NZ51, a ring-expanded nucleoside analog, inhibits motility and viability of breast cancer cells by targeting the RNA helicase DDX3.

DDX3X (DDX3), a human RNA helicase, is over expressed in multiple breast cancer cell lines and its expression levels are directly correlated to cellular aggressiveness. NZ51, a ring-expanded nucleoside analogue (REN) has been reported to inhibit the ATP dependent helicase activity of DDX3. Molecular modeling of NZ51 binding to DDX3 indicated that the 5:7-fused imidazodiazepine ring of NZ51 was incorporated into the ATP binding pocket of DDX3.

Characterization of vitamin-cisplatin-loaded chitosan nano-particles for chemoprevention and cancer fatigue.

Context: Vitamins have been shown to reduce chemotherapy-related fatigue (CRF) by conserving energy loss both during and after cancer treatment. However, it remains unknown whether this reduction of fatigue interferes with the cancer drugs or alters the effectiveness of these agents.

Ketorolac salt is a newly discovered DDX3 inhibitor to treat oral cancer.

DDX3 belongs to DEAD box RNA helicase family and is involved in the progression of several types of cancer. In this work, we employed a High Throughput Virtual screening approach to identify bioactive compounds against DDX3 from ZINC natural database. Ketorolac salt was selected based on its binding free energy less than or equals to -5 Kcal/mol with reference to existing synthetic DDX3 inhibitors and strong hydrogen bond interactions as similar to crystallized DDX3 protein (2I4I).

Neuronal pentraxin 1 expression is regulated by hypoxia inducible factor-1α.

Neuronal pentraxins (NPs) are belong to sub family of long pentraxin proteins consist of neuronal pentraxin 1 (NP1), neuronal pentraxin 2 (NP2), and neuronal pentraxin receptor (NPR).

But for the last few decades it is being extensively exploited for biomedical applications.

Expression of DDX3 is directly modulated by hypoxia inducible factor-1 alpha in breast epithelial cells.

DEAD box protein, DDX3, is aberrantly expressed in breast cancer cells ranging from weakly invasive to aggressive phenotypes and functions as an important regulator of cancer cell growth and survival. Here, we demonstrate that hypoxia inducible factor-1α is a transcriptional activator of DDX3 in breast cancer cells. Within the promoter region of the human DDX3 gene, we identified three putative hypoxia inducible factor-1 responsive elements.

Neoplastic transformation of breast epithelial cells by genotoxic stress.

Background: Exposure to genotoxic stresses such as radiation and tobacco smoke can cause increased cancer incidence rate as reflected in an in depth meta-analysis of data for women and breast cancer incidence. Published reports have indicated that exposures to low dose radiation and tobacco smoke are factors that contribute to the development of breast cancer. However, there is a scarcity of information on the combinatorial effects of low dose radiation and tobacco smoke on formation and progression of breast cancer.
