Molecular Mechanism Of Action Of The Natural Polyphenolic Compound And The P300 Inhibitor “Carnosol” Against The Triple Negative Breast Cance, Halima Ali Mohammed Salem Alsamri Nov 2021

Molecular Mechanism Of Action Of The Natural Polyphenolic Compound And The P300 Inhibitor “Carnosol” Against The Triple Negative Breast Cance, Halima Ali Mohammed Salem Alsamri

Dissertations

Carnosol, a naturally occurring Phyto polyphenol found in sage, oregano, and rosemary, has been extensively studied by our laboratory for its anticancer effects in various types of cancer. In human Triple-Negative Breast Cancer (TNBC), carnosol was shown to inhibit cellular viability, colony growth, induced cell cycle arrest, autophagy, and apoptosis. Nonetheless, very little is known about the molecular mechanism of action. In the current study, the ability of carnosol to inhibit metastasis and tumour growth was examined. Wound healing and invasion assays revealed that carnosol inhibited migration and invasion at non-cytotoxic concentrations of MDA-MB-231 cells. Also, carnosol was found to …


The Role Of Nutrient Sensitive Protein O-Glcnacylation In Developmental Cortical Neurogenesis, Shama Parween Jun 2021

The Role Of Nutrient Sensitive Protein O-Glcnacylation In Developmental Cortical Neurogenesis, Shama Parween

Dissertations

The nutrient responsive O-GlcNAcylation is a dynamic, posttranslational protein modification present on many nucleocytoplasmic and mitochondrial proteins. Previous research has indicated that hyperglycaemia increases the levels of total O-GlcNAcylation within cells. Transcription factors and histones are among hundreds of proteins that have been reported to be O-GlcNAcylated and have importance in cell fate determination during cell growth, proliferation, and differentiation. However, the role of protein O-GlcNAcylation in epigenome control in response to nutritional perturbations is poorly understood. Hyperglycaemia induced protein O-GlcNAcylation have been linked to several pathologies, including obesity, diabetes, cancer, cardiovascular and neurodegenerative diseases. …


Lipocalin-2 Ameliorates The Signs And Outcomes Of Diabetes Mellitus In An Animal Model, Saeeda Mohammed Al Jaberi Jun 2021

Lipocalin-2 Ameliorates The Signs And Outcomes Of Diabetes Mellitus In An Animal Model, Saeeda Mohammed Al Jaberi

Theses

Lipocalin-2 (LCN2) is a new adipocytokine consisting of 198 amino acids. It is also referred to as neutrophil gelatinase-associated lipocalin, siderocalin, uterocalin, α1-microglobulin related protein, or 24p3. LCN2 belongs to a large group of transport proteins that are capable of carrying small and lipid-soluble molecules in blood circulation. It has two membrane receptors, megalin/glycoprotein GP330, which binds human LCN2 and SLC22A17 or 24p3R, which forms complexes with mouse Lcn2 protein. LCN2 is encoded by a gene located at chromosome locus 9q34.11. LCN2 was initially isolated from neutrophil granules released at the site of infection and inflammation in humans and from …
