Summary
MicroRNAs (miRNAs), small non-coding RNAs, regulate gene expression and are crucial in cell fate. Their deregulation is linked to cancer, offering potential as biomarkers and therapeutic targets.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Discovery of gene regulatory capacity in non-functional genome components revolutionized molecular biology.
- MicroRNAs (miRNAs) are conserved, small non-coding RNAs involved in regulating gene expression across biological processes.
- miRNA deregulation is implicated in various pathologies, notably cancer.
Purpose of the Study:
- To review current knowledge on microRNA involvement in cancer.
- To highlight the role of miRNAs as oncogenes or tumor suppressors in tumorigenesis.
- To discuss the potential of miRNAs as diagnostic, prognostic, and predictive biomarkers in oncology.
Main Methods:
- Literature review of studies on microRNA function and cancer.
- Analysis of evidence linking miRNA aberrant expression to tumor initiation, development, and metastasis.
- Examination of research on miRNA-based diagnostics and therapeutics.
Main Results:
- MicroRNAs play a causal role in cancer, acting as oncogenes or tumor suppressors.
- Aberrant miRNA expression is a hallmark of human tumors.
- miRNAs show promise as biomarkers for cancer diagnosis and prognosis.
Conclusions:
- MicroRNAs are integral to cancer development and progression.
- miRNA-based therapies, alone or combined with existing treatments, offer potential for improved cancer response and cure rates.
- Further research into miRNA involvement in cancer is warranted for clinical applications.

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...

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.

01:06Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

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...
