Abstract

Insights

The cylindromatosis (CYLD) tumor suppressor is crucial for zebrafish development, with its gene deletion causing early embryonic death. CYLD expression is vital for central nervous system development in zebrafish.

Area of Science:

  • Developmental Biology
  • Genetics
  • Molecular Biology

Background:

  • The cylindromatosis (CYLD) tumor suppressor is a microtubule-associated deubiquitinase involved in cell signaling.
  • CYLD's role in zebrafish development and physiology is not well understood.
  • This study investigates CYLD function in zebrafish using gene deletion.

Purpose of the Study:

  • To investigate the function of CYLD in zebrafish embryonic development.
  • To characterize the expression pattern of CYLD during zebrafish embryogenesis.
  • To determine the consequences of CYLD loss-of-function in zebrafish.

Main Methods:

  • Semi-quantitative RT-PCR to analyze CYLD mRNA expression levels.
  • Whole-mount in situ hybridization to visualize CYLD mRNA distribution.
  • TALEN-based gene deletion to create CYLD knockout zebrafish.

Main Results:

  • CYLD mRNA expression varied during early zebrafish embryonic development.
  • CYLD mRNA was localized to the brain and notochord.
  • Homozygous CYLD deletion led to embryonic lethality before 8 hours post-fertilization.

Conclusions:

  • CYLD plays a significant role in zebrafish central nervous system development.
  • Early embryonic lethality in CYLD mutants limits comprehensive analysis.
  • Further research is needed to fully elucidate CYLD's function in neurodevelopment.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...
