Summary
Tumor cell plasticity drives cancer metastasis, a major cause of cancer deaths. Non-coding RNAs (ncRNAs) regulate this plasticity, offering potential diagnostic and therapeutic targets for overcoming metastasis.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Tumor metastasis is a primary cause of cancer-related mortality.
- Tumor cell plasticity, involving processes like cancer stem cell differentiation and epithelial-mesenchymal transition (EMT), is crucial for metastasis.
- Non-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), are increasingly recognized for their role in regulating tumor cell plasticity.
Purpose of the Study:
- To elucidate the regulatory mechanisms of non-coding RNAs in tumor cell plasticity.
- To highlight the significance of understanding ncRNA-mediated plasticity for developing novel cancer therapies.
- To identify potential diagnostic markers and therapeutic targets for combating cancer metastasis.
Main Methods:
- Review of current literature on tumor cell plasticity and ncRNA functions.
- Analysis of studies linking ncRNAs (miRNAs, lncRNAs) to key plasticity processes (CSC differentiation, EMT/MET).
- Synthesis of evidence on the role of ncRNAs in enabling invasion and distant metastasis.
Main Results:
- ncRNAs, particularly miRNAs and lncRNAs, are integral regulators of tumor cell plasticity.
- These ncRNAs influence critical transitions like EMT and MET, facilitating cancer cell invasion and metastasis.
- Dysregulation of ncRNAs contributes to the development of metastatic phenotypes.
Conclusions:
- Understanding ncRNA regulation of tumor cell plasticity is essential for advancing cancer treatment.
- Targeting ncRNAs involved in plasticity presents a promising strategy for inhibiting metastasis.
- Further research into ncRNA mechanisms can lead to improved diagnostic tools and therapies for metastatic cancers.

02:39lncRNA - Long Non-coding RNAs
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 (lncRNA)...
02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
03:03mTOR Signaling and Cancer Progression
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.

01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
