Undifferentiated pleomorphic sarcomas (UPS) represent a prevalent and aggressive subtype of soft tissue sarcomas (STS) in adults. Despite advancements in loco regional treatments, many patients with high grade STS, including UPS, develop metastatic disease. Neoadjuvant chemotherapy is a standard approach to mitigate this risk, but response variability necessitates refined patient selection strategies. This study investigated the correlation between UPS microenvironment and neoadjuvant chemotherapy response in resectable UPS. The NEOSARCOMICS study (NCT02789384) enrolled patients with resectable STS from six sarcoma centers in France. Patients received anthracycline based chemotherapy, followed by surgery. Histological response, gene expression profiling, and multiplex immunohistofluorescence were performed on baseline and post treatment tumor samples. Plasma proteomics was analyzed to identify biomarkers. Good responders to neoadjuvant chemotherapy showed enrichment in genes related to stemness and cell cycle regulation, while poor responders exhibited immune related gene enrichment. Proteomic profiling revealed immune pathway activation and downregulation of cell cycle pathways in non responders. Despite being associated with a good prognosis, high immune infiltration, particularly of CD8 + T cells and CD20 + B cells, predicts a poor response to neoadjuvant chemotherapy in UPS, suggesting the need for alternative therapeutic strategies for patients with inflamed UPS.Ongoing clinical trials are exploring the efficacy of combining chemotherapy with immune checkpoint inhibitors to improve outcomes.
未分化多形性肉瘤(UPS)是成人软组织肉瘤(STS)中一种常见的侵袭性亚型。尽管局部区域治疗取得了进展,但包括 UPS 在内的许多高级别 STS 患者仍会出现转移性疾病。新辅助化疗是降低这一风险的标准方法,但反应的多变性要求对患者的选择策略进行改进。本研究调查了可切除UPS微环境与新辅助化疗反应之间的相关性。NEOSARCOMICS研究(NCT02789384)招募了来自法国六个肉瘤中心的可切除STS患者。患者接受蒽环类化疗,然后进行手术。对基线和治疗后的肿瘤样本进行了组织学反应、基因表达谱分析和多重免疫组化荧光分析。对血浆蛋白质组学进行了分析,以确定生物标志物。对新辅助化疗反应良好者的干性和细胞周期调控相关基因富集,而反应不佳者的免疫相关基因富集。蛋白质组分析表明,免疫通路被激活,而无应答者的细胞周期通路下调。尽管预后良好,但高免疫浸润,尤其是CD8 + T细胞和CD20 + B细胞的浸润,预示着UPS患者对新辅助化疗的反应不佳,这表明有必要为有炎症的UPS患者制定替代治疗策略。

Accurate and up-to-date estimates of the global cancer burden in adolescents and young adults (AYA) are scarce. This study aims to assess the global burden and trends of AYA cancer, with a focus on socioeconomic disparities, to inform global cancer control strategies. AYA cancer, defined as cancer occurring in individuals aged 15–39, was analyzed using data from the Global Burden of Disease (GBD) 2021 study and the Global Cancer Observatory (GLOBOCAN) 2022 project. We examined the global burden by age, sex, geographic location, and Human Development Index (HDI), as well as its temporal trends. Primary outcomes included age-standardized incidence and mortality rates (ASIR, ASMR) and the average annual percent change (AAPC). In 2022, an estimated 1,300,196 incidental cases and 377,621 cancer-related deaths occurred among AYAs worldwide, with an ASIR of 40.3 per 100,000 and an ASMR of 11.8 per 100,000. The most common cancers were breast, thyroid, and cervical, while the leading causes of death were breast, cervical, and leukemia. The incidence and mortality were disproportionately higher among females (ASIR: 52.9 for females vs. 28.3 for males; ASMR: 13.1 for females vs. 10.6 for males). Countries with higher HDI experienced a higher incidence of AYA cancers (ASIR: 32.0 [low HDI] vs. 54.8 [very high HDI]), while countries with lower HDI faced a disproportionately higher mortality burden (ASMR: 17.2 [low HDI] vs. 8.4 [very high HDI]) despite their relatively low incidence. Disproportionality and regression measures highlighted significant HDI-related inequalities. AYA cancer incidence was stable from 2000 to 2011 (AAPC: − 0.04) but increased from 2012 to 2021 (AAPC: 0.53), driven by growing gonadal and colorectal cancers. Mortality decreased substantially from 2000 to 2011 (AAPC: − 1.64), but the decline slowed from 2012 (AAPC: − 0.32) probably due to increased deaths from gonadal cancers. These trends varied by sex, cancer type, geography, and HDI. AYA cancers present a significant and growing global burden, with marked disparities across sex, geographic locations, and HDI levels. Policymakers should prioritize equitable resource allocation and implement targeted interventions to reduce these inequalities, particularly in low-HDI regions and with regard to gonadal cancers.
