Tumor organoids have emerged as powerful tools for in vitro cancer research due to their ability to retain the structural and genetic characteristics of tumors. Nevertheless, the absence of a complete tumor microenvironment (TME) limits the broader application of organoid models in immunological studies. Given the critical role of immune cells in tumor initiation and progression, the co-culture model of organoids and peripheral blood mononuclear cells (PBMCs) may provide an effective platform for simulating the interactions between immune and tumor cells in vitro.

Currently, the 'gold standard' for diagnosis of Psoroptes ovis infections is detecting Psoroptes mites or eggs in skin scrapings under microscopy, but it is prone to be mis-diagnosed for detecting early infection of P. ovis. Hence, seeking a reliable diagnostic technique for detecting early-stage mite infections is extremely desirable.

Gut microbial metabolism of L-carnitine, which leads to the production of detrimental trimethylamine N-oxide (TMAO), offers a plausible link between red meat consumption and cardiovascular risks. Several microbial genes, including , the operon, and the recently identified gene cluster, have been implicated in the conversion of dietary L-carnitine into TMA(O). However, the key microbial genes and associated gut microbes involved in this pathway have not been fully explored.

Drug resistance and off-target toxicity of cisplatin (CDDP) pose significant challenges in effectively treating non-small cell lung cancer (NSCLC). Recently, chemodynamic therapy (CDT), an emerging reactive oxygen species (ROS)-mediated tumor-specific therapeutic modality, has shown great potential in sensitizing multidrug resistance tumor cells. Herein, a glutathione (GSH)-responsive Pt(IV) prodrug-based oxidative stress nanoamplifier (CuBSO@Pt) was developed for effective chemo/chemodynamic therapy to reverse CDDP resistance in NSCLC.

Department of Oral and Maxillofacial Surgery, Hospital of Stomatology, Jilin University, Changchun 130021, China.

Article Synopsis
  • Oral squamous cell carcinoma (OSCC) is particularly sensitive to ferroptosis, but traditional inducers have limitations.
  • This study created ultrasmall AuMn nanoclusters (AMNCs) wrapped in NK cell-derived exosomes (Exo-AMNCs) to enhance targeted treatment for OSCC.
  • The AMNCs produce reactive oxygen species to induce ferroptosis while being more biocompatible, and when combined with exosomes, they show effective imaging and therapeutic potential by regulating specific proteins involved in the disease.

Given the widespread use of partial hepatectomy for treating various liver pathologies, understanding the mechanisms of liver regeneration is vital for enhancing liver resection and transplantation therapies. Here, we demonstrate the critical role of the serine protease Hepsin in promoting hepatocyte hypertrophy and proliferation. Under steady-state conditions, liver-specific overexpression of Hepsin in adult wild-type mice triggers hepatocyte hypertrophy and proliferation, significantly increasing liver size.

Institute of Animal Culture Collection and Application, College of Animal Science and Technology, Yangzhou University, Yangzhou 225009, China. Electronic address:

Hexokinase 2 (HK2) plays a vital role in mitochondrial homeostasis; however, the molecular mechanisms underlying its involvement in high-concentrate diet-induced damage in the ruminal epithelium of dairy cows are poorly understood. This study aimed to explore the regulatory role of HK2 in mitochondrial function and responses to inflammation in the rumen of dairy cows fed a high-concentrate diet. Our results showed that, compared with a low-concentrate (LC) diet, feeding a high-concentrate (HC) diet increased oxidative stress and reduced relative antioxidant gene expression levels and enzyme activities in the ruminal epithelium.

Engineered Bacteria Manipulate Cysteine Metabolism to Boost Ferroptosis-Based Pancreatic Ductal Adenocarcinoma Therapy.

Adv Mater

December 2024

Engineering Research Center of Molecular & Neuroimaging, Ministry of Education, School of Life Science and Technology, Xidian University, Xi'an, 710126, P. R. China.

Cysteine metabolism is a key determinant of the defense against ferroptosis in pancreatic ductal adenocarcinoma (PDAC). Blocking cysteine metabolism may trigger potent ferroptosis in PDAC cells by generating lipid peroxides during tumor metabolic processes. However, current methods to limit cysteine availability fall short, failing to efficiently block cysteine metabolism due to inadequate tumor targeting and compensatory cysteine sources.

Laboratory Animal Center, Tianjin Medical University Cancer Institute and Hospital, National Clinical Research Center for Cancer, Tianjin, 300060, China.

At present, there is still a lack of effective treatment strategies for cancer metastasis and drug resistance, so finding effective biomarkers is particularly important. AnnexinA2 (ANXA2), a vital membrane protein, critically influences cancer progression, tumor invasion, and tumor microenvironment modulation. To assess the possible application of ANXA2 as a therapeutic target against cancer cell metastasis and drug resistance to chemotherapeutic drugs in the tumor microenvironment, we elucidated the functionality of ANXA2 in stromal cells, angiogenic vascular cells, and infiltrated immune cells that mediate metastasis and drug resistance, as well as its potential as a therapeutic target.

Guangdong Laboratory for Lingnan Modern Agriculture, College of Veterinary Medicine, South China Agricultural University, Guangzhou, 510642, China; State Key Laboratory for Animal Disease Control and Prevention, South China Agricultural University, Guangzhou, 510642, China. Electronic address:

Hepatitis E virus (HEV) is a major cause of acute and chronic hepatitis in humans. The HEV open reading frames (ORF1) encodes a large non-structural protein essential for viral replication, which contains several functional domains, including helicase and RNA-dependent RNA polymerase. A confusing aspect is that, while RNA viruses typically encode large polyproteins that rely on their enzymatic activity for processing into functional units, the processing of the ORF1 protein and the mechanisms involved remain unclear.
