Summary
MicroRNAs (miRNAs), small RNA molecules, are involved in cancer progression and metastasis. Monitoring miRNA expression aids in early cancer detection and offers potential therapeutic targets for cancer treatment.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are small RNA molecules regulating gene expression post-transcriptionally.
- miRNAs play crucial roles in biological processes including proliferation, apoptosis, and oncogenesis.
- Dysregulated miRNA expression is implicated in various stages of cancer development and progression.
Purpose of the Study:
- To review the role of miRNAs in cancer.
- To highlight miRNAs as potential diagnostic markers for early cancer detection.
- To explore miRNA-targeted therapies for cancer treatment.
Main Methods:
- Literature review of studies on miRNA in cancer.
- Analysis of miRNA involvement in cancer progression and metastasis.
- Examination of miRNA expression profiling for diagnostic and prognostic potential.
Main Results:
- miRNAs can act as tumor suppressors or oncogenes (oncomirs).
- Changes in miRNA expression profiles correlate with cancer presence and progression.
- Targeting deregulated miRNAs presents a promising therapeutic strategy.
Conclusions:
- miRNAs are critical regulators in cancer biology.
- miRNA expression profiling offers a valuable tool for cancer diagnostics and prognostics.
- miRNA-based therapies hold significant potential for future cancer treatment.

01:22MicroRNAs
3.2K
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...

7.9K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:39lncRNA - Long Non-coding RNAs
9.0K
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...

03:03mTOR Signaling and Cancer Progression
3.9K
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.

17.2K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

02:23Abnormal Proliferation
4.7K
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...
