Ligand Binding and Linkage00:49

Ligand Binding and Linkage

5.7K
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Genome-wide Association Studies-GWAS

15.9K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Evolutionary Relationships through Genome Comparisons

7.1K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Pharmacodynamic Models: Link Model and Systems Pharmacodynamic Model

50
The link model is a fundamental pharmacokinetic-pharmacodynamic (PK–PD) approach to account for delayed drug responses when the observed effect does not immediately correlate with the drug's plasma concentration peak. This delay is mathematically addressed by introducing an effect compartment concentration, Ce, which is kinetically linked to the plasma concentration, Cp, via a first-order rate constant, ke0. The linkage allows for a more accurate prediction of drug effects over time. A...

Area of Science:

  • Genetics
  • Neuroscience
  • Gerontology

Background:

  • Increasing evidence points to a partial genetic basis for neurodegenerative disorders.
  • Gene causality is established through familial segregation or population association studies.
  • Some genetic loci harbor variants linked to both rare Mendelian and common sporadic diseases.

Purpose of the Study:

  • To elucidate the genetic architecture of age-related neurodegenerative diseases, with a focus on Parkinson's disease.
  • To explore systematic approaches for inferring gene relationships within disease contexts.
  • To identify core biological pathways implicated in neurodegenerative pathogenesis.

Main Methods:

  • Review of genetic studies on neurodegenerative disorders.
  • Analysis of gene variants and their association with disease risk (segregation and association).
  • Systematic approaches to infer gene-disease relationships and identify common pathways.

Main Results:

  • Genetic variants play a significant role in the risk of neurodegenerative diseases.
  • Mendelian and sporadic disease forms can arise from variants at the same genetic loci.
  • Systematic analyses suggest a limited number of underlying biological pathways drive pathogenesis.

Conclusions:

  • A comprehensive understanding of the genetic architecture is crucial for neurodegenerative diseases.
  • Identifying shared biological pathways can offer insights into disease mechanisms and therapeutic strategies.
  • Further research into genetic factors is essential for combating age-related neurodegeneration.
