2004 APR 1 - (NewsRx.com & NewsRx.net) -- Polo-like kinase 1 is a viable target for the treatment of prostate cancer.
"Second only to skin cancer, cancer of the prostate gland (CaP) is the most commonly occurring cancer in American men. Existing treatment approaches and surgical intervention have been unable to effectively manage this dreaded cancer; therefore, efforts are ongoing to explore novel targets and strategies for the management of CaP. A complete understanding of the genetic control of the processes of cellular proliferation and programmed cell death, or apoptosis, may provide the basis for the rational design of novel therapeutic strategies against CaP," scientists writing in the FASEB Journal report.
"Key regulators for the mitotic progression in mammalian cells are the polo-like kinases (Plks). The activity of Plk1 is elevated in tissues and cells with a high mitotic index, including cancer cells. An increasing body of evidence suggests that the level of Plk1 expression has prognostic value for predicting outcomes in patients with some cancers such as lung cancer, squamous cell carcinomas of the head and neck, melanomas, and ovarian and endometrial carcinomas," according to N. Ahmad and colleagues, University o Wisconsin, Medical Science Center.
"However, the role of Plk1 in CaP is not known. Here, a hypothesis is put forward that Plk1 plays a critical role in the development ...
