简介

Serine/threonine-protein kinase component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. Also plays a role in meiosis and more particularly in spermatogenesis. Has redundant cellular functions with AURKB and can rescue an AURKB knockdown. Like AURKB, AURKC phosphorylates histone H3 at 'Ser-10' and 'Ser-28'. AURKC phosphorylates the CPC complex subunits BIRC5/survivin and INCENP leading to increased AURKC activity. Phosphorylates TACC1, another protein involved in cell division, at 'Ser-228'.

Comprehensive analysis of chromosomal breakpoints and candidate genes associated with male infertility: insights from cytogenetic studies and expression analyses

Article

作者: Kakavand, Kianoush ; Sabbaghian, Marjan ; Hassanzadeh, Vahideh ; Masoudi, Najmeh Sadat ; Meybodi, Anahita Mohseni ; Moradi, Shabnam Zarei ; Shahhoseini, Maryam ; Zamanian, Mohammadreza ; Hossein Garakani, Melika ; Ghaheri, Azadeh

The study aimed to investigate prevalent chromosomal breakpoints identified in balanced structural chromosomal anomalies and to pinpoint potential candidate genes linked with male infertility. This was acchieved through a comprehensive approach combining RNA-seq and microarray data analysis, enabling precise identification of candidate genes. The Cytogenetics data from 2,500 infertile males referred to Royan Research Institute between 2009 and 2022 were analyzed, with 391 cases meeting the inclusion criteria of balanced chromosomal rearrangement. Of these, 193 cases exhibited normal variations and were excluded from the analysis. By examining the breakpoints, potential candidate genes were suggested. Among the remaining 198 cases, reciprocal translocations were the most frequent anomaly (129 cases), followed by Robertsonian translocations (43 cases), inversions (34 cases), and insertions (3 cases).Some patients had more than one chromosomal abnormality. Chromosomal anomalies were most frequently observed in chromosomes 13 (21.1%), 14 (20.1%), and 1 (16.3%) with 13q12, 14q12, and 1p36.3 being the most prevalent breakpoints, respectively. Chromosome 1 contributed the most to reciprocal translocations (20.2%) and inversions (17.6%), while chromosome 14 was the most involved in the Robertsonian translocations (82.2%). The findings suggested that breakpoints at 1p36.3 and 14q12 might be associated with pregestational infertility, whereas breakpoints at 13q12 could be linked to both gestational and pregestational infertility. Several candidate genes located on common breakpoints were proposed as potentially involved in male infertility. Bioinformatics analyses utilizing three databases were conducted to examine the expression patterns of 78 candidate genes implicated in various causes of infertility.‏ In azoospermic individuals, significant differential expression was observed in 19 genes: 15 were downregulated (TSSK2, SPINK2, TSSK4, CDY1, CFAP70, BPY2, BTG4, FKBP6, PPP2R1B, SPECC1L, CENPJ, ‏SKA3, FGF9, NODAL, CLOCK), while four genes were upregulated ‏(‏HSPB1, MIF, PRF1, ENTPD6). In the case of Asthenozoospermia, seven genes showed significant upregulation (PRF1, DDX21, KIT, SRD5A3, MTCH1, DDX50, NODAL). Though RNA-seq data for Teratozoospermia were unavailable, microarray data revealed differential expression insix genes: three downregulated (BUB1, KLK4, PIWIL2) and three upregulated (AURKC, NPM2, RANBP2). These findings enhance our understanding of the molecular basis of male infertility and could provide valuable insights for future diagnostic and therapeutic strategies.

Surface-mutagenesis strategies to enable structural biology crystallization platforms

Article

作者: Hilpmann, André ; Egner, Ursula ; Hillig, Roman Christian ; Pütter, Vera ; Holton, Simon James ; Schaefer, Martina

A key prerequisite for the successful application of protein crystallography in drug discovery is to establish a robust crystallization system for a new drug-target protein fast enough to deliver crystal structures when the first inhibitors have been identified in the hit-finding campaign or, at the latest, in the subsequent hit-to-lead process. The first crucial step towards generating well folded proteins with a high likelihood of crystallizing is the identification of suitable truncation variants of the target protein. In some cases an optimal length variant alone is not sufficient to support crystallization and additional surface mutations need to be introduced to obtain suitable crystals. In this contribution, four case studies are presented in which rationally designed surface modifications were key to establishing crystallization conditions for the target proteins (the protein kinases Aurora-C, IRAK4 and BUB1, and the KRAS–SOS1 complex). The design process which led to well diffracting crystals is described and the crystal packing is analysed to understand retrospectively how the specific surface mutations promoted successful crystallization. The presented design approaches are routinely used in our team to support the establishment of robust crystallization systems which enable structure-guided inhibitor optimization for hit-to-lead and lead-optimization projects in pharmaceutical research.

