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...

Aging

Aging

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...

Somatic to iPS Cell Reprogramming

Somatic to iPS Cell Reprogramming

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012 for this...

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Introduction to Nuclear Reprogramming

Introduction to Nuclear Reprogramming

Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

Methods of Nuclear Reprogramming

Methods of Nuclear Reprogramming

Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for injury repair.

Summary

Fetal distress, including DNA damage during embryonic development, may accelerate aging. This study suggests early-life DNA damage, not just cumulative damage, can impact lifespan and premature aging.

Area of Science:

Genetics and Epigenetics
Developmental Biology
Aging Research

Background:

Aging is characterized by progressive degeneration, often attributed to accumulated DNA damage limiting tissue regeneration.
Intrauterine programming suggests fetal exposures can impact adult disease, but the role of fetal DNA damage on lifespan is unclear.

Purpose of the Study:

To investigate the impact of intrauterine DNA damage on premature aging.
To explore the link between fetal distress and compromised regenerative capacity.

Main Methods:

Generation of a murine model for a human syndrome with defective DNA repair.
Observation of premature aging phenotypes in the model.
Analysis of DNA damage accumulation, particularly during the embryonic period.

Published on: October 25, 2015

Main Results:

Mice with defective DNA repair exhibited premature aging.
DNA damage accumulation was predominantly observed during the embryonic stage.
This suggests a critical window for DNA damage's impact on aging.

Conclusions:

Fetal distress, specifically DNA damage during embryonic development, can significantly influence aging.
Early-life DNA damage accumulation may be a key driver of premature aging, independent of later-life damage.
Findings challenge traditional models of aging by highlighting the role of intrauterine programming.
