Abstract
Breast cancer is the major cancer that affects women all over the world. The awareness over past several decades has led to intensive screening and detection as well as successful treatments. Still, the breast cancer mortality is unacceptable and needs to be urgently addressed. Among many factors, inflammation has often been associated with tumorigenesis, including breast cancer. More than a third of all breast cancer deaths are marked by deregulated inflammation. The exact mechanisms are still not completely known but among the many putative factors, the epigenetic changes, particularly those mediated by non-coding RNAs are fascinating. microRNAs, long non-coding RNAs as well as circular RNAs seem to impact the inflammation in breast cancer which further highlights their important regulatory role in breast cancer pathogenesis. Understanding inflammation in breast cancer and its regulation by non-coding RNAs is the primary objective of this review article. We attempt to provide the most complete information on the topic in hopes of opening new areas of research and discoveries.

Abstract
Breast cancer is the commonest cause of global cancer-related deaths in women and a public health burden in sub-Saharan Africa (SSA). Although the disease incidence in SSA seems lower, mortality rates are disproportionately high in comparison to high-income countries. The global disease burden is growing, with SSA reporting the majority of cases; however, the dearth of information results in insufficient data which is barely representative of the actual disease burden in this population. Future incidence predictions assign the subregion with a majority of the cases and associated deaths. Breast cancer presents with racial and ethnic variations, and available evidence suggests geographical diversity and persistent risk factors that have barely been explored in SSA. Breast cancer is a complex genetic disease, but the genetic risk factors in the extant African population, which is the most genetically diverse population, is scant and of low quality. This review focuses on the burden, prevalence, detection, treatment, survival, biology, as well as risk factors, and reinforces the need for breast cancer-associated risk factor investigation and population-specific studies in SSA.

The anticarcinogen activity of β-arbutin on MCF-7 cells: Stimulation of apoptosis through estrogen receptor-α signal pathway, inflammation and genotoxicity. Mol Cell Biochem 2020; 476:349-360.

Abstract
Arbutin is one of the active ingredients employed in cosmetics as a skin whitening agent. In the present study, the possible effects of arbutin on breast cancer were determined with human breast adenocarcinoma (MCF-7) cells. α and β-arbutin cytotoxicity levels in MCF-7 cells were determined with the MTT method. At low (1-10 mM) doses, α-arbutin appears to be more toxic than β-arbutin. At higher (5-200 mM) and LD50 doses beta arbutin toxicity appears to be higher than alpha arbutin. Thus, the study was continued with β -arbutin. The effects of low and high doses of β-arbutin was determined on oxidative stress, genotoxicity, inflammation, apoptosis, proliferation, endoplasmic reticulum stress and estrogen receptor-α in MCF-7 cells. The results demonstrated that the β-arbutin doses administered to MCF-7 cells did not affect oxidative and endoplasmic reticulum stress in the experimental groups. However, it was found that administration of LD50 dose β-arbutin induced inflammation in these cells via proinflammatory cytokine levels (TNF-α, IFN-γ and IL-1β). It was observed that LD10 and LD50 doses of β-arbutin increased genotoxicity in MCF-7 cells. The gene expression analysis conducted with RT-PCR device and immunocytochemical analysis revealed that β-arbutin at LD50 dose induced apoptosis in MCF-7 cells via p53 and Caspase 3. Furthermore, it was determined that all β-arbutin doses inhibited estrogen receptor-α in MCF-7 cells. Considering that arbutin increased the activation of apoptotic Caspase 3 through p53, which was stimulated by genotoxic and inflammatory effects at LD50 dose in MCF-7 cells. Determination of this mechanism behind these effects of β-arbutin may contribute to the development of a new perspective in treatment.

Abstract
Golgi phosphoprotein 3 (GOLPH3), a Phosphatidylinositol 4-Phosphate [PI(4)P] effector at the Golgi, is required for Golgi ribbon structure maintenance, vesicle trafficking and Golgi glycosylation. GOLPH3 has been validated as an oncoprotein through combining integrative genomics with clinopathological and functional analyses. It is frequently amplified in several solid tumor types including melanoma, lung cancer, breast cancer, glioma, and colorectal cancer. Overexpression of GOLPH3 correlates with poor prognosis in multiple tumor types including 52% of breast cancers and 41% to 53% of glioblastoma. Roles of GOLPH3 in tumorigenesis may correlate with several cellular activities including: (i) regulating Golgi-to-plasma membrane trafficking and contributing to malignant secretory phenotypes; (ii) controlling the internalization and recycling of key signaling molecules or increasing the glycosylation of cancer relevant glycoproteins; and (iii) influencing the DNA damage response and maintenance of genomic stability. Here we summarize current knowledge on the oncogenic pathways involving GOLPH3 in human cancer, GOLPH3 influence on tumor metabolism and surrounding stroma, and its possible role in tumor metastasis formation.

