Gene Regulatory Circuits

A BCB420 Special Project


 


This project concerns the application of various information sources to define gene-regulatory circuits in molecular systems.



 




 


Context

 

The definition of molecular systems needs to take their functional components into account, as well as the components that create, assemble and disassemble these functional components. Among the latter, gene regulatory circuits play a particularly important role since they control when a particular system is constituted and becomes active. We can distinguish constitutive circuits (almost always on), developmental circuits (on only in certain cell-types), and regulated circuits (on in response to specific environmental signals or in ordered sequence of events such as the cell cycle).

In a previous set of BCH441 projects, students have curated biological systems, essentially based on Gene Ontology Annotations. In this special project the task is to define the gene regulatory circuits that operate on a select set of those systems, using three different information resources.


 

Task

 

You will work with the following two student annotated systems:

Task:

  • Access the two project pages and familiarize yourself with the contents.
  • Add a section "Gene regulation" to both pages


  • Evaluate the following three resources to identify transcription factors which target the genes that were annotated to this system and write your results into the respective two project pages:


  • For each of the three resources define:
    • which transcription factors are annotated to each gene (note: write a script to process downloaded data)
    • which of those transcription factors are enriched for the system



 

Deliverables

 
Annotations
Submit your annotations on the respective two project pages on the Student Wiki.
Scripts
Submit all scripts on a subpage of your User page on the Student Wiki;
Report
Write a brief final report about your experiences, your progress, and your results.
Journal
Document your activities in your Course Journal.
Progress
Each Tuesday before noon, email me a brief progress update.


 

The last day to submit material is Tuesday, April 3. at midnight. No extension will be possible.


 

Evaluation

 

The entire project will be worth 80 marks.

  • Your Scripts (R or python) will be worth 10 marks, they will be evaluated according to my Code marking rubrics.


 

Note: since no extension will be possible for this project, material that is submitted past the due date cannot be considered. Please get started right away, and aim to finish well before the deadline.
