鼠mPC-1基因的克隆与特性分析

为深入研究人前列腺癌相关基因PC-1的生物功能和进化保守状况,从小鼠肾脏中克隆了全长cDNA序列,命名为mPC-1（GenBank Acc No.AY048852）.mPC-1基因cDNA全长为2 193 bp,主要定位于小鼠染色体3A1-A2区域.mPC-1基因最大开放阅读框编码的蛋白质由224个氨基酸组成,与人PC-1蛋白编码区存在82%的序列一致性,含有coiled-coil结构域和PEST结构域.生物信息学分析表明,由6个外显子组成的mPC-1基因与mD52高度同源,其中,第一外显子代表该基因的特异性序列,实验证据显示mPC-1基因具有自己的启动子,推测mPC-1与小鼠mD52可能是重叠基因.对小鼠20种组织器官和不同发育阶段的胚胎组织cDNA的RT-PCR检测证实,该基因主要在前列腺、肾和眼组织中表达,在胃和平滑肌中有少量表达,在其他组织中表达很弱或不表达.而mD52基因则几乎广泛存在于小鼠的各个组织器官中,因此,两个基因虽然序列上高度重叠却是独立调控的.综上所述,mPC-1基因可能是一个与人PC-1基因结构功能类似的新基因.

Mstn基因干扰通过上调基因Cpt1b促进肌间脂肪的β氧化

肌生长抑制素(myostatin,Mstn)也被称为生长/分化因子-8(GDF-8)。敲减或敲除Mstn基因可促进肌肉发育、降低脂肪含量。本研究利用RNA干扰技术制备Mstn干扰小鼠,随后对其骨骼肌形态、骨骼肌甘油三酯(triglyceride,TG)含量、脂肪酸组成及含量进行了分析。结果显示,与对照组相比,Mstn干扰小鼠肌肉中Mstn的表达减少。小鼠骨骼肌肌纤维的横截面积显著增大,而TG含量显著降低,n-3/n-6和不饱和/饱和脂肪酸比值显著升高。通过实时荧光定量PCR检测脂肪酸代谢相关基因的表达,结果表明脂肪酸分解和转运相关基因表达上调,而脂肪酸合成相关基因表达下调。在这些基因中,与β氧化相关的基因Cpt1b的上调尤为明显。对骨骼肌中CPT1的酶活性进行了检测,结果与基因表达情况一致。为探讨其进一步作用机理,通过染色质免疫沉淀实验发现,Mstn基因下游转录因子SMAD3可与Cpt1b基因的启动子直接结合。上述结果表明,Mstn敲减后主要通过调控其下游转录因子SMAD3与Cpt1b基因启动子的结合,上调Cpt1b的表达,从而促进肌内脂肪酸的β氧化代谢。

Astragalar morphology of late Eocene anthropoids from the Fayum Depression (Egypt) and the origin of catarrhine primates

The phylogenetic relationships of the late Eocene anthropoids Catopithecus browni and Proteopithecus sylviae are currently a matter of debate, with opinion divided as to whether these taxa are stem or crown anthropoids. The phylogenetic position of Catopithecus is of particular interest, for, unlike the highly generalized genus Proteopithecus, this taxon shares apomorphic dental and postcranial features with more derived undoubted catarrhines that appear in the same region 1-2 Ma later. If these apomorphies are homologous and Catopithecus is a stem catarrhine, the unique combination of plesiomorphic and apomorphic features preserved in this anthropoid would have important implications for our understanding of the crown anthropoid morphotype and the pattern of morphological character transformations that occurred during the early phases of stem catarrhine evolution.Well-preserved astragali referrable to Proteopithecus, Catopithecus, and the undoubted early Oligocene stem catarrhine Aegyptopithecus have provided additional morphological evidence that allows us to further evaluate competing hypotheses of interrelationships among Eocene-Oligocene Afro-Arabian anthropoids. Qualitative observations and multivariate morphometric analyses reveal that the astragalar morphology of Proteopithecus is very similar to that of early Oligocene parapithecids and living and extinct small-bodied platyrrhines, and strengthens the hypothesis that the morphological pattern shared by these taxa is primitive within crown Anthropoidea. In contrast, Catopithecus departs markedly from the predicted crown anthropoid astragalar morphotype and shares a number of apomorphic features (e.g., deep cotylar fossa, laterally projecting fibular facet, trochlear asymmetry, mediolaterally wide astragalar head) with Aegyptopithecus and Miocene-Recent catarrhines. The evidence from the astragalus complements other independent data from the dentition, humerus and femur of Catopithecus that support this taxon's stem catarrhine status, and we continue to maintain that oligopithecines are stem catarrhines that constitute the sister group of a clade containing propliopithecines and Miocene-Recent catarrhines.

