The antimicrobial effect of a novel peptide LL-1 on Escherichia coli by increasing membrane permeability by Lingling Zhou, Kaiqi Lian, Mengting Wang, Xueyi Jing, Yuanchen Zhang, Jinling Cao

“…The influence of LL-1 on the intracellular ATP of E. coli was analysed by determining the concentration of intracellular ATP. Finally, the bacteria and colonies of E. coli treated with LL-1 were observed using scanning and transmission electron microscopy. …”

How much (ATP) does it cost to build a trypanosome? A theoretical study on the quantity of ATP needed to maintain and duplicate a bloodstream-form Trypanosoma brucei cell. by Janaina F Nascimento, Rodolpho O O Souza, Mayke B Alencar, Sabrina Marsiccobetre, Ana M Murillo, Flávia S Damasceno, Richard B M M Girard, Letícia Marchese, Luis A Luévano-Martinez, Renan W Achjian, Jurgen R Haanstra, Paul A M Michels, Ariel M Silber

“…Flagellar motility, variant surface glycoprotein recycling, transport and maintenance of transmembrane potential account for less than 30% of the consumed ATP. Finally, there is still ~5.5% available in the budget that is being used for other cellular processes of as yet unknown cost. …”

ATP Induces Interleukin-8, Intracellular Calcium Release, and ERK1/2 Phosphorylation in Bovine Endometrial Cells, Partially through P2Y Receptors by Noemí Gutierrez, Stefanie Teuber, Pablo Alarcon, Rafael A. Burgos, María A. Hidalgo

“…Suramin (50 μM), a pan-antagonist of P2Y receptors, partially reduced the intracellular calcium mobilization, ERK1/2 phosphorylation (ratio 0.83 ± 0.08, <i>p</i> = 0.045), and IL-8 release (9.67 ± 0.02 pg/mL, <i>p</i> = 0.014) induced by ATP. Finally, BEND cells expressed higher mRNA levels of P2Y1 and P2Y2 purinergic subtype receptors, and lower levels of P2Y11 and P2Y12 receptors, as determined by RT-qPCR. …”
