When cancer takes a deadly turn: NUS study sheds a new light on cancer metastasis
The ability of cancer cells to metastasise, or spread from one part of the body to another, is one of the reasons why cancer can be extremely challenging to treat. However, the process that drives metastasis is complex and not fully understood.

New understanding of why kidney cancers become metastatic discovered by MD Anderson researchers
Researchers at The University of Texas MD Anderson Cancer have engineered a new model of aggressive renal cell carcinoma (RCC), highlighting molecular targets and genomic events that trigger chromosomal instability and drive metastatic progression.
The study, published today in Nature Cancer, demonstrates that the loss of a cluster of interferon receptor (IFNR) genes plays a pivotal role in allowing cancer cells to become tolerant of chromosomal instability. This genomic feature may be used to help clinicians predict a tumor’s potential to become metastatic and treatment resistant.

How Metastatic Cancer Causes Leaky Blood Vessels
In APL Bioengineering, researchers examine the local communication between endothelial cells and tumors cells and its effects on endothelial cell orientation. The approach uses co-cultured human umbilical vein endothelial cells and breast epithelial tumor cell lines to simulate the tumor-endothelial interaction. The group found the clockwise chirality of the hUVECs was less affected by local hormone signaling and more so by direct physical contact with tumor cells. Specific proteins on the tumor cell binding to others on endothelial cells appeared to play a role in changing the clockwise chirality of hUVECs.

A key element to slowing metastasis in ovarian cancer is understanding the mechanisms of how tumor cells invade tissues. In APL Bioengineering, biophysics researchers explain how microscopic defects in how healthy cells line up can alter how easily ovarian cancer cells invade tissue. Using an experimental model, the group found that disruptions in the normal cellular layout, called topological defects, affect the rate of tumor cell invasion.
Small Numbers of Cells in a Tumor Could Be Key Enablers of Cancer Metastasis
Just a small number of cells found in tumors can enable and recruit other types of cells nearby, allowing the cancer to spread to other parts of the body, report Georgetown Lombardi Comprehensive Cancer Center scientists. Working with their research collaborators, the scientists found that ‘enabler cells’ comprise about 20 percent or less of the cells in an aggressive tumor; their small numbers may account for why they are often missed when bulk tissue analyses are used to inform therapeutic decisions.
Ludwig Cancer Research Study Shows Pancreatic Cancer Cells Hit Reverse to Advance in Malignancy
A Ludwig Cancer Research study has identified a previously unrecognized mechanism by which cancer cells of a relatively benign subtype of pancreatic tumors methodically revert—or “de-differentiate”—to a progenitor, or immature, state of cellular development to spawn highly aggressive tumors that are capable of metastasis to the liver and lymph nodes.

Johns Hopkins Kimmel Cancer Center investigators report they have uncovered a new mechanism by which invasive breast cancer cells evade the immune system to metastasize, or spread, to other areas of the body. They propose that therapies targeting this process could be developed to halt or prevent metastasis and reduce breast cancer deaths.
Breast cancer cells turn killer immune cells into allies
Researchers at Johns Hopkins University School of Medicine have discovered that breast cancer cells can alter the function of immune cells known as Natural killer (NK) cells so that instead of killing the cancer cells, they facilitate their spread to other parts of the body. The study, which will be published July 9 in the Journal of Cell Biology (JCB), suggests that preventing this reprogramming might stop breast cancer from metastasizing to other tissues, a major cause of death in breast cancer patients.
Predicting Cancer Behavior Requires Better Understanding of Tumor Cells
Our ability to predict who will get cancer, how patients will respond to treatment, or if patients will relapse is still quite limited, despite advances in the detection of genetic mutations and the establishment of risk factors; recently researchers were inspired to find new ways of looking at the problem. In Biomicrofluidics, they report that using cellular mechanophenotyping, along with traditional methods such as immunostaining and genetic analysis, may provide a more comprehensive view of a tumor.
