Ethyl Acetate Extract of Antenoron Filiforme Inhibits the Proliferation of Triple Negative Breast Cancer Cell via Suppressing SKP2/P21 Signaling Axis

ABSTRACT: Purpose: Antenoron Filiforme is a traditionally used herb medicine in China. Our findings indicate that the ethyl acetate extract of Antenoron Filiforme (AF-EAE) has the ability to inhibit the proliferation of triple negative breast cancer cells (TNBC). However, little is known about the underlying mechanism of AF-EAE's action on TNBC. Methods: Here, we performed RNA sequencing on MDA-MB-231 treated by AF-EAE with two concentrations for 24 hours. The sequence reads that passed quality filters were analyzed at the transcript isoform level with hisat2 followed by HTSeq. Results: Using an optimised data analysis workflow, RNA-seq data showed 1,392 differentially expressed genes (DEGs) after low concentration drug treatment and 2,847 DEGs in the high concentration drug treatment group, with a fold change of ≥1.5 and p-value <0.05. Expression changes in six genes were confirmed by qRT-PCR, demonstrating the high sensitivity of the RNA-seq method. Based on the KEGG pathway enrichment analysis results, cell growth relevant pathways such as "p53 signaling pathway" and "cell cycle" were greatly enriched. In addition, GSEA analysis indicated that DEGs in AF-EAE treated MDA-MB-231 cells were also well enriched in "cell cycle", "DNA replication" and "G2/M cell cycle". Conclusion: Our study indicated that AF-EAE could inhibit the proliferation of TNBC by inducing cell cycle arrest. Meanwhile, we provide a new potential drug treating breast cancer.

Metabolic and lipidomic characterization of radioresistant MDA-MB-231 human breast cancer cells to investigate potential therapeutic targets

Project description:To provide preliminary insights into metabolic and lipidomic characteristics in radioresistant triple-negative breast cancer (TNBC) cells and suggest potential therapeutic targets, we performed a comprehensive metabolic and lipidomic profiling of radioresistant MDA-MB-231 (MDA-MB-231/RR) TNBC cells and their parental cells using gas chromatography-mass spectrometry and nano electrospray ionization-mass spectrometry, followed by multivariate statistical analysis. Buthionine sulfoximine (BSO) and radiation were co-treated to radioresistant TNBC cells. The level of glutathione (GSH) was significantly increased, and the levels of GSH synthesis-related metabolites, such as cysteine, glycine, and glutamine were also increased in MDA-MB-231/RR cells. In contrast, the level of lactic acid was significantly reduced. In addition, reactive oxygen species (ROS) level was decreased in MDA-MB-231/RR cells. In the lipidomic profiles of MDA-MB-231/RR cells, the levels of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) were significantly increased, whereas those of most of the phosphatidylinositol species were significantly decreased. BSO sensitized MDA-MB-231/RR cells to radiotherapy, which resulted in decreased GSH level and increased ROS level and apoptosis. Radioresistant TNBC cells showed distinct metabolic and lipidomic characteristics compared to their parental cells. We suggested activated GSH, PC, and PE biosynthesis pathways as potential targets for treating radioresistant TNBC cells. Particularly, enhanced radiosensitivity was achieved by inhibition of GSH biosynthesis in MDA-MB-231/RR cells.

Navel Orange Peel Essential Oil Inhibits the Growth and Progression of Triple Negative Breast Cancer

Project description:Triple Negative Breast Cancer (TNBC) is a particular type of breast cancer with the highest mortality rate and there has been growing concern about the development of essential oils as potential anti-cancer drugs.This investigation explored the bioactivity and molecular mechanisms of navel orange peel oil (NOPEO) against TNBC cells. By initiating cell cycle block and apoptosis, NOPEO demonstrated potent growth suppressive properties on the TNBC cell lines MDA-MB-231 and MDA-MB-453. NOPEO was also effective in inhibiting the motility of MDA-MB-231 cells and in down-regulating the levels of MMP-9 and MMP-2 proteins. Additionally, NOPEO's inhibitory effects on MDA-MB-231 gene expression were analysed by RNA sequencing. In total, 1376 genes were found to be upregulated and 1335 genes were downregulated after NOPEO treatment. According to KEGG and GO pathways, the differentially expressed genes were related to MAPK, Jak/stat and FoxQ signalling pathways.

LncRNA Uc003xsl.1 Activates of NF-κB/IL8 Axis to Promotes Triple-negative Breast Cancer Progression via A Decoy Role to NKRF [lnc231]

Project description:To discover the potential drivers of TNBC metastasis, we established an in vivo model by injecting MDA-MB-231cells into the tail veins of mice. Then, the breast tumor cells that successfully grew into metastatic lung tumors were collected and expanded in vitro, followed by re-injected into the tail veins of mice for lung metastasis. After three rounds of selection, a highly metastatic subline, MDA-MB-231-P3, was established, and more frequent micro-metastasis was detected in MDA-MB-231-P3 groups than that of MDA-MB-231 groups when the lungs of mice were stained with hematoxylin and eosin (HE). The lncRNA profiles of MDA-MB-231 or MDA-MB-231-P3 cells were analyzed by lncRNA sequencing. A total of 267 lncRNAs in MDA-MB-231-P3 cells were upregulated more than 2-fold in comparison to the MDA-MB-231 cells.

