Epigenetic modifications are thought to be important for gene expression changes during development and aging. However, besides the Sir2 histone deacetylase in somatic tissues and H3K4 trimethylation in germlines, there is scant evidence implicating epigenetic regulations in aging. The insulin/IGF-1...
ORGANISM(S): Caenorhabditis elegans 
Increasing evidence demonstrates influenza virus can not only affect the respiratory system, but also infect CNS and lead to CNS disorder and encephalopathy and encephalitis. Astrocytes are the most abundant cells in the CNS, which are capable of producing cytokines and neurotrophic factors and are ...
ORGANISM(S): Homo sapiens 
Two fiber tissues harvested 10 days post anthesis from upland cotton trees grown under the same green house conditions except for different seasons of the year were used for RNA extraction. Small RNA molecules under 30 bases were amplified and isolated from an agarose gel. The purified DNA was used ...