对全球青少年和年轻成人(AYA)癌症负担的最新准确估算还很少。本研究旨在评估全球青少年癌症负担和趋势,重点关注社会经济差异,为全球癌症控制策略提供参考。青少年癌症是指发生在 15-39 岁人群中的癌症,本研究利用 2021 年全球疾病负担(GBD)研究和 2022 年全球癌症观察站(GLOBOCAN)项目的数据对青少年癌症进行了分析。我们研究了按年龄、性别、地理位置和人类发展指数(HDI)划分的全球负担及其时间趋势。主要结果包括年龄标准化发病率和死亡率(ASIR、ASMR)以及年均百分比变化(AAPC)。2022 年,全球青少年中估计有 1,300,196 例偶发病例和 377,621 例癌症相关死亡病例,年龄标准化发病率为每 10 万人 40.3 例,年龄标准化死亡率为每 10 万人 11.8 例。最常见的癌症是乳腺癌、甲状腺癌和宫颈癌,而主要死因是乳腺癌、宫颈癌和白血病。女性的发病率和死亡率高得不成比例(ASIR:女性 52.9 例,男性 28.3 例;ASMR:女性 13.1 例,男性 10.6 例)。在人类发展指数较高的国家,青少年癌症的发病率较高(ASIR:32.0[低人类发展指数] vs. 54.8[极高人类发展指数]),而在人类发展指数较低的国家,尽管发病率相对较低,但死亡率却高得不成比例(ASMR:17.2[低人类发展指数] vs. 8.4[极高人类发展指数])。比例失调和回归测量凸显了与人类发展指数相关的严重不平等。2000 年至 2011 年,亚裔青少年癌症发病率保持稳定(亚裔青少年癌症发病率:- 0.04),但 2012 年至 2021 年,受性腺癌和结肠直肠癌增加的影响,发病率有所上升(亚裔青少年癌症发病率:0.53)。2000 年至 2011 年,死亡率大幅下降(美国癌症协会:- 1.64),但从 2012 年开始下降速度放缓(美国癌症协会:- 0.32),这可能是由于性腺癌症导致的死亡人数增加。这些趋势因性别、癌症类型、地域和人类发展指数而异。青壮年癌症给全球带来了巨大且不断增长的负担,不同性别、不同地理位置和不同人类发展指数水平之间存在明显差异。政策制定者应优先考虑公平的资源分配,并实施有针对性的干预措施,以减少这些不平等现象,尤其是在低人类发展指数地区和性腺癌症方面。

In recent years, cell therapy research and commercialization have significantly accelerated, especially after the US FDA approved CAR-T therapy. While cell therapy now leads immuno-oncology in clinical trials, challenges such as redundant R&D, target clustering, and unmet clinical need remain. Since 2017, China has established a dual-track regulatory framework, facilitating rapid growth in its cell therapy pipeline, making it the second largest in the world. Despite this progress, China faces similar global challenges. Our study covers 2,794 registered cell therapy clinical trials in China, including 2,045 for immune cell, 683 for stem cell, and 66 for other somatic cell. It compares cell therapy products approved in China, the US, EU, and Japan, analyzes the evolving clinical trials landscape, and highlights the characteristics of investigator-initiated trials (IITs) and industry-sponsored trials (ISTs) in China. Our findings indicate that despite the high disease burden and unmet clinical needs for solid tumors in China, over 38% of trials between 2021 and 2023 focused on hematologic malignancies with established targets like CD19 and BCMA. Over 90% of trials are IITs, which show notable clinical differences from ISTs. We recommend that Chinese regulators establish specific guidelines to promote clinical-value-driven research. Stricter regulatory standards should also be implemented to minimize redundant R&D. Additionally, a value-based reimbursement system for within-class targeted cell therapy products may further reduce duplicated R&D efforts. Given the prevalence of IITs, specifying requirements for IITs could create a new pathway to accelerate product development and better address unmet clinical needs in China.
