| Whole exome sequencing predicts whether patients respond to cancer immunotherapy Posted: 08 Jul 2022 09:36 AM PDT Immunotherapies, such as immune checkpoint inhibitors, have transformed the treatment of advanced stage cancers. Unlike chemotherapies that kill cancer cells, these drugs help the body's immune system to find and destroy cancer cells themselves. Unfortunately, only a subset of patients responds long-term to immune checkpoint inhibitors -- and these treatments can come at a high cost and with side effects. Researchers have developed a two-step approach using whole exome sequencing to zero in on genes and pathways that predict whether cancer patients will respond to immunotherapy. The study, published in Nature Communications and conducted by researchers at New York University, Weill Cornell Medicine, and the New York Genome Center, illustrates how the use of whole exome sequencing can better predict treatment response than current laboratory tests. |

| Scientists use mini-kidney models to identify potential drugs for polycystic kidney disease Posted: 07 Jul 2022 11:18 AM PDT Scientists hsve generated simple kidney-like structures called organoids and used them to identify potential drugs to treat adult-onset polycystic kidney disease. To accelerate the quest for new treatments for ADPKD, researchers used pluripotent stem cells to grow organoids consisting of one or two structures resembling the kidney's filtering units, known as nephrons. To make the organoids useful for studying ADPKD, the scientists used CRISPR/Cas9 gene editing to inactivate PKD1 or PKD2. As anticipated, the gene-edited organoids began to form cysts. After testing a collection of 247 enzyme inhibitor compounds on the organoids, the scientists found nine that inhibited the growth of the cysts, without stunting the overall growth of the organoids. One compound, quinazoline, was particularly effective. |
| Mouse study links changes in microbiome to prenatal opioid exposure Posted: 07 Jul 2022 11:18 AM PDT Researchers identified significant changes to the infant gut microbiome of mice associated with maternal exposure to oxycodone, a commonly used and abused opioid. |
| Oceanographers develop new model to better predict barrier island retreat Posted: 07 Jul 2022 11:18 AM PDT Barrier islands protect the coastline from storms, storm surge, waves and flooding. They can act as a buffer between the ocean and beachfront property. As sea level rises, barrier islands retreat, or move closer toward the shore, which diminishes the buffer and protection. New information shows the retreat of coastal barrier islands will accelerate by 50 percent within a century, even if sea level continues to rise at its present rate. |
