Putative RNA Ligase RtcB Affects the Switch between T6SS and T3SS in Pseudomonas aeruginosa

The opportunistic pathogen Pseudomonas aeruginosa is a significant cause of infection in immunocompromised individuals, cystic fibrosis patients, and burn victims. To benefit its survival, the bacterium adapt to either a motile or sessile lifestyle when infecting the host. The motile bacterium has an often activated type III secretion system (T3SS), which is virulent to the host, whereas the sessile bacterium harbors an active T6SS and lives in biofilms. Regulatory pathways involving Gac-Rsm or secondary messengers such as c-di-GMP determine which lifestyle is favorable for P. aeruginosa. Here, we introduce the RNA binding protein RtcB as a modulator of the switch between motile and sessile bacterial lifestyles. Using the wild-type P. aeruginosa PAO1, and a retS mutant PAO1(∆retS) in which T3SS is repressed and T6SS active, we show that deleting rtcB led to simultaneous expression of T3SS and T6SS in both PAO1(∆rtcB) and PAO1(∆rtcB∆retS). The deletion of rtcB also increased biofilm formation in PAO1(∆rtcB) and restored the motility of PAO1(∆rtcB∆retS). RNA-sequencing data suggested RtcB as a global modulator affecting multiple virulence factors, including bacterial secretion systems. Competitive killing and infection assays showed that the three T6SS systems (H1, H2, and H3) in PAO1(∆rtcB) were activated into a functional syringe, and could compete with Escherichia coli and effectively infect lettuce. Western blotting and RT-PCR results showed that RtcB probably exerted its function through RsmA in PAO1(∆rtcB∆retS). Quantification of c-di-GMP showed an elevated intracellular levels in PAO1(∆rtcB), which likely drove the switch between T6SS and T3SS, and contributed to the altered phenotypes and characteristics observed. Our data demonstrate a pivotal role of RtcB in the virulence of P. aeruginosa by controlling multiple virulence determinants, such as biofilm formation, motility, pyocyanin production, T3SS, and T6SS secretion systems towards eukaryotic and prokaryotic cells. These findings suggest RtcB as a potential target for controlling P. aeruginosa colonization, establishment, and pathogenicity

Tuning the morphology of g-C3N4 for improvement of Z-scheme photocatalytic water oxidation

Solar-driven water oxidation is the key step for overall water splitting that efficiently harvests and converts solar energy into fuels; the development of a highly efficient photocatalyst that can mediate water oxidation has become an appealing challenge. Herein, we report a facile two-step process to decorate silver phosphate (Ag3PO4) particles on different types of graphitic carbon nitrides (g-C3N4) as composite photocatalysts for water oxidation. For all the (Ag3PO4)/g-C3N4 materials, an in situ Z-scheme is created by the generation of Ag nanoparticles which act as a cross-linking bridge between (Ag3PO4) and g-C3N4 in the composite, resulting in better charge separation and higher catalytic performance. A detailed analysis emphasizes the importance of the g-C3N4 on the chemical, photophysical, and catalytic properties of the composite materials. Our results show that the alteration of the morphology dominates the performance of the composite materials

Emerging signals regulating liver tumor initiating cells

Tumor initiating cells (TICs) have been identified as cells that account for tumor heterogeneity. Recent studies demonstrated that genes controlling stem cell biology play key roles in maintaining TICs and promote their development into cancer. In this review, we summarize findings from human and animal studies that indicate the presence of TICs during liver cancer development. Markers identified for liver development and regeneration are used to identify liver cancer TICs. Expression of these markers is often upregulated in human hepatocellular carcinoma (HCC) specimen. Using flow cytometry analysis and lineage tracing approaches, the presence of TICs is confirmed. Expression of TIC markers and the presence of TICs are also observed in genetically modified animals that target genes that are frequently altered in human HCC. The presence of these TICs represents a major challenge for therapeutic development. Elucidating signals that can regulate the fate, transformation and growth of liver TICs is an emerging need in liver research. Sex-determining region Y-box 9 (SOX9) has recently become an important marker for liver TICs. Here, we summarize the role of SOX9 in TICs and its potential interaction with other signals. This includes the Notch-Numb signal that controls asymmetrical-symmetrical cell division, Wnt-β-catenin signal that maintains cell fate and transforming growth factor (TGF)-β signal that acts as upstream inducers. Keywords: Liver cancer, Hepatocellular carcinoma (HCC), Tumor initiating cells (TICs), Sex-determining region Y-box 9 (SOX9), β-catenin, Notch, Numb, Transforming growth factor (TGF)-

How firm heterogeneity affects foreign direct investment location choice: Micro-evidence from new foreign manufacturing firms in the Pearl River Delta

This study explores how firm heterogeneity affects the geographic agglomeration and location choice of foreign direct investment (FDI) based on micro-evidence from 3558 new foreign manufacturing firms in the Pearl River Delta, China. Kernel density and categorical multivariate linear regression are integrated to examine FDI location choices. The empirical results confirm that firm location choices are jointly influenced by location factors and firm heterogeneity. Specifically, we find that a firm's location decisions and agglomeration behavior are determined by the interaction between firm heterogeneity and location factors. Although location factors reveal a significant impact on the entry decisions of firms, the location effects are adjusted to some extent, or even change direction, when firm heterogeneity factors are taken into consideration. Investment from different origins via different entry modes and different sectoral composition in the same host location exhibits different nature of clustering, which may be interpreted as different characteristics of interaction between home and host regions in the context of the global economy. Such insights into the heterogeneity of firms with their divergent ways in choosing their locations also echo with the previous discussion on 'divergent capitalism'. We believe that a better understanding of the impact of firm heterogeneity on FDI location choices at the micro-level can help policy-makers formulate more appropriate firm-based policies. Such policies could address the specific preferences of different types of firms

Microstructure and Friction Properties of AlCrTiVNb_x High-Entropy Alloys via Annealing Manufactured by Vacuum Arc Melting

To enhance the friction and wear properties of alloys, AlCrTiVNbx high-entropy alloys (HEAs) with various Nb contents were prepared using the arc melting technique and then annealed at 1000 °C for 2 h. The microstructure and hardness changes in the AlCrTiVNbx (x = 0.3, 0.4, and 0.5) HEAs after casting and annealing were studied via scanning electron microscopy, X-ray diffractometry, optical microscopy and the Vickers hardness test. The MFT-EC400 ball disc reciprocating friction and wear tester was used to investigate the wear resistance of the HEAs before and after annealing. The results show that the annealed AlCrTiVNbx HEAs changed from a single-phase structure to a multi-phase structure, and the content of the face-center cubic (FCC) phase and hexagonal close-packed (HCP) phase further increases with the increase in Nb content. The hardness value of the annealed HEAs is greatly enhanced compared with the casting state, and the hardness of the Nb0.5 HEA is increased from 543 HV to 725 HV after annealing. The wear resistance of the alloys after the annealing treatment is also greatly improved, among which Nb0.5 has the best wear resistance. The average friction coefficient of Nb0.5 is 0.154 and the wear rate is 2.117 × 10−5 mm3/(N·m). We believe that the precipitation strengthening after the annealing treatment and the lubrication effect of the FCC phase are the reasons for the significant improvement in wear resistance. The morphology of the samples indicates that the wear mechanism of the alloy includes adhesive wear, abrasive wear and a certain degree of oxidation wear
