Duchenne肌肉营养不良(DMD)是一种X连锁疾病,是由DMD基因突变引起的,导致逐渐浪费肌肉和无力。目前无法治愈DMD。BL10-MDX小鼠是临床前DMD研究中最常用的模型,但与DMD患者相比,它表现出温和的疾病表型,从而限制了研究的可转换性。较新的D2-MDX小鼠在很小的时候就具有更严重的表型,并且可以更好地概括人类疾病。将这些小鼠模型与定量RT-PCR,稳定且可靠的参考基因进行比较是必不可少的。We aimed to evaluate the stability and reliability of a panel of nine candidate reference genes ( Actb, Ap3d1, Gapdh, Hmbs, Htatsf1, Pak1ip1, Rpl13a, Sdha and Zfp91 ) in the gastrocnemius, diaphragm and heart of mice from both strains and their corresponding wild types aged 4 to 52 weeks.使用Genorm,最佳门将,三角肌和Normfinder分析数据。我们发现HTATSF1,PAK1IP1和ZFP91是合适的参考基因,用于在营养不良和健康小鼠中基因表达的标准化,无论组织类型或年龄如何。在我们的手中,ACTB,GAPDH和RPL13A不适合作为参考基因,表现出组织,年龄或疾病特定的表达变化。这项研究强调了选择合适的参考基因的重要性,因为它们的稳定性在特定的实验设置之间可能有所不同。
Alzheimer disease (AD) accounts for 60 – 70% of dementia cases. Given the seriousness of the disease and continual increase in patient numbers, developing effective therapies to treat AD has become urgent. Presently, the drugs available for AD treatment, including cholinesterase inhibitors and an antagonist of the N-methyl-D-aspartate receptor, can only inhibit dementia symptoms for a limited period of time but cannot stop or reverse disease progression. On the basis of the amyloid hypothesis, many global drug companies have conducted many clinical trials on amyloid clearing therapy but without success. Thus, the amyloid hypothesis may not be completely feasible. The number of anti-amyloid trials decreased in 2019, which might be a turning point. An in-depth and comprehensive understanding of the contribution of amyloid beta and other factors of AD is crucial for developing novel pharmacotherapies. In ongoing clinical trials, researchers have developed and are testing several possible interventions aimed at various targets, including anti-amyloid and anti-tau interventions, neurotransmitter modification, anti-neuroinflammation and neuroprotection interventions, and cognitive enhancement, and interventions to relieve behavioral psychological symptoms. In this article, we present the current state of clinical trials for AD at clinicaltrials.gov . We reviewed the underlying mechanisms of these trials, tried to understand the reason why prior clinical trials failed, and analyzed the future trend of AD clinical trials.

