Summary
MicroRNAs (miRNAs) regulate gene expression and are crucial in disease. This review focuses on oncogenic miRNAs, highlighting their role in cancer development and progression.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are non-coding RNAs regulating gene expression post-transcriptionally.
- Aberrant miRNA expression is linked to various diseases, including cancer.
- Oncogenic and tumor suppressor miRNAs play critical roles in carcinogenesis.
Purpose of the Study:
- To review the function of oncogenic microRNAs (miRNAs) in malignancy.
- To explore the association between altered miRNA expression and cancer development.
- To highlight the impact of miRNAs on metastasis and treatment response.
Main Methods:
- Literature review focusing on oncogenic miRNAs.
- Analysis of post-transcriptional gene regulation by miRNAs.
- Synthesis of data on miRNA involvement in carcinogenesis.
Main Results:
- Oncogenic miRNAs promote malignancy through aberrant gene expression.
- Altered miRNA levels correlate with cancer progression, metastasis, and treatment outcomes.
- Specific miRNAs function as oncogenes, driving malignant transformation.
Conclusions:
- MicroRNAs are key regulators in cancer biology.
- Targeting oncogenic miRNAs offers potential therapeutic strategies.
- Understanding miRNA dysregulation is vital for cancer research.

MicroRNAs
4.3K
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 the pre-miRNA...

mTOR Signaling and Cancer Progression
5.1K
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.

Abnormal Proliferation
5.4K
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...
