Bladder Cancer Gene Identified

LONDON (Reuters) Feb 26 - British researchers said on Thursday they had

identified a gene linked to bladder cancer that could improve the treatment

of the disease.

" This is a very exciting development. E2F3 is the missing link in our

knowledge of the disease, " said Professor Colin of Britain's

Institute of Cancer Research.

The E2F3 gene is involved in controlling the division of human cells.

and his colleagues, reporting in the journal Oncogene, found that

overexpression of E2F3 was associated with cell proliferation and the

development of bladder cancer.

When they measured the amount of E2F3 protein in bladder cancer cells in

laboratory tests they found it corresponded to the grade or seriousness of

the tumour. Grade 1 bladder cancer cells had smaller amounts of the protein,

while cells of a higher grade had increased levels.

" These findings will boost the development of new treatments to target

bladder cancer as well as predicting the aggressiveness of a particular

cancer, leading to tailor-made, more effective treatments for each

individual patient, " said in a statement.

Bladder cancer is the ninth most common cancer worldwide. The disease kills

about 130,000 people worldwide each year and 330,000 new cases are reported

annually.

Smoking is the single most important cause of bladder cancer, accounting for

65 percent of male cases and 30 percent of female cases, according to the

International Agency for Research on Cancer in Lyon, France.
