The gene MRP4 appears to help T cells, key components of the human immune system, "pump out" certain anti-HIV drugs and may allow the development of drug-resistant strains of HIV, report a team of St. Jude Children's Research Hospital scientists in the September issue of Nature Medicine.
Two lipoprotein receptors bind to the protein made by the reelin gene (which controls development of the brain and is associated with neurodegenerative disorders), St. Jude Children's Research Hospital scientists published in today's issue of Neuron.
Scientists at St. Jude Children's Research Hospital have discovered a death signal that brings about the death of Streptococcus pneumoniae (also known as pneumococcus) - a discovery that could lead to revolutionary new treatments for the killer bacteria.
Investigators at St. Jude Children's Research Hospital have demonstrated in laboratory studies a new treatment for the pediatric eye cancer retinoblastoma that appears to be more effective than the current standard therapy, and more likely to prevent the recurrence of this cancer.
Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs), according to investigators at St. Jude Children's Research Hospital.
The Ink4c and Ptch1 genes collaborate to suppress the development of medulloblastoma, the most common pediatric brain tumor, according to investigators.
The ability of the brain to transmit and process information requires a lifelong commitment to maintaining the integrity of synapses, according to investigators at St. Jude Children's Research Hospital and colleagues in Hokkaido University School of Medicine (Japan).
Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine, according to a group of investigators.
A biochemical mechanism that cells use to cope with hypoxia (lack of oxygen) actually cooperates with a less well-known mechanism that helps increase the expression of those hypoxia-sensitive genes, according to investigators at St. Jude Children's Research Hospital.
The disruption of a molecular bridge that holds together the molecule p53 tends to destabilize this protein, allowing it to form potentially disease-causing aggregates, or "clumps," according to a study by investigators at St. Jude Children's Research Hospital.
