  • TFEB regulates lysosomal proteostasis 

    Song, Wensi; Wang, Fan; Savini, Marzia; Ake, Ashley; di Ronza, Alberto; Sardiello, Marco; Segatori, Laura (2013)
    Loss-of-function diseases are often caused by destabilizing mutations that lead to protein misfolding and degradation. Modulating the innate protein homeostasis (proteostasis) capacity may lead to rescue of native folding ...
  • Three-dimensional in vitro tumor models for cancer research and drug evaluation 

    Xu, Xian; Farach-Carson, Mary C.; Jia, Xinqiao (2014)
    Cancer occurs when cells acquire genomic instability and inflammation, produce abnormal levels of epigenetic factors/proteins and tumor suppressors, reprogram the energy metabolism and evade immune destruction, leading to ...
  • Three-dimensional photolithographic micropatterning: a novel tool to probe the complexities of cell migration 

    Hoffmann, Joseph C.; West, Jennifer L. (2013)
    In order to independently study the numerous variables that influence cell movement, it will be necessary to employ novel tools and materials that allow for exquisite control of the cellular microenvironment. In this ...
  • The three-way switch operation of Rac1/RhoA GTPase-based circuit controlling amoeboid-hybrid-mesenchymal transition 

    Huang, Bin; Lu, Mingyang; Jolly, Mohit Kumar; Tsarfaty, Ilan; Onuchic, José; Ben-Jacob, Eshel (2014-09-23)
    Metastatic carcinoma cells exhibit at least two different phenotypes of motility and invasion - amoeboid and mesenchymal. This plasticity poses a major clinical challenge for treating metastasis, while its underlying ...
  • Tunable optical tweezers for wavelength-dependent measurements 

    Hester, Brooke; Campbell, Gretchen K.; Lopez-Mariscal, Carlos; Filgueira, Carly Levin; Huschka, Ryan; Halas, Naomi J.; Helmerson, Kristian (2012)
    Optical trapping forces depend on the difference between the trap wavelength and the extinction resonances of trapped particles. This leads to a wavelength-dependent trapping force, which should allow for the optimization ...
  • Ultrasensitivity of the Bacillus subtilis sporulation decision 

    Narula, Jatin; Devi, Seram N.; Fujita, Masaya; Igoshin, Oleg A. (2012-11-19)
    Starving Bacillus subtilis cells execute a gene expression program resulting in the formation of stress-resistant spores. Sporulation master regulator, Spo0A, is activated by a phosphorelay and controls the expression ...
  • Unraveling the regulatory connections between two controllers of breast cancer cell fate 

    Lee, Jinho; Tiwari, Abhinav; Shum, Victor; Mills, Gordon B.; Mancini, Michael A.; Igoshin, Oleg A.; Balázsi, Gábor (2014)
    Estrogen receptor alpha (ERα) expression is critical for breast cancer classification, high ERα expression being associated with better prognosis. ERα levels strongly correlate with that of GATA binding protein 3 (GATA3), ...
  • Use of Myocardial Matrix in a Chitosan-Based Full-Thickness Heart Patch 

    Pok, Seokwon; Benavides, Omar M.; Hallal, Patrick; Jacot, Jeffrey G. (2014)
    A novel cardiac scaffold comprised of decellularized porcine heart matrix was investigated for use as a biodegradable patch with a potential for surgical reconstruction of the right ventricular outflow tract. Powdered heart ...
  • Variations in optical coherence tomography resolution and uniformity: a multi-system performance comparison 

    Fouad, Anthony; Pfefer, T. Joshua; Chen, Chao-Wei; Gong, Wei; Agrawal, Anant; Tomlins, Peter H.; Woolliams, Peter D.; Drezek, Rebekah A.; Chen, Yu (2014)
    Point spread function (PSF) phantoms based on unstructured distributions of sub-resolution particles in a transparent matrix have been demonstrated as a useful tool for evaluating resolution and its spatial variation across ...
  • Why Zeolites Have So Few 7-Membered Rings 

    Li, Xi; Deem, Michael W. (2014)
    Known zeolite structures have relatively few 7-membered rings. Previous quantum mechanical calculations suggest there is no particular energy penalty for 7-membered rings. Predicted zeolite structures sampled from all ...
