Kaposi sarcoma arises independently from multiple cells

Kaposi sarcoma is unique among cancers because most tumors grow from a small number of different cells, whereas nearly all other cancers arise from a single cell, according to a study published online July 10 in the Journal of the National Cancer Institute.

1. Penn researchers discover new mechanism for viral replication
   08-16-2007 · EurekAlert!
   Researchers have identified a new strategy that Kaposi's Sarcoma Associated Herpesvirus uses to dupe infected cells into replicating its viral genome. This is the first study to directly show that a section of viral DNA can independently draw upon proteins within a host cell to promote its own replication.

2. An AIDS-related virus reveals more ways to cause cancer, Penn researchers find
   10-08-2007 · EurekAlert!
   Researchers have shed new light on how Kaposi's Sarcoma-associated Herpes Virus subverts normal cell machinery to cause cancer. A KSHV protein called latency-associated nuclear antigen (LANA) helps the virus hide out from the immune system in infected cells. When LANA takes the place of other proteins that control cell growth, it can cause uncontrolled cell replication.

4. How actin networks are actin'
   01-02-2008 · EurekAlert!
   The Arp2/3 complex is essential for actin assembly and motility in many cell processes, and a large number of proteins have been found to bind and regulate it in vitro. A critical challenge is to understand the actions of these proteins in cells, especially in settings where multiple regulators are present.

10. Penn researchers discover new molecular path to fight autoimmune diseases
    03-06-2007 · EurekAlert!
    Multiple sclerosis, diabetes, and arthritis are among a variety of autoimmune diseases that are aggravated when one type of white blood cell, called the immune regulatory cell, malfunctions. In humans, one cause of this malfunction is when a mutation in a gene called FOXP3 disables the immune cells’ ability to function. Penn researchers have discovered how to modify enzymes that act on the FOXP3 protein, in turn making the regulatory immune cells work better.
