Abstract
The occurrence and progression of hepatocellular carcinoma (HCC) are affected by complicated signal transduction factors. Our previous study identified Ikaros as a novel reactivated therapeutic target that acts as a transcriptional repressor and reactivates anticancer mechanisms in HCC therapy. Annexin A4 (ANXA4) is a member of the Annexin family that plays an essential role in several cancers, but it has not been investigated in HCC proliferation. Using cDNA microarrays, ANXA4 was shown to be associated with Ikaros in Ikaros-overexpressing cells. The aim of this work was to characterize the relationship between Ikaros and ANXA4 and the role of ANXA4 in HCC. The effect of Ikaros on ANXA4 was analyzed in HCC cell lines and HCC patient samples, and functional recovery experiments were performed between Ikaros and ANXA4. Furthermore, the effect of ANXA4 on cell proliferation in vitro was analyzed by MTT and colony formation assays in HCC cells. We used a subcutaneous xenograft model to elucidate the role of ANXA4 in vivo. We found that ANXA4 overexpression promotes HCC cell proliferation, but Ikaros can inhibit ANXA4 expression by repressing its promoter activity. Moreover, we demonstrated that downregulated expression of ANXA4 inhibited HCC cell proliferation and tumorigenesis in vitro and in vivo. Our findings indicate that ANXA4 may be a critical factor in HCC tumorigenesis. Ikaros is an attractive inhibitor of ANXA4 and may function as an anticancer agent in HCC.

[PMID: 25176043 DOI: 10.1016/j.ydbio.2014.08.025] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2014] [Revised: 08/19/2014] [Accepted: 08/20/2014] [Indexed: 01/27/2023]
Abstract
To gain insight into liver and pancreas development, we investigated the target of 2F11, a monoclonal antibody of unknown antigen, widely used in zebrafish studies for labeling hepatopancreatic ducts. Utilizing mass spectrometry and in vivo assays, we determined the molecular target of 2F11 to be Annexin A4 (Anxa4), a calcium binding protein. We further found that in both zebrafish and mouse endoderm, Anxa4 is broadly expressed in the developing liver and pancreas, and later becomes more restricted to the hepatopancreatic ducts and pancreatic islets, including the insulin producing ß-cells. Although Anxa4 is a known target of several monogenic diabetes genes and its elevated expression is associated with chemoresistance in malignancy, its in vivo role is largely unexplored. Knockdown of Anxa4 in zebrafish leads to elevated expression of caspase 8 and Δ113p53, and liver bud specific activation of Caspase 3 and apoptosis. Mosaic knockdown reveal that Anxa4 is required cell-autonomously in the liver bud for cell survival. This finding is further corroborated with mosaic anxa4 knockout studies using the CRISPR/Cas9 system. Collectively, we identify Anxa4 as a new, evolutionarily conserved hepatopancreatic factor that is required in zebrafish for liver progenitor viability, through inhibition of the extrinsic apoptotic pathway. A role for Anxa4 in cell survival may have implications for the mechanism of diabetic ß-cell apoptosis and cancer cell chemoresistance.

Abstract
Aspirin-exacerbated respiratory disease (AERD) is a clinical syndrome characterized by bronchoconstriction after ingestion of nonsteroidal anti-inflammatory drugs including aspirin. The Ca concentration in bronchial epithelial cells is an important factor for bronchoconstriction. Human annexin A4 (ANXA4) is predominantly expressed in the secretory epithelia in the lung, stomach, intestine, and kidney. Furthermore, translocation and induction of ANXA4 have been observed in human Ca-depleted neutrophils. To investigate the association between annexin A4 polymorphisms and the risk of AERD, we have genotyped 21 variants from 102 AERD subjects and 429 aspirin-tolerant asthma (ATA) controls. Logistic analyses controlling for sex, smoking status, and atopy as covariates were performed to estimate the association between the annexin A4 polymorphisms and AERD. Among these variants, 8 polymorphisms (rs2168116, rs4853017, rs6546547, rs13428251, rs7577864, rs7559354, rs7588022, and rs3816491) and 2 haplotypes (ANXA4-ht3 and ANXA4-ht5) were significantly associated with the risk of AERD. One common polymorphism in intron 11, rs3816491, showed the strongest association signal with susceptibility to aspirin-AERD even after multiple testing corrections (OR=0.57; 95% confidence interval 0.40-0.83; P=0.003; P=0.045 in the codominant model). Although further functional evaluations of replication studies in larger cohorts are required, our findings suggest that the annexin A4 could have susceptibility for AERD.
