Role Of Pu.1 And C/Ebpα In Remodelling The Interleukin (Il)-1Β Enhancer-Promoter Interaction, Woohyun Cho, Soon-Duck Ha, Sung Ouk Kim

Western Research Forum

Background: IL-1b is a potent inflammatory cytokine promptly expressed in activated myeloid immune cells. Among various transcription factors, PU.1 and CCAAT/enhancer-binding protein alpha (C/EBPa) play a key role in the lineage commitment of myeloid cells. To date, however, the exact mechanisms by which these lineage-determining transcription factors employ to regulate the expression of myeloid-specific genes remains elusive; thus, this study explores the role of PU.1 and C/EBPa in remodelling the chromatin conformation that allows ample production of IL-1b.

Methods: To examine the mechanism of these lineage-determining transcription factors, production of IL-1b and enhancer-promoter interactions were analyzed in non-myeloid B16-BL6 cells …

Doxycycline Resistance In Plasmodium Falciparum Linked To Single Nucleotide Polymorphisms In The Plasmodium Falciparum Apicoplast Small Subunit Ribosomal Rna (Pfssrrna) Gene, Amanda Wasko

Scholarly and Creative Works Conference (2015 - 2021)

Plasmodium falciparum, a protozoan parasite known as malaria, widely impacts human health; thus antimalarial drug investigations are critical. Doxycycline is a commonly used antimalarial prophylactic, but its mechanism of action is unclear. In prokaryotes, doxycycline works as an antibacterial by disrupting protein translation via the small subunit ribosome. Interestingly, P. falciparum has a small subunit ribosome of prokaryotic origins in the apicoplast, a plastid-like organelle. Therefore, we hypothesized that doxycycline works in P. falciparum by inhibiting protein synthesis via the small subunit ribosomal RNA and that mutations in the gene encoding the P. falciparum apicoplast small subunit ribosomal RNA …

The Release Of Calcium In Bacillus Anthracis Pathogenicity Methods, Natiera Magnuson, Manomita Patra Bhowmik, Maria Elena Reynaga, Ernesto Abel-Santos

Festival of Communities: UG Symposium (Posters)

Anthrax infection starts with germination of Bacillus anthracis spores in macrophages. Some bacteria, including B. anthracis, can sporulate in response to environmental stress, such as starvation. During germination, large concentrations of calcium ions are released from the B. anthracis spore. Calcium ions are hydrophilic secondary messengers, and may therefore interfere with detection of the spore by confusing the cell signaling pathways. We investigated calcium release on infected macrophage viability by replacing the calcium stored in B. anthracis spores for other cations via demineralization/remineralization. It was discovered that calcium ions typically out-performed other cations in germination of B. anthracis.
