Differential effects of docosahexaenoic acid (DHA) and linoleic acid (LA) on miR-101 and miR-342 tumor suppressor microRNAs in Taxol-treated HER2-positive breast cancer cells. Clin Nutr ESPEN 2024; 63:502-507. [PMID: 39047867 DOI: 10.1016/j.clnesp.2024.07.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 05/14/2024] [Accepted: 07/06/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND & AIMS Docosahexaenoic acid (DHA) and linoleic acid (LA) have been shown to exhibit anti-proliferative effects against breast cancer cells. However, the mechanisms underlying these effects are not yet fully understood. One potential mechanism is through the regulation of microRNAs (miRs), which are known to play a crucial role in breast cancer development and progression. This study aimed to investigate the expression of miR-342 and miR-101 as tumor-suppressor miRs in the human HER-2 positive breast cancer cell line BT-474 after treatment with DHA, LA, alone or in combination with Taxol, a standard chemotherapy agent. METHODS The human breast cancer cell line BT-474 was cultured, and the IC50 for Taxol was determined using the MTT assay. Cells were then cultured and treated for 24 h with 100 μM DHA and 50 μM LA, alone or in combination with the respective IC50 of Taxol. Cells were harvested, and miRNA extraction and cDNA synthesis were performed using standard methods. Expression levels of miRs were analyzed using quantitative real-time PCR (qRT-PCR), and results were normalized against U6 snRNA expression levels. RESULTS The Taxol IC50 for BT-474 cells was 19 nM. According to the data obtained from our study, it was observed that Taxol treatment resulted in the down-regulation of both miR-101 and miR-342 (3.69 (p < 0.0001) and 1.88 fold, (p < 0.0001) respectively). In addition, DHA, LA and DHA + LA caused up-regulation of miR-101 (0.11, 0.05, 0.03 fold (p < 0.0001) respectively) but not miR-342 (decreased by 1.93 (p < 0.0001), 2.89 (p < 0.0001) and 1.19 fold (p = 0.0029) respectively). Notably, treatment with DHA, LA and DHA + LA was able to restore the down-regulated expression of miR-101 (0.25 (p < 0.0001), 0.05 (p = 0.0012) and 0.06 fold (p < 0.0001) respectively) during Taxol treatment. CONCLUSION Our study demonstrates that DHA and LA can effectively compensate for the reduced expression of miR-101 during Taxol treatment. These findings suggest that dietary fatty acids may play a critical role in modulating the anti-cancer effects of chemotherapy agents. Future studies are needed to investigate the functional aspects of dietary fatty acids on breast cancer development and progression.

Aberrantly reduced expression of miR-342-5p contributes to CCND1-associated chronic myeloid leukemia progression and imatinib resistance. Cell Death Dis 2021; 12:908. [PMID: 34611140 PMCID: PMC8492784 DOI: 10.1038/s41419-021-04209-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 09/08/2021] [Accepted: 09/23/2021] [Indexed: 12/16/2022]
Abstract
Chronic myeloid leukemia (CML) is a myeloproliferative disorder associated with the Philadelphia chromosome, and the current standard of care is the use of tyrosine kinase inhibitors (TKI). However, some patients will not achieve a molecular response and may progress to blast crisis, and the underlying mechanisms remain to be clarified. In this study, next-generation sequencing was used to explore endogenous miRNAs in CML patients versus healthy volunteers, and miR-342-5p was identified as the primary target. We found that miR-342-5p was downregulated in CML patients and had a significant inhibitory effect on cell proliferation in CML. Through a luciferase reporter system, miR-342-5p was reported to target the 3'-UTR domain of CCND1 and downregulated its expression. Furthermore, overexpression of miR-342-5p enhanced imatinib-induced DNA double-strand breaks and apoptosis. Finally, by analyzing clinical databases, we further confirmed that miR-342-5p was associated with predicted molecular responses in CML patients. In conclusion, we found that both in vivo and in vitro experiments and database cohorts showed that miR-342-5p plays a key role in CML patients, indicating that miR-342-5p may be a potential target for future CML treatment or prognostic evaluation.

MiR-342 controls Mycobacterium tuberculosis susceptibility by modulating inflammation and cell death. EMBO Rep 2021; 22:e52252.

