Using a nanoparticle that manages a drug and then lights when green cancer the cells begin to die, researchers of Indian origin have found a way to detect the effectiveness of cancer treatment much earlier than clinical methods currently available. Being able to detect early whether a cancer therapy is working for a patient can influence the course of treatment and improve outcomes and quality of life. However, conventional detection methods – such as PET scans, CT and MRI – usually can not detect if a tumor is shrinking until the patient has received multiple cycles of treatment. The new approach can read about the effectiveness of chemotherapy in just eight hours after treatment, and can also be used to monitor the effectiveness of immunotherapy, according to the study. “With this approach, the cells light up the time a cancer drug starts working. Can determine if a cancer treatment is effective within hours of treatment, “he said co-author corresponding Shiladitya Sengupta at Brigham and Women’s Hospital in Boston, Massachusetts, United States (Read:.

“Our long-term goal is to find a way to monitor the results very early so we do not give a chemotherapy drug for patients not respond to it, “Sengupta said. the findings were published online in the journal Proceedings of the National Academy of Sciences. the new technique takes advantage of the fact that when cells die, a particular enzyme known as activated caspase. the researchers designed a “reporter element which, when in the presence of activated caspase lights green. The team then tested whether they could use the reporter to distinguish between drug-sensitive tumors and drug-resistant nanoparticles. This is everything you need to know about the latest advances in cancer treatment .
Use of nanoparticles loaded with anticancer drugs, the team tested a common chemotherapeutic agent, paclitaxel, in a pre-clinical prostate cancer model and, separately, an immunotherapy in a preclinical model of melanoma. In tumors that were sensitive to paclitaxel, the computer was an increase of about 400 percent of the fluorescence compared to tumors that were not sensitive to the drug. The equipment also saw a significant increase in fluorescent signal in tumors treated with nanoparticles anti-PD-L1 after five days. “We have shown that this technique can help us to directly visualize and measure the responsiveness of tumors to both types of drugs,” co-corresponding author Ashish Kulkarni, BWH, he said.
