I bow my head, with all the humility and modesty, before Allah Almighty, the creator, the most supreme whose mercy enabled me to accomplish this task and bestowed me with success. May Allah shower His countless salutation upon His all Prophets including Muhammad (PBUH), His last messenger, who is the fountain of knowledge and guidance for the salvation of mankind in this world and in the hereafter. This gives me the privilege to acknowledge few of those people whose sincere help, guidance and prayers enabled me to accomplish my research work in a congenial and serene environment. First of all, I would like to pay attributes to all Directors (Drs. Yusuf Zafar, Zafar Mehmood Khalid, Sohail Hameed and Shahid Mansoor, SI) of the National Institute of Biotechnology and Genetic Engineering (NIBGE), Faisalabad, Pakistan for providing me congenial environment for pursuing for my PhD. I must express my sincere regards to my supervisor Dr.Mehboob-Ur-Rahman (Pride of Performance) for his continuous guidance and patience throughout my study. I am greatly obliged to my co-supervisor Dr.Yusuf Zafar for his helpful suggestions without which it would not have been possible to begin the present to a successful end. I am thankful to the Director cotton CCRI Multan for providing us the leaves of Gossypium species. I am also grateful to late Prof J. McD. Stewart (University of Arkansas, Fayetteville, Arkansas, USA) for providing us the genomic DNA of G. hirsutum ‘‘yucatanense’’, G. capitis-viridis, G. longicalyx and G. australe. I too acknowledge Prof Andrew H Paterson (PGML, UGA, USA) for providing me research facilities in his labs for carrying out a part of my PhD thesis research work. I am also grateful to my lab fellows Dr.Tayyaba Shaheen, Mr. M Atif Iqbal and Mr. Zaman as well as field staff members, Mr. Shehbaz Shabbir, Mr.Wasif Ali and Mr. Muhammad Farooq for their support and cooperation. Funds for this research work were largely utilised through a project entitled “DNA- based genetic characterization of cotton Germplasm (Component-1, NIBGE, Faisalabad) financed through ALP-PARC program. I am also thankful to HEC Islamabad Pakistan for providing funds for doing some lab experiments in PGML, University of Georgia USA. I owe a heartfelt debt of gratitude to my parents, who endured all the strains and stress during the course of my study and whose hearts were beating with prayers for my success. I am also indebted and grateful to my brothers and sisters who always remembered me in their prayers. I am especially thankful to my sister Sonia Tabbasam whose help in take caring of my kids made me able to complete this work. I gratefully acknowledge the encouragement and support from my husband Mr. Fakhar Z. Wahla (Director Admin, BARDC, PARC, Quetta), whose love, support, encouragement, patience and praying made this work possible. I am also thankful to my in Laws for their encouragement and good wishes during my studies. Last but not the least are my loving kids Ch. Shehram Fakhar and Haleema Zaman, their tiny hands were always raised in prayers for my success. I am thankful to Allah Almighty, without His help it was impossible to complete this research work.

    ANNOTATION OF THE HUMAN ODONTOBLAST CELL LAYER AND DENTAL PULP PROTEOMES AND N-TERMINOMES by Simon Abbey B.Sc., Queen’s University, 1989 D.M.D., The University of British Columbia, 1997 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate and Postdoctoral Studies (Craniofacial Science) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) July 2017 © Simon Abbey, 2017 Abstract The proteome and N-terminome of the human odontoblast cell layer was identified for the first time by shotgun proteomic and terminal amine isotopic labeling of substrates (TAILS) N-terminomic analyses, respectively, and compared with that of human dental pulp stroma from 3rd molar teeth. After reverse-phase liquid chromatography-tandem mass spectrometry, >170,000 spectra from the shotgun and TAILS analyses were matched by four search engines to 4,888 and 12,063 peptides in the odontoblast cell layer and pulp stroma, respectively. Using the Trans-Proteomic Pipeline, I identified 895 and 2,423 unique proteins in these tissues at an FDR of ≤ 1 %. In the odontoblast cell layer proteome I found proteomic evidence for dentin sialophosphoprotein, which is cleaved into dentin phosphoprotein and dentin sialoprotein, proteins that are important in dentin mineralization. Further, 222 proteins of the odontoblast cell layer were not found in the pulp, suggesting many of these proteins are synthesized preferentially by odontoblasts. I also found minor differences in the odontoblast cell layer between the dental pulp proteomes of older and younger donors. The human dental pulp stroma proteome was expanded by 974 new proteins, not previously identified among the 4,123 proteins identified in our previous dental pulp study (Eckhard et al., 2015).

