Pharmacogenomics: Identification of New Drug Targets

76
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Gene Therapy

28.1K
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...

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

109
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Targeted Cancer Therapies

9.1K
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...

Area of Science:

  • Biotechnology
  • Genetics
  • Pharmacology

Background:

  • Orphan drugs are crucial for rare genetic diseases, attracting significant research investment.
  • Traditional pharmaceuticals are being explored as alternatives to biopharmaceuticals for single-gene disorder treatments.

Purpose of the Study:

  • To review the potential of traditional pharmaceuticals for treating single-gene disorders.
  • To survey current strategies and their applications in rare genetic diseases.

Main Methods:

  • Review of existing literature on pharmaceutical strategies for genetic diseases.
  • Analysis of antisense oligonucleotides (ASOs), siRNAs, and nonsense mutation read-through drugs.
  • Examination of approved drugs and clinical trial progress.

Main Results:

  • ASOs and siRNAs are used to knock down gene expression (e.g., APOB, transthyretin).
  • ASOs are in clinical trials for altering gene splicing (spinal muscular atrophy) and gene activation (Angelman syndrome).
  • Approved drugs exist for specific genetic conditions like familial hypercholesterolemia.

Conclusions:

  • Traditional pharmaceuticals show significant potential for treating single-gene disorders.
  • Advancements in ASOs and siRNAs offer new therapeutic avenues.
  • Future research may convert biopharmaceutical techniques like CRISPR-Cas9 into synthetic pharmaceutical approaches.
