LHX3 promotes EMT in hepatoma cell through β-catenin/TCF4 pathway.

Hepatocellular carcinoma (HCC) is a highly malignant cancer and lacks effective therapeutic targets. The role of LIM/homeobox protein Lhx3 (LHX3) has been extensively studied in various tumor tissues, where it has been identified as a promoter of tumorigenesis and malignancy. However, the specific functional role and potential mechanism of LHX3 in human HCCs are not clearly clarified.

Her2 promotes early dissemination of breast cancer by inhibiting the p38 pathway through the downregulation of MAP3K4.

Early dissemination refers to the process by which cancer cells spread to distant organs at an early stage of the disease, often before the primary tumor is clinically detectable. Experimental studies have demonstrated that Her2 promotes early dissemination of breast cancer by inhibiting the p38 signaling pathway. However, the precise mechanism by which Her2 suppresses the activation of p38 signaling in early-stage cancer cells (ECCs) remains unclear.

A novel dicyanoisophorone-based fluorescent probe for rapid detection of acetylcholinesterase in biological systems.

Acetylcholinesterase (AChE) plays a vital role in various neurological diseases including brain disorders, neurotransmission alterations, and cancer. Developing effective methods to image AChE in biological samples is essential for understanding its mechanisms in biosystems. Here, we introduce a novel fluorescent probe CNA, that enables detection of AChE at 520 nm with rapid response time of 60 s and a detection limit of 0.

Coronary computed tomography angiography for assessing the coronary artery and predicting adverse cardiovascular events in patients with thoracic malignancies.

Background: It is unclear whether the parameters derived from coronary computed tomography angiography (CCTA) can identify the impairments of coronary arteries and if they are associated with major adverse cardiovascular events (MACEs) in patients with thoracic malignancies receiving chemotherapy or chemoradiotherapy. This study aimed to investigate the longitudinal changes in coronary arteries using CCTA and to determine their association with MACEs in patients with thoracic malignancies receiving chemotherapy or chemoradiotherapy.

Methods: This cross-sectional study included consecutive patients with thoracic malignancies who received chemotherapy or chemoradiotherapy and who underwent CCTA between June 2013 and May 2019 at Chongqing University Cancer Hospital.

Ultrasound nanodroplets loaded with Siglec-G siRNA and FeO activate macrophages and enhance phagocytosis for immunotherapy of triple-negative breast cancer.

Background: The progression of triple-negative breast cancer is shaped by both tumor cells and the surrounding tumor microenvironment (TME). Within the TME, tumor-associated macrophages (TAMs) represent a significant cell population and have emerged as a primary target for cancer therapy. As antigen-presenting cells within the innate immune system, macrophages are pivotal in tumor immunotherapy through their phagocytic functions.

ZDHHC20 mediated S-palmitoylation of fatty acid synthase (FASN) promotes hepatocarcinogenesis.

Background: Protein palmitoylation is a reversible fatty acyl modification that undertakes important functions in multiple physiological processes. Dysregulated palmitoylations are frequently associated with the formation of cancer. How palmitoyltransferases for S-palmitoylation are involved in the occurrence and development of hepatocellular carcinoma (HCC) is largely unknown.

Estimation of adaptive radiation therapy requirements for rectal cancer: a two-center study.

Background: Rectal cancer patients are potential beneficiaries of adaptive radiotherapy (ART) which demands considerable resources. Currently, there is no definite guidance on what kind of patients and when will benefit from ART. This study aimed to develop and validate a methodology for estimating ART requirements in rectal cancer before treatment course.

Asymmetrically PEGylated and amphipathic heptamethine indocyanine dyes potentiate radiotherapy of renal cell carcinoma via mitochondrial targeting.

Enhancing the sensitivity of radiotherapy (RT) towards renal cell carcinoma (RCC) remains a challenge because RCC is a radioresistant tumor. In this work, we design and report asymmetrically Polyethylene Glycol (PEG)ylated and amphipathic heptamethine indocyanine dyes for efficient radiosensitization of RCC treatment. They were synthesized by modifying different lengths of PEG chains as hydrophilic moieties on one N-alkyl chain of a mitochondria-targeting heptamethine indocyanine dye (IR-808), and a radiosensitizer 2-nitroimidazole (NM) as a hydrophobic moiety on another N-alkyl chain.

Epoxy metabolites of linoleic acid promote the development of breast cancer via orchestrating PLEC/NFκB1/CXCL9-mediated tumor growth and metastasis.

Breast cancer (BC) is a common malignant tumor in women and requires a comprehensive understanding of its pathogenesis for the development of new therapeutic strategies. Polyunsaturated fatty acids (PUFAs) metabolism-driven inflammation is a causative factor in cancer development. However, the function of PUFAs' metabolism in BC remains largely unknown.

Evaluation of gecacitinib vs hydroxyurea in patients with intermediate-2 or high-risk myelofibrosis: final analysis results from a randomized phase 3 study.

