Melanoma is the most aggressive form of skin cancer, characterized by a poor prognosis, and its incidence has risen rapidly over the past 30 years. Recent therapies, notably immunotherapy and targeted therapy, have significantly improved the outcome of patients with metastatic melanoma. Previously dismal five-year survival rates of below 5% have shifted to over 50% of patients surviving the five-year mark, marking a significant shift in the landscape of melanoma treatment and survival. Unfortunately, about 50% of patients either do not respond to therapy or experience early or late relapses following an initial response. The underlying mechanisms for primary and secondary resistance to targeted therapies or immunotherapy and relapse patterns remain not fully identified. However, several molecular pathways and genetic factors have been associated with melanoma resistance to these treatments. Understanding these mechanisms paves the way for creating novel treatments that can address resistance and ultimately enhance patient outcomes in melanoma. This review explores the mechanisms behind immunotherapy and targeted therapy resistance in melanoma patients. Additionally, it describes the treatment strategies to overcome resistance, which have improved patients' outcomes in clinical trials and practice.

黑色素瘤是最具侵袭性的皮肤癌,其特点是预后不良,在过去 30 年中发病率迅速上升。最近的疗法,尤其是免疫疗法和靶向疗法,大大改善了转移性黑色素瘤患者的预后。患者的五年生存率从以前的不足 5%,到现在的超过 50%,标志着黑色素瘤治疗和生存状况的重大转变。遗憾的是,约 50%的患者要么对治疗无反应,要么在初次反应后出现早期或晚期复发。靶向疗法或免疫疗法的原发性和继发性耐药性以及复发模式的基本机制仍未完全确定。不过,有几种分子途径和遗传因素与黑色素瘤对这些疗法的耐药性有关。了解这些机制可为创造新型治疗方法铺平道路,从而解决耐药性问题,并最终改善黑色素瘤患者的预后。本综述探讨了黑色素瘤患者对免疫疗法和靶向疗法产生耐药性的机制。此外,它还介绍了克服耐药性的治疗策略,这些策略在临床试验和实践中改善了患者的预后。

NFE2-like basic leucine zipper transcription factor 2 (NFE2L2, also known as NRF2), is a key transcription factor in the cellular defense against oxidative stress, playing a crucial role in cancer cell survival and resistance to therapies. This review outlines the current knowledge on the link between NFE2L2 and ferroptosis - a form of regulated cell death characterized by iron-dependent lipid peroxidation - within cancer cells. While NFE2L2 activation can protect normal cells from oxidative damage, its overexpression in cancer cells contributes to drug resistance by upregulating antioxidant defenses and inhibiting ferroptosis. We delve into the molecular pathways of ferroptosis, highlighting the involvement of NFE2L2 and its target genes, such as NQO1, HMOX1, FTH1, FTL, HERC2, SLC40A1, ABCB6, FECH, PIR, MT1G, SLC7A11, GCL, GSS, GSR, GPX4, AIFM2, MGST1, ALDH1A1, ALDH3A1, and G6PD, in ferroptosis resistance. Understanding the delicate balance between NFE2L2's protective and deleterious roles could pave the way for novel therapeutic strategies targeting NFE2L2 to enhance the efficacy of ferroptosis inducers in cancer therapy.

NFE2-like basic leucine zipper transcription factor 2(NFE2L2,又称 NRF2)是细胞防御氧化应激的关键转录因子,在癌细胞存活和抵抗疗法方面起着至关重要的作用。本综述概述了目前关于 NFE2L2 与铁中毒(一种以铁依赖性脂质过氧化为特征的调节性细胞死亡形式)之间联系的知识。NFE2L2的活化可以保护正常细胞免受氧化损伤,而它在癌细胞中的过度表达则会通过上调抗氧化防御功能和抑制铁氧化作用而导致耐药性。我们深入研究了铁氧化的分子途径,强调了 NFE2L2 及其靶基因(如 NQO1、HMOX1、FTH1、FTL、HERC2、SLC40A1、ABCB6、FECH、PIR、MT1G、SLC7A11、GCL、GSS、GSR、GPX4、AIFM2、MGST1、ALDH1A1、ALDH3A1 和 G6PD)在铁氧化耐药性中的参与。了解 NFE2L2 的保护作用和有害作用之间的微妙平衡,可以为针对 NFE2L2 的新型治疗策略铺平道路,从而提高铁变态反应诱导剂在癌症治疗中的疗效。

