Research discovers new drug target for metastatic breast cancer
04/11/2013 - 10:23

Research led by Dr. Suresh Alahari, Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, is the first to report that two specific tumor suppressor genes work in concert to inhibit the growth and spread of breast tumor cells to the lungs. The research is published this week online in the Journal of Biological Chemistry.

Trackable drug-filled nanoparticles - a potential weapon against cancer
03/04/2013 - 10:11

Tiny particles filled with a drug could be a new tool for treating cancer in the future. A new study published by Swedish scientists in Particle & Particle Systems Characterization shows how such nanoparticles can be combined to secure the effective delivery of cancer drugs to tumour cells - and how they can be given properties to make them visible in MR scanners and thus rendered trackable.

Pathway Identified in Human Lymphoma Points Way to New Blood Cancer Treatments
11/21/2012 - 16:36

A pathway called the “Unfolded Protein Response,” or UPR, a cell’s way of responding to unfolded and misfolded proteins, helps tumor cells escape programmed cell death during the development of lymphoma.

World's fastest camera, created by UCLA engineers, used to detect rogue cancer cells
07/05/2012 - 20:56

The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments. Circulating cancer tumor cells are a perfect example. Typically, there are only a handful of them among a billion healthy cells, yet they are precursors to metastasis, the spread of cancer that causes about 90 percent of cancer mortalities. Such "rogue" cells are not limited to cancer — they also include stem cells used for regenerative medicine and other cell types.

Block its recycling system, and cancer kicks the can, according to new Penn study
05/08/2012 - 09:31

All cells have the ability to recycle unwanted or damaged proteins and reuse the building blocks as food. But cancer cells have ramped up the system, called autophagy, and rely on it to escape damage in the face of chemotherapy and other treatments. Now, researchers at the Perelman School of Medicine; the Abramson Cancer Center; and the School of Arts and Sciences, at the University of Pennsylvania, have developed a potent new drug that clogs up the recycling machinery and kills tumor cells in mouse models.
