Objective:This study aims to evaluate the quality and explore the preliminary clinical applications of a domestically developed hepatitis D virus nucleic acid quantification reagent (abbreviated as"domestic HDV RNA reagent").Methods:The sensitivity and accuracy of the reagent were evaluated in accordance with the WHO HDV RNA international standard, employing the Bio-Rad CFX Opus 96 real-time fluorescence quantitative PCR analysis system. Serial dilutions of pseudo-viruses or cell culture-derived virus were used to determine the linear range of the domestic HDV RNA reagent. Specificity was assessed using positive samples of HAV, HBV, HCV infection, and HEV national reference materials. Precision was evaluated with samples at both high and low concentrations. In a comparative analysis, 30 HDV IgG positive samples were tested using both the domestic HDV RNA reagent and the RoboGene HDV RNA kit based on the ABI 7500 FAST DX system. The Pearson correlation coefficient (r) was used to examine the correlation between the two reagents.Results:The domestic HDV RNA reagent demonstrated a high sensitivity of up to 6 IU/ml, consistent with that of the comparator reagent. The calibration curve for WHO HDV RNA standards had a slope of -3.286, with an amplification efficiency of 101.6%. The linear detection range spanned from 10 to 10 8 IU/ml for eight HDV genotypes. The domestic HDV RNA reagent exhibited exceptional specificity, without cross-reactivity observed with HAV, HBV, HCV, or HEV. Accuracy assessments at five concentration levels met the required standards, with intra-assay precision coefficient of variation ( CV) ranging from 1.20% to 4.20%, and inter-assay precision CV from 1.20% to 7.90%. The detection results for HDV IgG positive samples were highly correlated with the comparator reagent ( r=0.984, P<0.001), achieving a diagnostic accuracy of 100% compared to sequencing results. Conclusion:In this study, the domestic HDV RNA reagent possesses excellent specificity, accuracy, precision, and a broad linear range, attaining a sensitivity level on par with international reagents of the same type.

Background::Liver cancer is largely resistant to chemotherapy. This study aimed to identify the effective chemotherapeutics for β-catenin-activated liver cancer which is caused by gain-of-function mutation of catenin beta 1 ( CTNNB1), the most frequently altered proto-oncogene in hepatic neoplasms. Methods::Constitutive β-catenin-activated mouse embryonic fibroblasts (MEFs) were established by deleting exon 3 ( β-cateninΔ(ex3)/+ ), the most common mutation site in CTNNB1 gene. A screening of 12 widely used chemotherapy drugs was conducted for the ones that selectively inhibited β-cateninΔ(ex3)/+ but not for wild-type MEFs. Untargeted metabolomics was carried out to examine the alterations of metabolites in nucleotide synthesis. The efficacy and selectivity of methotrexate (MTX) on β-catenin-activated human liver cancer cells were determined in vitro. Immuno-deficient nude mice subcutaneously inoculated with β-catenin wild-type or mutant liver cancer cells and hepatitis B virus ( HBV); β-cateninlox(ex3)/+ mice were used, respectively, to evaluate the efficacy of MTX in the treatment of β-catenin mutant liver cancer. Results::MTX was identified and validated as a preferential agent against the proliferation and tumor formation of β-catenin-activated cells. Boosted nucleotide synthesis was the major metabolic aberration in β-catenin-active cells, and this alteration was also the target of MTX. Moreover, MTX abrogated hepatocarcinogenesis of HBV; β-cateninlox(ex3)/+ mice, which stimulated concurrent Ctnnb1-activated mutation and HBV infection in liver cancer. Conclusion::MTX is a promising chemotherapeutic agent for β-catenin hyperactive liver cancer. Since repurposing MTX has the advantages of lower risk, shorter timelines, and less investment in drug discovery and development, a clinical trial is warranted to test its efficacy in the treatment of β-catenin mutant liver cancer.