Abstract
Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (Mtb) that places a heavy strain on public health. Host susceptibility to Mtb is modulated by macrophages, which regulate the balance between cell apoptosis and necrosis. However, the role of molecular switches that modulate apoptosis and necrosis during Mtb infection remains unclear. Here, we show that Mtb-susceptible mice and TB patients have relatively low miR-342-3p expression, while mice with miR-342-3p overexpression are more resistant to Mtb. We demonstrate that the miR-342-3p/SOCS6 axis regulates anti-Mtb immunity by increasing the production of inflammatory cytokines and chemokines. Most importantly, the miR-342-3p/SOCS6 axis participates in the switching between Mtb-induced apoptosis and necrosis through A20-mediated K48-linked ubiquitination and RIPK3 degradation. Our findings reveal several strategies by which the host innate immune system controls intracellular Mtb growth via the miRNA-mRNA network and pave the way for host-directed therapies targeting these pathways.

Docosahexaenoic acid (DHA) inhibits pro-angiogenic effects of breast cancer cells via down-regulating cellular and exosomal expression of angiogenic genes and microRNAs. Life Sci 2020; 258:118094. [PMID: 32673663 DOI: 10.1016/j.lfs.2020.118094] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 07/08/2020] [Accepted: 07/09/2020] [Indexed: 12/18/2022]
Abstract
AIMS Docosahexaenoic acid (DHA) as an omega 3 free fatty acid has been reported to exert anti-angiogenesis effects. However, our current understanding regarding the precise mechanisms of such effects is still limited. Exosomes secreted by cancer cells may act as angiogenesis promoters. The aim of the study was to determine altered expression levels of HIF-1α, TGF-β, VEGFR, Snail1, Snail2 and SOX2 and their regulating microRNAs in MDA-MB-231 and BT-474 cell lines after treatment with DHA in both normoxic and hypoxic conditions. MAIN METHODS Human breast cancer cell lines including MDA-MB-231 and BT-474 were treated for 24 h with 100 uM DHA under normoxic and hypoxic conditions. Exosomes were isolated from untreated and treated cells and characterized by transmission electron microscopy (TEM) and western blotting. RNAs from cells and isolated exosomes were extracted and cDNAs were synthesized. Expression levels of miRNAs and their pro-angiogenic target genes were analyzed using quantitative real-time PCR (qRT-PCR). KEY FINDINGS We showed significant decrease in the expression of pro-angiogenic genes including HIF1-α, TGF-β, SOX2, Snail1, Snail2 and VEGFR in cells and also their secreted exosomes after treatment with DHA in normoxic and hypoxic conditions. Also the expression levels of tumor suppressor miRs including miR-101, miR-199, miR-342 were increased and the expression levels of oncomiRs including mir-382 and miR-21 were decreased after treatment with DHA in cells and exosomes. SIGNIFICANCE DHA can alter the expression of pro-angiogenic genes and microRNA contents in breast cancer cells and their derived-exosomes in favor of the inhibition of angiogenesis. Our data demonstrated new insight into DHA's anti-cancer action to target not only breast cancer cells but also their derived exosomes to suppress tumor angiogenesis.

Abstract
The pancreatic acinar-enriched miR-216a, miR-216b and miR-217 are encoded within the miR217HG. These miRNAs have been purported to play a tumor suppressive role as their expression is reduced in both human and mouse pancreatic ductal adenocarcinoma (PDAC). To examine this possibility, we generated individual, germline knockout (KO) mice of miR-216a, miR-216b or miR-217. Unlike our previous study showing germline deletion of the miR217HG was embryonic lethal, CRISPR-Cas9 deleted portions of the 5' seed region of the miRNAs produced live births. To investigate possible phenotypes during pancreatic acinar ductal metaplasia (ADM), pancreatic acini from wild type and KO mice were plated on collagen and allowed to transdifferentiate over 4 days. Acini from each of the three miRNA KO mice produced greater numbers of ducts compared to controls. Evaluation of the gene expression during in vitro ADM demonstrated an increase in Krt19 and a reduction in acinar genes (Carboxypeptidase A1, Amylase2a) on day 4 of the transdifferentiation. Recovery was delayed for the miR-216a and miR-216b KOs following caerulein-induced acute pancreatitis. Also predominate in the caerulein treated miR-216a and miR-216b KO mice was the presence of pancreatic duct glands (PDGs). To further establish a phenotype, miRNA KO mice were crossed with EL-KRASG12D (EK) mice and followed up to 13 months of age. While all mice developed severe dysplasia and cystic papillary neoplasms, there existed no apparent phenotypic difference in the miRNA KO/EK mice compared to EK mice. Our data does not support a tumor suppressor role for miR-216a, miR-216b or miR-217 in PDAC and emphasizes the need for phenotypic evaluation of miRNAs in complex in vivo models beyond that performed using cell culture.

