Methotrexate induced cell death mechanisms in MCF-7 adenocarcinoma breast cancer cells: Enhanced cytotoxicity following dff45-siRNA pre-treatment
Publication date: Available online 30 August 2018Source: SynergyAuthor(s): Fatemeh Kiani, Negin Rasouli, Tahereh Kashkoolinejad, Shahrokh Safarian, Seyed Jalal Zargar, Nader SheibaniAbstractThere are many efforts to diminish risks associated with the use of cancer chemotherapeutic agents through design and utilization of new strategies including gene therapy. We previously showed knockdown of dff45 or overexpression of dff40, the important apoptosis regulators, resulted in enhanced sensitization of cancer cells to chemotherapeutic agents. Here we show that pre-treatment with dff45-siRNA additively increased the overall cyt...

Knockdown of autophagy-related protein 6, Beclin-1, decreases cell growth, invasion, and metastasis and has a positive effect on chemotherapy-induced cytotoxicity in osteosarcoma cells
Abstract Beclin-1, a well-known key regulator of autophagy, has been implicated in many disorders, including cancer, aging, and degenerative diseases. Previous studies demonstrated that Beclin-1 participated in tumorgenesis and was highly expressed in colorectal cancer cells, primary duodenal adenocarcinoma, and hepatocellular carcinoma cells, and overexpression of Beclin-1 could induce autophagic cell death in leukemia cells. However, the exact effects and molecular mechanisms of Beclin-1-mediated autophagy in osteosarcoma are still unknown up to now. Here, we evaluated the role of Beclin-1 in human osteosarcoma ...

A new strategy in the treatment of chemoresistant lung adenocarcinoma via specific siRNA transfection of SRF, E2F1, Survivin, HIF and STAT3 BASIC SCIENCE
CONCLUSIONS In our study, we emphasized that siRNA interference might represent a productive platform for further research in order to investigate whether a new regimen in the treatment of multiresistant non-small-cell lung cancer could be established in vivo in the context of a multimodal cancer therapy.

086 * A NEW STRATEGY IN THE TREATMENT OF CHEMORESISTANT LUNG ADENOCARCINOMA VIA siRNA SPECIFIC SILENCING OF SRF, E2F1, SURVIVIN, HIF AND STAT 3
Conclusions: Our study proposed a new alternative in the treatment of chemoresistant NSCLC. Via siRNA specific silencing complex an accurate suppression of various chemoresistant cell lines can be achieved. Therefore, siRNA might represent an effective transient individualized regimen in the treatment of NSCLC as well an important platform for new chemotherapeutics.
