We provide evidence that human SLFN5, an interferon (IFN)-inducible member of the Schlafen (SLFN) family of proteins, exhibits key roles in controlling motility and invasiveness of renal cell carcinoma (RCC) cells. Our studies define the mechanism by which this occurs, demonstrating that SLFN5 negatively controls expression of the matrix metalloproteinase 1 gene (MMP-1), MMP-13, and several other genes involved in the control of malignant cell motility. Importantly, our data establish that SLFN5 expression correlates with a better overall survival in a large cohort of patients with RCC. The inverse relationship between SLFN5 expression and RCC aggressiveness raises the possibility of developing unique therapeutic approaches in the treatment of RCC, by modulating SLFN5 expression.

Diabetic ulcers (DUs) present significant physical and psychological challenges to patients, while placing a significant economic burden on healthcare systems. Promoting the blood vessel regeneration is critical for ensuring the delivery of essential nutrients and oxygen to the injured area, thereby supporting the healing process. To gain insight into the complex molecular mechanisms that drive DUs healing, we performed a comprehensive analysis of single-cell transcriptomic data from healing and non-healing DU states.

Lactylation, a newly identified post-translational modification, is uncertain in its implication in triple-negative breast cancer (TNBC). In this study, we analyzed 60 TNBC samples using immunohistochemical staining and revealed elevated levels of pan-lactylated proteins and specific histone H4K12 lactylation in tumor tissues, correlating with TNBC progression. Lactate exposure in TNBC cell lines significantly induced lysine lactylation at the H4K12 site, leading to alterations in gene profiles and reduced apoptosis.

Observational studies indicate that variations in peripheral blood mononuclear cell (PBMC) subsets are associated with an increased risk of pulmonary tuberculosis (PTB) and coronavirus disease 2019 (COVID-19), but causal validation is lacking. Here, we combined single-cell expression quantitative trait locus (sc-eQTL) and two-sample mendelian randomization (MR) analyses to elucidate the causal relationship between PBMC subsets and the occurrence of PTB and COVID-19 and verified by RT-qPCR. We observed an increase in the CD4 Effective Memory T Cell (CD4 T) cluster in both PTB and COVID-19 patients according to the single-cell transcriptional landscape of PBMC.

Recent advancements have elucidated the multifaceted roles of the Schlafen (SLFN) family, including SLFN5, SLFN11, SLFN12, SLFN13, and SLFN14, which are implicated in immunological responses. However, little is known about the roles of this gene family in relation to malignancy development. The current study aimed to explore the diagnostic and prognostic potential of Schlafen family genes in colorectal adenocarcinoma (COAD) through bioinformatics analysis.
