RNA干扰pygo2基因对人脑胶质母细胞瘤U251生物学行为及wnt通路的影响
Zhongguo shiyan zhenduanxue, 2015 目的研究pygo2在胶质瘤细胞系U251中的表达、功能及作用机制。方法利用反义pygo2转染U251,下调pygo2的表达,应用流式细胞术和MTT法,评价细胞生长、增殖、凋亡及周期变化;细胞克隆形成试验和transwell侵袭试验分析细胞的克隆形成能力和侵袭能力,采用Western印迹法检测通路蛋白的表达变化。结果转染反义pygo2后,pygo2表达降低,MTT结果显示转染反义pygo2后细胞生长受到抑制且凋亡细胞增加;流式细胞术提示G1期到S期阻滞,细胞克隆形成能力下降,侵袭能力均受到抑制 ...

β-Catenin inhibition shapes tumor immunity and synergizes with immunotherapy in colorectal cancer
OncoImmunology, 2020 In colorectal cancer, Wnt/β-catenin signaling is often aberrantly activated and associated with a T-cell-excluded phenotype which is a major obstacle for many immunotherapies.

Dorsalization of the neural tube by the non-neural ectoderm [PDF]
, 1995 The patterning of cell types along the dorsoventral axis of the spinal cord requires a complex set of inductive signals. While the chordamesoderm is a well-known source of ventralizing signals, relatively little is known about the cues that induce dorsal

Advanced Healthcare Materials, EarlyView.Cerebral organoids are transforming brain research, yet the field remains fragmented. This comprehensive systematic review maps 738 studies published between 2014 and 2024 to uncover trends, gaps, and opportunities across neuroscience. Introducing OrganoidMap—an interactive, open‐access platform to explore and compare models—this work enables ...

Frizzled Proteins are bona fide G Protein-Coupled Receptors [PDF]
, 2009 Receptors of the Frizzled family initiate Wnt ligand-dependent signaling controlling multiple steps in organism development and highly conserved in evolution. Misactivation of the Wnt/Frizzled signaling is cancerogenic.

Advanced Healthcare Materials, EarlyView.This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...
