Introduction

Plays a crucial role in the regulation of macrophage activation in response to viral or bacterial infections within the respiratory tract. Mechanistically, TRIM29 interacts with IKBKG/NEMO in the lysosome where it induces its 'Lys-48' ubiquitination and subsequent degradation. In turn, the expression of type I interferons and the production of pro-inflammatory cytokines are inhibited. Additionally, induces the 'Lys-48' ubiquitination of STING1 in a similar way, leading to its degradation.

ABSTRACTSarcoids are the most frequently diagnosed dermatological tumour in horses. It is a disease that can affect various species of equids, such as donkeys, mules and zebras. This type of tumour can develop in all horse breeds, regardless of age and gender. Treatment options depend on many factors, such as the type of lesion, location, extent, owner preference and financial considerations. In the present study, we investigated the TRIM29 expression, the methylation status of its first exon and its involvement in the formation of equine sarcoids. Bisulfite sequencing PCR (BSP) was used to determine DNA methylation at CpG sites and real‐time quantitative polymerase chain reaction (qPCR) was used to detect TRIM29 expression level. Our results showed that TRIM29 is significantly downregulated in lesional samples (FC = −3.72; p < 0.001). Furthermore, TRIM29 expression was significantly correlated (R = −0.73; p < 0.001) with hypermethylation of its specific CpG sites in the first exon of this gene. Our research has demonstrated that the identification of increased methylation of CpG sequences in horse sarcoids, along with the decreased expression of the TRIM29 gene, is an important step towards understanding the molecular mechanisms underlying the disease. These findings can serve in the future as a diagnostic biomarker for horse sarcoids and help in detecting the disease.

Background:Oral squamous cell carcinoma (OSCC) is an aggressive oral malignancy. Metastasis and postoperative recurrence are major causes of a high mortality of OSCC. The landscape of immune cells in OSCC remained to be comprehensively explored.Methods:Tumor tissues of OSCC patients were collected from the Gene Expression Omnibus database, based on which single-cell sequencing analysis was performed to identify subtypes of macrophages and to annotate the subpopulations according to the expression levels of cell marker genes. Functional enrichment analysis was performed to explore the biological processes involved in each cell subcluster. Gene regulatory networks driven by SPECIFIC transcription factors (TFs) were developed applying single-cell regulatory network inference and clustering (SCENIC) analysis. Binding strength between receptors and ligands between different cells was analyzed using cell communication analysis.Results:A single-cell landscape in OSCC was successfully developed and a total of 11 cell clusters were identified. Specifically, CD163 + macrophages were a crucial type of macrophage with 4 cell subpopulations, namely, SAT1 + macrophages, IDO1 + macrophages, TRIM29 + macrophages, and CMKLR1 + macrophages. IDO1 + macrophages and CMKLR1 + macrophages mainly had the characteristics of M1-type macrophages. CMKLR1 + macrophages fulfilled the function of M1-type macrophages to inhibit OSCC progression. IDO1 + macrophages and CMKLR1 + macrophages were both involved in the activation response of T cells. CMLKR1 + macrophages had a stronger activating effect on T cells. CMKLR1 + macrophages directly regulated the proliferation of epithelial cells and inhibited the progression of OSCC.Conclusion:CMKLR1 + macrophages in OSCC were identified as a crucial cell subpopulation of macrophages in inhibiting tumor progression. Adjusting the infiltration abundance and cell activity of CMKLR1 + macrophages may be a novel therapeutic direction to improve OSCC prognosis.

PURPOSEGlucose not only provides energy for tumor cells, but also provides various biomolecules that are essential for their survival, proliferation and invasion. Therefore, it is of great clinical significance to understand the mechanism of how tumor cells adapt to metabolic stress and maintain their survival. The aim of this research was to study the critical role of OGT and TRIM29 O-GlcNAc modification driven adaptability of PDAC cells to low glucose stress, which might have important medical implications for PDAC therapy.METHODSWestern blotting, mass spectrometry and WGA-immunoprecipitation were used to examined the levels of OGT and O-GlcNAc glycosylated proteins in BxPC3 and SW1990 cells in normal culture and under glucose deprivation conditions. Crystal violet assay, flow cytometry, RIP, RT-qPCR, protein stability assay, biotin pull down were used to investigate the mechanism of OGT and TRIM29-mediated adaptive response to glucose deficiency in PDAC cells.RESULTSThe current study found that under the condition of low glucose culture, the levels of OGT and O-GlcNAc glycosylation in PDAC cells were significantly higher than those in normal culture. Moreover, the high expression of OGT has a protective effect on PDAC cells under low glucose stress. This study confirmed that there was no significant change in mRNA level and protein degradation of OGT under low glucose stress, which was mainly reflected in the increase of protein synthesis. In addition, O-GlcNAc modification at T120 site plays a critical role in the metabolic adaptive responses mediated by TRIM29.CONCLUSIONSTaken together, our study indicated that O-GlcNAcylation of TRIM29 at T120 site and OGT translation forms a loop feedback to facilitate survival of PDAC under glucose deficiency.
