ARHI interacts with TR3 and activates apoptosis and autophagy via mitochondrial signaling pathway in human gastric cancer cells [PDF]
, 2015 ARHI是一个母源性抑癌印记基因，属ras/rap超家族成员，在人类多种正常组织中高表达，而在人卵巢癌、乳腺癌、胰腺癌、肝癌等多种肿瘤中表达明显下调或缺失。ARHI可以调节细胞周期控制细胞增殖，并通过多种途径参与细胞的凋亡和自噬。核孤儿受体TR3属于类固醇/甲状腺受体超家族，几乎参与人体所有组织和器官的功能调节。TR3作为转录因子调控基因表达，参与细胞增殖和凋亡调控过程，还可以作为功能蛋白，通过蛋白亚细胞定位、蛋白相互作用和蛋白修饰等途径发挥作用。本课题研究两个蛋白是否结合及其结合模式 ...

Veterinary Dermatology, Volume 36, Issue 6, Page 862-869, December 2025.ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...

外源性表达VEGF165b对人膀胱癌裸鼠移植瘤生长影响的研究
Zhongguo shiyan zhenduanxue, 2014 目的建立人膀胱癌T24细胞裸鼠移植瘤模型,探讨外源性表达VEGF165b对其生长的影响及其机制。方法分别移植未转染和转染VEGF165b表达载体的人膀胱癌T24细胞到裸鼠膀胱内,28d使处死动物,称量肿瘤重量,测定肿瘤体积。Western blot法检测肿瘤VEGF165b、p-VEGFR2、AKT、p-AKT蛋白表达。结果转染pcDNA-VEGF165b组肿瘤重量和体积与未转染组和转染pcDNA3.0组相比明显降低（P0.05）。Western blot结果显示,转染pcDNA ...

The structure and function of WBP2 in Glioma [PDF]
, 2016 脑白质疏松症(Leukoariaosis，LA)在中年及老年人中逐渐普遍，随着年龄的 增长，患者表现出认知功能障碍、运动功能障碍、痴呆、抑郁和中风等，这在很 大程度上加重了公共医疗的负担。但是目前人们对脑白质疏松症的病理生理机制 所知甚少。 分子生物学的飞速发展为科学家们研究疾病的致病基因及发病机制提供了 更好的条件和更广阔的前景。文献报道WBP2基因SNP位点的突变与LA的发 病相关。研究发现WBP2也参与了乳腺癌的发生，因此，推测WBP2与神经疾 病和肿瘤的发生均密切相关 ...

miRNA-17~92 Inhibits Colorectal Cancer Progression by Targeting Angiogenesis [PDF]
, 2015 miRNA中的miR-17~92簇在包括结直肠癌（Colorectalcancer，CRC）等人类癌症中广泛表达。已有的研究表明miR-17~92在某些肿瘤模型中可促进肿瘤发生和癌组织血管生成。然而，其在CRC发生和进展中的作用仍然未知。在本研究中，我们意外发现，在用氧化偶氮甲烷（AOM）和右旋糖酐硫酸钠（DSS）诱导的CRC动物模型中，大肠、小肠上皮细胞过表达miR-17~92的转基因小鼠可见肿瘤体积变小、肿瘤血管减少。进一步研究发现，miR-17 ...

Hydrocortisone Aceponate for Chronic Otitis: Long‐Term Efficacy
Veterinary Dermatology, Volume 36, Issue 6, Page 870-878, December 2025.Effective management of otitis externa (OE) requires addressing all contributing factors to prevent chronicity and recurrence. Evidence on the long‐term efficacy of topical corticosteroids in preventing recurrence and secondary infections remains limited. This retrospective noncontrolled study evaluated the efficacy of hydrocortisone aceponate (HCA) in
