Pulmonary oncological pathologies are an important public health problem and the association with other pulmonary lesions may pose difficulties in diagnosis and staging or require different treatment options. To address this complexity, we conducted a retrospective observational study at the Marius Nasta Institute of Pneumophthisiology, Bucharest, Romania. Our study focused on patients admitted in 2019 with non-small-cell lung carcinoma and associated pulmonary lesions identified through surgical resection specimens. Among the 314 included patients, multiple pulmonary nodules were observed on macroscopic examination, with 12% (N = 37) exhibiting nonmalignant etiologies upon microscopic examination. These findings underscore the challenge of preoperative staging. Patients with coexisting nonmalignant lesions were similar in age, smoking habits, and professional or environmental exposure by comparison with those who presented only malignant lesions. The presentation of coexisting malignant and nonmalignant lesions may pose difficulties in diagnosing and staging pulmonary cancer.
肺部肿瘤病变是一个重要的公共卫生问题,与其他肺部病变的关联可能会给诊断和分期带来困难,或需要不同的治疗方案。为了解决这一复杂问题,我们在罗马尼亚布加勒斯特马里乌斯-纳斯塔肺病研究所开展了一项回顾性观察研究。我们的研究重点是 2019 年入院的非小细胞肺癌患者,以及通过手术切除标本确定的相关肺部病变。在纳入的 314 名患者中,经宏观检查可观察到多个肺结节,其中 12%(N = 37)经显微镜检查显示为非恶性病因。这些发现凸显了术前分期的挑战性。与仅出现恶性病变的患者相比,并存非恶性病变的患者在年龄、吸烟习惯、职业或环境接触方面都很相似。同时存在恶性和非恶性病变可能会给肺癌的诊断和分期带来困难。

Hyaluronic acid (HA) is a prominent component of the extracellular matrix, and its interactions with HA-interacting molecules (HAIMs) play a critical role in cancer development and disease progression. This review explores the multifaceted role of HAIMs in the context of cancer, focusing on their influence on disease progression by dissecting relevant cellular and molecular mechanisms in tumour cells and the tumour microenvironment. Cancer progression can be profoundly affected by the interactions between HA and HAIMs. They modulate critical processes such as cell adhesion, migration, invasion, and proliferation. The TME serves as a dynamic platform in which HAIMs contribute to the formation of a unique niche. The resulting changes in HA composition profoundly influence the biophysical properties of the TME. These modifications in the TME, in conjunction with HAIMs, impact angiogenesis, immune cell recruitment, and immune evasion. Therefore, understanding the intricate interplay between HAIMs and HA within the cancer context is essential for developing novel therapeutic strategies. Targeting these interactions offers promising avenues for cancer treatment, as they hold the potential to disrupt critical aspects of disease progression and the TME. Further research in this field is imperative for advancing our knowledge and the treatment of cancer.
透明质酸(HA)是细胞外基质的重要组成部分,它与HA相互作用分子(HAIMs)的相互作用在癌症的发生和发展中起着至关重要的作用。这篇综述探讨了 HAIMs 在癌症中的多方面作用,通过剖析肿瘤细胞和肿瘤微环境中的相关细胞和分子机制,重点关注 HAIMs 对疾病进展的影响。HA 和 HAIMs 之间的相互作用会对癌症的进展产生深远影响。它们会调节细胞粘附、迁移、侵袭和增殖等关键过程。TME是一个动态平台,其中的HAIMs有助于形成独特的龛位。由此产生的 HA 成分变化深刻影响着 TME 的生物物理特性。TME 中的这些变化与 HAIMs 一起影响血管生成、免疫细胞招募和免疫逃避。因此,了解癌症背景下 HAIMs 与 HA 之间错综复杂的相互作用对于开发新型治疗策略至关重要。以这些相互作用为靶点为癌症治疗提供了前景广阔的途径,因为它们有可能破坏疾病进展和TME的关键环节。为了增进我们对癌症的了解和治疗,必须在这一领域开展进一步的研究。

The vascular endothelial growth factors (VEGFs) and their receptors (VEGFRs) are key regulators of blood vessel formation, including in tumors, where their deregulated function can promote the production of aberrant, leaky blood vessels, supporting tumor development. Here we investigated the VEGFR1 ligand VEGF-B, which we demonstrate to be expressed in tumor cells and in tumor stroma and vasculature across a range of tumor types. We examined the anti-VEGF-B-specific monoclonal antibody 2H10 in preclinical xenograft models of breast and colorectal cancer, in comparison with the anti-VEGF-A antibody bevacizumab. Similar to bevacizumab, 2H10 therapy was associated with changes in tumor blood vessels and intra-tumoral diffusion consistent with normalization of the tumor vasculature. Accordingly, treatment resulted in partial inhibition of tumor growth, and significantly improved the response to chemotherapy. Our studies indicate the importance of VEGF-B in tumor growth, and the potential of specific anti-VEGF-B treatment to inhibit tumor development, alone or in combination with established chemotherapies.
