Question
Chapter 45, Problem 12TYU
Summary Introduction
To explain: How melanocyte-stimulating hormone (MSH) enables skin color change and distribution in frog based on its surrounding and how neuroendocrine signals activate MSH.
Concept introduction:
In neuroendocrine pathway, sensory neurons stimulate neurosecretory cells to release neurohormones. Like endocrine hormones, neurohormones reach their target receptors via the bloodstream. MSH is a peptide hormone produced by skin, pituitary and hypothalamus. It stimulates melanocytes to produce melanin pigment.

- A scientist observes a mutation in the transmembrane region of EGFR that eliminates its ability to be stabilized by binding interactions during dimerization after ligand binding. Which hypothesis regarding the effect of this mutation on EGF signaling is most likely to be correct? EGF signaling cascades would be active for longer in the cell. EGF signaling cascades would be active for a shorter period of time in the cell. EGF signaling cascades would not occur. EGF signaling would be unaffected.arrow_forwardWhat effect will a cAMP inhibitor have on a peptide hormone-mediated signaling pathway? It will prevent the hormone from binding its receptor It will prevent activation of a G-protein It will prevent activation of adenylate cyclase It will prevent activation of protein kinases.arrow_forwardDescribe three different responses of a cell-surfacereceptor on binding a signaling molecule and undergoing aconformational change.arrow_forward
- Concept test: Please discuss thoroughly. One of the key components in vertebrate limb development is the polarizing region, also known as the zone or polarizing activity of ZPA. Where in the limb bud is this region? What axis of the limb does it help to specify? What properties of this region make it an organizing region Through which signaling molecule does it exert its effects? What is the evidence for the importance of this molecule?arrow_forwardDescribe the mechanism of axon pathfinding. Include the parts, how they interact, and the consequences for signaling by netrin and slit, via the Rho family of small GTPases and the actin cytoskeletonarrow_forward1a) Create a diagram which illustrates the typical signaling mechanism of action G protein-coupled receptors and possible routes of communication (autocrine etc.). Should show the specific molecules involved, the mechanisms of signal transduction and indicate the different pathways that are activated.

- Briefly describe the effects of positive and negative feedback loops on signalling pathway responses. How do the two loops functionally differ when pathway input stimulus shifts from present to absent? Please keep brief - 4 sentences/dot points max.arrow_forwardE: Using either GPCRs (G-protein couples receptors) or RTKs (Receptor tyrosine kinases), describe: 1. How ligand binding activates the receptor. Ex: which proteins are involved? what changes can occur to the receptor after binding the ligand? 2. A signal transduction pathway that occurs due to the ligand binding (must include a secondary messenger). 3. Any cellular response due to the ligand binding. 4. A way that the signal pathway is regulated.arrow_forwardShown in this diagram, describe (and connect) 5 outcomes that could occur due to loss of FMRP function in this cell.
