THE EFFECTS OF CATHODE RAYS ON THE PROTEINS OF SERUM
The Journal of Experimental Medicine
|October 30, 2009
Summary
Cathode rays denature serum proteins, altering fibroblast growth. These changes, including protein breakdown and ammonia formation, explain observed effects on fibroblast cultures in irradiated serum.
Area of Science:
- Biochemistry
- Cell Biology
- Radiation Biology
Background:
- Serum proteins influence fibroblast growth.
- Previous studies noted effects of irradiated serum on fibroblasts.
Purpose of the Study:
- To elucidate the specific effects of cathode rays on serum proteins.
- To correlate protein alterations with observed effects on fibroblast cultures.
Main Methods:
- Exposure of serum to cathode rays.
- Analysis of protein denaturation and hydrolysis products.
- Observation of fibroblast cultures grown in treated serum.
Main Results:
- Cathode rays cause significant protein denaturation and some hydrolysis.
- Formation of insoluble protein aggregates and ammonia.
- Irradiated serum promoted fibroblast growth and characteristic cellular changes.
Conclusions:
- Cathode ray irradiation induces specific biochemical changes in serum proteins.
- These protein alterations account for the observed stimulatory effects on fibroblast proliferation and morphology.
- The study links biophysical treatment to cellular responses via protein modification.

01:28Protein 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...
02:59Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
01:18Effects of EDTA on End-Point Detection Methods
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...

01:18Factors Affecting Protein-Drug Binding: Drug-Related Factors
Drug binding to proteins is a complex phenomenon influenced by various drug-related factors, each playing a significant role in the interaction between drugs and proteins within the body.
One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In contrast,...

01:20Protein Buffers in Blood Plasma and Cells
The human body utilizes protein buffer systems to maintain a stable pH. These systems capitalize on the dual role of amino acids, which can act as acids or bases by accepting or releasing hydrogen ions in response to pH changes. Protein buffer systems are particularly significant in the extracellular fluid (ECF) and intracellular fluid (ICF) of active cells, where structural and functional proteins provide substantial buffering capacity.

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
