2. 1. Roles of LESIONS SIMULATING DISEASE1 and Salicylic Acid in Acclimation of Plants to Environmental Cues : Redox Homeostasis and physiological processes underlying plants responses to biotic and abiotic challenges

   Author : Alfonso Mateo; Stanislaw Karpinski; Philip M. Mullineaux; John F. Allen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LSD1; Photooxidative stress; Reactive oxygen species; Light acclimation; Photorespiration; Salicylic acid; Plant physiology; Växtfysiologi;

   Abstract : In the natural environment plants are confronted to a multitude of biotic and abiotic stress factors that must be perceived, transduced, integrated and signaled in order to achieve a successful acclimation that will secure survival and reproduction. Plants have to deal with excess excitation energy (EEE) when the amount of absorbed light energy is exceeding that needed for photosynthetic CO2 assimilation. READ MORE

4. 2. Genetic and Molecular Mechanisms Controlling Reactive Oxygen Species and Hormonal Signalling of Cell Death in Response to Environmental Stresses in Arabidopsis thaliana

   Author : Per Mühlenbock; Stanislaw Karpinski; Barbara Karpinska; Pierre Frendo; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi;

   Abstract : In the present work the regulation of environmentally induced cell death and signaling of systemic acquired acclimation (SAA) in Arabidopsis thaliana is characterized. We used the lesion simulating disease1 (lsd1) mutant as a model system that is deregulated in light acclimation and programmed cell death (PCD). READ MORE

5. 3. Development of Peptide Binders : Applied to Human CRP, Carbonic Anhydrase (II, IX) and Lysine Demethylase 1

   Author : Jie Yang; Jan Kihlberg; Morten Grötli; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polypeptide conjugates; molecular recognition; peptide cyclization; protein targets;

   Abstract : In this thesis, a polypeptide binder concept is illustrated. By conjugation to a set of sixteen polypeptides, a small binding molecule can evolve into a polypeptide binder with increased affinity and selectivity. READ MORE

6. 4. Dissecting gene expression regulation in mouse embryonic stems

   Author : Sandhya Malla; Francesca Aguilo; Filipe Pereira; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molekylärbiologi; Molecular Biology;

   Abstract : Every cell within an organism is derived from a single fertilized egg that undergoes cellular differentiation and development to generate mature specialized cells. Mouse embryonic stem cells (ESCs) derived from the inner cell mass (ICM) of the pre-implantation blastocyst have proven to be a model to study gene expression during differentiation and development.

7. 5. Transcriptional and post-transcriptional regulation of telomerase reverse transcriptase (hTERT) expression : the role of histone modification and alternative splicing

   Author : Zheng Ge; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Telomerase, an RNA-dependent DNA polymerase responsible for telomeric DNA elongation, is silent in most normal differentiated human cells due to the tight repression of its catalytic unit, telomerase reverse transcriptase (hTERT), whereas constitutive hTERT expression and telomerase activation are prerequisites for cellular immortalization/malignant transformation. As reconfiguration of chromatin acts like a master on/off switch, determining whether particular genes are active or inactive, the project was specifically designed to first elucidate molecular strategies that integrate diverse signalling pathways at the hTERT chromatin and consequently result in telomerase activation or repression in normal and malignant human cells.