Spatio-temporal requirements of Aurora kinase A in mouse oocyte meiotic spindle building

Article

作者: Drutovic, David ; Blengini, Cecilia S ; Schindler, Karen ; Schier, Jan ; Vaskovicova, Michaela

Meiotic spindles are critical to ensure chromosome segregation during gamete formation. Oocytes lack centrosomes and use alternative microtubule-nucleation mechanisms for spindle building. How these mechanisms are regulated is still unknown. Aurora kinase A (AURKA) is essential for mouse oocyte meiosis because in pro-metaphase I it triggers microtubule organizing-center fragmentation and its expression compensates for the loss of the two other Aurora kinases (AURKB/AURKC). Although knockout mouse models were useful for foundational studies, AURK spatial and temporal functions are not yet resolved. We provide high-resolution analyses of AURKA/AURKC requirements during meiotic spindle-building and identify the subcellular populations that carry out these functions: 1) AURKA is required in early spindle assembly and later for spindle stability, whereas 2) AURKC is required in late pro-metaphase, and 3) Targeted AURKA constructs expressed in triple AURK knockout oocytes reveal that spindle pole-localized AURKA is the most important population controlling spindle building and stability mechanisms.

新药 | 加科思宣布完成首例患者给药，Aurora A抑制剂迎资本热捧

关注并星标CPHI制药在线加科思药业于近日宣布，其自主研发的全球首创新药Aurora A（极光激酶A）抑制剂JAB-2485的I期临床研究在美国完成晚期实体瘤患者首例给药。临床前数据表明，JAB-2485在生化和细胞水平上具有高选择性，JAB-2485对Aurora A的抑制活性比对Aurora B的抑制活性高一千多倍，有潜力使小细胞肺癌、三阴乳腺癌等肿瘤患者受益。作为一种高选择性小分子Aurora A抑制剂，JAB-2485在细胞水平可以抑制Aurora A活性，诱导细胞凋亡，抑制肿瘤生长。 Aurora A也叫做极光激酶A，同时作用于MYC和Rb两条信号通路，适用于治疗Rb1基因缺失的肿瘤患者。Rb是一种抑癌基因，相当于细胞增殖过程中的“刹车”，当“刹车”发生突变后会失灵，造成细胞持续分裂，这就是癌症的成因。当前，Aurora A研发进展到哪一步了？Aurora激酶有什么功能？细胞周期调控因子Aurora Aurora激酶家族主要参与细胞有丝分裂的调控，其功能的丧失会影响细胞正常分裂，如影响胚胎发育的过程等。而如果这类激酶表达过于活跃，则会引起细胞分裂失控，导致癌症的发生。 Aurora激酶家族成员包括Aurora A、Aurora B和Aurora C，其中Aurora A/B在人体中广泛表达，而Aurora C主要在睾丸组织中表达。Aurora-A和Aurora-B虽然在序列水平上有一定的相似性，但它们的定位和功能在很大程度上是不重叠的。 Aurora A是Aurora激酶家族的重要成员。它在有丝分裂的G2/M期发挥重要作用，主要影响中心粒成熟、纺锤体形成等过程。