TL;DR: Improved understanding of how the cytoskeleton and its interacting partners influence tumour cell migration and metastasis has led to the development of novel therapeutics against aggressive and metastatic disease.
Abstract: Metastasis is responsible for the greatest number of cancer deaths. Metastatic disease, or the movement of cancer cells from one site to another, is a complex process requiring dramatic remodelling of the cell cytoskeleton. The various components of the cytoskeleton, actin (microfilaments), microtubules (MTs) and intermediate filaments, are highly integrated and their functions are well orchestrated in normal cells. In contrast, mutations and abnormal expression of cytoskeletal and cytoskeletal-associated proteins play an important role in the ability of cancer cells to resist chemotherapy and metastasize. Studies on the role of actin and its interacting partners have highlighted key signalling pathways, such as the Rho GTPases, and downstream effector proteins that, through the cytoskeleton, mediate tumour cell migration, invasion and metastasis. An emerging role for MTs in tumour cell metastasis is being unravelled and there is increasing interest in the crosstalk between key MT interacting proteins and the actin cytoskeleton, which may provide novel treatment avenues for metastatic disease. Improved understanding of how the cytoskeleton and its interacting partners influence tumour cell migration and metastasis has led to the development of novel therapeutics against aggressive and metastatic disease.

TL;DR: New molecular insights have inspired the development of pro-apoptotic receptor agonists (PARAs), including the recombinant human protein apoptosis ligand 2/TNF-related apoptosis-inducing ligand (Apo2L/TRAIL) and agonistic monoclonal antibodies to its signalling receptors.
Abstract: Each day, the human body eliminates billions of unwanted cells by apoptotic suicide. Apoptosis provides an important barrier against cancer; however, specific mutations enable some tumour cells to escape apoptotic death and become more malignant. Two signalling pathways initiate apoptosis: one acts through intracellular Bcl-2 proteins, the other through cell-surface pro-apoptotic receptors. New molecular insights have inspired the development of pro-apoptotic receptor agonists (PARAs), including the recombinant human protein apoptosis ligand 2/TNF-related apoptosis-inducing ligand (Apo2L/TRAIL) and agonistic monoclonal antibodies to its signalling receptors. Acting alone, or in concert with other agents, PARAs may overcome key apoptosis blocks and direct cancer cells to self-destruct.

TL;DR: Therapy of metastasis should be targeted not only against tumor cells, but also against the host factors that contribute to and support the progressive growth and survival of metastatic cancer cells.

TL;DR: A striking difference in the expression of exogenously introduced retroviral genes in various colorectal cancer cell lines was reported and was associated with DNA methylation and could be reversed by treatment with the demethylating agent 5-azacytidine.
Abstract: Apparent alterations in DNA methylation have been observed in many cancers, but whether such alterations represent a persistent alteration in the normal methylation process is not known. In this study, we report a striking difference in the expression of exogenously introduced retroviral genes in various colorectal cancer cell lines. Extinguished expression was associated with DNA methylation and could be reversed by treatment with the demethylating agent 5-azacytidine. A striking correlation between genetic instability and methylation capacity suggested that methylation abnormalities may play a role in chromosome segregation processes in cancer cells.

TL;DR: Curcumin induced apoptosis in tumor cells via a p53‐dependent pathway in which Bax is the downstream effector of p53, which suggests that this molecule could have a possible therapeutic potential in breast cancer patients.