Aim: Cell division cycle 25B (CDC25B) belongs to the CDC25 family of phosphatases that regulate cell cycle progression. CDC25B also contributes to tumor initiation and progression, but no connection between CDC25B levels and drug sensitivity in pancreatic cancer has been reported. Based on our finding that bromodomain and extraterminal domain (BET) inhibitors decrease levels of CDC25B, we aim to compare the sensitivity of models expressing contrasting levels of CDC25B to the BET inhibitor JQ1, in pancreatic cancer cell lines in vitro and in patient-derived xenograft (PDX) models of pancreatic ductal adenocarcinoma (PDAC) in vivo. Methods: We compared the efficacy of the standard of care agent gemcitabine with the BET inhibitor JQ1, using alamarBlue assays to determine IC50s of three pancreatic cancer cell lines in vitro. We used immunohistochemistry (IHC) and immunoblot (IB) to detect CDC25B. We also compared the effect of each agent on the progression of PDX models of PDAC in vivo with contrasting levels of CDC25B. Results: Immunohistochemical data demonstrated that levels of CDC25B differed by ~2- to 5-fold in cell lines and PDX models used. In vitro data showed that the level of CDC25B paralleled sensitivity to JQ1. Similarly, in vivo data showed that tumors with high-level CDC25B were more sensitive to JQ1 than tumors with lower CDC25B. The combination of JQ1 + a pan CDC25 inhibitor was synergistic in gemcitabine-resistant Panc1.gemR cells that had relatively high levels of CDC25B expression compared to parent cells. Conclusion: The data suggest that CDC25B may be an independent indicator of sensitivity to BET inhibitors and that CDC25B may contribute to gemcitabine insensitivity in this tumor type.

目的:细胞分裂周期25B(CDC25B)属于调控细胞周期进展的CDC25磷酸酶家族。CDC25B 也有助于肿瘤的发生和发展,但目前还没有关于 CDC25B 水平与胰腺癌药物敏感性之间关系的报道。基于我们发现溴化结构域和外端结构域(BET)抑制剂会降低 CDC25B 的水平,我们旨在比较体外胰腺癌细胞系和体内胰腺导管腺癌(PDAC)患者来源异种移植(PDX)模型中表达不同水平 CDC25B 的模型对 BET 抑制剂 JQ1 的敏感性。方法:我们比较了标准治疗药物吉西他滨和 BET 抑制剂 JQ1 的疗效,使用氨溴索测定法确定了三种胰腺癌细胞系的体外 IC50。我们使用免疫组织化学(IHC)和免疫印迹(IB)检测 CDC25B。我们还比较了每种药物对体内具有不同 CDC25B 水平的 PDX PDAC 模型进展的影响。结果免疫组化数据显示,在所用的细胞系和 PDX 模型中,CDC25B 的水平相差约 2 到 5 倍。体外数据显示,CDC25B 的水平与对 JQ1 的敏感性相关。同样,体内数据显示,CDC25B水平高的肿瘤比CDC25B水平低的肿瘤对JQ1更敏感。与母细胞相比,CDC25B表达水平相对较高的抗吉西他滨的Panc1.gemR细胞中,JQ1+泛CDC25抑制剂的组合具有协同作用。结论这些数据表明,CDC25B 可能是 BET 抑制剂敏感性的一个独立指标,而且 CDC25B 可能是该肿瘤类型对吉西他滨不敏感的原因之一。

Ovarian cancer is a significant global health challenge, with cytoreductive surgery and platinum-based chemotherapy serving as established primary treatments. Unfortunately, most patients relapse and ultimately become platinum-resistant, at which point there are limited effective treatment options. Given the success of immunotherapy in inducing durable treatment responses in several other cancers, its potential in platinum-resistant ovarian cancer (PROC) is currently being investigated. However, in unselected advanced ovarian cancer populations, researchers have reported low response rates to immune checkpoint inhibition, and thus far, no validated biomarkers are predictive of response. Understanding the intricate interplay between platinum resistance, immune recognition, and the tumour microenvironment (TME) is crucial. In this review, we examine the research challenges encountered thus far, the biological rationale for immunotherapy, the underlying mechanisms of immune resistance, and new strategies to overcome resistance.

