Promotion of a synthetic degradation of activated STAT6 by PARP-1 inhibition: roles of poly(ADP-ribosyl)ation, calpains and autophagy. J Transl Med 2022; 20:521. [PMID: 36348405 PMCID: PMC9644602 DOI: 10.1186/s12967-022-03715-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 10/20/2022] [Indexed: 11/10/2022] Open
Abstract
Background We reported that PARP-1 regulates genes whose products are crucial for asthma, in part, by controlling STAT6 integrity speculatively through a calpain-dependent mechanism. We wished to decipher the PARP-1/STAT6 relationship in the context of intracellular trafficking and promoter occupancy of the transcription factor on target genes, its integrity in the presence of calpains, and its connection to autophagy. Methods This study was conducted using primary splenocytes or fibroblasts derived from wild-type or PARP-1−/− mice and Jurkat T cells to mimic Th2 inflammation. Results We show that the role for PARP-1 in expression of IL-4-induced genes (e.g. gata-3) in splenocytes did not involve effects on STAT6 phosphorylation or its subcellular trafficking, rather, it influenced its occupancy of gata-3 proximal and distal promoters in the early stages of IL-4 stimulation. At later stages, PARP-1 was crucial for STAT6 integrity as its inhibition, pharmacologically or by gene knockout, compromised the fate of the transcription factor. Calpain-1 appeared to preferentially degrade JAK-phosphorylated-STAT6, which was blocked by calpastatin-mediated inhibition or by genetic knockout in mouse fibroblasts. The STAT6/PARP-1 relationship entailed physical interaction and modification by poly(ADP-ribosyl)ation independently of double-strand-DNA breaks. Poly(ADP-ribosyl)ation protected phosphorylated-STAT6 against calpain-1-mediated degradation. Additionally, our results show that STAT6 is a bonafide substrate for chaperone-mediated autophagy in a selective and calpain-dependent manner in the human Jurkat cell-line. The effects were partially blocked by IL-4 treatment and PARP-1 inhibition. Conclusions The results demonstrate that poly(ADP-ribosyl)ation plays a critical role in protecting activated STAT6 during Th2 inflammation, which may be synthetically targeted for degradation by inhibiting PARP-1.

E3 ubiquitin ligase Casitas B lineage lymphoma-b and its potential therapeutic implications for immunotherapy. Clin Exp Immunol 2021; 204:14-31. [PMID: 33306199 DOI: 10.1111/cei.13560] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 11/17/2020] [Accepted: 12/02/2020] [Indexed: 12/25/2022] Open
Abstract
The distinction of self from non-self is crucial to prevent autoreactivity and ensure protection from infectious agents and tumors. Maintaining the balance between immunity and tolerance of immune cells is strongly controlled by several sophisticated regulatory mechanisms of the immune system. Among these, the E3 ligase ubiquitin Casitas B cell lymphoma-b (Cbl-b) is a newly identified component in the ubiquitin-dependent protein degradation system, which is thought to be an important negative regulator of immune cells. An update on the current knowledge and new concepts of the relevant immune homeostasis program co-ordinated by Cbl-b in different cell populations could pave the way for future immunomodulatory therapies of various diseases, such as autoimmune and allergic diseases, infections, cancers and other immunopathological conditions. In the present review, the latest findings are comprehensively summarized on the molecular structural basis of Cbl-b and the suppressive signaling mechanisms of Cbl-b in physiological and pathological immune responses, as well as its emerging potential therapeutic implications for immunotherapy in animal models and human diseases.

