Necrosis01:16

Necrosis

5.1K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

The Effect of Aging on Tissues

2.9K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Mitochondria01:37

Mitochondria

16.3K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Aging

364
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Bone Disorders01:29

Bone Disorders

4.4K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Area of Science:

  • Gerontology
  • Cell Biology
  • Biochemistry

Background:

  • Aging is an irreversible process influenced by environmental and endogenous factors.
  • Cellular stress leads to oxidative stress, inflammation, and conventional cell death pathways (necrosis, apoptosis, autophagy).
  • Ferroptosis, a novel iron-dependent regulated cell death, is implicated in various diseases.

Purpose of the Study:

  • To review evidence supporting the role of ferroptosis in the aging process.
  • To highlight the implications of ferroptosis in age-related disorders (ARD).
  • To emphasize the need for interventions against excessive ferroptosis.

Main Methods:

  • Literature review of existing research on ferroptosis and aging.
  • Analysis of mechanisms linking oxidative stress, iron dysregulation, and cell death.
  • Synthesis of evidence for ferroptosis's contribution to aging phenotypes.

Main Results:

  • Ferroptosis involves dysregulated iron, leading to excessive lipid peroxidation and cell death.
  • Evidence suggests ferroptosis plays a role in cardiovascular, neurological, and other age-related diseases.
  • Imbalance in oxidation-antioxidant processes contributes to ferroptosis and accelerated aging.

Conclusions:

  • Ferroptosis is a significant mechanism potentially driving aging and age-related diseases.
  • Targeting ferroptosis may offer novel therapeutic strategies for combating aging.
  • Further research is needed to explore interventions to prevent excessive ferroptosis and mitigate aging liabilities.
