p53 inhibitory oligonucloeotides (SJ-09-0015)

St. Jude Reference #SJ-09-0015


Researchers led by former Cancer Center Director Michael Kastan, MD, PhD, have discovered a small DNA oligonucleotide that can be used to inhibit the induction of p53 protein following exposure to DNA damaging agents and other types of cellular stress by a unique mechanism. This oligonucleotide, which can be as small as 8-15 bases in length, has potential to protect normal tissues from toxicity during treatment with chemotherapy or radiation therapy, to protect individuals from tissue toxicity associated with unplanned radiation exposures, and perhaps to reduce tissue injury during a heart attack or stroke.
