Gene Regulation During Sporulation01:17

Gene Regulation During Sporulation

532
Sporulation is a complex developmental process that allows certain Gram-positive bacteria, such as Bacillus subtilis and Clostridium species, to survive extreme environmental conditions. This process is tightly regulated by a series of signaling cascades and transcriptional controls, ensuring the formation of a highly resistant endospore.Sporulation is triggered by unfavorable conditions, such as nutrient depletion, and is governed by a phosphorelay system. One of the sensor kinases, such as...

Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.6K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Constitutive and Regulated Gene Expression

1.3K
Gene expression in prokaryotes is governed by constitutive and regulated systems, allowing cells to balance the production of essential proteins with adaptive responses to environmental changes.Constitutive Gene ExpressionConstitutive, or housekeeping, genes are continuously expressed as they encode proteins vital for fundamental cellular processes. These include enzymes for glycolysis, ribosomal components for protein synthesis, and proteins involved in DNA replication. Their constant...

Gene Regulation in Microbial Communities: Quorum Sensing

713
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Fixed Action Patterns01:06

Fixed Action Patterns

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

  • Bioinformatics
  • Computational Biology
  • Systems Biology

Background:

  • Gene regulation sequential pattern mining is crucial for disease study.
  • Existing methods overlook gene-disease association and gene expression levels.
  • This leads to discovery of numerous, often irrelevant, patterns.

Purpose of the Study:

  • To propose a utility model incorporating gene-disease association and expression levels.

Main Methods:

  • Developed a utility model considering gene-disease association scores and expression levels.
  • Proposed the Top-HUGS algorithm for pattern discovery in time-course microarray data.
  • Implemented a Java-based web interface for system usability.

Main Results:

  • Evaluated on a public time-course microarray dataset.
  • Achieved higher accuracy compared to baseline methods.
  • Identified novel gene regulation patterns providing biological insights.

Conclusions:

  • The Top-HUGS method effectively discovers significant high-utility gene regulation sequential patterns.
  • The approach offers valuable insights into disease mechanisms and biological processes.
  • This work represents the first demonstration of significant high-utility gene regulation sequential pattern discovery.
