Summary: Cellular effects of hypergravity, particularly its impact on gene expression in Jurkat T cells, were investigated in this study. The researchers observed a biphasic time course of gene expression response, with a transition point occurring at approximately 7 minutes. Upregulated genes shifted towards the center of the nuclei, while downregulated genes shifted towards the periphery. Interestingly, the gene expression pattern in response to hypergravity was distinct from that of other stress factors such as oxidative stress, heat shock, or inflammation. The researchers also highlighted the significant impact of routine centrifugation on the transcriptome of cells, recommending caution when using this method for RNA analysis.

Summary: Epidemiological evidence suggests that low levels of SELENOF expression are associated with late-stage breast tumors and predict poor patient outcome. Manipulating SELENOF expression in breast cancer cells can affect cell viability and reduce aggressive cancer phenotypes, enhancing response to breast cancer therapy.

Summary: This study documents a highly optimized synthesis method for the Sec-to-Cys homologue of human selenoprotein F, and elucidates the disulfide pairing mode of SelF. The research not only lays the foundation for the synthesis of natural selenoproteins, but also provides important insights into the structure of the SelF domain.

Summary: This study successfully expressed the mature form of human GPx3 and found that mutations can affect its secondary structure and tetramer formation, thereby influencing its catalytic activity. This provides an important foundation for further studies on the catalytic mechanism and function of hGPx3.

Summary: Ribosomes perform complex tasks in protein synthesis, requiring long-range communication between functional centers. Experimental studies suggest that certain ribosomal proteins are essential for remote communication, and may form networks to optimize connectivity between these centers. The evolutionary, structural, and mathematical analysis shows that ribosomal protein networks converge towards non-random graphs, indicating coevolution for efficient communication pathways. Additionally, the acquisition of aromatic residues in newly connected eukaryotic ribosomal proteins suggests strong selective pressure for the formation of allosteric pathways.

Summary: Ubiquitination and deubiquitination cycle of ribosomal proteins play a crucial role in efficient protein translation. Ubiquitination at lysine 83 of eS7 is important for translation efficiency, with Otu2 and Ubp3 identified as the deubiquitinating enzymes. Ubp3 inhibits polyubiquitination to maintain eS7 in a mono-ubiquitinated form, while Otu2 promotes mRNA dissociation from 40S ribosomes in the recycling step.

Summary: This study developed controlled-release systems for micronutrients using soy protein as raw material. The results showed the great potential of these systems, especially when combined with nanotechnology, to incorporate micronutrients into crops and improve the benefits of conventional fertilization.

Summary: Moonlighting proteins refer to proteins capable of performing multiple functions within the same polypeptide chain. They have potential applications in various fields, including health, pharmacology, and nutrition. Some ribosomal proteins involved in protein assembly and translation also exhibit antimicrobial activity and may have potential as alternatives to antibiotics. However, the mechanism of action of ribosomal proteins as antimicrobial peptides is not completely understood.

Summary: It has been 50 years since the discovery of the first selenoprotein, and our understanding of the importance of selenium has greatly increased. We now know that the brain relies on selenium for proper functioning, and a lack of certain selenoproteins can lead to neurodegeneration. Additionally, selenoprotein-mediated redox balance has been found to affect neuronal activity.

Summary: Fish is important for a healthy diet due to its content of long chain omega-3 fatty acids, but other nutrients and proteins may also play a role in its beneficial health effects. A study found that both salmon fishmeal and whey protein intake reduced glucose and triglyceride levels in the blood, and increased the concentration of 22 amino acids and derivatives. The study also showed that there were no significant differences in gene regulation between cells cultivated in fasting serum and postprandial serum after consuming fishmeal or whey.

Summary: This study assessed the association between immune cell infiltration and colorectal cancer relapse risk, finding that CD4+ memory activated T cell infiltration was linked to longer time to disease relapse. Through meta-analysis, 10 immune cell types were identified to be associated with disease relapse, showing that immune cell type infiltration is a better predictor of CRC relapse than other biomarkers.
