    Description: Pharmacokinetic interactions between natural products (NPs) and conventional medications (prescription and nonprescription) are a longstanding but understudied problem in contemporary pharmacotherapy. Consequently, there are no established methods for selecting and prioritizing commercially available NPs to evaluate as precipitants of NP–drug interactions (NPDIs). As such, NPDI discovery remains largely a retrospective, bedside-to-bench process. This Recommended Approach, developed by the Center of Excellence for Natural Product Drug Interaction Research (NaPDI Center), describes a systematic method for selecting NPs to evaluate as precipitants of potential clinically significant pharmacokinetic NPDIs. Guided information-gathering tools were used to score, rank, and triage NPs from an initial list of 47 candidates. Triaging was based on the presence and/or absence of an NPDI identified in a clinical study (≥20% or 〈20% change in the object drug area under the concentration vs. time curve, respectively), as well as mechanistic and descriptive in vitro and clinical data. A qualitative decision-making tool, termed the fulcrum model, was developed and applied to 11 high-priority NPs for rigorous study of NPDI risk. Application of this approach produced a final list of five high-priority NPs, four of which are currently under investigation by the NaPDI Center.

    Description: Overcoming envelope metastability is crucial to trimer-based HIV-1 vaccine design. Here, we present a coherent vaccine strategy by minimizing metastability. For 10 strains across five clades, we demonstrate that the gp41 ectodomain (gp41 ECTO ) is the main source of envelope metastability by replacing wild-type gp41 ECTO with BG505 gp41 ECTO of the uncleaved prefusion-optimized (UFO) design. These gp41 ECTO -swapped trimers can be produced in CHO cells with high yield and high purity. The crystal structure of a gp41 ECTO -swapped trimer elucidates how a neutralization-resistant tier 3 virus evades antibody recognition of the V2 apex. UFO trimers of transmitted/founder viruses and UFO trimers containing a consensus-based ancestral gp41 ECTO suggest an evolutionary root of metastability. The gp41 ECTO -stabilized trimers can be readily displayed on 24- and 60-meric nanoparticles, with incorporation of additional T cell help illustrated for a hyperstable 60-mer, I3-01. In mice and rabbits, these gp140 nanoparticles induced tier 2 neutralizing antibody responses more effectively than soluble trimers.

    Description: Establishing the structure of molecules and solids has always had an essential role in physics, chemistry and biology. The methods of choice are X-ray and electron diffraction, which are routinely used to determine atomic positions with sub-angstrom spatial resolution. Although both methods are currently limited to probing dynamics on timescales longer than a picosecond, the recent development of femtosecond sources of X-ray pulses and electron beams suggests that they might soon be capable of taking ultrafast snapshots of biological molecules and condensed-phase systems undergoing structural changes. The past decade has also witnessed the emergence of an alternative imaging approach based on laser-ionized bursts of coherent electron wave packets that self-interrogate the parent molecular structure. Here we show that this phenomenon can indeed be exploited for laser-induced electron diffraction (LIED), to image molecular structures with sub-angstrom precision and exposure times of a few femtoseconds. We apply the method to oxygen and nitrogen molecules, which on strong-field ionization at three mid-infrared wavelengths (1.7, 2.0 and 2.3 mum) emit photoelectrons with a momentum distribution from which we extract diffraction patterns. The long wavelength is essential for achieving atomic-scale spatial resolution, and the wavelength variation is equivalent to taking snapshots at different times. We show that the method has the sensitivity to measure a 0.1 A displacement in the oxygen bond length occurring in a time interval of approximately 5 fs, which establishes LIED as a promising approach for the imaging of gas-phase molecules with unprecedented spatio-temporal resolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blaga, Cosmin I -- Xu, Junliang -- DiChiara, Anthony D -- Sistrunk, Emily -- Zhang, Kaikai -- Agostini, Pierre -- Miller, Terry A -- DiMauro, Louis F -- Lin, C D -- England -- Nature. 2012 Mar 7;483(7388):194-7. doi: 10.1038/nature10820.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, The Ohio State University, Columbus, Ohio 43210, USA. cblaga@mps.ohio-state.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22398558" target="_blank"〉PubMed〈/a〉

