Non-Coding RNA
|November 4, 2020
Summary
Long non-coding RNAs (lncRNAs) are vital in cellular biology. Nuclear Enriched Abundant Transcript 1 (NEAT1) drives cancer progression and chemoresistance by forming paraspeckles, offering novel drug targets.
Area of Science:
- Molecular Biology
- Cancer Biology
- RNA Biology
Background:
- Non-coding RNAs (ncRNAs) were once dismissed as transcriptional noise.
- ncRNAs are now recognized as crucial in cellular processes and disease.
- Structural long non-coding RNAs (lncRNAs) are increasingly important as their roles are elucidated.
Purpose of the Study:
- To review the multifaceted roles of NEAT1 in cancer progression.
- To explore NEAT1's mechanisms in mediating chemoresistance.
- To identify NEAT1 as a potential therapeutic target in oncology.
Main Methods:
- Literature review focusing on NEAT1 and cancer.
- Analysis of NEAT1's structural functions, particularly paraspeckle formation.
- Examination of NEAT1's impact on drug resistance pathways.
Main Results:
- NEAT1 is a critical structural lncRNA in cancer development.
- NEAT1 facilitates tumor drug resistance through paraspeckle formation.
- NEAT1 influences multiple cancer-related biological pathways.
Conclusions:
- NEAT1 plays a significant role in cancer progression and chemoresistance.
- Understanding NEAT1's mechanisms provides insights beyond protein-centric research.
- NEAT1 represents a promising target for novel cancer therapies.

Adaptive Mechanisms in Cancer Cells
6.5K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Destabilization of Microtubules
3.3K
The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...

Metastasis
6.2K
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...

The Spindle Assembly Checkpoint
3.5K
The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

Cancer-Critical Genes II: Tumor Suppressor Genes
8.9K
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.
Such genes that act...

Cancer Stem Cells and Tumor Maintenance
5.5K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
