Delta-Radiomics Using Machine Learning Classifiers With Auxiliary Data Sets to Predict Disease Progression During Magnetic Resonance-Guided Radiotherapy in Adrenal Metastases.

Purpose: Adaptive radiotherapy accounts for interfractional anatomic changes. We hypothesize that changes in the gross tumor volumes identified during daily scans could be analyzed using delta-radiomics to predict disease progression events. We evaluated whether an auxiliary data set could improve prediction performance.

The exceptionally rare phenomenon of well-differentiated colon neuroendocrine tumors.

Colonic neuroendocrine tumors (NETs), excluding rectal NETs, are often described as relatively common and aggressive, with inferior median survival compared with other gastrointestinal (GI) primary sites. However, epidemiological databases may conflate well-differentiated NETs with poorly differentiated neuroendocrine carcinomas (NECs), leading to a lack of precise data on the prevalence, clinical behavior, and prognosis of well-differentiated colonic NETs. We analyzed a large institutional database to identify patients with well-differentiated NETs originating in the colon, excluding rectal NETs.

Chlamydia muridarum Causes Persistent Subclinical Infection and Elicits Innate and Adaptive Immune Responses in C57BL/6J, BALB/cJ, and J:ARC(S) Mice Following Exposure to Shedding Mice.

Chlamydia muridarum (Cm) has reemerged as a moderately prevalent infectious agent in research mouse colonies. Despite its experimental use, few studies evaluate Cm's effects on immunocompetent mice following its natural route of infection. A Cm field isolate was administered (orogastric gavage) to 8-wk-old female BALB/cJ (C) mice.

Comprehensive Analysis Identifies as a Potential Prognostic and Immunological Biomarker in Glioblastoma.

Glioblastoma (GBM) is a highly aggressive brain tumor characterized by its ability to evade the immune system, hindering the efficacy of current immunotherapies. Recent research has highlighted the important role of immunosuppressive macrophages in the tumor microenvironment (TME) in driving this immune evasion. In this study, we are the first to identify as a key regulator of tumor-associated macrophage (TAM)-mediated immunosuppression in GBM.

Outcomes in stage IIA versus stage IIB/III in the PALLAS trial [ABCSG-42/AFT-05/PrE0109/BIG-14-13]).

Background: The PALLAS trial investigated the addition of palbociclib to standard adjuvant endocrine therapy to reduce breast cancer recurrence. This pre-specified analysis was conducted to determine whether adjuvant palbociclib benefited patients diagnosed with lower risk stage IIA disease compared to those with higher stage disease.

Methods: PALLAS was an international, multicenter, randomized, open-label, phase III trial, representing a public-private partnership between Pfizer, the Austrian Breast Cancer Study Group, and the U.

Long-term smoking contributes to aging frailty and inflammatory response.

In recent years, the health challenges linked to frailty in the elderly, particularly those worsened by cigarette smoke, have become more pronounced. However, quantitative studies examining the impact of smoking dosage on frailty in this population remain limited. To address this gap, we developed a model using smoke-exposed elderly mice.

Genetic insights and therapeutic avenues: unraveling the role of polyunsaturated fatty acids as mediators between hypothyroidism and Von Willebrand disease through Mendelian randomization.

Background: Previous observational studies have shown that Hypothyroidism is associated with Von Willebrand Disease (VWD), but the causal relationship has not been confirmed because of conflicting findings and confounding by mixing factors. There are also some studies suggesting that polyunsaturated fatty acids (PUFA) may be one of the potential mediators. In this study, we used a Mendelian randomization study to analyze the causal relationship between Hypothyroidism and VWD and to investigate whether polyunsaturated fatty acids mediate the effects of Hypothyroidism on VWD.

gene mutation through CRISPR RNA-guided base editing weakens bacterial virulence and immune evasion.

The resistance of commonly used clinical antibiotics, such as daptomycin (DAP), has become increasingly serious in the fight against () infection. It is essential to explore key pathogenicity-driven genes/proteins in bacterial infection and antibiotics resistance, which contributes to develop novel therapeutic strategies against infections. The gene of , encoding 5'-nucleotidase (NT5), is nearly unknown for its function in drug resistance and bacterial infection.

A novel piperine derivative HJJ_3_5 inhibits colorectal cancer progression by modulating EMT signaling pathways.

Colorectal cancer (CRC) is a fatal cancer prevalent worldwide, and epithelial-mesenchymal transition (EMT) is a key factor in tumor invasion and metastasis. Piperine, a natural alkaloid known for its antitumor properties, faces limitations in clinical use due to its moderate potency. To address this, our team synthesized and validated a new derivative, HJJ_3_5, which has shown potent antitumor activity against CRC cells.

Immunogenicity of the 9-valent human papillomavirus vaccine: Post hoc analysis from five phase 3 studies.

Post hoc analyses of 9-valent human papillomavirus (9vHPV) vaccine immunogenicity were conducted in five Phase 3 studies that enrolled males. Month 7 antibody geometric mean titers (GMTs) after three 9vHPV vaccine doses were analyzed in 10,024 males/females aged 16-26 years from studies 001 (NCT00543543), 002 (NCT00943722), 003 (NCT01651949), and 020 (NCT02114385). Covariates considered were age, gender, sexual orientation, region of residence, and race.

Mouse models of Kaposi sarcoma-associated herpesvirus (KSHV).

Infection with Kaposi sarcoma-associated herpesvirus (KSHV) is a prerequisite for the development of several human cancers, including Kaposi sarcoma and primary effusion lymphoma. Efficient long-term infection with KSHV and subsequent virally induced cell transformation is limited to humans, resulting in a lack of small animal models for KSHV-driven malignancies. Various attempts to create a mouse model for KSHV include infection of humanized mice, generating transgenic mice that ectopically express viral proteins, and grafting KSHV-infected tumor, primary, or immortalized cells onto immunodeficient mice.

