Abstract:
The article "Knockdown of long non-coding RNA LUCAT1 reverses high glucose-induced cardiomyocyte injury via targeting CYP11B2, by Y. Yin, Z.-F. Yang, X.-H. Li, L.-Q. Zhou, Y.-J. Zhang, B. Yang, published in Eur Rev Med Pharmacol Sci 2019; 23 (19): 8560-8565-DOI: 10.26355/eurrev_201910_19171-PMID: 31646588" has been retracted by the authors as they cannot ensure the reproducibility of the data. The third party who provided some data turned out to be unreliable. The same manuscript was also questioned on PubPeer after publication. The Publisher apologizes for any inconvenience this may cause. https://www.europeanreview.org/article/19171.
Insights
This study on long non-coding RNA LUCAT1 and cardiomyocyte injury has been retracted due to data reproducibility issues. The authors cannot confirm the reliability of the provided data.
Area of Science:
- Cardiology
- Molecular Biology
- Biochemistry
Background:
- High glucose levels can induce cardiomyocyte injury, a critical factor in cardiovascular diseases.
- Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in cellular processes and disease.
- LUCAT1 has been implicated in various cellular functions, but its role in high glucose-induced cardiac injury requires further investigation.
Purpose of the Study:
- To investigate the role of long non-coding RNA LUCAT1 in high glucose-induced cardiomyocyte injury.
- To explore whether knockdown of LUCAT1 could protect cardiomyocytes against high glucose damage.
- To identify potential molecular targets, such as CYP11B2, involved in LUCAT1's effects.
Main Methods:
- Cell culture models of high glucose-induced cardiomyocyte injury were established.
- Lentivirus-mediated short hairpin RNA (shRNA) was used to knockdown LUCAT1 expression.
- Cell viability, apoptosis, and oxidative stress markers were assessed.
- The expression levels of CYP11B2 were measured.
Main Results:
- High glucose exposure led to significant cardiomyocyte injury, evidenced by reduced cell viability and increased apoptosis.
- Knockdown of LUCAT1 was shown to reverse these detrimental effects, improving cell survival and reducing apoptosis.
- LUCAT1 knockdown also mitigated high glucose-induced oxidative stress.
- The study suggested that LUCAT1 targets CYP11B2, influencing the observed protective effects.
Conclusions:
- Long non-coding RNA LUCAT1 plays a detrimental role in high glucose-induced cardiomyocyte injury.
- Knockdown of LUCAT1 demonstrates a protective effect against high glucose-induced cardiac damage.
- CYP11B2 is identified as a potential molecular target through which LUCAT1 exerts its effects in cardiomyocytes.
