Huber² and Steffen Gay³, ¹Center of Experimental Rheumatology, University Hospital Zurich and Zurich Center of Integrative Human Physiology (ZIHP), Zurich, Switzerland, ²Department of Internal Medicine, University Hospital Zurich, Zurich, Switzerland, ³Center of Experimental Rheumatology, University Hospital Zurich, Zurich, Switzerland, ⁴Department of Rheumatology, University Hospital Zurich, Zurich, Switzerland
Background/Purpose: Long noncoding RNAs (lncRNA, >200nt) have recently emerged as regulators of gene expression functioning as signals, decoys, guides or scaffolds for transcription factors and/or…

Michel¹ and Michel Neidhart¹, ¹Center of Experimental Rheumatology, University Hospital Zurich, Zurich, Switzerland, ²Center of Experimental Rheumatology, University Hospital Zurich and Zurich Center of Integrative Human Physiology (ZIHP), Zurich, Switzerland
Background/Purpose: Previously we reported that methyl supplementation can reverse the global hypomethylation of rheumatoid arthritis synovial fibroblasts (RASF) and attenuate their aggressive behaviour. Now we…

Background/Purpose: Lupus nephritis (LN) is a common manifestation of SLE associated with significant morbidity and mortality. microRNAs (miRs) are small non-coding RNAs that regulate translation…

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
