Summary: This article presents an online tool called IthaCNVs, which aids in the diagnosis of haemoglobinopathies associated with copy number variants (CNVs). The tool allows filtering of entries based on breakpoint information, chromosomal and locus positions, MLPA probes, and affected genes, assisting laboratory staff and clinicians in confirming the diagnosis of CNVs.

Summary: Chromosomal instability (CIN) is a fundamental property of cancer and a key mechanism of tumorigenesis and progression. It is found in various cancers and is associated with poor clinical outcomes. However, there have been relatively few studies on this process, mainly due to the difficulty of measuring it clinically.

Summary: Cytogenetic and molecular assessments play crucial roles in the diagnosis and treatment of cancer. Laboratory approaches like multiplex ligation-dependent probe amplification and droplet digital PCR are exceptional tools for detecting genetic alterations accurately and sensitively in molecular oncology. Personalized medicine relies on the correct and reliable molecular characterization of diseases, influencing therapeutic choices.

Summary: This article presents a case of vertebral metastasis in a patient with glioblastoma. The study found that younger age at initial presentation, multiple surgical interventions, and long overall survival seem to be risk factors for vertebral metastasis. As the prognosis of glioblastoma improves over time, vertebral metastasis appears to be more common, therefore extradural metastasis should be considered in the treatment of glioblastoma. Further genomic analysis on multiple paired specimens is necessary to elucidate the molecular mechanisms of vertebral metastasis.

Summary: The study clarified the prevalence of RET gene CNVs in sporadic MTC cases and their potential role in MTC development. Results showed that RET gene CNVs are rare events in sporadic MTC and are associated with RET somatic mutation, suggesting that they may not be a primary driver mechanism of tumoral transformation.

Summary: In this study, genetic alterations in a large cohort of gastric-type cervical adenocarcinomas (GCA) and other related adenocarcinomas were analyzed and compared. It was found that GCAs commonly harbor mutations in TP53, CDKN2A, KRAS, and STK11, and exhibit low levels of copy number alterations. GCAs show distinctive genetic mutation characteristics compared to other adenocarcinomas, with higher mutation frequencies in certain genes.

Summary: Gastric cancer is the third leading cause of cancer death globally. This study revealed that KLF5 amplification and over-expression in gastric cancer may support cell proliferation, suggesting an oncogene-like role for KLF5 in gastric cancer. The findings also showed a correlation between higher KLF5 expression and more locally invasive gastric cancer with higher T stage.

Summary: In fungi, homologous recombination and RNA silencing mechanisms cooperatively regulate the de novo DNA methylation of transposable elements such as MAGGY, with RecA domain-containing proteins and uncharacterized Ddnm1 protein forming complexes to mediate the process. Mutants of specific RNA silencing components in Pyricularia oryzae show impaired copy number-dependence of MAGGY methylation, suggesting a physical interaction between RNA silencing machinery and homologous recombination components.

Summary: Ploidy changes are common in nature and have significant impacts on evolution, functional specialization, and tumorigenesis. This study reveals that gene expression scales allometrically with cellular ploidy, and the scaling is achieved through decreased rRNA and ribosomal protein abundance and reduced translation. The reduced activity of Tor1 with increasing ploidy leads to diminished rRNA gene repression, which is regulated by the Tor1-Sch9-Tup1 signaling pathway. The mTORC1-Sch9/S6K-Tup1/TLE1 pathway plays a crucial role in proteome remodeling in response to increased ploidy.

Summary: A study on genomic plasticity in liver metastatic samples of colorectal cancer revealed an increased frequency of specific CN in metastatic lesions after first-line treatment. Comparison of CNA profiles in lesions with different treatment responses showed focal genomic divergences in post-treatment resistant lesions but not in responder lesions. Examining metastatic lesions is crucial as 15 out of 18 independently validated CNA regions associated with progression-free survival were only identified in metastatic lesions, not in primary tumors.

Summary: Copy number variation (CNV) is a common polymorphism in the human genome, with somatic alterations at CNV sites detected in 39.9% of the CNV probes examined in invasive breast cancers. The most frequently altered regions included gains of 1q21-22, 8q21-24, 1q44, 3q11, and losses of 16q22-24. Gene ontology analysis revealed correlations between CNAs and transcription/RNA metabolism in relation to HER2 positivity and menopausal status in breast cancer patients.

Summary: Studying neoplasia in Drosophila has provided insights into the impact of spontaneous mutations on early cancer development. Using whole-genome sequencing data from neoplasia in the fly intestine, key gene abnormalities driving tumor formation were identified. The genomic mutational burden in fly neoplasia was found to be similar to several human cancers, shedding light on mutational dynamics over a short timescale.

Summary: YAP1 is highly upregulated in peritoneal carcinomatosis tumor cells, contributing to cancer stem cell properties and metastasis. Inhibition of YAP1 can significantly slow tumor growth and eliminate peritoneal carcinomatosis in preclinical models. Pharmacological inhibition of YAP1 can reduce cancer stem cell-like properties and suppress tumor growth, especially in combination with cytotoxic drugs in vivo models.

Summary: High expression of LIPC is associated with poor clinical outcomes and plays an important role in regulating cell migration and invasion in Borrmann type 4 gastric cancer. High LIPC expression correlates with lymph node metastasis, advanced TNM stage, and poor overall survival in Borrmann type 4 gastric cancer patients. By reducing LIPC expression, cell invasion and migration are suppressed and specific gene expression is altered in Borrmann type 4 gastric cancer.

Summary: The study compared different staging systems for predicting the prognosis of gastric cancer patients, finding that the LODDS staging system was superior to other lymph-node classifications. For predicting the prognosis of GC patients, the modified TLM staging system showed better discriminative ability and optimistic prognostic stratification compared to the 8th TNM or TRM staging systems.

Summary: Our study found that platelet to lymphocyte ratio (PLR) is an effective marker to predict the effects of chemotherapy in patients with stage II colorectal cancer. In the low-PLR subgroup, chemotherapy did not significantly improve overall survival compared to non-chemotherapy patients, while in the high-PLR subgroup, chemotherapy patients had a significantly longer overall survival.

Summary: The study found that patients with rectal cancer achieving pathologic complete response (pCR) had significantly higher 10-year overall survival and 5-year disease-free survival compared to those in the non-pCR group. Improvement in tumor regression after neoadjuvant therapy was associated with increased overall survival and disease-free survival, and the pCR group had longer overall survival and disease-free survival than the non-pCR group. The results suggest a positive relationship between better tumor regressions and improved survival benefits, highlighting the importance of achieving pCR in the treatment of rectal cancer.
