Single cell RNA-seq of 4T1-T vasculogenic mimicry-competent mammary tumors

Project description:We have previously described a sub-clones of the 4T1 mammary carcinoma cell line that are proficient for vasculogenic mimciry (VM), namely 4T1-E and 4T1-T. In vitro assays suggest that not all cells within these lines a VM-competent. To explore subsets of cells within tumors derived from these cells that may display VM properties we utilized single cell RNA-Seq of 4T1-T mammary fat-pad tumors.

RNA-seq of acLDL high vs low 4T1-T cells

Project description:To determine whether acLDL uptake was associated with specfifc patterns of gene expression we treated vasculogenic mimicry-competent 4T1-T mammary carcinoma cells with Alexa-488 labelled acetylated low density lipoproteins (acLDL) and sorted the cells based on high or low uptake and subjected them to RNA-Seq

Single cell RNA-seq of 4T1 mammary tumors treated with Axitinib

Project description:To understand the effect of hypoxia on vasculogenic mimicry we treated mammary tumour dervied from parental 4T1 cells with vehicle or Axitinib. Tumors were analyzed by scRNA-seq and the expression of endothelial genes assessed in these data with and wihtout Axitinib treatment.

Gene expression of osteosarcama cell line with vasculogenic mimicry phenotype

Project description:Vasculogenic mimicry has been generally accepted as a new form of tumor vascularization and regarded as an unfavorable prognostic factor in multiple aggressive malignancies. We previously reported the presence of vasculogenic mimicry in osteosarcoma patients. The mechanistic basis for osteosarcoma VM remains unclear. We used microarrays to detail the global programme of gene expression between 143B cells and HOS cells exposed to Matrigel which showed greatly different vasculogenic mimicry formation potential and identified distinct classes of vasculogenic mimicry-realted genes during this process.

Role of EGR1 in vasculogenic mimicry of MDA-MB-231 cells

Project description:Vasculogenic mimicry (VM) is an intriguing phenomenon observed in tumor masses, in which cancer cells organize themselves into capillary-like channels that closely resemble the structure and function of blood vessels. Although VM is believed to contribute to alternative tumor vascularization, the detailed regulatory mechanisms controlling these cellular processes remain poorly understood. Our study aimed to investigate the role of Early Growth Response 1 (EGR1) in regulating VM in aggressive cancer cells, specifically MDA-MB-231 triple-negative breast cancer cells.

Erianin abrogates vasculogenic mimicry through targeting m5C methylase NSUN2

Project description:Purpose: The precise temporal and spatial regulation of N5-methylcytosine (m5C) RNA modification plays essential roles in RNA metabolism. Targeting m5C regulation in cancer cells may be a potential strategy for cancer therapy. Erianin is a natural product isolated from Dendrobium chrysotoxum Lindl. Howbeit, the in‐depth understanding of interaction between erianin and m5C modification remains indistinct. Methods: Natural product library screening was used to explore the effects of natural product monomers on uveal melanoma (UM) cells. Intraocular xenografts model was established to examine the effect of erianin. Immunoprecipitation mass spectrometry (IP-MS) and molecular docking analyses were performed to identify NSUN2 as the target of erianin. m5C-meRIP-seq and m5C-meRIP-qPCR analyses were performed to identify the functional target of NSUN2. Tube formation assay and CD31-PAS double staining were used to detect vasculogenic mimicry (VM) in UM. Results: Herein, we report the discovery of erianin as an effective inhibitor of uveal melanoma. Mechanistically, the targeted inhibition of NSUN2 function by erianin results in a decrease in the m5C modification and expression levels of CHAC1 in UM, thereby curtailing the formation of VM. Conclusions: Collectively, our data suggested that erianin significantly inhibited UM progression in vitro and in vivo. Our study unveils a novel therapeutic strategy for combating UM.