卵巢癌是全球健康面临的重大挑战,细胞修复手术和铂类化疗是公认的主要治疗方法。遗憾的是,大多数患者会复发并最终对铂类药物产生耐药性,此时有效的治疗方案十分有限。鉴于免疫疗法在诱导其他几种癌症的持久治疗反应方面取得了成功,目前正在研究其在铂类耐药卵巢癌(PROC)中的潜力。然而,在未经选择的晚期卵巢癌人群中,研究人员发现免疫检查点抑制的反应率很低,而且到目前为止,还没有有效的生物标志物可以预测反应。了解铂耐药性、免疫识别和肿瘤微环境(TME)之间错综复杂的相互作用至关重要。在这篇综述中,我们将探讨迄今为止所遇到的研究挑战、免疫疗法的生物学原理、免疫耐受的内在机制以及克服耐药性的新策略。

Studies of carcinogenic metabolism have shown that cancer cells have significant metabolic adaptability and that their metabolic dynamics undergo extensive reprogramming, which is a fundamental feature of cancer. The Warburg effect describes the preference of cancer cells for glycolysis over oxidative phosphorylation (OXPHOS), even under aerobic conditions. However, metabolic reprogramming in cancer cells involves not only glycolysis but also changes in lipid and amino acid metabolism. The mechanisms of these metabolic shifts are critical for the discovery of novel cancer therapeutic targets. Despite advances in the field of oncology, chemotherapy resistance, including multidrug resistance, remains a challenge. Research has revealed a correlation between metabolic reprogramming and anticancer drug resistance, but the underlying complex mechanisms are not fully understood. In addition, small extracellular vesicles (sEVs) may play a role in expanding metabolic reprogramming and promoting the development of drug resistance by mediating intercellular communication. The aim of this review is to assess the metabolic reprogramming processes that intersect with resistance to anticancer therapy, with particular attention given to the changes in glycolysis, lipid metabolism, and amino acid metabolism that accompany this phenomenon. In addition, the role of sEVs in disseminating metabolic reprogramming and promoting the development of drug-resistant phenotypes will be critically evaluated.

对致癌新陈代谢的研究表明,癌细胞具有很强的新陈代谢适应能力,其新陈代谢动态会发生广泛的重编程,这是癌症的一个基本特征。沃伯格效应描述了癌细胞对糖酵解的偏好,而不是氧化磷酸化(OXPHOS),即使在有氧条件下也是如此。然而,癌细胞的代谢重编程不仅涉及糖酵解,还包括脂质和氨基酸代谢的变化。这些代谢转变的机制对于发现新型癌症治疗靶点至关重要。尽管肿瘤学领域取得了进展,但化疗耐药性(包括多药耐药性)仍是一项挑战。研究发现,代谢重编程与抗癌药物耐药性之间存在相关性,但其背后的复杂机制尚未完全明了。此外,细胞外小泡(sEVs)可能通过介导细胞间通讯,在扩大代谢重编程和促进耐药性发展方面发挥作用。本综述旨在评估与抗癌治疗耐药性交织在一起的代谢重编程过程,尤其关注伴随这一现象出现的糖酵解、脂质代谢和氨基酸代谢的变化。此外,还将严格评估 sEV 在传播代谢重编程和促进耐药表型发展方面的作用。

