How cancer prevention drives aging
For the first time, researchers have found how cellular senescence, the well-known mechanism for preventing cancer, can trigger aging and age-related disease by changing the local tissue environment. ANI
Scientists unveil genes vital to vital to adult heart function
In a study on fruit fly Drosophila, scientists at the Burnham Institute for Medical Research (Burnham) have found that genes involved in embryonic heart development are vital to adult heart function in both fruit flies and humans. ANI
Psychiatric disorders common among college-aged
A new study has revealed that psychiatric disorders appear to be common among 18- to 24-year-olds, with overall rates similar among those attending or not attending college. ANI
A study conducted by researchers at the Novartis Institute for Tropical Diseases and the Genome Institute of Singapore has identified new host genes, which are associated with dengue virus infection that might open new avenues for treatment of the disease.Dr Subhash Vasudevan and Dr. Martin Hibberds team tried to identify the ways in which humans interacted with dengue virus during infection in order to discover new treatment targets that could be exploited to control viral replication, by using micro array technology to monitor the response of virtually every human gene.
Washington, Nov 7 : A study conducted by researchers at the Novartis Institute for Tropical Diseases and the Genome Institute of Singapore has identified new host genes, which are associated with dengue virus infection that might open new avenues for treatment of the disease.Dr Subhash Vasudevan and Dr. Martin Hibberd's team tried to identify the ways in which humans interacted with dengue virus during infection in order to discover new treatment targets that could be exploited to control viral replication, by using micro array technology to monitor the response of virtually every human gene.
From the activated genes, the team identified three pathways common to in vitro and in vivo infection; the NF-kappaB initiated immune pathway, the type I interferon pathway, and the ubiquitin proteasome pathway.
In the study, the researchers found that inhibiting the ubiquitin proteasome pathway, or activating the type I interferon pathway, resulted in significant inhibition of viral replication whereas inhibiting the NF-kappaB initiated immune pathway had no effect on viral replication.
The finding suggested that drugs, which targeted the host pathways, might prove effective against dengue.
