Project description:FZD7 Plays a Critical Role in Triple Negative Breast Cancer Proliferation
2025-01-24 | E-GEOD-27447 | ExpressionAtlas
Project description:Breast cancer is genetically and clinically heterogeneous. Triple negative cancer (TNBC) is a subtype of breast cancer usually associated with poor outcome and lack of benefit from target therapy. A pathway analysis in a microarray study was performed using TNBC compared with non-triple negative breast cancer (non-TNBC). Overexpression of several Wnt pathway genes, such as frizzled homolog 7 (FZD7), Low density lipoprotein receptor-related protein 6 (LRP6) and transcription factor 7 (TCF7) has been observed in TNBC. Focus was given to the Wnt pathway receptor, FZD7. To validate its function, inhibition of FZD7 using FZD7shRNA was carried out. Notably decreased cell proliferation, suppressed invasiveness and colony formation in triple negative MDA-MB-231 and BT-20 cells were observed. Mechanism study indicated that these effects occurred through silencing the canonical Wnt signaling pathway, as evidenced by loss of nuclear accumulation of ï?¢-catenin and decreased transcriptional activity of TCF7. In vivo study revealed that FZD7shRNA significantly suppressed the tumor formation in xenotransplation mice due to decrease cell proliferation. Our finding suggests that FZD7 involved canonical Wnt signaling pathway is essential for tumorigenesis of TNBC. Thus, FZD7 may be a biomarker and a potential therapeutic target for triple negative breast cancer. 14 pretreatment non-triple negative breast tumors compare with 5 triple negative breast tumor.

Notably decreased cell proliferation, suppressed invasiveness and colony formation in triple negative MDA-MB-231 and BT-20 cells were observed. Mechanism study indicated that these effects occurred through silencing the canonical Wnt signaling pathway, as evidenced by loss of nuclear accumulation of beta-catenin and decreased transcriptional activity of TCF7. In vivo study revealed that FZD7shRNA significantly suppressed the tumor formation in xenotransplation mice due to decrease cell proliferation. Our finding suggests that FZD7 involved canonical Wnt signaling pathway is essential for tumorigenesis of TNBC.

Project description:Centromere protein U (CENPU), which is a critical component of the centromere complex, is involved in the cell filament. However, limited research has been conducted on the relationship between CENPU expression and tumors. Immunohistochemical assessment of clinical samples and analysis of TCGA data revealed a positive correlation between CENPU expression and the degree of invasiveness in breast cancer cells. CENPU promoted stem-cell-like behavior and tumorigenicity and induced malignancy in breast cancer cells. Mechanistically, CENPU promoted furin activity by inhibiting its lysosomal degradation. Furin, which is a precursor-processing enzyme of nerve growth factor (NGF), promoted the conversion of proNGF to NGF which could promote breast cancer stem cells in triple-negative breast cancers. . A tumorigenesis assay conducted in a mouse model showed that CENPU promoted tumorigenesis, and treatment with a furin inhibitor suppressed this effect. Our findings revealed that CENPU plays a critical role in furin-mediated signaling responsible for tumorigenesis. Therefore, CENPU may be a novel molecular target in triple-negative breast cancer.

Project description:Gene expression of triple negative breast cancer
| PRJNA1081147 | ENA
Project description:The shift on energetic demands of proliferating cells during tumorigenesis requires an intense crosstalk between cell cycle and metabolism. Beyond their role in cell proliferation, cell cycle regulators also modulate intracellular metabolism of normal tissues. Using both genetic and pharmacological approaches, we aimed to determine the metabolic role of CDK4 in TNBC cells. Unexpectedly, deletion of CDK4 only slightly reduces cell proliferation of triple negative breast cancer (TNBC) cell line and allows in vivo tumor formation. Furthermore, pro-apoptotic stimuli fail to induce proper cell death in CDK4-silenced, depleted or long-term CDK4/6 inhibitors-treated TNBC cells, with dampened mitochondrial calcium uptake. In the first mass spectrometry-based experiment linked to this project, we explored the proteome and phosphoproteome of WT vs CDK4 KO in triple negative breast cancer cells (MDA-MB-231).
