Data_Sheet_1_Structural Characteristics and Functional Implications of PM2.5 Bacterial Communities During Fall in Beijing and Shanghai, China.docx
Air pollution characterized by fine particulate matter (PM2.5) frequently has occurred in China, and has posed threats to human health. The physiochemical characteristics of airborne PM2.5 have been extensively studied, but its bacterial structures and functions have not yet been well studied. Herein, we focused on the structural characteristics and functional implications of airborne bacteria under different pollution levels in Beijing and Shanghai. The α- and β-diversities showed no obvious difference in two cities (p > 0.05). The dominant phyla Proteobacteria, Firmicutes, and Actinobacteria with total abundance of over 92% were found in all PM2.5 samples. The results of weighted unifrac non-metric multidimensional scaling (NMDS) suggested that air pollution was no obviously correlated with bacterial community but dispersed disorderly. Furthermore, canonical correlation analysis (CCA) and permutation test indicated that NH4+, SO42-, and wind speed were the key factors that associated with airborne bacterial community structure. Chemical components of particulate matter played more important role in structuring bacterial community than meteorological conditions based on the result of partial CCA. In addition, the annotation of metabolic pathway suggested that the predominant genus Pseudomonas was obviously correlated with disease infections. Several dominant species might contribute to organic degradation, nitrogen cycles, and ice-nuclei activities in environments. Overall, this work enhanced our understanding of functions of airborne bacteria and highlighted their potential role in atmospheric chemical progresses.</p

EGFR promotes the proliferation of quail follicular granulosa cells through the MAPK/extracellular signal-regulated kinase (ERK) signaling pathway
Follicles develop into preovulatory follicles during folliculogenesis and the majority of small yellow follicles become atretic and gets reabsorbed. In this study, based the RNA-seq results of duck ovary, epidermal growth factor receptor (EGFR) was selected as a candidate gene in follicular development and the role was explored. The results demonstrated that EGFR-P8 was the quail EGFR core promoter. It had an E2F4 binding site within EGFR core promoter. E2F4 overexpression significantly increased EGFR expression in quail granulosa cells (GCs). However, the effect was abolished when the GCs were treated with corynoxeine, an inhibitor of the mitogen-activated protein kinase/extracellular regulated protein kinase (MAPK/ERK) signaling pathway. Moreover, luciferase reporter assay and chromatin immunoprecipitation experiments showed that E2F4 upregulated the expression of EGFR expression, which increased E2 and P4 production. In addition, EGFR regulated GCs proliferation and affected follicular development. Taken together, our findings suggested that EGFR, which was regulated by E2F4, enhanced the expression of MAPK/ERK pathway components and follicular development. These results provided an important basis for an improved understanding of the MAPK/ERK pathway and new insight into the development of quail follicles.</p
Table4_Multiomic analysis revealed the regulatory role of the KRT14 gene in eggshell quality.XLSX
Background: Eggshell strength and thickness are critical factors in reducing the egg breaking rate and preventing economic losses. The calcite biomineralization process is very important for eggshell quality. Therefore, we employed transcriptional sequencing and proteomics to investigate the differences between the uteruses of laying hens with high- and low-breaking-strength shells.Results: A total of 1,028 differentially expressed genes (DEGs) and 270 differentially expressed proteins (DEPs) were identified. The analysis results of GO terms and KEGG pathways showed that most of the DEGs and DEPs were enriched in vital pathways related to processes such as calcium metabolism, hormone and amino acid biosynthesis, and cell proliferation and apoptosis. Several DEGs and DEPs that were coexpressed at mRNA and protein levels were verified. KRT14 (keratin-14) is a candidate gene (protein) obtained by multiple omics analysis due to the fold difference of KRT14 being the largest. After the overexpression of KRT14 in uterine epithelial cells, the expressions of OC116 (ovocleididin-116), CALB1 (calbindin 1), and BST1 (ADP-ribosyl cyclase 2) were found to be increased significantly, while the expression of OC17 (ovocleididin-17) was found to be decreased significantly.Conclusion: In summary, this study confirms that during normal calcification, there are differences in ion transport between the uterus of hens producing high-breaking-strength eggshells and those producing low-breaking-strength eggshells, which may help elucidate the eggshell calcification process. The KRT14 gene may promote calcium metabolism and deposition of calcium carbonate in eggshells.</p

Photo-Physical Properties of CsPbBr<sub>3</sub> Nanocrystals Adjusted by a Weak Quantum Confinement Effect
Perovskite nanocrystals (NCs) with different sizes, which
are close
to the exciton radius, exhibit a weak quantum confinement effect (QCE)
and have a huge potential in the optoelectronic fields. Herein, CsPbBr3 NCs with radius of 7.2, 9.1, and 10.7 nm have been synthesized,
and their photo-physical properties have been investigated in detail.
The carrier decay behavior, involving the monomolecular exciton recombination
and biexciton Auger recombination process, is observed in the CsPbBr3 NCs, and they are affected by the energy dissipation process
related to phonon energy in perovskite NCs, in which the contribution
of weak QCE has been analyzed. The spectral characteristics affected
by pressure show that the phase transition from cubic phase to orthogonal
phase may happen in the CsPbBr3 NCs and the corresponding
knee point gradually enhances with the weakening of QCE. Moreover,
the step effect of photoluminescence (PL) induced by pressure gradually
broadens at the knee point as the QCE weakens. In addition, the light
wave guiding effect of these CsPbBr3 NCs has been analyzed,
exhibiting that self-absorption effect and the conventional light-wave-guiding
effect can be responsible for the decay of PL at different excitation
positions. Our results analyze the carrier decay, energy evolution,
and light-wave-guiding properties of CsPbBr3 NCs with weak
QCE, which broaden the understanding of CsPbBr3 NCs and
enrich their application in the field of photo-communication
