Summary: Recent advances in computational power and algorithms have extended the time scales of molecular dynamics (MD) simulations. However, MD simulations still face limitations in observing conformational transitions associated with biomolecular processes. To address this challenge, enhanced sampling techniques such as the weighted ensemble (WE) method have been developed to estimate kinetic rate constants by sampling transitions between metastable states using weighted trajectories. In this study, deep-learned kinetic modeling approaches are introduced to extract statistically relevant information from short MD trajectories and provide a well-sampled initial state distribution for WE simulations. This hybrid approach overcomes statistical bias and produces a refined free energy landscape closer to the steady state, enabling efficient sampling of kinetic properties.

Summary: Automatic tracking of multiple animals is important for studying behaviors, but it is challenging due to issues like discontinuities in animal motion. The software toolkit Argos addresses these challenges by providing tools for compressing videos, generating training sets for a neural network, tracking animals in videos, and facilitating manual review and correction of tracks. Argos can help reduce the data storage and analysis workload, speed up the analysis process, and enable tracking of markerless animals in complex environments for extended periods.

Summary: Conventionally, web portal reliability is validated using conventional methods, but these methods are not effective. This paper proposes the inclusion of quality factors like usability in addition to conventional testing to improve reliability. Testing profiles, including software operational profile, input space profile, and usability profile, are employed to measure reliability. The proposed scheme is compared with the conventional method and the results show its effectiveness, providing recommendations for testing and measuring reliability in web-based software or applications.

Summary: Mass spectrometry imaging (MSI) techniques provide high sensitivity and selectivity in revealing the spatial distributions of molecules on a surface. However, processing the large volumes of data generated by MSI into useful ion images can be challenging. In addition, the data handling strategies for continuous ionization sources differ from those used for pulsed ionization sources. Currently, there is a lack of data-handling software specifically designed for MSI data generated with continuous ionization sources and automatic gain control (AGC).

Summary: Combination of ribonucleases (RNases) is commonly used to digest RNA into oligoribonucleotide fragments for liquid chromatography-mass spectrometry (LC-MS) analysis. Cusativin and MC1, nucleotide-specific endoribonucleases, are ideal tools for RNA modification mapping due to their high specificity for cytidine and uridine. New efficient and time-saving protocols have been developed to enhance the expression and purification of these RNases, resulting in highly active recombinant enzymes.

Summary: Short open reading frames (sORFs) have the potential to encode proteins, leading to a new research focus in proteomics. Mass spectrometry (MS) is a significant tool for directly detecting the sequence of sORF encoded peptides (SEPs), but the low abundance and short sequences of SEPs present challenges in detection.

Summary: This study reveals a quality control mechanism for nuclear retention and degradation of misprocessed mRNA. The researchers find that specific sequences associated with misprocessed mRNA require zinc finger protein ZFC3H1 and a component of spliceosomal U1 snRNP, U1-70K, for nuclear retention. They also demonstrate that disassembling nuclear speckles impairs the nuclear retention of these RNAs.

Summary: As a vital life form in the biosphere, cyanobacteria have been the subject of significant research growth. Protein-protein interactions (PPIs) play a crucial role in biological functions, regulating proteins and forming functional complexes. However, PPI studies in cyanobacteria lag behind those in mammals and lack integration. To address this, we developed CyanoMapDB, a database that provides experimental evidence of cyanobacterial PPIs. It includes 52,304 PPIs among 6,789 proteins from 23 cyanobacterial species, collected from UniProt, STRING, IntAct, and co-fractionation MS data. CyanoMapDB allows users to easily query proteins, explore interacting proteins from various sources, and visualize protein networks. It is expected to advance research in cyanobacteria and plants.

Summary: The incidence rate of atrial fibrillation (AF) has remained high in recent years, and the molecular mechanism of disease development remains unclear. Microproteins, which are ribosomally translated gene products, have been found to play important biological roles but have received little attention in AF research. In this study, we analyzed the microproteomic profiles of 65 AF patients and 65 healthy subjects. We identified 4 microproteins that were significantly different, including 3 annotated ones and 1 novel one. By using machine learning methods, we developed a diagnostic model with microproteins that had comparable and excellent performance to a model with global proteins. Our findings confirm the abnormal expression of microproteins in AF and provide new insights into the mechanism study of AF.

Summary: Short open reading frame-encoded peptides (SEPs), ranging from 2 to 100 amino acids, play important roles in various biological processes. In this study, we analyzed SEPs in five different brain regions of mice using mass spectrometry-based proteomics. We identified 373 SEPs, with approximately 83% of them being novel. Half of the identified SEPs were encoded by non-coding RNA, and about one-third showed orthology across species. Each brain region had specific SEPs, such as IP_1018875 in the frontal cortex, which may be related to autophagy and neuronal signaling. These findings expand our understanding of the mouse brain proteome and provide valuable insights for future studies on the function of SEPs.
