Programmed cell death in nasopharyngeal carcinoma: Mechanisms and therapeutic targets.

Programmed cell death is a type of autonomic and orderly cell death mode controlled by genes that maintain homeostasis and growth. Tumor is a typical manifestation of an imbalance in environmental homeostasis in the human body. Currently, several tumor treatments are designed to trigger the death of tumor cells.

Random walk models in the life sciences: including births, deaths and local interactions.

Random walks and related spatial stochastic models have been used in a range of application areas, including animal and plant ecology, infectious disease epidemiology, developmental biology, wound healing and oncology. Classical random walk models assume that all individuals in a population behave independently, ignoring local physical and biological interactions. This assumption simplifies the mathematical description of the population considerably, enabling continuum-limit descriptions to be derived and used in model analysis and fitting.

Mitochondrial chaperonin DNAJC15 promotes vulnerability to ferroptosis of chemoresistant ovarian cancer cells.

DNAJC15 is a mitochondrial TIMM23-related co-chaperonin known for its role in regulating oxidative phosphorylation efficiency, oxidative stress response and lipid metabolism. Recently, it has been proposed that the loss of DNAJC15 correlates with cisplatin (CDDP)-resistance onset in ovarian cancer (OC), suggesting this protein as a potential prognostic factor during OC progression. However, the molecular mechanisms through which DNAJC15 contributes to CDDP response remains poorly investigated.

Itaconate transporter SLC13A3 confers immunotherapy resistance via alkylation-mediated stabilization of PD-L1.

Itaconate is a metabolite catalyzed by cis-aconitate decarboxylase (ACOD1), which is mainly produced by activated macrophages and secreted into the extracellular environment to exert complex bioactivity. In the tumor microenvironment, itaconate is concentrated and induces an immunosuppressive response. However, whether itaconate can be taken up by tumor cells and its mechanism of action remain largely unclear.

Clonally expanded, targetable, natural killer-like NKG7 T cells seed the aged spinal cord to disrupt myeloid-dependent wound healing.

Spinal cord injury (SCI) increasingly affects aged individuals, where functional impairment and mortality are highest. However, the aging-dependent mechanisms underpinning tissue damage remain elusive. Here, we find that natural killer-like T (NKLT) cells seed the intact aged human and murine spinal cord and multiply further after injury.

Genomic and phenotypic correlates of mosaic loss of chromosome Y in blood.

Mosaic loss of Y (mLOY) is the most common somatic chromosomal alteration detected in human blood. The presence of mLOY is associated with altered blood cell counts and increased risk of Alzheimer disease, solid tumors, and other age-related diseases. We sought to gain a better understanding of genetic drivers and associated phenotypes of mLOY through analyses of whole-genome sequencing (WGS) of a large set of genetically diverse males from the Trans-Omics for Precision Medicine (TOPMed) program.

High cellular plasticity state of medulloblastoma local recurrence and distant dissemination.

Medulloblastoma (MB), a heterogeneous pediatric brain tumor, poses challenges in the treatment of tumor recurrence and dissemination. To characterize cellular diversity and genetic features, we comprehensively analyzed single-cell/nucleus RNA sequencing (sc/snRNA-seq), single-nucleus assay for transposase-accessible chromatin sequencing (snATAC-seq), and spatial transcriptomics profiles and identified distinct cellular populations in SHH (sonic hedgehog) and Group_3 subgroups, with varying proportions in local recurrence or dissemination. Local recurrence showed higher cycling tumor cell enrichment, whereas disseminated lesions had a relatively notable presence of differentiated subsets.

Single-molecule systems for the detection and monitoring of plasma-circulating nucleosomes and oncoproteins in diffuse midline glioma.

The analysis of cell-free tumor DNA (ctDNA) and proteins in the blood of patients with cancer potentiates a new generation of non-invasive diagnostic approaches. However, confident detection of tumor-originating markers is challenging, especially in the context of brain tumors, where these analytes in plasma are extremely scarce. Here, we apply a sensitive single-molecule technology to profile multiple histone modifications on individual nucleosomes from the plasma of patients with diffuse midline glioma (DMG).

Introduction: Health-related quality of life (HRQOL) has been reported in clinical trials of pembrolizumab and avelumab treatment of locally advanced or metastatic urothelial carcinoma. However, few studies have investigated the effect of immune checkpoint inhibitors (ICIs) on HRQOL in patients with urothelial carcinoma in a real-world setting.

Methods: We included 44 patients with advanced urothelial cancer who were treated with pembrolizumab or avelumab from January 2018 to November 2023.

Non-small cell lung cancer treated with epidermal growth factor receptor inhibitors: the effect of concurrent medications on patient outcomes.

Introduction: EGFR tyrosine kinase inhibitor (TKI)-induced rash can be alleviated with tetracyclines (TCN) and topical corticosteroids (TCS), whereas drugs for acid-related disorders (DARD) can affect EGFR TKI absorption. The present study investigated the concomitant use of TCNs, TCSs, and DARDs with EGFR-TKIs in non-small cell lung cancer (NSCLC) and whether these affect patient outcomes.

Methods: We retrospectively collected data from all patients (n=1498) who had purchased for EGFR TKIs (erlotinib, gefitinib, and afatinib) in Finland between 2011-2020.

Causal effect of C-reaction protein and endometrial cancer: Genetic evidence of the role of inflammation in endometrial cancer.

