Summary
Long non-coding RNA RNCR3 (LINC00599) is upregulated in glioma and promotes tumor progression. RNCR3 knockdown inhibits glioma cell proliferation and invasion, potentially through the Akt/GSK-3β pathway.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Long non-coding RNAs (lncRNAs) are implicated in human cancer development.
- The role of RNCR3 (LINC00599) in glioma pathogenesis requires further investigation.
Purpose of the Study:
- To elucidate the biological role and molecular mechanisms of RNCR3 in glioma development.
- To determine the association between RNCR3 expression and glioma patient outcomes.
Main Methods:
- Quantitative analysis of RNCR3 expression in glioma tissues versus normal tissues.
- In vitro studies using U87 and U251 glioma cell lines with RNCR3 knockdown.
- Western blot analysis to assess protein expression levels in the Akt/GSK-3β signaling pathway.
Main Results:
- RNCR3 expression is significantly elevated in glioma tissues and correlates with tumor progression and poor survival.
- RNCR3 knockdown impairs glioma cell proliferation and invasion, inducing G1 phase arrest.
- Knockdown of RNCR3 reduces phosphorylation of Akt and GSK-3β.
Conclusions:
- RNCR3 acts as an oncogenic lncRNA in glioma.
- RNCR3 regulates glioma cell proliferation, cell cycle, and invasion, potentially via the Akt/GSK-3β signaling pathway.

9.7K
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...

4.5K
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.

5.2K
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...

02:23Abnormal Proliferation
5.0K
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...

7.0K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