    Description: Oesophageal cancer is one of the most aggressive cancers and is the sixth leading cause of cancer death worldwide. Approximately 70% of global oesophageal cancer cases occur in China, with oesophageal squamous cell carcinoma (ESCC) being the histopathological form in the vast majority of cases (〉90%). Currently, there are limited clinical approaches for the early diagnosis and treatment of ESCC, resulting in a 10% five-year survival rate for patients. However, the full repertoire of genomic events leading to the pathogenesis of ESCC remains unclear. Here we describe a comprehensive genomic analysis of 158 ESCC cases, as part of the International Cancer Genome Consortium research project. We conducted whole-genome sequencing in 17 ESCC cases and whole-exome sequencing in 71 cases, of which 53 cases, plus an additional 70 ESCC cases not used in the whole-genome and whole-exome sequencing, were subjected to array comparative genomic hybridization analysis. We identified eight significantly mutated genes, of which six are well known tumour-associated genes (TP53, RB1, CDKN2A, PIK3CA, NOTCH1, NFE2L2), and two have not previously been described in ESCC (ADAM29 and FAM135B). Notably, FAM135B is identified as a novel cancer-implicated gene as assayed for its ability to promote malignancy of ESCC cells. Additionally, MIR548K, a microRNA encoded in the amplified 11q13.3-13.4 region, is characterized as a novel oncogene, and functional assays demonstrate that MIR548K enhances malignant phenotypes of ESCC cells. Moreover, we have found that several important histone regulator genes (MLL2 (also called KMT2D), ASH1L, MLL3 (KMT2C), SETD1B, CREBBP and EP300) are frequently altered in ESCC. Pathway assessment reveals that somatic aberrations are mainly involved in the Wnt, cell cycle and Notch pathways. Genomic analyses suggest that ESCC and head and neck squamous cell carcinoma share some common pathogenic mechanisms, and ESCC development is associated with alcohol drinking. This study has explored novel biological markers and tumorigenic pathways that would greatly improve therapeutic strategies for ESCC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Yongmei -- Li, Lin -- Ou, Yunwei -- Gao, Zhibo -- Li, Enmin -- Li, Xiangchun -- Zhang, Weimin -- Wang, Jiaqian -- Xu, Liyan -- Zhou, Yong -- Ma, Xiaojuan -- Liu, Lingyan -- Zhao, Zitong -- Huang, Xuanlin -- Fan, Jing -- Dong, Lijia -- Chen, Gang -- Ma, Liying -- Yang, Jie -- Chen, Longyun -- He, Minghui -- Li, Miao -- Zhuang, Xuehan -- Huang, Kai -- Qiu, Kunlong -- Yin, Guangliang -- Guo, Guangwu -- Feng, Qiang -- Chen, Peishan -- Wu, Zhiyong -- Wu, Jianyi -- Ma, Ling -- Zhao, Jinyang -- Luo, Longhai -- Fu, Ming -- Xu, Bainan -- Chen, Bo -- Li, Yingrui -- Tong, Tong -- Wang, Mingrong -- Liu, Zhihua -- Lin, Dongxin -- Zhang, Xiuqing -- Yang, Huanming -- Wang, Jun -- Zhan, Qimin -- England -- Nature. 2014 May 1;509(7498):91-5. doi: 10.1038/nature13176.