Abstract
Background microRNA (miR)-342–3p is frequently dysregulated in human cancers. In the present study, we aimed to explore the expression, prognostic significance, and biological relevance of miR-342-3p in nasopharyngeal carcinoma (NPC). Methods We examined miR-342-3p expression in 79 paired NPC specimens and corresponding normal tissues and analyzed its prognostic impact on overall survival of NPC patients. Gain- and loss-of-function experiments were conducted to determine the biological roles of miR-342-3p. Results Compared with matched normal nasopharyngeal tissues, miR-342-3p was significantly downregulated in NPC (P = 0.0038). Low miR-342-3p expression was significantly correlated with reduced overall survival (P = 0.0084). Ectopic expression of miR-342-3p significantly suppressed proliferation, colony formation, and invasion of NPC cells. In contrast, depletion of miR-342-3p facilitated NPC cell proliferation and invasion. In vivo xenograft studies confirmed that overexpression of miR-342-3p restrained the growth of NPC xenograft tumors. Mechanistically, FOXQ1 served as a functional target of miR-342-3p. There was a significantly negative correlation between miR-342-3p and FOXQ1 expression (r = − 0.487, P = 0.004) in NPC specimens. Overexpression of FOXQ1 rescued the inhibitory effects of miR-342-3p on NPC cell growth and invasion. Conclusions miR-342-3p downregulation predicts poor prognosis in NPC patients and shows suppressive activity against NPC growth and invasion through repression of FOXQ1. Restoration of miR-342-3p may represent a potential therapeutic strategy for NPC.

Abstract
MicroRNAs (miRNAs) play important roles in initiation, development, progression and metastasis of tumors. MiR-342 has been reported as a tumor suppressor or an onco-miRNA based on functions or expression changes in various types of cancers. However, the biological roles and underlying molecular mechanisms of miR-342 in tumorigenesis remain largely unknown. Here, we found that miR-342 was expressed significantly less in a murine MS-K tumor cell line that showed riched blood vessels. Over-expression of miR-342 in MS-K cells inhibited cell proliferation, colony formation, reduced frequency of S phase population in vitro and suppressed tumor growth in vivo. Moreover, increasing miR-342 impeded blood vessels formation and accumulation of macrophages (CD11b+ ) in tumors. By bioinformatic analysis and dual-luciferase reporter assays, chemokine CXCL12 was identified as a direct target of miR-342. Restored Cxcl12 expression in MS-K-miR-342 cells could rescue cell proliferation in vitro. In MS-K-miR-342 tumor-infiltrated macrophages, expression of proangiogenic genes (Vegf-A and Thbs1) and M2-subtype macrophage markers (Cd163, Dectin1 and Ym1) was significantly down-regulated compared with controls. Moreover, lower level of Cxcl12 and its receptor Cxcr4 was observed in the macrophages of MS-K-miR-342 tumors, and MS-K-miR-342 derived miR-342, but not endogenous miR-342, might contribute to Cxcl12 suppression in TAM. These results suggest that miR-342 is involved in MS-K tumor growth as a tumor suppressor by targeting chemokine CXCL12.

Abstract
Lung cancer is the leading cause of cancer-related mortality and non-small cell lung carcinoma (NSCLC) is the most common type. MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. Aberrant expression of miRNAs has been demonstrated to be a prominent feature in NSCLC. The aim of this study was to determine the potential clinical value of serum miR-342-3p in NSCLC. We first evaluated the miR-342-3p levels in NSCLC cell lines, culture media of NSCLC cell lines, and serum samples from NSCLC patients as well as in their respective controls. The associations between serum miR-342-3p levels and clinicopathological parameters as well as clinical outcome were then determined. miR-342-3p expression was significantly downregulated in NSCLC cell lines, culture media of NSCLC cell lines, and the serum samples from NSCLC patients compared to their controls. Serum miR-342-3p discriminated NSCLC patients from healthy individuals. Low expression of serum miR-342-3p was significantly associated with advanced TNM stage and positive lymph node metastasis. In addition, NSCLC patients in the low serum miR-342-3p expression group had remarkably shorter overall survival than those in the high serum miR-342-3p expression group. Serum miR-342-3p was shown to be an independent prognosis factor. In conclusion, serum miR-342-3p might be a promising biomarker for NSCLC that can be used to improve diagnosis and prognosis.
