New non-invasive technique could revolutionize the imaging of metastatic cancer
Bioluminescence, nanoparticles, gene manipulation – these sound like the ideas of a science fiction writer, but, in fact, they are components of an exciting new approach to imaging local and metastatic tumors. In preclinical animal models of metastatic prostate cancer, scientists at Virginia Commonwealth University Massey Cancer Center, VCU Institute of Molecular Medicine and Johns Hopkins Medical Institutions have provided proof-of-principle of a new molecular imaging approach that could revolutionize doctors’ ability to see tumors that have metastasized to other sites in the body, including the bones.
Chat on Cancer Pain Management
Recently, the National Cancer Institute hosted a Twitter chat on cancer pain. Patrick Coyne, M.S.N., A.P.R.N., F.A.A.N., clinical director of the Palliative Care Program at VCU Massey Cancer Center and world-renowned pain management specialist, provided expert commentary as the moderator posed a series of questions and discussion topics.
Promising new cancer therapy uses molecular “Trash Man” to exploit a common cancer defense
While many scientists are trying to prevent the onset of a cancer defense mechanism known as autophagy, researchers at Virginia Commonwealth University Massey Cancer Center are leveraging it in a new therapy that causes the process to culminate in cell death rather than survival. The novel treatment strategy targets the p62 protein, which is often referred to as the “Trash Man” due to its role in disposing unwanted cellular proteins during autophagy. Results from preclinical experiments suggest this experimental treatment approach could be particularly effective against multiple myeloma and potentially other forms of blood cancers.
Protein found to block benefits of vitamin A cancer therapy
Retinoic acid is a form of vitamin A that is used to treat and help prevent the recurrence of a variety of cancers, but for some patients the drug is not effective. The reason for this resistance was unclear until this week when researchers from Virginia Commonwealth University Massey Cancer Center demonstrated that a protein known as AEG-1 blocks the effects of retinoic acid in leukemia and liver cancer. Because AEG-1 is overexpressed in nearly every cancer, these findings could impact the care of countless cancer patients.
Scientists develop mouse model that could lead to new therapies for liver cancer
Researchers have created the first mouse model demonstrating the role of a cancer promoting gene, Astrocyte elevated gene-1 (AEG-1), in hepatocellular carcinoma, or liver cancer. The mouse model represents a critical step in understanding the molecular mechanisms of liver cancer progression and could lead to novel therapies for the disease.