    Description: The human lens is comprised largely of crystallin proteins assembled into a highly ordered, interactive macro-structure essential for lens transparency and refractive index. Any disruption of intra- or inter-protein interactions will alter this delicate structure, exposing hydrophobic surfaces, with consequent protein aggregation and cataract formation. Cataracts are the most common cause of blindness worldwide, affecting tens of millions of people, and currently the only treatment is surgical removal of cataractous lenses. The precise mechanisms by which lens proteins both prevent aggregation and maintain lens transparency are largely unknown. Lanosterol is an amphipathic molecule enriched in the lens. It is synthesized by lanosterol synthase (LSS) in a key cyclization reaction of a cholesterol synthesis pathway. Here we identify two distinct homozygous LSS missense mutations (W581R and G588S) in two families with extensive congenital cataracts. Both of these mutations affect highly conserved amino acid residues and impair key catalytic functions of LSS. Engineered expression of wild-type, but not mutant, LSS prevents intracellular protein aggregation of various cataract-causing mutant crystallins. Treatment by lanosterol, but not cholesterol, significantly decreased preformed protein aggregates both in vitro and in cell-transfection experiments. We further show that lanosterol treatment could reduce cataract severity and increase transparency in dissected rabbit cataractous lenses in vitro and cataract severity in vivo in dogs. Our study identifies lanosterol as a key molecule in the prevention of lens protein aggregation and points to a novel strategy for cataract prevention and treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Ling -- Chen, Xiang-Jun -- Zhu, Jie -- Xi, Yi-Bo -- Yang, Xu -- Hu, Li-Dan -- Ouyang, Hong -- Patel, Sherrina H -- Jin, Xin -- Lin, Danni -- Wu, Frances -- Flagg, Ken -- Cai, Huimin -- Li, Gen -- Cao, Guiqun -- Lin, Ying -- Chen, Daniel -- Wen, Cindy -- Chung, Christopher -- Wang, Yandong -- Qiu, Austin -- Yeh, Emily -- Wang, Wenqiu -- Hu, Xun -- Grob, Seanna -- Abagyan, Ruben -- Su, Zhiguang -- Tjondro, Harry Christianto -- Zhao, Xi-Juan -- Luo, Hongrong -- Hou, Rui -- Perry, J Jefferson P -- Gao, Weiwei -- Kozak, Igor -- Granet, David -- Li, Yingrui -- Sun, Xiaodong -- Wang, Jun -- Zhang, Liangfang -- Liu, Yizhi -- Yan, Yong-Bin -- Zhang, Kang -- England -- Nature. 2015 Jul 30;523(7562):607-11. doi: 10.1038/nature14650.

    Description: Daoqin Zhang, Dan Xie, Xiwen Lin, Longfei Ma, Jian Chen, Daoqi Zhang, Yang Wang, Shuguang Duo, Yanmin Feng, Chunwei Zheng, Binjie Jiang, Yan Ning, and Chunsheng Han The postmeiotic development of male germ cells, also known as spermiogenesis, features the coordinated expression of a large number of spermatid-specific genes. However, only a limited number of key transcription factors have been identified and the underlying regulatory mechanisms remain largely unknown. Here, we report that SOX30, the most-divergent member of the Sry-related high-motility group box (SOX) family of transcription factors, is essential for mouse spermiogenesis. The SOX30 protein was predominantly expressed in spermatids, while its transcription was regulated by retinoic acid and by MYBL1 before and during meiosis. Sox30 knockout mice arrested spermiogenesis at step 3 round spermatids, which underwent apoptosis and abnormal chromocenter formation. We also determined that SOX30 regulated the expression of hundreds of spermatid-specific protein-coding and long non-coding RNA genes. SOX30 bound to the proximal promoter of its own gene and activated its transcription. These results reveal SOX30 as a novel key regulator of spermiogenesis that regulates its own transcription to enforce and activate this meiotic regulatory pathway.

