Abstract

Isothiocyanates derived from the Brassicaceae plants possess chemopreventive and anticancer activities. One of them is sulforaphene (SF), which is abundant in Rhapanus sativus seeds. The underlying mechanism of its anticancer activity is still underexplored. SF properties make it an interesting candidate for cancer prevention and therapy. Thus, it is crucial to characterize the mechanism of its activity. We investigated the mechanism of antiproliferative activity of SF in breast cancer cells differing in growth factor receptors status and lacking functional p53. Viability of SKBR-3 and MDA-MB-231 breast cancer cells treated with SF was determined by SRB and clonogenic assays. Cell cycle, cell death and oxidative stress were analyzed by flow cytometry or microscopy. The levels of apoptosis and autophagy markers were assessed by immunoblotting. SF efficiently decreased the viability of breast cancer cells, while normal cells (MCF10A) were less sensitive to the analyzed isothiocyanate. SF induced G2/M cell cycle arrest, as well as disturbed cytoskeletal organization and reduced clonogenic potential of the cancer cells. SF induced apoptosis in a concentration-dependent manner which was associated with the oxidative stress, mitochon...Continue Reading

Autophagy & Metabolism

Autophagy preserves the health of cells and tissues by replacing outdated and damaged cellular components with fresh ones. In starvation, it provides an internal source of nutrients for energy generation and, thus, survival. A powerful promoter of metabolic homeostasis at both the cellular and whole-animal level, autophagy prevents degenerative diseases. It does have a downside, however--cancer cells exploit it to survive in nutrient-poor tumors.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Autophagy & Model Organisms

Autophagy is a cellular process that allows degradation by the lysosome of cytoplasmic components such as proteins or organelles. Here is the latest research on autophagy & model organisms

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