Abstract
Breast cancer is recognized as the most common type of cancer among women with a high rate of mortality all over the world. Over the past years, growing attention has been regarded to realize more about the mechanisms underlying the disease process. It is revealed that the progression of breast cancer may be strongly linked to chronic inflammation owing to the role of inflammatory factors in genetic instability and subsequent cancer predisposition. Although the association between breast cancer and inflammatory pathways has been well-defined now, only recent evidence pointed towards the inflammation-related microRNAs (miRNAs) as potential biomarkers and therapeutic targets involved in the crosstalk of multiple pathways during breast cancer development. Moreover, the practical interactions between these miRNAs and inflammatory factors are also a little characterized. In this review, we intended to describe the effects of predominant inflammatory pathways such as cytokines, phosphoinositide 3-kinase/protein kinase B, and nuclear factor kappa B in association with tumor promoting and tumor suppressing miRNAs on breast cancer progression. Providing new studies in the field of combining biomarkers for early diagnosis, prognosis, and monitoring breast cancer are very important. Notably, understanding the underlying mechanisms of miRNAs as a possible link between inflammation and tumorigenesis may offer a novel insight for combating this epidemic.

Dietary walnut altered gene expressions related to tumor growth, survival, and metastasis in breast cancer patients: a pilot clinical trial. Nutr Res 2019; 66:82-94.

Abstract
Consumption of walnuts has slowed breast cancer growth and/or reduced the risk of mammary cancer in mice. The benefit against cancer was associated with altered expression of genes for cancer growth and survival. We hypothesized that walnut consumption would alter gene expression in pathologically confirmed breast cancers of women in a direction that would be expected to decrease breast cancer growth and survival, as was seen in mice. The study was a nonplacebo, 2-arm, clinical trial. Women with breast lumps large enough for research and pathology biopsies were recruited and randomized to walnut consuming or control groups. Immediately after biopsy collection, women in the walnut group began to consume 2 oz of walnuts per day until follow-up surgery. Pathological studies confirmed that lumps were breast cancer in all women who remained in the trial. At surgery, about 2 weeks after biopsy, additional specimens were taken from the breast cancers. Changes in gene expression in the surgical specimen compared to baseline were determined in each individual woman in walnut-consuming (n = 5) and control (n = 5) groups. RNA sequencing expression profiling revealed that expression of 456 identified genes was significantly changed in the tumor due to walnut consumption. Ingenuity Pathway Analysis showed activation of pathways that promote apoptosis and cell adhesion, and inhibition of pathways that promote cell proliferation and migration. These results support the hypothesis that, in humans, walnut consumption could suppress growth and survival of breast cancers.

Estrogen receptor-α regulation of microRNA-590 targets FAM171A1-a modifier of breast cancer invasiveness. Oncogenesis 2019; 8:5. [PMID: 30631046 PMCID: PMC6328622 DOI: 10.1038/s41389-018-0113-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2018] [Revised: 11/12/2018] [Accepted: 12/11/2018] [Indexed: 12/27/2022] Open
Abstract
The pathobiology and aggressiveness of the triple negative breast cancer (TNBC) are influenced by genes that are preferentially expressed in TNBC cells. However, the nature of such genes with the role in invasiveness of TNBC cells is not fully understood. Here, we identified FAM171A1, member (A1) of the family with sequence similarity 171, as an overexpressed candidate gene in TNBC cells and tumors as compared to estrogen receptor-alpha (ERα) positive breast cancer. We found that the expression of FAM171A1 correlates well with the loss of ERα as well as its newly identified target miR590-5p in TNBC but not in ERα-positive cells. In addition, we report that ERα regulates FAM171A1 expression through a mechanism which involves ERα stimulation of miR590-5p expression via binding to its promoter, and in-turn, miR590-5p suppression of FAM171A1 expression. Further, we found that the levels of FAM171A1 correlate well with cancer cell aggressiveness as depletion or overexpression of FAM171A1 confers reduced or increased ability of TNBC cells to form mammospheres, respectively in accordance with the previous report of increased mammosphere formation potential of metastatic cells. In brief, results presented here have demonstrated that ERα regulation of FAM171A1 expression via miR590-5p explains the molecular basis of the noticed reduced levels of FAM171A1 in ER-positive breast cancer cells and that FAM171A1 is a preferably TNBC- overexpressed gene. Further, the noted loss of ERα-miR590-5p axis may upregulate the expression of FAM171A1 and consequently, resulting aggressiveness of TNBC cells. These findings suggest that FAM171A1 might represent a potentially novel therapeutic target for TNBC tumors.

