Summary: The researchers developed a control-free method called HiSV for identifying large-scale structural variations from Hi-C samples. HiSV achieved superior accuracy and sensitivity through evaluations on simulated data sets and cancer cell lines, and effectively captured complex SVs. HiSV can also supplement the results of WGS methods.

Summary: This study uses multi-omics analysis to investigate heterogeneity and evolution in oesophageal squamous cell carcinoma (ESCC). The study reveals ongoing chromosomal instability underlying genomic, epigenomic, and transcriptomic heterogeneity. It also shows that immune infiltration acts as a selective force in shaping the clonal evolution of ESCC.

Summary: This study investigates the regulatory effect of non-coding large-scale structural variations (SVs) on proto-oncogene activation by profiling 3D cancer genome maps. The analysis reveals the establishment of de novo chromatin contacts that span multiple topologically associating domains (TADs) and the occurrence of super-enhancer (SE) hijacking and its clonal characteristics. The activation of oncogenes and increased drug resistance due to SE hijacking are validated using CRISPR-Cas9. This research provides insights into the regulatory principles of large-scale SVs in oncogene activation and their clinical implications.

Summary: A study sequencing 52 tumor samples from 33 ESCC patients who received radiotherapy combined with 5-fluorouracil/platinum revealed the impact of chemoradiotherapy on clonal evolution, with MYC gain potentially serving as a marker for therapy resistance. The findings enhance understanding of therapeutic resistance and support the rationale for precision chemoradiotherapy.

Summary: Structural variants (SVs) contribute to sequence variability in genomes and are significant in human genomics and precision medicine. However, due to the complexities of the human genome, SV discovery in individuals has been challenging. The introduction of low-error long-read sequencing technologies, such as PacBio HiFi, may provide a solution to these challenges.

Summary: This study used cfDNA to investigate the CNV in BCL9 and RPS6KB1 genes and its impact on prognosis in HCC. The results showed that gain in CNV of BCL9 and RPS6KB1 genes was detected in 14% and 24% of HCC patients, respectively. CNV gain in these genes was associated with different risk factors and showed higher mortality rates and reduced survival times.

Summary: Background analysis of circulating tumor DNA is crucial for cancer care, but previous studies focused on short DNA fragments. Bisulfite sequencing, a traditional method for methylation analysis, causes DNA degradation. This study overcame these limitations using single-molecule sequencing and discovered a previously unknown long cfDNA population.

Summary: CTCs have been found to be associated with metastasis and survival in breast cancer patients. Evaluating the expression of estrogen receptors (ER) in CTCs may help with personalized treatment. Some patients have both ER-positive and ER-negative CTCs at the time of metastasis, which may lead to resistance to hormonal therapy. Therefore, monitoring the status of CTC-ER in breast cancer patients can provide prognostic and predictive value.

Summary: Fc gamma receptors (FcγR) are cell-surface glycoproteins that play a role in immune responses. The CNR5 deletion on the FCGR locus can lead to loss and recombination of FCGR genes, potentially affecting immune function. The distribution of FCGR polymorphism shows significant variation in the highlands of Ecuador, with CNR5 deletion being relatively common.

Summary: This study analyzed patients from two distinct families with a novel distal titinopathy phenotype associated with the same CNV in the TTN gene. The CNV reported in this study is the most proximal out-of-frame TTN variant and leads to aberrant splicing transcripts, resulting in frameshift and possibly dominant effects. This data represents a novel phenotype-genotype association and provides hypotheses for its dominant effects.

Summary: The study found that subgenomic RNA transcripts (particularly sgN) can serve as markers of active SARS-CoV-2 virus replication and are correlated with high viral loads. The loss of sgN indicates the negativization of patient condition. A new detection kit has been developed to detect sgN, gene E, gene ORF1ab, and gene RNAse P. In addition, in vitro experiments showed that 2'-O-methyl antisense RNA related to the sgN sequence can inhibit SARS-CoV-2 N protein synthesis, viral replication, and syncytia formation in human cells, suggesting potential therapeutic applications against SARS-CoV-2.

Summary: Cardiomyopathy greatly affects the well-being and survival of patients with 13-thalassemia or transfusion-dependent myelodysplastic syndromes. Recent research has found a connection between Nrf2 activity and iron metabolism. In this study, Nrf2-/- mice developed age-dependent cardiomyopathy characterized by oxidation, degradation of SERCA2A, and iron accumulation. The absence of Nrf2 paradoxically protected against heart iron accumulation when exposed to an iron overload diet. The activation of the unfolded protein response system and cardiac fibrosis were observed in a model of 13-thalassemia independent of heart iron content. These findings provide insights into potential early treatment for cardiomyopathy in patients with 13-thalassemia.

Summary: Cornelia de Lange Syndrome (CdLS) is a rare genetic disorder that affects multiple organs. This study presents clinical and genetic findings of a patient with CdLS type 4, a syndrome that has been rarely described before. The patient exhibited previously reported clinical features of CdLS type 4 as well as additional symptoms not mentioned previously. The novel genetic variant found in this patient suggests its pathogenicity. This report provides valuable insights for counseling future CdLS type 4 cases.

Summary: Approximately 50% of high-risk neuroblastomas (NB) relapse within two years after treatment, and additional therapeutic options are needed for relapsed or refractory patients. The identification of ALK somatic mutations or amplification is crucial for the treatment of these patients. ALK inhibitors may have a significant role in treating high-risk, ALK-mutated NB patients in the era of precision medicine.

Summary: In this study, we introduce a machine learning-powered tomographic phase imaging flow cytometry system that can provide high-throughput 3D phase-contrast tomograms of individual cells for the identification of circulating tumor cells in microfluidic cytometry condition. We propose a hierarchical machine learning decision-maker that utilizes 3D morphological features calculated from the cells' refractive index to accurately discriminate tumor cells from white blood cells as well as identify the tumor type. Experimental results demonstrate a success rate of over 97% in identifying tumor cells and an accuracy of over 97% in discriminating between different cancer cell types, highlighting the potential of this stain-free liquid biopsy tool for detecting and classifying circulating tumor cells in blood.

Summary: The use of array comparative genomic hybridization (array-CGH) has identified new microdeletion/microduplication syndromes, including the 9q21.13 microdeletion syndrome. This syndrome involves the loss of a specific genomic region and is associated with developmental delay, intellectual disability, autistic behavior, seizures, facial dysmorphism, myopia, and previously unreported brain anomalies. A study of 28 patients, including our case, allowed for the classification and analysis of candidate genes, as well as the correlation between genotype and phenotype. These findings provide a better understanding of the syndromic spectrum of 9q21.13 microdeletion syndrome and suggest the need for regular ophthalmological and neurological monitoring.

Summary: Medulloblastoma (MB) is a childhood tumor of the cerebellum that has been classified into four molecular subgroups and further divided into biologically distinct subtypes. The brain tumor microenvironment (BTME) plays a crucial role in regulating cancer progression in MB by influencing immune cells. Previously, MB was considered to have a low influx of immune cells, but recent studies have shown the presence of immunosuppressive immune cells in the BTME. This article provides an overview of the epigenetic alterations in MB and explores the potential of new immunotherapeutic approaches to target these immunosuppressive cells.
