LncRNA LINC00969 modified by METTL3 attenuates papillary thyroid cancer progression in an m6A-dependent manner.
Background: The long non-coding RNA (lncRNA) LINC00969 is involved in human disease progression, and n6-methyladenosine (m6A) modification of lncRNAs in cancer has been proven to be a key regulatory mechanism. However, our understanding of its effects and mechanisms of action in papillary thyroid carcinoma (PTC) remains limited.
Objectives: This study aimed to elucidate the role of methyltransferase-like 3 (METTL3)-induced m6A modification of LINC00969 in PTC tumorigenesis.
Material and methods: Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed to analyze LINC00969 and METTL3 mRNA levels in PTC. The regulation of LINC00969 by METTL3 was confirmed using cell function experiments, molecular biology assays and bioinformatics analysis. LINC00969 stabilization analysis was performed to verify the regulatory roles of METTL3 and LINC00969.
Results: LINC00969 expression was downregulated in PTC tissues. Increased LINC00969 expression inhibited the invasion, growth and migration of PTC cells. METTL3 downregulation in PTC mediated the m6A modification of LINC00969, increasing its stability. Furthermore, METTL3 levels were downregulated in PTC, and its silencing partially reversed the inhibitory effect of LINC00969 overexpression on PTC cell malignancy.
Conclusions: LINC00969 overexpression inhibits PTC cell malignancy via METTL3-mediated m6A modification. These findings suggest that METTL3-m6A-LINC00969 is a promising therapeutic target for PTC.
期刊介绍：
Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly.
Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff.
Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj.
Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker.
The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition.
In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus.
Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
