In the past years, the results gained in the treatment of sarcomas have encouraged the research group to apply their knowledge to...Tiny tweezers and yeast help St. Jude show how cancer drug works
...thesize exact copies of each chromosome. Topotecan exploits the binding of topoisomerase I to double-stranded DNA that occurs when the cell tries to separate these strands. Researchers already knew that topotecan poisons topoisomerase by binding to both the enzyme and to the nicked, single strand of DNA. Th...In new statistical approach, data decide model
