Cullin-associated and neddylation-dissociated 1 protein (CAND1) governs cardiac hypertrophy and heart failure partially through regulating calcineurin degradation. Pharmacol Res 2022; 182:106284. [PMID: 35661710 DOI: 10.1016/j.phrs.2022.106284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 05/16/2022] [Accepted: 05/29/2022] [Indexed: 11/19/2022]
Abstract
Pathological cardiac hypertrophy is a process characterized by significant disturbance of protein turnover. Cullin-associated and Neddylation-dissociated 1 (CAND1) acts as a coordinator to modulate substrate protein degradation by promoting the formation of specific cullin-based ubiquitin ligase 3 complex in response to substrate accumulation, which thereby facilitate the maintaining of normal protein homeostasis. Accumulation of calcineurin is critical in the pathogenesis of cardiac hypertrophy and heart failure. However, whether CAND1 titrates the degradation of hypertrophy related protein eg. calcineurin and regulates cardiac hypertrophy remains unknown. Therefore, we aim to explore the role of CAND1 in cardiac hypertrophy and heart failure and the underlying molecular mechanism. Here, we found that the protein level of CAND1 was increased in cardiac tissues from heart failure (HF) patients and TAC mice, whereas the mRNA level did not change. CAND1-KO+/- aggravated TAC-induced cardiac hypertrophic phenotypes; in contrast, CAND1-Tg attenuated the maladaptive cardiac remodeling. At the molecular level, CAND1 overexpression downregulated, whereas CAND1-KO+/- or knockdown upregulated calcineurin expression at both in vivo and in vitro conditions. Mechanistically, CAND1 overexpression favored the assembly of Cul1/atrogin1/calcineurin complex and rendered the ubiquitination and degradation of calcineurin. Notably, CAND1 deficiency-induced hypertrophic phenotypes were partially rescued by knockdown of calcineurin, and application of exogenous CAND1 prevented TAC-induced cardiac hypertrophy. Taken together, our findings demonstrate that CAND1 exerts a protective effect against cardiac hypertrophy and heart failure partially by inducing the degradation of calcineurin.

Interplay between two myogenesis-related proteins: TBP-interacting protein 120B and MyoD. Gene 2012; 504:213-9.

Abstract
Gene expression in myogenesis is governed by multiple myogenic factors including MyoD. Previously, we demonstrated that TBP-interacting protein 120B (TIP120B) promotes in vitro myogenesis through its anti-ubiquitination ability. In this study, we investigated interplay between MyoD and TIP120B. Mouse C2C12 cells subjected to myotube differentiation contained increased amounts of TIP120B and MyoD. Dexamethasone, which inhibits myogenic signaling, decreased the amounts of those proteins. Mouse and human TIP120B promoters, which carry multiple E-box motifs, were potentiated by MyoD. In the human TIP120B, a proximal E-box binds to MyoD in vitro and exhibits MyoD-dependent transcription activation function. Expression of the endogenous TIP120B gene was correlated with the level of MyoD in different types of muscle-related cells. Furthermore, MyoD binds specifically to a proximal E-box-carrying promoter region in chromatin. Proteasome-sensitive MyoD was increased and decreased by overexpression and knockdown of TIP120B, respectively. Moreover, stability of MyoD was increased by TIP120B. The results suggest that MyoD and TIP120B potentiate each other at gene expression and post-translation levels, respectively, which may promote myogenesis cooperatively.

Abstract
Despite fast protein degradation in muscles, protein concentrations remain constant during differentiation and maintenance of muscle tissues. Myogenin, a basic helix-loop-helix-type myogenic transcription factor, plays a critical role through transcriptional activation in myogenesis as well as muscle maintenance. TBP-interacting protein 120/cullin-associated neddylation-dissociated (TIP120/CAND) is known to bind to cullin and negatively regulate SCF (Skp1-Cullin1-F-box protein) ubiquitin ligase, although its physiological role has not been elucidated. We have identified a muscle-specific isoform of TIP120, named TIP120B/CAND2. In this study, we found that TIP120B is not only induced in association with myogenic differentiation but also actively accelerates the myogenic differentiation of C2C12 cells. Although myogenin is a short lived protein and is degraded by a ubiquitin-proteasome system, TIP120B suppressed its ubiquitination and subsequent degradation of myogenin. TIP120B bound to cullin family proteins, especially Cullin 1 (CUL1), and was associated with SCF complex in cells. It was demonstrated that myogenin was also associated with SCF and that CUL1 small interference RNA treatment inhibited ubiquitination of myogenin and stabilized it. TIP120B was found to break down the SCF-myogenin complex. Consequently suppression of SCF-dependent ubiquitination of myogenin by TIP120B, which leads to stabilization of myogenin, can account for the TIP120B-directed accelerated differentiation of C2C12 cells. TIP120B is proposed to be a novel regulator for myogenesis.

Abstract
Cullin-RING ligases (CRLs) regulate diverse cellular functions such as cell cycle progression and cytokine signaling by ubiquitinating key regulatory proteins. The activity of CRLs is controlled by Nedd8 modification of the cullin subunits. Recent reports have suggested that CAND1, which specifically binds to unmodified CUL1 but not to neddylated one, is required for the in vivo function of SCFs, the CUL1-containing CRLs. We show here that CAND1 and COP9 signalosome (CSN), the major deneddylase of cullins, bind to unneddylated CUL1 in a mutually exclusive way. The suppression of CAND1 expression by small inhibitory RNA enhanced the interaction between CUL1 and CSN, suggesting that CAND1 inhibited the binding of CSN to CUL1. We found that the binding of CSN to CUL1 required the four helix bundle in CUL1 C-terminal domain, which was wrapped around by CAND1 in the CAND1-CUL1-Rbx1 complex. CAND1 greatly facilitated CSN-mediated deneddylation of CUL1 in vitro, which was dependent on its binding to CUL1. Our data suggest that enhancement of CSN-mediated deneddylation by CAND1 may contribute to its function as a positive regulator of SCFs in vivo.

Abstract
TBP-interacting protein 120 (TIP120) has been identified by TBP-mediated affinity screening. Classical TIP120, TIP120A, which functions as a transcriptional activator, is expressed ubiquitously whereas TIP120B is specifically expressed in muscle tissues. We found that TIP120B gene was induced in C2C12 myoblasts when these cells differentiated into myotubes, whereas TIP120A gene expression was down-regulated. Whole-mount in situ hybridization revealed that TIP120B mRNA was concentrated in limb buds of mouse embryos. TIP120B is thus thought to be a myogenesis-responding gene. We searched for TIP120B-binding proteins by yeast two-hybrid screening and identified NOT3. NOT3, a constituent of CCR4-NOT complex, is suggested to be involved in global gene regulation via interaction with TBP. The human NOT3 (hNOT3L), which we identified, has an extra 144 amino acids (AAs) at the C-terminus of a classical NOT3. GST pull-down and yeast two-hybrid assays demonstrated that hNOT3L is associated with TIP120B but not with TIP120A. A hNOT3L-specific C-terminal region of 92 AAs was assigned as a TIP120B-interacting domain. The N-terminus of 209 AAs of TIP120B was responsible for this binding. TIP120B presumably affects tissue-specific transcriptional regulation via interaction with NOT3.