Abstract
BACKGROUND AND AIMS Hippo signalling is an evolutionarily conserved pathway that controls organ size by regulating cell proliferation, survival, apoptosis, and stem cell self-renewal. In addition, Hippo signalling is profoundly implicated in intestinal regeneration and cancer. However, its roles in the pathogenesis of Crohn's disease [CD] remain largely unexplored. METHODS Quantitative reverse transcription-polymerase chain reaction [qRT-PCR] was performed to identify the deregulated molecules in Hippo signalling. Expression of the highly upregulated Yes-associated protein 1 [YAP] was subsequently examined by qRT-PCR, western blotting, and immunohistochemistry in the intestinal tissues of CD patients and the colons of 2,4,6-trinitrobenzene sulphonic acid [TNBS]-induced colitis mice. The microRNAs [miRNAs] predicted to target YAP were explored by transfection of miR-590-5p mimics or inhibitors and analyzed by luciferase reporter assay. The roles of the miR-590-5p/YAP axis in CD and colorectal cancer were studied in experimental colitis mice and colorectal cancer cell lines. RESULTS YAP mRNA was significantly upregulated in intestinal epithelial cells in CD patients and TNBS-induced colitis mice. MiR-590-5p suppressed YAP expression by directly targeting the YAP 3'-untranslated region in Caco-2 cells and SW620 cells. Upregulation of miR-590-5p in colon reduced YAP level and its downstream targets in intestinal epithelial cells [IECs]. Treatment of miR-590-5p or YAP inhibitor Verteporfin alleviated experimental colitis. Targeting the miR-590-5p/YAP axis inhibited cell proliferation and invasiveness of colorectal cancer [CRC] cells in vitro. CONCLUSIONS Our results suggest that miR-590-5p inhibits intestinal inflammation in mouse colon and tumourigenesis of colorectal cancer cells by inhibiting YAP. The miR-590-5p/YAP axis may be an important novel mechanism in the pathogenesis of CD and colorectal cancer.

Abstract
BACKGROUND Identification of multi-markers is one of the most challenging issues in personalized medicine era. Nowadays, many different types of omics data are generated from the same subject. Although many methods endeavor to identify candidate markers, for each type of omics data, few or none can facilitate such identification. RESULTS It is well known that microRNAs affect phenotypes only indirectly, through regulating mRNA expression and/or protein translation. Toward addressing this issue, we suggest a hierarchical structured component analysis of microRNA-mRNA integration ("HisCoM-mimi") model that accounts for this biological relationship, to efficiently study and identify such integrated markers. In simulation studies, HisCoM-mimi showed the better performance than the other three methods. Also, in real data analysis, HisCoM-mimi successfully identified more gives more informative miRNA-mRNA integration sets relationships for pancreatic ductal adenocarcinoma (PDAC) diagnosis, compared to the other methods. CONCLUSION As exemplified by an application to pancreatic cancer data, our proposed model effectively identified integrated miRNA/target mRNA pairs as markers for early diagnosis, providing a much broader biological interpretation.

Abstract
Background Breast cancer is one of the leading causes of death in women worldwide. Fast growth is the important character of breast cancer, which makes sure the subsequent metastasize and invasion breast cancer. Golgi related genes GOLPH3 has been reported to regulate many kinds of cancers proliferation. However, its upregulator remains largely unknown. miRNA modulate gene expression by post-transcriptional repression to participate in many signaling pathway of breast cancer cell proliferation. miR-590 has been reported to regulate tumorgenesis and could be regulated by its own target ATF-3. But whether miR-590 can be the modulator of Golgi related genes to regulate the breast cancer proliferation is unclear. Methods We performed the bioinformatics analysis of survival rate and expression differences of patients using the data of The Cancer Genome Atlas (TCGA).Both of MTS and BrdU assays were used for cell proliferation analysis. Cell cycle was detected by flow cytometry .qRT-PCR was used for detecting the cell cycle related gene expression. Student’s t-test or One way anova was used for statistics. Results We found the upregulation of GOLPH3 in breast cancer samples compared with normal breast tissues, which also was related to the poor prognosis. Overexpression of GOLPH3 significantly promoted proliferation both of MDA-MB-231 cells (ER negative) and MCF-7 cells (ER positive). We further found that miRNA-590-3p could directly target the 3′-UTR of GOLPH3 mRNA to repress its expression. Overexpression of miR-590-3p inhibited the proliferation of MDA-MB-231 and MCF-7 cells. The rescue experiments indicated that overexpression of GOLPH3 significantly resorted the proliferation inhibited by miR-590-3p. We also found that ATF-3 repressed miR-590-3p expression to modulate miR-590/GOLPH3 pathway to regulate breast cancer cells proliferation. Conclusions This study not only suggests that the ATF-3/miR-590/GOLPH3 signaling pathway is critically involved in the proliferation of breast cancer cells, but provides a novel therapeutic target and new insight base on epigenetic regulation for future breast cancer diagnosis and clinical treatment.