  • Figure S-1: Gene Ontology Categories Classification (Panther) of All Identified Regulated Proteins According to Their Cellular Functions
    Figure S-1: Gene Ontology Categories Classification (Panther) of all identified regulated proteins according to their cellular functions. Proteins were assigned to 16 biological processes and 11 molecular function categories. Figure S-1 Figure S-2: Visualization of time-related effects by Voronoi Treemaps of CAP treated vs. untreated S9 epithelial cells. Identified proteins were assorted into individualised KEGG-BRITE hierarchy followed by the extraction of the sub-class “oxidative stress” (A). Oxidative stress related proteins were displayed for the time courses from 0 h up to 72 h (B). Every tile in that structural hierarchy, representing one identified protein, was coloured by fold-changes (logarithmic normalized expression values from Delta-2D of CAP treated samples divided by expression values of untreated controls). The colour gradient encodes expression changes: white coloured tiles show expressions, which correspond to a fold change of ‘1’. Blue shaded tiles represent proteins with negative fold-changes (lower expression in CAP treated samples in comparison to the untreated controls) and shades of orange represent proteins with fold-changes higher than ‘1’. Saturation of blue and orange is reached at an expression rate five times higher or lower than the corresponding control. The six different time points 0 h, 0.5 h, 1 h, 24 h, 48 h and 72 h are displayed.

Children are devoid of preexisting CVD and provide unique insight into specificuremia-andPD-inducedpathomechanismsofCVD.We obtained peritoneal specimens from children with stage 5 CKD at time of PD catheter insertion (CKD5 group), children with established PD (PD group), and age-matched nonuremic controls (n=6/group). We microdissected omental arterioles from tissue layers not directly exposed to PD fluid and used adjacent sections of four arterioles per patient for transcriptomic and proteomic analyses.

    Function and transport of a herpesvirus encoded Ubiquitin-specific protease in virus entry and assembly A thesis submitted to the degree of Doctor of Philosophy Imperial College London, Department of Medicine by Thomas Hennig Supervised by Professor Peter F. O’Hare Supported by Imperial College London and the Wellcome Trust September 2011 - June 2015 - 1 - Acknowledgements Acknowledgements Foremost, I would like to thank Professor Peter O’Hare for his support throughout my PhD and during the post-doctoral application process. There was not a single day when you could not ask him a question or discuss results. I think I speak for everyone in the group (and outside) in that he was always approachable, patient and that I felt well supported at every point during my PhD. The last four years working with present and past members of the group have been a great experience, allowed me to learn many new techniques and made the learning process more manageable. I even started appreciating the calming influence of classical music. I would also like to thank Dr Fernando Abaitua for his help during my first year and the very detailed discussions during the early morning hours, even after having left our group over two years ago. A big ‘thank you’ and ‘sorry’ also goes to Dr Sonia Barbosa, who could usually not escape these elaborate discussions in a timely fashion, to Dr Remi Serwa, who performed the mass spectrometry, and Nora Schmidt, who had the pleasure of reading and commenting on my thesis. I was supported by two very helpful assessors, Dr Goedele Maertens and Professor Wendy Barclay, who were always happy to advise me on any issues that arose from the work presented here.