血管内皮生长因子(VEGFs)及其受体(VEGFRs)是血管形成的关键调节因子,包括在肿瘤中,它们的功能失调可促进异常、渗漏血管的生成,从而支持肿瘤的发展。在这里,我们研究了 VEGFR1 配体 VEGF-B,结果表明它在多种肿瘤类型的肿瘤细胞、肿瘤基质和血管中都有表达。我们在乳腺癌和结直肠癌的临床前异种移植模型中研究了抗 VEGF-B 特异性单克隆抗体 2H10,并与抗 VEGF-A 抗体贝伐珠单抗进行了比较。与贝伐珠单抗类似,2H10疗法与肿瘤血管和瘤内扩散的变化有关,与肿瘤血管正常化一致。因此,治疗可部分抑制肿瘤生长,并显著改善对化疗的反应。我们的研究表明了VEGF-B在肿瘤生长中的重要性,以及特异性抗VEGF-B治疗单独或与现有化疗药物联合抑制肿瘤发生的潜力。

Background: Invasive lobular carcinoma (ILC), the most common special type of breast cancer (BC), has unique clinical behaviour and is different from invasive ductal carcinoma of no special type (IDC-NST). However, ILC further comprises a diverse group of tumours with distinct features. This study aims to examine the clinicopathological and prognostic features of different variants of ILC, with a particular focus on characterising aggressive subtypes. Methods: A large (n = 7140) well-characterised and histologically reviewed BC cohort with treatment and long-term follow-up data was investigated. The cohort was classified based on the WHO classification of tumours into main histological subtypes, including ILC and IDC-NST. ILCs were further classified into variants. Clinicopathological parameters and patient outcomes in terms of BC-specific survival (BCSS) and disease-free survival (DFS) were evaluated. Results: ILC constituted 11% of the cohort. The most common non-classic ILC variants were pleomorphic (pILC) and solid (sILC), constituting 19% of ILC. Compared to classic and related variants (alveolar, trabecular, papillary, and tubulolobular; cILC), pILC and sILC variants were associated with aggressive tumour characteristics. The histologic grade of ILC was an important prognostic variable. The survival patterns identified an aggressive ILC subtype encompassing pILC and high-grade sILC. These tumours, which comprised 14% of the cases, were associated with clinicopathological characteristics of poor prognosis and had high BC-specific death and recurrence rates compared not only to cILC (p < 0.001) but also to IDC-NST (p = 0.02) patients. Contrasting this, cILC patients had significantly longer BCSS and DFS than IDC-NST patients in the first 10 to 15 years of follow-up. Adjuvant chemotherapy did not improve the outcome of patients with aggressive ILC subtypes. Conclusions: pILC and high-grade sILC variants comprise an aggressive ILC subtype associated with poor prognostic characteristics and a poor response to chemotherapy. These results warrant confirmation in randomised clinical trials.