Objective:To investigate the value of the extrahepatic bile duct and main pancreatic duct segment patterns on magnetic resonance cholangiopancreatography (MRCP) for differentiating the periampullary carcinoma (PAC).Methods:The clinicopathologic data of 125 patients with PAC who were admitted to Wuxi No.2 People’s Hospital from June 2013 to December 2021 were retrospectively analyzed, including 72 males and 53 females, aged (64.9±8.6) years. According to its anatomy, the extrahepatic bile duct (B) was divided into suprapancreatic and intrapancreatic (including ampullary) segments, and the main pancreatic duct (P) was divided into tail-body and head segments. MRCP patterns: i. the extrahepatic bile duct or main pancreatic duct visible without dilatation, ii. cutoff of the distal extrahepatic bile duct or main pancreatic duct with upstream dilatation, iii. cutoff of the intrapancreatic or head segment with upstream dilatation and remnant intrapancreatic or head segments invisible, iv. cutoff of the intrapancreatic or head segment with upstream dilatation and nondilated remnant intrapancreatic or head segments, were represented as 0, 1, 2, and 3, respectively. Segment patterns of B1/P0+ B1/P1, B0/P2+ B0/P3+ B2/P2+ B2/P3+ B3/P3, B3/P0, and B0/P0+ B2/P0 on MRCP were compared in PAC patients.Results:Of the 125 patients, there were 57 (45.6%) with pancreatic head carcinoma, 36 (28.8%) with ampullary carcinoma, 20 (16.0%) with distal cholangiocarcinoma, and 12 (9.6%) with periampullary duodenal carcinoma. Segment patterns of B0/P2+ B0/P3+ B2/P2+ B2/P3+ B3/P3 were found in 52 patients with pancreatic head carcinoma (91.2%, 52/57), with a significant difference between PAC (χ 2=110.66, P<0.001). Segment patterns of B1/P0+ B1/P1were found in 36 patients with ampullary carcinoma (100.0%, 36/36), fallowed by 11 (91.7%, 11/12) with periampullary duodenal carcinoma, with a significant difference between PAC (χ 2=129.95, P<0.001). Segment pattern of B3/P0 presented in 16 patients with distal cholangiocarcinoma (80.0%, 16/20), with a significant difference between PAC (χ 2=62.45, P<0.001). The segment patterns of B0/P0+ B2/P0 were only seen in 3 of 57(5.3%) patients with pancreatic head carcinoma. Conclusion:On MRCP, cutoff of the head segment with upstream dilatation and remnant head segment invisible or nondilated indicates the pancreatic head carcinoma. Cutoff of the intrapancreatic segment with upstream dilatation, remnant intrapancreatic segment visible, and main pancreatic duct nondilated, indicates the distal cholangiocarcinoma. And cutoff of the distal extrahepatic segment with upstream dilatation and main pancreatic duct dilatation or not, indicates the ampullary or periampullary duodenal carcinoma.

In contrast to the well-established genomic 5-methylcytosine (5mC), the existence of N6-methyladenine (6 mA) in eukaryotic genomes was discovered only recently. Initial studies found that it was actively regulated in cancer cells, suggesting its involvement in the process of carcinogenesis. However, the contribution of 6 mA in tongue squamous cell carcinoma (TSCC) still remains uncharacterized. In this study, a pan-cancer type analysis was first performed, which revealed enhanced 6 mA metabolism in diverse cancer types. The study was then focused on the regulation of 6 mA metabolism, as well as its effects on TSCC cells. To these aspects, genome 6 mA level was found greatly increased in TSCC tissues and cultured cells. By knocking down 6 mA methylases N6AMT1 and METTL4, the level of genomic 6 mA was decreased in TSCC cells. This led to suppressed colony formation and cell migration. By contrast, knockdown of 6 mA demethylase ALKBH1 resulted in an increased 6 mA level, enhanced colony formation, and cell migration. Further study suggested that regulation of the NF-κB pathway might contribute to the enhanced migration of TSCC cells. Therefore, in the case of TSCC, we have shown that genomic 6 mA modification is involved in the proliferation and migration of cancer cells.
