalization assay, and immunofluorescence detection were performed. The IH-derived cells were transfected with related factors and then we assessed the apoptosis and invasion. Results The contents of MiR-455, miR-206, and miR-29a in the proliferative period group (PP) were lower than in the complete regression period group (CR) (P<0.05), and the content of miR-29a in the regression period group (RP) was lower than in the group CR (P<0.05). The post-sorting proliferation capacity was faster than in human umbilical vein endothelial cells, and IH-derived vascular endothelial cells (VECs) exhibited faster canalization ability. The cells transfected with miR-29a exhibited obvious apoptosis 48 h later, the cells transfected with miR-206 exhibited significantly reduced proliferation capacity as well as apoptosis 48 h later, and the invasion capacity was decreased 24 h after transfection. Conclusions miR-29a, miR-206, and miR-455 are differently expressed in different periods of IH, and may participate in regulating multiple functions during the progression of IH.

Abstract
Cartilage originates from mesenchymal cell condensations that differentiate into chondrocytes of transient growth plate cartilage or permanent cartilage of the articular joint surface and trachea. MicroRNAs fine-tune the activation of entire signaling networks and thereby modulate complex cellular responses, but so far only limited data are available on miRNAs that regulate cartilage development. Here, we characterize a miRNA that promotes the biosynthesis of a key component in the RAF/MEK/ERK pathway in cartilage. Specifically, by transcriptome profiling we identified miR-322 to be upregulated during chondrocyte differentiation. Among the various miR-322 target genes in the RAF/MEK/ERK pathway, only Mek1 was identified as a regulated target in chondrocytes. Surprisingly, an increased concentration of miR-322 stabilizes Mek1 mRNA to raise protein levels and dampen ERK1/2 phosphorylation, while cartilage-specific inactivation of miR322 in mice linked the loss of miR-322 to decreased MEK1 levels and to increased RAF/MEK/ERK pathway activation. Such mice died perinatally due to tracheal growth restriction and respiratory failure. Hence, a single miRNA can stimulate the production of an inhibitory component of a central signaling pathway to impair cartilage development.

Abstract
Human cancers are characterized by a number of hallmarks, including sustained proliferative signaling, evasion of growth suppressors, activated invasion and metastasis, replicative immortality, angiogenesis, resistance to cell death, and evasion of immune destruction. As microRNAs (miRNAs) are deregulated in virtually all human cancers, they show involvement in each of the cancer hallmarks as well. In this chapter, we describe the involvement of miRNAs in cancer from a cancer hallmarks and targeted therapeutics point of view. As no miRNA-based cancer therapeutics are available to date, and the only clinical trial on miRNA-based cancer therapeutics (MRX34) was terminated prematurely due to serious adverse events, we are focusing on protein-coding miRNA targets for which targeted therapeutics in oncology are already approved by the FDA. For each of the cancer hallmarks, we selected major protein-coding players and describe the miRNAs that target them.

Abstract
Infantile hemangioma is the most common vascular tumor affecting infants, which is associated with clonal expansion of endothelial cells. The aim of this study is to determine the role of microRNA (miR)-143 in the growth and survival of hemangioma-derived endothelial cells (HemECs). We examined the expression of miR-143 in patients with proliferating-phase (n=10) and involuting-phase (n=8) hemangiomas. The effects of ectopic expression of miR-143 on the viability, proliferation, cell cycle distribution, and apoptosis of HemECs were explored. We also identified the target gene(s) that was involved in the activity of miR-143. It was found that proliferating hemangiomas had significantly (P<0.05) lower levels of miR-143 than involuting counterparts. Reexpression of miR-143 significantly reduced the viability and proliferation of HemECs, while knockdown of miR-143 led to an increase in the proliferation of HemECs. Moreover, overexpression of miR-143 arrested HemECs at the G0/G1 phase and promoted caspase-3-dependent apoptosis. At the molecular level, miR-143 overexpression significantly promoted the expression of p21 and p53 and reduced the expression of cyclin D1, CDK2, CDK4, and Bcl-2. Silencing of Bcl-2 phenocopied the effect of miR-143 overexpression on the proliferation and apoptosis of HemECs. Furthermore, co-expression of Bcl-2 reversed the growth-suppressive effect of miR-143 on HemECs. Taken together, miR-143 acts as a suppressor in the growth of HemECs, at least partially, through downregulation of Bcl-2. Reexpression of miR-143 may represent a potential therapeutic strategy for the treatment of proliferating hemangiomas.

Jin C, Li M, Ouyang Y, Tan Z, Jiang Y. MiR-424 functions as a tumor suppressor in glioma cells and is down-regulated by DNA methylation. J Neurooncol 2017; 133:247-255. [PMID: 28508328 DOI: 10.1007/s11060-017-2438-4] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2016] [Accepted: 04/15/2017] [Indexed: 12/18/2022]
Abstract
Glioma is one of the most lethal malignancies, and increasing reports revealed that microRNAs (miRNAs), a class of small non-coding RNAs, play a critical role in the development and pathology of human gliomas. MiR-424 has been found to be dysregulated in many different types of human cancers. However, the clinical significance and function of miR-424 in glioma remains unclear. Here, based on RTq-PCR analysis in 148 clinical specimens, we found miR-424 expression was significantly decreased in glioma tumor tissues than in adjacent non-neoplastic brain tissues, and decreased miR-424 expression was associated with glioma KPS (P = 0.009) and high grades (P = 0.029). In vitro cellular function assays further revealed that miR-424 inhibited cell invasion and migration, and promoted cell apoptosis. In addition, based on DNA methylation analysis on clinical specimens and cell lines, we found miR-424 promoter CpG island was frequently methylated and correlated with glioma high grades (P = 0.035) and IDH mutation status (P = 0.042). Moreover, the promoter CpG island was demethylated by 5-aza-2'-deoxycytidine treatment in a time-dependent manner and the expression levels of miR-424 were gradually induced and increased. Taken together, our data suggest that the promoter region CpG island methylation is associated with tumor suppressive miR-424 silencing and the pathology of human gliomas.

