[Abstract]  Polyethylene glycol calcium (PEG-Ca2+)-mediated transfection allows rapid and efficient examination to analyze diverse cellular functions of genes of interest. In plant cells, macromolecules, such as DNA, RNA and protein, are delivered into protoplasts derived from somatic tissues or calli via PEG-Ca2+ transfection. To broaden and develop the scope of investigations using plant gametes and zygotes, a procedure for direct delivery of macromolecules into these cells has recently been established using PEG-Ca2+ transfection. This PEG-Ca2+-mediated delivery into rice egg cells/zygotes consists of four microtechniques, (i) isolation of gametes, (ii) production of zygotes by electrofusion of gametes, (iii) PEG-Ca2+-mediated delivery of ...

[Abstract]  Ex vivo culture assays of biopsy specimens are advantageous for the experimental evaluation of human circadian characteristics. We developed a simple and non-invasive experimental evaluation method for monitoring the expression of circadian clock genes in an ex vivo culture assay using human hair follicles. This method imposes little burden on subjects. This assay is useful for validating correlations between circadian characteristics in hair follicles and intrinsic characteristics observed in physiological and behavioral studies. While they should be further validated, this ex vivo method constitutes a useful tool for estimating in vivo circadian characteristics. [摘要]  [摘要] 活检标本的体外培养测定法有利于人体昼夜节律特征的实验评估。我们开发了一种简单而无创的实验评估方法,用于监测人发体外培养法中昼夜节律基因的表达follicles.This方法强加subjects.This测定法是用于验证昼夜CH之间的相关性有用的小负担在毛囊和固有特性在生理和行为studies.While观察aracteristics它们应该被进一步验证,该离体方法用于小的有用工具体内估计 昼夜节律特征。

[背景] 活的生物体表现出在生理和行为的昼夜节律由生物钟驱动(杨和Kay,2001)。该昼夜发条由转录的细胞自主性和时钟基因驱动的负反馈环路(邓拉普,1999 )。在哺乳动物中,转录因子BMAL1和CLOCK 通过E-box元件激活时钟和与时钟相关的基因(例如Period (Per )和Cryptochrome (Cry ))的转录.PER与有效的转录抑制剂CRY一起起作用负性调节这一复杂(里珀特织女,2002年)。在体内评估个体的内在节律特点在人类,要么以恒定的例行或强制去同步化协议,价格昂贵,耗力。因此,评估利用离体培养试验中要估计体内的昼夜节律特征可能具有重要的优势。例如,一些研究已经结束,n个外周细胞反映了个体的昼夜节律偏好,称为计时型(Brown 等人,2005; Hida 等人,2013 ...

[Abstract]  Organisms have developed many protective systems to reduce the toxicity from heavy metals. The nematode Caenorhabditis elegans has been widely used to determine the protective mechanisms against heavy metals. Responses against heavy metals can be monitored by expression of reporter genes, while sensitivity can be determined by quantifying growth or survival rate following exposure to heavy metals. [摘要]  生物开发了许多保护系统,以减少重金属的毒性。线虫秀丽隐杆线虫已广泛用于确定重金属的保护机制。可以通过报告基因的表达来监测对重金属的反应,而敏感性可以通过量化暴露于重金属后的生长或存活率来确定。

背景 一些重金属如砷,镉和汞已知对包括人类在内的大多数生物有害(Valko et al。,2005)。为了降低这些金属的毒性,生物开发出各种保护系统。线虫秀丽隐杆线虫已被用于了解重金属的保护机制。以前的研究表明,许多基因,如解毒酶,转录因子和信号传导因子都参与了该生物体中重金属的保护(Broeks et al。,1996; Mizuno et al。 ,2004; Inoue等人,2005; Schwartz等人,2010)。除了测量报告基因表达外,生存力和生长的测定通常用于监测重金属在C中的影响。线虫。在本协议中,我们描述了使用C测定砷,铜和镉的方法。线虫。
