Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.1K
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...

Regulation of Expression Occurs at Multiple Steps

23.0K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Regulation of Expression at Multiple Steps

968
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Combinatorial Gene Control02:33

Combinatorial Gene Control

8.4K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

23.4K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences  access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area. 
Topologically Associated Domains (TADs)
The 3-dimensional positioning of chromatin in the nucleus influences the...

Reporter Genes02:11

Reporter Genes

11.7K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

  • Synthetic Biology

Background:

  • Spatiotemporal pattern formation is crucial for biological processes like embryogenesis and neural development.

  • Coupled network dynamics with molecular diffusion in 1D and 2D space.
  • Analyzed parameter regimes for stability (monostable, multistable, oscillatory) and diffusion coefficients.

Main Results:

  • Demonstrated pattern formation from coupled network motifs and diffusion.
  • Observed influence of network stability and diffusion rates on pattern characteristics.
  • Identified specific network motifs capable of generating spatial patterns.

  • Synthetic gene networks coupled with diffusion can generate complex spatiotemporal patterns.
  • Network motif properties and diffusion dynamics are key determinants of pattern formation.
  • This modeling approach provides insights into biological pattern formation mechanisms.
