摘要： The invention disclosed a method for forming high aspect ratio patterning structure. Firstly, forming a dielectric film ashing stop layer, a first photoresist layer, a first hard mask layer and a second photoresist layer on a semiconductor substrate in turn. A second hard mask layer having a high etch selectivity ratio with the first photoresist layer is formed on top surface and sidewall of the pattern by utilizing a low temperature chemical vapor deposition process, which can be a protect for the pattern sidewall during the later etching process of the first photoresist layer. So, the cone-shaped or the bowling-shaped photoresist morphology caused by plasma bombardment can be avoided. Therefore, the problems of the insufficient of selectivity ratio, burrs at the edge of the pattern and larger critical dimension can be solved, and the implanted ions can be well distributed according to the design of the device.

摘要： The mechanism by which the high bone mass (HBM) mutation (G171V) of the Wnt coreceptor LRP5 regulates the canonical Wnt signaling was investigated. The mutation was previously shown to reduce Dkk protein-1-mediated antagonism, suggesting that the first YWTD repeat domain where G171 is located may be responsible for Dkk protein-mediated antagonism. However, we found that the third YWTD repeat, but not the first repeat domain, is required for DKK1-mediated antagonism. Instead, we found that the G171V mutation disrupted the interaction of LRP5 with Mesd, a chaperon protein for LRP5/6 that is required for the coreceptors' transport to cell surfaces, resulting in less LRP5 molecules on the cell surface. Although the reduction in the level of cell surface LRP5 molecules led to a reduction in Wnt signaling in a paracrine paradigm, the mutation did not appear to affect the activity of coexpressed Wnt in an autocrine paradigm. Together with the observation that osteoblast cells produce autocrine canonical Wnt, Wnt7b, and that osteocytes produce paracrine Dkk1, we believe that the G171V mutation may cause an increase in Wnt activity in osteoblasts by reducing the number of targets for paracrine Dkk1 to antagonize without affecting the activity of autocrine Wnt.
摘要翻译：研究了Wnt共同受体LRP5的高骨量（HBM）突变（G171V）调节规范Wnt信号传导的机制。以前显示突变可以降低Dkk蛋白-1介导的拮抗作用，这表明G171位于第一个YWTD重复结构域可能是Dkk蛋白介导的拮抗作用的原因。然而，我们发现第三个YWTD重复，但不是第一个重复结构域，是DKK1介导的拮抗作用所必需的。相反，我们发现G171V突变破坏了LRP5与Mesd的相互作用，Mesd是共受体转运到细胞表面所需的LRP5 / 6的伴侣蛋白，导致细胞表面上较少的LRP5分子。尽管细胞表面LRP5分子水平的降低导致旁分泌范例中Wnt信号传导的降低，但突变似乎不影响共表达Wnt在自分泌范式中的活性。连同观察到成骨细胞产生自分泌的正常Wnt，Wnt7b，并且该骨细胞产生旁分泌的Dkk1，我们认为G171V突变可能通过减少旁分泌Dkk1靶向拮抗的目标数量引起成骨细胞中Wnt活性的增加，而不会影响自分泌Wnt的活性。