Competing endogenous RNAs (ceRNAs) are transcripts that possess highly similar microRNA response elements (MREs). microRNAs (miRNAs) are short, endogenous, single-stranded non-coding RNAs (ncRNAs) that can repress gene expression by binding to MREs on the 3' untranslated regions (UTRs) of the target mRNA transcripts to suppress gene expression by promoting mRNA degradation and/or inhibiting protein translation. mRNA transcripts, circular RNAs (circRNAs), long non-coding RNAs (lncRNAs), and transcribed pseudogenes could share similar MREs, and they can compete for the same pool of miRNAs. These ceRNAs may affect the level of one another by competing for their shared miRNAs. This interplay between different RNAs constitutes a ceRNA network, which regulates many important biological processes. Cancer drug resistance is a major factor leading to treatment failure in patients receiving chemotherapy. It can be acquired through genetic, epigenetic, and various tumor microenvironment mechanisms. The involvement of ceRNA crosstalk and its disruption in chemotherapy resistance is attracting attention in the cancer research community. This review presents an updated summary of the latest research on ceRNA dysregulation causing drug resistance across different cancer types and chemotherapeutic drug classes. Interestingly, accumulating evidence suggests that ceRNAs may be used as prognostic biomarkers to predict clinical response to cancer chemotherapy. Nevertheless, detailed experimental investigations of the putative ceRNA networks generated by computational algorithms are needed to support their translation for therapeutic and prognostic applications.

竞争性内源性 RNA(ceRNA)是指具有高度相似的 microRNA 响应元件(MRE)的转录本。microRNA(miRNA)是短的内源性单链非编码 RNA(ncRNA),可通过与目标 mRNA 转录本 3' 非翻译区(UTR)上的 MRE 结合抑制基因表达,从而通过促进 mRNA 降解和/或抑制蛋白质翻译来抑制基因表达。mRNA 转录本、环状 RNA(circRNA)、长非编码 RNA(lncRNA)和转录假基因可能共享相似的 MREs,它们可以竞争同一个 miRNA 池。这些 ceRNA 可通过竞争共享的 miRNA 而影响彼此的水平。不同 RNA 之间的这种相互作用构成了一个 ceRNA 网络,它调控着许多重要的生物过程。癌症耐药性是导致化疗患者治疗失败的一个主要因素。耐药性可通过遗传、表观遗传和各种肿瘤微环境机制获得。ceRNA串联及其在化疗耐药性中的作用正引起癌症研究界的关注。本综述对不同癌症类型和化疗药物类别中导致耐药性的 ceRNA 失调的最新研究进行了总结。有趣的是,越来越多的证据表明,ceRNA 可作为预后生物标志物来预测癌症化疗的临床反应。不过,还需要对计算算法生成的假定 ceRNA 网络进行详细的实验研究,以支持其在治疗和预后方面的应用。

Aim: ATP-binding cassette (ABC) transporters are proteins responsible for the efflux of drug molecules from cancer cells, reducing the efficacy of anti-cancer treatments. This study assesses the susceptibility of a panel of clinically used photosensitizers to be transported by ABC transporters in vitro. Methods: The involvement of P-glycoprotein (P-gp/ABCB1), breast cancer resistance protein (BCRP/ABCG2), and multidrug resistance-associated protein 1 (MRP1/ABCC1) in the transport of 7 clinically utilized photosensitizers [benzoporphyrin derivative (BPD), temoporfin, redaporfin, talaporfin sodium, rose bengal, methylene blue, and indocyanine green] were investigated using human breast cancer cell lines following well-established protocols. Briefly, parental MCF-7 cells and sublines that overexpress P-gp (MCF-7 TX400), ABCG2 (MCF-7 MX100), or MRP1 (MCF-7/VP) were treated with photosensitizers with and without ABC transporter inhibitors. Intracellular levels of photosensitizers were measured using extraction method and flow cytometry to determine whether the ABC transporters are associated with efflux or uptake of photosensitizers. Results: The ABCG2 inhibitor (fumitremorgin C) and P-gp inhibitor (valspodar) effectively blocked the transport mediated by ABCG2 and P-gp of rose bengal and BPD. Redaporfin showed increased accumulation in the presence of valspodar with flow cytometry. Interestingly, MCF-7/VP cells were found to have reduced intracellular accumulation of rose bengal, which was restored with MRP1 inhibitor (MK571). The cell viability assay showed photodynamic therapy (PDT) resistance with Redaporfin in P-gp-overexpressing cells, BPD in ABCG2- and P-gp-overexpressing cells, and with Rose bengal in ABCG2-, P-gp- and MRP1-overexpressing cells, respectively. However, no change in intracellular retention was observed for other photosensitizers. Conclusion: In summary, our study provided new knowledge that temoporfin, talaporfin sodium, methylene blue, and indocyanine green are not substrates of ABCG2, P-gp, or MRP1. Redaporfin is a substrate for P-gp. BPD is a known substrate of ABCG2 and P-gp. Rose bengal is a substrate of ABCG2, P-gp, and MRP1. The results presented here indicate ABC transporter substrate status as a possible cause for cellular resistance to photodynamic therapy with rose bengal, redaporfin, and BPD.

