Summary
MicroRNAs regulate primary cilium length. miR-669a-5p promotes cilium elongation by targeting G3BP, HDAC6, and AKAP12, offering new therapeutic targets for ciliopathies.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- Primary cilia are crucial cellular antennae for signal sensing, requiring precise length regulation for function.
- Dysregulated microRNA (miRNA) expression is linked to ciliopathies, but their role in cilium length control is unclear.
Purpose of the Study:
- To identify miRNAs that modulate primary cilium length.
- To elucidate the molecular mechanisms by which miRNAs regulate cilium length.
Main Methods:
- Calcium-shock method to induce cilia elongation.
- Small RNA sequencing to identify differentially expressed miRNAs.
- Cell culture experiments to validate miRNA function and target genes.
Main Results:
- miR-669a-5p was identified as a key miRNA promoting cilium elongation.
- miR-669a-5p represses G3BP, leading to reduced HDAC6 and increased AKAP12 expression.
- This pathway inhibits cilia disassembly, resulting in longer cilia.
Conclusions:
- A novel signaling pathway involving miR-669a-5p, G3BP, HDAC6, and AKAP12 regulates primary cilium length.
- This pathway represents a potential therapeutic target for treating ciliopathies.

01:22Microtubules in Signaling
1.7K
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...

01:05Mechanism of Ciliary Motion
3.7K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

3.3K
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...

01:39Mechanism of Filopodia Formation
2.3K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

00:50Anaphase Promoting Complex
2.9K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

01:32Cytoskeletal Coordination in Cell Migration
4.8K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...
