UNIVERSITY OF CALIFORNIA Los Angeles Dissecting transcriptional control by Klf4 in somatic cell reprogramming A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Biological Chemistry by Huajun Zhou 2017 ABSTRACT OF THE DISSERTATION Dissecting transcriptional control by Klf4 in somatic cell reprogramming by Huajun Zhou Doctor of Philosophy in Biological Chemistry University of California, Los Angeles, 2017 Professor Gregory S. Payne, Chair Ectopic expression of four transcription factors, Oct4, Sox2, Klf4, and c-Myc, coverts somatic cells directly into induced pluripotent stem cells (iPSCs), which are functionally equivalent to embryonic stem cells (ESCs). The discovery of iPSC has been reshaping the methodology of disease modeling and drug screening in the past decade, and provides tremendous promise for regenerative medicine. However, the mechanism underlying this conversion process, reprogramming, is not yet fully understood. I aimed to dissect the reprogramming process, by characterizing the functional domains of one reprogramming factor Klf4. The transcriptional activation domain (TAD) of Klf4 was revealed to be critical for reprogramming. To search for the factors that mediates the functionality of Klf4 TAD, I identified transcriptional coactivators CBP/p300 and Mediator complex as the physical interaction partners of Klf4 TAD, and further showed that this interaction is functionally required ii for Klf4 mediated transcriptional activation in reprograming. Clathrin heavy chain, initially identified as a physical interaction partner of Klf4 TAD, was shown to be not required for Klf4 transcriptional activation. Clathrin heavy chain was furthered characterized for its potential transcriptional activation activity in CHC-TFE3, a chromosomal fusion discovered in renal cell carcinoma. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -
Meta-Analyses of Expression Profiling Data in the Postmortem
META-ANALYSES OF EXPRESSION PROFILING DATA IN THE POSTMORTEM HUMAN BRAIN by Meeta Mistry B.Sc., McMaster University, 2005 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE STUDIES (Bioinformatics) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) July 2012 © Meeta Mistry, 2012 Abstract Schizophrenia is a severe psychiatric illness for which the precise etiology remains unknown. Studies using postmortem human brain have become increasingly important in schizophrenia research, providing an opportunity to directly investigate the diseased brain tissue. Gene expression profiling technologies have been used by a number of groups to explore the postmortem human brain and seek genes which show changes in expression correlated with schizophrenia. While this has been a valuable means of generating hypotheses, there is a general lack of consensus in the findings across studies. Expression profiling of postmortem human brain tissue is difficult due to the effect of various factors that can confound the data. The first aim of this thesis was to use control postmortem human cortex for identification of expression changes associated with several factors, specifically: age, sex, brain pH and postmortem interval. I conducted a meta-analysis across the control arm of eleven microarray datasets (representing over 400 subjects), and identified a signature of genes associated with each factor. These genes provide critical information towards the identification of problematic genes when investigating postmortem human brain in schizophrenia and other neuropsychiatric illnesses. The second aim of this thesis was to evaluate gene expression patterns in the prefrontal cortex associated with schizophrenia by exploring two methods of analysis: differential expression and coexpression. -

Differential Requirements for Tousled-Like Kinases 1 and 2 in Mammalian Development

All rights reserved 1350-9047/17 www.nature.com/cdd Differential requirements for Tousled-like kinases 1 and 2 in mammalian development Sandra Segura-Bayona1,8, Philip A Knobel1,8, Helena González-Burón1,8, Sameh A Youssef2,3, Aida Peña-Blanco1, Étienne Coyaud4,5, Teresa López-Rovira1, Katrin Rein1, Lluís Palenzuela1, Julien Colombelli1, Stephen Forrow1, Brian Raught4,5, Anja Groth6, Alain de Bruin2,7 and Travis H Stracker*,1 The regulation of chromatin structure is critical for a wide range of essential cellular processes. The Tousled-like kinases, TLK1 and TLK2, regulate ASF1, a histone H3/H4 chaperone, and likely other substrates, and their activity has been implicated in transcription, DNA replication, DNA repair, RNA interference, cell cycle progression, viral latency, chromosome segregation and mitosis. However, little is known about the functions of TLK activity in vivo or the relative functions of the highly similar TLK1 and TLK2 in any cell type. To begin to address this, we have generated Tlk1- and Tlk2-deficient mice. We found that while TLK1 was dispensable for murine viability, TLK2 loss led to late embryonic lethality because of placental failure. TLK2 was required for normal trophoblast differentiation and the phosphorylation of ASF1 was reduced in placentas lacking TLK2. Conditional bypass of the placental phenotype allowed the generation of apparently healthy Tlk2-deficient mice, while only the depletion of both TLK1 and TLK2 led to extensive genomic instability, indicating that both activities contribute to genome maintenance. Our data identifies a specific role for TLK2 in placental function during mammalian development and suggests that TLK1 and TLK2 have largely redundant roles in genome maintenance. -
