Tracing Parkinson's lethal mechanism
...he researchers studied the mechanism of PD using a mouse
model of the disease, in which a mitochondria-affecting toxin called MPTP is used to produce Parkinsons-like brain pathology. In earlier studies, they had found that MPTP activates protein-snipping enzymes called calpains in mitochondria. They also f...

Researchers discover method for identifying how cancer evades the immune system
...They studied the expression of these genes in five mouse
tumor models for breast cancer, leukemia, colon cancer, lung cancer and renal cell carcinoma. They then compared two of these immune signatures with corresponding human tumors, eight cases of human ductal carcinoma and 11 cases of colorectal cancer. ...