Consensus remains elusive regarding the relationship between C-reactive protein (CRP) levels and endometrial cancer (EC). Our study sought to elucidate the causal association between CRP and EC, aiming to contribute to the understanding of this complex interplay. We primarily utilized the random-effects inverse variance-weighted method.

Identification and validation of a novel defined stress granule-related gene signature for predicting the prognosis of ovarian cancer via bioinformatics analysis.

Ovarian cancer (OC) is a malignant gynecological cancer with an extremely poor prognosis. Stress granules (SGs) are non-membrane organelles that respond to stressors; however, the correlation between SG-related genes and the prognosis of OC remains unclear. This systematic analysis aimed to determine the expression levels of SG-related genes between high- and low-risk groups of patients with OC and to explore the prognostic value of these genes.

Phantom evaluation of feasibility and applicability of artificial intelligence based pulmonary nodule detection in chest radiographs.

The aim of our study was to evaluate the specific performance of an artificial intelligence (AI) algorithm for lung nodule detection in chest radiography for a larger number of nodules of different sizes and densities using a standardized phantom approach. A total of 450 nodules with varying density (d1 to d3) and size (3, 5, 8, 10 and 12 mm) were inserted in a Lungman phantom at various locations. Radiographic images with varying projections were acquired and processed using the AI algorithm for nodule detection.

Investigations have indicated that there is a correlation between thyroid nodules and patients'negative emotions. Nevertheless, the risk factors contributing to the development of negative emotions in thyroid nodule patients remain unidentified. This cross-sectional study recruited 150 patients diagnosed with thyroid nodules through ultrasound examination from January 2022 to January 2023 at Jinan Central Hospital, the Second Affiliated Hospital of Shandong First Medical University, and Qingyun County Maternal and Child Health Hospital as the case group, which were categorized based on their levels of anxiety and depression.

Prophylactic cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for low-grade appendiceal mucinous tumors with early and limited disease after completely removed.

The necessity of prophylactic cytoreductive surgery (PCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for low-grade appendiceal mucinous neoplasms (LAMN) after complete removal is still controversial. This study aims to determine the role of PCRS + HIPEC and identify optimal strategies for managing these patients. One hundred fifty-nine patients who sought medical advice at Aerospace Center Hospital were retrospectively analyzed from January 2011 to December 2021.

Evaluation of ixabepilone efficacy and tolerability in metastatic breast cancer.

Although microtubule inhibitors are generally used in advanced stages, they provide the opportunity to prolong survival as an alternative when medical oncologists have difficulty finding options in their patients, who typically have a poor prognosis and most of whom are unresponsive to treatment. For this reason, we wanted to investigate the effect of ixabepilone treatment on survival in earlier metastatic lines. Our study also examined the frequency of side effects and survival differences in patients whose dose was reduced or whose treatment was discontinued.

The associations between risk factors and pituitary neuroendocrine tumors: A bidirectional Mendelian randomization study.

The etiological basis of pituitary neuroendocrine tumors is uncertain. We used Mendelian randomization technique to investigate the potential influence of several risk factors on the likelihood of developing pituitary neuroendocrine tumors. We admitted 8 risk factors, divided into 3 lifestyle factors and 5 chronic diseases as exposure factors.

Lateral center-edge angle in femoroacetabular impingement: from the sourcil or the rim of the acetabulum?

The correlation between clinical outcomes and preoperative/postoperative measures of the lateral center-edge angle (LCEA) will help establish the cutoff values for this measurement and determine whether to obtain it from the lateral acetabular rim (LCEAR) or the lateral end of the sourcil (LCEAS). The hypothesis was that the LCEAS would be more sensitive than the LCEAR. An upper cutoff value of LCEA could predict better functional outcomes in FAI patients.

Exploring the gut-inflammation connection: A Mendelian randomization study on gut microbiota, inflammatory factors, and uterine fibroids risk.

This study employs Mendelian randomization (MR) approach to investigate the potential causal association between genetic variants associated with gut microbiota, inflammatory factors, and the risk of uterine fibroids development. We extracted data on 211 types of gut microbiota, 91 inflammatory factors, and uterine fibroids occurrence from genome-wide association studies and applied the inverse-variance weighted (IVW) method for analysis. To further assess the robustness of our MR analysis, we conducted sensitivity tests including Cochrane's Q test, the MR-Egger intercept test, the MR-PRESSO global test, and a leave-one-out analysis.

The connection between Primary sclerosing cholangitis (PSC) and lymphoma remains uncertain. To address this, Mendelian randomization (MR) was utilized to investigate the potential causal links between PSC and lymphoma. A 2-sample MR analysis was conducted utilizing summary-level data obtained from genome-wide association study datasets.

Bioinformatics-based analysis of the role of immune-related genes in acute rejection after kidney transplantation and renal cancer development.

Acute rejection (AR) is a common complication in the early stage after kidney transplantation. Some studies have shown that the occurrence of AR after kidney transplantation may further affect the development of tumors, and both AR and tumor development are related to immune cells and immune genes, so it is particularly important to diagnose the occurrence of AR at an early stage and to analyze the correlation between AR and tumors. In this study, we applied bioinformatics techniques for differential expression analysis and weighted gene co-expression network analysis analysis of AR patients to obtain differentially expressed genes and modular genes significantly associated with AR, respectively, so as to obtain their intersecting genes with immune-related genes; 21 intersecting genes were screened by lasso regression and Boruta algorithm to obtain the genes, and finally, the feature genes that were significantly associated with the dependent variable were further obtained by single-factor and multi-factor logistic regression.