近年来,细胞疗法的研究和商业化进程明显加快,尤其是在美国 FDA 批准 CAR-T 疗法之后。虽然细胞疗法目前在临床试验中领先于免疫肿瘤学,但冗余研发、靶点集群和未满足临床需求等挑战依然存在。自 2017 年以来,中国建立了双轨监管框架,促进了细胞疗法管线的快速增长,使其成为全球第二大细胞疗法管线。尽管取得了这一进展,但中国也面临着类似的全球性挑战。我们的研究涵盖了 2794 项在中国注册的细胞疗法临床试验,其中包括 2045 项免疫细胞临床试验、683 项干细胞临床试验和 66 项其他体细胞临床试验。它比较了中国、美国、欧盟和日本批准的细胞治疗产品,分析了不断变化的临床试验格局,并突出了中国研究者发起的试验(IIT)和行业赞助的试验(IST)的特点。我们的研究结果表明,尽管中国实体瘤的疾病负担较重,临床需求尚未得到满足,但在2021年至2023年期间,超过38%的试验集中于血液系统恶性肿瘤,其靶点已确立,如CD19和BCMA。90%以上的试验是IITs,与ISTs有明显的临床差异。我们建议中国监管机构制定具体指南,促进临床价值驱动型研究。还应实施更严格的监管标准,尽量减少重复研发。此外,对同类靶向细胞治疗产品实行基于价值的报销制度,可进一步减少重复研发工作。考虑到 IIT 的普遍性,明确规定 IIT 的要求可为加快产品开发和更好地满足中国尚未满足的临床需求开辟一条新途径。

Tumor cells develop multiple mechanisms to facilitate their immune evasion. Identifying tumor-intrinsic factors that support immune evasion may provide new strategies for cancer immunotherapy. We aimed to explore the function and the mechanism of the tumor-intrinsic factor NPM1, a multifunctional nucleolar phosphoprotein, in cancer immune evasion and progression. The roles of NPM1 in tumor progression and tumor microenvironment (TME) reprogramming were examined by subcutaneous inoculation of Npm1-deficient tumor cells into syngeneic mice, and then explored by CyTOF, flow cytometry, immunohistochemistry staining, and RNA-seq. The in-vitro T-cell killing of OVA-presenting tumor cells by OT-1 transgenic T cells was observed. The interaction of NPM1 and IRF1 was verified by Co-IP. The regulation of NPM1 in IRF1 DNA binding to Nlrc5, Ciita promoter was determined by dual-luciferase reporter assay and ChIP-qPCR. High levels of NPM1 expression predict low survival rates in various human tumors. Loss of NPM1 inhibited tumor progression and enhanced the survival of tumor-bearing mice. Npm1-deficient tumors showed increased CD8+ T cell infiltration and activation alongside the reduced presence of immunosuppressive cells. Npm1 deficiency increased MHC-I and MHC-II molecules and specific T-cell killing. Mechanistically, NPM1 associates with the transcription factor IRF1 and then sequesters IRF1 from binding to the Nlrc5 and Ciita promoters to suppress IRF1-mediated expression of MHC-I and MHC-II molecules in tumor cells. Tumor-intrinsic NPM1 promotes tumor immune evasion via suppressing IRF1-mediated antigen presentation to impair tumor immunogenicity and reprogram the immunosuppressive TME. Our study identifies NPM1 as a potential target for improving cancer immunotherapy.