Genes Dev 2017; 31:553-566. [PMID: 28404630 PMCID: PMC5393051 DOI: 10.1101/gad.292318.116] [Citation(s) in RCA: 74] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2016] [Accepted: 03/06/2017] [Indexed: 01/08/2023]
Abstract
In this study, Rodriguez-Barrueco et al. analyzed ∼3000 primary tumors and show that miR-424(322)/503 is commonly lost in a subset of aggressive breast cancers; they then describe the genetic aberrations that inactivate its expression. Their data show that miR-424(322)/503 is a tumor suppressor in breast cancer and provide a link between mammary epithelial involution, tumorigenesis, and the phenomenon of chemoresistance. The female mammary gland is a very dynamic organ that undergoes continuous tissue remodeling during adulthood. Although it is well established that the number of menstrual cycles and pregnancy (in this case transiently) increase the risk of breast cancer, the reasons are unclear. Growing clinical and experimental evidence indicates that improper involution plays a role in the development of this malignancy. Recently, we described the miR-424(322)/503 cluster as an important regulator of mammary epithelial involution after pregnancy. Here, through the analysis of ∼3000 primary tumors, we show that miR-424(322)/503 is commonly lost in a subset of aggressive breast cancers and describe the genetic aberrations that inactivate its expression. Furthermore, through the use of a knockout mouse model, we demonstrate for the first time that loss of miR-424(322)/503 promotes breast tumorigenesis in vivo. Remarkably, we found that loss of miR-424(322)/503 promotes chemoresistance due to the up-regulation of two of its targets: BCL-2 and insulin-like growth factor-1 receptor (IGF1R). Importantly, targeted therapies blocking the aberrant activity of these targets restore sensitivity to chemotherapy. Overall, our studies reveal miR-424(322)/503 as a tumor suppressor in breast cancer and provide a link between mammary epithelial involution, tumorigenesis, and the phenomenon of chemoresistance.

Abstract
Skin senescence is induced by various factors including intrinsic aging and extrinsic aging. The current study compared the expression of microRNAs in young facial skin and senescent facial skin, and this study identified skin aging-related microRNAs. According to the results from a microRNA PCR Array, miR-124 was the microRNA that increased the most in senescent skin compared to young skin. Real-time PCR with a greater number of samples indicated that the increase in miR-124 levels in senescent facial skin was statistically significant. In situ hybridization was performed, and results indicated that the signal for miR-124 was evident in keratinocytes of senescent skin but not in those of young skin. The morphology of cultured normal human epidermal keratinocytes (NHEKs) transfected with a miR-124 mimic changed to an enlarged and irregular shape. In addition, the number of NHEKs positive for senescence-associated β-galactosidase (SA-β-gal) increased significantly as a result of the overexpression of the miR-124 mimic. The expression of miR-124 increased in UVB-irradiated NHEKs compared to controls in a dose-dependent manner. Expression of miR-124 in A431, a human cutaneous squamous cell carcinoma (SCC) cell line, decreased significantly compared to that in NHEKs. Forced overexpression of miR-124 as a result of the transfection of a miR-124 mimic in A431 resulted in the significant suppression of the proportion of cancer cells. The current results indicated that miR-124 increases as a result of cell senescence and that it decreases during tumorigenesis. The effect of supplementation of miR-124 in an SCC cell line suggests that senescence induction therapy with microRNA may be a new therapeutic approach for treatment of SCC.

[PMID: 27500472 DOI: 10.1002/mc.22536] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2016] [Revised: 07/24/2016] [Accepted: 08/04/2016] [Indexed: 12/28/2022]
Abstract
MiR-424 has been discovered to be involved in the chemoresistance of lung cancer. However, the underlying mechanism by which miR-424 played role in chemoresistance has been unknown. Here, in our study, to investigate the role of miR-424 in non-small cell lung cancer (NSCLC), we have detected the expression of miR-424-3p and -5p in NSCLC tissues and paired normal control. Moreover, to explore the role of miR-424-3p in NSCLC cells, miR-424-3p and -5p were both re-expressed and knocked down using transient transfection with their respective mimics and inhibitors. Cell viability, migration, and invasion were evaluated using MTT, wound-healing and Transwell assays, respectively. It was found that down-regulation of miR-424-3p was pronouncedly associated with NSCLC progression and overall prognosis; and that both miR-424-3p and -5p were markedly capable of preventing the proliferation, migration, and invasion in NSCLC cells. Additionally, it is miR-424-3p but not miR-424-5p that enhances the chemo-sensitivity of NSCLC cells through targeting YAP1. Mechanistically, YAP1 was identified as down-stream target of miR-424-3p. Together, it was for the first time in our study found that it is loss of miR-424-3p not miR-424-5p that enables chemoresistance through targeting YAP1 in NSCLC, supporting that miR-424-3p could be used as therapeutic target in the curing of NSCLC with chemoresistance. © 2016 Wiley Periodicals, Inc.