背景:浸润性小叶癌(ILC)是乳腺癌(BC)中最常见的特殊类型,具有独特的临床表现,不同于无特殊类型的浸润性导管癌(IDC-NST)。然而,ILC 还包括一组具有不同特征的肿瘤。本研究旨在探讨 ILC 不同变异的临床病理和预后特征,尤其关注侵袭性亚型的特征。研究方法研究人员调查了一个具有治疗和长期随访数据、特征明确、组织学回顾性良好的 BC 队列(n = 7140)。根据世界卫生组织(WHO)对肿瘤的分类,该队列被分为主要的组织学亚型,包括ILC和IDC-NST。ILC又分为变异型。评估了临床病理参数以及 BC 特异性生存率(BCSS)和无病生存率(DFS)方面的患者预后。结果显示ILC占队列的11%。最常见的非经典ILC变异是多形性(pILC)和实变性(sILC),占ILC的19%。与经典变体和相关变体(肺泡型、小梁型、乳头型和小管型;cILC)相比,pILC 和 sILC 变体具有侵袭性肿瘤特征。ILC的组织学分级是一个重要的预后变量。生存模式确定了一种侵袭性ILC亚型,包括pILC和高级别sILC。这些肿瘤占病例总数的14%,具有预后不良的临床病理特征,与cILC(p < 0.001)和IDC-NST(p = 0.02)患者相比,其BC特异性死亡率和复发率都很高。与此形成鲜明对比的是,在最初的10至15年随访中,cILC患者的BCSS和DFS明显长于IDC-NST患者。辅助化疗并不能改善侵袭性 ILC 亚型患者的预后。结论:pILC 和高级别 sILC 变体构成了侵袭性 ILC 亚型,其预后特征差,对化疗反应差。这些结果值得在随机临床试验中加以证实。

Sinonasal intestinal-type adenocarcinoma (ITAC) is a very rare, closely occupational-related tumor with strong histological similarities to colorectal cancer (CRC). In the latter, tumor budding (TB) is widely recognized as a negative prognostic parameter. The aim of this study was to evaluate the prognostic role of TB in ITAC and to correlate it with other established or emerging biomarkers of the disease, such as p53 and deficient DNA mismatch repair (MMR) system status/microsatellite instability (MSI). We retrospectively analyzed 32 consecutive specimens of patients with ITAC diagnosis treated in two institutions in Northern Italy. We reviewed surgical specimens for TB evaluation (low-intermediate/high); p53 expression and MMR proteins were evaluated via immunohistochemistry. Results were retrospectively stratified using clinical data and patients’ outcomes. According to bud counts, patients were stratified into two groups: intermediate/high budding (>4 TB) and low budding (≤4 TB). Patients with high TB (>4) have an increased risk of recurrence and death compared to those with low TB, with a median survival of 13 and 54 months, respectively. On multivariate analysis, considering TB, therapy, and stage as covariates, TB emerged as an independent prognostic factor net of the stage of disease or type of therapy received. No impact of p53 status as a biomarker of prognosis was observed and no alterations regarding MMR proteins were identified. The results of the present work provide further significant evidence on the prognostic role of TB in ITAC and underline the need for larger multicenter studies to implement the use of TB in clinical practice.
