Summary
Long non-coding RNAs (lncRNAs) are key regulators in cancer metastasis. These molecules interact with epithelial-mesenchymal transition (EMT) master regulators, offering new diagnostic and therapeutic strategies.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Cancer metastasis involves tumor cell dissemination and colonization.
- Epithelial-mesenchymal transition (EMT) is crucial for the invasion-metastasis cascade.
- Master regulators like TGF-β, Snail, ZEB, and Twist orchestrate EMT.
Purpose of the Study:
- Investigate the role of long non-coding RNAs (lncRNAs) in cancer metastasis.
- Elucidate the mechanisms by which lncRNAs regulate EMT.
- Explore lncRNAs as potential diagnostic and therapeutic targets.
Main Methods:
- Analysis of differentially expressed transcripts in primary versus metastatic cancers.
- Review of existing literature on lncRNA involvement in EMT.
- Focus on lncRNAs such as MALAT1, HOTAIR, H19, LncRNA-ATB, and LincRNA-ROR.
Main Results:
- lncRNAs are significantly dysregulated in metastatic cancers.
- Specific lncRNAs (e.g., MALAT1, HOTAIR) are implicated in promoting EMT.
- lncRNAs interact with EMT master regulators, influencing cancer progression.
Conclusions:
- lncRNAs play a critical role in regulating the EMT process during cancer metastasis.
- Understanding lncRNA-EMT interactions provides insights into cancer progression.
- Targeting lncRNAs offers novel avenues for cancer diagnosis, prognosis, and therapy.

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

03:18Non-LTR Retrotransposons
13.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

01:13Formation of Muscle Fibers from Myoblasts
6.1K
De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription...

01:19Cadherins in Tissue Organization
4.3K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
