Summary: Long noncoding RNAs (lncRNAs) play important roles in biological processes and identifying essential lncRNAs is crucial for disease diagnosis and treatment. Experimental methods for identification are costly and time consuming, thus computational methods can be an alternative approach. This study proposes a method that combines network centrality measures and lncRNA sequence information to identify essential lncRNAs and finds that network information significantly improves the predictive performance of sequence-based methods.

Summary: This study reveals that catabolic enzyme expression in E. coli cells continuously responds to metabolic fluctuations, which is regulated by the cyclic AMP (cAMP) and cAMP receptor protein (CRP) system. The study uses single-cell microscopy, genetic constructs, and mathematical modeling to show how fluctuations circulate through the metabolic and genetic network at sub-cell-cycle timescales. The findings suggest that the cAMP-CRP system may have evolved to control both internal metabolic fluctuations and external growth conditions.

Summary: This study used solution-state NMR spectroscopy to measure transverse proton relaxation rates for methyl groups in folded ribosome-nascent chain complexes, revealing interactions between the nascent chain and ribosome surface driven predominantly by electrostatics. By observing changes in these interactions as subsequent domain emerges, the impact on free energy landscapes associated with co-translational folding process can be deduced.

Summary: Single-cell RNA sequencing (scRNA-seq) technology is a powerful tool for investigating cellular components and interactions in the tumor microenvironment. It has also been used to study the association between tumor microenvironmental patterns and clinical outcomes, and to analyze the effects of drug treatment on specific cell populations. Recent advances in scRNA-seq have led to the discovery of biomarkers and therapeutic targets. The scDrug bioinformatics workflow provides a one-step pipeline for scRNA-seq data analysis and drug prediction, facilitating the exploration of scRNA-seq data and drug repurposing.

Summary: Circular permutation (CP) is a protein sequence rearrangement that creates different positions for the termini of a protein along an imaginary circularized sequence. CP detection algorithms mainly rely on structural information, which limits their application to proteins with known structures. The development of a sequence-based CP search method is essential for identifying more CP pairs and advancing protein research.

Summary: This study reveals that cancer cells express higher levels of eATP synthase under starvation stress, leading to increased production of EVs. The eATP synthase generates extracellular ATP to stimulate EV secretion by enhancing P2X(7) receptor-triggered Ca2+ influx. Surprisingly, eATP synthase is also found on the surface of tumor-secreted EVs. The eATP synthase-coated EVs increase uptake by immune cells and inhibit their proliferation and cytokine release.

Summary: The ectopic ATP synthase complex, which is located on the surface of cancer cells, plays a role in generating ATP in the extracellular environment and has potential as a target for cancer therapy. Through various proteomics and transcriptomics analyses, researchers have discovered that the ATP synthase complex is first assembled in mitochondria and then transported to the cell surface via microtubules and dynamin-related protein 1 (DRP1) and kinesin family member 5B (KIF5B) interactions. The fusion of mitochondrial membrane to the plasma membrane anchors the ATP synthase on the cell surface, as demonstrated by super-resolution imaging and real-time fusion assays in live cells. These findings provide insight into the trafficking of ectopic ATP synthase and contribute to our understanding of tumor progression dynamics.

Summary: This study reexamines the motion of a point charge emitting radiation in an electromagnetic field from the perspective of non-Markovian dynamics. By casting the problem as the non-Markovian dynamics of a Brownian oscillator in a supra-Ohmic environment, it is found that there is no need for a second derivative initial condition and no preacceleration.
