Insights

Oxidative stress damages proteins, leading to harmful metabolic changes. The natural compound carnosine, a hydrophilic antioxidant, effectively protects proteins and extends lifespan, acting as a potent geroprotector.

Area of Science:

  • Biochemistry
  • Gerontology
  • Oxidative Stress Research

Background:

  • Oxidative stress causes dangerous protein damage, leading to loss of function and accumulation of difficult-to-remove glycated proteins.
  • Hydrophobic antioxidants show limited efficacy in preventing protein oxidative modification.

Purpose of the Study:

  • To investigate the protective effects of the natural hydrophilic antioxidant carnosine against protein oxidative damage.
  • To evaluate carnosine's potential as an anti-glycating agent and geroprotector.

Main Methods:

  • Assessment of carnosine's efficacy in preventing oxidative modification of proteins.
  • Evaluation of carnosine's impact on the lifespan of experimental animals under stress conditions.

Main Results:

  • Carnosine efficiently prevents oxidative modification of proteins.
  • Carnosine administration increased the lifespan of experimental animals exposed to unfavorable conditions.
  • Carnosine demonstrated potent anti-glycating properties.

Conclusions:

  • Carnosine is a highly effective natural hydrophilic antioxidant and anti-glycating agent.
  • Carnosine shows significant geroprotective properties, enhancing lifespan and protecting against oxidative damage.
  • Further research into carnosine's therapeutic potential is warranted.

Protein Modifications in the RER01:26

Protein Modifications in the RER

Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal sequences.
Protein Denaturation01:28

Protein Denaturation

The function of proteins depends on their native three-dimensional structure, which is dictated by the amino acid sequence of the specific protein. Folding of the polypeptide chain takes place under specific conditions that energetically favor the folded conformation. In contrast, protein denaturation occurs spontaneously under unfavorable conditions that disrupt the integrity of the folded conformation. Thus, the chemical and physical environment of a protein, such as significant changes in pH...
The Unfolded Protein Response01:37

The Unfolded Protein Response

The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...
Protein Folding01:25

Protein Folding

Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...
Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
Molecular Chaperones and Protein Folding03:00

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.
The...
