Angiocidin also shown to stimulate the body’s immune system

Angiocidin, a tumor-inhibiting novel protein discovered by Temple University researchers, may also have a role as a new therapeutic application in treating leukemia, according to a study by the researchers.

A new fundamental mechanism of how tumour cells communicate has just been discovered by the team of Dr. Janusz Rak at the Research Institute of the McGill University Health Centre (MUHC) in collaboration with Dr Guha from the University of Toronto. The cancer cells are able to communicate with their more healthy counter-parts by releasing vesicles. These bubble-like structures contain cancer-causing (oncogenic) proteins that can trigger specific mechanisms when they merge into non or less-malignant cells. These findings could change our view on how cancerous tissues work and lead to major clinical innovations. They were published on April 20 in the on-line edition of Nature Cell Biology.

Tissues derived from embryonic stem (ES) cells could help to pacify the immune system and so prevent recipients from rejecting them, the UK National Stem Cell Network Science Meeting will hear today (11 April). Speaking at the conference in Edinburgh, Dr Paul Fairchild from the University of Oxford will tell delegates that although tissues derived from ES cells succumb to rejection, they have an inherent immune-privilege which, if exploited, could have far reaching implications for the treatment of conditions such as diabetes, heart attacks and Parkinson’s.

KGK Synergize Inc. presents findings today
A new study presented at the Experimental Biology Annual Meeting shows that a proprietary blend extracted from canola, Dermytol™, produces a pronounced reduction of malignant melanoma cell growth. Dermytol™, a proprietary compound developed by KGK Synergize Inc., a biotechnology company in Ontario Canada, is designed to protect skin cells from damage that may lead to skin cancer.

When faced with cancer, the immune system dispatches cells, called T cells, to kill the tumor. But these killer cells often fail to completely eliminate the tumor because they’re deactivated by a distinct population of T cells known as regulatory T cells. Past attempts to get rid of these regulatory T cells have largely failed, in part because they share many features with the killer T cells, making it difficult to eliminate one population without also eliminating the other.

The article published in volume 14 issue 6 of World Journal of Gastroenterology reports on one patient who presented to Dr Cosimo Sperti of University of Padua, Padova, Italy, in 2001 after an exploratory laparotomy performed in another hospital for an unresectable pancreatic cystic mass that had infiltrated the portal vein. Total pancreatectomy together with resection and reconstruction of portal vein was then successfully performed. Histopathologic examination showed a solid-pseudopapillary tumor of the pancreas infiltrating the layer of the portal vein.

Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasively

A hormone secreted by cells throughout the body and known to play a role in cardiovascular disease and other cell functions is also critical for proper formation of the lymphatic system in mice, according to research from the University of North Carolina at Chapel Hill School of Medicine.
