Summary
Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) mediate cell-specific communication. These non-coding RNAs interact, influencing cell identity and responses, similar to traditional ligand-receptor signaling.
Area of Science:
- Molecular Biology
- Cell Biology
- Genetics
Background:
- Intercellular communication is vital for development and disease, traditionally mediated by ligand-receptor interactions.
- Non-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), are emerging as key signaling molecules.
- lncRNAs exhibit diverse structures and functions, including acting as miRNA sponges and regulating gene expression.
Purpose of the Study:
- To propose a novel mechanism of cell-type-specific intercellular communication mediated by lncRNA-miRNA interactions.
- To highlight the analogy between lncRNA-miRNA interactions and classical receptor-ligand signaling pathways.
Main Methods:
- Review and synthesis of existing literature on ncRNA function and intercellular communication.
- Conceptual framework development proposing lncRNA-miRNA interactions as a driver of cell-specific signaling.
Main Results:
- lncRNAs can bind to miRNAs, modulating their availability to target mRNAs.
- Cell-type-specific expression of lncRNAs suggests a role in cell-specific signaling.
- lncRNA-miRNA interactions can initiate cell-type-specific signaling cascades and feedback loops.
Conclusions:
- lncRNA-miRNA interactions represent a significant mode of cell-type-specific communication.
- This interaction mechanism is crucial for determining cell identity and response to stimuli.
- Further research into lncRNA-miRNA networks can reveal new therapeutic targets for diseases like cancer.

02:03What is Cell Signaling?
129.9K
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.

01:19Interactions Between Signaling Pathways
7.3K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

03:14Notch Signaling Pathway
6.5K
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...

02:33Hedgehog Signaling Pathway
9.9K
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...

01:03Communication
8.7K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

01:28Insulin: The Receptor and Signaling Pathways
2.9K
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...