[PMID: 31061237 PMCID: PMC6535075 DOI: 10.18632/aging.101949] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Accepted: 04/29/2019] [Indexed: 04/12/2023]
Abstract
Endoplasmic reticulum (ER) stress in beta cells induces a signaling network called the unfolded protein response (UPR), which plays a dual role in diabetes. A key regulator of ER-stress and UPR, the orosomucoid 1-like protein 3 (ORMDL3), has been shown to regulate airway remodeling through a major UPR protein, activating transcription factor 6 (ATF6), but the contribution of this regulatory axis to compensatory pancreatic beta cell proliferation in diabetes has not been studied. Here, we detected significantly lower levels of ORMDL3 mRNA in leukocytes of peripheral blood specimens from type 1 diabetes (T1D) children, compared to normal children. Moreover, these ORMDL3 levels in T1D children exhibited further decreases upon follow-up. ORMDL3 levels in islets from NOD mice, a mouse model for T1D in humans, showed a mild increase before diabetes onset, but a gradual decrease subsequently. In high glucose culture, beta cell proliferation, but not apoptosis, was increased by overexpression of ORMDL3 levels, likely mediated by its downstream factor ATF6. Mechanistically, ORMDL3 transcriptionally activated ATF6, which was confirmed in a promoter reporter assay. Together, our data suggest that ORMDL3 may increase beta cell proliferation through ATF6 as an early compensatory change in response to diabetes.

Abstract
A growing body of evidence has suggested the genetic association of ORMDL3 gene (ORMDL Sphingolipid Biosynthesis Regulator 3) polymorphisms with a diverse set of inflammatory disorders that include bronchial asthma, inflammatory bowel disease, ankylosing spondylitis and atherosclerosis. Gene functional investigations have revealed the particular relevance of ORMDL3 in endoplasmic reticulum stress, lipid metabolism and inflammatory reactions. Additionally, several reports have recently added a new dimension to our understanding of the modulation of ORMDL3 gene expression in inflammation. This mini-review summarizes the pertinent publications regarding the genetic association studies and mechanistic exploration of ORMDL3 in common inflammatory disorders.

Abstract
Orosomucoid 1-like protein 3 (ORMDL3) is an asthma candidate gene associated with virus-triggered recurrent wheeze. Stimulator of interferon gene (STING) controls TLR-independent cytosolic responses to viruses. However, the association of STING with ORMDL3 is unclear. Here, we have shown that ORMDL3 expression shows a linear correlation with STING in recurrent wheeze patients. In elucidating the molecular mechanisms of the ORMDL3-STING relationship, we found that STING promoted the transcriptional activity of ORMDL3, which was significantly associated with increased levels of interferon regulatory factor 3 (IRF3) and signal transducer and activator of transcription 6 (STAT6). Further study showed that via activation of TANK binding kinase 1 (TBK1), STING enhanced the phosphorylation and binding of IRF3 and STAT6, which upregulated ORMDL3 by binding to the promoter. Our results showed that STING positively regulated ORMDL3 through the TBK1-IRF3-STAT6 complex.

Mechanisms and roles by which IRF-3 mediates the regulation of ORMDL3 transcription in respiratory syncytial virus infection. Int J Biochem Cell Biol 2017; 87:8-17.

Abstract
Respiratory syncytial virus (RSV) is the leading cause of bronchiolitis in infancy, which is a major risk factor for recurrent wheezing and asthma. Orosomucoid 1-like protein 3 (ORMDL3) has been reported to associate with virus-triggered recurrent wheezing and asthma in children. However, little is known about how ORMDL3 is involved into RSV infection. In this study, we showed that the mRNA expression of ORMDL3 is significantly increased in the peripheral blood lymphocytes of infants with RSV-induced bronchiolitis compared with uninfected controls, also increased in bronchial epithelial cells and lung fibroblasts following RSV infection in vitro. To investigate the underlying mechanisms of RSV-induced ORMDL3 expression, we performed in silico analysis of the binding sites of several transcription factors in the ORMDL3 promoter. The proximal interferon-regulatory factor-3 (IRF-3) binding site positively regulated ORMDL3 transcription following exposure to RSV, as determined through mutational analysis. Overexpression and RNA interference experiments targeting IRF-3 showed that it regulates the expression of ORMDL3 following RSV exposure. Electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation (ChIP) assay showed that IRF-3 binds directly to the promoter of the ORMDL3 gene. Furthermore, we confirmed that expression of IRF-3 is significantly increased and shows a strong linear correlation with increased ORMDL3 in the peripheral blood lymphocytes from infants with RSV-induced bronchiolitis. Our results indicate that IRF-3 is an important regulator of ORMDL3 induction following RSV infection by binding directly to the promoter of ORMDL3, which may be implicated in the inflammatory and immune reactions involved in bronchiolitis and wheezing diseases.
