Abstract
Antisense oligonucleotides (ASONs)-based therapeutics offers tremendous promise for the treatment of diverse diseases. However, there is still a need to develop ASONs with enhanced stability against enzymes, improved drug delivery, and enhanced biological potency. In this study, we propose a novel anisamide (AA)-conjugated hairpin oligonucleotide prodrug loading with chemotherapeutic agent (doxorubicin, DOX) (AA-loop-ASON/DOX) for oncotherapy. Results indicated that the introduction of a hairpin conformation and AA ligand in prodrug significantly improved the stability against enzymatic hydrolysis, as well as the cellar uptake of ASONs and DOX. The incorporation of disulfide bonds could trigger mechanical opening, resulting in the release of ASON and DOX in response to the intracellular glutathione (GSH) in tumors. Moreover, the composite of DOX-loading ASONs prodrug exhibited a robust and selective inhibition of tumor cell proliferation. This paper introduces a novel design concept for nucleic acid-based therapeutics, aiming to enhance the delivery of drug and improve biological effectiveness.

Abstract
Antisense oligonucleotides (ASONs) have proven potential for the treatment of various diseases. However, their limited bioavailability restricts their clinical application. New structures with improved enzyme resistance stability and efficient drug delivery are needed. In this work, we propose a novel category of ASONs bearing anisamide conjugation at phosphorothioate sites for oncotherapy. ASONs can be conjugated with the ligand anisamide very efficiently and flexibly in a solution. The conjugation sites and the ligand amount both influence anti-enzymatic stability and cellular uptake, resulting in changes in antitumor activity that are detectable by cytotoxicity assay. The conjugate with double anisamide (T6) was identified as the optimal conjugate, and its antitumor activity and the underlying mechanism were examined further in vitro and in vivo. This paper presents a new strategy for the design of nucleic acid-based therapeutics with improved drug delivery and biophysical and biological efficacy.

[PMID: 36461116 PMCID: PMC9716549 DOI: 10.1186/s40104-022-00795-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 10/11/2022] [Indexed: 12/05/2022] Open
Abstract
BACKGROUND N6-methyladenosine (m6A) is an abundant post-transcriptional RNA modification that affects various biological processes. The fat mass and obesity-associated (FTO) protein, a demethylase encoded by the FTO gene, has been found to regulate adipocyte development in an m6A-dependent manner in multiple species. However, the effects of the m6A methylation and FTO demethylation functions on chicken adipogenesis remain unclear. This study aims to explore the association between m6A modification and chicken adipogenesis and the underlying mechanism by which FTO affects chicken preadipocyte development. RESULTS The association between m6A modification and chicken lipogenesis was assessed by treating chicken preadipocytes with different doses of methyl donor betaine and methylation inhibitor cycloleucine. The results showed that betaine significantly increased methylation levels and inhibited lipogenesis, and the inverse effect was found in preadipocytes after cycloleucine treatment. Overexpression of FTO significantly inhibited m6A levels and promoted proliferation and differentiation of chicken preadipocytes. Silencing FTO showed opposite results. Mechanistically, FTO overexpression increased the expression of catenin beta 1 (CTNNB1) by improving RNA stability in an m6A-dependent manner, and we proved that FTO could directly target CTNNB1. Furthermore, CTNNB1 may be a positive regulator of adipogenesis in chicken preadipocytes. CONCLUSIONS m6A methylation of RNA was negatively associated with adipogenesis of chicken preadipocytes. FTO could regulate CTNNB1 expression in a demethylation manner to promote lipogenesis.