To compare the efficacy and safety of gecacitinib (also known as jaktinib) with hydroxyurea (HU) in treating myelofibrosis (MF) patients. In this multicenter, randomized phase 3 trial (ZGJAK016), intermediate- or high-risk primarily JAK inhibitor naïve MF patients were assigned in a 2:1 ratio to receive either gecacitinib (100 mg twice a day, BID) or HU (500 mg BID). The primary endpoint was the proportion of patients with ≥35% reduction in spleen volume (SVR35) from baseline at week 24.

Development and validation of disulfidptosis-related genes signature for patients with glioma.

Background: Disulfidptosis has recently emerged as a novel form of regulated cell death (RCD). Evasion of cell death is a hallmark of cancer, and the resistance of many tumors to apoptosis-inducing therapies has heightened interest in exploring alternative RCD mechanisms.

Methods: Transcriptomic and clinical data were obtained from The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx), and Chinese Glioma Genome Atlas (CGGA).

CB2R activation enhances tumor-associated macrophages-mediated phagocytosis of glioma cell.

Background: Cannabinoid administration has demonstrated promising anti-tumor effects for glioblastoma (GBM) by inhibiting glioma cell proliferation and inducing glioma cell death. However, the impact of cannabinoids and endocannabinoid receptors on immune cells within the tumor microenvironment (TME) remains largely unexplored. Tumor-associated macrophages (TAMs), the most abundant immune cells in the TME, and their mediated phagocytosis of tumor cells have shown potential in preclinical xenografts of various human malignancies.

A novel computational model ITHCS for enhanced prognostic risk stratification in ESCC by correcting for intratumor heterogeneity.

Intratumor heterogeneity significantly challenges the accuracy of existing prognostic models for esophageal squamous cell carcinoma (ESCC) by introducing biases related to the varied genetic and molecular landscapes within tumors. Traditional models, relying on single-sample, single-region bulk RNA sequencing, fall short of capturing the complexity of intratumor heterogeneity. To fill this gap, we developed a computational model for intratumor heterogeneity corrected signature (ITHCS) by employing both multiregion bulk and single-cell RNA sequencing to pinpoint genes that exhibit consistent expression patterns across different tumor regions but vary significantly among patients.

Patient-reported outcomes of rezvilutamide versus bicalutamide in combination with androgen deprivation therapy in high-volume metastatic hormone-sensitive prostate cancer patients (CHART): a randomized, phase 3 study.

The randomized phase 3 CHART trial (NCT03520478) revealed that rezvilutamide (REZ) plus androgen deprivation therapy (ADT) in high-volume, metastatic, hormone-sensitive prostate cancer (mHSPC) significantly enhanced radiographic progression-free and overall survival than bicalutamide (BIC)-ADT. Accordingly, we examined patient-reported outcomes (PROs) results, which were exploratory endpoints in the CHART trial. The patients were randomly allocated to receive REZ-ADT or BIC-ADT in a 1:1 ratio.

Near-Infrared Optogenetic Nanosystem for Spatiotemporal Control of CRISPR-Cas9 Gene Editing and Synergistic Photodynamic Therapy.

Controlling CRISPR/Cas9 gene editing at the spatiotemporal resolution level, especially for in vivo applications, remains a great challenge. Here, we developed a near-infrared (NIR) light-activated nanophotonic system (UCPP) for controlled CRISPR-Cas9 gene editing and synergistic photodynamic therapy (PDT). Lanthanide-doped upconversion nanoparticles are not only employed as carriers for intracellular plasmid delivery but also serve as the nanotransducers to convert NIR light (980 nm) into visible light with emission at 460 and 650 nm, which could result in simultaneous activation of gene editing and PDT processes, respectively.

Bidirectional associations among gallstone disease, non-alcoholic fatty liver disease, kidney stone disease.

Background: A body of evidence has suggested bidirectional relationships among gallstone disease (GSD), non-alcoholic fatty liver disease (NAFLD), and kidney stone disease (KSD). However, the results are inconsistent, and studies on this topic in China are relatively few. Our goal is to explore the bidirectional associations among these three diseases through a multicenter study, systematic review, and meta-analysis.

Noninvasive early identification of durable clinical benefit from immune checkpoint inhibition: a prospective multicenter study (NCT04566432).

Immune checkpoint inhibitors (ICIs) have changed the treatment landscape for patients with non-small cell lung cancer (NSCLC). In spite of durable responses in some patients, many patients develop early disease progression during the ICI treatment. Thus, early identification of patients with no durable benefit would facilitate the clinical decision for these patients.

Dose optimization of extended collimators in boron neutron capture therapy.

In this paper, we propose the design of extending collimators aimed at reducing the radiation dose received by patients with normal tissues and protecting organs at risk in Boron Neutron Capture Therapy (BNCT). Three types of extended collimators are studied: Type 1, which is a traditional design; Type 2, which is built upon Type 1 by incorporating additional polyethylene material containing lithium fluoride (PE(LiF)); Type 3, which adds lead (Pb) to Type 1. We evaluated the dose distribution characteristics of the above-extended collimators using Monte Carlo methods simulations under different configurations: in air, in a homogeneous phantom, and a humanoid phantom model.
