On Comparing The Clustering Of Regression Models Method With K-Means Clustering, Li-Xuan Qin, Steven G. Self

Memorial Sloan-Kettering Cancer Center, Dept. of Epidemiology & Biostatistics Working Paper Series

Gene clustering is a common question addressed with microarray data. Previous methods, such as K-means clustering and hierarchical clustering, base gene clustering directly on the observed measurements. A new model-based clustering method, the clustering of regression models (CORM) method, bases the clustering of genes on their relationship to covariates. It explicitly models different sources of variations and bases gene clustering solely on the systematic variation. Both being partitional clustering, CORM is closely related to K-means clustering. In this paper, we discuss the relationship between the two clustering methods in terms of both model formulation and implications on other important aspects …

Resonances And Threshold Effects In Low-Energy Electron Collisions With Methyl Halides, Gordon A. Gallup, Ilya I. Fabrikant

Gordon Gallup Publications

Cross sections for elastic and inelastic electron collisions with CH₃X(X =Cl,Br, I) molecules are calculated. For the lowest partial wave, the resonance R-matrix theory, and for the higher partial waves, the theory of scattering by dipolar plus polarization potential, are used. It is shown that the rotationally elastic scattering amplitude for a polar molecule in the fixed-nuclei approximation is logarithmically divergent for the forward direction, and a closure formula is derived to speed up the convergence at small angles. In treating the nuclear motion, only C-X stretch vibrations are taken into account. The dipole moment …

Shp-2 Tyrosine Phosphatase Inhibits P73-Dependent Apoptosis And Expression Of A Subset Of P53-Target Genes Induced By The Green Tea Polyphenol Egcg, Arm R. Amin, Vijay S. Thakur, Rajib K. Paul, Gen Sheng Feng, Cheng-Kui Qu, Hasan Muktar, Munna L. Agarwal

Pharmaceutical Science and Research

Green tea polyphenol, epigallocatechin-3-gallate (EGCG) differentially regulates the cellular growth of cancer cells in a p53-dependent manner through apoptosis and/or cell cycle arrest. In an effort to further elucidate the mechanism of differential growth regulation by EGCG, we have investigated the role of the tyrosine phosphatase, SHP-2. Comparing the responses of mouse embryonic fibroblasts (MEFs), expressing either WT or functionally inactive/truncated SHP-2, we find that inactivation of SHP-2 remarkably sensitizes cells to EGCG-mediated killing. MEFs lacking functional SHP-2 undergo massive apoptosis upon treatment with EGCG. By comparing gene expression profiles, we have identified a set of transcriptional targets of p53 …

The Maturation Of Mucus-Secreting Gastric Epithelial Progenitors Into Digestive-Enzyme Secreting Zymogenic Cells Requires Mist1 , Victoria G. Ramsey, Jason M. Doherty, Christopher C. Chen, Thaddeus S. Stappenbeck, Stephen F. Konieczny, Jason C. Mills

Oncological Sciences Center Publications

Continuous regeneration of digestive enzyme (zymogen)-secreting chief cells is a normal aspect of stomach function that is disrupted in precancerous lesions ( e. g. metaplasias, chronic atrophy). The cellular and genetic pathways that underlie zymogenic cell (ZC) differentiation are poorly understood. Here, we describe a gene expression analysis of laser capture microdissection purified gastric cell populations that identified the bHLH transcription factor Mist1 as a potential ZC regulatory factor. Our molecular and ultrastructural analysis of proliferation, migration and differentiation of the gastric unit in Mist1(-/-) and control mice supports a model whereby wild-type ZC progenitors arise as neck cells in …

Acm1 Is A Negative Regulator Of The Cdh1-Dependent Anaphase-Promoting Complex/Cyclosome In Budding Yeast , Juan S. Martinez, Dah-Eun Jeong, Eunyoung Choi, Brian M. Billings, Mark C. Hall

Oncological Sciences Center Publications

Cdh1 is a coactivator of the anaphase-promoting complex/cyclosome (APC/C) and contributes to mitotic exit and G(1) maintenance by facilitating the polyubiquitination and subsequent proteolysis of specific substrates. Here, we report that budding yeast Cdh1 is a component of a cell cycle-regulated complex that includes the 14-3-3 homologs Bmh1 and Bmh2 and a previously uncharacterized protein, which we name Acm1 (Apc/c(Cdh1) modulator 1). Association of Cdh1 with Bmh1 and Bmh2 requires Acm1, and the Acm1 protein is cell cycle regulated, appearing late in G(1) and disappearing in late M. In acm1 Delta strains, Cdh1 localization to the bud neck and association …

