For patients with advanced non-small cell lung cancer (NSCLC) that have epidermal growth factor receptor () mutations, EGFR tyrosine kinase inhibitors (TKIs) are the standard treatment and have significant clinical benefits. Third-generation TKIs, such as osimertinib, almonertinib and furmonertinib, are effective for the treatment of NSCLC that is EGFR-sensitizing mutation-positive and T790M-positive. Despite the efficacy of third-generation TKIs, patients inevitably develop resistance and the resistance mechanisms are heterogeneous.

Hepatocellular carcinoma (HCC) is among the most common malignant liver tumors. Despite progress in anticancer drugs and surgical approaches, early detection of HCC remains challenging, often leading to late-stage diagnosis where rapid disease progression precludes surgical intervention, leaving chemotherapy as the only option. However, the systemic toxicity, low bioavailability, and significant adverse effects of chemotherapy drugs often lead to resistance, rendering treatments ineffective for many patients.

Tumor-derived extracellular vesicle proteins as new biomarkers and targets in precision oncology.

J Mol Med (Berl)

August 2024

Department of Oncology, Shenzhen Key Laboratory of Gastrointestinal Cancer Translational Research, Cancer Institute, Peking University Shenzhen Hospital, Shenzhen-Peking University-Hong Kong University of Science and Technology Medical Center, Shenzhen, China.

Extracellular vesicles (EVs) are important carriers of signaling molecules, such as nucleic acids, proteins, and lipids, and have become a focus of increasing interest due to their numerous physiological and pathological functions. For a long time, most studies on EV components focused on noncoding RNAs; however, in recent years, extracellular vesicle proteins (EVPs) have been found to play important roles in diagnosis, treatment, and drug resistance and thus have been considered favorable biomarkers and therapeutic targets for various tumors. In this review, we describe the general protocols of research on EVPs and summarize their multifaceted roles in precision medicine applications, including cancer diagnosis, dynamic monitoring of therapeutic efficacy, drug resistance research, tumor microenvironment interaction research, and anticancer drug delivery.

Fully grown oocytes have the natural ability to transform 2 terminally differentiated gametes into a totipotent zygote representing the acquisition of totipotency. This process wholly depends on maternal-effect factors (MFs). MFs stored in the eggs are therefore likely to be able to induce cellular reprogramming to a totipotency state.

Article Synopsis
  • * LUAD can be categorized into two metabolic phenotypes: redox and non-redox, with significant differences in mutation prevalence and immune cell response; redox LUAD primarily features mutations in KEAP1, STK11, NRF2, and SMARCA4.
  • * Patients with the redox phenotype show poorer response rates, progression-free survival, and overall survival when treated with ICIs, largely due to a reduction in tissue-resident memory CD8+ T cells.

Obesity has a significant impact on endocrine function, which leads to metabolic diseases including diabetes, insulin resistance, and other complications associated with obesity. Development of effective and safe anti-obesity drugs is imperative and necessary. Equisetin (EQST), a tetramate-containing marine fungal product, was reported to inhibit bacterial fatty acid synthesis and affect mitochondrial metabolism.

Antisense oligonucleotide (ASO) is a novel therapeutic platform for targeted cancer therapy. Previously, we have demonstrated that miR-146b-5p plays an important role in colorectal cancer progression. However, a safe and effective strategy for delivery of an ASO to its targeted RNA remains as a major hurdle in translational advances.

Sulindac selectively induces autophagic apoptosis of GABAergic neurons and alters motor behaviour in zebrafish.

Nat Commun

September 2023

Division of Cell, Developmental and Integrative Biology, School of Medicine, South China University of Technology, Guangzhou, 510006, China.

Nonsteroidal anti-inflammatory drugs compose one of the most widely used classes of medications, but the risks for early development remain controversial, especially in the nervous system. Here, we utilized zebrafish larvae to assess the potentially toxic effects of nonsteroidal anti-inflammatory drugs and found that sulindac can selectively induce apoptosis of GABAergic neurons in the brains of zebrafish larvae brains. Zebrafish larvae exhibit hyperactive behaviour after sulindac exposure.

The pathogenesis of Parkinson's disease (PD) remains unclear. Among the pathological manifestations is the progressive degeneration of the nigrostriatal dopaminergic pathway, leading to massive loss of neurons in the substantia nigra pars compacta and dopamine (DA) depletion. Therefore, the current drug treatment is primarily based on DA supplementation and delaying the progression of the disease.

Article Synopsis
  • Bacterial vaginosis (BV) is a common infection linked to a decrease in beneficial lactobacilli in the vaginal microbiome, and this study evaluates the effectiveness of two probiotics, TM13 and LG55, alongside metronidazole (MET) in treating Chinese women with BV.
  • A controlled trial with 67 participants showed that while probiotics did not significantly improve BV cure rates compared to the control group, they were more effective in restoring vaginal health post-treatment, as evidenced by better Nugent Scores for vaginal health.
  • The probiotics improved intestinal microbiome diversity but weren't present in the vaginal microbiome, indicating that their benefits mainly occurred through the gut, and higher baseline levels of certain bacteria were linked to treatment failure.

ANO1-Mediated Inhibition of Cancer Ferroptosis Confers Immunotherapeutic Resistance through Recruiting Cancer-Associated Fibroblasts.

Department of Gastrointestinal Oncology, Key Laboratory of Carcinogenesis and Translational Research (Ministry of Education/Beijing), Peking University Cancer Hospital & Institute, Beijing, 100142, P. R. China.

The application of immunotherapy in gastrointestinal (GI) cancers remains challenging because of the limited response rate and emerging therapeutic resistance. Combining clinical cohorts, multi-omics study, and functional/molecular experiments, it is found that ANO1 amplification or high-expression predicts poor outcomes and resistance to immunotherapy for GI cancer patients. Knocking-down or inhibiting ANO1 suppresses the growth/metastasis/invasion of multiple GI cancer cell lines, cell-derived xenograft, and patient-derived xenograft models.

Low-temperature plasma-activated medium enhances the chemosensitivity of colorectal cancer cells by improving hypoxia.

Department of Oncology, Shenzhen Key Laboratory of Gastrointestinal Cancer Translational Research, Cancer Institute, Peking University Shenzhen Hospital, Shenzhen-Peking University-Hong Kong University of Science and Technology Medical Center Shenzhen 518036, Guangdong, China.

Studies have demonstrated that the tumour microenvironment is hypoxia and that hypoxia can induce hypoxia inducible factor-1α (HIF-1α) expression and mediate tumour chemoresistance, which leads to a very poor prognosis for cancer patients. In this study, an economical and practical HIF-1α inhibitor, plasma-activated medium (PAM), was prepared, and its role in colorectal cancer (CRC) was investigated and . We found that HIF-1α expression significantly increased under hypoxia in CRC cells followed by decreased chemosensitivity to oxaliplatin (OXA).

Electronic address:

Metaphocytes are tissue-resident macrophage (TRM)/dendritic cell (DC)-like cells of non-hematopoietic origin in zebrafish barrier tissues. One remarkable property of metaphocytes is their ability to capture soluble antigens from the external environment via transepithelial protrusions, a unique function manifested by specialized subpopulations of the TRMs/DCs in mammal barrier tissues. Yet, how metaphocytes acquire myeloid-like cell properties from non-hematopoietic precursors and how they regulate barrier immunity remains unknown.
