USC Stem Cell study breaks the silence on how fish and lizards regenerate hearing

A USC Stem Cell study has identified key gene regulators that enable some deafened animals, including fish and lizards, to naturally regenerate their hearing. The researchers found a class of DNA control elements known as 'enhancers' that amplify the production of a protein called ATOH1, which induces sensory cells in the inner ear.

MCG neuroscientist receives $2.3 million in funding from NIH High-Risk, High-Reward Research program

Danielle Mor, a neuroscientist at the Medical College of Georgia, has been awarded $2.3 million to study the progression of Parkinson's disease through the use of C. elegans and innovative research approaches. Her goal is to understand how misfolded proteins spread from the gastrointestinal tract to the central nervous system.

Patients with advanced bladder cancer with alterations in the FGFR3 gene respond well to investigational drug, TYRA-300

TYRA-300 shows promise in treating metastatic bladder cancer patients with FGFR3 gene mutations, achieving a 50% overall response rate and 100% disease control rate. The treatment also displays improved tolerability with lower side effects compared to existing pan-FGFR inhibitors.

USC Stem Cell mouse study sheds light on the secret to maintaining a youthful immune system

A USC Stem Cell mouse study identifies a small subset of blood stem cells as the primary driver of immune aging. The researchers found that this subset overproduces innate immune cells, leading to an age-associated imbalance and increased disease risk. By targeting this subset, the study suggests a potential therapy to delay immune agi...

Study shows that Rett syndrome in females is not just less severe, but different

Researchers found that female mouse models of Rett syndrome have a mosaic-like distribution of cells expressing wild-type and mutant MeCP2 protein, leading to dysregulated genes. The study also discovered an unusual disease progression, with females having more dysregulated genes at the pre-symptomatic stage than later on.
