Can you achieve telomere maintenance without using gene therapy

Click For Summary

Discussion Overview

The discussion revolves around the possibility of achieving telomere maintenance without the use of gene therapy. Participants explore various methods and delivery mechanisms for telomerase, including the feasibility of direct injection and alternative delivery systems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether injecting pure telomerase would be effective, noting concerns about its ability to enter cells.
  • Another participant mentions that adenoviruses are not ideal for telomerase delivery since their genes do not integrate into the host's DNA, which limits their effectiveness in dividing cells.
  • There is a suggestion that nanoparticles could potentially deliver telomerase, although concerns about size and delivery efficiency are raised.
  • Participants inquire about the use of a gene gun for gene therapy and whether it could be used to deliver telomerase, with skepticism expressed regarding the practicality of this method.
  • A biolistic particle delivery system is described, where DNA coated on heavy metal is delivered into cells, but doubts are raised about its effectiveness for telomerase delivery.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of various delivery methods for telomerase, indicating that multiple competing ideas remain without consensus on the best approach.

Contextual Notes

Limitations include uncertainties about the size of telomerase and the effectiveness of various delivery methods, as well as the implications of using different viral vectors.

Can you achieve telomere maintenance without using gene therapy?
if so, what are the ways?
thanks
 
Biology news on Phys.org
is it possible injecting pure telomerase would work or would it not be able to get inside the cells?
I thought adeno associated virus would be used if it were ever done? But would you not be able to use that on a large quantity of cells?
 
enzymes cannot get into the cell especially not the nucleus where your genes are. The reason adenovirus is unfavorable is precisely because you mentioned telomerase as in the gene will only be used when the cell divides. Adenoviruses' genes cannot be passed onto the daughter cells because their dna is never integrated into the host unlike retroviruses that do integrate their genes into the host.
 
can telomerase be delivered by nanoparticles or anything or is it still to big, for the cell to be able to get additional telomerase without gene therapy?

example of nanoparticle protein delivery:

also can a gene gun be used to do gene therapy on a person? why or why not?
 
can a gene gun be used to deliver telomerase? its a large protein
 
Biolistic particle delivery system? You coat a heavy metal (usually gold) with DNA, which is then shot through tissues. While the heavy metal passes through the cells the DNA gets stripped and stays behind in the cells. No, for obvious reasons.
