Summary
Long noncoding RNA RP11-334E6.12 is upregulated in breast cancer and linked to poor survival. This lncRNA promotes tumor progression by enhancing proliferation, migration, and invasion via the STAT3 pathway.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- RP11-334E6.12 is a long noncoding RNA (lncRNA) with unknown function in breast cancer.
- Its role in tumorigenesis has not been previously investigated.
Purpose of the Study:
- To investigate the role and mechanism of RP11-334E6.12 in breast cancer progression.
- To determine the association between RP11-334E6.12 expression and patient survival.
Main Methods:
- Utilized The Cancer Genome Atlas (TCGA) database to identify dysregulated lncRNAs.
- Assessed RP11-334E6.12 levels in breast cancer tissues and cell lines.
- Performed proliferation, migration, and invasion assays to evaluate cellular functions.
Main Results:
- RP11-334E6.12 was significantly upregulated in breast cancer.
- Higher RP11-334E6.12 expression correlated with poorer overall survival.
- RP11-334E6.12 promoted breast cancer cell proliferation, migration, and invasion.
- RP11-334E6.12 activates the STAT3 pathway, promoting epithelial-mesenchymal transition.
Conclusions:
- RP11-334E6.12 is associated with breast cancer progression.
- RP11-334E6.12 promotes breast cancer cell proliferation, migration, and invasion by activating the STAT3 pathway.
- RP11-334E6.12 may serve as a potential therapeutic target for breast cancer.

lncRNA - Long Non-coding RNAs
9.6K
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...

mTOR Signaling and Cancer Progression
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.

PI3K/mTOR/AKT Signaling Pathway
5.1K
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...

The Ras Gene
6.9K
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.

Abnormal 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...
