Like other eukaryotic organisms, Toxoplasma gondii promoters feature both constitutive and life-stage regulated cis-elements. Using a transcriptomic microarray approach, a cluster of transcripts upregulated early during bradyzoite differentiation was identified. Computational analysis of the promoter regions of these “up-early” transcripts identified a shared upstream consensus motif, a putative transcription factor binding site. Using a dual luciferase assay adapted for recombinational cloning and reporter gene quantification by qPCR, we demonstrate developmental stage-specific expression of the luciferase reporter gene inserted downstream of the transcription factor binding site. The shared consensus motif was found to be an autonomous cis-element by conversion …

Pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States, and 95% of these cases are caused by PDAC (pancreatic ductal adenocarcinoma). Ketone bodies have previously been shown to decrease cell proliferation and cancer-induced cachexia. The molecular mechanism of ketone body-mediated growth inhibition of pancreatic cancer cells is not well understood. Research conducted thus far has not explored which molecular pathways are affected by ketone body treatment in pancreatic cancer cells. In the current study, the effect of the ketone body sodium hydroxybutyrate on the JAK-STAT and mTOR pathways and cell migration was explored. A decrease …
