Effects of ESPCS mode nursing on the surgical tolerance, gastrointestinal tract recovery and self‑management efficacy of patients with colon cancer.

Colon cancer is a common gastrointestinal malignant tumor. In addition to conventional treatment, thoughtful and comprehensive aftercare should be given to patients. The present study aimed to explore the effects of explain-simulate-practice-communication-support (ESPCS) model nursing on the surgical tolerance, gastrointestinal recovery and self-management efficacy of patients with colon cancer.

Effectiveness and Safety of Apatinib Plus Programmed Cell Death Protein 1 Blockades for Patients with Treatment-refractory Metastatic Colorectal Cancer: A Retrospective Exploratory Study.

This study aimed to investigate the efficacy and safety of apatinib plus programmed cell death protein 1 (PD-1) blockades for patients with metastatic colorectal cancer (CRC) who were refractory to the standard regimens. In this retrospective study, patients with metastatic CRC who received apatinib plus PD-1 blockades in clinical practice were included. The initial dosage of apatinib was 250 mg or 500 mg, and PD-1 blockades were comprised of camrelizumab, sintilimab and pembrolizumab.

Depleting glioblastoma cells of very long-chain acyl-CoA synthetase 3 (ACSVL3) produces metabolic alterations in non-lipid pathways.

Knockout (KO) of the fatty acid-activation enzyme very long-chain acyl-CoA synthetase 3 (ACSVL3; SLC27A3) in U87MG glioblastoma cells reduced their malignant growth properties both in vitro and in xenografts. These U87-KO glioma cells grew at a slower rate, became adherence-dependent, and were less invasive than parental U87 cells. U87-KO cells produced fewer, slower-growing subcutaneous and intracranial tumors when implanted in NOD-SCID mice.

Research Note: Identification of breeding-related candidate genes in Tianjin-monkey chickens by transcriptome analysis.

Tianjin-monkey Chicken is a locally bred dual-purpose naked neck poultry with high tolerance to heat stress and poor reproductive ability. We aim to explore breeding-related genes to promote its growth, reproduction, meat, and egg performances. In this study, purebred, crossbred neck-naked and crossbred neck-feathered Tianjin-monkey Chickens (male = 5 and female = 5 in each group) were sampled for transcriptome analysis.

Effect of cognitive behavioral stress management on anxiety, depression, and quality of life in colorectal cancer patients post tumor resection: a randomized, controlled study.

Objective: Cognitive behavioral stress management (CBSM) is a psychotherapy helping individuals develop adaptive behaviors, whose application in colorectal cancer (CRC) is rare. This randomized, controlled study intended to explore the effect of CBSM on anxiety, depression, and quality of life in CRC patients post tumor resection.

Methods: One hundred and sixty CRC patients who received tumor resection were randomized (1:1) to receive weekly CBSM or usual care (UC) for 10 weeks after discharge (120 min for each session).

VERY LONG-CHAIN ACYL-CoA SYNTHETASE-3 (ACSVL3) PROMOTES THE MALIGNANT GROWTH BEHAVIOR OF U87 GLIOMA CELLS VIA CHANGES IN CELL CYCLE WITHOUT AFFECTING APOPTOSIS.

Decreasing the expression of very long-chain acyl-CoA synthetase 3 (ACSVL3) in U87MG glioblastoma cells by either RNA interference or genomic knockout (KO) significantly decreased their growth rate in culture, as well as their ability to form rapidly growing tumors in mice. U87-KO cells grew at a 9-fold slower rate than U87MG cells. When injected subcutaneously in nude mice, the tumor initiation frequency of U87-KO cells was 70% of that of U87MG cells, and the average growth rate of tumors that did form was decreased by 9-fold.

Semi-Synthesis and Biological Evaluation of 25(-26-Acetoxy-3,5-Dihydroxycholest-6-One.

Previously, we identified a series of steroids (-) that showed potent anti-virus activities against respiratory syncytial virus (RSV), with IC values ranging from 3.23 to 0.19 µM.

