Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

10.0K
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...

Pharmacogenomics: Identification of New Drug Targets

73
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...

Satellite Stem Cells and Muscular Dystrophy

2.5K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Incomplete Dominance01:43

Incomplete Dominance

32.0K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Area of Science:

  • Neurogenetics
  • Molecular Biology
  • Disease Mechanisms

Background:

  • Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with no known cure.
  • Genetic factors play a significant role in ALS pathogenesis, with ongoing research identifying novel gene mutations.
  • Understanding the genetic landscape of ALS is crucial for developing targeted therapeutic strategies.

Purpose of the Study:

  • To summarize major genetic advances in amyotrophic lateral sclerosis (ALS) over the past two years.
  • To highlight newly identified genes associated with ALS.
  • To provide an update on C9orf72 research and its implications.

Main Methods:

  • Large exome screening studies to identify genetic variations.
  • Traditional linkage analysis and candidate gene screening.
  • Development of reagents for studying C9orf72 protein function.

Main Results:

  • Identification of significant variations in seven genes: TBK1, CCNF, GLE1, MATR3, TUBA4A, CHCHD10, and NEK1.
  • These genetic findings implicate diverse cellular processes including proteostasis, RNA export, and DNA repair.
  • Advancements in understanding the normal function of C9orf72 protein.

Conclusions:

  • Genetic heterogeneity in ALS is rapidly expanding, revealing new molecular pathways.
  • Integrative functional studies are necessary to connect identified genes with disease mechanisms.
  • A comprehensive understanding of ALS genetics is essential for advancing effective therapies.
