Dr. Mani Mahadevan's research focuses on understanding the molecular mechanisms underlying DM1, a genetic disorder causing progressive muscle weakness and disability. His team has developed a mouse model to study toxic RNA production, which may lead to a viable treatment for the disease.
High doses of lithium-like drugs inhibit GSK-3 beta and impair neuronal growth in mouse neurons, contradicting previous findings that suggest these drugs improve neuronal function. Researchers warn that using too much of these inhibitors can be detrimental to Alzheimer's treatment.
University of Wisconsin-Madison researchers discovered novel functions of the Sen1 protein, which acts as a master regulatory switch in yeast. This discovery may help understand human neurodegenerative diseases like ALS and movement disorders.
A team of researchers has developed a new method for targeting malignant brain tumors by inducing cancerous cells to commit suicide. The technique uses a molecule containing long, double-stranded RNA attached to epidermal growth factor (EGF) and delivered selectively to cells with high EGF receptors.
Researchers discovered that APOBEC3G forms large RNA protein complexes to block HIV and protect against jumping genes. This finding may lead to new approaches for controlling HIV infection.
Research suggests that HIV RNA levels have limited value in predicting CD4 cell count decrease and may not be a reliable marker for disease progression. The study found that only 4-6% of the rate of CD4 cell decline can be explained by presenting plasma HIV RNA level.
Researchers at the University of Virginia Health System have successfully reversed myotonic muscular dystrophy in mice by removing toxic RNA from muscle cells. The disease causes progressive muscle wasting and other symptoms in about 40,000 people worldwide.
Researchers have discovered the structure of a protein called nucleoprotein, which helps viruses like rabies evade the human immune system. The protein acts as a 'clamp' to protect the virus RNA from degradation by host enzymes.
A new study reveals that arthropod mitochondrial genomes exhibit nonstandard codes, including AGG translating to both serine and lysine. The research suggests that these changes may have occurred due to pairing disadvantages, potentially leading to the evolution of multiple alternative codes.
Researchers found that a protein called Y box-binding protein 1 binds to the methyl-CpG binding protein 2 (MeCP2) gene, leading to changes in alternative RNA splicing. This process can result in diverse sets of RNA and proteins being produced from the same gene.
Researchers at EMBL have discovered two types of EJC complexes that determine how NMD deals with defective RNA molecules. The presence or absence of a protein called UPF2 affects the composition of the EJC, influencing how NMD recognizes and breaks down faulty RNAs.
