RESUMO

Purpose: Anlotinib, a novel multi-target tyrosine kinase inhibitor, has shown encouraging antitumor effects in advanced hepatocellular carcinoma (HCC). This study evaluated the effectiveness and safety of anlotinib with or without programmed death-1 (PD-1) blockades for patients with advanced primary HCC in a real-world setting in China. Patients and Methods: Between July 2019 and May 2021, 27 patients with advanced primary HCC who received at least 2 cycles of anlotinib were included in this retrospective study. Primary endpoint was objective response rate (ORR). Secondary endpoints were disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results: Of the 27 patients, ORR and DCR were 25.93% and 74.07%, respectively. The median follow-up time was 6.27 months (range: 1.30-17.40) with a median PFS and OS of 3.29 months (95% CI: 1.31-15.47) and 6.21 months (95% CI: 2.23-15.87), respectively. A total of 14 patients received anlotinib and PD-1 blockade combination therapy, and 13 received anlotinib monotherapy. No significant differences were observed in ORR (28.57 vs 23.08%), DCR (71.43 vs 76.92%), PFS (3.38 [95% CI: 2.66-13.14] vs 11.86 months [95% CI: 4.27-15.93]) and OS (4.90 [95% CI: 2.56-13.60] vs 11.04 months [95% CI: 1.31-17.18]) between the two groups (all p>0.05). Treatment-related AEs were reported in 88.89% of patients. Grade 3 AE was bleeding, which occurred in 3 patients (11.11%). Conclusion: Anlotinib yielded a promising efficacy and manageable safety in patients with advanced primary HCC irrespective of whether patients received PD-1 blockades, indicating that anlotinib might be a promising treatment option for this patient population.

RESUMO

As a highly important fish virus, nervous necrosis virus (NNV) has caused severe economic losses to the aquaculture industry worldwide. Autophagy, an evolutionarily conserved intracellular degradation process, is involved in the pathogenesis of several viruses. Although NNV can induce autophagy to facilitate infection in grouper fish spleen cells, how it initiates and mediates autophagy pathways during the initial stage of infection is still unclear. Here, we found that red-spotted grouper NNV (RGNNV) induced autophagosome formation in two fish cell lines at 1.5 and 3 h post infection, indicating that autophagy is activated upon entry of RGNNV. Moreover, autophagic detection showed that RGNNV entry induced incomplete autophagy by impairing the fusion of autophagosomes with lysosomes. Further investigation revealed that binding of the RGNNV capsid protein (CP) to the Lateolabrax japonicus heat shock protein HSP90ab1 (LjHSP90ab1), a cell surface receptor of RGNNV, contributed to RGNNV invasion-induced autophagy. Finally, we found that CP blocked the interaction of L. japonicus protein kinase B (AKT) with LjHSP90ab1 by competitively binding the NM domain of LjHSP90ab1 to inhibit the AKT-mechanistic target of the rapamycin (MTOR) pathway. This study provides novel insight into the relationship between NNV receptors and autophagy, which may help clarify the pathogenesis of NNV.

RESUMO

Glucosinolates, an important class of secondary metabolites in cruciferous vegetables, play a crucial role in protecting plants from stress-related damage. The mechanism of glucosinolate synthesis under short-term high temperature stress has not been sufficiently studied. In this work, we investigated the changes in transcription factors, synthetic genes, and related metabolites involved in glucosinolate synthesis by pakchoi seedlings under short-term high temperature stress (40 °C for 8 h). Short-term high temperature stress inhibited the primary sulfur assimilation and the contents of methionine, cysteine and glutathione. The contents of aliphatic and indolic glucosinolates were increased by short-term high temperature stress, whereas the content of 4-methoxy-glucobrassicin increased significantly. During the stress period, the transcript level of glucosinolate related MYB transcription factors had been basically significantly up-regulated, whereas the transcript level of aliphatic and indolic glucosinolate synthetic genes were predominantly up-regulated and down-regulated respectively. In the early recovery period, primary sulfur assimilation up-regulated rapidly, and decreased during the late recovery process. The glucosinolate content and synthesis gene expression act similar to the primary sulfur assimilation, a short up-regulated in early recovery, then all go down at 40 and 48 h after short-term high temperature treatment.

