Mutation in the fibroblast growth factor receptor (FGFR) gene results in achondroplasia (dwarfism), which is a dominant condition caused by a single base substitution (GGG>AGG) that changes the amino acid glycine at position 480 to arginine (G480R) in the FGFR protein. FGFR is normally active when FGF binds to it, but the mutant FGFR is always on to stimulate signaling that inhibits excessive bone growth.
How can gene therapy be used to treat achondroplasia? Select all that apply.
RNAi that knocks down the mutant FGFR expression
Adeno-associated viral (AAV) vector that carries the wild-type FGFR
Retroviral vector that carries the wild-type FGFR
CRISPR with the wild-type FGFR donor DNA
Using molecular cloning, a hybrid receptoer is produced that consists of the extracellular domain of the B-adrenergic
receptor (B-AR) and the transmembrane and intracellular domains of the EGF receptor (EGFR).
Question:

- Troponin is a complex composed of Troponin C (TnC), Troponin I (TnI), and Troponin T (TnT); the complex is found in skeletal and cardiac muscle, but not smooth muscle. Two "isoforms" of TnI and two "isoforms" of TnT are expressed in human skeletal muscle tissue. Q:The isoforms of TnI in the sentence above mean: A:One single TnI gene encodes two different TnI proteins as a result of alternative splicing of the TnI pre-mRNA. B:There are two different TnI genes, each produces a TnI protein.arrow_forwardWhich of the following would you expect to happen if amino acids 579 to 582 (YIYV) in the PDGF-Beta receptor were exchanged with amino acids 992 to 995 (YLIP) from the EGF receptor to give PDGF (YLIP) and EGF (YIYV) (Select all that apply)?

Why or why not?arrow_forwardDraw a cell signaling pathway following EGFR activation in host cells with the possible downstream activities. The new covid-19 strain acts on other cells in the body such as the lungs and kidney via ACE2. (we will say that EGFR is a receptor for the new variant).arrow_forwardA snapshot of a portion of the SARS-CoV-2 spike protein bound to the human ACE2 receptor (taken from PDB) is shown below. The spike protein is in orange and the ACE2 receptor is in green. Within the red-circled region are 2 amino acids connected by a dashed line (added by Dr. David). These amino acids are a tyrosine residue from the spike protein and an aspartate residue from the ACE2 receptor. w cozedarrow_forward
- A -------| B-------> Violet A linear switch-regulation pathway of the type shown here controls flower color in a certain species. The wildtype color is violet, but mutants can be either white or purple. Gene products A and B act in the pathway at the positions and in the manner shown (A is inhibitory, B is intensifying). A and B are the products of genes A and B, respectively. What are the expected phenotypes of: (a) A loss-of-function mutation in A? (b) A gain-of-function mutation in A? (c) A loss-of-function mutation in B? (d) A gain-of-function mutation in B?arrow_forwardThe Wnt planar polarity signaling pathway nor-mally ensures that each wing cell in Drosophila has a sin-gle hair. Overexpression of the Frizzled gene from a heat-shock promoter (hs-Fz) causes multiple hairs to grow frommany cells (Figure Q15–5A). This phenotype is suppressedif hs-Fz is combined with a heterozygous deletion (DshΔ)of the Dishevelled gene (Figure Q15–5B). Do these resultsallow you to order the action of Frizzled and Dishevelledin the signaling pathway? If so, what is the order? Explainyour reasoningarrow_forwardIn an experimental motile fibroblast cell line, Nucleation Promoting Factor (NPF) was mutated in such a way that it no longer could bind to the G-actin monomers. Which of the following would you observe in these cells as a consequence of the mutation at the molecular level? None of the other is true. The cell will not be able to form branching of the actins using Arp2/3 complex at the leading edge and causing movement arrest The filamin protein will not be recruited for crosslinking the actins and will cause the arrest of movement. The Arp2/3 and filamin will not be able to dissociate from actin in the absence of NPF and the cells will be restricted to move in one direction onlyarrow_forward
- The gene Igf2 for the insulin-like growth factor (IGF) promotes growth hormone production and cell proliferation, and is maternally imprited. The IGF receptor gene Igf2r counters the effects of the Igf2 gene and is paternally imprinted.
