对于Click-iT TUNEL for In Situ Apoptosis Detection实验,我应该在蛋白酶K中消化组织样品多久?
用于细胞凋亡Click-iT Plus TUNEL for In Situ Apoptosis Detection实验的组织切片应该多厚?
我们在5–20 µM 厚度的老鼠肠、肾脏、肝脏、心脏和结肠FFPE切片中验证了Click-iT Plus TUNEL for In Situ Apoptosis Detection实验
我能对组织样品使用初代Click-iT TUNEL实验试剂盒么?
初代Click-iT TUNEL实验试剂盒针对细胞培养样品优化,也可用于组织样品。我们建议对组织样品使用Click-iT Plus TUNEL for In Situ Apoptosis Detection实验试剂盒;用于组织的Click-iT Plus TUNEL for In Situ Apoptosis Detection实验试剂盒的实验方案针对组织样本优化。通过改进方案可以提高TdT酶进入多层细胞组织样品的效果。另外,相比于Click-iT Plus TUNEL试剂盒,我们发现初代Click-iT TUNEL试剂盒可能会在组织样品出现高度非特异性结合和点状染色。有一个增加组织透过性较好的方法是用蛋白酶K消化然后甲醛中再固定样品以取代去污剂透化作用步骤。Click-iT Plus TUNEL试剂盒手册第三部分的组织固定和透化作用方案可用于初代Click-iT TUNEL实验处理组织样品。胃蛋白酶和其他的蛋白水解酶同时也可用于提高组织透过性。
Usp9X Regulates Cell Death in Malignant Peripheral Nerve Sheath Tumors.
Authors:Bianchetti E, Bates SJ, Carroll SL, Siegelin MD, Roth KA,
Journal:Sci Rep
PubMed ID:30478285
'Malignant peripheral nerve sheath tumors (MPNSTs) are the leading cause of death in neurofibromatosis type 1 (NF1) patients. Current treatment modalities have been largely unsuccessful in improving MPNST patient survival, making the identification of new therapeutic targets urgent. In this study, we found that interference with Usp9X, a deubiquitinating enzyme ... More
Inhibition of Hedgehog signaling reprograms the dysfunctional immune microenvironment in breast cancer.
'Host responses to tumor cells include tumor suppressing or promoting mechanisms. We sought to detail the effect of Hedgehog (Hh) pathway inhibition on the composition of the mammary tumor immune portfolio. We hypothesized that Hh signaling mediates a crosstalk between breast cancer cells and macrophages that dictates alternative polarization of ... More
The structural atrophy of the aneurysm wall in secondary expanding aortic aneurysms with endoleak type II.
Authors:Menges AL, Busch A, Reutersberg B, Trenner M, Kath P, Chernogubova E, Maegdefessel L, Eckstein HH, Zimmermann A
Journal:J Vasc Surg
PubMed ID:30792063
'Abdominal aortic aneurysm (AAA) has an age-dependent prevalence of 2% to 11% and is a leading cause of death in men aged >65 years if not treated surgically. Today, endovascular aneurysm repair (EVAR) is performed in up to 80% of elective cases and 60% of ruptured cases. Although EVAR improves perioperative, ... More
Anti-tumor effect of cisplatin in human oral squamous cell carcinoma was enhanced by andrographolide via upregulation of phospho-p53 in vitro and in vivo.
'Oral squamous cell carcinoma is one of the most common neoplasm in the world. Despite the improvements in diagnosis and treatment, the outcome is still poor now. Thus, the development of novel therapeuticapproaches is needed. The aim of this study is to assess the synergistic anti-tumor effect of andrographolide with ... More
Synergistic anti-tumor efficacy of sorafenib and fluvastatin in hepatocellular carcinoma.
Authors:Cheng Y, Luo R, Zheng H, Wang B, Liu Y, Liu D, Chen J, Xu W, Li A, Zhu Y,
Journal:Oncotarget
PubMed ID:28423574
Drug resistance to sorafenib is common in patients with hepatocellular carcinoma(HCC). We examined the effects of a combination of sorafenib and fluvastatin on HCC using in vitro and in vivo models. The dual treatment induced apoptosis and reduced cellular viability in HCC more effectively than either drug alone. The combination ... More
