Abstract
Malignant tumor is still a major problem worldwide. During tumorigenesis or tumor development, tumor suppressor p53-binding protein 2 (TP53BP2), also known as apoptosis stimulating protein 2 of p53 (ASPP2), plays a critical role in p53 dependent and independent manner. Expression of TP53BP2 is highly correlated with the prognosis and survival rate of malignant tumor patients. TP53BP2 can interact with p53, NF-κB p65, Bcl-2, HCV core protein, PP1, YAP, CagA, RAS, PAR3, and other proteins to regulate cell function. Moreover, TP53BP2 can also regulate the proliferation, apoptosis, autophagy, migration, EMT and drug resistance of tumor cells through downstream signaling pathways, such as NF-κB, RAS/MAPK, mevalonate, TGF-β1, PI3K/AKT, aPKC-ι/GLI1 and autophagy pathways. As a potential therapeutic target, TP53BP2 has been attracted more attention. We review the role of TP53BP2 in tumorigenesis or tumor development and the signal pathway involved in TP53BP2, which may provide more deep insight and strategies for tumor treatment.

Abstract
Alpha-herpesvirus thymidine kinase (TK) genes are virulence-related genes and are nonessential for viral replication; they are often preferred target genes for the construction of gene-deleted attenuated vaccines and genetically engineered vectors for inserting and expressing foreign genes. The enzymes encoded by TK genes are key kinases in the nucleoside salvage pathway and have significant substrate diversity, especially the herpes simplex virus 1 (HSV-1) TK enzyme, which phosphorylates four nucleosides and various nucleoside analogues. Hence, the HSV-1 TK gene is exploited for the treatment of viral infections, as a suicide gene in antitumor therapy, and even for the regulation of stem cell transplantation and treatment of parasitic infection. This review introduces the effects of α-herpesvirus TK genes on viral virulence and infection in the host and classifies and summarizes the current main application domains and potential uses of these genes. In particular, mechanisms of action, clinical limitations, and antiviral and antitumor therapy development strategies are discussed.

ASPP2 enhances chemotherapeutic sensitivity through the down-regulation of XIAP expression in a p53 independent manner in hepatocellular carcinoma. Biochem Biophys Res Commun 2018; 508:769-774. [PMID: 30528232 DOI: 10.1016/j.bbrc.2018.11.181] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 11/20/2018] [Accepted: 11/28/2018] [Indexed: 12/30/2022]
Abstract
Apoptosis stimulated protein of p53-2 (ASPP2) induces the transcription of p53-targeted genes to stimulates its pro-apoptosis function. The poor chemotherapeutic sensitivity is associated with the decreased ASPP2 expression in many human cancers. Here, multiple genes real-time RT-PCR array and western blotting analysis show that ASPP2 suppress the expression of X-linked inhibitor of apoptosis protein (XIAP), determinant of chemoresistance in cancer, in hepatocellular carcinoma (HCC) in a p53-independent manner. Further experiments with ASPP2-rAd and ASPP2-Lv confirmed that ASPP2 enhanced sensitivity of sorafenib to HCC via suppressing XIAP expression. XIAP mainly found on the cytoplasm and perinuclear areas of ASPP2 over-expressed HepG2 cells, while both cytoplasm and nucleus in ASPP2 shut down HepG2 cells. The association of poor sensitivity of sorafenib and XIAP expression was also found both in ASPP2 shut down and overexpress mice, where liver tissue with decreased or increased ASPP2 displayed less or more apoptosis, respectively. Finally, ASPP2 and XIAP expression analyzed in 43 hepatocellular carcinoma tumors and 44 adjacent normal tissues from 38 hepatocellular carcinoma patients for fully understand their expression within HCC patients. Compared with the tumor tissues, ASPP2 mRNA levels were increased, and XIAP levels decreased in the adjacent normal tissues. Taken together, XIAP suppressed ASPP2 increased tumor sensitivity to chemotherapy in a p53-independent manner, which was associated with chemotherapy resistance, suggesting that p53 activation and XIAP suppression were two independent ways that ASPP2 enhance the sensitivity of chemotherapy.

Abstract
The objective of this study was to investigate the effects of ultrasound-guided injection of ultrasound contrast agents (UCAs) and the p53 gene on the treatment of rats with breast cancer (BC). Assembly of the p53 expression vector as well as that of a rat model with BC consisted of 200 successfully modeled rats randomly divided into 5 groups: p53 gene introduction, p53 gene introduction + ultrasound irradiation, p53 gene introduction + UCAs, p53 gene introduction + UCA + ultrasound irradiation, and UCA + ultrasound irradiation groups. Expression of p53 was detected via quantitative real-time polymerase chain reaction (qRT-PCR), western blotting and immunohistochemical staining. In the p53 gene introduction + ultrasound irradiation group, we observed increased tumor volume with blood flow signals around and necrotic tumor tissues with an inhibition rate of 36.30%, as well as higher expression of p53 than that in the p53 gene introduction group and p53 gene introduction + UCA group. In the p53 gene introduction + UCA + ultrasound irradiation group, tumor volume increased slightly with reduced blood flow signals and massive degenerative necrosis of tumor cells was identified with inhibition rate of 62.62%, and expression of p53 was higher than that in the rest groups. Taken together, the key findings obtained from the present study elucidate that injection of p53 gene and UCA microbubbles guided by ultrasound could increase the expression of p53, thus inhibiting the tumor growth in rats with BC.

Int J Oncol 2018; 52:872-880. [PMID: 29393359 DOI: 10.3892/ijo.2018.4263] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2017] [Accepted: 01/12/2018] [Indexed: 11/05/2022] Open
Abstract
Connexin 43 (Cx43) can be modified and regulated by small ubiquitin-like modifier (SUMO)1; however, its role in liver cancer stem cells is poorly understood. In this study, we found a significant difference in the expression of Cx43 and SUMO1 between cancer stem cells and non-cancer stem cells in liver cancer. In liver cancer stem cells, Cx43 was almost absent, although the level of SUMO1 was significantly higher than that in non-cancer stem cells. Further experiments confirmed that the conjugated site of Cx43 by SUMO1 was located in Lys-144 and Lys-237, both of which are highly conserved among species. By the co-expression of Cx43 and SUMO1 in cancer stem cells, the gap junction intercellular communication (GJIC) of liver cancer stem cells was obviously improved. Using this feature, we verified whether it could effectively increase the sensitivity of cancer stem cells to the herpes simplex virus 1 thymidine kinase (HSVtk) gene in combination with ganciclovir (GCV), a conventional chemotherapeutic drug, in vitro and in vivo. As expected, increasing the expression of Cx43 SUMOylation in liver cancer stem cells effectively enhanced their sensitivity to HSVtk/GCV. On the whole, this study revealed a novel method which may be used to effectively restore GJIC in cancer stem cells in liver cancer, which enhances their sensitivity to conventional chemotherapeutic drugs.