Letetresgene Autoleucel in Advanced/Metastatic Myxoid/Round Cell Liposarcoma.

Purpose: The cancer/testis antigen New York esophageal squamous cell carcinoma 1 (NY-ESO-1) is a promising target in myxoid/round cell liposarcoma (MRCLS).

Methods: In this pilot study, we assessed the adoptive T-cell therapy NY-ESO-1cT letetresgene autoleucel (lete-cel) in patients with human leukocyte antigen (HLA)-A*02:01-, HLA-A*02:05-, and/or HLA-A*02:06-positive advanced/metastatic NY-ESO-1-expressing MRCLS. Patients underwent a reduced-dose (cohort 1) or standard-dose (cohort 2) lymphodepletion regimen (LDR).

Secernin-2 Stabilizes Histone Methyltransferase KMT2C to Suppress Progression and Confer Therapeutic Sensitivity to PARP Inhibition in Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is a difficulty and bottleneck in the clinical treatment of breast cancer due to a lack of effective therapeutic targets. Herein, we first report that secernin 2 (SCRN2), an uncharacterized gene in human cancer, acts as a novel tumor suppressor in TNBC to inhibit cancer progression and enhance therapeutic sensitivity to poly(ADP-ribose) polymerase (PARP) inhibition both in vitro and in vivo. SCRN2 is downregulated in TNBC through chaperone-mediated autophagic degradation, and its downregulation is associated with poor patient prognosis.

Drug development is a complex and time-consuming endeavor that traditionally relies on the experience of drug developers and trial-and-error experimentation. The advent of artificial intelligence (AI) technologies, particularly emerging large language models and generative AI, is poised to redefine this paradigm. The integration of AI-driven methodologies into the drug development pipeline has already heralded subtle yet meaningful enhancements in both the efficiency and effectiveness of this process.

Manganese dioxide-based in situ vaccine boosts antitumor immunity via simultaneous activation of immunogenic cell death and the STING pathway.

In situ vaccine (ISV) can activate the anti-tumor immune system by inducing immunogenic cell death (ICD) at the tumor site. However, the development of tumor ISV still faces challenges due to insufficient tumor antigens released by tumor cells and the existence of tumor immunosuppressive microenvironment (TIME). Targeting the STING pathway has been reported to enhance the adjuvant effects of in situ tumor vaccines by initiating innate immunity.

Identification of MORF4L1 as an endogenous substrate of CRBN and its potential role as a therapeutic target in cancer.

The ubiquitin-proteasome system (UPS) is essential for cellular homeostasis, regulating the degradation of proteins involved in key processes such as cell cycle, apoptosis, and DNA repair. Dysregulation of the UPS is implicated in hepatocellular carcinoma (HCC), contributing to tumor progression and therapeutic resistance. The cereblon (CRBN) E3 ubiquitin ligase complex is a crucial component of the UPS, particularly in modulating protein degradation in response to small-molecule modulators like thalidomide.

Tucatinib and trastuzumab in HER2-mutated metastatic breast cancer: a phase 2 basket trial.

Human epidermal growth factor receptor 2 (HER2, also known as ERBB2) signaling promotes cell growth and differentiation, and is overexpressed in several tumor types, including breast, gastric and colorectal cancer. HER2-targeted therapies have shown clinical activity against these tumor types, resulting in regulatory approvals. However, the efficacy of HER2 therapies in tumors with HER2 mutations has not been widely investigated.

Discordance, accuracy and reproducibility study of pathologists' diagnosis of melanoma and melanocytic tumors.

Accurate melanoma diagnosis is crucial for patient outcomes and reliability of AI diagnostic tools. We assess interrater variability among eight expert pathologists reviewing histopathological images and clinical metadata of 792 melanoma-suspicious lesions prospectively collected at eight German hospitals. Moreover, we provide access to the largest panel-validated dataset featuring dermoscopic and histopathological images with metadata.

Idecabtagene vicleucel or ciltacabtagene autoleucel for relapsed or refractory multiple myeloma: An international multicenter study.

Idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel) have revolutionized the treatment of relapsed/refractory multiple myeloma (RRMM), but direct comparisons are lacking. Leveraging an international multicenter RRMM cohort, we compared the outcome of ide-cel ( = 162) versus cilta-cel ( = 42). Co-primary efficacy endpoints of the study were overall response rate (ORR) and progression-free survival (PFS).

Better Outcomes for Ovarian Cancer Associated With the Detection of Anti-EBV TCR CDR3s: Potential Relevance to Diffuse Large B-Cell Lymphoma.

Objectives: Given the ongoing challenges regarding the specific roles of viral infections in cancer etiology, or as cancer co-morbidities, this study assessed potential associations between anti-viral, T-cell receptor (TCR) complementarity domain region-3 (CDR3s), and clinical outcomes for ovarian cancer.

Methods: TCR CDR3s were isolated from ovarian cancer specimens for a determination of which patients had anti-viral CDR3s and whether those patients had better or worse outcomes.

Results: Analyses revealed that patients with exact matches of anti-Epstein-Barr virus (EBV) CDR3 amino acid sequences exhibited better outcomes for both overall and disease-specific survival.

B cells enhance IL-1 beta driven invasiveness in triple negative breast cancer.

Triple-negative breast cancer (TNBC) is an aggressive subtype often characterized by high lymphocyte infiltration, including tumor-infiltrating B cells (TIBs). These cells are present even in early stages of TNBC and associated with microinvasion. This study shows that co-culturing TNBC cells with B cells increases Interleukin-1β (IL-1β) expression and secretion.
