To the Editor:Hyperuricemia,the second most common metabolic disease after diabetes mellitus in China,is characterized by the elevated serum uric concentration which is due to the overactive uric acid production or underexcretion.[1]Recent study supported the notion that hyperuricemia is implicated in renal tubular injury,subsequent tubulointerstitial fibrosis,and finally gouty nephropathy.[2]However,the lack of a suitable and stable mouse model to study hyperuricemia and gout nephropathy delays and limits the development of mechanism research and new *** understanding of the pathogenesis of hyperuricemia and gouty nephropathy has been largely hampered by a lack of preclinical animal models that reliably capture the characteristic phenotypes of hyperuricemia and gouty *** this study,we aimed to develop a novel mouse model for hyperuricemia and gouty nephropathy.

植物叶片中,表皮蜡质对植物的生长发育和适应外界环境起着重要作用。本研究针对拟南芥(Arabidopsis thaliana)已发表的蜡质相关基因信息,基于生物信息学的方法获得以甘蓝型油菜(Brassica napus)品种中双11号为参考的10个蜡质相关基因的44个拷贝序列。然后,以在抽薹期前后叶片蜡质差异明显的3对自然突变的甘蓝型油菜(L1050,P144和W481)为材料,利用同源克隆的方法获得这些拷贝成员在3对甘蓝型油菜中的核苷酸和蛋白序列,通过多重比对分析发现,甘蓝型油菜蜡质基因(wax inducer 2,WIN2)家族中的Bn WIN2C01在核苷酸与氨基酸水平上均存在稳定的突变位点。利用q RT-PCR分析基因Bn WIN2C01在甘蓝型油菜突变体材料抽薹期前后叶片中的表达情况,结果表明该基因在表皮蜡质合成前后的叶片中达到极显著差异水平(P<0.01),说明Bn WIN2C01基因的特异性表达可能影响了叶片蜡质的合成。本研究将有助于阐明叶表皮蜡质形成过程的分子机理,为提高油菜抗逆性提供一定的参考依据。

为明确甘蓝型油菜显性核不育两型系D3AB的花器官形态差异和不育材料D3A的花药败育时期与特点,并为进一步研究雄性不育机理奠定基础,分别对D3A与D3B不同时期的花蕾进行了形态学观察及细胞学研究.首先通过体视镜观察发现,D3A与D3B外观形态无明显差异,均能正常开花,且在雄蕊发育早期均表现正常,后期D3A雄蕊退化萎缩,花粉囊不能正常开裂;不育材料D3A子房柱头发育速度稍快于D3B.通过扫描电镜观察发现,D3A早期花药基部开始皱缩,表皮细胞排列紧密.随着花蕾发育,D3A花粉囊壁表皮细胞逐渐萎缩,最终塌陷且药室不能正常开裂释放花粉;D3B花粉囊始终呈现出紧致饱满状态,花药正常开裂,同时释放出大量成熟花粉粒.通过石蜡切片观察发现,不育材料D3A和可育材料D3B在花蕾发育早期,都能形成花粉母细胞,但与D3B相比,D3A花粉母细胞结构松散,且绒毡层已开始呈现液泡化状态;进入四分体时期,不育材料D3A的花粉囊中观察到高度液泡化的绒毡层细胞,且无四分体结构出现.实验结果表明:绒毡层细胞提前发生了降解而未向分泌型转化,使四分体时期丧失了发育过程中所必需的营养物质,从而不能形成小孢子并发育为成熟的花粉粒进行释放,因此认为D3A的败育属于绒毡层发育异常类型.
