Microtubule Associated Proteins (MAPs)01:42

Microtubule Associated Proteins (MAPs)

5.9K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

Gene Flow02:39

Gene Flow

38.0K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Gene Families01:57

Gene Families

10.0K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Gene Therapy00:59

Gene Therapy

27.7K
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...

Gene Conversion02:08

Gene Conversion

10.7K
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

What is Gene Expression?01:42

What is Gene Expression?

196.9K
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

Area of Science:

  • Pharmacogenetics
  • Chronobiology
  • Systems Biology

Background:

  • Genome-wide association studies (GWAS) identify genes for drug response variation.
  • Integrating pharmacokinetic (PK) and pharmacodynamic (PD) processes offers deeper insights into gene-drug relationships.
  • Existing methods do not fully capture the influence of biological timing on drug response.

Purpose of the Study:

  • To introduce a novel evolutionary framework, heterochronopharmacodynamics (HCPD).
  • To integrate chronopharmacodynamics and heterochrony for a comprehensive understanding of pharmacogenetic architecture.
  • To elucidate how genetic variations influence drug efficacy and toxicity in relation to circadian rhythms and drug concentrations.

Main Methods:

  • Development of an evolutionary framework combining chronopharmacodynamics and heterochrony.
  • Conceptual integration of developmental timing and circadian rhythms into pharmacogenetic analysis.
  • Application of the HCPD concept to interpret gene-drug interactions.

Main Results:

  • The proposed heterochronopharmacodynamics (HCPD) framework offers a new perspective on pharmacogenetics.
  • HCPD enhances the interpretation of how genetic variations impact drug efficacy and toxicity.
  • This approach better accounts for the influence of circadian rhythms and developmental timing on drug response.

Conclusions:

  • Heterochronopharmacodynamics (HCPD) provides a more complete understanding of the genetic basis of drug response.
  • Incorporating temporal dynamics (circadian and developmental) is crucial for precision medicine.
  • HCPD can guide future research in personalized drug therapy and toxicity prediction.
