Insights

Oligonucleotide gene therapy offers a less invasive approach to treating blinding neovascular eye diseases. Advancements in nucleotide chemistry and delivery systems enhance its efficacy in inhibiting angiogenesis and improving vision.

Area of Science:

  • Ophthalmology
  • Molecular Biology
  • Gene Therapy

Background:

  • Neovascularization of retinal tissue causes blinding eye diseases, a leading cause of vision loss.
  • Current treatments like laser photocoagulation have limited efficacy and can impair vision.
  • Angiogenesis, the formation of new blood vessels, is a key process in these diseases.

Purpose of the Study:

  • To explore oligonucleotide gene therapy as a novel, less invasive treatment for neovascular eye diseases.
  • To highlight advancements in nucleotide chemistry and delivery systems for improved therapeutic outcomes.
  • To investigate methods for inhibiting key metabolic processes in angiogenesis.

Main Methods:

  • Utilizing short stretches of nucleotides (oligonucleotides) as inhibitors of angiogenesis.
  • Developing improved nucleotide chemistries to enhance stability and longevity.
  • Advancing delivery systems for increased cellular penetration and targeted delivery.

Main Results:

  • Oligonucleotide gene therapy demonstrates potential in halting angiogenesis progression.
  • Enhanced nucleotide chemistries address issues like endonuclease activity, improving longevity.
  • Improved delivery systems increase cellular penetration and target specific cells/organs.

Conclusions:

  • Oligonucleotide gene therapy represents a promising therapeutic strategy for blinding neovascular eye diseases.
  • Combined advancements in chemistry and delivery significantly enhance treatment efficacy.
  • This approach offers a less invasive alternative with potential for vision preservation.

Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
