Pharmacogenomics: Identification of New Drug Targets01:29

Pharmacogenomics: Identification of New Drug Targets

53
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...

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

65
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...

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters01:16

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters

79
The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...

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

56
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...

Gene Regulation in Microbial Communities: Quorum Sensing01:28

Gene Regulation in Microbial Communities: Quorum Sensing

779
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

18.8K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Area of Science:

  • Genetics
  • Periodontology
  • Immunology

Background:

  • Periodontitis, a common gum disease, is influenced by genetic and environmental factors.
  • Aggressive and chronic periodontitis may share genetic predispositions.
  • Understanding genetic variations is key to differentiating disease forms.

Purpose of the Study:

  • To investigate shared and unique genetic associations in aggressive and chronic periodontitis.
  • To identify specific gene polymorphisms linked to different periodontitis phenotypes.
  • To compare genetic profiles of patients with periodontitis to healthy controls.

Main Methods:

  • Genotyping of ten functional polymorphisms in seven candidate genes.
  • Recruitment of 51 aggressive periodontitis patients, 57 chronic periodontitis patients, and 100 healthy controls.
  • Statistical analysis of genotype frequencies between disease groups and controls.

Main Results:

  • Significant genotype frequency differences were observed between aggressive periodontitis and controls (IL-1B +3954, IL-6 -174).
  • Significant genotype frequency differences were found between chronic periodontitis and controls (IL-6 -174, VDR -1056).
  • Unique genetic associations were identified for chronic versus aggressive periodontitis (IL-1A -889), and shared associations for periodontitis overall (VDR -1056, TLR-4 399, IL-6 -174).

Conclusions:

  • The study supports the hypothesis of both shared and unique genetic associations in aggressive and chronic periodontitis.
  • Specific gene polymorphisms are implicated in the distinct and overlapping genetic underpinnings of these periodontitis forms.
  • Genetic analysis provides insights into the etiology and potential differentiation of periodontitis subtypes.
