Specifically, the patent covers clones of any non-human mammalian species, generated from any adult or fetal somatic cell, during any phase of the cell growth cycle
Ansan has worldwide marketing rights to Pivanex, which laboratory studies indicate may halt the growth of cancer cells by regulating the cell growth cycle
and by inducing apoptosis or "programmed cell death" in malignant cells.
In previous research, MK-0457 has been successful in blocking the progression of a normal cell growth cycle
, inducing apoptosis (programmed cell death) in a range of human tumors, and inhibiting tumor growth in early leukemia models.
