Summary
MicroRNAs (miRNAs) are small RNAs regulating gene expression. Their dysregulation is key in cancer, offering potential as biomarkers and therapeutic targets for various malignancies.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) were identified in 1993 and found to be highly conserved in 2000.
- These small RNA molecules regulate gene expression and protein synthesis.
- miRNAs play critical roles in malignancy, acting as tumor suppressors and oncogenes.
Purpose of the Study:
- To review the current understanding of miRNA function in cancer.
- To explore the role of miRNA dysregulation in tumor formation, maintenance, and metastasis.
- To discuss the potential of miRNAs as biomarkers and therapeutic agents in oncology.
Main Methods:
- Literature review of scientific publications on microRNAs and cancer.
- Synthesis of current knowledge on molecular mechanisms of miRNA action.
- Analysis of studies investigating miRNA dysregulation in tumorigenesis and metastasis.
Main Results:
- miRNAs are crucial regulators of gene expression with significant roles in cancer.
- Dysregulated miRNAs are implicated in tumor initiation, progression, and metastasis.
- miRNAs show promise as biomarkers for cancer type and grade.
- miRNA-based therapies are being developed for various malignancies.
Conclusions:
- MicroRNAs are fundamental to understanding cancer biology.
- Targeting miRNAs offers a promising avenue for cancer diagnosis and treatment.
- Further research into miRNA mechanisms and applications is warranted.

01:22MicroRNAs
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 the pre-miRNA...

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...
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)...
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.
