Epigenetic drugs that have shown promise in cancer trials significantly reduce scarring in the cells of patients with scleroderma, a new study shows. Results reveal that drugs that inhibit BRD4, known to play a role in cancer, also affect fibrosis in scleroderma. Researchers tested BRD4 inhibitors on the skin fibroblasts of scleroderma patients and in mouse models of skin fibrosis, finding that the treatment stopped scarring in both human-derived cells and in animals.
Researchers in the Center of Excellence for Evolutionary Therapy at Moffitt Cancer Center have been investigating an alternative treatment approach called adaptive therapy that focuses on maintaining disease control instead of complete tumor cell elimination. In a new study published in Communications Medicine, the researchers used mathematical modeling to reveal that the spatial organization of a tumor is an important factor that governs how cells compete with one another and the effectiveness of adaptive therapy.
There is an urgent need for new and better treatments for the 3 million people who suffer from Inflammatory Bowel Disease. Since the causes of IBD remain unknown, most therapies are directed against inflammation, but a better understanding of the basic mechanisms will allow more meaningful treatment for patients. An in-depth, 10-year study of immune mechanisms by researchers at the Rutgers Robert Wood Johnson Medical School, however, may have both identified a marker of IBD as well as a potential treatment option.
According to a model created by University of Washington research professor James Anderson, a genetically predetermined limit on your immune system may be the key to why COVID-19 has such a devastating effect on the elderly.
In a new study, researchers demonstrated that the benefits of endurance exercise can vary based on the type of mutation involved in mitochondrial disease, and while the benefits of exercise outweigh the risks, the mitochondrial genetic status of patients should be taken into consideration when recommending exercise as therapy.
A cross-college collaboration at The University of Alabama in Huntsville (UAH) has developed a self-learning artificial intelligence (AI) platform that uses big data analytics to discover how new pharmaceutical drugs and various molecules work inside living cells.

To engineer proteins for specific functions, scientists change a protein sequence and experimentally test how that change alters its function. Because there are too many possible amino acid sequence changes to test them all in the laboratory, researchers build computational models that predict protein function based on amino acid sequences. Scientists have now combined multiple machine learning approaches for building a simple predictive model that often works better than established, complex methods.
