Can we rejuvenate? Implications of biological aging research

Son Y, Kim JR

The life history of man is summarized as a birth-aging-disease-death. Man eventually ages and dies. How long can humans live? What is aging? Why do we age? Is aging inevitable?...

Significance of Cellular Senescence in Aging and Cancer

Grimes A, Chandra SB

  • KMID: 1972671
  • Cancer Res Treat.
  • 2009 Dec;41(4):187-195.
Cellular senescence is a mechanism that induces an irreversible growth arrest in all somatic cells. Senescent cells are metabolically active but lack the capacity to replicate. Evolutionary theories suggest that...

How Does Obesity and Physical Activity Affect Aging?: Focused on Telomere as a Biomarker of Aging

Shin YA

Obesity is known to continuously increase systemic inflammation and oxidative stress, leading to shorter telomere length. However, research regarding the correlation between physical activity, exercise, obesity, and telomere length is...

Cellular Senescence in Arterial Diseases

Shimizu I, Minamino T

Cell-proliferation potency is limited, as cells cannot proceed through the cell cycle continually. Instead, they eventually show an irreversible arrest of proliferation, commonly referred to as cellular senescence. Following the...

Age-related decline in expression of calnexin

Choi BH, Kim JS

  • KMID: 1123772
  • Exp Mol Med.
  • 2004 Oct;36(5):499-503.
Aging is accompanied by the changes in the cells that decrease their capacity to respond to various forms of stress. Cells are known to respond to stresses through expression of...

Caveolin-1 is involved in high glucose accelerated human glomerular mesangial cell senescence

Feng X, Gao W, Li Y

BACKGROUND/AIMS:: We demonstrated the role of caveolin-1 involved in high glucose (HG)-induced glomerular mesangial cells (GMCs) senescence. METHODS:: HG was used to stimulate GMCs. The telomere lengths were analyzed by Southern...

Biliverdin reductase A in the prevention of cellular senescence against oxidative stress

Kim SY, Kang HT, Choi HR, Park SC

Biliverdin reductase A (BLVRA), an enzyme that converts biliverdin to bilirubin, has recently emerged as a key regulator of the cellular redox cycle. However, the role of BLVRA in the...

The Role of Cellular Senescence in the Gastrointestinal Mucosa

Penfield J, Anderson M, Lutzke L, Wang KK

Cellular senescence is a biologically irreversible state of cell-growth arrest that occurs following either a replicative or an oncogenic stimulus. This phenomenon occurs as a response to the presence of...

Characterization of Senescence of Culture-expanded Human Adipose-derived Mesenchymal Stem Cells

Legzdina D, Romanauska A, Nikulshin , Kozlovska , Berzins U

BACKGROUND AND OBJECTIVES: Adipose-derived mesenchymal stem cells (ADSCs) are promising candidates in regenerative medicine. The need for in vitro propagation to obtain therapeutic quantities of the cells imposes a risk...

  • KMID: 2338398
  • J Korean Geriatr Soc.
  • 2005 Dec;9(4):301-305.
BACKGROUNDS: Although the role of testosterone in the neuroprotection is still poorly known, accumulating evidence suggests that testosterone may be an important role in neurodegenerative disease including dementia. So we...

Survive or thrive: tradeoff strategy for cellular senescence

Park SC

Aging-dependent cellular behaviors toward extrinsic stress are characterized by the confined localization of certain molecules to either nuclear or perinuclear regions. Although most growth factors can activate downstream signaling in...

Tenovin-1 Induces Senescence and Decreases Wound-Healing Activity in Cultured Rat Primary Astrocytes

Bang M, Ryu O, Kim DG, Mabunga DF, Cho KS, Kim Y, Han SH, Kwon KJ, Shin CY

Brain aging induces neuropsychological changes, such as decreased memory capacity, language ability, and attention; and is also associated with neurodegenerative diseases. However, most of the studies on brain aging are...

Cross-talk between BubR1 expression and the commitment to differentiate in adipose-derived mesenchymal stem cells

Lee J, Lee CG, Lee KW, Lee CW

BubR1 mitotic checkpoint kinase monitors attachment of microtubules to kinetochores and links regulation of the chromosome-spindle attachment to mitotic checkpoint signaling. Defects in BubR1-mediated signaling severely perturb checkpoint control and...
