Summary
This summary is machine-generated.Long non-coding RNA CCAT1 promotes radioresistance in lung adenocarcinoma (LUAD). Targeting CCAT1 may enhance radiotherapy effectiveness for LUAD patients.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Long non-coding RNAs (lncRNAs) are key regulators in biological processes and cancer development.
- LncRNA CCAT1 is implicated in various cancers, but its role in lung adenocarcinoma (LUAD) radioresistance is unknown.
Purpose Of The Study
- To investigate the role of CCAT1 in LUAD radioresistance.
- To identify CCAT1 as a potential therapeutic target for improving LUAD radiotherapy.
Main Methods
- Analysis of The Cancer Genome Atlas (TCGA) database for radioresistance-related lncRNAs in LUAD.
- In vitro experiments using LUAD cell lines (NCI-H1299 and A549).
- Loss-of-function (knockdown) and gain-of-function (overexpression) studies of CCAT1.
Main Results
- CCAT1 is highly expressed in LUAD and correlates with poor prognosis and radioresistance.
- Radiation treatment increases CCAT1 expression in LUAD cell lines.
- CCAT1 knockdown reduces proliferation and migration while increasing apoptosis in irradiated LUAD cells.
- CCAT1 overexpression has opposite effects, enhancing radioresistance.
Conclusions
- CCAT1 plays a significant role in promoting radioresistance in lung adenocarcinoma.
- CCAT1 represents a potential target for enhancing LUAD radiotherapy sensitization.

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...
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
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.
Ras is a...
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...
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
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.
The mTOR pathway or the...
