S100A9, a calcium-binding protein, participates in the inflammatory process and development of various tumors, thus attracting much attention in the field of cancer biology. This study aimed to investigate the regulatory mechanism of and its function involvement in APL. We used real-time quantitative PCR to determine whether PML/RARα affects the expression of in NB4 and PR9 cells upon ATRA treatment. ChIP-based PCR and dual-luciferase reporter assay system were used to detect how PML/RARα and PU.1 regulate promoter activity. CCK-8 assay and flow cytometry were employed to observe the viability and apoptosis of NB4 cells when was overexpressed. Results showed that was an ATRA-responsive gene, and PML/RARα was necessary for the ATRA-induced expression of in APL cells. In addition, PU.1 could bind to the promoter of , especially when treated with ATRA in NB4 cells, and promote its activity. More importantly, overexpression of induced the apoptosis of NB4 cells and inhibited cell growth. Collectively, our data indicated that PML/RARα and PU.1 were necessary for the ATRA-induced expression of in APL cells. Furthermore, promoted apoptosis in APL cells and affected cell growth.

Cholesterol plays a significant role in the organization of lipids and modulation of membrane dynamics in mammalian cells. However, the effect of cholesterol depletion on the eukaryotic cell membranes seems controversial. In this study, the effects of cholesterol on the topography and mechanical behaviors of CHO-K1 cells with manipulated membrane cholesterol contents were investigated by atomic force microscopy (AFM) technique. Here, we found that the depletion of cholesterol in cell membranes could increase the membrane stiffness, reduce the cell height as well as promote cell retraction and detachment from the surface, whereas the cholesterol restoration could reverse the effect of cholesterol depletion on the membrane stiffness. Increased methyl-β-cyclodextrin levels and incubation time could significantly increase Young’s modulus and degree of stiffing on cell membrane and cytoskeleton. This research demonstratede importance of cholesterol in regulating the dynamics of cytoskeleton-mediated processes. AFM technique offers excellent advantages in the dynamic monitoring of the change in membranes mechanical properties and behaviors during the imaging process. This promising technology can be utilized in studying the membrane properties and elucidating the underlying mechanism of distinct cells in the near-native environment.

Microbial responses to combined oxidation and catalysis treatment of 1,4-dioxane and co-contaminants

Groundwater microbial community was altered after catalysis and chemical oxidation. The coupled treatment train removed 90% 1,4-dioxane regardless of co-contaminants. Dynamics of microbial populations varied along with different treatment stages. Many microbial taxa exhibited resilience against oxidative and catalytic treatments. Metagenomic analysis will be valuable for long-term management of polluted sites.