Abstract
MicroRNAs (miRNAs) have been reported to involve in variety of biological progresses. The present study aimed to explore the functional roles of miR-29b in endothelial cells inflammatory damage, as well as the underlying mechanisms. Lipopolysaccharide (LPS) was used to induce endothelial cell inflammation, and the role of miR-29b in endothelial cells inflammatory damage was detected by testing cell viability, cell apoptosis, and the expression of inflammation factors after the suppression or overexpression of miR-29b. Aiming to make clear of the underlying mechanism of miR-29b regulation in inflammation, we studied the relationship between miR-29b and NF-κB/JNK pathway in HUVEC and Eahy926 cells. The results showed that LPS significantly suppressed cell viability, promoted apoptosis and increased TNF-α, IL-1α and INF-γ secretions. MiR-29b was up-regulated in LPS-treated HUVEC and Eahy926 cells. Moreover, suppression of miR-29b alleviated LPS-induced inflammatory injury by promoting cell viability, decreasing apoptosis and reducing the secretions of TNF-α, IL-1α and INF-γ in both HUVEC and Eahy926 cells. On the contrary, overexpression of miR-29b aggravated cell inflammatory injury in both HUVEC and Eahy926 cells. Furthermore, LPS activated NF-κB and JNK signal pathways. However, suppression of miR-29b reduced LPS-activated NF-κB and JNK pathways in both HUVEC and Eahy926 cells. Taken together, these findings concluded that miR-29b could regulate LPS-induced endothelial cells inflammatory injury through regulation of NF-κB and JNK signaling pathways.

Abstract
The abnormal proliferation and migration of airway smooth muscle (ASM) cells play a critical role in airway remodeling during the development of asthma. MicroRNAs (miRNAs) have emerged as critical regulators of ASM cell proliferation and migration in airway remodeling. In this study, we aimed to investigate the potential role of miR-375 in the regulation of platelet-derived growth factor (PDGF)-induced fetal ASM cell proliferation and migration. Our results showed that miR-375 expression was significantly decreased in fetal ASM cells that were treated with PDGF. Functional data showed that overexpression of miR-375 inhibited the proliferation and migration of fetal ASM cells, whereas inhibition of miR-375 enhanced the proliferation and migration of fetal ASM cells. The results of bioinformatics analysis and a dual-luciferase reporter assay showed that miR-375 binds directly to the 3'-untranslated region of Janus kinase 2 (JAK2). Further data confirmed that miR-375 negatively regulates the expression of JAK2 in fetal ASM cells. Moreover, miR-375 also impeded the PDGF-induced activation of signal transducer and activator of transcription 3 (STAT3) in fetal ASM cells. However, restoration of JAK2 expression partially reversed the inhibitory effect of miR-375 on fetal ASM cell proliferation and migration. Overall, our results demonstrate that miR-375 inhibits fetal ASM cell proliferation and migration by targeting JAK2/STAT3 signaling. Our study provides a potential therapeutic target for the development of novel treatment strategies for pediatric asthma.

Abstract
Natural killer (NK) cells have a critical role in controlling virus infections, and viruses have evolved several mechanisms to escape NK cell functions. In particular, Human herpesvirus 6 (HHV-6) is associated with diseases characterized by immune dysregulation and has been reported to infect NK cells. We recently found that HHV-6 in vitro infection of human thyroid follicular epithelial cells and T-lymphocytes modulates several miRNAs associated with alterations in immune response. Since miRNAs are key regulators of many immune pathways, including NK cell functions, we aimed to study the impact of HHV-6A and -6B in vitro infection on the intracellular mediators correlated to NK cell function. To this purpose, a human NK cell line (NK-92) was infected in vitro with HHV-6A or 6B and analyzed for alterations in the expression of miRNAs and transcription factors. The results showed that both viruses establish lytic replication in NK-92 cells, as shown by the presence of viral DNA, expression of lytic transcripts and antigens, and by the induction of an evident cytopathic effect. Notably, both viruses, although with species-specific differences, induced significant modifications in miRNA expression of miRNAs known for their role in NK cell development, maturation and effector functions (miR-146, miR-155, miR-181, miR-223), and on at least 13 miRNAs with recognized role in inflammation and autoimmunity. Also the expression of transcription factors was significantly modified by HHV-6A/6B infection, with an early increase of ATF3, JUN and FOXA2 by both species, whereas HHV-6A specifically induced a 15-fold decrease of POU2AF1, and HHV-6B an increase of FOXO1 and a decrease of ESR1. Overall, our data show that HHV-6A and -6B infections have a remarkable effect on the expression of miRNAs and transcription factors, which might be important in the induction of NK cell function impairment, virus escape strategies and related pathologies.
