U2小核核糖核蛋白(snRNP)对pre-mRNA分支位点(BS)的选择对于剪接前体 (A complex)的组装至关重要。RNA解旋酶PRP5校对BS选择，但其潜在机制尚不清楚。2024年1月9日，西湖大学施一公及中国科学技术大学张晓峰共同通讯在Nature Structural & Molecular Biology 在线发表题为“Structural insights into branch site proofreading by human spliceosome”的研究论文，该研究报告了导致前质体组装的两个顺序复合物的原子结构:人类17S U2 snRNP和跨外显子pre-A复合物。PRP5主要通过酸性环占领SF3B1的RNA通路锚定在17S U2 snRNP上；PRP5的解旋酶结构域与U2 snRNA结合；U2 snRNA与BS相互作用的茎环(BSL)被TAT-SF1屏蔽，无法与BS接合。在pre-A配合物中，形成初始的U2-BS双相;PRP5的易位解旋酶结构域停留在U2 snRNA上，酸性环仍然占据RNA路径。pre-A构象被剪接因子SF1、DNAJC8和SF3A2特别稳定。癌症衍生的SF3B1突变破坏了其与PRP5的关联，损害了BS校对。总之，这些发现揭示了PRP5对剪接前体组装和BS选择或校对的关键见解。另外，2024年1月2日，上海科技大学刘如娟、西湖大学施一公及圣裘德儿童医院Xu Beisi等团队合作在Nucleic Acids Research 在线发表题为“THUMPD2 catalyzes the N2-methylation of U6 snRNA of the spliceosome catalytic center and regulates pre-mRNA splicing and retinal degeneration ”的研究论文，该研究发现一种RNA修饰-N2 -甲基鸟苷(m2G)沉积在U6 snRNA的G72上(剪接体的催化中心)，促进了人类细胞中有效的pre-mRNA剪接活性。这种修饰在脊椎动物中被证实是保守的。通过明确识别U6特异性序列和结构元件，THUMPD2被证明是负责U6 m2G72的甲基转移酶。敲除THUMPD2消除了U6 m2G72，破坏了pre-mRNA剪接活性，导致人类细胞中内源性pre-mRNA的数千个可选剪接事件发生变化。值得注意的是，异常剪接的pre-mRNA群体引发了无义介导的mRNA衰变途径。进一步表明，THUMPD2与年龄相关性黄斑变性和视网膜功能有关。因此，该研究证明了主要剪接体的RNA表观遗传修饰如何调节全局前mRNA剪接并影响生理和疾病。Pre-mRNA的剪接由剪接体执行，这是一种动态的超分子机器。剪接体通过识别内含子的保守元件:5 ' -剪接位点(5 'SS)、BS、聚嘧啶束(PPT)和3 ' -剪接位点(3 'SS)，组装在pre-mRNA上。首先，U1 snRNP、SF1、U2AF2和U2AF1分别识别5'SS、BS、PPT和3'SS，形成E complex。然后，U2 snRNP取代SF1，使U2 snRNA与BS之间形成双工，从而形成A complex。在高等真核生物中，大多数基因通过选择不同的剪接位点进行选择性剪接。因此，选择BS的A complex的形成是剪接调节的焦点。遗憾的是，人们对E-to-A转换背后的步骤知之甚少。RNA解旋酶PRP5(也称为DDX46)在A complex的组装过程中起关键作用。在人类17S U2 snRNP中，U2 snRNA无法与BS配对，因为U2 snRNA的相关序列形成双链BSL。ATP被PRP5水解导致BSL解绕，从而促进U2-BS双相的形成。在酵母中，Prp5可能校对U2-BS双工，因为Prp5突变允许使用隐性BS和3'SS。然而，PRP5调控剪接保真度的机制尚不清楚。17S人U2 snRNP和人pre-A剪接体的冷冻电镜结构（图源自Nature Structural & Molecular Biology ）大多数已知的癌症衍生的RNA剪接失调突变影响SF3B1的HEAT重复序列中的残基。这些突变大部分聚集在SF3B1的RNA通路上。Hsh155基因中的部分相应突变改变了Prp5相互作用和BS选择。尽管有这些诱人的线索，但这些癌症突变如何干扰正常剪接仍然是一个谜。该研究报道了人类17S U2 snRNP的高分辨率冷冻电镜(cryo-EM)结构和剪接抑制剂捕获的交叉外显子pre-A complex。结合结构导向的生化分析，该研究提出了一个校对BS选择和A complex组装的工作模型。总的来说，该研究为理解剪接体的早期组装过程以及分支位点的识别和选择机制提供了重要的结构信息，同时也为与癌症相关的SF3B1突变的致病机制提供了新的见解。参考文献：Zhang X, Zhan X, Bian T, Yang F, et al.

