A case report: spleen Epstein-Barr virus-positive inflammatory follicular dendritic cell sarcoma.

Background: Epstein-Barr virus-positive (EBV) inflammatory follicular dendritic cell sarcoma (IFDCS) is a rare stroma-derived neoplasm of lymphoid tissues. It typically involves the spleen and liver, and is often associated with the presence of EBV. Because of its nonspecific clinical and imaging findings, making a correct diagnosis at the time of initial diagnosis is challenging.

AMPK: an energy sensor for Non-small cell lung cancer progression and treatment.

Lung cancer (LC) is the leading cause of cancer-related morbidity and mortality in China, with non-small cell lung cancer (NSCLC) accounting for 85% of the overall lung cancer cases. AMP-activated protein kinase (AMPK) is a key regulator of energy balance and homeostasis, and its dysregulation is a common feature in various malignancies, particularly in NSCLC with mutations in Liver kinase B1 (LKB1). Studies have shown that the AMPK signalling pathway has a dual role in NSCLC progression, both inhibiting and promoting the progression of malignant tumours.

PIKFYVE deficiency induces vacuole-like cataract via perturbing late endosome homeostasis.

Phosphoinositide kinase, FYVE-type zinc finger containing (PIKFYVE) was recently identified as a causative gene for cataract. Pikfyve phosphatidylinositol phosphate kinase domain-deficient (pikfyve) zebrafish lens and PIKFYVE-inhibited human lens epithelial cells developed vacuoles, colocalized with late endosome marker RAB7. In this study, the pikfyvezebrafish with vacuole-like cataract underwent transcriptomic and proteomic analyses to explore the underlying mechanisms of vacuole formation.

The modulation of calcium and chloride channels induces cardiomyocytes from human pluripotent stem cells.

Ion channels play a crucial role in cardiac functions, and their activities exhibit dynamic changes during heart development. However, the precise function of ion channels in human heart development remains elusive. In this study, we utilized human embryonic stem cells (hESCs) as a model to mimic the process of human embryonic heart development.

High-risk breast lesions: a combined intratumoral and peritumoral radiomics nomogram model to predict pathologic upgrade and reduce unnecessary surgical excision.

Objective: This study aimed to develop a nomogram that combines intratumoral and peritumoral radiomics based on multi-parametric MRI for predicting the postoperative pathological upgrade of high-risk breast lesions and sparing unnecessary surgeries.

Methods: In this retrospective study, 138 patients with high-risk breast lesions (January 1, 2019, to January 1, 2023) were randomly divided into a training set (n=96) and a validation set (n=42) at a 7:3 ratio. The best-performing MRI sequence for intratumoral radiomics was selected to develop individual and combined radiomics scores (Rad-Scores).

Autophagy Regulates Ferroptosis-Mediated Diabetic Liver Injury by Modulating the Degradation of ACSL4.

Diabetic liver injury is a serious complication due to the lack of effective treatments and the unclear pathogenesis. Ferroptosis, a form of cell death involving reactive oxygen species (ROS)-dependent lipid peroxidation (LPO), is closely linked to autophagy and diabetic complications. Therefore, this study is aimed at investigating the role of autophagy in regulating ferroptosis by modulating the degradation of acyl-CoA synthetase long-chain family member 4 (ACSL4) in diabetic hepatocytes and its potential impact on diabetic liver injury.

Astragalus Polysaccharide Mitigates Rhabdomyolysis-Induced Acute Kidney Injury via Inhibition of M1 Macrophage Polarization and the cGAS-STING Pathway.

Purpose: This study aimed to examine the impact of APS on acute kidney injury induced by rhabdomyolysis (RIAKI), exploring its association with macrophage M1 polarization and elucidating the underlying mechanisms.

Methods: C57BL/6J mice were randomly assigned to one of three groups: a normal control group, a RIAKI model group, and an APS treatment group. Techniques such as flow cytometry and immunofluorescence were employed to demonstrate that APS can inhibit the transition of renal macrophages to the M1 phenotype in RIAKI.

p62 Binding to Protein Kinase C Regulates HIV-1 gp120 V3 Loop Induced Microglial Inflammation.

