Combination chemotherapy with PTT (chemo-PTT) offers multiple therapeutic advantages, involving synergistic effects, reduced side effects, and decreased drug toxicity. In this study, 2D titanium carbide (Ti₃C₂T_x) MXene nanosheets were encapsulated in a zeolitic imidazolate framework-8 (ZIF-8) to form (MX-ZIF-8) nanoparticles (NPs) for PTT applications. Sorafenib (SB), an anticancer drug was loaded onto MX-ZIF-8 and further modified with a liposomes (LPs) lipid bilayer to create (SB-MX-ZIF-8@LPs) nanocomposites. TEM imaging revealed that SB-MX-ZIF-8@LPs had a lamellar structure and spherical shape, with an average diameter of 75.2 nm and a zeta potential (ZP) of −8.4 ± 4.5 mV. Additionally, the PT stability, drug encapsulation, and in-vitro release kinetics of SB-MX-ZIF-8@LPs were assessed. These nanocomposites exhibited an impressive PT conversion efficiency of 55 % at 50 μg/mL under NIR irradiation. The cumulative release of SB from SB-MX-ZIF-8@LPs reached 86.15 % at pH 7.4 and 89.3 % at pH 4.8 under NIR over a period of 72 h, with an encapsulation efficiency of 87.34 %. MTT assays revealed strong cytotoxicity against HepG2 cells, with SB-MX-ZIF-8@LPs showing an IC₅₀ value of 2.7 μg/mL and inducing approximately 96 % total apoptosis. The SB-MX-ZIF-8@lip nanocomposite demonstrated excellent biological stability in a serum environment, retaining over 98 % of sorafenib and maintaining consistent particle size (∼347 nm) over 30 days. An in vivo xenograft study in BALB/c mice further demonstrated the efficacy of SB-MX-ZIF-8@LPs, with this treatment group showing the smallest tumor volume compared to other groups and a significantly higher tumor volume reduction than SB alone. Molecular docking studies indicated that SB exhibited strong binding affinities particularly with ABL1 (−8.7 kcal/mol) and EGFR (−9.3 kcal/mol). Docking interactions between MXene and SB, conducted using the Hdock Server, resulted in a docking score of −10.53, with one bond forming at a distance of 4 Å. These findings were consistent with experimental results, highlighting the favorable interaction between MXene and SB.

Moreover, there is a continued need for exploring novel and reliable tumor markers to achieve accurate diagnosis. Understanding the molecular complexity of cancer allows for the development of more effective and personalized treatments and facilitates the discovery of biomarkers that surpass traditional ones and assist in cancer diagnosis and monitoring disease progression and response to treatment. Recent studies exploring the complexity of cancer biology have identified a new form of cell death, known as cuproptosis, which is driven by the accumulation of copper and subsequent stress induced by dysregulation of copper homeostasis. Increased copper level enables cancer cells to maintain their accelerated growth rates and metastatic potential, yet these cells can evade cuproptosis. Long noncoding RNAs (lncRNAs) have been recognized for their pivotal role in different hallmarks of cancer, including resistance to cell death. They have been found to be implicated in controlling copper balance and cuproptosis. Besides, lncRNAs associated with cuproptosis pathway have demonstrated their potential as diagnostic and prognostic cancer biomarkers as well as indicators of treatment response. Our review aims to summarize recent studies focusing on the intricate relationship between lncRNAs and cuproptosis and explore the mechanisms by which lncRNAs can modulate copper homeostasis and regulate cuproptosis pathway. We also highlight recent discoveries concerning the role of cuproptosis-related lncRNAs in diagnosis, prognosis, and therapy of different types of cancer. By elucidating the significance of cuproptosis-related lncRNAs, this review provides insights into how these lncRNAs can be used to develop new therapeutic strategies to improve treatment outcomes.</div></div>","PeriodicalId":8174,"journal":{"name":"Archives of biochemistry and biophysics","volume":"765 ","pages":"Article 110324"},"PeriodicalIF":3.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143104586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we adopt an approach typical for PROteolysis Targeting Chimera (PROTAC), which is based on the artificial drawing together of the target protein to E3 ubiquitin ligase, to P-gp. Forced ubiquitinylation of a transmembrane protein will provoke its removal from the cell membrane and promote its subsequent degradation. Within this concept, we investigated the possibility of P-gp ubiquitinylation by a number of PROTAC-specific E3 ligases using several approaches. We also identified the most promising site for the development of P-gp ligands. By screening a diversified library of compounds, we not only identified a number of scaffolds suitable for the construction of specific ligands, but also proposed dorsomorphin as a convenient platform for creating the constituent of a bifunctional chimera. We show that dorsomorphin both has the structural characteristics necessary to develop a PROTAC-like molecule and exhibits P-gp inhibitory activity.