肿瘤细胞发展出多种机制来促进其免疫逃避。识别支持免疫逃避的肿瘤内在因子可为癌症免疫治疗提供新策略。我们旨在探索肿瘤内在因子NPM1(一种多功能核磷蛋白)在肿瘤免疫逃避和进展中的功能和机制。通过将NPM1缺陷的肿瘤细胞皮下接种到合成小鼠体内,然后通过CyTOF、流式细胞术、免疫组化染色和RNA-seq等方法探讨了NPM1在肿瘤进展和肿瘤微环境(TME)重编程中的作用。实验观察了 OT-1 转基因 T 细胞在体外对呈递 OVA 的肿瘤细胞的杀伤作用。通过Co-IP验证了NPM1和IRF1的相互作用。通过双荧光素酶报告实验和 ChIP-qPCR 测定了 NPM1 对 IRF1 DNA 与 Nlrc5、Ciita 启动子结合的调控作用。NPM1的高水平表达预示着各种人类肿瘤的低存活率。缺失 NPM1 可抑制肿瘤进展并提高肿瘤小鼠的存活率。缺失 Npm1 的肿瘤显示 CD8+ T 细胞浸润和活化增加,同时免疫抑制细胞减少。Npm1缺陷增加了MHC-I和MHC-II分子以及特异性T细胞杀伤力。从机理上讲,NPM1 与转录因子 IRF1 结合,然后阻止 IRF1 与 Nlrc5 和 Ciita 启动子结合,从而抑制 IRF1 介导的肿瘤细胞中 MHC-I 和 MHC-II 分子的表达。肿瘤内在 NPM1 通过抑制 IRF1 介导的抗原递呈来损害肿瘤的免疫原性,并对免疫抑制性 TME 进行重编程,从而促进肿瘤免疫逃避。我们的研究将 NPM1 确定为改善癌症免疫疗法的潜在靶点。

Due to spatial and genomic independence, mitochondria possess a translational mechanism distinct from that of cytoplasmic translation. Several regulators participate in the modulation of mitochondrial translation. Mitochondrial translation is coordinated with cytoplasmic translation through stress responses. Importantly, the inhibition of mitochondrial translation leads to the inhibition of cytoplasmic translation and metabolic disruption. Therefore, defects in mitochondrial translation are closely related to the functions of hematopoietic cells and various immune cells. Finally, the inhibition of mitochondrial translation is a potential therapeutic target for treating multiple hematologic malignancies. Collectively, more in-depth insights into mitochondrial translation not only facilitate our understanding of its functions in hematopoiesis, but also provide a basis for the discovery of new treatments for hematological malignancies and the modulation of immune cell function.
由于空间和基因组的独立性,线粒体具有不同于细胞质翻译的翻译机制。有几种调节因子参与线粒体翻译的调节。通过应激反应,线粒体翻译与细胞质翻译相互协调。重要的是,抑制线粒体翻译会导致抑制细胞质翻译和新陈代谢紊乱。因此,线粒体翻译缺陷与造血细胞和各种免疫细胞的功能密切相关。最后,抑制线粒体翻译是治疗多种血液恶性肿瘤的潜在治疗靶点。总之,对线粒体翻译的深入研究不仅有助于我们了解线粒体在造血过程中的功能,还为发现治疗血液恶性肿瘤和调节免疫细胞功能的新疗法提供了基础。

Letermovir (LTV) prophylaxis is effective in reducing the incidence of clinically significant cytomegalovirus (CMV) infection (cs CMVi) after allogeneic haematopoietic stem cell transplantation (allo-HSCT). Since our centre began administering LTV prophylaxis in June 2022, we have observed a certain increase in the incidence of Epstein–Barr virus (EBV) reactivation after haploidentical HSCT. We retrospectively analysed 230 consecutive patients who underwent haploidentical HSCT with rabbit anti-thymocyte globulin (ATG) from October 2022 to June 2023. The LTV group included 133 patients who received LTV prophylaxis, and the control group included 97 patients who did not receive LTV prophylaxis. At 1 year after HSCT, EBV reactivation was observed in 36 patients (27%) in the LTV group and 13 patients (13%) in the control group (p = 0.012). All patients with EBV reactivation had EBV-DNAemia, and one patient in each group developed EBV-associated posttransplantation lymphoproliferative disorder (PTLD). The proportion of patients with low EBV-DNA loads (> 5 × 102 to < 1 × 104 copies/mL) was greater in the LTV group than in the control group (23% vs. 10%, p = 0.01). The proportion of patients with CMV reactivation was lower in the LTV group than in the control group (35% vs. 56%, p = 0.002). There was no significant difference between the groups in terms of neutrophil and platelet count recovery, the cumulative incidence of acute/chronic graft-versus-host disease, overall survival, cumulative relapse rate or nonrelapse mortality. Our results show that the increased incidence of EBV reactivation may be associated with LTV prophylaxis for CMV after haploidentical HSCT.
