Summary
MicroRNAs (miRNAs) regulate tumor angiogenesis by targeting key signaling pathways. Understanding these microRNAs offers potential for novel cancer therapies targeting tumor blood vessel formation.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Angiogenesis is crucial for tumor growth and a target for cancer drug therapy.
- MicroRNAs (miRNAs) are short non-coding RNAs that regulate gene expression.
- Dysregulation of angiogenesis contributes to cancer progression.
Purpose of the Study:
- To review the current understanding of miRNAs involved in regulating tumor angiogenesis.
- To identify the targets of these miRNAs within angiogenic signaling pathways.
- To highlight the therapeutic potential of targeting miRNAs in cancer treatment.
Main Methods:
- Literature review of studies on miRNAs and tumor angiogenesis.
- Analysis of miRNA targeting mechanisms for angiogenic factors and kinases.
- Examination of miRNA interactions with VEGF, TSP-1, RTKs, HIF, and ROS.
Main Results:
- miRNAs modulate both pro-angiogenic (e.g., VEGF) and anti-angiogenic (e.g., TSP-1) signals.
- miRNAs target receptor tyrosine kinases (RTKs) and hypoxia-inducible factor (HIF).
- miRNA activity is influenced by reactive oxygen species (ROS), affecting angiogenesis.
Conclusions:
- miRNAs play a critical role in controlling tumor angiogenesis.
- Targeting specific miRNAs presents a promising therapeutic strategy for cancer patients.
- Further research into miRNA-angiogenesis interactions can improve cancer treatment outcomes.

01:24Regulation of Angiogenesis and Blood Supply
4.0K
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...

4.3K
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...

01:10Mechanism of Angiogenesis
7.7K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

02:17The Tumor Microenvironment
8.2K
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
10.2K
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...
