        Prognostic Value of TP53 Mutation for Transcatheter Arterial Chemoembolization Failure/Refractoriness in HBV-Related Advanced Hepatocellular Carcinoma

        Miao Xue,Yanqin Wu,Wenzhe Fan,Jian Guo,Jialiang Wei,Hongyu Wang,Jizhou Tan,Yu Wang,Wang Yao,Yue Zhao,Jiaping Li 대한암학회 2020 Cancer Research and Treatment Vol.52 No.3

        Purpose This study aimed to investigate the clinicopathologic features and mutational landscape of patients with hepatitis B virus (HBV)–related advanced hepatocellular carcinomas (HCC) undergoing transcatheter arterial chemoembolization (TACE). Materials and Methods From January 2017 to December 2018, 38 patients newly diagnosed with HBV-related advanced HCC were enrolled in the final analysis. Their pathological tissues and corresponding blood samples before TACE treatment were collected for whole-exome sequencing. Response to TACE was evaluated at 1-3 months after two consecutive use of TACE. Predictive factors were analyzed by univariate and multivariate analyses in a bivariate Logistic regression model. Enrichment of related pathways of all driver genes were acquired using the gene set enrichment analysis (GSEA). Results Among 38 patients, 23 (60.5%) exhibited TACE failure/refractoriness. Patients with TACE failure/refractoriness showed higher frequency of TP53 mutation than their counterparts (p=0.020). Univariate and multivariate analyses showed that only vascular invasion and TP53mutation were significantly correlated with TACE failure/refractoriness in HBV-related advanced HCC. Of the 16 patients without vascular invasion, eight (50.0%) had TP53 mutations, and TP53mutation was associated with TACE failure/refractoriness (p=0.041). Moreover, GSEA showed that mitogen-activated protein kinase and apoptosis pathways induced by TP53 mutation were possibly associated with TACE failure/refractoriness. Conclusion Our study suggested that TP53 mutation was independently related with TACE efficacy, which may work via mitogen-activated protein kinase and apoptosis pathways. These findings may provide evidence to help distinguish patients who will particularly benefit from TACE from those who require more personalized therapeutic regimens and rigorous surveillance in HBV-related advanced HCC.

        RNA-seq for comparative transcript profiling in leaves of strawberry seedlings under salinity stress

        Zhang Rui,Du Qiuli,Zhao Wenzhe,Yang Long,Li Dong-mei,Chen Xiude,Xiao Wei,Fu Xiling,Yang Chao,Li Ling 한국식물생명공학회 2023 Plant biotechnology reports Vol.17 No.1

        As a major economic crop, strawberry (Fragaria × ananassa Duch.) has been widely planted in the world because of their adaptability and high economic efficiency. In the process of strawberry production, the traditional techniques of furrow irrigation, irrigating irrigation and water and fertilizer management are still relatively common, resulting in secondary salinization of the soil and an imbalance of nutrient ratio, resulting in a decrease in strawberry yield and quality. A total of 2334, 2718 differentially expressed genes (DEGs) were identified in the 3-day, 6-day salt-treated leaf tissues compared with the controls, respectively. Based on the analysis of DEG function annotation and enrichment, a pattern of strawberry leaves response to NaCl stress was proposed. The processes related to plant hormone signal and lipid metabolism pathway were noted in the response of strawberry leaves to NaCl. Our transcriptome data provides valuable insights into genes involved in the growing process of strawberry seedlings under salt stress, and may help in developing seedlings with enhanced responses to salt stress in the years to come.
