Non-Coding RNA
|June 5, 2018
Summary
Non-coding RNAs (ncRNAs) within exosomes show promise as cancer biomarkers and therapeutic targets. These tiny vesicles protect ncRNAs in bodily fluids, aiding in cancer diagnostics, prognostics, and drug delivery strategies.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Non-coding RNAs (ncRNAs), including microRNAs and long non-coding RNAs, are critical regulators frequently dysregulated in cancer.
- Exosomes, extracellular vesicles derived from endosomes, play significant roles in cancer progression and metastasis.
- Exosomes encapsulate ncRNAs, shielding them from degradation in bodily fluids, making them valuable diagnostic and prognostic indicators.
Purpose of the Study:
- To review the clinical relevance of exosomal ncRNAs in cancer.
- To explore the diagnostic and prognostic potential of exosomal ncRNAs.
- To examine the therapeutic applications of exosomal ncRNAs, including drug delivery.
Main Methods:
- Literature review focusing on exosomal ncRNAs in cancer.
- Analysis of current research on the role of ncRNAs in cancer development and metastasis.
- Examination of exosome biogenesis, cargo loading, and intercellular communication.
Main Results:
- Exosomal ncRNAs are altered in a tissue- and stage-specific manner in various cancers.
- The protective nature of exosomes enhances the stability of ncRNAs in circulation.
- Exosomes can be engineered for targeted delivery of therapeutic ncRNAs.
Conclusions:
- Exosomal ncRNAs represent a promising source for cancer diagnostics and prognostics.
- The natural ncRNA-carrying capacity of exosomes offers potential for novel cancer therapies.
- Targeting exosomal ncRNAs may lead to innovative strategies for cancer treatment.

02:39lncRNA - Long Non-coding RNAs
10.0K
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...

18.7K
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...

7.7K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...