    Description: Human cancers, including breast cancers, comprise clones differing in mutation content. Clones evolve dynamically in space and time following principles of Darwinian evolution, underpinning important emergent features such as drug resistance and metastasis. Human breast cancer xenoengraftment is used as a means of capturing and studying tumour biology, and breast tumour xenografts are generally assumed to be reasonable models of the originating tumours. However, the consequences and reproducibility of engraftment and propagation on the genomic clonal architecture of tumours have not been systematically examined at single-cell resolution. Here we show, using deep-genome and single-cell sequencing methods, the clonal dynamics of initial engraftment and subsequent serial propagation of primary and metastatic human breast cancers in immunodeficient mice. In all 15 cases examined, clonal selection on engraftment was observed in both primary and metastatic breast tumours, varying in degree from extreme selective engraftment of minor (〈5% of starting population) clones to moderate, polyclonal engraftment. Furthermore, ongoing clonal dynamics during serial passaging is a feature of tumours experiencing modest initial selection. Through single-cell sequencing, we show that major mutation clusters estimated from tumour population sequencing relate predictably to the most abundant clonal genotypes, even in clonally complex and rapidly evolving cases. Finally, we show that similar clonal expansion patterns can emerge in independent grafts of the same starting tumour population, indicating that genomic aberrations can be reproducible determinants of evolutionary trajectories. Our results show that measurement of genomically defined clonal population dynamics will be highly informative for functional studies using patient-derived breast cancer xenoengraftment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eirew, Peter -- Steif, Adi -- Khattra, Jaswinder -- Ha, Gavin -- Yap, Damian -- Farahani, Hossein -- Gelmon, Karen -- Chia, Stephen -- Mar, Colin -- Wan, Adrian -- Laks, Emma -- Biele, Justina -- Shumansky, Karey -- Rosner, Jamie -- McPherson, Andrew -- Nielsen, Cydney -- Roth, Andrew J L -- Lefebvre, Calvin -- Bashashati, Ali -- de Souza, Camila -- Siu, Celia -- Aniba, Radhouane -- Brimhall, Jazmine -- Oloumi, Arusha -- Osako, Tomo -- Bruna, Alejandra -- Sandoval, Jose L -- Algara, Teresa -- Greenwood, Wendy -- Leung, Kaston -- Cheng, Hongwei -- Xue, Hui -- Wang, Yuzhuo -- Lin, Dong -- Mungall, Andrew J -- Moore, Richard -- Zhao, Yongjun -- Lorette, Julie -- Nguyen, Long -- Huntsman, David -- Eaves, Connie J -- Hansen, Carl -- Marra, Marco A -- Caldas, Carlos -- Shah, Sohrab P -- Aparicio, Samuel -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2015 Feb 19;518(7539):422-6. doi: 10.1038/nature13952.

    Description: The repair and regeneration of tissues using endogenous stem cells represents an ultimate goal in regenerative medicine. To our knowledge, human lens regeneration has not yet been demonstrated. Currently, the only treatment for cataracts, the leading cause of blindness worldwide, is to extract the cataractous lens and implant an artificial intraocular lens. However, this procedure poses notable risks of complications. Here we isolate lens epithelial stem/progenitor cells (LECs) in mammals and show that Pax6 and Bmi1 are required for LEC renewal. We design a surgical method of cataract removal that preserves endogenous LECs and achieves functional lens regeneration in rabbits and macaques, as well as in human infants with cataracts. Our method differs conceptually from current practice, as it preserves endogenous LECs and their natural environment maximally, and regenerates lenses with visual function. Our approach demonstrates a novel treatment strategy for cataracts and provides a new paradigm for tissue regeneration using endogenous stem cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Haotian -- Ouyang, Hong -- Zhu, Jie -- Huang, Shan -- Liu, Zhenzhen -- Chen, Shuyi -- Cao, Guiqun -- Li, Gen -- Signer, Robert A J -- Xu, Yanxin -- Chung, Christopher -- Zhang, Ying -- Lin, Danni -- Patel, Sherrina -- Wu, Frances -- Cai, Huimin -- Hou, Jiayi -- Wen, Cindy -- Jafari, Maryam -- Liu, Xialin -- Luo, Lixia -- Zhu, Jin -- Qiu, Austin -- Hou, Rui -- Chen, Baoxin -- Chen, Jiangna -- Granet, David -- Heichel, Christopher -- Shang, Fu -- Li, Xuri -- Krawczyk, Michal -- Skowronska-Krawczyk, Dorota -- Wang, Yujuan -- Shi, William -- Chen, Daniel -- Zhong, Zheng -- Zhong, Sheng -- Zhang, Liangfang -- Chen, Shaochen -- Morrison, Sean J -- Maas, Richard L -- Zhang, Kang -- Liu, Yizhi -- R37 AG024945/AG/NIA NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2016 Mar 17;531(7594):323-8. doi: 10.1038/nature17181.