Paclitaxel resistant MDA-MB-231 Cells and resensitization with bexarotene treatment

Project description:Acquired drug resistance represents a major challenge in chemo-therapy treatment for various types of cancers. We have found that the retinoid X receptorâselective agonist bexarotene (LGD1069, Targretin) was efficacious in treating chemo-resistant cancer cells. The goal of this microarray study was to understand the mechanism of bexaroteneâs role in overcoming acquired drug resistance using human breast cancer cells MDA-MB-231 as a model system and paclitaxel as model compound. After MDA-MB-231 cells were repeatedly treated with paclitaxel for 8 cycles with each cycle including a 3-day treatment with 30 nM paclitaxel and followed by a 7-day exposure to control medium, MDA cells resistant to paclitaxel were developed and their growth was no longer inhibited by paclitaxel treatment. Those MDA cells with acquired drug resistance, when treated with paclitaxel and bexarotene in combination, could regain their sensitivity and their growth were again inhibited. Therefore, RNA samples from parental MDA-MB-231 cells, paclitaxel-resistant MDA cells treated with vehicle, paclitaxel alone or in combination with bexarotene, were used for perform global gene expression profiling with Affymetrix HG-U133A gene chips. Keywords: Drug Treatment MDA-MB-231 cells were exposed to regimens on a 10-day cycle: a 3-day treatment with 30 nM paclitaxel and followed by a 7-day exposure to control medium. Paclitaxel resistant MDA-MB-231 cells (MDA-PR) were established within 8 cycles of such treatment (80 days). These MDA-PR cells were then treated with vehicle control, paclitaxel along, or the combination of 30 nM paclitaxel ( 3 days on and 7 days off) and 1 ÂµM Targretin (10 days on) in a new 10-day cycle for 3 months. Thus, there are four treatment groups, parent MDA cells, MDA-PR, MDA-PR treated with paclitaxel, MDA-PR treated with paclitaxel and bexarotene, and each group had four biological replicates.

PCMT1 knockdown attenuates malignant properties by globally regulating transcriptome profiles in triple-negative breast cancer cells

Project description:Breast cancer is the most frequently diagnosed cancer in women, and has high mortality and metastasis rate, especially triple-negative breast cancer (TNBC). As an oncogene, Protein-L-Isoaspartate (D-Aspartate) O-Methyltransferase (PCMT1) is a prognostic biomarker in breast cancer and is highly expressed, while the underlying mechanisms remain unknown. In this study, we silenced PCTM1 in TNBC MDA-MB-231 cells by short hairpin RNA (shPCMT1) to investigate its cellular functions using cell proliferation, apoptosis, migration, and invasion experiments. Following this, the transcriptome sequencing (RNA-seq) experiment was performed to identify the molecular targets of PCMT1, including differentially expressed genes (DEGs) and regulated alternative splicing events (RASEs). We found that shPCMT1 inhibited the proliferation, migration, and invasion of MDA-MB-231 cells. We obtained 1084 DEGs and 2287 RASEs between shPCMT1 and negative control (NC) groups through RNA-seq. The DEGs were highly enriched in immune or inflammation response and cell adhesion-associated pathways, pathways associated with PCMT1 cellular function in cell migration. The RASE genes were enriched in cell cycle-associated pathways and were associated with the altered cell proliferation rate. We finally validated the changed expression and splicing levels of DEGs and RASEs. We found that 34 RNA binding protein (RBP) genes were dysregulated by shPCMT1, including NQO1, S100A4, EEF1A2, and RBMS2. The dysregulated RBP genes could partially explain how PCMT1 regulates the global transcriptome profiles. In conclusion, our study identified the molecular targets of PCMT1 in the TNBC cell line, expands our understanding of the regulatory mechanisms of PCMT1 in cancer progression, and provides novel insights into the progression of TNBC. The identified molecular targets are potential therapeutic targets for future TNBC treatment.

Metabolomics Analysis of Triple Negative Breast Cancer (BCa) Cell Lines

Project description:We used untargeted metabolomic profiling to distinguish this form of BCa from estrogen receptor positive (ER+) subtypes (+/- HER2/neu) and determine that may explain why a commonly used chemotherapeutic, paclitaxel, is generally ineffective at eliciting long-term cytotoxic and/or cytostatic responses in cell line models of TNBC. This metabolomics study used broad spectrum 1H NMR to compare Luminal A (BT474, MCF-7) and triple-negative (MDA-MB-231, MDA-MB-468) BCa cell lines, to determine differences in the two subtypes as well as distinguish therapeutic treatment responses for identifying new targets for drug discovery.
