Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:HSF1A is a cell–permeable activator of heat shock transcription factor 1 (HSF1).IC50 & Target: HSF1[1]In Vitro: HSF1A protects cells from stress–induced apoptosis, binds TRiC subunits and inhibits TRiC activity without perturbation of ATP hydrolysis. Genetic inactivation or depletion of the TRiC complex results in human HSF1 activation and HSF1A inhibits the direct interaction between purified TRiC and HSF1 in vitro. Moreover, fluorescence anisotropy experiments using FITC coupled to HSF1A demonstrates that HSF1A–FITC binds to a purified Tcp1 subunit of TRiC with an affinity of approximately 600 nM. This is validated qualitatively via titration of purified Tcp1 into binding reactions containing 500 nM Biotin or HSF1A–Biotin [1]. Quantification bycounting the number of cell containing aggregates as a function of the total number of cells reveals that at HSF1A concentrations as low as 2 μM, a reduced number of aggregate–containing cells are observed. The fraction of cells containing aggregates continued to decrease in a dose–dependent manner such that pretreatment with 12 μM HSF1A resulta in ~20% of the cells exhibiting aggregates visible by fluorescence microscopy [2].In Vivo: HSF1A enhances HSF1 activity, stabilizes HSF1 expression and minimizes Doxorubicin (DOX)–induced cardiac damage. WKY rats are challenged with DOX (accumulated dose: 30 mg/kgw), and DOX combined with HSF1A (100 mg/kgw/day). Supplementation with HSF1A significantly elevates cardiac functions back to the levels of the control group. HSF1A has been shown to stimulate human HSF1 nuclear translocation, elevate protein chaperone expression and ameliorate protein misfolding and cell death in aneurodegenerative disease model. The echocardiographic results show that HSF1A also alleviates DOX–induced failures in cardiac function [3].PROTOCOL (Extracted from published papers and Only for reference)Kinase Assay:[1]Protein extracts are generated from mammalian, yeast and E. coli cultures using biotin–binding buffer (20 mM HEPES,5 mM MgCl 2, 1 mM EDTA, 100 mM KCl, 0.03% NP–40) supplemented with 1% Trition–X100 and protease inhibitors. Approximately 0.5mg of protein extract is incubated with 100 μM HSF1A–Biotin for 4 h at 4°C and HSF1A–Biotin associated proteins captured by with NeutrAvidin Agarose Resin. After washing in biotin binding buffer proteins are eluted using 50 μL biotin elution buffer (100 mM Tris,150 mM NaCl, 0.1 mM EDTA, 2 mM D–biotin), resolved on a 4–20% SDS–PAGE, and immunoblotted. For purified TRiC and Hsp70analyses, 5 nM protein is incubated in biotin–binding buffer+0.5% Triton X–100 with 100 μM biotin or 100 μM HSF1A–Biotin for 4 h at 4°C and captured with NeutrAvidin Resin. For NiNTA purified yeast Tcp1, different concentrations of Tcp1 0.5 μM, 1 mM, 2 mM, 3 mM and 4 mM in 25 mM Hepes pH 7.5, 150 mM NaCl are incubated with 0.5 μM Biotin or HSF1A–Biotin for 4 h at 4°C and captured with NeutrAvidin Resin [1].Cell Assay:[2]PC12 cells seeded into a 96–well plate (5×104 cells/well) are treated with increasing concentrations of HSF1A (2, 4, 8 andProduct Name:HSF1A Cat. No.:HY-103000CAS No.:1196723-93-9Molecular Formula:C21H19N3O2S2Molecular Weight:409.52Target:HSP Pathway:Cell Cycle/DNA Damage; Metabolic Enzyme/Protease Solubility:DMSO: ≥ 150 mg/mL12 μM) for 15 h, at which time httQ74–GFP expression is stimulated by incubation in the presence of 1 μg/mL Doxycycline for 5 d. Cell viability is assessed via the XTT viability assay[2].Animal Administration:[3]Rat[3]Ten–week–old Wistar Kyoto rats (WKY) are used. The rats are housed at a constant temperature (22°C) on a 12–h light/dark cycle with food and tap water. The animals are arranged into three groups: WKY rats (the control group), DOX rats and DOX rats treated with HSF1A. Each group contain five animals. The DOX group is injected with DOX (5 mg/kg) for 6 consecutive weeks intraperitoneal injection to achieve a cumulative dose of 30 mg/kg, which has been well documented to achieve cardiotoxicity. The small molecular HSF1 activator HSF1A (100 mg/kg/day) is injected intraperitoneally.References:[1]. Neef DW, et al.

非小细胞肺癌(non-small cell lung cancer,NSCLC)发病率占据肺癌的75%~80%。
肿瘤细胞进展快且易扩散转移,临床常采用手术、放化疗等进行治疗,但5年生存率低于60%[1-2]。
氧化应激是由活性氧(ROS)生成量增加所致,ROS积累可诱导肺癌细胞凋亡,清除ROS 可阻止癌细胞凋亡,即肺癌细胞存活依赖于癌细胞自身抗氧化能力[3]。
Kelch样环氧氯丙烷相关蛋白-1 (kelch-like epichlorohydrin-associated protein-1,Keap1)/核因子E2相关因子2(nuclear factor E2related factor 2,Nrf2)信号通路在癌症中发挥重要调控作用,氧化应激可激活Keap1,促使Keap1-Nrf2复合物裂解,Nrf2转移至细胞核内,可激活下游靶基因表达,参与肺癌发生发展过程[4]。
Nrf2可维持氧化还原稳态,ROS侵袭细胞时,Nrf2可进入细胞核,结合抗氧化反应元件(ARE)转录编码各种抗氧化蛋白、代谢酶基因,抑制氧化应激反应[5-6]。
目前氧化应激、Keap1/Nrf2信号通路在NSCLC发生过程中的机制尚未明确。
基于此,本研究尝试分析Keap1/Nrf2信号通路与临床病理参数、氧化应激指标的相关性,探讨其在NSCLC氧化应激机制中的作用,为临床研制新药提供参考依据。
1资料与方法1.1一般资料选取2017年4月至2020年4月郑州市第三人民医院收治的100例NSCLC患者为研究对象。
纳入标准:符合NSCLC诊断标准[7];术前未接受放化疗、免疫治疗者;预计生存期≥6个月;符合手术适应证、禁忌证;Karnofsky功能状态评分≥70分;签署知情同意书。
排除标准:合并凝血功能障碍、肝肾功能障碍、其他恶性肿瘤者;伴有急/慢性感染者;伴有精神疾病者;既往腹部相关外科手术史者。
所有患者均行肺癌根治性切除术,术中收集癌组织、癌旁组织(距离癌组织5cm范围内正常组织),其中男性63例,女性37例;年龄46~67岁,平均(56.32±3.16)岁;体质量指数(BMI)17~30kg/m2,平均(23.16±2.03)kg/m2;病理类型:鳞癌58例、腺癌42例;病理分级[8]:Ⅰ~Ⅱ级51例、Ⅲ级49例;T分期[9]:T1~T253例、T3~T447例;N分期:N055例、N1~N245例。