目的:ATP 结合盒(ABC)转运体是一种蛋白质,负责将药物分子从癌细胞中排出,从而降低抗癌治疗的疗效。本研究评估了一组临床使用的光敏剂在体外被 ABC 转运体转运的敏感性。方法:采用人乳腺癌细胞系,按照成熟的方案研究了 P-糖蛋白(P-gp/ABCB1)、乳腺癌抗性蛋白(BCRP/ABCG2)和多药耐药性相关蛋白 1(MRP1/ABCC1)参与 7 种临床常用光敏剂[苯并卟啉衍生物(BPD)、替莫卟吩、瑞达泊芬、他拉泊芬钠、玫瑰红、亚甲蓝和吲哚菁绿]转运的情况。简而言之,亲代 MCF-7 细胞和过表达 P-gp(MCF-7 TX400)、ABCG2(MCF-7 MX100)或 MRP1(MCF-7/VP)的亚系细胞在使用或不使用 ABC 转运体抑制剂的情况下用光敏剂处理。使用萃取法和流式细胞术测量细胞内光敏剂的水平,以确定 ABC 转运体是否与光敏剂的外流或吸收有关。结果ABCG2抑制剂(fumitremorgin C)和P-gp抑制剂(valspodar)能有效阻断玫瑰红和BPD在ABCG2和P-gp介导下的转运。流式细胞术显示,在 valspodar 的存在下,Redaporfin 的积累增加。有趣的是,MCF-7/VP 细胞发现玫瑰红素在细胞内的蓄积减少了,而使用 MRP1 抑制剂(MK571)后又恢复了。细胞活力测定显示,P-gp 基因过表达细胞对 Redaporfin 的光动力疗法(PDT)耐药,ABCG2-和 P-gp 基因过表达细胞对 BPD 的光动力疗法耐药,ABCG2-、P-gp-和 MRP1 基因过表达细胞对玫瑰红的光动力疗法耐药。然而,其他光敏剂在细胞内的保留时间没有变化。结论总之,我们的研究提供了新的知识,即替莫泊芬、他拉泊芬钠、亚甲基蓝和吲哚菁绿不是 ABCG2、P-gp 或 MRP1 的底物。雷达波芬是 P-gp 的底物。BPD 是 ABCG2 和 P-gp 的已知底物。玫瑰红是 ABCG2、P-gp 和 MRP1 的底物。本文的研究结果表明,ABC 转运体底物状态可能是导致细胞对玫瑰红、redaporfin 和 BPD 光动力疗法产生耐药性的原因之一。

Multidrug resistance (MDR) poses a formidable obstacle in cancer treatment, enabling cancer cells to evade the cytotoxic effects of chemotherapeutic drugs through various mechanisms. These mechanisms include intrinsic resistance, which is present prior to treatment, and acquired resistance, which develops after exposure to chemotherapy agents. Small membrane-bound vesicles, known as extracellular vesicles (EVs), are crucial in intercellular signaling as they transport bioactive molecules that can modify the characteristics and functions of recipient cells. Recent research highlights EVs as pivotal players in fostering drug resistance. This review focuses on the intercellular transfer of MDR from donor cells to susceptible recipient cells through specific cargo in EVs, such as ATP-binding cassette (ABC) transporter proteins, nucleic acids, and other regulatory factors. Additionally, the features of intercellular communication mediated by EVs are also discussed. Gaining insight into these mechanisms is essential for developing strategies to counteract resistance and improve the effectiveness of cancer treatments.

