The transcription of WRN1 mRNA was down-regulated by natural- and dark-induced senescence. But it was not senile-tissue-specific. As the two key histidine residues were replaced, WRN1 may not be active as RNase. Southern blotting analysis showed that WRN1 exists as one of a small gene family in common wheat genome.展开更多

The heterosis protects the genetic diversity and makes the population owning a stronger self-control and evolution potential by improving the hetemzygote＇s fithess so as not to wash out different types of genes. It deepens Darwin＇s thoughts of individual section by making the individual fitness consonant with population fitness.展开更多

However,unlike their low-grade counterparts, high-grade gastric MALT lymphomas may progress rapidly if unresponsive to H pylori eradication. It is mandatory to identify markers that may predict the H pylori-dependent status of these tumors. Proliferation of MALT lymphoma cells depends on cognate help and cell-to-cell contact of H pylori- spedfic intratumoral T-cells. To examine whether the expression of co-stimulatory marker CD86 （B7.2） and the infiltration of CD56 （＋） natural killer （NK） cells can be useful markers to predict Hpylori-dependent status of high-grade gastric MALT iymphoma.METHODS： Lymphoma biopsies from 26 patients who had participated in a prospective study of Hpylori-eradication for stage IE high-grade gastric MALT lymphomas were evaluated. Tumors that resolved to Wotherspoon grade Ⅱ or less alter H pylori eradication were dassified as H pylori-dependent; others were dassified as H pylori-dependent.The infiltration of NK cells and the expression of CD86 in pre-treatment paraffin-embedded lymphoma tissues were determined by immunohistochemistry. RESULTS： There were 16 H pylori-dependent and 10 H pylori-independent cases. CD86 expression was detected in 11 （68.8%） of 16 H pylori-dependent cases but in none of 10 H pylori-independent cases （P = 0.001）.H pylori-dependent high-grade gastric MALT lymphomas contained significantly higher numbers of CD56 （＋） NK cells than H pylori-independent cases （2.8±1.4% vs 1.1±0.8%, P = 0.003）. CD86 positive MALT lymphomas also showed significantly increased infiltration of CD56 （＋） NK cells compared to CD86-negative cases （2.9±1.1% vs 1.4±1.3%; P= 0.005）.CONCLUSION： These results suggest that the expression of co-stimulatory marker CD86 and the increased infiltration of NK cells are associated with Hpylori-dependent state of early-stage high-grade gastric MALT lymphomas.展开更多

Compelling evidence points to an evolutionary important role of HSPs and a strict evolutionary control of these proteins as a balance between benefits and costs. While there is a great potential for using HSP expression for detecting natural adaptation and exposure to stress in natural populations, some obstacles and key issues await investigation. From an ecological perspective these key issues needs to be resolved in order to fully appreciate the complex responses and adaptations to stress and to increase our understanding of HSPs and other molecular chaperones for stress adaptation and potential use as biomarkers. Here, the current knowledge and understanding of HSPs is reviewed and a number of key issues including the interpretation of elevated HSP levels, the complications of extrapolating between laboratory and field conditions, the effects of choice of traits and methodology and the larger intra-and extracellular networks of interactions that HSPs participate in are discussed [Current Zoology 56 （6）： 703-713, 2010].展开更多
