Epigenetic Regulation01:37

Epigenetic Regulation

3.1K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

2.3K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

34.8K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Inflammatory Response01:28

Inflammatory Response

2.3K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.1K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Inheritance of Chromatin Structures03:17

Inheritance of Chromatin Structures

6.3K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Area of Science:

  • Surgical Innovation
  • Biomaterials Science
  • Molecular Biology

Background:

  • Inflammation is intrinsically linked to hernia development and occurrence.
  • Surgical repair of hernias often involves prosthetic meshes, which can elicit varying inflammatory responses.
  • Polypropylene meshes are the current standard, but efforts are ongoing to mitigate associated inflammation.

Purpose of the Study:

  • To review the multifaceted role of inflammation in hernias.
  • To discuss mesh-related inflammatory responses in hernia repair.
  • To explore the emerging role of microRNAs (miRNAs) in hernia pathogenesis and inflammation.

Main Methods:

  • Literature review of studies on hernia inflammation, surgical repair, mesh materials, and miRNAs.
  • Analysis of inflammatory cytokine profiles post-surgery.
  • Examination of epigenetic factors, specifically miRNAs, in hernia research.

Main Results:

  • Surgical procedures and hernia repair meshes significantly influence the inflammatory environment.
  • Different mesh materials induce distinct pro-inflammatory or anti-inflammatory responses.
  • Emerging evidence suggests microRNAs play a role in hernia-related inflammation, indicating epigenetic involvement.

Conclusions:

  • Understanding and modulating inflammation is crucial for optimizing hernia repair outcomes.
  • Further research into biomaterial modifications and miRNA-based therapies holds promise for improved hernia treatment.
  • This review synthesizes current knowledge on inflammation in hernias, from surgical techniques to molecular mechanisms.