Aurora A从细胞分裂的S期开始定位于复制的中心粒，随后被上游信号激活，启动细胞进入有丝分裂，并在G2/M转换阶段达到表达量和活性最高。同时在有丝分裂末期，Aurora A会被降解，直至新一轮细胞分裂启动。而在癌细胞中，Aurora A发生过表达或突变现象，而且Aurora A可以通过磷酸化调控多种起到抑癌作用的蛋白，包括P53和BRAC2等关键角色。Aurora A通过磷酸化Ser215和Ser315位点，抑制P53转录活性并增加降解，并且在乳腺癌、卵巢癌等癌种中被发现抑制BRAC2表达。虽然Aurora A在肿瘤的发生发展过程中意义重大，但其抑制剂的研发并非一帆风顺。 Aurora A抑制剂，进展并不顺利多项研究已证明Aurora A的过度表达与多种癌症的发生相关。而Aurora A抑制剂能够抑制肿瘤细胞的增殖、转移等，已成为细胞周期领域抗肿瘤靶向药物的研究热点。但是Aurora A抑制剂的研发并不顺利，在过去十年，先后有20余个Aurora A激酶抑制剂由于QT间期延长、骨髓抑制、嗜睡等毒副作用、患者受益有限等原因以临床失败而告终。目前全球尚无Aurora A激酶抑制剂获批上市。 2008年，武田斥资88亿美元，以53%的溢价将美国Millennium Pharmaceuticals公司收购，获得其Aurora A抑制剂候选药物——Alisertib。但是截至目前，武田研发管线中已不再更新这一项目信息。后来研究者发现，在第一代Aurora A抑制剂研发中，研究者把目光聚焦在泛抑制剂领域，它们对Aurora A和B都有抑制作用，结果由于选择性不高，副作用严重，往往伴随着严重的骨髓抑制毒性。于是，研究者们开始转向高选择性Aurora A抑制剂的研发。这类高选择性Aurora A抑制剂骨髓毒性降低，选择性较强。随着高选择性Aurora A抑制剂的出现，这一赛道重新获得资本热捧。全球在研Aurora A抑制剂 2018年，礼来以1.1亿美元首付款和4.65亿美元监管销售里程金的方式收购AurKa Pharma公司，获得其高选择性Aurora A抑制剂AK01，这款药物当时处于I期临床阶段，正在开展与奥希替尼联用治疗EGFR突变晚期转移性非鳞NSCLC的研究。目前，AK01正在开展针对Rb缺失广泛期小细胞肺癌、接受CDK4/6抑制剂联合内分泌疗法治疗后的转移性乳腺癌、复发难治成神经细胞瘤和其他实体瘤的临床I期研究。除礼来外，国内外一众药企也都投入到高选择性Aurora A抑制剂的研发中。目前全球在研Aurora A抑制剂（根据公开资料整理） ENMD-2076由Miikana Therapeutics研发，其作用机理为通过靶向Aurora A并抑制其活性，导致STAT3磷酸化水平下降，进而促进肿瘤细胞内趋化因子基因CXCL10和CXCL11的高表达。通过体外和小鼠模型实验发现，ENMD-2076通过激活肿瘤细胞趋化因子CXCL10和CXCL11的基因表达和分泌，来吸引更多的、对肿瘤具有杀伤作用的CD8+?T细胞进入肿瘤微环境，改变肿瘤微环境的免疫状态。另外，ENMD-2076与PD-1抗体联用，更有效抑制了三阴性乳腺癌在动物模型中的生长，提高了肿瘤免疫治疗的响应率。 TT-00420是药捷安康（南京）科技股份有限公司的核心产品，其通过抑制Aurora A和Aurora B以及参与血管生成的受体酪氨酸激酶表现出双重机制抑制肿瘤的增殖。 TT-00420在I期临床研究中展现了良好的安全性，目前已经在全球开展了多项肿瘤临床试验，试验中心包括MD Anderson Cancer Center、中国医学科学院肿瘤医院等。2019年，TT-00420获得了FDA授予的治疗胆管癌的孤儿药认证。 TAS119是由日本Taiho Pharmaceutical研发的一款高选择性Aurora A抑制剂。2020年6月，国内公司捷思英达宣布从Taiho引进TAS-119在肿瘤领域的全球独家开发和商业化权利。目前，TAS-119已在美国和欧洲完成了两项I期临床研究。 WJ05129是由微境生物研发的一种Aurora A抑制剂。它与RB1基因缺失或失活具有合成致死的效果，可以用于治疗小细胞肺癌和三阴乳腺癌等RB1 缺失或失活的恶性肿瘤。2020年，微境生物与君实生物签订了一份技术转让及合作协议，将包括WJ05129在内的4个药物项目50%的权益转让给了君实生物。作为新兴的抗癌靶标，Aurora激酶引起了不少研究机构和企业的兴趣。初代Aurora抑制剂大多是泛抑制剂，在疗效和安全性上存在欠缺。如今开发高选择性的Aurora A抑制剂成为了Aurora激酶靶向药物的研发趋势。目前这一赛道尚无药物获批上市，布局企业不多。对于国内药企来说，或许这是一种差异化的临床开发策略。参考来源： 1.Katsha, A., Belkhiri, A., Goff, L. et al.
