Summary
Long noncoding RNA LUCAT1 promotes choroidal melanoma (CM) progression by activating proliferation and metastasis. This study reveals the ELF1/LUCAT1/miR-514a/b-3p/RBX1 axis, offering new therapeutic targets for CM.
Area of Science:
- Oncology
- Molecular Biology
- Gene Regulation
Background:
- Long noncoding RNAs (lncRNAs) regulate gene expression and biological functions.
- The role of lncRNA LUCAT1 in choroidal melanoma (CM) is currently unknown.
Purpose of the Study:
- To investigate the expression and function of LUCAT1 in CM.
- To elucidate the molecular mechanism underlying LUCAT1's role in CM progression.
Main Methods:
- Quantitative real-time PCR (qRT-PCR) for gene expression analysis.
- Cell proliferation, apoptosis, migration, and invasion assays.
- Bioinformatics, RNA immunoprecipitation, pull-down, and luciferase reporter assays to confirm molecular interactions.
Main Results:
- LUCAT1 expression is elevated in CM cells and promotes proliferation, metastasis, and epithelial-mesenchymal transition.
- ELF1 acts as a transcription activator for LUCAT1.
- LUCAT1 functions as a competing endogenous RNA (ceRNA) by modulating the miR-514a/b-3p/RBX1 axis, where miR-514a/b-3p inhibits and RBX1 promotes CM progression.
Conclusions:
- LUCAT1 is a novel oncogenic lncRNA and a promoter in choroidal melanoma.
- The ELF1/LUCAT1/miR-514a/b-3p/RBX1 axis represents a potential therapeutic target for CM treatment.

01:20The Retinoblastoma Gene
4.6K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

01:24Regulation of Angiogenesis and Blood Supply
3.3K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

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...

13.0K
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...