鼻窦肠型腺癌(ITAC)是一种非常罕见的、与职业密切相关的肿瘤,在组织学上与结直肠癌(CRC)非常相似。在后者中,肿瘤萌芽(TB)被广泛认为是一个负面的预后参数。本研究旨在评估 TB 在 ITAC 中的预后作用,并将其与该疾病的其他已确定或新出现的生物标志物(如 p53 和 DNA 错配修复(MMR)系统缺陷状态/微卫星不稳定性(MSI))相关联。我们回顾性分析了意大利北部两家医疗机构治疗的 32 例 ITAC 诊断患者的连续标本。我们对手术标本进行了肺结核评估(低-中-高);通过免疫组化对 p53 表达和 MMR 蛋白进行了评估。我们利用临床数据和患者的预后对结果进行了回顾性分层。根据萌芽计数,患者被分为两组:中/高萌芽(>4 TB)和低萌芽(≤4 TB)。与低芽数患者相比,高芽数(>4)患者的复发和死亡风险更高,中位生存期分别为 13 个月和 54 个月。在多变量分析中,将结核病、治疗和分期作为协变量考虑,结核病成为一个独立的预后因素,不受疾病分期或接受的治疗类型的影响。作为预后生物标志物的 p53 状态没有影响,也没有发现 MMR 蛋白发生改变。本研究的结果为肺结核在 ITAC 中的预后作用提供了进一步的重要证据,并强调了在临床实践中使用肺结核进行更大规模的多中心研究的必要性。

Background. Langerhans cells (LCs) are professional Dendritic Cells (DCs) involved in immunoregulatory functions. At the skin level, LCs are immature. In response to tissue injuries, they migrate to regional Lymph Nodes (LNs), reaching a full maturation state. Then, they become effective antigen-presenting cells (APCs) that induce anti-cancer responses. Notably, melanoma patients present several DC alterations in the Sentinel Lymph Node (SLN), where primary antitumoral immunity is generated. LCs are the most represented DCs subset in melanoma SLNs and are expected to play a key role in the anti-melanoma response. With this paper, we aim to review the current knowledge and future perspectives regarding LCs and melanoma. Methods. A systematic review was carried out according to the PRISMA statement using the PubMed (MEDLINE) library from January 2004 to January 2024, searching for original studies discussing LC in melanoma. Results. The final synthesis included 15 articles. Several papers revealed significant LCs–melanoma interactions. Conclusions. Melanoma immune escape mechanisms include SLN LC alterations, favoring LN metastasis arrival/homing and melanoma proliferation. The SLN LCs of melanoma patients are defective but not irreversibly, and their function may be restored by appropriate stimuli. Thus, LCs represent a promising target for future immunotherapeutic strategies and cancer vaccines.
背景。朗格汉斯细胞(LCs)是参与免疫调节功能的专业树突状细胞(DCs)。在皮肤层面,朗格汉斯细胞尚未成熟。当组织受伤时,它们会迁移到区域淋巴结(LN),达到完全成熟状态。然后,它们成为有效的抗原递呈细胞(APC),诱导抗癌反应。值得注意的是,黑色素瘤患者的前哨淋巴结(SLN)中存在多种直流电改变,而主要的抗肿瘤免疫力就产生于前哨淋巴结。LCs 是黑色素瘤 SLN 中最具代表性的 DCs 亚群,预计将在抗黑色素瘤反应中发挥关键作用。本文旨在回顾有关 LCs 与黑色素瘤的现有知识和未来展望。方法。根据 PRISMA 声明,利用 PubMed (MEDLINE) 文库对 2004 年 1 月至 2024 年 1 月期间讨论黑色素瘤 LC 的原始研究进行了系统综述。结果。最终的综述包括 15 篇文章。多篇论文揭示了 LCs 与黑色素瘤之间的重要相互作用。结论。黑色素瘤免疫逃逸机制包括SLN LC改变,有利于LN转移到达/归巢和黑色素瘤增殖。黑色素瘤患者的SLN LCs存在缺陷,但并非不可逆转,适当的刺激可恢复其功能。因此,LCs 是未来免疫治疗策略和癌症疫苗的一个有希望的靶点。

Thus, LCs represent a promising target for future immunotherapeutic strategies and cancer vaccines.","PeriodicalId":504676,"journal":{"name":"Cancers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140970144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: The effects of steroid-sparing immunosuppressive agents (SSIAs), used for the treatment of immune-related adverse events (irAEs), on immune checkpoint inhibitor (ICI) antitumor activity is not well known. We compared tumor outcomes of patients who received corticosteroid monotherapy (CS) versus a corticosteroid plus SSIA (CS-SSIA) for irAE treatment, using statistical methods to address immortal time bias. Methods: We conducted a retrospective case-control study on patients ≥ 18 years with melanoma or non-small-cell lung cancer (NSCLC) treated with ≥1 ICI at a quaternary care center between 1 January 2016 and 11 January 2021. Patients were divided into two cohorts: CS or CS-SSIA. We used propensity score nearest-neighbor matching to match on tumor type, stage, and prior lines of therapy. Primary outcomes were progression-free survival (PFS) and overall survival (OS). Secondary outcomes included the time from the start of the irAE treatment to the irAE resolution. Hazard ratios (HRs) for PFS and OS were calculated using the Cox proportional hazard regression method with both (1) the time to the steroid and SSIA as time-varying covariates and (2) a binary exposure classification not accounting for the time to the treatment. Results: A total of 167 patients were included after matching (132 in the CS cohort and 35 in the CS-SSIA cohort). Sixty-six percent of all the patients had melanoma. The most common irAEs requiring treatment were gastroenterocolitis and hepatitis. In an adjusted analysis not accounting for immortal time bias, there were no significant differences in PFS (HR 0.75, 95% CI [0.46–1.23]) or OS (HR 0.82, 95% CI [0.46–1.47]). In analyses using a time-varying treatment indicator, there was a trend toward improved PFS in patients treated with SSIAs (HR 0.54, CI 0.26–1.10). There was no difference in OS (HR 1.11, CI 0.55–2.23). Patients with melanoma who specifically received infliximab had improved PFS compared to patients with CS only, after adjusting for immortal time bias (HR 0.32, CI 0.24–0.43). Conclusions: The use of SSIAs with CS did not have worse outcomes than CS monotherapy. In melanoma, our findings showed improved PFS for the use of infliximab versus steroid monotherapy for irAEs. Large, prospective, randomized controlled trials are needed to confirm these findings and guide the optimal treatment of irAEs.
背景:用于治疗免疫相关不良事件(irAEs)的类固醇疏松免疫抑制剂(SSIAs)对免疫检查点抑制剂(ICI)抗肿瘤活性的影响尚不十分清楚。我们比较了接受皮质类固醇单药治疗(CS)和皮质类固醇加SSIA(CS-SSIA)治疗irAE的患者的肿瘤预后,并使用统计方法解决了不朽时间偏倚问题。研究方法我们对2016年1月1日至2021年1月11日期间在一家四级医疗中心接受≥1种ICI治疗的≥18岁黑色素瘤或非小细胞肺癌(NSCLC)患者进行了一项回顾性病例对照研究。患者分为两组:CS 或 CS-SSIA。我们使用倾向得分近邻匹配法来匹配肿瘤类型、分期和先前的治疗方案。主要结果为无进展生存期(PFS)和总生存期(OS)。次要结果包括从开始接受irAE治疗到irAE缓解的时间。PFS和OS的危险比(HRs)采用Cox比例危险回归法进行计算,并将(1)接受类固醇和SSIA治疗的时间作为随时间变化的协变量;(2)二元暴露分类不考虑治疗时间。结果经过匹配后,共纳入了 167 名患者(132 人纳入 CS 队列,35 人纳入 CS-SSIA 队列)。66%的患者患有黑色素瘤。需要治疗的最常见irAE为胃肠结肠炎和肝炎。在不考虑不死时间偏差的调整分析中,PFS(HR 0.75,95% CI [0.46-1.23])和OS(HR 0.82,95% CI [0.46-1.47])没有显著差异。在使用时变治疗指标进行的分析中,接受 SSIAs 治疗的患者的 PFS 有改善趋势(HR 0.54,CI 0.26-1.10)。OS 方面没有差异(HR 1.11,CI 0.55-2.23)。与仅接受CS治疗的黑色素瘤患者相比,特别接受英夫利西单抗治疗的黑色素瘤患者的PFS有所改善,调整不死时间偏差后(HR为0.32,CI为0.24-0.43)。结论在使用 CS 的同时使用 SSIAs 的疗效并不比单用 CS 差。在黑色素瘤中,我们的研究结果表明,使用英夫利西单抗治疗irAEs比单用类固醇治疗的PFS有所改善。需要进行大型、前瞻性、随机对照试验来证实这些发现,并指导irAEs的最佳治疗方法。

