Pharmacogenomics: Identification of New Drug Targets

95
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...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

10.2K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Genome-wide Association Studies-GWAS

17.1K
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...

Genetic Screens02:46

Genetic Screens

5.9K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Data Collection II

10.5K
The nursing history captures and records the patient's health status, so that a care plan evolves to meet the patient's individual needs. The nursing health history is a part of the initial assessment. A comprehensive history covers all health dimensions and plays a significant role in the assessment process. A comprehensive history includes the patient's biographical information, reasons for seeking health care, expectations, present and past health history, medications, and...

Behavioral Genetics and Its Designs

1.4K
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Summary

Training lay individuals to build cancer family pedigrees improved their knowledge and communication about cancer risk. This intervention enhances familial cancer identification and awareness.

Area of Science:

  • Genetics
  • Public Health
  • Cancer Research

Background:

  • Family history is crucial for assessing cancer risk.
  • Effective communication and collection of family history data are vital for identifying familial cancer.
  • Current methods for collecting family history can be improved.

Purpose of the Study:

  • To enhance cancer family history communication and collection through lay individual training.
  • To improve the identification of familial cancer by empowering individuals to construct pedigrees.
  • To assess the impact of a pedigree construction intervention on participants' attitudes, knowledge, and behaviors.

Main Methods:

  • A study involving 200 participants who received an intervention on basic pedigree construction and interpretation for familial cancer.
  • Preintervention, postintervention, and 1-week follow-up surveys were used to assess pedigree construction skills and attitudes.
  • Data analysis focused on changes in participants' understanding, confidence, and reported actions regarding family cancer history.

Main Results:

  • Intervention participants showed more positive attitudes towards collecting family history.
  • Trained individuals demonstrated improved understanding of sample pedigrees and constructed more detailed family histories.
  • Postintervention, participants were more likely to intend to discuss cancer risk with family and physicians; 25% spoke with family by follow-up.

Conclusions:

  • The intervention effectively improved the communication and collection of cancer family history through pedigree construction.
  • Enhanced pedigree knowledge correlated with increased intentions to discuss cancer risk, particularly for those not yet having spoken with family.
  • This approach holds potential for improving the identification of individuals with familial cancers and raising awareness of hereditary cancer risk.
