Of note, most of the studies summarized here provide mainly descriptive evidence for an involvement of specific aging pathways in BPD.
In particular, this model organism develops an array of senescence symptoms resembling those in humans [61] [62] [63] [44], and is amenable to large-scale genetic screens that can be targeted to conserved aging pathways in vertebrates [42].
There has, however, been little direct evidence that this is true in normal human aging and age-related disease, and the role of canonical aging pathways in human age-related pathologies has not been established.
A principle component analysis of these shared GO terms using REViGO term clustering and analysis further indicated the presence of shared canonical aging pathways in the 5 age-related disease categories (Fig. S2, Supporting information).
Until now, acetylation had not been directly implicated in the aging pathway, so this is a new role and potential target for prevention or treatment strategies, the researchers said.
Zebrafish show an array of senescence symptoms resembling those in humans, which can be targeted to specific aging pathways conserved in vertebrates.
This novel aging model, which allows efficient large-scale isolation of old cells, may facilitate biochemical characterizations and genomics/proteomics studies of cellular aging, and help to verify the aging pathways observed in other organisms including S. cerevisiae.
We propose that early alterations in major aging pathways drive premature aging of the lung thereby adding to the risk for development of chronic lung diseases later in life [9, 10].
As described in this issue of Aging, mTOR pathway is involved in glycolytic phenotype, causing self-poisoning due to over-production of lactic acid.
Several studies focused on the pattern of transcriptional factors on aging tissues found that overactivation of the I kappa B kinase- (IKK-) NF- κB pathway is one of the signatures of aging, revealing the inflammatory pathways in aging [ 37, 38].
