This study aimed to elucidate the molecular landscape of neuroendocrine-like bladder tumors, focusing on the involvement of β-catenin localization. Analyzing the transcriptome data and benefiting from the molecular classification tool, we undertook an in-depth analysis of muscle-invasive bladder cancers to uncover the molecular characteristics of the neuroendocrine-like differentiation. The study explored the contribution of transcription factors and chromatin remodeling complexes to neuroendocrine differentiation in bladder cancer. The study revealed a significant correlation between β-catenin localization and neuroendocrine differentiation in muscle-invasive bladder tumors, highlighting the molecular complexity of neuroendocrine-like tumors. Enrichment of YY1 transcription factor, E2F family members, and Polycomb repressive complex components in β-catenin-positive tumors suggest their potential contribution to neuroendocrine phenotypes. Our findings contribute valuable insights into the molecular complexity of neuroendocrine-like bladder tumors. By identifying potential therapeutic targets and refining diagnostic strategies, this study advances our understanding of endocrinology in the context of bladder cancer.

The number of individuals who chose to receive the vaccine at their own expense, despite being ineligible for public subsidies due to their age, is unknown and has been nominally considered to be zero. Our aim is to produce a more accurate estimate of this number using recently released proprietary data. First, we estimated the total number of self-funded HPV vaccinations occurring from 2010 to 2012 using public data from the Ministry of Health, Labour and Welfare and our previously reported data on the number of HPV vaccinations eligible for public subsidy. Second, using proprietary data from the vaccine manufacturer, we calculated the distribution of self-funded vaccination shots by age. Finally, we combined these data to estimate the number of self-funded HPV vaccinations by birth fiscal year (FY) relative to a yearly reference population. We found that 78,264 individuals born in FY1993 and 58,190 born in FY1992 self-funded their vaccinations, representing 13.6% and 10.0% of the reference population, respectively. Additionally, we found that 5%–10% of individuals born from FY1986 to FY1991 self-funded their vaccinations.

During that time, lung cancer treatment has undergone a major paradigm shift. Targeted therapy for lung cancer has expanded, and most patients with non-small cell lung cancer (NSCLC) are now being evaluated using genetic analysis with a next-generation sequencing or a multiplex reverse transcriptase polymerase chain reaction assay. Ishida et al. provide an excellent study that explains the utility of comprehensive genomic profiling assays.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; However, the hospital where I work is a community hospital and access to these tests is limited. I was inspired by this study and would like to share two clinical questions regarding current companion diagnostics. And if possible, I would like to hear an experts opinion on genomic medicine.&lt;/p&gt;&lt;p&gt;First, is it possible to measure all genes with only one next-generation sequencing test? In the case of epidermal growth factor receptor (EGFR), discrepancies between next-generation sequencing and PCR have been reported.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; In Sakaguchi et al., EGFR-tyrosine kinase inhibitors were reported to be successful even in cases reported as negative by next-generation sequencing and positive for EGFR by PCR. For the ALK fusion gene, 15.5% of immunohistochemistry-positive patients are negative for next-generation sequencing tests.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; Therefore, the usefulness of immunohistochemistry in detecting ALK-positive patients has also attracted attention. Next-generation sequencing is also useful for measuring the resistance mechanism of EGFR-positive lung cancer,&lt;span&gt;&lt;sup&gt;4, 5&lt;/sup&gt;&lt;/span&gt; and it might be important to use targeted therapy for sequencing in the future. Which test should a patient with lung cancer undergo first at diagnosis? Should each of these tests be performed separately or simultaneously? Adequate solutions to these problems have not yet been found.&lt;/p&gt;&lt;p&gt;The second question is whether there is a need for more than two tests using next-generation sequencing. The study by Ishida et al. is a high-impact paper discussing the usefulness of comprehensive genomic profiling assays.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; (In their paper, comprehensive genomic profiling assays refers to FoundationOne and the OncoGuide NCC Oncopanel System.) Their paper demonstrated that new targets were found in people who had already undergone a gene test and subsequently undergone comprehensive genomic profiling assays. Noteworthy in their paper are the details of the 20 individuals for whom new therapeutic targets were found. Was their first test a single-plex test or an Oncomine Dx Target Test Multi-CDx? What were the histological type, sex, and smoking history of theese 20 patients? These information will help us determine which patients should undergo comprehensive genomic profiling assays.

Therefore, the information on UM patients from the SEER database (2000–2020) was split into a 7:3 ratio training set and an internal test set based on distant metastasis presence. Univariate and multivariate logistic regression analyses assessed distant metastasis risk factors. Six machine learning methods constructed a predictive model post-feature variable selection. The model evaluation identified the multilayer perceptron (MLP) as optimal. Shapley additive explanations (SHAP) interpreted the chosen model. A web-based calculator personalized risk probabilities for UM patients. The results show that nine feature variables contributed to the machine learning model. The MLP model demonstrated superior predictive accuracy (Precision = 0.788; ROC AUC = 0.876; PR AUC = 0.788). Grade recode, age, primary site, time from diagnosis to treatment initiation, and total number of malignant tumors were identified as distant metastasis risk factors. Diagnostic method, laterality, rural–urban continuum code, and radiation recode emerged as protective factors. The developed web calculator utilizes the MLP model for personalized risk assessments.

However, the underlying molecular mechanisms remain unclear. Long-chain acyl-CoA synthetase 4 (ACSL4), which catalyzes fatty acids to form fatty acyl-CoAs, is critical for synthesizing phospholipids or triglycerides. Despite the differing roles of ACSL4 in cancers, our data showed that ACSL4 was highly expressed in HNSCC tissues, positively correlating with poor survival rates in patients. Knockdown of ACSL4 in HNSCC cells led to reduced cell proliferation and invasiveness. RNA sequencing analyses identified interferon-induced protein 44 (IFI44) and interferon-induced protein 44-like (IFI44L), encoded by two interferon-stimulated genes, as potential effectors of ACSL4. Silencing IFI44 or IFI44L expression in HNSCC cells decreased cell proliferation and invasiveness. Manipulating ACSL4 expression or activity modulated the expression levels of JAK1, tyrosine kinase 2 (TYK2), signal transducer and activator of transcription 1 (STAT1), interferon α (IFNα), IFNβ, and interferon regulatory factor 1 (IRF1), which regulate IFI44 and IFI44L expression. Knockdown of IRF1 reduced the expression of JAK1, TYK2, IFNα, IFNβ, IFI44, or IFI44L and diminished cell proliferation and invasiveness.

We incorporated 14 blood metabolic indicators and identified independent prognostic indicators for overall survival through univariate and multivariate analyses. Subsequently, a metabolism score formula was established based on the biochemical markers. We constructed a nomogram and machine learning models utilizing the metabolism score and clinically significant prognostic features, followed by an evaluation of their predictive accuracy and performance.

The brain microenvironment consists of unique resident cell types such as neurons, oligodendrocytes, astrocytes, and microglia. Accumulating evidence over the past decades suggests that the interactions between cancer cells and glial cells can positively or negatively influence the development of brain metastasis. Nevertheless, elucidating the complex interactions between cancer cells and glial cells remains challenging, in part due to the limitations of existing experimental models for glial cell culture.
