Summary
A novel long non-coding RNA, lnc-Evf2, promotes osteogenic differentiation and bone formation. This discovery offers a potential new clinical target for ligament ossification and osteoporosis.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- Ossification of ligaments (OL) and osteoporosis (OP) are complex disorders lacking clear clinical biomarkers.
- Long non-coding RNAs (lncRNAs) play a role in disease pathogenesis.
Purpose of the Study:
- To identify and characterize the role of lnc-Evf2 in osteogenesis.
- To investigate the potential of lnc-Evf2 as a clinical target for OL and OP.
Main Methods:
- Identification of lnc-Evf2 in preosteoblasts.
- Analysis of lnc-Evf2 expression in ossified ligamentum flavum (OLF) and OP.
- Assessment of lnc-Evf2's role in osteogenic induction and mineralization.
- Knockdown experiments to evaluate the impact of lnc-Evf2 on osteogenic markers and Notch signaling pathway.
Main Results:
- lnc-Evf2 was overexpressed in OLF and underexpressed in OP.
- lnc-Evf2 expression increased during osteogenic induction, correlating with osteogenic markers and mineralization.
- lnc-Evf2 knockdown inhibited osteogenic differentiation and mineralization.
- Silencing lnc-Evf2 reduced protein levels of Notch2, Notch3, and Hes1, key regulators of osteogenesis.
Conclusions:
- lnc-Evf2 promotes osteogenic differentiation and bone formation via the Notch signaling pathway.
- lnc-Evf2 represents a potential novel clinical target for treating OL and OP.

03:14Notch Signaling Pathway
5.6K
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...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.3K
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.

01:16TGF - β Signaling Pathway
9.5K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

01:31Osteoclasts in Bone Remodeling
3.6K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

8.8K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

01:24Bone Formation by Endochondral Ossification
7.3K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
