    • The present invention relates to methods based on the interactions of thrombin as a biological regulator. More specifically, the invention relates to the interactions of thrombin with regard to Notch signaling, Jaggedl, PAR1, and cellular effects mediated thereby. The invention relates to the discovery that thrombin cleaves Jagged l to produce non-membrane soluble Jagged l (sJl). The soluble Jagged l protein can affect Notch signaling and, among other things, mediate the release of FGF-1 and/or IL-lα from a cell. The invention further relates to the role(s) of thrombin and signaling via Notch proteins and the effect on thrombosis, angiogenesis, and/or differentiation, among other processes. Moreover, the invention relates to discovery that thrombin, sJl, and TRAP mediate, inter alia , rapid non-classical release of FGF-1, and proteins associated therewith ( e.g. , p40 Synl and S100A13, among others), and the effect growth and proliferation of a stem cell without loss of differentiation potential. Thus, the present invention relates to methods of clonally expanding a pluripotent stem cell while preserving the differentiation potential of the cell, a process termed "stamatogenesis."
    • 本发明涉及基于凝血酶作为生物调节剂的相互作用的方法。 更具体地,本发明涉及凝血酶与Notch信号传导,Jagged1,PAR1以及由此介导的细胞效应的相互作用。 本发明涉及凝血酶切割锯齿状I以产生非膜可溶性Jagged l(sJ1)的发现。 可溶性Jagged I蛋白可以影响Notch信号传导,并且其中包括从细胞介导FGF-1和/或IL-1α的释放。 本发明还涉及凝血酶的作用和通过Notch蛋白的信号通路以及其他过程中对血栓形成,血管生成和/或分化的作用。 此外,本发明涉及发现凝血酶,sJ1和TRAP尤其介导FGF-1的快速非经典释放和与其相关的蛋白质(例如,p40 Synl和S100A13等),以及效应生长和 干细胞的增殖而不损失分化潜能。 因此,本发明涉及克隆扩增多能干细胞同时保持细胞的分化潜能的方法,称为“致死生成”的过程。

    • The invention relates to a novel CTHRC1 nucleic acid and protein encoded thereby. Expression of CTHRC1 is induced by injury in, among others, arteries and skin, and CTHRC1 is expressed in bone, cartilage, kidney, lung and brain. CTHRC1 expression is associated with collagen matrix production, arterial remodeling, arterial restenosis, constrictive remodeling, vessel injury, ectopic ossification, fibrosis, and the like. CTHRC1 also plays a role in cell-cell and cell-matrix adhesion, cell-migration, and bone, cartilage, skin and brain development. CTHRC1 also regulates the level of BMPs, including BMP1 and BMP4, and the invention encompasses methods relating to affecting the level of BMPs by affecting the level of CTHRC1. In addition, the invention relates to modulation of the level of CTHRC1 to affect processes associated with fibrosis mediated by formation of collagen matrix. The invention further relates to methods of treating, preventing, and/or detecting these diseases, disorders or conditions, where the methods comprise modulating or detecting CTHRC1 expression and/or production of CTHRC1 polypeptide. The invention also relates to affecting CTHRC1 expression using cytokines.
    • 本发明涉及由此编码的新型CTHRC1核酸和蛋白质。 CTHRC1的表达是由动脉和皮肤等损伤引起的,CTHRC1在骨,软骨,肾,肺和脑中表达。 CTHRC1表达与胶原基质产生,动脉重塑,动脉再狭窄,缩窄重塑,血管损伤,异位骨化,纤维化等有关。 CTHRC1也在细胞和细胞 - 基质粘附,细胞迁移和骨,软骨,皮肤和脑发育中发挥作用。 CTHRC1还规定BMPs,包括BMP1和BMP4的水平,本发明包括通过影响CTHRC1水平影响BMP水平的方法。 此外,本发明涉及调节CTHRC1的水平以影响与形成胶原基质介导的纤维化相关的过程。 本发明还涉及治疗,预防和/或检测这些疾病,病症或病症的方法,其中所述方法包括调节或检测CTHRC1表达和/或产生CTHRC1多肽。 本发明还涉及使用细胞因子影响CTHRC1表达。
