Summary
Cancer cells exploit genome structure changes for tumorigenesis via epigenetic alterations. MicroRNAs play a key role in these cancer-related epigenetic changes, acting as both cause and consequence.
Area of Science:
- Molecular Biology
- Genetics
- Cancer Research
Background:
- Cancer cells reprogram transcriptional networks by altering genome's 3D structure.
- Epigenetic phenomena involve heritable chromatin modifications and RNA-protein-DNA complexes.
- Deregulation of non-coding RNA is linked to cancer-related epigenetic alterations.
Purpose of the Study:
- To review recent findings on microRNAs in aberrant epigenetic regulation of cancer cells.
- To highlight the role of microRNAs in cancer-associated epigenetic reprogramming.
Main Methods:
- Literature review of recent scientific findings.
- Analysis of studies implicating microRNAs in cancer epigenetics.
Main Results:
- MicroRNAs are implicated in the aberrant epigenetic regulation observed in cancer cells.
- Evidence suggests microRNAs are involved in both causing and resulting from cancer-related epigenetic alterations.
Conclusions:
- MicroRNAs are significant players in the epigenetic dysregulation driving tumorigenesis.
- Understanding microRNA involvement is crucial for targeting cancer's epigenetic vulnerabilities.

MicroRNAs
24.3K
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...

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation
3.9K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

lncRNA - Long Non-coding RNAs
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...

Cancer
54.6K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
