Research Team for Geriatric Pathology, Tokyo Metropolitan Institute of Gerontology, Itabashi ku, Tokyo, Japan
Mech Ageing Dev 131:614-24. 2010..6%). Our results indicate that chromosomes having excessively shortened telomeres at late PDLs begin to show features of instability such as fusions and anaphase bridges...
Telomeric DNA length in cerebral gray and white matter is associated with longevity in individuals aged 70 years or olderKen ichi Nakamura
Research Team for Geriatric Diseases, Tokyo Metropolitan Institute of Gerontology, Tokyo, Japan
Exp Gerontol 42:944-50. 2007..Our study lends indispensable support to the hypothesis that longer telomeres protect the genome from instability (a major cause of carcinogenesis) and are beneficial for longevity...
Alcoholics show reduced telomere length in the oesophagusJunko Aida
Research Team for Geriatric Pathology, Tokyo Metropolitan Institute of Gerontology, Tokyo, Japan
J Pathol 223:410-6. 2011..Further studies to clarify the reason for the large annual loss of telomere length with rapid turnover or lower telomerase activity in the oesophageal epithelium of alcoholics will be necessary...
Accelerated in vivo epidermal telomere loss in Werner syndromeNaoshi Ishikawa
Research Team for Geriatric Pathology, Tokyo Metropolitan Institute of Gerontology, Tokyo 173 0015, Japan

Cellular Signaling Research Group, Tokyo Metropolitan Institute of Gerontology, 35 2 Sakaecho, Itabashi ku, Tokyo 173 0015, Japan
J Bioenerg Biomembr 35:41-7. 2003..Consequently, we propose a hypothesis that NDP kinases might act like a molecular switch to determine the cell fate toward proliferation or differentiation in response to environmental signals...
