Proteomics01:33

Proteomics

9.8K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

What is Conservation Biology?

24.4K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Biological Effects of Radiation02:59

Biological Effects of Radiation

18.1K
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...

Synthetic Biology

5.6K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

650
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Biological Influences on Intelligence01:30

Biological Influences on Intelligence

568
Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...

Area of Science:

  • Marine biology
  • Proteomics
  • Molecular biology

Background:

  • Dinoflagellates cause harmful algal blooms (red tides), but bloom formation mechanisms are poorly understood.
  • Transcriptomic studies in dinoflagellates yield limited insights due to muted responses and poor mRNA-protein correlation.

Purpose of the Study:

  • To highlight the utility of high-throughput proteomics in dinoflagellate research.
  • To propose proteomics as a superior method for understanding dinoflagellate cell biology and environmental responses.

Main Methods:

  • Review of high-throughput proteomics techniques.
  • Comparison of proteomic and transcriptomic approaches for studying dinoflagellates.

Main Results:

  • Proteomics directly measures proteins, offering clearer insights into cellular function and phenotype changes.
  • Proteomics provides a valuable alternative to transcriptomics for eukaryotes with muted transcriptional responses.

Conclusions:

  • High-throughput proteomics is crucial for unraveling dinoflagellate mysteries, including harmful algal bloom initiation and coral symbiont acclimation.
  • Proteomic methods are applicable to a broad range of eukaryotic organisms exhibiting similar biological challenges.
