Mitochondria

Mitochondria

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,...

Replicative Cell Senescence

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...

Multipotency of Hematopoietic Stem Cells

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Tissue Renewal without Stem Cells

Tissue Renewal without Stem Cells

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

The Effect of Aging on Tissues

The Effect of Aging on Tissues

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...

Mitochondrial Biology
Stem Cell Biology

Background:

Sirtuin 1 (a protein deacetylase) is crucial for regulating metabolism and gene silencing.
Information on sirtuins in stem cell biology is limited.
Sirtuin 1 plays a role in aging and metabolism across various species and tissues.

Purpose of the Study:

To review recent information on sirtuin 1.
To explore the role of sirtuin 1 in aging and metabolism.
To anticipate the influence of sirtuin 1 on stem cell aging.

Main Methods:

Review of recent scientific literature on sirtuin 1, aging, metabolism, and stem cells.
Analysis of the regulatory pathways involving sirtuin 1, peroxisome proliferator-activated receptor gamma-coactivator-1alpha, and mitochondrial biogenesis.
Examination of the impact of calorie restriction on lifespan and sirtuin 1 expression.

Main Results:

Calorie restriction extends lifespan by reorganizing mitochondrial metabolism via sirtuin 1, reducing oxidative damage.
Sirtuin 1 influences stem cell maintenance and growth factor responses.
Sirtuin 1 is essential for calorie restriction-induced lifespan extension and affects stem cell fate decisions through redox status.

Conclusions:
