Tumor cells regulate their progression not only by the factors within their cell bodies but also by the secretome they produce and secrete. While their secretome significantly alters the fate of tumor cells themselves, they also regulate the growth of surrounding cells including both companion cancer and non-cancer cells. Tumor cell secretome consists of varying molecules that have been reported mostly tumor-promotive. Furthermore, their pro-tumor capability is enhanced by the application of chemotherapeutic agents. However, multiple lines of emerging evidence suggest that the tumor cell secretome can be tumor-suppressive in response to paracrine and endocrine signaling. This review introduces both tumor-promotive and tumor-suppressive secretomes, focusing on multi-tasking proteins in the intracellular and extracellular domains. We describe tumorigenic signaling that governs the nature of the tumor cell secretome and discuss the possibility of inducing tumor-suppressive proteomes as a novel option for cancer treatment. We evaluated the counterintuitive procedure to generate tumor-suppressive proteomes from a unique type of tumor-modifying cells, which are named “induced tumor-suppressing cells” (iTSCs).
肿瘤细胞不仅通过其细胞体内的因子,而且通过其产生和分泌的分泌组来调节其进程。虽然它们的分泌组显著改变肿瘤细胞本身的命运,但它们也调节周围细胞的生长,包括伴癌细胞和非癌细胞。肿瘤细胞分泌组由不同的分子组成,这些分子大多被报道为肿瘤促进分子。此外,它们的促肿瘤能力通过化疗药物的应用而增强。然而,多种新出现的证据表明,肿瘤细胞分泌组在响应旁分泌和内分泌信号时可能具有肿瘤抑制作用。本文综述了肿瘤促进和肿瘤抑制分泌组,重点介绍了细胞内和细胞外区域的多任务蛋白。我们描述了控制肿瘤细胞分泌组性质的致瘤性信号,并讨论了诱导肿瘤抑制蛋白质组作为癌症治疗的新选择的可能性。我们评估了从一种独特类型的肿瘤修饰细胞(称为“诱导肿瘤抑制细胞”(iTSCs))中产生肿瘤抑制蛋白质组的反直觉程序。

Tumor-Agnostic Biomarkers: Heed Caution, and Why Cell of Origin Still Matters 肿瘤不可知论的生物标志物:要小心,为什么细胞起源仍然很重要

Since the very beginnings of cancer therapy with chemotherapy, tumors have been treated according to the organ or tissue of origin. The advent of precision medicine however, has recently led to growing promise for tumor-agnostic biomarkers for targeted therapies and immunotherapies, such as NTRK fusions. Despite this, prominent examples such as BRAF V600E mutations in melanoma compared to colorectal cancer, in which the site of tumor origin dramatically influences the efficacy of targeted therapies, heeds caution against disregarding the importance of cell of origin. Indeed, another illustrative example, is the almost complete absence outside of cancers originating from the lung of the classical activating EGFR mutations—exon 19 deletions and exon 21 L858R mutations. Consequently, an understanding of lineage dependency and lineage-survival oncogenes may still offer significant mechanistic insights into the malignant transformation of tumors to ultimately identify further therapeutic vulnerabilities.
自从癌症化疗开始以来,肿瘤一直是根据起源的器官或组织来治疗的。然而,精准医学的出现最近带来了肿瘤不可知生物标志物用于靶向治疗和免疫治疗的希望,如NTRK融合。尽管如此,与结直肠癌相比,黑色素瘤中的BRAF V600E突变等突出例子表明,肿瘤起源部位显著影响靶向治疗的疗效,这需要谨慎对待,不要忽视起源细胞的重要性。事实上,另一个说明性的例子是,除了肺癌外,几乎完全没有经典的激活EGFR突变-外显子19缺失和外显子21 L858R突变。因此,对谱系依赖性和谱系存活癌基因的理解可能仍然为肿瘤恶性转化提供重要的机制见解,从而最终确定进一步的治疗脆弱性。