多药耐药性(MDR)是癌症治疗中的一个巨大障碍,它使癌细胞能够通过各种机制逃避化疗药物的细胞毒性作用。这些机制包括治疗前就存在的内在耐药性和接触化疗药物后产生的获得性耐药性。被称为细胞外囊泡(EVs)的膜结合小囊泡在细胞间信号传递中至关重要,因为它们运输的生物活性分子可以改变受体细胞的特性和功能。最近的研究强调,EVs 是产生耐药性的关键因素。本综述重点探讨了 MDR 通过 EV 中的特定货物(如 ATP 结合盒 (ABC) 转运蛋白、核酸和其他调节因子)从供体细胞向易感受体细胞的细胞间转移。此外,还讨论了由 EVs 介导的细胞间通信的特点。深入了解这些机制对于开发抗药性策略和提高癌症治疗效果至关重要。

Head and neck cancer (HNC) is ranked as the sixth most common malignant tumor, and the overall survival rate with current treatment options remains concerning, primarily due to drug resistance that develops following antitumor therapy. Recent studies indicate that non-coding RNAs play a crucial role in drug resistance among HNC patients. This article systematically reviews the current research landscape, explores novel targets and treatment strategies related to non-coding RNAs and HNC resistance, raises some unresolved issues, and discusses five promising research directions in this field: ferroptosis, nanomedicine, exosomes, proteolysis-targeting chimeras (PROTACs), and artificial intelligence. We hope that our work will contribute to advancing research on overcoming HNC resistance through the regulation of non-coding RNAs.

头颈癌(HNC)被列为第六大常见恶性肿瘤,目前的治疗方案的总体生存率仍然令人担忧,这主要是由于抗肿瘤治疗后产生的耐药性。最近的研究表明,非编码 RNA 在 HNC 患者的耐药性中起着至关重要的作用。本文系统回顾了当前的研究现状,探讨了与非编码 RNA 和 HNC 耐药性相关的新靶点和治疗策略,提出了一些尚未解决的问题,并讨论了该领域五个前景广阔的研究方向:铁肽化、纳米药物、外泌体、蛋白酶靶向嵌合体 (PROTAC) 和人工智能。我们希望我们的工作将有助于推动通过调控非编码 RNA 克服 HNC 抗性的研究。

Breast cancer is one of the most common cancers in women globally, posing significant challenges to treatment because of the diverse and complex pathological and molecular subtypes. The emergence of immune checkpoint inhibitors (ICIs) has revolutionized the treatment of breast cancer, particularly for triple-negative breast cancer (TNBC), significantly improving patient outcomes. However, the overall tumor response rate remains suboptimal due to drug resistance to ICIs. This resistance is primarily due to the immune-suppressive tumor microenvironment (TME), tumor cells' ability to evade immune surveillance, and other complex immune regulatory mechanisms. To address these challenges, clinical researchers are actively exploring combinatorial therapeutic strategies with ICIs. Tumor local ablation (TLA) technology is anticipated to overcome resistance to ICIs and enhance therapeutic efficacy by ablating tumor tissue, releasing tumor antigens, remodeling the TME, and stimulating local and systemic immune responses. Combination therapy with TLA and ICIs has demonstrated promising results in preclinical breast cancer studies, underscoring the feasibility and importance of addressing drug resistance mechanisms in breast cancer. This provides novel strategies for breast cancer treatment and is expected to drive further advancements in the field.

乳腺癌是全球妇女最常见的癌症之一,由于其病理和分子亚型的多样性和复杂性,给治疗带来了巨大挑战。免疫检查点抑制剂(ICIs)的出现彻底改变了乳腺癌的治疗,尤其是三阴性乳腺癌(TNBC)的治疗,显著改善了患者的预后。然而,由于对 ICIs 的耐药性,总体肿瘤反应率仍不理想。这种耐药性主要是由于免疫抑制性肿瘤微环境(TME)、肿瘤细胞逃避免疫监视的能力以及其他复杂的免疫调节机制造成的。为了应对这些挑战,临床研究人员正在积极探索 ICIs 的组合治疗策略。肿瘤局部消融(TLA)技术有望通过消融肿瘤组织、释放肿瘤抗原、重塑 TME 以及刺激局部和全身免疫反应来克服 ICIs 的抗药性并提高疗效。在乳腺癌临床前研究中,TLA 与 ICIs 的联合疗法取得了令人鼓舞的结果,突出了解决乳腺癌耐药机制的可行性和重要性。这为乳腺癌治疗提供了新策略,有望推动该领域的进一步发展。