Isocitrate dehydrogenase 1 mutation drives leukemogenesis by PDGFRA activation due to insulator disruption in acute myeloid leukemia (AML).

Acute myeloid leukemia (AML) is characterized by complex molecular alterations and driver mutations. Elderly patients show increased frequencies of IDH mutations with high chemoresistance and relapse rates despite recent therapeutic advances. Besides being associated with global promoter hypermethylation, IDH1 mutation facilitated changes in 3D DNA-conformation by CTCF-anchor methylation and upregulated oncogene expression in glioma, correlating with poor prognosis.

Targeting UDP-α-d-glucose 6-dehydrogenase alters the CNS tumor immune microenvironment and inhibits glioblastoma growth.

Glioblastoma (GBM, WHO grade IV glioma) is the most common and lethal malignant brain tumor in adults with a dismal prognosis. The extracellular matrix (ECM) supports GBM progression by promoting tumor cell proliferation, migration, and immune escape. Uridine diphosphate (UDP)-glucose 6-dehydrogenase (UGDH) is the rate-limiting enzyme that catalyzes the biosynthesis of glycosaminoglycans that are the principal component of the CNS ECM.

Fatty acid oxidation fuels glioblastoma radioresistance with CD47-mediated immune evasion.

Glioblastoma multiforme (GBM) remains the top challenge to radiotherapy with only 25% one-year survival after diagnosis. Here, we reveal that co-enhancement of mitochondrial fatty acid oxidation (FAO) enzymes (CPT1A, CPT2 and ACAD9) and immune checkpoint CD47 is dominant in recurrent GBM patients with poor prognosis. A glycolysis-to-FAO metabolic rewiring is associated with CD47 anti-phagocytosis in radioresistant GBM cells and regrown GBM after radiation in syngeneic mice.

ATRX loss promotes immunosuppressive mechanisms in IDH1 mutant glioma.

Background: ATRX inactivation occurs with IDH1R132H and p53 mutations in over 80% of Grades II/III astrocytomas. It is believed that ATRX loss contributes to oncogenesis by dysregulating epigenetic and telomere mechanisms but effects on anti-glioma immunity have not been explored. This paper examines how ATRX loss contributes to the malignant and immunosuppressive phenotypes of IDH1R132H/p53mut glioma cells and xenografts.

Monoallelic IDH1 R132H Mutation Mediates Glioma Cell Response to Anticancer Therapies via Induction of Senescence.

Heterozygous isocitrate dehydrogenase (IDH) R132H mutation (IDH1) is an early event during gliomagenesis. Clinically, patients with glioma carrying mutant IDH1 respond better to antitumor therapies. However, the mechanism by which IDH1 mutations contribute to gliomagenesis and therapeutic response remains elusive.

Mutant IDH1 promotes phagocytic function of microglia/macrophages in gliomas by downregulating ICAM1.

Tumor-associated microglia/macrophages (TAMs) are the main innate immune effector cells in malignant gliomas and have both pro- and anti-tumor functions. The plasticity of TAMs is partially dictated by oncogenic mutations in tumor cells. Heterozygous IDH1 mutation is a cancer driver gene prevalent in grade II/III gliomas, and IDH1 mutant gliomas have relatively favorable clinical outcomes.

EGFR Activates a TAZ-Driven Oncogenic Program in Glioblastoma.

Hyperactivated EGFR signaling is a driver of various human cancers, including glioblastoma (GBM). Effective EGFR-targeted therapies rely on knowledge of key signaling hubs that transfer and amplify EGFR signaling. Here we focus on the transcription factor TAZ, a potential signaling hub in the EGFR signaling network.

Frondoside A Inhibits an MYC-Driven Medulloblastoma Model Derived from Human-Induced Pluripotent Stem Cells.

