... also report Nodal expression in breast cancer and testicular cancer) regain the ability to express a potent embryonic morphogen like Nodal, the presence of the Nodal and the signals it sends and receives appear to play a key role in tumor cell plasticity and progression. Most noteworthy, Dr. Hendrix’s tea...

Firefighters face increased risk for certain cancers

..., that firefighters are twice as likely to develop testicular cancer and have significantly higher rates of non-Hodgkin's lymphoma and prostate cancer than non-firefighters. The researchers also confirmed previous findings that firefighters are at greater risk for multiple myeloma. Grace LeMasters, PhD, Ash ...

Exposure to dioxins influences male reproductive system, study of Vietnam veterans concludes

...most 50 percent, a three- to four-fold increase in testicular cancer, an increase in the incidence of cryptorchidism (undescended testes, a condition where the testes are not in their normal location in the scrotum) and hypospadias (abnormality of the urethra). The reason for this increase is not known, but...

One big biology question solved

...ch has suggested a possible cause for these common testicular cancers, opening up avenues of investigation which will hopefully one day lead to a cure," Professor Koopman said. The findings of the team will be published in one of the world's top scientific journals Science and will be available in its online ...

VCU Massey Cancer Center researchers identify a new class of anti-cancer drugs based on platinum

...drug that is given for the treatment of metastatic testicular or ovarian cancers, and some advanced bladder cancer, and is a very effective drug in combination with other therapies. However, according to Farrell, these current agents have limited activity against many common human cancers, and they are suscep...

Basic research leads to a novel cancer therapy

...an cancer, pancreatic cancer, prostate cancer, and testicular cancer. The studies are in various stages of clinical trials (phases I through III), and most of them are being carried out in combination with other therapies.

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...es, infertility and possibly cancer (in particular testicular cancer). By developing suitable tests with embryonic stem cells as they differentiate to germ cells we can investigate the action of these chemicals in the laboratory. "Ultimately it might be possible to produce sperm and eggs for use in assisted co...

Researchers discover mechanism for multiplying adult stem cells

...ugh Oct4 is known to be active in certain forms of testicular and ovarian cancer. Still, the most provocative finding was that "Oct4 causes tumors by preventing adult stem cells in these tissues from differentiating," says Hochedlinger. In other words, with Oct4 active, the stem cells could replicate themselves...