(NASDAQ: CRIS), a biotechnology company focused on the development of emavusertib, an orally available, small molecule IRAK4 inhibitor for the treatment of hematologic malignancies, today reported its business update and financial results for the quarter ended September 30, 2023. "Since the removal of the partial clinical hold, we have re-started patient enrollment in both the Phase 1/2 TakeAim Leukemia monotherapy and TakeAim Lymphoma combination studies and expect to initiate a triplet combination study in AML in the fourth quarter. We also expect to present updated data from the TakeAim Lymphoma combination study at ASH in December," said James Dentzer, President and CEO of Curis. Third Quarter 2023 and Recent Operational Highlights Emavusertib (IRAK4 Inhibitor) TakeAim Leukemia Curis is currently enrolling relapsed or refractory (R/R) AML/MDS patients with FLT3 or spliceosome mutation (U2AF1 or SF3B1) who have received < 3 prior lines of treatment. The Company expects additional data from this study in the first half of 2024. The Company expects to initiate a triplet combination study of emavusertib with azacitidine and venetoclax in the fourth quarter. This Phase 1 study is intended to evaluate emavusertib's safety, as well as its ability enhance the effectiveness of azacitidine and venetoclax. Initial data from this study is expected in the second half of 2024. TakeAim Lymphoma Curis is focusing its lymphoma clinical development efforts on Primary CNS lymphoma (PCNSL), a rare form of extranodal non-Hodgkin lymphoma for which there are limited treatment options. The Company is currently enrolling PCNSL patients in its TakeAim Lymphoma study in which patients are being treated with a combination of emavusertib and ibrutinib. The Company will present updated data from the study at the 65th ASH Annual Meeting December 9-12, 2023, which will include a PCNSL patient subset. Upcoming Milestones Curis expects updated clinical data from the TakeAim Lymphoma combination study with ibrutinib at the ASH Annual Meeting. The Company expects updated clinical data from the TakeAim Leukemia monotherapy study in the first half of 2024. The Company expects initial clinical data from the triplet combination study of emavusertib with azacitidine and venetoclax to treat AML patients in the second half of 2024. Corporate In July 2023, Curis completed a registered direct offering with net proceeds of approximately $13.8 million. On September 28, 2023, the Company effected a 1-for-20 reverse stock split of its common stock. Third Quarter 2023 Financial Results For the third quarter of 2023, Curis reported a net loss of $12.2 million or $2.13 per share on both a basic and diluted basis as compared to $13.3 million or $2.83 per share on both a basic and diluted basis, for the same period in 2022. Curis reported a net loss of $35.7 million or $6.96 per share on both a basic and diluted basis, for the nine months ended September 30, 2023 as compared to a net loss of $45.3 million or $9.82 per share on both a basic and diluted basis for the same period in 2022. Revenues for the third quarters of 2023 and 2022 were both $2.8 million. Revenues for both periods consist of royalty revenues from Genentech and Roche's sales of Erivedge®. Revenues for the nine months ended September 30, 2023 and 2022 were both $7.3 million. Research and development expenses were $10.4 million for the third quarter of 2023, as compared to $10.8 million for the same period in 2022. The decrease was primarily attributable to lower employee-related costs due to a reduction in headcount, partially offset by increased clinical costs. Research and development expenses were $29.5 million for the nine months ended September 30, 2023, as compared to $34.6 million for the same period in 2022. General and administrative expenses were $4.8 million for the third quarter of 2023, as compared to $4.6 million for the same period in 2022. The increase was primarily attributable to higher professional, legal, and consulting services costs. General and administrative expenses were $13.8 million for the nine months ended September 30, 2023, as compared to $15.3 million for the same period in 2022. Other income, net was $0.2 million for the third quarter of 2023, as compared to other expense, net of $0.7 million for the same period in 2022. Other income (expense), net primarily consisted of interest income partially offset by non-cash expense related to the sale of future royalties.

