Summary
Long non-coding RNA LINC00958 promotes osteosarcoma progression by inhibiting microRNA miR-4306, leading to increased expression of CEMIP and poorer patient prognosis.
Area of Science:
- Oncology
- Molecular Biology
- Gene Regulation
Background:
- Osteosarcoma is a primary bone malignancy with a complex molecular landscape.
- Understanding the regulatory mechanisms driving osteosarcoma progression is crucial for developing targeted therapies.
Purpose of the Study:
- To elucidate the functional role of LINC00958 in osteosarcoma.
- To investigate the interaction between LINC00958, miR-4306, and CEMIP in osteosarcoma pathogenesis.
- To assess the prognostic value of LINC00958 in osteosarcoma patients.
Main Methods:
- Bioinformatic analysis of gene expression data (GSE66673).
- Quantitative PCR (RT-qPCR), Western blot, and FISH assays to determine gene and protein expression and localization.
- Dual-luciferase reporter assays and RNA immunoprecipitation (RIP) to confirm molecular interactions.
- In vitro (gain/loss-of-function) and in vivo (xenograft) experiments to evaluate cellular functions and tumorigenicity.
Main Results:
- LINC00958 expression was significantly upregulated in osteosarcoma tissues and negatively correlated with miR-4306 levels.
- LINC00958 directly inhibited miR-4306, which in turn targets CEMIP.
- Silencing LINC00958 suppressed osteosarcoma cell proliferation, migration, invasion, and tumorigenesis, while inhibiting miR-4306 reversed these effects.
- High LINC00958 expression correlated with poor overall survival in osteosarcoma patients.
Conclusions:
- LINC00958 acts as an oncogenic lncRNA in osteosarcoma.
- The LINC00958/miR-4306/CEMIP axis is a key regulator of osteosarcoma progression.
- LINC00958 may serve as a potential therapeutic target and prognostic biomarker for osteosarcoma.

9.3K
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...

3.3K
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...

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

4.0K
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.

4.4K
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...
