Pharmacogenomics: Identification of New Drug Targets

119
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...

Inflammatory Bowel Disease III: Crohn's Disease

29
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

81
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Cystic Fibrosis: Pathogenesis

1.1K
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

1.1K
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Area of Science:

  • Genetics
  • Immunology
  • Gastroenterology

Background:

  • Celiac disease (CD) is a complex autoimmune disorder.
  • Significant progress has been made in understanding the genetic underpinnings of CD.
  • Beyond the established HLA association, numerous other genetic loci are implicated.

Purpose of the Study:

  • To review the current understanding of the genetic basis of celiac disease.
  • To highlight the role of immune system dysregulation in CD predisposition.
  • To discuss future directions for translating genetic discoveries into clinical applications.

Main Methods:

  • Review of recent genetic association studies in celiac disease.
  • Analysis of pleiotropic effects of identified genetic loci across autoimmune diseases.
  • Synthesis of current knowledge on genetic predisposition to CD.

Main Results:

  • Identification of 40 genomic loci associated with celiac disease, in addition to HLA.
  • Observation that many associated loci exhibit pleiotropic effects in other autoimmune diseases.
  • Emphasis on the central role of immune system dysregulation in CD pathogenesis.

Conclusions:

  • Genetic discoveries are rapidly advancing the understanding of celiac disease.
  • Current genetic data is insufficient for predicting individual clinical risk.
  • Translating genetic findings into improved disease mechanisms, treatments, and prevention for CD is a key future challenge.
