Applied Drug Development And Combinatorial Strategies For Antimicrobial Treatment, Steven K. Lai Hing
Applied Drug Development And Combinatorial Strategies For Antimicrobial Treatment, Steven K. Lai Hing
Andrews Research Conference
Streptococcus mutans JH1140 is a strain of bacteria which produces a lantibiotic product, named mutacin 1140. Mutacin 1140 has been shown to be effective at inhibiting Gram-positive bacterial infections caused by Staphylococcus aureus and Streptococcus pneumoniae. Mutacin 1140 is a ribosomally synthesized peptide antibiotic that undergoes extensive posttranslational modifications (PTM). We have found that Mutacin 1140 and an aminoglycoside, Kanamycin, when combined together, act synergistically against Staphylococcus aureus. This was determined by performing serial kill curve dilution overlays on solid media, followed up with kill curve by microdilution plate, and most recently confirmed with kill curve CFU count plates …
Therapeutic Modulation Of Cancer Metabolism With Dichloroacetate And Metformin, Nathan Patrick Ward
Therapeutic Modulation Of Cancer Metabolism With Dichloroacetate And Metformin, Nathan Patrick Ward
USF Tampa Graduate Theses and Dissertations
The robust glycolytic metabolism of glioblastoma multiforme (GBM) has proven them susceptible to increases in oxidative metabolism induced by the pyruvate mimetic dichloroacetate (DCA). Recent reports demonstrate that the anti-diabetic drug metformin enhances the damaging oxidative stress associated with DCA treatment in cancer cells. We sought to elucidate the role of metformin’s reported activity as a mitochondrial complex I inhibitor in the enhancement of DCA cytotoxicity in the VM-M3 model of GBM. We demonstrated that metformin potentiated DCA-induced superoxide production and that this was required for enhanced cytotoxicity towards VM-M3 cells with the combination. Similarly, rotenone enhanced oxidative stress resultant …
Patholigical And Prognostic Role Of Mdig In Pancreatic Cancer, Srinivas Ashok Kumar
Patholigical And Prognostic Role Of Mdig In Pancreatic Cancer, Srinivas Ashok Kumar
Wayne State University Theses
Pancreatic cancer is a highly aggressive malignant disease having very limited therapeutic options that ultimately results in its poor prognosis. It is still elusive on the etiology and tumorigenic mechanisms of pancreatic cancer. In the present report, we provide evidence showing involvement of the mineral dust-induced gene (mdig) in the pathogenesis and prognosis of the pancreatic cancer. Using immunohistochemistry approach on human pancreatic cancer tissue microarray, we found differential expression of mdig in pancreatic adenocarcinoma and normal pancreas. Based on the staining intensities of mdig in these tissue samples, we found that 12% of the cancer tissues were strongly positive …
Effects Of Antibiotic Treatment On The Expression Of Hepatic And Intestinal Cytochrome P450, Bruno Pereira De Carvalho
Effects Of Antibiotic Treatment On The Expression Of Hepatic And Intestinal Cytochrome P450, Bruno Pereira De Carvalho
Legacy Theses & Dissertations (2009 - 2024)
Expression of metabolic enzymes Cytochrome P450 (CYP) is highly affected by drugs, diseases, age and gender. The Intestinal microflora has been suggested to play a role in regulating CYP expression and antibiotic treatments would lead to changes in level and composition of microbiota in mouse gut. This study aims to analyze CYP expression changes in the liver and small intestine resulted from the reduction of intestinal microflora by antibiotics. Impacts on bile acid signaling were also analyzed for a better comprehension of the mechanisms involved in this modulation. Female C57BL/6J mice (9- to 13-week old) were treated with ampicillin (AMP) …