Minimum Length Requirement Of The Flexible N-Terminal Translocation Subdomain Of Colicin E3 , Onkar Sharma, William A. Cramer

Oncological Sciences Center Publications

The 315-residue N-terminal T domain of colicin E3 functions in translocation of the colicin across the outer membrane through its interaction with outer membrane proteins including the OmpF porin. The first 83 residues of the T domain are known from structure studies to be disordered. This flexible translocation subdomain contains the TolB box (residues 34 to 46) that must cross the outer membrane in an early translocation event, allowing the colicin to bind to the TolB protein in the periplasm. In the present study, it was found that cytotoxicity of the colicin requires a minimum length of 19 to 23 …

Microfluidic Cell Fusion Under Continuous Direct Current Voltage , Jun Wang, Chang Lu

Oncological Sciences Center Publications

The authors report a technique which produces cell-to-cell electrofusion using a common direct current power supply on a microfluidic platform. In the authors' method, the cells were first conjugated based on biotin-streptavidin interaction. The electrofusion was then conducted by flowing the linked cells through a simple microfluidic channel with geometric variation under continuous direct current voltage. This microfluidics-based technique offers processing at the level of single cell pairs with efficiency comparable to that of conventional electrofusion technique based on electrical pulses.

The Niemann-Pick Type C2 Protein Loads Isoglobotrihexosylceramide Onto Cd1d Molecules And Contributes To The Thymic Selection Of Nkt Cells, Paul B. Savage, Nicolas Schrantz, Yuval Sagiv, Yang Liu, Albert Bendelac, Luc Teyton

Faculty Publications

The Niemann-Pick type C2 (NPC2) protein is a small, soluble, lysosomal protein important for cholesterol and sphingolipid transport in the lysosome. The immunological phenotype of NPC2-deficient mice was limited to an impaired thymic selection of Valpha 14 natural killer T cells (NKT cells) and a subsequent reduction of NKT cells in the periphery. The remaining NKT cells failed to produce measurable quantities of interferon-gamma in vivo and in vitro after activation with alpha-galactosylceramide. In addition, thymocytes and splenocytes from NPC2-deficient mice were poor presenters of endogenous and exogenous lipids to CD1d-restricted Valpha 14 hybridoma cells. Importantly, we determined that similar …

Inhibition Of Caveolar Uptake, Sv40 Infection, And Β1-Integrin Signaling By A Nonnatural Glycosphingolipid Stereoisomer, Raman Deep Singh, Eileen L. Holicky, Zhi-Jie Cheng, Seong-Youl Kim, Christine L. Wheatley, David L. Marks, Robert Bittman, Richard E. Pagano

Publications and Research

Caveolar endocytosis is an important mechanism for the uptake of certain pathogens and toxins and also plays a role in the internalization of some plasma membrane (PM) lipids and proteins. However, the regulation of caveolar endocytosis is not well understood. We previously demonstrated that caveolar endocytosis and β1-integrin signaling are stimulated by exogenous glycosphingolipids (GSLs). In this study, we show that a synthetic GSL with nonnatural stereochemistry, β-d-lactosyl-N-octanoyl-l-threo-sphingosine, (1) selectively inhibits caveolar endocytosis and SV40 virus infection, (2) blocks the clustering of lipids and proteins into GSLs and cholesterol-enriched microdomains (rafts) at the PM, and (3) inhibits β1-integrin activation and …

Intrarectal Transmission, Systemic Infection, And Cd4+ T Cell Depletion In Humanized Mice Infected With Hiv-1, Zhifeng Sun, Paul W. Denton, Jacob D. Estes, Florence A. Othieno, Bangdong L. Wei, Anja K. Wege, Michael W. Melkus, Angela Padgett-Thomas, Mary Zupancic, Ashley T. Haase, J. Victor Garcia

Biology Faculty Publications

Intrarectal infection between men who have sex with men represents a predominant form of human immunodefi ciency virus (HIV) transmission in developed countries. Currently there are no adequate small animal models that recapitulate intrarectal HIV transmission. Here we demonstrate that human lymphocytes generated in situ from hematopoietic stem cells reconstitute the gastrointestinal tract of humanized mice with human CD4+ T cells rendering them susceptible to intrarectal HIV transmission. HIV infection after a single intrarectal inoculation results in systemic infection with depletion of CD4+ T cells in gut-associated lymphoid tissue and other pathologic sequela that closely mimics those observed in HIV …
