Precision targeting of β-catenin induces tumor reprogramming and immunity in hepatocellular cancers.

First-line immune checkpoint inhibitor (ICI) combinations show responses in subsets of hepatocellular carcinoma (HCC) patients. Nearly half of HCCs are Wnt-active with mutations in (encoding for β-catenin), , or , and demonstrate limited benefit to ICI due to an immune excluded tumor microenvironment. We show significant tumor responses in multiple β-catenin-mutated immunocompetent HCC models to a novel siRNA encapsulated in lipid nanoparticle targeting (LNP-CTNNB1).

Assessment of adenosinergic activity of small extracellular vesicles in plasma of cancer patients and healthy donors.

The adenosinergic pathway converting endogenous ATP to adenosine (ADO) is a major immunosuppressive pathway in cancer. Emerging data indicate that plasma small extracellular vesicles (sEV) express CD39 and CD73 and produce ADO. Using a noninvasive, highly sensitive newly developed assay, metabolism of N-etheno-labeled eATP, eADP or eAMP by ecto-nucleotidases on the external surface of sEV was measured using high pressure liquid chromatography with fluorescence detection.

The EstroGene2.0 database for endocrine therapy response and resistance in breast cancer.

Endocrine therapies targeting the estrogen receptor (ER/ESR1) are the cornerstone to treat ER-positive breast cancers patients, but resistance often limits their effectiveness. Notable progress has been made although the fragmented way data is reported has reduced their potential impact. Here, we introduce EstroGene2.

Structure-Activity Relationship Study of Splicing Modulators on Hsh155/SF3B1 through Chemical Synthesis and Yeast Genetics.

Meayamycins are synthetic analogs of the natural product FR901464 and exhibit potent anticancer activity against human cancers. They bind SF3B1 and PHF5A, components of the human spliceosome, and they alter pre-mRNA splicing. Detailed analysis of the active site led us to investigate a narrow pocket within the binding site that surrounds the α,β-unsaturated amide portion of meayamycin.

The Evolving Role of the Oncology Nurse in the United States of America-A Survey Exploring Their Perspective.

Background: The role of the oncology nurse has evolved since the COVID-19 pandemic to continuously meet patient needs, resulting in an increased virtual presence. However, there is little information about whether these roles have continued since the pandemic and how it is affecting nurses.

Methods: The aim of this study, conducted via an electronic survey questionnaire, was to examine the perspective of oncology nurses in the United States of America regarding how their role has changed, the adaptation to telehealth, challenges, and needs.

Hypoxia-Inducible Factor-2α Promotes Liver Fibrosis by Inducing Hepatocellular Death.

The activation of hypoxia-inducible factors (HIF)-1α and 2α in the liver is closely linked to the progression of fatty liver diseases. Prior studies indicated that disrupting hepatocyte HIF-2α attenuates diet-induced hepatic steatosis, subsequently decreasing fibrosis. However, the direct role of hepatocyte HIF-2α in liver fibrosis has not been addressed.

A direct interaction between the Chd1 CHCT domain and Rtf1 controls Chd1 distribution and nucleosome positioning on active genes.

The nucleosome remodeler Chd1 is required for the re-establishment of nucleosome positioning in the wake of transcription elongation by RNA Polymerase II. Previously, we found that Chd1 occupancy on gene bodies depends on the Rtf1 subunit of the Paf1 complex in yeast. Here, we identify an N-terminal region of Rtf1 and the CHCT domain of Chd1 as sufficient for their interaction and demonstrate that this interaction is direct.

Background & Aims: Integrated HBV DNA (iDNA) plays a critical role in HBV pathogenesis, particularly in predicting treatment response and HCC. This study aimed to use an HBV hybridization-capture next-generation sequencing (HBV-NGS) assay to detect HBV-host junction sequences (HBV-JS) in a sensitive nonbiased manner to detect and estimate the iDNA fraction in tissue biopsies and HBV genetics by liquid biopsy.

Methods: HBV DNA from plasmid monomers, HBV-HCC cell line (SNU398, Hep3B, and PLC/PRF/5), tissue biopsies of patients with serum HBV DNA <4 log IU/ml, and matched urine and plasma of HBV patients were assessed by HBV-NGS.

Systematic Review of the Comparative Studies of Image-guided Thermal Ablation, Stereotactic Radiosurgery, and Sublobar Resection for Treatment of High-Risk Patients with Stage I Non-Small Cell Lung Cancer.

The Clinical Practice Standards Committee of the American Association for Thoracic Surgery assembled an expert panel and conducted a systematic review of the literature detailing studies directly comparing treatment options for high-risk patients with stage I non-small cell lung cancer (NSCLC). A systematic search was performed to identify publications comparing outcomes following image-guided thermal ablation (IGTA), stereotactic ablative radiotherapy (SABR), and sublobar resection-the main treatment options applicable to high-risk patients with stage I NSCLC. There were no publications detailing completed randomized controlled trials comparing these treatment options.

Systematic Review of Stereotactic Ablative Radiotherapy (SABR)/ Stereotactic Body Radiation Therapy (SBRT) for Treatment of High-Risk Patients with Stage I Non-Small Cell Lung Cancer.

Stereotactic ablative radiotherapy (SABR) has emerged as an alternative, non-surgical treatment for high-risk patients with stage I non-small cell lung cancer (NSCLC) with increased use over time. The American Association for Thoracic Surgery (AATS) Clinical Practice Standards Committee (CPSC) assembled an expert panel and conducted a systematic review of the literature evaluating the results of SABR, which is also referred to as stereotactic body radiation therapy (SBRT) or stereotactic radiosurgery (SRS), prior to developing treatment recommendations for high-risk patients with stage I NSCLC based on expert consensus. Publications detailing the findings of 16 prospective studies of SABR and 14 retrospective studies of SABR for the management of early-stage lung cancer in 54 697 patients were identified by systematic review of the literature with further review by members of our expert panel.

Systematic Review of Sublobar Resection for Treatment of High-Risk Patients with Stage I Non-Small Cell Lung Cancer.

Sublobar resection offers a parenchymal-sparing surgical alternative to lobectomy and includes wedge resection and segmentectomy. Sublobar resection has been historically utilized in high-risk patients with compromised lung function; however, the technique is becoming more prevalent for normal-risk patients with peripheral lung tumors < 2 cm. In this article, we summarize the technique of sublobar resection, the importance of surgical margins and lymph node sampling, patient selection, perioperative complications, outcomes, and the impact of sublobar resection on the quality of life.

Structural insight into CD20/CD3-bispecific antibodies by molecular modeling.

Non-Hodgkin's Lymphoma (NHL) remains a significant challenge in hematology, with chemotherapy and radiation therapy as conventional treatment options, albeit with limitations such as adverse effects. Immunotherapy, particularly bispecific antibodies (BsAbs) T cell engagers (TCEs), has emerged as a promising approach. Despite their potential, TCEs pose challenges, including adverse events like cytokine release syndrome.
