Summary
MicroRNAs regulate gene expression and are crucial in cancer development, acting as oncogenes or tumor suppressors. This review explores microRNA processing and their posttranscriptional regulation in health and disease.
Area of Science:
- Molecular Biology
- Genetics
- Cancer Research
Background:
- MicroRNAs (miRNAs) are short non-coding RNAs regulating gene expression.
- They are implicated in diverse physiological processes and nearly all cancers.
- miRNAs can function as oncogenes or tumor suppressors in tumorigenesis.
Purpose of the Study:
- To review the microRNA processing pathway.
- To highlight recent insights into posttranscriptional regulation of miRNA expression.
- To underscore the significance of miRNA regulation in cancer.
Main Methods:
- Literature review of microRNA biogenesis and function.
- Analysis of transcriptional and posttranscriptional regulatory mechanisms.
- Synthesis of current understanding of miRNA roles in cancer.
Main Results:
- MicroRNA dysregulation is linked to tumorigenesis processes like metastasis and proliferation.
- Mechanisms of miRNA regulation at transcriptional and posttranscriptional levels are complex.
- Understanding these mechanisms is key to cancer research.
Conclusions:
- MicroRNAs are critical regulators in both normal physiology and cancer.
- Further research into miRNA regulation mechanisms is essential for therapeutic strategies.
- This review provides insights into miRNA processing and posttranscriptional control.

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.

02:55The Nucleolus
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,...
