Describe the signalling pathways that are active at the 4 cell stage of development in C. elegans.
Homework Answers
Signalling pathways are the key biological mechanism that transdue extracellular signals to affect transcription factor mediated gene regulations within cells a number of computational methods have been developed to identify the topological structure of a specific signaling pathway using protein-protien interaction data, but they are not design for identify active signalling pathway in an unbaised manner on the other hand, there are statistics methods based on gene sets for pathway data that can prioritize likely active signalling pathway, but they do not make full use of active pathway structure that link receptor, kinases and downstream transcription factor

Hello. I need help answering this question that focuses on cell signalling pathways and insulin signalling pathways: 3) What is the relationship between type 2 diabetes and insulin production? How is it that a drug that increases insulin sensitivity might help treating this disease?

Choose one out of paracrine signalling, endocrine signalling, autocrine signalling and direct signalling and describe briefly the process by which this occurs. Pick a representative signal molecule from the pathway you have chosen and indicate its function, the type of cell in which it is made and the specific manner in which it acts as a signalling molecule, including the receptor that it binds to. For example if you chose the endocrine signalling pathway you could consider looking at a...

Induction is a major theme in developmental biology as these cell-cell signalling events are essential in coordinating development within the body plan. Induction, for example, allows for simple embryonic structures to give rise to a diversity of structures in adults (e.g., somite) or, allows for different germ layers to collectively give rise to a complex organ (e.g., limb, eye). What is induction (3 pts)? Using specific examples, describe the role of induction in coordinating development (4 pts) and also in...

Lymphocyte Development 1. B cell development in the bone marrow shares may features with T cell development in the thymus. A) Discuss what you consider to be the two major goals of lymphocyte development (i.e, what is the purpose of the Bone marrow and Thymus environments). B) Describe what occurs during the Precursor B cell stage and identify/describe the analogous stage in T cells.

5.DISEASE AND PATHWAYS: Most drugs target proteins involved in signaling pathways in the cell. Describe two examples by which a protein can be chemically altered and thereby act as a logic switch in a signaling pathway in the cell. 6.MOLECULAR DRUG DOCKING: Why is molecular docking (e.g. autodock vina) take less time to run than molecular dynamics? What aspect of molecular reality regarding the target protein is sacrificed during simulation to obtain computational speed?
