NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

New York University biologists have uncovered how the innate immune system in mice's brains fights viral infection of neurons. The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages--by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brai...

NYU researchers simulate molecular biological clock

For many years, DNA and proteins have been.viewed as the real movers and shakers in genomic studies, with RNA seen.as little more than a messenger that shuttles information between the.two. But researchers from Whitehead Institute for Biomedical Research.and Massachusetts Institute of Technology have discovered that small.RNA molecules called microRNAs regulate thousands of human genes--more.than...

NYU and MSKCC research provides model for understanding chemically induced cancer initiation

A team from the chemistry and biology departments of New York University, in collaboration with Memorial Sloan Kettering Cancer Center (MSKCC), has uncovered a conformational switch--a change in shape in a carcinogen-damaged DNA site--in tumor suppressor genes altered by a known cancer-causing chemical found in cigarette smoke. This finding may open new horizons for understanding the initiation o...

NYU, Rockefeller researchers find complexity of regulation by microRNA genes

Collaborating researchers at New York University and Rockefeller University have discovered that microRNA genes, which have recently been shown to have key roles in gene regulation, can team up and regulate target genes in mammals. MicroRNAs are a recently discovered large class of regulatory, non-coding genes, which bind to partially complementary sites in target messenger RNA to regulate their...

NYU chemists use computer simulation to enhance understanding of DNA transcription

New York University chemists have employed a computer simulation whose results have enhanced scientific understanding of the DNA transcription process. The study, funded by the National Institutes of Health, appears in the June 7 issue of the Proceedings of the National Academy of Sciences. . Previous research has indicated that chromatin--a chromosome's substance consisting of histone proteins a...

NYU biologists map out early stages of embryo formation

A team of genomic researchers headed by biologists at New York University's Center for Comparative Functional Genomics, in collaboration with researchers at Harvard University, the Max Planck Institute, and Cenix Biosciences, has mapped out a preliminary molecular diagram of the early stages of embryo formation, offering for the first time a global look at how a single cell begins its path into a...

NYU researchers decorate virus particles, showing potential to enhance MRI capabilities

Researchers at New York University have made chemical modifications to nanometer sized virus particles--a process that has the potential to improve magnetic resonance imaging (MRI) techniques. Their results are reported in the latest issue of Nano Letters. . The study was conducted jointly by NYU's Department of Chemistry and the Department of Radiology at the NYU School of Medicine. The study is...

NYU algorithm enhances ability to detect cancer genes

Researchers at New York University's Courant Institute of Mathematical Sciences have developed a new algorithm that enhances the ability to detect a cancer gene, and have applied their algorithm to map the set of tumor-suppressor genes involved in lung cancer. The algorithm uses data from Affymetrix's gene-chips that can scan hundreds of patients' genomes to find gains and losses in gene-copies....

NYU biologists identify gene that coordinates two cellular processes

A team of biologists at New York University's Center for Comparative Functional Genomics has uncovered a dual role for the gene mel-28. The gene plays a part in ensuring that chromosomes are divided properly during cell division and it is required for nuclear envelope function. The findings appear in the journal Current Biology. . The team is using functional genomic tools to study the nema...

NYU scientists identify how development of different species uses same genes with distinct features

Biologists at New York University have identified how different species use common genes to control their early development and alter how these genes are used to accommodate their own features. The findings, which were discovered by researchers in Professor Claude Desplan’s and Steve Small’s laboratories in NYU’s Center for Developmental Genetics, offer new insight into the workings of developmen...
