Recombinant Dual-target MDM2/MDMX Inhibitor Reverses Doxorubicin Resistance through Activation of the TAB1/TAK1/p38 MAPK Pathway in Wild-type p53 Multidrug-resistant Breast Cancer Cells
Chemotherapy resistance represents a major obstacle for the treatment of patients with breast cancer (BC) and greatly restricts the therapeutic effect of the first-line chemotherapeutic agent doxorubicin (DOX). The present study aimed to investigate the feasibility of the recombinant dual-target murine double minute 2 (MDM2) and murine double minute X (MDMX) inhibitor in reversing the DOX resistance of BC. Both DOX-resistant human breast carcinoma cell lines exhibited a multidrug resistance (MDR) phenotype. The ability of the dual-target MDM2/MDMX inhibitor in reversing doxorubicin resistance was subsequently verified, (9....

GSE124655 FOXA1 upregulation promotes enhancer and transcriptional reprogramming in endocrine-resistant breast cancer RNA-seq
Contributors : Xiaoyong Fu ; Rachel Schiff ; Rinath Jeselsohn ; Myles BrownSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensForkhead box A1 (FOXA1) is a pioneer factor that facilitates chromatin binding and function of lineage-specific and oncogenic transcription factors. Here, we have demonstrated that FOXA1 overexpression in estrogen receptor-positive breast cancer cells drives genome-wide enhancer reprogramming to activate pro-metastatic transcriptional programs. We have identified the hypoxia-inducible transcription factor HIF-2 α as the top FOXA1-engaged super-enhancer target ind...

miR-452 promotes the development of gastric cancer via targeting EPB41L3
In this study, we found that miR-452 was highly expressed in both tumor tissue and gastric cancer cells, and could directly target the cancer suppressor gene EPB41L3 3′-UTR. miR-452 significantly promoted the proliferation, migration and the S-phase arrest of gastric cancer cells, but EPB41L3 as a downstream target gene of miR-452 reversed such promoting effect. While down-regulation of miR-452 expression significantly inhibited the malignant biological behavior of gastric cancer cells, but this inhibitory effect was reversed by EPB41L3 siRNA. In addition, miR-452 in the gastric cancer xenograft model in nude mice could ...

Neuraminidase 1 regulates proliferation, apoptosis and the expression of Cadherins in mammary carcinoma cells.
Abstract The link between Neuraminidase 1 (Neu1) and cancer development has been highlighted in numerous studies. In an effort to understand the role of Neu1 in mammary carcinoma cells, we evaluated the effect of Neu1 on controlling cell proliferation and apoptosis, as well as regulating the expression of cadherins. By blocking the activity of Neu1 with oseltamivir phosphate or using siRNA to silence the Neu1 protein, we observed suppression of cell growth in MCF-7 and MDA-MB-231 cells. Enhanced cleaved caspase 3 expression was demonstrated in breast cancer cells treated with oseltamivir phosphate or in Neu1 knock...

Cytochrome c1 as a favorable prognostic marker in estrogen receptor-positive breast carcinoma.
CONCLUSION: These results suggest that CYC1 inhibits cell proliferation, glycolytic activity and increases chemosensitivity to paclitaxel in ER-positive breast carcinoma cells and that CYC1 status is a potent favorable prognostic factor in ER-positive breast cancer patients.

DDR1 and MT1-MMP Expression Levels Are Determinant for Triggering BIK-Mediated Apoptosis by 3D Type I Collagen Matrix in Invasive Basal-Like Breast Carcinoma Cells
In conclusion, and in agreement with the other studies (Ford et al., 2007; Koh et al., 2015; Toy et al., 2015; Takai et al., 2018), our data suggest that during the acquisition of mesenchymal features, the level of full-length DDR1 expression should be considered, in addition to the other markers, as an important biomarker in the prognosis of aggressive breast carcinomas. As summarized in Figure 9, the regulation of cell proliferation and apoptosis by the collagen/DDR1 axis involves a differential activation of DDR1 signaling pathway and thus BIK expression. In the case of the basal-like bre...

The JAK/STAT Pathway in Skeletal Muscle Pathophysiology
Conclusion and Perspectives The IL-6/JAK/STAT signaling cascade plays a dominant role in skeletal muscle pathophysiology. IL-6 autocrine, paracrine, and endocrine functions assign to its downstream effectors pivotal importance in skeletal muscle-wasting-associated diseases and other multiple system diseases where muscle acts in communication with other organs. Targeting the components of the JAK/STAT pathway recently emerged as a strategic approach for the treatment of inflammatory diseases and human cancer. This review highlights the opposite outcomes on muscle biology caused by the amount of local and systemic release ...

Inhibition of SMYD2 Sensitized Cisplatin to Resistant Cells in NSCLC Through Activating p53 Pathway
In conclusion, the present study elucidated that the activity of SMYD2 in NSCLC may affect the cell sensitivity to chemotherapeutic agents, especially to CDDP. The elevated SMYD2 mediated CDDP resistance and malignant phenotype in NSCLC, indicating that SMYD2 may be a useful biomarker of CDDP resistance in NSCLC. Inhibition of SMYD2 contributes to the methylation-related activation of p53 and thus results in cell apoptosis. Furthermore, combination treatment with CDDP and an SMYD2 inhibitor had a synergistically antitumor effects in a xenograft model in vivo. Given that SMYD2 has reversible effects and is a targetable prot...

An Ensemble Strategy to Predict Prognosis in Ovarian Cancer Based on Gene Modules
Conclusion Considering the heterogeneity and complexity of ovarian cancer, we demonstrated a new method to predict the prognosis of ovarian cancer based on the clustering information and gene co-expression network in each subtype of cancer patients. We divided the ovarian cancer data into three subtypes by clustering analysis and we found that the survival risks in these three subtypes were significantly different. We mined the important communities based on the co-expression networks in each subtype. There are 50, 73, and 92 communities in the first, second and third subtype, respectively. Next, we constructed a new ense...

Endothelial Cell-Derived TGF- β Promotes Epithelial-Mesenchymal Transition via CD133 in HBx-Infected Hepatoma Cells
Conclusion: The study indicates that secretory factors like TGF-β from neighboring endothelial cells may enhance expression of CD133 and impart an aggressive EMT phenotype to HBx-infected hepatoma cells in HBV induced HCC. Introduction Hepatocellular Carcinoma (HCC) is one of the most common cancer worldwide, representing approximately 4% of all malignancies (1). It has been estimated that more than 50% of HCC cases in the world are associated with hepatitis B virus (HBV) (2). HBV is a partially double stranded DNA virus belonging to the Hepadnavirus family. The HBV genome is 3.2 kb in size and contains fou...
