Cytogenetic analysis of a primary adrenocortical carcinoma revealed clonal rearrangements of several autosomes and sex chromosomes. In all metaphases the following marker chromosomes were present: 4p+,t(3;12)(p14;p13),14q+, t(15;20)(p11;q11), t(5;18) (p13.3;p11.2), psu dic(18)t(18.3)(p11.39;p12), and psu dic(20)t(20;9)(q11.2;p11). The results are discussed in relation to the cytogenetic findings in other solid tumors, especially of the kidney.

Chromosomal rearrangements (CR) initiate leukemogenesis in approximately 50 % of acute myeloid leukemia (AML) patients; however, limited targeted therapies exist due to a lack of accurate molecular and genetic biomarkers of refractory mechanisms during treatment. Here, we investigated the pathological landscape of treatment resistance and relapse in 16 CR-AML patients by monitoring cytogenetic, RNAseq, and genome-wide changes among newly diagnosed, refractory, and relapsed AML. First, in FISH-diagnosed KMT2A (MLL gene, 11q23)/AFDN (AF6, 6q27)-rearrangement, RNA-sequencing identified an unknown CCDC32 (15q15.

Acute myeloid leukemia (AML) with a normal karyotype (CN-AML) constitutes approximately 50% of all AML cases, presenting significant prognostic variability, and highlighting the urgent need for the identification of novel molecular biomarkers. In this study, we systematically assessed GPR183 expression levels using qRT-PCR in our clinical follow-up study which included 283 CN-AML patients. Using Kaplan-Meier analysis, we found that patients with high GPR183 expression levels exhibited significantly worse overall survival (OS) (P = 0.

Background: Molecular-clinical prognostic models for Myelodysplastic syndromes (MDS) offer more accurate prognosis predictions, yet existing models often overlook the heterogeneity of mutational profiles against the cytogenetic background. Moreover, how to apply these models in regions where large panel NGS is unaffordable remains a significant challenge to be addressed.
Methods: A total of 237 NK MDS patients from our center were used as the training set to screen for key variables and develop a prognostic model with overall survival (OS) as the endpoint.

Danio rerio, commonly known as zebrafish, is an established model organism for the developmental and cell biology studies. Although significant progress has been made in the analysis of the D. rerio genome, cytogenetic studies face challenges due to the unclear identification of chromosomes.

Quantitative genomic mapping of DNA damage may provide insights into the underlying mechanisms of damage and repair. Sequencing based approaches are bound to the limitations of PCR amplification bias and read length which hamper both the accurate quantitation of damage events and the ability to map them to structurally complex genomic regions. Optical Genome mapping in arrays of parallel nanochannels allows physical extension and genetic profiling of millions of long genomic DNA fragments, and has matured to clinical utility for characterization of complex structural aberrations in cancer genomes.
