Summary
The Hippo pathway regulates organ growth and cell differentiation. Cell junctions and the microenvironment control this pathway, and its dysregulation is linked to cancer development.
Area of Science:
- Cell Biology
- Developmental Biology
- Cancer Biology
Background:
- The Hippo pathway is a critical regulator of organ size and cell fate.
- Its activity is influenced by cell-cell junctions, cellular structure, and mechanical cues.
- Aberrant Hippo signaling is implicated in various cancers.
Purpose of the Study:
- To review recent advances in understanding how cell junctions and the microenvironment regulate the Hippo pathway.
- To explore the role of these mechanisms in organ development and regeneration.
- To discuss the implications of Hippo pathway dysregulation in cancer.
Main Methods:
- Literature review of recent research on the Hippo pathway.
- Analysis of signaling mechanisms involving cell junctions and the microenvironment.
- Synthesis of findings related to development, regeneration, and cancer.
Main Results:
- Cell junctions act as crucial sensors of the microenvironment, transducing signals that modulate Hippo pathway activity.
- Mechanical properties of the cellular environment play a significant role in controlling Hippo pathway signaling.
- Defects in these sensing mechanisms can lead to uncontrolled cell proliferation and cancer.
Conclusions:
- Cell junctions and microenvironmental cues are integral to Hippo pathway regulation.
- Understanding these interactions is key to comprehending organ growth and cancer development.
- Targeting these pathways may offer therapeutic strategies for cancer treatment.

02:33Hedgehog Signaling Pathway
10.3K
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...

01:19Contact-dependent Signaling
48.2K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

10.0K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

01:29Tight Junctions
7.9K
Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in multicellular organisms. They are mainly composed of claudin and occludin transmembrane proteins, and other proteins such as tricellulin and JAM (junctional adhesion molecule). All these proteins are 4-pass transmembrane proteins, except JAM, which is a single-pass transmembrane protein belonging to the immunoglobulin superfamily. The...

01:14Overview of Cell-Cell Junctions
30.9K
The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and the extracellular matrix. Cell-cell junctions are specialized structures where the multi-protein complexes on one cell interact with the multi-protein complexes on another cell. These cell junctions are classified into three main types based on their function — occluding, anchoring, and gap junctions.
