We congratulate the authors for conducting this important research, which adds valuable information to the body of knowledge guiding our choice of the optimal treatment modality for large, benign colorectal polyps. However, we would like to address several points. First, readers should be aware that this study focuses on a highly selected group of large non-pedunculated colon polyps (LNPCPs) as only 20% of referred lesions during the study period of 4 years met the inclusion criteria, being flat lesions of 15–50 mm, without macronodule, depressed area or optical suspicion of submucosal invasive cancer (SMIC).

We previously reported that pancreas-specific Kras G12D and Gnas R201C co-expression in p48Cre; KrasLSL-G12D; Rosa26LSL-rtTA; Tg (TetO-GnasR201C) mice ( ‘Kras;Gnas ’ mice) caused development of cystic lesions recapitulating IPMNs. Objective We aim to unveil the consequences of mutant Gnas R201C expression on phenotype, transcriptomic profile and genomic dependencies. Design We performed multimodal transcriptional profiling (bulk RNA sequencing, single-cell RNA sequencing and spatial transcriptomics) in the ‘Kras;Gnas ’ autochthonous model and tumour-derived cell lines ( Kras;Gnas cells), where Gnas R201C expression is inducible. A genome-wide CRISPR/ Cas 9 screen was conducted to identify potential vulnerabilities in KrasG12D;GnasR201C co-expressing cells. Results Induction of Gnas R201C—and resulting G(s)alpha signalling—leads to the emergence of a gene signature of gastric (pyloric type) metaplasia in pancreatic neoplastic epithelial cells. CRISPR screening identified the synthetic essentiality of glycolysis-related genes Gpi1 and Slc2a1 in Kras G12D; Gnas R201C co-expressing cells. Real-time metabolic analyses in Kras;Gnas cells and autochthonous Kras;Gnas model confirmed enhanced glycolysis on Gnas R201C induction. Induction of Gnas R201C made Kras G12D expressing cells more dependent on glycolysis for their survival. Protein kinase A-dependent phosphorylation of the glycolytic intermediate enzyme 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) was a driver of increased glycolysis on Gnas R201C induction. Conclusion Multiple orthogonal approaches demonstrate that Kras G12D and Gnas R201C co-expression results in a gene signature of gastric pyloric metaplasia and glycolytic dependency during IPMN pathogenesis. The observed metabolic reprogramming may provide a potential target for therapeutics and interception of IPMNs. Data are available in a public, open access repository.

We aimed to characterise the long-term efficacy of small interfering RNA (siRNA) on hepatitis B surface antigen (HBsAg) suppression. Methods We prospectively followed up participants with CHB who received siRNA, either ARC-520 or JNJ-73763989 (JNJ-3989), in combination with nucleoside analogue (NUC) in our centre. Participants enrolled included 15 receiving 4 monthly injections of ARC-520, 38 receiving 3 injections of JNJ-3989 at 1, 2 or 4 weekly intervals and 5 receiving placebo in previous clinical trials. Serial blood sampling was performed according to the original protocols and on completion every 24 weeks until last follow-up (LFU) with mean duration of 52.5 months. Results Among the 53 NUC+siRNA-treated participants (mean age 46.8, baseline HBsAg 3.08 log, 83% previously on NUC, 34% hepatitis B e antigen+), the proportion of patients achieving HBsAg seroclearance or <100 IU/mL at LFU was 1.9% and 32.1%, respectively, compared with 0% and 0% for placebo. Among siRNA-recipients, 48.5% and 5.0% of those with HBsAg <100 IU/mL and >100 IU/mL at nadir or ≤24 weeks from last dose could maintain or achieve HBsAg <100 IU/mL at LFU, respectively. Compared with placebo recipients, siRNA-recipients demonstrated faster overall annual decline of HBsAg (0.08 vs 0.21 log IU/mL/year) contributed predominantly by changes in the first year. Age was negatively correlated with HBsAg reduction at LFU (r=−0.427, p=0.001).