scabrous Modifies Epithelial Cell Adhesion and Extends the Range of Lateral Signalling during Development of the Spaced Bristle Pattern in Drosophila

The role of scabrous (sca) in the evenly spaced bristle pattern of Drosophila is explored. Loss-of-function of sca results in development of an excess of bristles. Segregation of alternately spaced bristle precursors and epidermal cells from a group of equipotential cells relies on lateral inhibition mediated by Notch and Delta (Dl). In this process, presumptive bristle precursors inhibit the neural fate of neighbouring cells, causing them to adopt the epidermal fate. We show that Dl, a membrane-bound ligand for Notch, can inhibit adjacent cells, in direct contact with the precursor, in the absence of Sca. In contrast, inhibition of cells not adjacent to the precursor requires, in addition, Sca, a secreted molecule with a fibrinogen-related domain. Over-expression of Sca in a wild-type background, leads to increased spacing between bristles, suggesting that the range of signalling has been increased. scabrous acts nonautonomously, and we present evidence that, during bristle precursor segregation, Sca is required to maintain the normal adhesive properties of epithelial cells. The possible effects of such changes on the range of signalling are discussed. We also show that the sensory organ precursors extend numerous fine cytoplasmic extensions bearing Dl molecules, and speculate on a possible role for these structures during signalling.

Stratigraphy, artefact industries and hominid associations for Sterkfontein, member 5

A revised stratigraphy for the early hominid site of Sterkfontein (Gauteng Province, South Africa) reveals a complex distribution of infills in the main excavation area between 2.8 and 1.4 m.y.a, as well as deposits dating to the mid to late Pleistocene. New research now shows that the Member 4 australopithecine breccia (2.8-2.6 Ma) extends further west than was previously thought, while a late phase of Member 4 is recognized in a southern area. The artefact-bearing breccias were defined sedimentologically as Member 5, but one supposed part of these younger breccias, the StW 53 infill, lacks in situ stone tools, although it does appear to post-date 2.6 Ma when artefacts first appear in the archaeological record. The StW 53 hominid, previously referred to Homo habilis, is here argued to be Australopithecus. The first artefact-bearing breccia of Member 5 is the Oldowan Infill, estimated at 2-1.7 Ma. It occupies a restricted distribution in Member 5 east and contains an expedient, flake-based tool industry associated with a few fossils of Paranthropos robustus. An enlarged cave opening subsequently admitted one or more Early Acheulean infills associated in Member 5 west with Homo ergaster. The artefacts attest to a larger site accumulation between ca. 1.7 and 1.4 Ma, with more intensive use of quartzite over quartz and a subtle but important shift to large flakes and heavier-duty tools. The available information on palaeoenvironments is summarized, showing an overall change from tropical to sub-tropical gallery forest, forest fringe and woodland conditions in Member 4 to more open woodland and grassland habitats in the later units, but with suggestions of a wet localized topography in the Paranthropus -bearing Oldowan Infill.     

Essential amino acids of starch synthase IIa differentiate amylopectin structure and starch quality between <Emphasis Type="Italic">japonica</Emphasis> and <Emphasis Type="Italic">indica</Emphasis> rice varieties

Four amino acids were variable between the ‘active’ indica-type and ‘inactive’ japonica-type soluble starch synthase IIa (SSIIa) of rice plants; Glu-88 and Gly-604 in SSIIa of indica-cultivars IR36 and Kasalath were replaced by Asp-88 and Ser-604, respectively, in both japonica cultivars Nipponbare and Kinmaze SSIIa, whereas Val-737 and Leu-781 in indica SSIIa were replaced by Met-737 in cv. Nipponbare and Phe-781 in cv. Kinmaze SSIIa, respectively. The SSIIa gene fragments shuffling experiments revealed that Val-737 and Leu-781 are essential not only for the optimal SSIIa activity, but also for the capacity to synthesize indica-type amylopectin. Surprisingly, however, a combination of Phe-781 and Gly-604 could restore about 44% of the SSIIa activity provided that Val-737 was conserved. The introduction of the ‘active’ indica-type SSIIa gene enabled the japonica-type cv. Kinmaze to synthesize indica-type amylopectin. The starch in the transformed japonica rice plants exhibited gelatinization-resistant properties that are characteristic of indica-rice starch. Transformed lines expressing different levels of the IR36 SSIIa protein produced a variety of starches with amylopectin chain-length distribution patterns that correlated well with their onset temperatures of gelatinization. The present study confirmed that the SSIIa activity determines the type of amylopectin structure of rice starch to be either the typical indica-type or japonica-type, by playing a specific role in the synthesis of the long B₁ chains by elongating short A and B₁ chains, notwithstanding the presence of functional two additional SSII genes, a single SSI gene, two SSIII genes, and two SSIV genes in rice plants.