Malignant pleural mesothelioma (MPM) is a rare, aggressive cancer of the lung lining that is predominantly associated with occupational exposure to asbestos. MPM is responsible for thousands of deaths worldwide every year, with the median survival of MPM of 8–14 months. There are limited biomarkers available in the clinic to effectively diagnose MPM, an invasive biopsy procedure is usually required to provide a definitive diagnosis. Due to the long latency period associated with MPM disease presentation, the cancer is usually at an advanced stage at the time of diagnosis where treatment options are largely ineffective at controlling disease progression. Previous MPM-based pre-clinical studies have made significant strides in determining the exact molecular mechanisms associated with asbestos carcinogenesis. Exploring less invasive blood-based biomarkers and treatment strategies involving targeted therapy, immunotherapy, and virotherapy is particularly important. Research in these areas is of crucial importance in relation to improving the rate of novel diagnostic biomarkers and treatment strategies progressing through to clinical trials and ultimately into the clinical setting. This review comprehensively summarises both previous and current pre-clinical research developments that have specifically contributed to an improved understanding of MPM disease biology, and the development of novel diagnostic biomarkers and treatment strategies.
恶性胸膜间皮瘤(MPM)是一种罕见的侵袭性肺衬里癌症,主要与石棉的职业暴露有关。MPM每年导致全球数千人死亡,MPM的中位生存期为8-14个月。临床上可用于有效诊断MPM的生物标志物有限,通常需要侵入性活检程序来提供明确的诊断。由于MPM疾病表现的潜伏期较长,癌症在诊断时通常处于晚期,治疗方案在控制疾病进展方面基本无效。先前基于MPM的临床前研究在确定石棉致癌的确切分子机制方面取得了重大进展。探索侵入性较小的血液生物标志物和治疗策略,包括靶向治疗、免疫疗法和病毒治疗,尤其重要。这些领域的研究对于提高新的诊断生物标志物和治疗策略进入临床试验并最终进入临床环境的比率至关重要。这篇综述全面总结了以前和现在的临床前研究进展,这些进展特别有助于提高对MPM疾病生物学的理解,以及开发新的诊断生物标志物和治疗策略。

Objective: The combination of docetaxel (DTX) with Laser-Activated NanoTherapy (LANT), as a treatment for head and neck cancer (HNC) may enhance the therapeutic efficacy of lower doses of DTX, thereby minimizing the effective dosage, side effects and treatment times. Material and methods: Three HNSCC cell lines, Detroit 562, FaDu, and CAL 27, were treated with four combinations of DTX + LANT to evaluate DTX dose reduction and cell viability. Results: The 1 nM DTX + 5 nM LANT combination was the most effective treatment, increasing cell death over its corresponding DTX monotreatment with approximately 86.6%, 80.7%, and 92.1% cell death for Detroit 562, FaDu, and CAL 27, respectively. In Detroit 562, the 1 nM DTX + 5 nM LANT combination treatment resulted in the highest percentage of DTX dose reduction at 84.6%; in FaDu and CAL 27, the 0.5 nM DTX + 5 nM LANT combination treatment resulted in the highest percentage of DTX dose reduction at 78.2% and 82.4%, respectively. Conclusion: LANT may increase the therapeutic efficacy of DTX at significantly lower doses, which could improve patient outcomes.

