Poly(ADP-ribose): an organizer of cellular architecture.

Published: June 2014

Distinct properties of poly(ADP-ribose)-including its structural diversity, nucleation potential, and low complexity, polyvalent, highly charged nature-could contribute to organizing cellular architectures. Emergent data indicate that poly(ADP-ribose) aids in the formation of nonmembranous structures, such as DNA repair foci, spindle poles, and RNA granules. Informatics analyses reported here show that RNA granule proteins enriched for low complexity regions, which aid self-assembly, are preferentially modified by poly(ADP-ribose), indicating how poly(ADP-ribose) could direct cellular organization.

The femtosecond dynamics of energy transfer from light-excited spirilloxanthin (Spx) to bacteriochlorophyll (BChl) a in the reaction centers (RCs) of purple photosynthetic bacteria Rhodospirillum rubrum was studied. According to crio-electron microscopy data, Spx is located near accessory BChl a in the B-branch of cofactors. Spx was excited by 25 fs laser pulses at 490 nm, and difference absorption spectra were recorded in the range 500-700 nm.

We aimed to assess the impact of splicing variants reported in our laboratory to gain insight into their clinical relevance. A total of 108 consecutive individuals, for whom 113 splicing variants had been reported, were selected for RNA-sequencing (RNA-seq), considering the gene expression in blood. A protocol was developed to perform RNA extraction and sequencing using the same sample (dried blood spots, DBS) provided for the DNA analysis, including library preparation and bioinformatic pipeline analysis.

Targeted protein degradation (TPD) offers a promising approach for chemical probe and drug discovery that uses small molecules or biologics to direct proteins to the cellular machinery for destruction. Among the >600 human E3 ligases, CRBN and VHL have served as workhorses for ubiquitin-proteasome system-dependent TPD. Identification of additional E3 ligases capable of supporting TPD would unlock the full potential of this mechanism for both research and pharmaceutical applications.

College of Mathematics and Computer Science, Guangdong Ocean University, Zhanjiang, 524088, China.

To address the problems of complex cloud features in satellite cloud maps, inaccurate typhoon localization, and poor target detection accuracy, this paper proposes a new typhoon localization algorithm, named TGE-YOLO. It is based on the YOLOv8n model with excellent high-low feature fusion capability and innovatively achieves the organic combination of feature fusion, computational efficiency, and localization accuracy. Firstly, the TFAM_Concat module is creatively designed in the neck network, which comprehensively utilizes the detailed information of shallow features and the semantic information of deeper features, enhancing the fusion ability of features at each layer.

Bioaugmented slurry technology is a sustainable remediation technology for PAHs-contaminated soil. However, the lack of experimental data on the remediation of complex, actual contaminated soils has hindered the practical application of this technology. This study explored the bioaugmented degradation of PAHs using actual soil slurry with and without the addition of microbial agents in the microscopic world.
