NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

10.1K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Co-activators and Co-repressors

8.7K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Yeast Signaling01:28

Yeast Signaling

17.5K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

Transcriptional Regulation: Riboswitches01:23

Transcriptional Regulation: Riboswitches

809
Riboswitches are RNA elements that regulate gene expression by altering their secondary structures in response to specific effector molecules. These elements, located in the leader regions of certain mRNAs, act as transcriptional regulators by toggling between alternative conformations to control downstream gene expression. Riboswitch-mediated regulation is a precise mechanism for modulating biosynthetic pathways, as exemplified by the riboflavin biosynthesis pathway in Bacillus...

Gene Regulation During Sporulation01:17

Gene Regulation During Sporulation

535
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...

Prokaryotic Transcriptional Activators and Repressors01:58

Prokaryotic Transcriptional Activators and Repressors

25.7K
The organization of prokaryotic genes in their genome is notably different from that of eukaryotes. Prokaryotic genes are organized, such that the genes for proteins involved in the same biochemical process or function are located together in groups. This group of genes, along with their regulatory elements, are collectively known as an operon. The functional genes in an operon are transcribed together to give a single strand of mRNA known as polycistronic mRNA.

Summary
This summary is machine-generated.

Researchers studied the human Nuclear Factor kappa B (NF-κB) pathway in yeast, which lacks this pathway. This allowed for isolated analysis and the development of a predictive model for the NF-κB signaling network.

  • Reconstituted the human NF-κB pathway within the yeast system.
  • Developed a computational model to predict pathway dynamics.

Main Results:

  • Successfully established a functional human NF-κB pathway in an isolated cellular environment.
  • The developed predictive model accurately represented the behavior of the human NF-κB pathway.
  • Demonstrated the feasibility of using yeast to study complex human signaling pathways.

Conclusions:

  • Yeast provides a viable platform for studying human signaling pathways devoid of native interference.
  • The study successfully modeled the human NF-κB pathway, offering insights into its regulatory mechanisms.
  • This approach facilitates the development of predictive models for complex biological networks.
