BACKGROUND In previous papers we demonstrated that the activity of short heteroretinoids as anti-proliferative and pro-apoptotic compounds was deeply linked to their heterocyclic moiety and that ionone-derived 1,5-pyrazoles had the highest anti-proliferative activity in our preliminary experiments. We then demonstrated the high and pharmacologically significant anti-proliferative and apoptotic ...

Histone deacetylase inhibitors and proteasome inhibitor are all emerging as new classes of anticancer agents. We chose TSA and PS-341 to identify whether they have a synergistic efficacy on human ovarian cancer cells. After incubated with 500 nM TSA or/and 40 nM PS-341, we found that combined groups resulted in a striking increase of apoptosis and G2/M blocking rates, no matter in A2780, cispla...

BACKGROUND The epidermal growth factor receptor (EGFR) is expressed at different levels in many cell types and found overexpressed in many cancers. EGFR expression is increased or decreased in response to extracellular stimuli. We examined the effect of increased c-Jun expression on EGFR promoter activity. MATERIALS AND METHODS We used DNAse I foot-printing analysis to determine the binding o...

one of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. one of the most described cellular defense mechanisms involved in resistance is glutathione (gsh) and in this study, the effects of cisplatin on the total intracellular gsh level (gshi) in some sensit...

UNLABELLED Angiogenesis is a critical step in tumor development, in which vascular endothelial growth factor (VEGF) is a key growth aspect. Heat shock protein 90 (HSP90), a molecular chaperone, is essential for the activity of key proteins involved in VEGF transcription. Currently, no biomarkers to predict the effect of, or monitor, HSP90 inhibition therapy in individual patients exist. (89)Zr-...

Abstract Circular RNAs (circRNAs) play important roles in cancer tumorigenesis and progression, representing prognostic biomarkers therapeutic targets. In this case, we demonstrated the role of circ-NOLC1 epithelial ovarian (EOC). Our results have shown that Circ-NOLC1 expression was higher EOC tissues than normal tissues, positively associated with FIGO stage, differentiation. Among cell lines...

We have earlier demonstrated that breast cancer and small-cell lung cancer express functional NMDA receptors that can be targeted to promote cancer cell death. Human ovarian cancer tissues and human ovarian cancer cell lines (SKOV3, A2008, and A2780) have now been shown to also express NMDA-receptor subunit 1 (GluN1) and subunit 2B (GluN2B). Seventeen ovarian cancers in two arrays were screened...

Fourier Transformed Infrared Spectroscopy (FTIR) has extensively been used for biological applications. Cisplatin is one the most useful antineoplastic chemotherapy drugs for a variety of different human cancers. One of the clinical problems in its application, which would consequently affect the therapeutic outcome of its application, is the occurrence of resistance to this agent. In this proj...

BRCA1 is a tumor suppressor which plays a crucial role in the repair of DNA double-strand breaks, and its abnormality is responsible for hereditary ovarian cancer syndrome. It has recently been reported that reduced expression of BRCA1 is also common in sporadic ovarian carcinoma via its promoter hypermethylation, and that ovarian carcinoma patients negative for BRCA1 expression showed favorabl...