LEXINGTON, Mass., July 6, 2023 /PRNewswire/ -- Curis, Inc., (Nasdaq: CRIS), a biotechnology company focused on the development of emavusertib, an orally available small molecule triple target inhibitor (IRAK4, FLT3 and CLK) for the treatment of hematologic malignancies, today announced that the U.S. Food and Drug Administration (FDA) has removed the partial clinical hold on the TakeAim Leukemia Phase 1/2 study of emavusertib. Further, the recommended phase 2 dose (RP2D) for emavusertib as a monotherapy has been established at 300 mg BID in patients with Acute Myelogenous Leukemia (AML) or Myelodysplastic Syndromes (MDS). "We are pleased to announce that FDA has removed the partial clinical hold on the TakeAim Leukemia study and that we are proceeding with 300 mg BID as our RP2D. We are working with our clinical sites to enroll targeted patients with AML (patients with a FLT3 or spliceosome mutation who have received ≤ 2 prior lines of treatment). We also plan to initiate a front-line combination study of emavusertib with azacitidine and venetoclax. We believe emavusertib has the potential to be the cornerstone agent in the treatment of hematological malignancies." said James Dentzer, President and Chief Executive Officer of Curis. "In 2024, we expect to have updated data from the TakeAim Leukemia monotherapy study, clarification of a monotherapy registrational study design, and initial data from an azacitidine and venetoclax combination study." On April 4, 2022, the Company announced that the FDA placed a partial clinical hold on the TakeAim Leukemia study. On August 30, 2022, the Company announced that the FDA notified Curis that it may resume enrollment of additional patients in the monotherapy dose finding phase of the TakeAim Leukemia study, so that the Company could enroll at least nine additional patients at the 200 mg BID dose level. On July 6, 2023, the Company announced the FDA had removed the partial clinical hold on the TakeAim Leukemia study and that the RP2D has been established at 300 mg BID. In the TakeAim Leukemia study, as of the March 17, 2023 data cutoff for patients dosed prior to February 9, 2023, 84 patients received emavusertib monotherapy, ranging from doses of 200 mg to 500 mg BID. Significant blast count reductions have been observed across all patient groups, regardless of dose level, mutation status, or number of prior lines of treatment. Emerging from these data are two genetically-defined subpopulations of relapsed/refractory (R/R) patients who have demonstrated compelling responses in monotherapy: AML patients with FLT3 mutation and AML patients with spliceosome mutation (U2AF1 or SF3B1 mutation) who have received ≤ 2 prior lines of treatment. In these subpopulations of evaluable patients (patients whose disease has been determined to be evaluable for objective response with baseline and post-treatment marrow assessments) treated with 300 mg BID, 2 of 3 patients with a FLT3 mutation achieved a CR (Complete Response), and 2 of 3 patients with spliceosome mutation achieved a CR or CRh (Complete Response with Partial Hematologic Recovery). The duration of response for these patients ranged from 5.6 to 7.0 months. "A significant unmet need remains for patients with AML and MDS with the majority of front-line patients relapsing with currently available treatment options," said Dr. Reinhard von Roemeling, Senior Vice President of Clinical Development of Curis. "Emavusertib has the potential to be uniquely positioned as an addition to frontline therapy in combination with standard of care and also as a monotherapy in targeted R/R patient populations." About emavusertib (CA-4948) Emavusertib is a triple target inhibitor (IRAK4, FLT3 and CLK). IRAK4 plays an essential role in the toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) signaling pathways, which are frequently dysregulated in patients with cancer. TLRs and the IL-1R family signal through the adaptor protein MYD88, which results in the assembly and activation of IRAK4, initiating a signaling cascade that induces cytokine and survival factor expression mediated by the NF-κB protein complex. Preclinical studies targeting IRAK1/4 in combination with FLT3 have demonstrated the ability to overcome the adaptive resistance incurred when targeting FLT3 alone. Further, emavusertib has shown anti-tumor activity across a broad range of hematologic malignancies including monotherapy activity in patient-derived xenografts and synergy with both azacitidine and venetoclax.
