چکیده

Over the last decades, accumulating data have advanced our understanding of the mechanism of action of tumor suppressor proteins and therapeutic strategies to restore tumor suppressor pathways have emerged as a promising approach for cancer therapy. Based on our recent findings on bridging integrator-1 (BIN1), we outline potential advantages and disadvantages of chemical activation of tumor suppressors.

Small molecule targeting miR-34a for cancer therapy

miR-34a functions as a tumor suppressor in many cancers. In a recent issue of Cancer Research, we describe a small molecule, Rubone, with strong anticancer activity. Rubone selectively restored miR-34a expression in hepatocellular carcinoma cells in which miR-34a was silenced. Restoration of miR-34a by Rubone represents a promising therapeutic approach against cancer.

Small Molecule Inhibitors of MDM2-p53 and MDMX-p53 Interactions as New Cancer Therapeutics

Inactivation of the function of tumor suppressor p53 is common in human cancers. In approximately half of human cancers, the tumor suppressor function of p53 is inactivated by deletion or mutation of TP53, the gene encoding p53 protein. In the remaining 50% of human cancers, p53 tumor suppressor function can be effectively inhibited by oncoprotein MDM2 or its homolog MDMX. Since inhibition of p...

CtBP- an emerging oncogene and novel small molecule drug target: Advances in the understanding of its oncogenic action and identification of therapeutic inhibitors

C-terminal Binding Proteins (CtBP) 1 and 2 are oncogenic transcriptional co-regulators overexpressed in many cancer types, with their expression level correlating to worse prognostic outcomes and aggressive tumor features. CtBP negatively regulates the expression of many tumor suppressor genes, while coactivating genes that promote proliferation, epithelial-mesenchymal transition, and cancer st...

Multiple Low Doses of 5-Fluorouracil Diminishes Immunosuppression by Myeloid Derived Suppressor Cells in Murine Melanoma Model

Background: Melanoma progression and metastasis is suggested to be mediated by increased accumulation of myeloid derived suppressor cells. Various chemotherapeutic drugs such as 5-Fluorouracil in single low concentration have the capacity, at least in part, to reverse tumor progression by reducing myeloid derived suppressor cellsmediated immunosuppression. Objective: To assess whether multiple ...

Molecular Dynamic Simulation Insights into the Normal State and Restoration of p53 Function

As a tumor suppressor protein, p53 plays a crucial role in the cell cycle and in cancer prevention. Almost 50 percent of all human malignant tumors are closely related to a deletion or mutation in p53. The activity of p53 is inhibited by over-active celluar antagonists, especially by the over-expression of the negative regulators MDM2 and MDMX. Protein-protein interactions, or post-translationa...
