Two Duplicated Ptpn6 Homeologs Cooperatively and Negatively Regulate RLR-Mediated IFN Response in Hexaploid Gibel Carp. Front Immunol 2021; 12:780667.

Abstract
Src homology region 2 domain-containing phosphatase 1 (SHP1), encoded by the protein tyrosine phosphatase nonreceptor type 6 (ptpn6) gene, belongs to the family of protein tyrosine phosphatases (PTPs) and participates in multiple signaling pathways of immune cells. However, the mechanism of SHP1 in regulating fish immunity is largely unknown. In this study, we first identified two gibel carp (Carassius gibelio) ptpn6 homeologs (Cgptpn6-A and Cgptpn6-B), each of which had three alleles with high identities. Then, relative to Cgptpn6-B, dominant expression in adult tissues and higher upregulated expression of Cgptpn6-A induced by polyinosinic-polycytidylic acid (poly I:C), poly deoxyadenylic-deoxythymidylic (dA:dT) acid and spring viremia of carp virus (SVCV) were uncovered. Finally, we demonstrated that CgSHP1-A (encoded by the Cgptpn6-A gene) and CgSHP1-B (encoded by the Cgptpn6-B gene) act as negative regulators of the RIG-I-like receptor (RLR)-mediated interferon (IFN) response via two mechanisms: the inhibition of CaTBK1-induced phosphorylation of CaMITA shared by CgSHP1-A and CgSHP1-B, and the autophagic degradation of CaMITA exclusively by CgSHP1-A. Meanwhile, the data support that CgSHP1-A and CgSHP1-B have sub-functionalized and that CgSHP1-A overwhelmingly dominates CgSHP1-B in the process of RLR-mediated IFN response. The current study not only sheds light on the regulative mechanism of SHP1 in fish immunity, but also provides a typical case of duplicated gene evolutionary fates.

Bufalin inhibits human diffuse large B-cell lymphoma tumorigenesis by inducing cell death through the Ca2+/NFATC1/cMYC pathway. Carcinogenesis 2021; 42:303-314. [PMID: 33124657 DOI: 10.1093/carcin/bgaa108] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 09/22/2020] [Accepted: 10/13/2020] [Indexed: 01/01/2023] Open
Abstract
The 5-year survival rate of diffuse large B-cell lymphoma (DLBCL) can reach 60%. However, nearly half of patients undergo relapse/refractory issues with a survival period of less than 2 years. New therapeutic approaches are therefore needed to improve chemotherapy efficacy and patient survival. Bufalin (BF), isolated from the traditional Chinese medicine Chansu, has been reported to play an anticancer role in multiple cancer cell types. However, there are few reports of the effects of BF on the growth of DLBCL. In the present study, we demonstrated that BF exerts antitumor activity in DLBCL cells, both in vitro and in vivo. Treatment of DLBCL cells with BF resulted in increased proliferation and apoptosis in a dose- and time-dependent manner. Daily intraperitoneal injection of 1.5 mg/kg BF significantly delayed DLBCL xenograft growth in NOD/SCID mice without affecting body weight. Bioinformatics analysis showed that BF may regulate NFATC1 protein and affect expression of its downstream gene, cMYC. Our results suggest that BF can attenuate NFATC1 translocation by reducing the intracellular calcium concentration; BF may also have a low synergistic effect with cyclosporin A. In conclusion, we demonstrated that BF exerts antitumor activity that is mediated at least in part by the Ca2+/NFATC1/cMYC pathway. Our findings suggest that BF can be effectively applied as a novel potential therapeutic agent for DLBCL.