RESUMO

Lung cancer is the world's highest morbidity and mortality of malignant tumors, with lung adenocarcinoma (LUAD) as a major subtype. The competitive endogenous RNA (ceRNA) regulative network provides opportunities to understand the relationships among different molecules, as well as the regulative mechanisms among them in order to investigate the whole transcriptome landscape in cancer pathology. We designed this work to explore the role of a key oncogene, MYC, in the pathogenesis of LUAD, and this study aims to identify important long noncoding RNA (lncRNA)-microRNA (miRNA)- transcription factor (TF) interactions in non-small cell lung cancer (NSCLC) using a bioinformatics analysis. The Cancer Genome Atlas (TCGA) database, containing mRNA expression data of NSCLC, was used to determine the deferentially expressed genes (DEGs), and the ceRNA network was composed of WT1-AS, miR-206, and nicotinamide phosphoribosyltransferase (NAMPT) bashing on the MYC expression level. The Kaplan-Meier univariate survival analysis showed that these components may be closely related prognostic biomarkers and will become new ideas for NSCLC treatment. Moreover, the high expression of WT1-AS and NAMPT and low expression of miR-206 were associated with a shortened survival in NSCLC patients, which provided a survival advantage. In summary, the current study constructing a ceRNA-based WT1-AS/miR-206/NAMPT axis might be a novel important prognostic factor associated with the diagnosis and prognosis of LUAD.

RESUMO

Hepatocellular carcinoma (HCC) is one of the deadliest malignant tumors that are harmful to human health. Increasing evidence has underscored the critical role of the competitive endogenous RNA (ceRNA) regulatory networks among various human cancers. However, the complexity and behavior characteristics of the ceRNA network in HCC were still unclear. In this study, we aimed to clarify a phosphatase and tensin homolog (PTEN)-related ceRNA regulatory network and identify potential prognostic markers associated with HCC. The expression profiles of three RNAs (long non-coding RNAs [lncRNAs], microRNAs [miRNAs], and mRNAs) were extracted from The Cancer Genome Atlas (TCGA) database. The DLEU2L-hsa-miR-100-5p/ hsa-miR-99a-5p-TAOK1 ceRNA network related to the prognosis of HCC was obtained by performing bioinformatics analysis. Importantly, we identified the DLEU2L/TAOK1 axis in the ceRNA by using correlation analysis, and it appeared to become a clinical prognostic model by Cox regression analysis. Furthermore, methylation analyses suggested that the abnormal upregulation of the DLEU2L/TAOK1 axis likely resulted from hypomethylation, and immune infiltration analysis showed that the DLEU2L/TAOK1 axis may have an impact on the changes in the tumor immune microenvironment and the development of HCC. In summary, the current study constructing a ceRNA-based DLEU2L/TAOK1 axis might be a novel important prognostic factor associated with the diagnosis and prognosis of HCC.

RESUMO

Hypoxia­inducible­factor 1α (HIF­1α) is a marker for poor prognosis in the majority of the cancer types, and it has been revealed to be essential for maintaining cancer stem cells (CSCs). In the present study, it was determined that the expression of HIF­1α and CSC­related genes under hypoxic conditions was upregulated. Stable knockdown of HIF­1α significantly inhibited cell proliferation, migration and tumour growth in vivo in oesophageal squamous cell carcinoma (ESCC). A previous study revealed that the Wnt/ß­catenin pathway may play a key role in maintenance and progression of CSCs. Therefore, it was also revealed that stable knockdown of HIF­1α reduced the formation of spheroid body cells, the expression of CSC­related genes and Wnt/ß­catenin pathway­related target genes, as well as the activity of the Wnt/ß­catenin pathway. Collectively, the present results indicated that HIF­1α may regulate the stemness of ESCC by activating the Wnt/ß­catenin pathway.