BACKGROUND: Glioblastoma (GBM) is driven by various genomic alterations. Next-generation sequencing (NGS) could yield targetable alterations that might impact outcomes. The goal of this study was to describe how NGS can inform targeted therapy (TT) in this patient population. METHODS: The medical records of patients with a diagnosis of GBM from 2017 to 2019 were reviewed. Records of patients with recurrent GBM and genomic alterations were evaluated. Objective response rates and disease control rates were determined. RESULTS: A total of 87 patients with GBM underwent NGS. Forty percent (n = 35) were considered to have actionable alterations. Of these 35, 40% (n = 14) had their treatment changed due to the alteration. The objective response rate (ORR) of this population was 43%. The disease control rate (DCR) was 100%. The absolute mean decrease in contrast-enhancing disease was 50.7% (95% CI 34.8–66.6). CONCLUSION: NGS for GBM, particularly in the recurrent setting, yields a high rate of actionable alterations. We observed a high ORR and DCR, reflecting the value of NGS when deciding on therapies to match genomic alterations. In conclusion, patient selection and the availability of NGS might impact outcomes in select patients with recurrent GBM.
背景:胶质母细胞瘤(GBM)是由各种基因组改变驱动的。下一代测序(NGS)可以产生可能影响结果的有针对性的改变。本研究的目的是描述NGS如何为该患者群体的靶向治疗(TT)提供信息。方法:回顾2017年至2019年诊断为GBM的患者的病历。评估复发性GBM患者的记录和基因组改变。确定了客观反应率和疾病控制率。结果:共有87例GBM患者接受了NGS。40%(n=35)被认为有可操作的改变。在这35名患者中,40%(n=14)的治疗因改变而改变。该人群的客观有效率(ORR)为43%。疾病控制率(DCR)为100%。造影剂增强性疾病的绝对平均下降率为50.7%(95%CI 34.8-66.6)。结论:GBM的NGS,特别是在复发情况下,产生可操作的改变的比率很高。我们观察到高ORR和DCR,反映了NGS在决定与基因组改变相匹配的治疗方法时的价值。总之,患者的选择和NGS的可用性可能会影响复发性GBM患者的预后。

Purpose: Glioblastoma is one of the most aggressive and incurable brain tumors whose progression is driven in part by a small sub population of cells termed as glioblastoma stem cells responsible for the tumor’s low therapy efficacy. Hypoxia, a common phenomenon in glioblastoma also promotes the maintenance and the expansion of the stem cell population whose survival is aided by miRNAs. Methods: GBM stem-like cells cultures were isolated and the relationship between the microenvironments and the in vitro “stemness” of the cells was investigated by evaluating the expression of miRNAs and selected genes. Results: We found miR-128a-3p, 34-5p and 181a-3p to be down-regulated while miR-17-5p and miR-221-3p to be up-regulated in the stem-like cells. When a comparison was made between the stem-like cells cultured under normoxia and hypoxia, a fold down-regulation difference of 3.5 to 5, 2 to 5 and 2 to 4 for miR-34-5p, 128a-3p and 181a-3p was observed respectively and a fold upreulation of 3.5 to 4 and 2.5 to 4 was observed for miR-221-3p and 17-5p respectively. There was an increased expression of HIF-1/2, SOX2, OCT4, VEGF, GLUT-1, BCL2 and survivin under hypoxia. Conclusion: Hypoxia enhanced the expression of several tumor stem cell signature genes, involved in the regulation of stemness, metabolism, angiogenesis and anti-apoptotic property. Most importantly, the miRNA dysregulation in the stem-like cell population adds another layer of gene expression associated with gliomagenesis and maintenance of CSC pointing to new signaling mechanisms whose disruption can be used to successfully target this crucial subpopulation.
目的:胶质母细胞瘤是最具侵袭性和不可治愈的脑肿瘤之一,其进展部分是由被称为胶质母细胞瘤干细胞的一小群细胞驱动的,这导致了肿瘤的低治疗效果。缺氧是胶质母细胞瘤的一种常见现象,它也促进了干细胞群的维持和扩大,而干细胞群的生存是由mirna辅助的。方法:分离培养GBM干细胞样细胞,通过评价微环境与细胞体外“干性”之间的microrna表达及相关基因的表达,研究微环境与细胞体外“干性”的关系。结果:我们发现miR-128a-3p、34-5p和181a-3p在干细胞中下调,miR-17-5p和miR-221-3p上调。将常氧培养的干细胞与缺氧培养的干细胞进行比较,miR-34-5p、128a-3p和181a-3p分别下调3.5倍至5倍、2倍至5倍和2倍至4倍,miR-221-3p和17-5p分别上调3.5倍至4倍和2.5倍至4倍。低氧条件下HIF-1/2、SOX2、OCT4、VEGF、GLUT-1、BCL2、survivin表达升高。结论:缺氧可增强肿瘤干细胞特征基因的表达,参与肿瘤干细胞的干性、代谢、血管生成和抗凋亡的调控。最重要的是,干细胞样细胞群中的miRNA失调增加了与胶质瘤形成和CSC维持相关的另一层基因表达,指出了新的信号机制,其破坏可用于成功靶向这一关键亚群。