The main pathogenic mechanism of HIV-associated neurocognitive disorders (HAND) is neuronal apoptosis induced by inflammatory mediators, in which microglial inflammation plays a crucial role. However, the exact pathogenic mechanism remains unclear. Previous studies have shown that the HIV-1 gp120 V3 loop can trigger inflammation in CHME-5 microglia.

PAGE-based transfer learning from single-cell to bulk sequencing enhances model generalization for sepsis diagnosis.

Sepsis, caused by infections, sparks a dangerous bodily response. The transcriptional expression patterns of host responses aid in the diagnosis of sepsis, but the challenge lies in their limited generalization capabilities. To facilitate sepsis diagnosis, we present an updated version of single-cell Pair-wise Analysis of Gene Expression (scPAGE) using transfer learning method, scPAGE2, dedicated to data fusion between single-cell and bulk transcriptome.

V-ATPase in cancer: mechanistic insights and therapeutic potentials.

Vacuolar-type H+-ATPase (V-ATPase) is a crucial proton pump that plays an essential role in maintaining intracellular pH homeostasis and a variety of physiological processes. This review provides an in-depth exploration of the structural components, functional mechanisms, and regulatory modes of V-ATPase in cancer cells. Comprising two main domains, V and V, V-ATPase drives the proton pump through ATP hydrolysis, sustaining the pH balance within the cell and organelles.

Immunotherapy for locally advanced and metastatic basal cell carcinoma: a narrative review.

Background And Objective: Basal cell carcinoma (BCC) is the most common malignancy of humankind, characterized by its low propensity for metastasis and its high recurrence rate. Surgical intervention is the predominant therapeutic approach. However, for cases of locally advanced BCC (laBCC) and metastatic BCC (mBCC), systematic therapy may be the first option.

Synergistic enhancement of low-dose radiation therapy via cuproptosis and metabolic reprogramming for radiosensitization in in situ hepatocellular carcinoma.

Background: Radiotherapy (RT) is a primary clinical approach for cancer treatment, but its efficacy is often hindered by various challenges, especially radiation resistance, which greatly compromises the therapeutic effectiveness of RT. Mitochondria, central to cellular energy metabolism and regulation of cell death, play a critical role in mechanisms of radioresistance. In this context, cuproptosis, a novel copper-induced mitochondria-respiratory-dependent cell death pathway, offers a promising avenue for radiosensitization.

Hepatocyte HIF-2α aggravates NAFLD by inducing ferroptosis through increasing extracellular iron.

Recent research has illuminated the pivotal role of the hypoxia-inducible factor-2α (HIF-2α)/peroxisome proliferator-activated receptor alpha (PPARα) pathway in the progression of nonalcoholic fatty liver disease (NAFLD). Meanwhile, it has been reported that HIF-2α is involved in iron regulation, and that aberrant iron distribution leads to liver lipogenesis. Therefore, we hypothesize that HIF-2α exacerbates fatty liver by affecting iron distribution.

Unraveling the gut: the pivotal role of intestinal mechanisms in Kawasaki disease pathogenesis.

Kawasaki disease (KD), an acute systemic vasculitis that primarily affects children under 5 years of age, is the leading cause of acquired heart disease in this age group. Recent studies propose a novel perspective on KD's etiology, emphasizing the gastrointestinal (GI) tract, particularly the role of gut permeability. This review delves into how disruptions in gut barrier function trigger systemic inflammatory responses, exacerbate vascular inflammation, and contribute to coronary artery aneurysms.

Biodegradable silk fibroin membranes for potential localized treatment of melanoma: optimized preparation andstudy.

As a lethal skin cancer, melanoma is highly aggressive and metastatic with high recurrence rates and the common therapy is surgical resection followed by chemotherapy. To minimize the side effects of chemotherapeutic drugs and prevent tumor recurrence, localized therapy is a more suitable treatment method. Here, a fully biodegradable silk fibroin (SF) membrane loaded with the therapeutic drug doxorubicin (Dox) is fabricated for potential localized chemotherapy of melanoma.
