Gene expression and human oocyte maturation: transcriptional control and post-transcriptional mechanisms based on intercellular signalling via exosomal miRNAs in follicular microenvironment
Lo scopo di questa tesi è la caratterizzazione dei profili di espressione di mRNA e miRNA nel gamete femminile e nel suo microambiente, rispettivamente, in condizioni fisiologiche e non, al fine di i) valutare l'effetto della vitrificazione sul profilo biomolecolare degli ovociti, ii) comprendere …

Cytokines and chemokines in the pathogenesis of low back pain
… IL-1 and TNF-α are only two of a large group of intercellular signalling molecules known as cytokines, and studies investigating the expression of other cytokines in the human IVD are limited. This thesis demonstrates the production of numerous cytokines and chemokines (chemoattractant cytokines) …

The role of stress-derived vesicles in the bystander effect and cancer related cachexia
… lipid bound structures that are involved in intercellular signalling. They are known to be involved in numerous processes within the body, including in disease. One interesting function of EVs appears to be the induction of the bystander effect. The bystander effect refers to the non-targeted …

Diffusion and reaction of nitric oxide in cell cultures
… (NO) is synthesized throughout the body and its intercellular signalling and other functions are necessary for health. However, its mutagenic effects make it a potential cause of cancer, if it is produced at a high enough rate for a sufficient time. Sustained overproduction of NO may occur, for …

Untersuchungen zur Rolle von stress-induzierbaren Lipoxygenase-Aktivitäten in Weizen
… of both the 9-LOX and 13-LOX isoforms within the intercellular signalling network determining the plant defence response.

The impact of hypoxia on out-of-field signalling responses following exposure to modulated irradiation
… of cancer cells. Additional understanding of the signalling responses in hypoxic microenvironments is therefore needed to optimise radiation treatment strategies in the future. <br/>Aim: This study aimed to identify the signalling responses in low dose out-offield regions under oxic and hypoxic …

CsgA, a putative signal molecule of the myxobacterium Stigmatella aurantiaca involved in fruiting : characterization of the csgA gene and influence of csgA inactivation on development
… of molecules involved in cell-cell signalling is needed. The best studied intercellular signal of Myxococcus xanthus is the C signal, which is the gene product of the csgA gene. Using the M. xanthus csgA gene as probe a homologous gene was previously isolated from S. aurantiaca …

A Metabolomics-Based Analysis of Acyl-Homoserine Lactone Quorum Sensing in Pseudomonas aeruginosa
… therein. The las and rhl “quorum sensing” (QS) intercellular communication systems play integral roles in this regulatory network and control the expression of factors important to the bacterium’s ecological fitness, including many secreted factors involved in nutrient acquisition, microbial …