Medulloblastoma (MB) is the most common malignant pediatric brain tumor. MYC-driven MBs, commonly found in the group 3 MB, are aggressive and metastatic with the worst prognosis. Modeling MYC-driven MB is the foundation of therapeutic development.

Highly efficient magnetic labelling allows MRI tracking of the homing of stem cell-derived extracellular vesicles following systemic delivery.

Human stem-cell-derived extracellular vesicles (EVs) are currently being investigated for cell-free therapy in regenerative medicine applications, but the lack of noninvasive imaging methods to track EV homing and uptake in injured tissues has limited the refinement and optimization of the approach. Here, we developed a new labelling strategy to prepare magnetic EVs (magneto-EVs) allowing sensitive yet specific MRI tracking of systemically injected therapeutic EVs. This new labelling strategy relies on the use of 'sticky' magnetic particles, namely superparamagnetic iron oxide (SPIO) nanoparticles coated with polyhistidine tags, to efficiently separate magneto-EVs from unencapsulated SPIO particles.

Distinct roles of programmed death ligand 1 alternative splicing isoforms in colorectal cancer.

Although anti-programmed death-1 (PD-1)/programmed death ligand 1 (PD-L1) immunotherapy has achieved great success in some cancers, most colorectal cancer (CRC) patients remain unresponsive. Therefore, further clarification of the underlying mechanisms is needed to improve the therapy. In this study, we explored the distinct functions of different PD-L1 alternative splicing isoforms in CRC.

Dual blockade of CD47 and HER2 eliminates radioresistant breast cancer cells.

Although the efficacy of cancer radiotherapy (RT) can be enhanced by targeted immunotherapy, the immunosuppressive factors induced by radiation on tumor cells remain to be identified. Here, we report that CD47-mediated anti-phagocytosis is concurrently upregulated with HER2 in radioresistant breast cancer (BC) cells and RT-treated mouse syngeneic BC. Co-expression of both receptors is more frequently detected in recurrent BC patients with poor prognosis.

Tenascin-C Function in Glioma: Immunomodulation and Beyond.

First identified in the 1980s, tenascin-C (TNC) is a multi-domain extracellular matrix glycoprotein abundantly expressed during the development of multicellular organisms. TNC level is undetectable in most adult tissues but rapidly and transiently induced by a handful of pro-inflammatory cytokines in a variety of pathological conditions including infection, inflammation, fibrosis, and wound healing. Persistent TNC expression is associated with chronic inflammation and many malignancies, including glioma.

ShRNA-based POLD2 expression knockdown sensitizes glioblastoma to DNA-Damaging therapeutics.

Glioblastoma (GBM) has limited therapeutic options. DNA repair mechanisms contribute GBM cells to escape therapies and re-establish tumor growth. Multiple studies have shown that POLD2 plays a critical role in DNA replication, DNA repair and genomic stability.

Suppressive effects of metformin on colorectal adenoma incidence and malignant progression.

Background: The linear progression from normal colonic epithelium to adenoma initiation, carcinoma transformation and metastasis is considered the classical model of colorectal cancer (CRC) development. Although metformin has been extensively reported to be negatively related to cancer incidence, the effect of metformin on CRC development remains unclear. We aimed to evaluate the role of metformin in the entire CRC linear progression.

Neutrophils homing into the retina trigger pathology in early age-related macular degeneration.

Age-related macular degeneration (AMD) is an expanding problem as longevity increases worldwide. While inflammation clearly contributes to vision loss in AMD, the mechanism remains controversial. Here we show that neutrophils are important in this inflammatory process.

Major depression but not minor to intermediate depression correlates with unfavorable prognosis in surgical colorectal cancer patients underwent adjuvant chemotherapy.

This study aimed to investigate the correlation of anxiety/depression with clinicopathological features, and the association of anxiety/depression degrees with overall survival (OS) in surgical colorectal cancer (CRC) patients. Three hundred and eighty-one surgical CRC patients were consecutively enrolled and underwent adjuvant chemotherapy accordingly. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale (HADS).
