Summary
MicroRNAs (miRNAs) show promise as biomarkers for early breast cancer detection and monitoring. Their stability and regulatory roles in gene expression offer new avenues for diagnosis and targeted therapies.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Breast cancer presents diverse subtypes with therapeutic resistance.
- Early detection requires reliable molecular biomarkers.
- MicroRNAs (miRNAs) are small non-coding RNAs involved in gene regulation.
Purpose of the Study:
- To review the role of miRNAs as biomarkers in breast cancer.
- To discuss miRNA origins, functions, stability, and turnover.
- To highlight miRNA utility in detection, monitoring, prognosis, and therapy.
Main Methods:
- Literature review of scientific articles on miRNAs and breast cancer.
- Analysis of miRNA origins (tissue and circulation).
- Evaluation of miRNA regulatory functions and stability.
Main Results:
- miRNAs play crucial roles in gene regulation and cancer pathogenesis.
- miRNAs are found in both tumor tissue and circulation.
- miRNA stability and turnover are key to their biomarker potential.
Conclusions:
- miRNAs are promising biomarkers for early breast cancer detection.
- miRNAs can be used for disease monitoring and prognosis.
- miRNAs represent potential therapeutic targets for breast cancer treatment.

MicroRNAs
2.9K
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
3.6K
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.

The Nucleolus
8.6K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
