However, the underlying regulatory mechanisms of MALAT1 in sorafenib-resistant HCC cells remain unclear. In the present study, we demonstrated that 5-methylcytosine (m<sup>5</sup>C) methylation catalyzed by NSUN2 and ALYREF contributed to the RNA stability and upregulation of MALAT1. The NSUN2/ALYREF/MALAT1 signaling axis was activated in sorafenib-resistant cells, and the upregulation of MALAT1 inhibited sorafenib-induced ferroptosis to drive sorafenib resistance. Mechanistically, MALAT1 maintained the mRNA stability of SLC7A11 by directly binding to ELAVL1 and stimulating its cytoplasmic translocation. Furthermore, we explored a new synergetic strategy for the treatment of HCC by combining MALAT1 inhibitor MALAT1-IN1 with sorafenib. The results demonstrated that MALAT1-IN1 significantly enhanced sorafenib efficacy for the treatment of HCC both in vitro and in vivo.

The present study determined the global distribution, genomic classification, phylogeny, and monitor longitudinal resistome changes. During 1900-2024, a total of 1027 non-duplicate Morganella genomes have been reported from 49 countries. The countries with the highest number were China (433), the USA (143), and France (74). Through ANI distance analysis and core genome phylogeny, Morganella was reclassified into six species: M. morganii, M. sibonii, M. chanii, M. laugraudii, M. kristinii, M. psychrotolerans. Further analysis using cgMLST identified 87 distinct genetic clusters and 737 singleton strains, indicating a high level of multi-locus sequence type diversity and local clonal outbreaks. Bayesian evolutionary analysis revealed the most recent common ancestor year and potential global transmission routes. A total of 195 ARGs were carried by Morganella isolates, with each genome containing between 2 and 544 ARGs. The most common ARGs were associated with resistance to the following drug-classes: aminoglycosides, beta-lactam, chloramphenicol, sulfamides, and tetracycline. Twenty-one carbapenemase-encoding genes were identified in 22 countries, with bla<sub>NDM-1</sub>, bla<sub>KPC-2</sub>, bla<sub>IMP-27</sub>, bla<sub>OXA-48</sub>, bla<sub>NDM-5</sub>, bla<sub>NDM-7</sub>, and bla<sub>VIM-1</sub> being the most prevalent. Positive correlations were observed between ARGs and mobile genetic elements, like plasmids, ISs, and Tns, indicating frequent mobilization of certain ARGs by different mobile genetic elements (p < 0.05).

Importantly, combining drug treatment with fasting/FMDs can overcome acquired drug resistance which frequently emerges and reduces long-term treatment benefits. However, the mechanisms by which the FMD reverts resistance to CDK4/6i remain poorly understood. Here, Li and colleagues provide evidence that FMD cycles act as a wild card to reduce the activity of a signaling network that includes IGF-1, RAS, AKT, and mTOR-S6K to delay cancer progression and reverse the acquisition of drug resistance. These findings expand the mechanistic understanding of the FMD-mediated increase in drug efficacy and provide further evidence to support trials combining hormone therapy, CDK4/6 inhibitors, and FMD in breast cancer treatment.

Several factors contribute to explaining primary or secondary resistance. Among them, cancer cells, whose metabolism frequently relies on aerobic glycolysis, promote exhaustion of cytotoxic immune cells by diverting the glucose in the tumor microenvironment (TME) to their own profit, while secreting lactic acid that sustains the oxidative metabolism of immunosuppressive cells. Here, we propose to combine current treatment based on the use of immune checkpoint inhibitors (ICIs) with high doses of sodium citrate (SCT) because citrate inhibits cancer cell metabolism (by targeting both glycolysis and oxidative metabolism) and may active anti-tumor immune response. Indeed, as showed in preclinical studies, SCT reduces cancer cell growth, promoting cell death and chemotherapy effectiveness. Furthermore, since the plasma membrane citrate carrier pmCIC is mainly expressed in cancer cells and low or not expressed in immune and non-transformed cells, we argue that the inhibition of cancer cell metabolism by SCT may increase glucose availability in the TME, thus promoting functionality of anti-tumor immune cells. Concomitantly, the decrease in the amount of lactic acid in the TME may reduce the functionality of immunosuppressive cells. Preclinical studies have shown that SCT can enhance the anti-tumor immune response through an enhancement of T cell infiltration and activation, and a repolarization of macrophages towards a TAM1-like phenotype. Therefore, this simple and cheap strategy may have a major impact to increase the efficacy of current immunotherapies in human solid tumors and we encourage testing it in clinical trials.</div></div>","PeriodicalId":51022,"journal":{"name":"Drug Resistance Updates","volume":"78 ","pages":"Article 101177"},"PeriodicalIF":15.8,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142721172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
