Summary
Primary cilia, essential cell organelles, are crucial for interpreting Sonic Hedgehog (Shh) signals during embryonic development. These structures play a key role in cellular communication and developmental processes.
Area of Science:
- Cell Biology
- Developmental Biology
- Biochemistry
Background:
- Cilia are microtubule-based organelles found on cell surfaces.
- Primary cilia are ubiquitous in vertebrate cells and involved in signal transduction.
- Sonic Hedgehog (Shh) signaling is critical in embryonic development.
Purpose of the Study:
- To summarize primary cilia structure and biogenesis.
- To review evidence linking cilia to signal transduction.
- To focus on the role and mechanism of cilia in Shh signaling within the embryonic neural tube.
Main Methods:
- Literature review of primary cilia structure and function.
- Analysis of evidence for cilia in signal transduction.
- Focus on molecular mechanisms of Shh pathway in cilia.
Main Results:

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

01:22Microtubules in Signaling
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
01:12Role 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...

03:14Notch 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 until 1985...
