9th July 2009 by admin 1 Comment

New drugs called PARP inhibitors appear to have a lot of promise against hereditary cancers caused by BRCA1 and BRCA2 cell mutations.
PARP inhibitors work by blocking the action of poly (ADP-ribose) polymerase, an enzyme that helps repair DNA. In certain tumor cells, such as those from BRCA1 and BRCA2 mutation carriers, blocking this enzyme can [...]

New Drug Could Work Against Leukemia

A new targeted therapy shows promise in treating acute myeloid leukemia, a highly treatment-resistant blood cancer, according to a new study.
Researchers created an antibody (7G3) that recognizes and binds to a molecule called CD123, which is expressed at high levels on leukemia stem cells (LSCs), but not on normal blood cells. LSCs are cells that [...]

Lab Study Finds Protein That May Inhibit Cancer Spread

Currently, there is no approved therapy for inhibiting or treating metastasis — the migration of cancer cells from the original cancer site to other parts of the body. Metastasis is one of [...]
