Introduction: Acute myeloid leukemia with normal cytogenetics (CN-AML) represents a heterogeneous group having diverse genetic mutations. Understanding the significance of each of these mutations is necessary. In this study, we evaluated the prognostic role of MN1 expression in adult CN-AML patients.
Method: One hundred and sixty-three de-novo adult AML patients were evaluated for MN1 expression by real-time PCR. MN1 expression was correlated with the clinical characteristics of the patients and their outcomes.
Results: Higher MN1 expression was associated with NPM1 wild-type (p<0.0001), CD34 positivity (p=0.006), and lower clinical remission rate (p=0.027). FLT3-ITD and CEBPA mutations had no association with MN1 expression. On survival analysis, a high MN1 expression was associated with poor event-free survival (Hazard Ratio 2.47, 95% Confidence Interval: 1.42-4.3; p<0.0001) and overall survival (Hazard Ratio 4.18, 95% Confidence Interval: 2.17-8.08; p<0.0001). On multivariate analysis, the MN1 copy number emerged as an independent predictor of EFS (p<0.0001) and OS (p<0.0001).
Conclusion: MN1 expression is an independent predictor of outcome in CN-AML.

Relapsed pediatric B-cell acute lymphoblastic leukemia (B-ALL) remains one of the leading causes of cancer mortality in children. We performed Hi-C, ATAC-seq, and RNA-seq on 12 matched diagnosis/relapse pediatric leukemia specimens to uncover dynamic structural variants (SVs) and 3D chromatin rewiring that may contribute to relapse. While translocations are assumed to occur early in leukemogenesis and be maintained throughout progression, we discovered novel, dynamic translocations and confirmed several fusion transcripts, suggesting functional and therapeutic relevance.

As one of a traditional Chinese medicine with dual applications in both medicinal treatment and dietary consumption, the mature seeds of D. lablab were reported to be rich in saponins and have a good effect on inflammatory related diseases. However, the substance basis for its anti-inflammatory activity remains unclear.

We developed a 3D glomeruli tissue chip for glomerulonephritis (GN) testing, featuring a gravity-driven glomerular filtration barrier (GFB) with human podocytes and endothelial cells with a bidirectional flow in the bottom channel. Using puromycin-induced GN, we observed decreased cell viability, increased albumin permeability, and reduced WT1 and nephrin compared to the normal GFB. Tacrolimus restored cell viability, reduced albumin permeability, and increased WT1 expression.

Article Synopsis
- Chicken breeders are focusing on intensive genetic selection to enhance growth rates, leading to new breeds with increased fat accumulation.
- A study utilized RNA-seq to analyze fat tissue at various growth stages to understand how genetics influence fat development in broilers.
- Key findings indicated critical periods for fat growth and identified several candidate genes that could be important for future breeding and research on chicken adipose tissue development.
