Summary
MicroRNA-497-5p (miR-497) acts as a tumor suppressor in aggressive angiosarcoma (AS). Overexpressing miR-497 inhibits AS cell viability, migration, and tumor formation by targeting genes like VAT1.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Angiosarcoma (AS) is an aggressive vascular cancer with limited treatment options.
- DICER1, crucial for microRNA (miRNA) biogenesis, is implicated in AS development.
- Identifying novel therapeutic targets in AS is critical.
Approach:
- Investigated the tumor-suppressive role of miRNAs in AS, focusing on microRNA-497-5p (miR-497).
- Utilized RNA-sequencing, patient data, and prediction algorithms to identify miR-497 targets.
- Validated direct regulation of CCND2, CDK6, and VAT1 by miR-497.
Key Points:
- miR-497 significantly suppressed AS cell viability, migration, and tumor formation.
- Validated miR-497 directly targets CCND2, CDK6, and VAT1.
- VAT1 inhibition using Neocarzilin A reduced AS cell migration.
Conclusions:
- miR-497 functions as a tumor suppressor in angiosarcoma.
- Identified key miR-497 target genes, including VAT1, involved in AS pathogenesis.
- Suggests VAT1 as a potential therapeutic target for angiosarcoma treatment.

3.0K
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...

3.8K
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.

2.6K
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...

02:39lncRNA - Long Non-coding RNAs
8.6K
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...

02:23Master Transcription Regulators
6.9K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

01:10Mechanism of Angiogenesis
5.5K
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...