The Impact of Immune Checkpoint-Inhibitors Therapy in Urinary Bladder Cancer 免疫检查点抑制剂治疗对癌症的影响
Pub Date : 2021-03-04 DOI: 10.3390/ONCO1010002

Bladder cancer (BC) is one of the most common cancers in the world. From an early age, it was observed that chronic inflammation is associated with conditions favorable to the development of tumors, as well as the tumor microenvironment. Moreover, regulating tumor progression also interferes with the therapy’s response. The interaction between the tumor and the immune system led to the development of new immune therapies, the immune checkpoint inhibitors. Immunotherapy has shown a better safety profile, survival, and tolerance compared to standard chemotherapy. This therapy offers an effective alternative to patients who are ineligible for cisplatin and patients with advanced disease progression after platinum-based therapy. The first immunotherapy approved for BC was intravesical instillation with Bacillus Calmette–Guérin, for tumors at early stages. Later, immunotherapy focused on immune checkpoint inhibitors, namely, anti-programmed cell death protein 1 (PD1), anti-programmed cell death protein ligand 1(PD-L1), and anti-antigen 4 associated with cytotoxic T cells (CTLA-4). Currently, five immune checkpoint inhibitors for advanced BC are approved by the Food and Drug Administration (FDA): Atezolizumab, Durvalumab, Avelumab, Pembrolizumab, and Nivolumab. This review addresses the correlation between inflammation, tumor microenvironment, and cancer; various studies regarding immune checkpoint inhibitors, either in monotherapy or in combination therapy, are also addressed.
癌症是世界上最常见的癌症之一。从小就观察到,慢性炎症与有利于肿瘤发展的条件以及肿瘤微环境有关。此外,调节肿瘤进展也会干扰治疗的反应。肿瘤和免疫系统之间的相互作用导致了新的免疫疗法——免疫检查点抑制剂的发展。与标准化疗相比,免疫治疗显示出更好的安全性、生存率和耐受性。这种疗法为不符合顺铂条件的患者和铂类药物治疗后疾病进展晚期的患者提供了一种有效的替代方案。第一个被批准用于BC的免疫疗法是膀胱内滴注Calmette–Guérin芽孢杆菌,用于早期肿瘤。后来,免疫疗法专注于免疫检查点抑制剂,即抗程序性细胞死亡蛋白1(PD1)、抗程序性死亡蛋白配体1(PD-L1)和与细胞毒性T细胞相关的抗抗原4(CTLA-4)。目前,美国食品药品监督管理局(FDA)批准了五种用于晚期BC的免疫检查点抑制剂:阿替佐利珠单抗、杜伐单抗、阿韦鲁单抗、Pembrolizumab和Nivolumab。这篇综述阐述了炎症、肿瘤微环境和癌症之间的相关性;关于免疫检查点抑制剂的各种研究,无论是单药治疗还是联合治疗,也被提及。

From an early age, it was observed that chronic inflammation is associated with conditions favorable to the development of tumors, as well as the tumor microenvironment. Moreover, regulating tumor progression also interferes with the therapy’s response. The interaction between the tumor and the immune system led to the development of new immune therapies, the immune checkpoint inhibitors. Immunotherapy has shown a better safety profile, survival, and tolerance compared to standard chemotherapy. This therapy offers an effective alternative to patients who are ineligible for cisplatin and patients with advanced disease progression after platinum-based therapy. The first immunotherapy approved for BC was intravesical instillation with Bacillus Calmette–Guérin, for tumors at early stages. Later, immunotherapy focused on immune checkpoint inhibitors, namely, anti-programmed cell death protein 1 (PD1), anti-programmed cell death protein ligand 1(PD-L1), and anti-antigen 4 associated with cytotoxic T cells (CTLA-4). Currently, five immune checkpoint inhibitors for advanced BC are approved by the Food and Drug Administration (FDA): Atezolizumab, Durvalumab, Avelumab, Pembrolizumab, and Nivolumab.
