Summary
Hypoxia alters exosomes, releasing non-coding RNAs that drive cancer progression. These tumor-derived exosomal non-coding RNAs show promise as cancer biomarkers in body fluids.
Area of Science:
- Cancer Biology
- Extracellular Vesicles
- Molecular Oncology
Background:
- Exosomes, secreted by cells, carry molecular cargo reflecting their origin.
- Exosome-mediated cell communication is vital for cancer progression.
- Tumor hypoxia, a pro-cancerous microenvironment feature, modifies exosome release and content.
Purpose of the Study:
- To review how non-coding RNAs within exosomes from hypoxic tumors regulate cancer behavior.
- To highlight the role of these non-coding RNAs in cancer biology and tumor microenvironment remodeling.
- To discuss the potential of these molecules as diagnostic and prognostic biomarkers.
Main Methods:
- Literature review focusing on studies of exosomes, non-coding RNAs, and hypoxia in cancer.
- Analysis of research on the impact of hypoxia on exosome content and function.
- Examination of evidence linking exosomal non-coding RNAs to cancer phenotypes and biomarker potential.
Main Results:
- Hypoxia significantly alters the release and molecular cargo of tumor-derived exosomes.
- Non-coding RNAs within these exosomes are key regulators of cancer aggressiveness and tumor microenvironment.
- Hypoxic tumor-derived exosomal non-coding RNAs are detectable in body fluids, indicating biomarker utility.
Conclusions:
- Exosomes secreted under hypoxic conditions play a crucial role in cancer progression via non-coding RNA transfer.
- Non-coding RNAs shuttled by hypoxic tumor exosomes represent critical mediators of cancer biology.
- These exosomal non-coding RNAs hold significant potential as accessible biomarkers for cancer diagnosis and prognosis.

3.6K
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...

02:17The Tumor Microenvironment
7.5K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

02:39lncRNA - Long Non-coding RNAs
9.6K
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...

01:24Regulation of Angiogenesis and Blood Supply
3.2K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

9.7K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