Information on the financial toxicity experienced by Japanese patients with metastatic renal cell carcinoma (mRCC) is lacking, even though Japan has its own unique public health insurance system. Thus, a web-based survey was conducted to evaluate the financial toxicity experienced by Japanese mRCC patients using the COmprehensive Score for financial Toxicity (COST) tool. This study enrolled Japanese patients who underwent, or were undergoing, systemic therapy for mRCC. The outcomes evaluated were the distribution of COST scores, the correlation between COST and quality of life (QOL) assessed by the Functional Assessment of Cancer Therapy-General (FACT-G) scale, and demographic factors associated with financial toxicity. The median (range) COST score was 19.0 (3.0–36.0). The Pearson correlation coefficient for COST and FACT-G total scores was 0.40. Univariate analysis revealed that not having private health insurance and lower household income per year were significantly associated with lower COST scores. Multivariate analyses showed that age < 65 years and not having private health insurance were significantly associated with lower COST scores. This study revealed that Japanese mRCC patients experience adverse financial impacts even under the universal health insurance coverage system available in Japan, and financial toxicity negatively affects their QOL.
尽管日本拥有自己独特的公共医疗保险体系,但有关日本转移性肾细胞癌(mRCC)患者所经历的经济毒性的信息却十分匮乏。因此,我们使用经济毒性综合评分(COST)工具开展了一项网络调查,以评估日本 mRCC 患者所经历的经济毒性。这项研究招募了接受或正在接受系统治疗的日本 mRCC 患者。评估的结果包括 COST 分数的分布、COST 与癌症治疗功能评估(FACT-G)量表评估的生活质量(QOL)之间的相关性,以及与经济毒性相关的人口学因素。COST 评分的中位数(范围)为 19.0(3.0-36.0)。COST 和 FACT-G 总分的皮尔逊相关系数为 0.40。单变量分析表明,没有私人医疗保险和家庭年收入较低与较低的 COST 分数显著相关。多变量分析表明,年龄小于 65 岁和没有私人医疗保险与较低的 COST 分数明显相关。这项研究表明,即使在日本现有的全民医疗保险制度下,日本的 mRCC 患者也会受到不利的经济影响,而且经济压力会对他们的 QOL 产生负面影响。

This retrospective multicenter study examines therapy-induced orbital and ocular MRI findings in retinoblastoma patients following selective intra-arterial chemotherapy (SIAC) and quantifies the impact of SIAC on ocular and optic nerve growth. Patients were selected based on medical chart review, with inclusion criteria requiring the availability of posttreatment MR imaging encompassing T2-weighted and T1-weighted images (pre- and post-intravenous gadolinium administration). Qualitative features and quantitative measurements were independently scored by experienced radiologists, with deep learning segmentation aiding total eye volume assessment. Eyes were categorized into three groups: eyes receiving SIAC (Rb-SIAC), eyes treated with other eye-saving methods (Rb-control), and healthy eyes. The most prevalent adverse effects post-SIAC were inflammatory and vascular features, with therapy-induced contrast enhancement observed in the intraorbital optic nerve segment in 6% of patients. Quantitative analysis revealed significant growth arrest in Rb-SIAC eyes, particularly when treatment commenced ≤ 12 months of age. Optic nerve atrophy was a significant complication in Rb-SIAC eyes. In conclusion, this study highlights the vascular and inflammatory adverse effects observed post-SIAC in retinoblastoma patients and demonstrates a negative impact on eye and optic nerve growth, particularly in children treated ≤ 12 months of age, providing crucial insights for clinical management and future research.
