A Mutant p53-Dependent Embryonic Stem Cell Gene Signature Is Associated with Augmented Tumorigenesis of Stem Cells
cancer res. http://cancerres.aacrjournals.org/content/78/20/5833 33:00
抑癌基因P53突变-人癌症种最常见突变types【P53-inavtivating mutation & P53 oncogenic GOF突变促癌】
cancer therapy challenge 【针对CSC (cancer stem cell)】
P53 mutated MSC-->Tumor lines-->CSC features (oncogenicity&CSC markers)-->对比来源MSC与tumor-->indentify molecular events (比如与ESC gene signature related)-->而KO mutant P53, 肿瘤发育变低,成瘤率变低,CSC maker变低,ESC-MSC-TLs signature变低-->题目【依赖P53的ESC gene signature与CSC关系】
Personal conclusion【对CSC研究,找到marker,潜在的CR治疗靶点。利用成瘤前后细胞对比找突破口,最终与P53&ESC联系起来的signature作为可能的治疗靶点。】
Growth-restricting effects of siRNA transfections: a largely deterministic combination of off-target binding and hybridization-independent competition
NAR https://academic.oup.com/nar/article/46/18/9309/5095462 7:00
siRNAs(small interfeing RNAs)脱靶和KD效率是其存在的两大问题,本文进一步发现了它对细胞生长和活性的不利影响,广泛存在于人鼠多种细胞系中,并推测其原因是其导致的细胞内miRNA机器的过饱和,破坏了内源miRNA的功能。
Personal 【这是找缺点,但真有这么大影响么,现在还是有很多siRNAs文库被用来做筛选,平台就有很多库,可以避免的么?】

Retool AI to forecast and limit wars
nature https://www.nature.com/articles/d41586-018-07026-4 10:00
Since 2011, conflicts worldwide have killed up to 100,000 people a year, three-quarters of whom were in Afghanistan, Iraq and Syria. Several examples are under way. These include Lockheed Martin’s Integrated Crisis Early Warning System, the Alan Turing Institute’s project on global urban analytics for resilient defence (run by W.G. and A.W.) and the US government’s Political Instability Task Force.
代码通过新闻报道数据库预测紧张关系以及军事。目前已有系统在做这个事,如上。将来的AI还需要能对暴力来源做解释并制定阻止的策略。动态多变的冲突需要更多的相关可能引起冲突的信息,以及新的机器学习计数,更准确的反应社会反响与人做决策的理论模型。
