MDR1基因+3435C/T基因型单核苷酸多态性对硼替佐咪治疗的多发性骨髓瘤预后的影响
Zhongguo shiyan zhenduanxue, 2013 目的探讨MDR1基因+3435C/T的单核苷酸多态性对硼替佐咪治疗的多发性骨髓瘤患者预后的影响。方法采用DNA测序方法检测MDR1基因+3435C/T的单核苷酸多态性;应用Kaplan-Meier来确认MDR1基因+3435C/T的单核苷酸多态性对硼替佐咪治疗/未治疗患者生存率的影响。结果 52.8%（n=47）的多发性骨髓瘤患者MDR1+3435位点的基因型为C/T,其余多发性骨髓瘤患者MDR1+3435位点的基因型均为T/T。MDR1+3435C/T基因型的患者的平均生存期为43.3月,而MDR1 ...

Veterinary Dermatology, Volume 37, Issue 1, Page 34-44, February 2026.Background: The chronic and multifactorial character of canine atopic dermatitis (cAD) often leads to poor disease control and treatment dissatisfaction. Environmental factors are likely to contribute to the disease development and may play a more important role than assumed previously.

The influence of zCep85 and zNek2 on the early embryonic development of zebrafish [PDF]
, 2016 zCep85是哺乳动物中心体结合蛋白Cep85在斑马鱼中的同源蛋白，其靠近C端的部分具有一个coil-coiled功能域，这是大部分中心体结合蛋白共有的结构。目前对zCep85的研究尚浅，本实验室早期报道显示，哺乳动物细胞中hCep85特异性地拮抗hNek2，使得细胞停滞于G2/M期。但是，我们对其在脊椎动物胚胎发育中的功能依然所知甚少。为了深入探究zCep85在发育中的作用，本课题以斑马鱼（Daniorerio）为动物模型从基因结构、表达谱、功能分析等方面研究了zCep85在胚胎发育中的作用。此外 ...

Veterinary Dermatology, Volume 37, Issue 1, Page 140-147, February 2026.Background: Normal hydration of the canine epidermis is imperative for cutaneous homeostasis. Xerosis may be encountered in canine atopic dermatitis and may be aggravated by topical antiseptics. Hypothesis and Objectives: To evaluate the hydrating properties and the safety of a spray (Sensiderm spray; MP Labo) when applied after shampooing healthy dogs

Effects of ApoE Isoforms Expression on Brain ApoE Lipidation and Amyloid-β Accumulation [PDF]
, 2015 在编码人三种不同apoE蛋白亚型（E2、E3和E4）的APOE等位基因（ε2、ε3和ε4）中，APOEε4等位基因是阿尔茨海默病（Alzheimer’sdisease，AD）最重要的遗传风险因子，APOEε2等位基因则具有保护作用。鉴于apoE蛋白亚型对基于调节apoE蛋白表达的AD治疗可能会有不同的影响，我们通过在人APOE基因定位替换（Targetedreplacement，TR）小鼠脑中过表达不同的人apoE亚型，研究脑中表达不同apoE亚型对apoE脂化和β-淀粉样蛋白（Amyloid-β，Aβ）

Preparation and characterization of chitosan and gelatin-siloxane nanoparticles as gene delivery system [PDF]
, 2006 基因治疗的提出为人类医学的发展提供了一种新的治疗手段。基因治疗载体是基因治疗中关键的因素之一。目前，基因治疗载体分为：病毒载体和非病毒载体。尽管病毒载体具有较高的转染效率，但易引起免疫反应和致癌作用；而非病毒载体如壳聚糖、明胶载体等具有良好生物相容性，但其粒径高达几百纳米至几个微米，不利于细胞对载体的摄取。因此，为了促进载体的细胞内化过程，本文旨在开发出粒径在100nm以下的新型壳聚糖、明胶-硅氧烷纳米颗粒，为基因治疗的发展提供新型的载体。本文的主要研究结果如下：1 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Nanozymes have attracted considerable attention in cancer therapy due to their adjustable enzyme activity and high catalytic efficiency. However, they still face a major challenge from tumor metastasis. In this work, endogenous/exogenous dual‐responsive bimetallic hollow PdRu (termed HPdRu) nanozymes were prepared.
