Summary
MicroRNAs (miRNAs) regulate gene expression and are crucial for development. Deregulated miRNAs are implicated in cancer initiation and progression, showing promise as diagnostic biomarkers.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are small, non-coding RNAs regulating gene expression post-transcriptionally.
- They are vital for development, homeostasis, and cellular processes like proliferation and apoptosis.
- Aberrant miRNA expression is linked to cancer development and progression.
Purpose of the Study:
- To review the role of deregulated microRNAs in solid tumors.
- To highlight the prognostic potential of microRNA expression signatures in cancer patients.
Main Methods:
- Literature review of studies investigating microRNA expression in various solid tumors.
- Analysis of the functional roles of microRNAs in cancer biology.
- Evaluation of microRNA signatures as potential biomarkers.
Main Results:
- Differential expression of specific miRNAs is observed between malignant tumors and normal tissues.
- MicroRNA deregulation is a significant factor in tumorigenesis and cancer advancement.
- MicroRNA expression profiling is a promising avenue for novel cancer biomarker development.
Conclusions:
- MicroRNAs are key regulators with significant roles in cancer.
- Investigating deregulated miRNAs in solid tumors offers potential for improved cancer diagnostics and prognostics.
- MicroRNA-based biomarkers could enhance clinical management of cancer patients.

3.1K
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...

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.

4.0K
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...

7.5K
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...