这项回顾性多中心研究探讨了视网膜母细胞瘤患者在接受选择性动脉内化疗(SIAC)后由治疗引起的眼眶和眼部 MRI 结果,并量化了 SIAC 对眼部和视神经生长的影响。根据病历审查筛选出患者,纳入标准要求提供治疗后的磁共振成像,包括T2加权和T1加权图像(静脉注射钆前后)。定性特征和定量测量结果由经验丰富的放射科医生独立评分,并通过深度学习分割辅助评估眼球总体积。眼球被分为三组:接受 SIAC(Rb-SIAC)治疗的眼球、接受其他护眼方法治疗的眼球(Rb-对照组)和健康眼球。SIAC治疗后最常见的不良反应是炎症和血管特征,6%的患者在眶内视神经段观察到治疗引起的对比度增强。定量分析显示,Rb-SIAC 患眼的生长明显停滞,尤其是在治疗开始时间小于 12 个月时。视神经萎缩是 Rb-SIAC 眼睛的一个重要并发症。总之,本研究强调了在视网膜母细胞瘤患者中观察到的SIAC术后血管和炎症不良反应,并显示了对眼睛和视神经生长的负面影响,尤其是在接受治疗的年龄小于12个月的儿童中,这为临床管理和未来研究提供了重要启示。

Pseudokinases are catalytically inactive proteins in the human genome that lack the ability to transfer phosphate from ATP to their substrates. The Tribbles family of pseudokinases contains three members: Tribbles 1, 2, and 3. Tribbles 1 has recently gained importance because of its involvement in various diseases, including cancer. It acts as a scaffolding protein that brings about the degradation of its substrate proteins, such as C/EBPα/β, MLXIPL, and RAR/RXRα, among others, via the ubiquitin proteasome system. It also serves as an adapter protein, which sequesters different protein molecules and activates their downstream signaling, leading to processes, such as cell survival, cell proliferation, and lipid metabolism. It has been implicated in cancers such as AML, prostate cancer, breast cancer, CRC, HCC, and glioma, where it activates oncogenic signaling pathways such as PI3K-AKT and MAPK and inhibits the anti-tumor function of p53. TRIB1 also causes treatment resistance in cancers such as NSCLC, breast cancer, glioma, and promyelocytic leukemia. All these effects make TRIB1 a potential drug target. However, the lack of a catalytic domain renders TRIB1 “undruggable”, but knowledge about its structure, conformational changes during substrate binding, and substrate binding sites provides an opportunity to design small-molecule inhibitors against specific TRIB1 interactions.
假激酶是人类基因组中催化不活跃的蛋白质,它们缺乏将磷酸从 ATP 转移到底物的能力。假激酶 Tribbles 家族包含三个成员:Tribbles 1、2 和 3。Tribbles 1 最近因与包括癌症在内的多种疾病有关而变得越来越重要。它是一种支架蛋白,可通过泛素蛋白酶体系统降解其底物蛋白,如 C/EBPα/β、MLXIPL 和 RAR/RXRα 等。它还是一种适配器蛋白,可固定不同的蛋白质分子,并激活其下游信号转导,导致细胞存活、细胞增殖和脂质代谢等过程。它与 AML、前列腺癌、乳腺癌、CRC、HCC 和胶质瘤等癌症有关,在这些癌症中,它激活了 PI3K-AKT 和 MAPK 等致癌信号通路,并抑制了 p53 的抗肿瘤功能。TRIB1 还会导致 NSCLC、乳腺癌、胶质瘤和早幼粒细胞白血病等癌症产生耐药性。所有这些作用使 TRIB1 成为潜在的药物靶点。然而,由于缺乏催化结构域,TRIB1 "不可药用",但对其结构、底物结合过程中的构象变化以及底物结合位点的了解,为设计针对特定 TRIB1 相互作用的小分子抑制剂提供了机会。
