ABSTRACT
@#Autophagy is a process of self-phagocytosis of lysosomal degrading substances in cells. Under normal conditions,cells can use autophagy to remove their own garbage to provide energy,while in a state of stress,autophagy can also be activated,resulting in cell damage and death,which can seriously lead to cancer. B-cell lymphoma-2-interacting myosin-like coiled-coil protein(Beclin1) is a central node in the autophagy pathway and interacts with a variety of proteins to regulate the formation and maturation of autophagosomes. Kinase mediates the protein modification of Beclin1 during autophagy,which will affect its activity and interaction with other autophagy-related proteins. Beclin1 is closely related to the occurrence and development of tumors. Therefore,this paper focused on the research progress on the mechanism and protein modification of Beclin1 in autophagy,in view to providing a reference for the research of targeted drugs of tumor autophagy.
ABSTRACT
Abstract Long-chain non-encoded RNAs (lncRNAs) are important in many life activities and can participate in the occurrence of hepatocellular carcinoma (HCC). Moreover, lncRNAs can be used as basis for developing new strategies to hinder liver cancer. To investigate the utility of lncRNAs in HCC as potential biomarkers for early detection and diagnosis, we mined genomic data from the Cancer Genome Atlas (TCGA), and analyzed the gene expressions from 374 tumor patients and 50 normal patients. The abnormal expressions of 387 differentially expressed lncRNAs (DElncRNAs) were identified from a total of 3099 lncRNAs. Moreover, 18 modules were divided based on WGCNA, and 2 of the 18 modules were positively correlated with stage and grade, and negatively correlated with survival time. Finally, 10 lncRNAs were found and their main functions are the enhancement of cellular metabolic capacity and cell proliferation. These 10 lncRNAs may serve as novel prognostic markers and therapeutic targets, and may help guide subsequent studies on HCC.
