Transcriptomics based identification of S100A3 as the key anti-hepatitis B virus factor of 16F16. Biomed Pharmacother 2023; 163:114904. [PMID: 37207431 DOI: 10.1016/j.biopha.2023.114904] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 05/12/2023] [Accepted: 05/16/2023] [Indexed: 05/21/2023] Open
Abstract
More than 250 million people worldwide have chronic hepatitis B virus (HBV) infections, resulting in over 1 million annual fatalities because HBV cannot be adequately treated with current antivirals. Hepatocellular carcinoma (HCC) risk is elevated in the presence of the HBV. Novel and powerful medications that specifically target the persistent viral components are needed to remove infection. This study aimed to use HepG2.2.15 cells and the rAAV-HBV1.3 C57BL/6 mouse model established in our laboratory to examine the effects of 16F16 on HBV. The transcriptome analysis of the samples was performed to examine the impact of 16F16 therapy on host factors. We found that the HBsAg and HBeAg levels significantly decreased in a dose-dependent manner following the 16F16 treatment. 16F16 also showed significant anti-hepatitis B effects in vivo. The transcriptome analysis showed that 16F16 regulated the expression of several proteins in HBV-producing HepG2.2.15 cells. As one of the differentially expressed genes, the role of S100A3 in the anti-hepatitis B process of 16F16 was further investigated. The expression of the S100A3 protein significantly decreased following the 16F16 therapy. And upregulation of S100A3 caused an upregulation of HBV DNA, HBsAg, and HBeAg in HepG2.2.15 cells. Similarly, knockdown of S100A3 significantly reduced the levels of HBsAg, HBeAg, and HBV DNA. Our findings proved that S100A3 might be a new target for combating HBV pathogenesis. 16F16 can target several proteins involved in HBV pathogenesis, and may be a promising drug precursor molecule for the treatment of HBV.

New and Old Genes Associated with Primary and Established Responses to Cisplatin and Topotecan Treatment in Ovarian Cancer Cell Lines. Molecules 2017; 22:molecules22101717. [PMID: 29027969 PMCID: PMC6151558 DOI: 10.3390/molecules22101717] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 09/29/2017] [Accepted: 10/06/2017] [Indexed: 02/07/2023] Open
Abstract
Low efficiency of chemotherapy in ovarian cancer results from the development of drug resistance. Cisplatin (CIS) and topotecan (TOP) are drugs used in chemotherapy of this cancer. We analyzed the development of CIS and TOP resistance in ovarian cancer cell lines. Incubation of drug sensitive cell lines (W1 and A2780) with cytostatic drugs was used to determine the primary response to CIS and TOP. Quantitative polymerase chain reaction (Q-PCR) was performed to measure the expression levels of the genes. We observed decreased expression of the MCTP1 gene in all resistant cell lines. We observed overexpression of the S100A3 and HERC5 genes in TOP-resistant cell lines. Increased expression of the S100A3 gene was also observed in CIS-resistant A2780 sublines. Overexpression of the C4orf18 gene was observed in CIS- and TOP-resistant A2780 sublines. A short time of exposure to CIS led to increased expression of the ABCC2 gene in the W1 and A2780 cell lines and increased expression of the C4orf18 gene in the A2780 cell line. A short time of exposure to TOP led to increased expression of the S100A3 and HERC5 genes in both sensitive cell lines, increased expression of the C4orf18 gene in the A2780 cell line and downregulation of the MCTP1 gene in the W1 cell line. Our results suggest that changes in expression of the MCTP1, S100A3 and C4orf18 genes may be related to both CIS and TOP resistance. Increased expression of the HERC5 gene seems to be important only in TOP resistance.

Abstract
The fifth most common cancer worldwide is hepatocellular carcinoma (HCC), which has an annual mortality rate of ~800,000. Although surgical procedures for HCC, such as hepatic resection and liver transplantation, have progressed and the outcomes of patients have improved, HCC is still characterized by frequent recurrence, even after liver transplantation. In the present study the expression of the protein coding gene, S100 calcium binding protein A3 (S100A3), was observed in 62 HCC tissues and tumor-surrounding tissues. The present study indicated that S100A3 activation was involved in tumorigenesis and tumor aggressiveness. The protein and mRNA expression levels of S100A3 in the human HCC cell line (HepG2) were investigated using western blotting and reverse transcription-quantitative polymerase chain reaction analysis, respectively. The function of sodium cantharidinate in inducing HCC cell apoptosis was also investigated. Sodium cantharidinate inhibited the protein and gene expression of S100A3 in HepG2 cells in vitro. These data suggested that S100A3 has an important role in human HCC. The present study indicates that the functional properties of sodium cantharidinate are promising for the development of a novel drug that may control the expression of S100A3 and improve the treatment of human HCC in the near future.

Abstract
The S100 proteins are a unique class of EF-hand Ca(2+) binding proteins distributed in a cell-specific, tissue-specific, and cell cycle-specific manner in humans and other vertebrates. These proteins are distinguished by their distinctive homodimeric structure, both intracellular and extracellular functions, and the ability to bind transition metals at the dimer interface. Here we summarize current knowledge of S100 protein binding of Zn(2+), Cu(2+) and Mn(2+) ions, focusing on binding affinities, conformational changes that arise from metal binding, and the roles of transition metal binding in S100 protein function.

Abstract
Colorectal cancer (CRC) is a leading cause of cancer-related mortality. The early diagnosis and treatment of CRC is the key to improving the survival of patients who may benefit from adjuvant chemotherapy. In the present study, the protein expression of S100A3 was observed in a cohort of 20 patients with cancer, which indicated that S100A3 activation was involved in tumorigenesis. In addition, the anticancer activity of cantharidinate was investigated using immunohistochemistry and quantitative polymerase chain reaction (qPCR) analysis. The protein expression of S100A3 was observed to increase by 2.4-fold in human CRC cells compared with the expression level in normal control cells (P<0.01). Cantharidinate inhibited the protein and gene expression of S100A3 in UCT-116 human CRC cells in vitro. These results suggested that S100A3 is important in human CRC. Cantharidinate has the potential to be considered as a novel adjuvant drug for controlling the expression of S100A3 in human CRC as it exhibits preventive effects.

Abstract
The S100A3 homotetramer assembles upon citrullination of a specific symmetric Arg51 pair on its homodimer interface in human hair cuticular cells. Each S100A3 subunit contains two EF-hand-type Ca(2+)-binding motifs and one (Cys)3His-type Zn(2+)-binding site in the C-terminus. The C-terminal coiled domain is cross-linked to the presumed docking surface of the dimeric S100A3 via a disulfide bridge. The aim of this study was to determine the structural and functional role of the C-terminal Zn(2+)-binding domain, which is unique to S100A3, in homotetramer assembly. The binding of either Ca(2+) or Zn(2+) reduced the α-helix content of S100A3 and modulated its affinity for the other cation. The binding of a single Zn(2+) accelerated the Ca(2+)-dependent tetramerization of S100A3 while inducing an extensive unfolding of helix IV. The Ca(2+) and Zn(2+) binding affinities of S100A3 were enhanced when the other cation bound in concert with the tetramerization of S100A3. Small angle scattering analyses revealed that the overall structure of the S100A3 tetramer bound both Ca(2+) and Zn(2+) had a similar molecular shape to the Ca(2+)-bound form in solution. The binding states of the Ca(2+) or Zn(2+) to each S100A3 subunit within a homotetramer appear to be propagated by sensing the repositioning of helix III and the rearrangement of the C-terminal tail domain. This article is part of a Special Issue entitled: 12th European Symposium on Calcium.
