This study aimed to evaluate the effects of Pin1 inhibitor Juglone on proliferation, migration and the angiogenic ability of breast cancer cell line MCF7Adr. MCF7Adr cells were cultured and separately treated with Pin1 inhibitor Juglone (treatment group) and DMEM without drug (control group). The
OBJECTIVE
Investigating the effects of juglone loaded P188/phospholipid mixed micelles (J-MM) in breast cancer.
METHODS
In vitro cytotoxicity, apoptotic effects, in vivo therapeutic efficacy and toxicity were used to assess its antitumour effect. Uptake and imaging were used to evaluate the effect
Endocrine therapies, which inhibit estrogen receptor signaling, are the most common and effective treatments for estrogen receptoralpha-positive breast cancer. However, the utility of these agents is limited by the frequent development of resistance, and the precise mechanisms underlying endocrine
Trastuzumab (Herceptin) monoclonal antibody directed against HER2 receptor has been administered as a treatment for metastatic HER2 positive breast cancer. The problematic issue in treatment of HER2 positive breast cancer cells is commonly the induction of resistance to trastuzumab which might be
Pin1, a conserved eukaryotic Peptidyl-prolyl cis/trans isomerase, has profound effects on numerous key-signaling molecules, and its deregulation contributes to disease, particularly cancer. Although Pin1-mediated prolyl isomerization is an essential and novel regulatory mechanism for protein
This study investigated the nature and mechanism of juglone-induced apoptosis in the human breast cancer cell line MCF-7. The inhibitory effect of juglone on MCF-7 cell growth was evaluated by the dimethylthiazol tetrazolium assay. Morphological apoptotic changes were characterized using an inverted
Six novel 5,6-fused hybrids such as dihydrobenzofuran-quinone (4a and 4b), benzofuran-quinone (5a and 5b) and chromene-quinone (6a and 6b) of juglone based 1,4-naphthoquinones were synthesized by employing a three step protocol with the cyclisation of o-allyl phenol as the key step. The anticancer
Acquired resistance to tamoxifen (TAM) is a serious therapeutic problem in breast cancer patients. Here, we found that TAM-resistant MCF-7 cells (TAMR-MCF-7 cells) produced higher levels of vascular endothelial growth factor (VEGF) than control MCF-7 cells. Molecular analyses using reporter genes
OBJECTIVE
Clinical trials have shown efficacy of the anti-HER2 monoclonal antibody trastuzumab in metastatic breast cancer patients. The aim of the present study was to elucidate the mechanisms by which up-regulation of fatty acid synthase (FAS) expression confers resistance to trastuzumab in
Redox signaling plays a fundamental role in maintaining cell physiological activities. A deregulation of this balance through oxidative stress or nitrosative stress has been implicated in cancer. Here, we reported that 2-methoxy-6-acetyl-7-methyl juglone (MAM), a natural naphthoquinone isolated from
The HER-2 oncogene, a member of the erythroblastosis oncogene B (ERBB)-like oncogene family, has been shown to be amplified in many types of cancer, including breast cancer. However, the molecular mechanism of HER-2 overexpression is not completely understood. The phosphorylation of proteins on the
OBJECTIVE
Dipeptidyl peptidase 4 (DPP4) is an aminopeptidase that is widely expressed in different cell types. Recent studies suggested that DPP4 plays an important role in tumour progression in several human malignancies. Here we have examined the mechanisms by which up-regulation of DPP4