摘要:胶质母细胞瘤(GBM)的中位患者生存期为15个月,仍然是死去的恶性肿瘤之一。尽管付出了巨大的努力,但由于各种耐药机制,治疗方案无法延长GBM患者的总生存率。趋化因子信号作为肿瘤微环境的一部分,在神经胶质作用,增殖,新生血管形成,转移和肿瘤进展中起关键作用。In this review, we aimed to investigate novel therapeutic approaches tar- geting various chemokine axes, including CXCR2/CXCL2/IL-8, CXCR3/CXCL4/CXCL9/CXCL10, CXCR4/CXCR7/CXCL12, CXCR6/CXCL16, CCR2/CCL2, CCR5/CCL5 and GBM的临床前和临床研究中的CX3CR1/CX3CL1。,我们将靶向疗法作为单疗法,与护理标准相结合,抗血管生成治疗以及免疫疗法。我们发现临床前和临床研究中有许多拮抗剂,抗体,细胞和疫苗的治疗方法。此外,有针对性的疗法与其他已建立的治疗应用结合使用了最高的效率。新颖的趋化因子靶向therapies主要在临床前模型中进行了检查。但是,临床应用是吉祥的。因此,广泛研究最近开发的临床前方法至关重要。应在临床研究中研究有希望的临床前应用,以创建新的治疗方案并克服对GBM治疗的耐药性。
血小板功能可以通过癌细胞来修饰以支持肿瘤的生长,从而导致微弱止血平衡的改变。癌细胞和血小板相互作用是特鲁索综合征的主要支柱之一:一种副肿瘤综合征,具有重复和迁移的血小板症发作。总的来说,这导致了癌症患者血栓形成事件的四倍风险,而癌症患者的预后不佳。我们先前证明了抗P2RY12药物在胰腺癌模型中抑制癌症相关的血栓形成和肿瘤转移的形成。Here, we aimed to (1) compare the effects of aspirin and clopidogrel on pancreatic cancer prevention, (2) characterize the effects of clopidogrel (platelet P2RY12 inhibitor) on cancer-associated thrombosis and cancer growth in vivo , (3) determine the effect of P2RY12 across different digestive-tract cancers in vitro , and (4) analyze the expression pattern of P2RY12在两种影响消化系统的癌症类型中。氯吡格雷治疗与阿司匹林治疗相比,原发性肿瘤较小,转移的生存率更高。氯吡格雷在我们的原位晚期癌小鼠模型中溶解自发的内源性血栓也比阿司匹林更有效。p2ry12表达给出胰腺腺癌的增殖优势。总而言之,我们提出了以下假设:氯吡格雷应进一步研究以靶向和预防曲索综合征。以及减少癌症的生长和扩散。但是,需要更多的研究来确定这些药物对癌症发展的含义途径和影响。
简介:肾衰竭是一种病理状况,其特征是代谢终产物的肾脏排泄受损。Objectives: The present study aimed to assess ghrelin hormone and certain biochemical parameters such as urea, creatinine, uric acid, albumin, total protein, alkaline phosphatase (ALP), triglycerides (TG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-c), low- density lipoprotein-cholesterol与健康受试者相比,血液透析患者血清中(LDL-C)和非常低密度的脂蛋白(VLDL)。患者和方法:在这项横断面研究中,从伊拉克巴格巴教学医院的IBN Sina透析中心(2022年5月至2022年10月),总共六十例血液透析的末期肾脏疾病患者入学。此外,在这项研究中,有30名健康的志愿者是对照对象。结果:结果表明,与对照组相比,血液透析患者的血清血清素水平显着降低(p <0.05)。值得注意的是,与对照组相比,患者的血清尿素,尿酸和肌酐水平升高(p <0.05)。此外,与对照组相比,患者的血清白蛋白水平也降低了(p <0.05)。但是,总蛋白质的水平没有在两组之间显示出任何显着差异(p> 0.05)。检测到血清生长素素和尿素之间的显着负相关(p <0.05)。结论:发现肾衰竭患者的生长素素水平显着降低。因此,慢性肾脏疾病患者肾脏不足的潜在预测因子降低。
抽象目的:染色体不稳定性(CIN)是癌症的标志,其特征是染色体的细胞对细胞变异性,在癌细胞群体中经常观察到,并且与预后不良,转移和治疗耐药性不佳有关。乳腺癌(BC)的特征是不稳定的核型,最近的报道表明CIN可能会影响BC对化疗方案的反应。然而,已经观察到极端CIN与改善结果之间的矛盾关联。Methods: This study aimed to 1) evaluate CIN levels and clonal heterogeneity (CH) in MCF7, ZR-751, MDA-MB468, BT474, and KPL4 BC cells treated with low doses of tamoxifen (TAM), docetaxel (DOC), doxorubicin (DOX), Herceptin (HT), and combined treatments (TAM/DOC,通过使用荧光原位杂交(FISH),TAM/DOX,TAM/HT,HT/DOC和HT/DOX)通过将鱼类的结果与细胞增殖进行比较,检查与治疗的响应相关性。结果:根据三个特征,中间CIN与药物敏感性有关:雌激素受体α(ERα)和HER2状态,癌细胞中的CIN水平以及治疗诱导的CIN。ERα +/HER2-具有中间CIN的细胞对紫杉烷(DOC)和蒽环类动物(DOX)的治疗敏感,而ERα - /HER2-,ERα +/HER2 +,ERα +/HER2 +,ERα-/HER2 +细胞具有中间型的抗性。结论:对BC中CIN和CH的更深入的了解可以帮助优化现有的治疗方案和/或支持改善癌症结局的新策略。关键词乳腺癌;染色体不稳定性;耐药性;鱼;克隆异质性
