ZNF643/ZFP69B exerts oncogenic properties and associates with cell adhesion and immune processes [ChIP-seq]

ABSTRACT: The global cancer burden remains high; thus, it is crucial to entangle molecular mechanisms driving carcinogenesis to improve current prevention and treatment options. We previously detected the ZNF643/ZFP69B gene upregulated in multiple tumors, and we speculated it may play a role in tumor biology. To test this hypothesis, we employed TCGA-centered databases to correlate ZNF643 status with various clinicopathological parameters. We also performed RNA-seq analysis, in vitro studies assessing cancer cell phenotype, and searched for ZNF643-bound genomic loci. Our data indicated higher levels of ZNF643 in most analyzed tumors compared to normal samples, possibly due to copy number variations. ZNF643 mRNA correlated with diverse molecular and immune subtypes and clinicopathological features (tumor stage, grade, patient survival). RNA-seq analysis revealed that ZNF643 silencing triggers the deregulation of the genes implicated in various cancer-related processes, such as growth, adhesion, and the immune system. Moreover, we observed that ZNF643 positively influences cell proliferation, cell cycle, migration, and invasion in a cell type-dependent manner. Finally, our ChIP-seq analysis indicated that the genes associated with ZNF643 binding are linked to adhesion and immune signaling. In conclusion, our data confirm the oncogenic properties of ZNF643 and pinpoint its impact on cell adhesion and immune processes.

Proteomic analysis of breast cancer based on immune subtypes

Project description:Immunotherapy is applied to breast cancer to resolve the limitations of survival gain in existing treatment modalities. With immunotherapy, a tumor can be classified into immune-inflamed, excluded and desert based on the distribution of immune cells. We assessed the clinicopathological features, each subtype’s prognostic value and differentially expressed proteins between immune subtypes.

Breast Cancer - immune clusters - RNA-seq

Project description:We use expression data from breast cancer tumors to define immune clusters in breast cancer. Immune clusters have gradual levels of immune infiltration. In the intermediate immune infiltration cluster, we found a worse prognosis which is independent of known clinicopathological features. We also found the immune clusters associated with treatment response. Further we use gene expression data and deconvolution algorithms to dissect the immune contexture of the clusters.

Differentially expressed miRNAs between HepG2.2.15 and HepG2 cells

Project description:MiRNAs are important posttranscriptional regulators in various physiological processes and their dysregulations have been found in diseases such as infection, imflammation and cancer. Here we compared the miRNA profilings between HBV-producing HepG2.2.15 and its non-HBV maternal HepG2 cell to find potential miRNAs involving in HBV expression. The result indicated that some of the deregulated miRNAs in HepG2.2.15 have been implicated in viral infection and the processes of the immune regulation. HepG2.2.15 vs. HepG2

0.1 Terahertz irradiation alleviates rheumatoid arthritis and exerts immunomodulatory effects in CIA mice

Project description:This study investigated the systemic effects of 0.1 THz irradiation on the inflammatory status of rheumatoid arthritis (RA) in the collagen-induced arthritis (CIA) mouse model. It was found that THz irradiation apparently alleviated the symptoms of arthritis in CIA mice, reducing the joint swelling, mitigating the tissue damage and relieving the expression of pro-inflammatory factors (TNF-, IL-6, RANKL and MMPs) in the swollen joint of the CIA mice. Moreover, the reduction of serum inflammatory cytokines levels together with the reduced CD4+ T cell count and the recovered percentage of regulatory T cells (Treg) indicated that THz irradiation exerted a systemic immunoregulatory activity in CIA mice. The blood leukocyte mRNA-seq GO analysis also enriched several biological processes including the differentiation and adhesion of leukocytes, lymphocyte differentiation and T cell activation, providing additional supporting evidence for the immunoregulatory effects of THz.

Tensin 2 interactomics reveals interaction with GAPDH and a phosphorylation-mediated regulatory role in glycolysis

Project description:Integrin adaptor proteins, like tensin-2, are crucial for cell adhesion and signalling. However, its functions beyond localizing to focal adhesions remain poorly understood. To identify tensin-2's interaction partners in HEK293 cells, we utilized proximity-dependent biotinylation and strep-tag affinity proteomics. Results linked tensin-2 to known focal adhesion proteins and the dystrophin-glycoprotein complex, while also uncovering novel interaction with the glycolytic enzyme GAPDH. We demonstrated that Y483-phosphorylation of tensin-2 regulates the glycolytic rate in HEK293 and MEF cells, as well as gene expression in HEK293 cells. Of note, Y483-phosphorylation directs tensin-2 to adhesion sites in MEF cells. Our study unveils numerous novel interaction partners for tensin-2, further solidifies its speculated role in cell energy metabolism and identifies Y483-phosphorylation as a crucial regulator for tensin-2 localization. These findings shed fresh insight into the functions of tensin-2, highlighting its potential as a therapeutic target for diseases associated with impaired cell adhesion and metabolism.

Fucosyltransferase 4 promotes cancer metastasis via enhancing EGFR/TGFBR signaling network and is associated with poor prognosis in non-small cell lung cancer

Project description:Purpose: Aberrant glycosylation has been known to regulate cancer cell trafficking via promoting intravascular adhesion during metastasis. Clinicopathological studies have also shown a strong correlation between aberrant glycosylation and invasive/metastatic potentials of human cancers. However, the major glycosylation enzymes that drive lung cancer metastases and the signaling networks involved in the process remain incompletely understood. Methods: Two lung adenocarcinoma cell lines, A549 and CL1-0 cells, with FUT4 overexpression and 81 lung cancer tissues and 19 adjacent lung tissues underwent RNA extraction for RNA-seq analysis. Results: We identified fucosyltransferase 4 (FUT4) as a strong predictor of patient prognosis from this RNA-seq cohort. Conclusions: High levels of FUT4 in tumor tissues significantly correlate with poor prognosis in NSCLC patients.

Acupuncture potentiates anti-PD-1 efficacy by promoting CD5+ dentritic cells and T cell-mediated tumor immunity in breast cancer

Project description:Acupuncture has been considered as an available complement therapy against various malignancy cancer by regulating immunity. However, it is not clear whether acupuncture influences the antitumor immune efficacy of PD-1 inhibitor. This study evaluates the efficacy of acupuncture combined with PD-1 inhibitor on the antitumor immune response against breast cancer and revealed the potential molecular mechanisms based on RNA-Seq transcriptome analysis. The results depicted that acupuncture combined with PD-1 inhibitor significantly hindered tumor development by inducing tumor cell apoptosis and inhibiting tumor growth, angiogenesis and metastasis. RNA-Seq analysis indicated that the different expression genes upon acupuncture intervention mainly enriched in immune response, T cell activation and cytokine interaction etc. items containing immune cell-related CD genes (CD5, CD4 and CD8 etc.). Acupuncture stimulation enhanced CD5 expression that had a positive correlation with overall survival of breast cancer patients. The improved immunity including the enhancement of CD5+ dendritic cell, CD4+ and CD8+ T cell content as well as various cytokine (IL-2, IL-6, TNF-α, IFN-γ) secretion in serum was found upon acupuncture combination with PD-1 inhibitor treatment. Taken together, present work reveals that acupuncture intervention promotes the antitumor immune response of PD-1 inhibitor, providing a prospective therapy for ICI therapy against breast cancer.