来替莫韦(LTV)预防性治疗可有效降低异基因造血干细胞移植(allo-HSCT)后临床重大巨细胞病毒(CMV)感染(cs CMVi)的发生率。自本中心于2022年6月开始实施LTV预防措施以来,我们观察到单倍体造血干细胞移植后爱泼斯坦-巴氏病毒(EBV)再活化的发生率有了一定程度的增加。我们回顾性分析了2022年10月至2023年6月期间连续接受兔抗胸腺细胞球蛋白(ATG)单倍体造血干细胞移植的230例患者。LTV组包括133名接受LTV预防治疗的患者,对照组包括97名未接受LTV预防治疗的患者。造血干细胞移植后 1 年,LTV 组有 36 名患者(27%)观察到 EBV 再激活,对照组有 13 名患者(13%)观察到 EBV 再激活(P = 0.012)。所有EBV再活化患者都患有EBV-DNA血症,每组各有一名患者出现EBV相关的移植后淋巴组织增生性疾病(PTLD)。低EBV-DNA载量(> 5 × 102 至 < 1 × 104拷贝/毫升)患者的比例在LTV组高于对照组(23% 对 10%,P = 0.01)。LTV组的CMV再激活患者比例低于对照组(35% 对 56%,P = 0.002)。在中性粒细胞和血小板计数恢复、急性/慢性移植物抗宿主病累积发病率、总生存率、累积复发率或非复发死亡率方面,两组间无明显差异。我们的研究结果表明,EBV再激活发生率的增加可能与单倍体造血干细胞移植后对CMV进行LTV预防有关。

Pancreatic cancer remains one of the most aggressive solid tumors. As a systemic disease, despite the improvement of multi-modality treatment strategies, the prognosis of pancreatic cancer was not improved dramatically. For resectable or borderline resectable patients, the surgical strategy centered on improving R0 resection rate is consensus; however, the role of neoadjuvant therapy in resectable patients and the optimal neoadjuvant therapy of chemotherapy with or without radiotherapy in borderline resectable patients were debated. Postoperative adjuvant chemotherapy of gemcitabine/capecitabine or mFOLFIRINOX is recommended regardless of the margin status. Chemotherapy as the first-line treatment strategy for advanced or metastatic patients included FOLFIRINOX, gemcitabine/nab-paclitaxel, or NALIRIFOX regimens whereas 5-FU plus liposomal irinotecan was the only standard of care second-line therapy. Immunotherapy is an innovative therapy although anti-PD-1 antibody is currently the only agent approved by for MSI-H, dMMR, or TMB-high solid tumors, which represent a very small subset of pancreatic cancers. Combination strategies to increase the immunogenicity and to overcome the immunosuppressive tumor microenvironment may sensitize pancreatic cancer to immunotherapy. Targeted therapies represented by PARP and KRAS inhibitors are also under investigation, showing benefits in improving progression-free survival and objective response rate. This review discusses the current treatment modalities and highlights innovative therapies for pancreatic cancer.

胰腺癌仍然是侵袭性最强的实体肿瘤之一。作为一种全身性疾病,尽管多模式治疗策略不断改进,但胰腺癌的预后并未得到显著改善。对于可切除或边缘可切除患者,以提高 R0 切除率为中心的手术策略已成为共识;然而,新辅助治疗在可切除患者中的作用,以及化疗联合或不联合放疗的最佳新辅助治疗在边缘可切除患者中的作用却存在争议。无论边缘状态如何,均建议术后辅助化疗吉西他滨/卡培他滨或 mFOLFIRINOX。化疗作为晚期或转移性患者的一线治疗策略,包括FOLFIRINOX、吉西他滨/纳布紫杉醇或NALIRIFOX方案,而5-FU加脂质体伊立替康是唯一的二线标准疗法。免疫疗法是一种创新疗法,尽管抗PD-1抗体是目前唯一获准用于MSI-H、dMMR或TMB-高实体瘤的药物,而这些肿瘤只占胰腺癌的极小一部分。增加免疫原性和克服免疫抑制性肿瘤微环境的组合策略可能会使胰腺癌对免疫疗法敏感。以 PARP 和 KRAS 抑制剂为代表的靶向疗法也在研究之中,这些疗法在改善无进展生存期和客观反应率方面显示出了优势。本综述讨论了当前的治疗模式,并重点介绍了胰腺癌的创新疗法。

The small inhibitor WM-1119 effectively targets KAT6A-rearranged AML, but not KMT2A-rearranged AML, despite shared KAT6 genetic dependency 小型抑制剂 WM-1119 可有效抑制 KAT6A 重组急性髓细胞性白血病,但不能抑制 KMT2A 重组急性髓细胞性白血病,尽管 KAT6 具有共同的遗传依赖性。

