Recent research has linked lethal (3) malignant brain tumor-like 3 (L3MBTL3) to cancer aggressiveness and a dismal prognosis, but its function in gastric cancer (GC) is unclear. This research investigated the association between L3MBTL3 expression and clinicopathological characteristics of GC cases, as well as its prognostic value and biological function based on large-scale databases and clinical samples. The results showed that L3MBTL3 expression was upregulated in malignant GC tissues, which was associated with a shortened survival time and poor clinicopathological characteristics, including TNM staging. A functional enrichment analysis including GO/KEGG and GSEA illustrated the enrichment of different L3MBTL3-associated pathways involved in carcinogenesis and immune response. In addition, the correlations between L3MBTL3 and tumor-infiltrating immune cells were determined based on the TIMER database; the results showed that L3MBTL3 was associated with the immune infiltration of macrophages and their polarization from M1 to M2. Furthermore, our findings suggested a possible function for L3MBTL3 in the regulation of the tumor immune microenvironment of GC. In summary, L3MBTL3 has diagnostic potential, and it also offers new insights into the development of aggressiveness and prognosis in GC.

L3MBTL3 and STAT3 collaboratively upregulate SNAIL expression to promote metastasis in female breast cancer.

The STAT3 pathway promotes epithelial-mesenchymal transition, migration, invasion and metastasis in cancer. STAT3 upregulates the transcription of the key epithelial-mesenchymal transition transcription factor SNAIL in a DNA binding-independent manner. However, the mechanism by which STAT3 is recruited to the SNAIL promoter to upregulate its expression is still elusive.

Urolithiasis, a common urological disorder affecting about 10% of the global population, is known for its high recurrence rate, yet its genetic mechanisms remain poorly understood. This study aimed to fill this gap by identifying potential pathogenic genes associated with urolithiasis using a multi-omics Mendelian randomization approach. We conducted a comprehensive analysis that integrated genome-wide association studies (GWAS), expression quantitative trait loci (eQTL), methylation quantitative trait loci (mQTL), and protein quantitative trait loci (pQTL) data.

Background: Breast cancer, which is the most prevalent form of cancer among women globally, encompasses various subtypes that demand distinct treatment approaches. The tumor microenvironment and immune response are of crucial significance in the development and progression of breast cancer. Nevertheless, there has been scant evidence concerning the genes within breast cancer - specific immune cells.

Article Synopsis
- Individuals with lower education levels are more likely to experience diabetic kidney disease (DKD) and chronic kidney disease (CKD), and this study aims to analyze how cardiometabolic traits mediate the relationship between education and these conditions.
- The study utilized various genetic analysis methods to evaluate the causal effects of education on DKD and CKD, and identified several cardiometabolic traits that mediate these relationships, particularly emphasizing the role of Body Mass Index (BMI).
- Findings showed that increased education is linked to a significant decrease in the risks of DKD (48.64%) and CKD (29.08%), highlighting the importance of addressing educational disparities to improve kidney health outcomes.
Lysine Methylation-Dependent Proteolysis by the Malignant Brain Tumor (MBT) Domain Proteins.

Lysine methylation is a major post-translational protein modification that occurs in both histones and non-histone proteins. Emerging studies show that the methylated lysine residues in non-histone proteins provide a proteolytic signal for ubiquitin-dependent proteolysis. The SET7 (SETD7) methyltransferase specifically transfers a methyl group from S-Adenosyl methionine to a specific lysine residue located in a methylation degron motif of a protein substrate to mark the methylated protein for ubiquitin-dependent proteolysis.
