Host microbiome in relation to Barretts esophagus and esophageal adenocarcinoma development

Supervisor: doc. RNDr. Petra Bořilová Linhartová, Ph.D., MBA

OBJECTIVES: Along with individuals genetic predisposition, host microbiome is an important factor in etiopathogenesis of gastroesophageal reflux disease (GERD), increasing significantly risk of developing esophagitis (RE), Barretts esophagus (BE), and esophageal adenocarcinoma (EAC). The project aim is to determine markers at the level of microbiome, host genes and their interactions for earlier diagnosis/prediction of BE and EAC The project includes analyses of (1) metagenome and metatranscriptome at several sites of gastrointestinal tract (GIT) in GERD patients, (2) host exome and transcriptome in esophageal tissue in patients with BE/EAC, and (3) genetic profile of GERD patients. Mutations in patients exome/genome and gene expression levels in esophagus tissue will be correlated with microbiome.

FOCUS: The main objective of the study is to verify the applicability of molecular biologal approaches in the diagnosis and prediction of GERD complications, such as BE and EAC. Following our pilot data, an analysis of the upper GIT microbiome will be performed under physiological and pathological conditions, which may contribute to earlier diagnosis and optimization of the algorithm for secondary prevention measures in the development and treatment of BE and EAC in patients with GERD. The partial aims of the project: (1a) determination of microbiome in the oral cavity, esophagus, stomach and duodenum by metagenome sequencing method - and correlation with the results of Helicobacter pylori determined using qPCR 16S rRNA and/or culturing of this bacterium from biopsy tissue in patients with RE, with BE and with EAC. In the selected patients with BE and EAC in esophageal tissue with pathological findings vs without pathological findings we will perform: (1b) determination of bacterial transcriptome using sequencing techniques, (2a) analysis of selected parts of exome, and (2b) analysis of expression of selected genes. Further, we plan: (3a) to determine genetic predisposition from blood of the patients with RE, BE and EAC by determining the variability in specific genes involved in the function of the immune system and carcinogenesis.

Characterization of hyaluronidase isolated from the fungus Talaromyces stipitatus

Supervisor: doc. RNDr. Petr Skládal, CSc.

Hyaluronan(HA) je lineární polysacharid z disacharidických jednotek kyseliny D-glukuronové a D-N-acetylglukosaminem. HA je štěpen na kratší fragmenty dvěma typy enzymů. Savčí hyaluronidázy hydrolyticky štěpí řetězce za vzniku menších fragmentů z nezměněných monosacharidů. Mikroorganismy produkují hyaluronan lyázy, které rovněž štěpí řetězce hyaluronanu beta–eliminační reakcí, při které na neredukujícím konci fragmentu vzniká kyselina glukuronová s dvojnou vazbu mezi C4 a C5. Houba Talaromyces stipitatus produkuje hyaluronidázu (TsHr), která štěpí hydrolyticky 1,4 glykosidickou vazbu. Ačkoli svojí primární strukturou je savčím hyaluronidázám podobná jen vzdáleně, patří do rodiny hydroláz glykosidických vazeb GH16, konečnými produkty jsou krátké fragmenty ze 4 až 6 monosacharidů. Předběžné výsledky s rekombinantní TsHr ukazují, že dokáže štěpit deriváty HA savčím enzymem neštěpitelné. TsHr je strukturně příbuzný s transglykosylázami, které patří do stejné rodiny. To by mohlo být využitelná v chemoenzymatických syntézách derivátů HA s definovanou polohou substituentů.
Cílem první části studia bude přispět k poznání TsHr po stránce kinetiky i mechanismu enzymatické reakce a porovnat získané výsledky se savčí bovinní testikulární hyaluronidázou. Bude studována inhibice TsHr různě dlouhými a modifikovanými fragmenty hyaluronanu. Poté by mělo být rozhodnuto, zda enzym TsHr spolu s dalšími enzymy bude využitelný při stanovování rozložení substituentů na řetězci derivátů HA. U savčích hydroláz byla prokázána transglykosylační aktivita - spojování kratších fragmentů HA na delší řetězce. Nikdo však neprokázal, že je to možné u fragmentů substituovaných vybranými substituenty v určitých polohách. Pokud se prokáže, že enzym TsHr není tak citlivý na substituci hyaluronanu jako savčí enzymy, bude zkoumána transglykosylační aktivita a případně hledány podmínky pro využití při syntéze derivátů HA.
Enzym štěpí vysokomolekulární hyaluronan na kratší fragmenty, čímž vytváří koktejl kratších fragmentů hyaluronanu v reakční směsi. Tyto nově vzniklé fragmenty jsou rovněž štěpeny hyaluronidázou, avšak pravděpodobně s jinými kinetickými parametry. Ve výsledku by se tento stav mohl jevit jako inhibice substrátem/produktem. V savčích organismech by toto mohla být cesta regulující rychlost degradace hyaluronanu ve tkáních. Toto by mohlo přispět jednak k potvrzení potenciální regulační role fragmentů a k poznání rozdílů mezi houbovým a savčím enzymem. Navíc v literatuře se popisují interakce různých fragmentů HA se savčím enzymem, které se odehrávají mimo aktivní centrum - projevuje se změnou kinetických parametrů.

Identification of changes in glutamatergic pathways specific for sporadic form of Alzheimer's disease in human astrocytes

Supervisor: doc. Mgr. Jan Lochman, Ph.D.

OBJECTIVE: Neurodegenerative foldopathies represent a group of human protein-misfolding disorders that are characterized by a pathological alteration in conformation of a native protein which makes it resistant to degradation and leads to pathological gain and loss of function. These are followed by aggregation of the misfolded proteins into insoluble deposits. One of the most prominent protein-misfolding disorders is AD. The number of patients suffering dementia in the Czech Republic is estimated at 160 thousand. Up to two-thirds of cases are due to Alzheimer's disease, others include, for example, vascular dementia, Parkinson's disease or other degenerative brain disorders.

FOCUS: In neurodegenerative disorders (including Alzheimer's disease, AD) astrocytes/astroglia undergo complex changes that range from atrophy with loss of function to accumulation of reactive cells around disease-specific lesions (senile plaques in the case of AD). The cellular pathology of astrocytes in the context of human AD remains enigmatic; mainly because of severe limitations of animal models, which, although reproducing some pathological features of the disease, do not mimic its progression in full. The human induced pluripotent stem cells (hiPSCs) technology creates a novel and potentially revolutionizing platform for studying fundamental mechanisms of the disease and for screening to identify new therapeutic compounds.

EXAMPLE of a potential doctoral project - the student will focus on: Suitable procedures for studying early pathology of Alzheimer's disease (AD) are currently being sought. The main aim of the project is to create a model of cell cultures suitable for monitoring changes in the biology of nerve cells (neurons and astrocytes) in patients with AD. Using the induced pluripotent cell method (iPSC), the role of nerve cells in the formation of sporadic form of AD will be studied.

    The specific aims are following:
  • Analysis of DEGs (differently expressed genes) between patients and controls and measured physiological parameters in and between groups.
  • Analysis of DEGs (differently expressed genes) between patients and controls and measured physiological parameters in and between groups.
  • Verification of selected differences in genes expression by qPCR analysis.
  • Verification of very promising candidate genes expression by Western Blot.
  • Analysis of selected neurotransmitters by LC-MS/MS.
