The Cellular Mechanisms in Aging and Development [CMAD] Study Section reviews applications that use a range of approaches and vertebrate/invertebrate model organisms to address fundamental biological questions regarding the processes of aging. These include genetic, genomic, cellular, molecular, developmental, biochemical, metabolic and physiologic mechanisms that regulate healthspan and lifespan.

Review Dates

Membership Panel

The membership panel is a list of chartered members only.

Topics


  • Genetic, molecular, epigenetic, and developmental regulation of aging and longevity.
  • Metabolic and physiologic regulation of healthspan and lifespan: caloric/dietary restriction; nutrient sensing/signaling; cross talk among tissues to affect organismal longevity; mammalian target of rapamycin pathways; systems biology; circadian clocks and aging; microbiome.
  • Mitochondrial function/dysfunction in aging.
  • Genome surveillance, proteostasis and aging: oxidative damage; antioxidant defenses; stress responses; DNA damage/repair; telomere dysfunction; epigenetic clocks; protein damage/misfolding/aggregation and proteasome-mediated degradation; autophagy; apoptosis.
  • Replicative/cellular senescence and aging: senescence associated secretory phenotype (SASP); inflammaging; senolytics and other strategies to target senescent cells in animal models.
  • Tissue/organ aging, regeneration and repair: roles of adult stem cells in replacement/repair of aging/damaged tissue; aging of stem cells and their niche; aging of tissue microenvironment; sarcopenia; neurodegeneration.
  • Aging and cellular plasticity.
  • Progeroid syndromes: Werner Syndrome, Hutchinson Gilford Progeria Syndrome; laminopathies
  • Interventions that impact longevity and healthy aging: drugs, dietary supplements, nutraceuticals, diets, exercise.
  • Basic molecular and cellular mechanisms driving geroscience.

Shared Interests and Overlaps

CMAD  and ASG have shared interests in many areas. CMAD reviews applications pertaining to fundamental biological questions on mechanisms of aging that regulate healthspan and lifespan whereas ASG focuses on clinical aspects of geroscience and geriatrics. ASG generally reviews human subjects, whereas CMAD generally reviews applications using animal models. Applications using non-human primates will be assigned on a case-by-case-basis, depending on emphasis.

There are shared interests with Pathophysiology of Obesity and Metabolic Disease (POMD) in metabolic regulation. Applications studying metabolic regulation in response to dietary changes are reviewed in POMD. Applications about the dietary/caloric restrictions to regulate metabolism in extending lifespan are assigned to CMAD

There are shared interested with SMEP  in the investigation of metabolic and physiologic regulation of aging muscle.  Grant applications that focus on nutrient sensing or signaling, mammalian target of rapamycin (mTOR), sirtuins, insulin/IGF/GH pathways and mitochondria function with specific focus to study metabolic and physiologic mechanisms that regulate aging may be assigned to CMAD.  Applications on sarcopenia as well as aging of skeletal muscle stem cells and their niche may also be assigned to CMAD. Applications with primary focus on skeletal muscle biology and function and inactivity may be assigned to SMEP.

There are shared interests with CSRS in basic cellular processes such as cell proliferation and senescence, cell death, genomic stability, DNA replication and repair.  Applications about basic science of these process are reviewed in CSRS.  Studies where involvement of these processes in aging is the focus are reviewed in CMAD.

There are shared interests with MBPP in protein folding/misfolding/aggregation, autophagy.  Application about understanding basic mechanisms of these biological processes are reviewed in MBPP, but those with a focus on role of these processes in aging are reviewed in CMAD. Biogenesis and structure/ function of mitochondria are topics reviewed in MBPP, but mitochondrial dysfunction in aging may be reviewed in CMAD.

There are shared interests with NDPR. When the focus is on mechanisms and events within the nervous system, the application may be reviewed by NDPR. When the focus is on neurobiology or integrative mechanisms of aging involving the whole organism, the applications are reviewed by CMAD.
