Genomics02:02

Genomics

40.9K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Classification of Elements and Compounds02:54

Classification of Elements and Compounds

73.9K
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond. Elements are classified as atomic or molecular based on the nature of their basic units.
Compounds are pure substances composed of two or more elements in fixed, definite proportions. Compounds are classified as ionic or molecular (covalent) based on the bonds...

Microtubules01:35

Microtubules

101.6K
There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.

CRISPR01:59

CRISPR

58.0K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

The Nucleolus02:55

The Nucleolus

10.5K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Area of Science:

  • * Glycomics and Parasitology
  • * Molecular Biology and Immunology

Background:

  • * Caenorhabditis elegans is a key model organism for studying development, immunity, and host-pathogen interactions.
  • * N-glycans in C. elegans share structural motifs with other nematodes, trematodes, and insects, suggesting conserved biological functions.
  • * Glycan-binding toxins interacting with C. elegans glycans also target agriculturally significant species, highlighting the need for comparative studies.

Purpose of the Study:

  • * To develop and characterize a comprehensive N-glycan shotgun array for Caenorhabditis elegans.
  • * To provide a platform for investigating conserved protein-carbohydrate interactions across diverse species.
  • * To facilitate research into host-pathogen interactions and the function of novel glycan structures.

Main Methods:

  • * Creation of a Caenorhabditis elegans N-glycan shotgun array comprising 134 distinct glycomers.
  • * Characterization of arrayed glycans using two-dimensional separation, ion trap mass spectrometry, and lectin affinity.
  • * Inclusion of diverse N-glycan subclasses: high mannose, pauci mannose, high fucose, mammalian-like complex, and phosphorylcholine substituted forms.

Main Results:

  • * The array successfully represents a broad spectrum of C. elegans N-glycans, including novel high fucose structures.
  • * Glycans on the array have been rigorously characterized, ensuring their structural integrity and suitability for binding studies.
  • * The array includes glycan motifs conserved across nematodes, trematodes, and insects, validating its cross-species applicability.

Conclusions:

  • * The developed C. elegans N-glycan array is a valuable tool for studying glycan-binding proteins.
  • * The array enables research into conserved protein-carbohydrate interactions in nematodes, trematodes, and insects.
  • * This platform can advance our understanding of host-pathogen interactions and glycan biology in various organisms.
