Summary
Epithelial-mesenchymal transition (EMT) drives cancer metastasis. MicroRNAs (miRNAs) regulate EMT-related genes, influencing tumor spread by targeting key transcription factors involved in this critical process.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cancer metastasis involves complex genetic and molecular events.
- Epithelial-mesenchymal transition (EMT) is a crucial mechanism in tumor cell dissemination.
- The precise molecular mechanisms governing EMT in cancer remain incompletely understood.
Purpose of the Study:
- To review the intricate relationship between EMT and tumor metastasis.
- To explore the transcription factors central to EMT regulation.
- To elucidate the role of microRNAs (miRNAs) in modulating EMT-related transcription factors and subsequent cancer metastasis.
Main Methods:
- Literature review focusing on EMT, transcription factors, and miRNAs in cancer metastasis.
- Analysis of post-transcriptional gene regulation by miRNAs.
- Synthesis of current research on molecular mechanisms of metastasis.
Main Results:
- EMT is a key determinant of a tumor's ability to metastasize.
- Specific transcription factors are critical regulators of the EMT process.
- MicroRNAs significantly impact cancer metastasis by targeting EMT-related transcription factors.
Conclusions:
- Understanding the interplay between EMT, transcription factors, and miRNAs is vital for deciphering cancer metastasis.
- miRNAs represent a potential therapeutic target for controlling tumor spread by inhibiting EMT.
- Further research into these molecular pathways can lead to novel anti-metastatic strategies.

20.9K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

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...

02:17The Tumor Microenvironment
6.3K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

03:03mTOR Signaling and Cancer Progression
3.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:39lncRNA - Long Non-coding RNAs
7.5K
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...
