Am J Med Sci 2024:S0002-9629(24)01476-9. [PMID: 39313115 DOI: 10.1016/j.amjms.2024.09.009] [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: 09/07/2023] [Revised: 09/19/2024] [Accepted: 09/20/2024] [Indexed: 09/25/2024]
Abstract
BACKGROUND Triple-negative breast cancer (TNBC) is a specific subtype of breast cancer (BC). Some potential molecular targets have been identified, and miR-105-5p was found to be abnormally expressed in TNBC tissues. OBJECTIVE The objective of this study was to probe the effect of miR-105-5p on TNBC via FOXG1/HDAC2-mediated acetylation. METHODS An animal model of TNBC was established by injecting BC cells into the axillary area of nude mice. The levels of miR-105-5p, FOXG1, HDAC2, Bcl-2, Bax, and Ki67 were detected via RT‒qPCR, Western blotting and immunohistochemistry. Flow cytometry, CCK-8, Transwell and colony formation assays were used to measure apoptosis, proliferation and migration, respectively. Total histone acetylation levels were measured by ELISA. The binding of FOXG1 to HDAC2 was detected by co-immunoprecipitation. The binding relationship between miR-105-5p and FOXG1 was verified using a dual-luciferase reporter gene assay. RESULTS In this study, miR-105-5p and HDAC2 were highly expressed in the MDA-MB-231 and BT-549 BC cell lines, whereas FOXG1 was expressed at low levels. The inhibition of miR-105-5p inhibited the proliferation and migration of MDA-MB-231 and BT-549 cells and promoted their apoptosis. Bioinformatics analysis revealed that miR-105-5p and FOXG1 had a negative targeting regulatory relationship. FOXG1 overexpression had a similar effect on cancer cells as the inhibition of miR-105-5p. Moreover, experiments revealed that FOXG1 and HDAC2 could bind to each other and that HDAC2 overexpression or treatment with the histone acetyltransferase inhibitor Garcinol weakened the effect of FOXG1 overexpression. In addition, FOXG1 knockdown inhibited the effect of the miR-105-5p inhibitor, while Garcinol treatment further enhanced the effect of FOXG1 knockdown, inhibited histone acetylation, promoted the proliferation and migration of cancer cells, and inhibited apoptosis. Moreover, the in vivo results confirmed the in vitro results. CONCLUSION miR-105-5p promotes HDAC2 expression by reducing FOXG1, inhibits histone acetylation, and aggravates the malignant biological behavior of TNBC cells.

Impact of microRNA variants on PI3K/AKT signaling in triple-negative breast cancer: comprehensive review. Med Oncol 2024; 41:222. [PMID: 39120634 DOI: 10.1007/s12032-024-02469-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2024] [Accepted: 07/30/2024] [Indexed: 08/10/2024]
Abstract
Breast cancer (BC) is a significant cause of cancer-related mortality, and triple-negative breast cancer (TNBC) is a particularly aggressive subtype associated with high mortality rates, especially among younger females. TNBC poses a considerable clinical challenge due to its aggressive tumor behavior and limited therapeutic options. Aberrations within the PI3K/AKT pathway are prevalent in TNBC and correlate with increased therapeutic intervention resistance and poor outcomes. MicroRNAs (miRs) have emerged as crucial PI3K/AKT pathway regulators influencing various cellular processes involved in TNBC pathogenesis. The levels of miRs, including miR-193, miR-4649-5p, and miR-449a, undergo notable changes in TNBC tumor tissues, emphasizing their significance in cancer biology. This review explored the intricate interplay between miR variants and PI3K/AKT signaling in TNBC. The review focused on the molecular mechanisms underlying miR-mediated dysregulation of this pathway and highlighted specific miRs and their targets. In addition, we explore the clinical implications of miR dysregulation in TNBC, particularly its correlation with TNBC prognosis and therapeutic resistance. Elucidating the roles of miRs in modulating the PI3K/AKT signaling pathway will enhance our understanding of TNBC biology and unveil potential therapeutic targets. This comprehensive review aims to discuss current knowledge and open promising avenues for future research, ultimately facilitating the development of precise and effective treatments for patients with TNBC.

E2F transcription factor-1 modulates expression of glutamine metabolic genes in mouse embryonic fibroblasts and uterine sarcoma cells. BIOCHIMICA ET BIOPHYSICA ACTA. MOLECULAR CELL RESEARCH 2024; 1871:119721. [PMID: 38580088 DOI: 10.1016/j.bbamcr.2024.119721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 03/12/2024] [Accepted: 03/27/2024] [Indexed: 04/07/2024]
Abstract
Metabolic reprogramming is considered as a hallmark of cancer and is clinically exploited as a novel target for therapy. The E2F transcription factor-1 (E2F1) regulates various cellular processes, including proliferative and metabolic pathways, and acts, depending on the cellular and molecular context, as an oncogene or tumor suppressor. The latter is evident by the observation that E2f1-knockout mice develop spontaneous tumors, including uterine sarcomas. This dual role warrants a detailed investigation of how E2F1 loss impacts metabolic pathways related to cancer progression. Our data indicate that E2F1 binds to the promoter of several glutamine metabolism-related genes. Interestingly, the expression of genes in the glutamine metabolic pathway were increased in mouse embryonic fibroblasts (MEFs) lacking E2F1. In addition, we confirm that E2f1-/- MEFs are more efficient in metabolizing glutamine and producing glutamine-derived precursors for proliferation. Mechanistically, we observe a co-occupancy of E2F1 and MYC on glutamine metabolic promoters, increased MYC binding after E2F1 depletion and that silencing of MYC decreased the expression of glutamine-related genes in E2f1-/- MEFs. Analyses of transcriptomic profiles in 29 different human cancers identified uterine sarcoma that showed a negative correlation between E2F1 and glutamine metabolic genes. CRISPR/Cas9 knockout of E2F1 in the uterine sarcoma cell line SK-UT-1 confirmed elevated glutamine metabolic gene expression, increased proliferation and increased MYC binding to glutamine-related promoters upon E2F1 loss. Together, our data suggest a crucial role of E2F1 in energy metabolism and metabolic adaptation in uterine sarcoma cells.

Abstract
The advent of immune checkpoint inhibitors (ICIs) has represented a breakthrough in the treatment of many cancers, although a high number of patients fail to respond to ICIs, which is partially due to the ability of tumor cells to evade immune system surveillance. Non-coding microRNAs (miRNAs) have been shown to modulate the immune evasion of tumor cells, and there is thus growing interest in elucidating whether these miRNAs could be targetable or proposed as novel biomarkers for prognosis and treatment response to ICIs. We therefore performed an extensive literature analysis to evaluate the clinical utility of miRNAs with a confirmed direct relationship with treatment response to ICIs. As a result of this systematic review, we have stratified the miRNA landscape into (i) miRNAs whose levels directly modulate response to ICIs, (ii) miRNAs whose expression is modulated by ICIs, and (iii) miRNAs that directly elicit toxic effects or participate in immune-related adverse events (irAEs) caused by ICIs.
