Table_3_Global Lysine Crotonylation Alterations of Host Cell Proteins Caused by Brucella Effector BspF.xlsx
In Brucella spp., the type IV secretion system (T4SS) is essential for bacterial intracellular survival and inhibition of the host innate immune response. The Brucella T4SS secretes 15 different effectors to escape host immunity and promote intracellular replication. Among them, BspF has a GNAT-family acetyltransferase domain, implying its acetyltransferase activity. We confirmed that BspF has acetyltransferase activity (data not shown) and de-crotonyltransferase activity. However, BspF overexpressed in HEK-293T cells can also enhance octamer crotonylation in vitro. Then we enriched crotonylated proteins and conducted LC-MS to study the crotonylation changes of proteins in HEK-293T cells caused by BspF overexpression. A total of 5,559 crotonylation sites were identified on 1,525 different proteins, of which 331 sites on 265 proteins were significantly changed. We found that Rab9A and RAP1B in proteomics data have a great impact on Brucella survival, so we speculate that BspF may influence the function of host proteins by altering crotonylation, thereby promoting the intracellular propagation of Brucella.</p

Comparison of Different Neural Network Architectures for Plasmonic Inverse Design
The merge between
nanophotonics and a deep neural network has shown
unprecedented capability of efficient forward modeling and accurate
inverse design if an appropriate network architecture and training
method are selected. Commonly, an iterative neural network and a tandem
neural network can both be used in the inverse design process, where
the latter is well known for tackling the nonuniqueness problem at
the expense of more complex architecture. However, we are curious
to compare these two networks’ performance when they are both
applicable. Here, we successfully trained both networks to inverse
design the far-field spectrum of plasmonic nanoantenna, and the results
provide some guidelines for choosing an appropriate, sufficiently
accurate, and efficient neural network architecture
Table_3_Ultrasensitive Detection of Pathogenic Bacteria by Targeting High Copy Signature Genes.XLSX
Bacterial load in clinical samples is relatively low and difficult to detect. Improvements in assay sensitivity will greatly reduce false negative results and contribute to more accurate diagnoses. In the present study, we present a new strategy to improve the sensitivity of a nucleic acid assay by detecting the presence of a multi-copy gene. By using Brucella as a test model, we screened the genome and identified IS711 as a multiple copy gene. Distribution analysis of insertion sequence IS711 among different species and strains showed that each of the strains have 5 to 13 copies of IS711. Compared with the BMEI1001, BMEI0775 and BMEI0027, the assays of high copy genes IS711 showed higher sensitivity and is an ideal high copy signature gene for Brucella. Detection of clinical samples with assays targeting the signature genes showed that IS711 exist in higher concentrations than BMEI1001, BMEI0775 and BMEI0027. In addition, IS711 assay is more sensitive than other signature genes assay. Analysis of several other pathogenic bacteria successfully identified high copy number genes that could be used as signature genes. Therefore, this strategy of targeting high copy signature genes represents a universal strategy for the ultrasensitive detection of bacteria.</p