The significance of TL1A:DR3 signalling in the pathogenesis of inflammatory bowel disease (IBD) is supported by several converging lines of evidence.To provide a comprehensive understanding of what is currently known regarding the TL1A/DR3 system in the context of IBD.TL1A and DR3 are expressed by cellular subsets with important roles for the initiation and maintenance of intestinal inflammation, serving as potent universal costimulators of effector immune responses, indicating their participation in the pathogenesis of IBD. Recent evidence also supports a homoeostatic role for TL1A:DR3 via regulation of Tregs and innate lymphoid cells. TL1A and DR3 are also expressed by stromal cells and may contribute to inflammation-induced or inflammation-independent intestinal fibrogenesis. Finally, discovery of genetic polymorphisms with functional consequences may allow for patient stratification, including differential responses to TL1A-targeted therapeutics.TL1A:DR3 signalling plays a central and multifaceted role in the immunological pathways that underlie intestinal inflammation, such as that observed in IBD. Such evidence provides the foundation for developing pharmaceutical approaches targeting this ligand-receptor pair in IBD.","PeriodicalId":12825,"journal":{"name":"Gut","volume":"16 1","pages":""},"PeriodicalIF":24.5,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142170852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We commend the authors for undertaking this study, which holds significant clinical implications. We also observed that Li et al 2 have validated the predictive value of inflamed class in two additional RNA-seq datasets from patients who received anti-PD1 therapy. However, the use of combination immunotherapy, which includes dual immune checkpoint inhibitors or is combined with anti-VEGF agents, has become a growing trend in HCC.3–6 Here, we first performed unsupervised clustering on the RNA-seq data from 289 patients enrolled in the GO30140 Ph1b and IMbrave150 PhIII trials who received a combination of anti-PD-L1 and anti-VEGF therapy7 (figure 1).

Chemotherapies are little effective and response to immune checkpoint inhibitors is limited. Therefore, new therapeutic strategies need to be identified. Objective We characterised the enzyme protein arginine-methyltransferase 5 (PRMT5) as a novel therapeutic target in CCA. Design We evaluated the expression of PRMT5, its functional partner MEP50 and methylthioadenosine phosphorylase (MTAP)—an enzyme that modulates the sensitivity of PRMT5 to pharmacological inhibitors—in human CCA tissues. PRMT5-targeting drugs, currently tested in clinical trials for other malignancies, were assessed in human CCA cell lines and organoids, as well as in two immunocompetent CCA mouse models. Transcriptomic, proteomic and functional analyses were performed to explore the underlying antitumoural mechanisms. Results PRMT5 and MEP50 proteins were correlatively overexpressed in most CCA tissues. MTAP was absent in 25% of intrahepatic CCA. PRMT5-targeting drugs markedly inhibited CCA cell proliferation, synergising with cisplatin and gemcitabine and hindered the growth of cholangiocarcinoma organoids. PRMT5 inhibition blunted the expression of oncogenic genes involved in chromatin remodelling and DNA repair, consistently inducing the formation of RNA loops and promoting DNA damage. Treatment with PRMT5-targeting drugs significantly restrained the growth of experimental CCA without adverse effects and concomitantly induced the recruitment of CD4 and CD8 T cells to shrinking tumourous lesions. Conclusion PRMT5 and MEP50 are frequently upregulated in human CCA, and PRMT5-targeting drugs have significant antitumoural efficacy in clinically relevant CCA models. Our findings support the evaluation of PRMT5 inhibitors in clinical trials, including their combination with cytotoxic and immune therapies.

While the AI-driven prediction performed relatively well, the authors highlighted potential shortcomings that can limit its value in clinical practice. Defining the pathogenic potential of CPA1 variants detected in pancreatitis cases can be challenging because the mechanistic basis of disease risk is unrelated to loss of CPA1 function and seems to be determined by mutation-induced misfolding and the ensuing endoplasmic reticulum (ER) stress.3–5 Recently, we used transiently transfected HEK 293T cells to measure the secretion efficiency and induction of BiP mRNA expression, a marker of ER stress, for 50 missense CPA1 variants from pancreatitis cases and healthy controls.6 We found that the best predictor of pathogenicity was loss of secretion (<10% of wild type) irrespective of BiP levels.
