生命科学在智利的新发展
在美国度过25年后,巴伦苏埃拉重新回到智利，他创办生命科学相关的基金会，去表明科学对经济和社会发展的重要性，他相信，投资在科学研究将改善智利目前的经济，并有助于推动它在新的方向前进。
未折叠蛋白反应的发现
Proteins that are secreted from the cell or inserted into the plasma membrane, transit through the endoplasmic reticulum where they are properly folded and assembled and may undergo post-translational modification. Walter tells the story of the exciting discovery made in his lab of the "unfolded protein response", a feedback pathway that ensures that the cell makes enough ER to properly modify all the secreted proteins in the cell.
肌球蛋白和驱动蛋白的探索发现之旅
Vale explains how doing science often follows a winding path with unexpected, sometimes wonderful surprises, and uses his own story to illustrate his point. When Vale was a graduate student, he initially hoped to show that myosin was involved in axonal transport, but ended up discovering a new molecule which he called kinesin.
现代遗传学与农业的可持续性发展
Pamela Ronald (UC Davis) Part 1: Sustainable agriculture
In Part 1 of her lecture, Ronald emphasizes the importance of developing sustainable agricultural practices that will allow the world's population to be fed without destroying the Earth. Ronald demonstrates that modern genetics approaches have facilitated development of new crop varieties that can increase crop yields while reducing insecticide use. She proposes that the judicious incorporation of two important strands of agriculture—agricultural biotechnology and agroecological practices—is key to helping feed the growing population and she provides compelling examples to support her stand.
研究寄生虫的质体，提供药物开发的新靶点
David Roos (U Penn) Part 2: The apicomplexan plastid
Antibiotics are effective because they kill bacteria without harming humans and other eukaryotes (organisms with cells that contain nuclei). So why are the eukaryotic parasites responsible for malaria and toxoplasmosis killed by drugs like clindamycin? Multidisciplinary studies integrating molecular genetics, cell biology, biochemistry, pharmacology and computational genomics reveal that such drugs target an unusual organelle. The "apicoplast" was acquired when an ancestral organism 'ate' a eukaryotic alga, and retained the algal plastid -- a relative of plant chloroplasts derived from a bacterial ancestor. Although no longer photosynthetic, the apicoplast is essential for parasite survival, providing new targets for drug development. See more at http://www.ibioseminars.org
GE：抗体药物开发中细胞培养基的筛选、优化与补料策略
在抗体药物的开发过程中如何选择合适的无血清细胞培养基，在实验结果未达到预期要求时，如何做培养基的优化，及feed-batch培养模式下，如何优化补料策略，来提升细胞状态、延长表达周期、提高抗体产量。
深入地表以下，发现美景和科学
洞穴探险家、地理学家弗朗西斯科·绍罗深入位于我们脚底的隐藏大陆，调查地球深处那些从未被人踏足过的黑暗之地。在南美洲壮丽的特普伊山，他发现了新的矿物质和与世隔绝、独自进化的昆虫，他还运用自己关于这些“外星世界”的知识来训练宇航员。
胚胎发育的模式
Following fertilization, the single celled embryo undergoes a number of mitotic divisions to produce a ball of cells called a blastula or blastoderm. Although these cells are all genetically identical, they gradually begin to express different gene products that reflect the regions of the adult body they will form. In my first lecture I discuss how these initial patterns of gene expression arise. In Drosophila, a maternally supplied transcription factor called Bicoid plays a particularly important role. Bcd RNA is anchored at the anterior end of the egg but is only translated after fertilization. From that anterior source, Bcd protein is thought to diffuse through the egg, establishing a concentration gradient that activates different genes at different thresholds.

如何应对下一场流行病毒的爆发
当2014年3月埃博拉疫情爆发，Pardis Sabeti和她的团队就开始了，该病毒的基因组测序的工作，了解它是如何变异和传播的。并同时在网上公布她的研究成果。之后，更多的病毒研究者和来自世界各地的科学家都参与到这场紧急的战斗中。在这次课程中，她展示了开放合作，是阻止下一场流行病毒爆发的关键...
盐皮质激素受体通过调控miR-338-3p-PKLR轴抑制肝癌的发展和Warburg效应
激素和它们的受体在生理和病理条件下对代谢的调节起着重要的作用。我们在4株肝癌细胞用siRNA的方法筛选20种激素受体对肝癌细胞的瓦伯格效应（Warburg effect）尤其是乳酸产生的影响。我们发现很多受体的siRNA都影响乳酸的产生。其中盐皮质激素受体(mineralocorticoid receptor, MR) 的siRNA在4株肝癌细胞都表现出增加乳酸的产生。体外和体内实验表明MR影响细胞增殖、细胞周期和凋亡。进一步的机制研究揭示，作为一个转录因子，MR直接调节miR-338-3p的表达，而miR-338-3p又通过靶基因PKLR(pyruvate kinase, liver and red blood，糖酵解途径的关键酶)来抑制肝癌细胞的瓦伯格效应。另外，与癌旁组织相比，有81%的肝癌病人的肝癌组织中MR的表达都发生下调。这种下调是由MR的染色体缺失和去乙酰化引起的。在肿瘤组织中，MR的低表达和病人的预后差相关；miR-338-3p的表达和MR的表达水平呈正相关，和PKLR的表达呈负相关。结论：我们的研究首次揭示了MR通过miR-338-3p/PKLR这个途径抑制肝癌的瓦伯格效应。
