Summary
Wnt signalling is crucial for gastrointestinal stem cell functions like self-renewal and differentiation. Dysregulation of this pathway can lead to cancer development.
Area of Science:
- Cell Biology
- Developmental Biology
- Cancer Biology
Background:
- Wnt signalling regulates fundamental cellular processes such as proliferation, differentiation, apoptosis, and migration.
- Stem cells possess self-renewal and differentiation capabilities, vital for tissue homeostasis, particularly in the gastrointestinal tract.
Purpose of the Study:
- To review recent advancements in understanding Wnt signalling's role in gastrointestinal stem cell regulation.
- To explore how aberrant Wnt signalling contributes to cellular transformation and gastrointestinal cancer.
Main Methods:
- Literature review of current research on Wnt signalling and gastrointestinal stem cells.
- Analysis of studies linking Wnt pathway dysregulation to cancer pathogenesis.
Main Results:
- Wnt signalling is essential for maintaining the self-renewal and differentiation of gastrointestinal stem cells.
- Aberrant Wnt signalling can disrupt normal stem cell function, promoting uncontrolled proliferation and tumorigenesis.
Conclusions:
- A comprehensive understanding of Wnt signalling in gastrointestinal stem cells is key to developing targeted cancer therapies.
- Further research into the Wnt pathway's role in cancer is warranted.

02:54Canonical Wnt Signaling Pathway
10.7K
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

01:41Non-Canonical Wnt Signaling Pathways
8.5K
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

02:03What is Cell Signaling?
131.1K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.5K
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...

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.7K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

01:33Adult Stem Cells
33.9K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...
