New, improved drugs could result from first-ever transfer of DNA information from one species of streptomyces to another
...ng organism. Bleomycin is an important anti-cancer chemotherapeutic
drug that has so far been completely refractory to genetic manipulation, said Dr. Janet Westpheling, a UGA geneticist and leader of the research team. We anticipate that the ability to get DNA into this strain of Streptomyces will lead to the product...
Protective protein caps discovered at ends of human chromosomes
... altered its ability to bind DNA might provide new chemotherapeutic
agents," he said. In addition, telomere replication in the laboratory can allow for continuous proliferation, or "immortality" of human cells, so the POT-1 protein could have implications for the aging process. "Only time will tell," said Baumann....
Drug resistance found to vary by ethnicity
... cells of drugs. When working correctly, PGP pumps chemotherapeutic
drugs out of tumors, allowing the tumor cells to survive. This response is known as drug resistance. The genetic mutation means the PGP pump stops working, allowing drugs to enter and kill tumor cells. PGP also rids cells of many other medications, ...

...ulated by STAT3. The work reinforces the view that chemotherapeutic
agents inhibiting the JAK-STAT pathway might prove of considerable utility in treating LGL leukemia and perhaps other neoplasms....

Treatment protects mouse ovaries from radiation therapy
...protection would be afforded to ovaries exposed to chemotherapeutic
drugs. "For the first time we have a promising prospect for a small molecule that could be given to women and girls undergoing cancer treatment to protect their ovaries," says Jonathan Tilly, PhD, the paper's senior author. However, he notes that fu...
