Summary
Long non-coding RNA PRR7-AS1 promotes osteosarcoma progression and metastasis by interacting with RNF2 and regulating MTUS1 transcription. This finding identifies PRR7-AS1 as a potential therapeutic target for osteosarcoma.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Osteosarcoma is a prevalent adolescent bone malignancy with high mortality and poor prognosis.
- Current understanding of osteosarcoma progression and effective treatments remains limited.
- This study investigates novel molecular mechanisms driving osteosarcoma.
Purpose of the Study:
- To identify and characterize the role of long non-coding RNA PRR7-AS1 (lncRNA PRR7-AS1) in osteosarcoma progression.
- To elucidate the molecular mechanisms by which lncRNA PRR7-AS1 influences osteosarcoma tumorigenesis and metastasis.
- To explore lncRNA PRR7-AS1 as a potential diagnostic and therapeutic target for osteosarcoma.
Main Methods:
- Analysis of osteosarcoma databases and clinical samples to determine the correlation between lncRNA PRR7-AS1 and osteosarcoma.
- In vitro and in vivo cell function assays to assess the impact of PRR7-AS1 on osteosarcoma proliferation and metastasis.
- RNA pulldown, RIP, GTRD, KnockTF, and ChIP-qPCR assays to identify and validate downstream targets RNF2 and MTUS1, and their regulatory mechanisms.
Main Results:
- A positive correlation was found between lncRNA PRR7-AS1 expression and osteosarcoma progression.
- Knockdown of PRR7-AS1 significantly inhibited osteosarcoma cell proliferation and metastasis both in vitro and in vivo.
- PRR7-AS1 was shown to interact with RNF2, which in turn inhibited MTUS1 transcription via histone modification, with MTUS1 confirmed as a direct downstream target.
Conclusions:
- lncRNA PRR7-AS1 acts as an oncogene promoting osteosarcoma progression and metastasis.
- The PRR7-AS1/RNF2/MTUS1 axis represents a novel molecular pathway in osteosarcoma.
- lncRNA PRR7-AS1 holds potential as a therapeutic target for osteosarcoma diagnosis and treatment.

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...

21.3K
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...

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.

4.5K
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...

3.6K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

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...