The epigenetic factors KAT6A (MOZ/MYST3) and KMT2A (MLL/MLL1) interact in normal hematopoiesis to regulate progenitors’ self-renewal. Both proteins are recurrently translocated in AML, leading to impairment of critical differentiation pathways in these malignant cells. We evaluated the potential of different KAT6A therapeutic targeting strategies to alter the growth of KAT6A and KMT2A rearranged AMLs. We investigated the action and potential mechanisms of the first-in-class KAT6A inhibitor, WM-1119 in KAT6A and KMT2A rearranged (KAT6Ar and KMT2Ar) AML using cellular (flow cytometry, colony assays, cell growth) and molecular (shRNA knock-down, CRISPR knock-out, bulk and single-cell RNA-seq, ChIP-seq) assays. We also used two novel genetic murine KAT6A models combined with the most common KMT2Ar AML, KMT2A::MLLT3 AML. In these murine models, the catalytic activity of KAT6A, or the whole protein, can be conditionally abrogated or deleted. These models allowed us to compare the effects of specific KAT6A KAT activity inhibition with the complete deletion of the whole protein. Finally, we also tested these therapeutic approaches on human AML cell lines and primary patient AMLs. We found that WM-1119 completely abrogated the proliferative and clonogenic potential of KAT6Ar cells in vitro. WM-1119 treatment was associated with a dramatic increase in myeloid differentiation program. The treatment also decreased stemness and leukemia pathways at the transcriptome level and led to loss of binding of the fusion protein at critical regulators of these pathways. In contrast, our pharmacologic and genetic results indicate that the catalytic activity of KAT6A plays a more limited role in KMT2Ar leukemogenicity, while targeting the whole KAT6A protein dramatically affects leukemic potential in murine KMT2A::MLLT3 AML. Our study indicates that inhibiting KAT6A KAT activity holds compelling promise for KAT6Ar AML patients. In contrast, targeted degradation of KAT6A, and not just its catalytic activity, may represent a more appropriate therapeutic approach for KMT2Ar AMLs.
表观遗传因子KAT6A(MOZ/MYST3)和KMT2A(MLL/MLL1)在正常造血过程中相互作用,调节祖细胞的自我更新。这两种蛋白在急性髓细胞性白血病中反复易位,导致这些恶性细胞的关键分化途径受损。我们评估了不同的 KAT6A 靶向治疗策略改变 KAT6A 和 KMT2A 重排急性髓细胞性白血病生长的潜力。我们采用细胞(流式细胞仪、集落测定、细胞生长)和分子(shRNA 敲除、CRISPR 敲除、大体和单细胞 RNA-seq、ChIP-seq)测定方法,研究了一流的 KAT6A 抑制剂 WM-1119 在 KAT6A 和 KMT2A 重排(KAT6Ar 和 KMT2Ar)AML 中的作用和潜在机制。我们还使用了两种新型遗传小鼠 KAT6A 模型与最常见的 KMT2Ar AML(KMT2A::MLLT3 AML)相结合。在这些小鼠模型中,KAT6A 或整个蛋白质的催化活性可被有条件地削弱或删除。通过这些模型,我们可以比较特异性 KAT6A KAT 活性抑制与完全删除整个蛋白的效果。最后,我们还在人类急性髓细胞白血病细胞系和原发性急性髓细胞白血病患者身上测试了这些治疗方法。我们发现,WM-1119 能完全抑制 KAT6Ar 细胞在体外的增殖和克隆生成潜能。WM-1119 治疗与骨髓分化程序的显著增加有关。治疗还在转录组水平上减少了干性和白血病通路,并导致融合蛋白与这些通路的关键调节因子失去结合。相比之下,我们的药理学和遗传学研究结果表明,KAT6A的催化活性在KMT2Ar致白血病中的作用较为有限,而靶向整个KAT6A蛋白则会显著影响小鼠KMT2A::MLLT3 AML的白血病潜能。我们的研究表明,抑制 KAT6A KAT 活性为 KAT6Ar AML 患者带来了令人信服的前景。相比之下,靶向降解 KAT6A(而不仅仅是其催化活性)可能是治疗 KMT2Ar AML 更为合适的方法。
