26768247 Our data suggest that FBXO32 is a candidate gene for recessive familial dilated cardiomyopathy. Acting as a cardiac ubiquitin ligase, mutated FBXO32 could perturb the degradation of target proteins in the ubiquitin proteasome system.
26753747 Our results indicate that abnormal SCF activity with subsequent impairment of the autophagic flux due to a novel FBXO32 mutation is implicated in the pathogenesis of Dilated cardiomyopathy .
26048142 Expression of USP19 correlates with that of MuRF1 and MAFbx/atrogin-1 in skeletal muscles
25944903 FBXO32 targets Lys-326 of c-Myc to form polyubiquitin chains, resulting in inhibition of cell proliferation.
25876656 Vitamin D3 might have an inhibitory effect on the expression of MAFbx and MuRF1 in skeletal muscle.
25760630 Atrogin-1 expression tended to be increased in the skeletal muscle of patients with malignant disease even before cancer related cachexia weight loss.
25096180 both MuRF1 and MAFbx are enriched in skeletal, cardiac, and smooth muscle--REVIEW
24798237 FBXO32 methylation status and protein expression were independently associated with survival in ESCC. FBXO32 may be a functional tumor suppressor. Its inactivation through promoter methylation could play an important role in ESCC carcinogenesis.
24650875 MAFbx not only regulates protein degradation, but also reduces protein synthesis, exerting a dual role in regulating cardiac mass and preventing from cardiac hypertrophy.
24458747 In conclusion, atrogin-1, MuRF1, FOXO1/3A, and eIF3-f mRNA, and protein levels, are differentially regulated by exercise contraction mode but not WPH supplementation combined with hypertrophy-inducing training.
24213577 EZH2 is a key factor in the proliferation and survival of PAX3-FOXO1 alveolar RMS cells working, at least in part, by repressing FBXO32
23844868 Quadriceps muscle atrogin-1 levels were lower in COPD patients than controls, but similar in patients with a low and normal fat-free mass index. Atrogin1 levels were not associated with quadriceps fiber cross-sectional area or strength in patients.
23816995 ATROGIN1 gene expression is increased in patients with severe burn injury.
22815045 Data suggest expression of atrogin-1 and MuRF-1 (muscle-specific RING finger protein 1) play role in aging-related decrease in muscle mass (i.e., sarcopenia); up-regulation of atrogin-1/MuRF-1 has potential to prevent/reverse sarcopenia. [REVIEW]
22590725 In a transgenic mouse model of autoimmune myositis, cellular inflammation is associated with FOXO3A translocation and Atrogin-1 induction.
22476926 Resistance exercise resulted in a significant downregulation of MSTN and FBXO32 mRNA expression and a significant upregulation in FSTL3 and SMURF1 mRNA expression, and carbohydrate and protein feeding have little influence on the these markers expression.
22311109 Cardiac and vascular atrogin-1 mRNA expression is not associated with dexamethasone efficacy in the monocrotaline model of pulmonary hypertension.
22249105 MAFbx contains two functional nuclear localization signals (NLS). Mutation or deletion of only one NLS induced cytoplasmic localization of MAFbx.
22127230 investigation of factors regulating expression of two ubiquitin ligases (MAFbx and MURF1) in skeletal muscle (i.e., vastus lateralis): effects of resistance exercise and anabolic dietary supplement (i.e., branched-chain amino acids)
21725612 SerpinB5 interacts with KHDRBS3 and FBXO32, and KHDRBS3 can interact with FBXO32 mRNA.
21304964 11beta-HSD1 controls glucocorticoid-induced protein degradation in human and murine skeletal muscle via regulation of the E3 ubiquitin ligases Atrogin-1 and MuRF-1.
20833824 atrophic AKT-FOXO signaling play major roles in eliciting pathological changes associated with diaphragm disuse.
20065949 The novel tumor suppressor FBXO32 is epigenetically silenced in ovarian cancer cell lines with disrupted TGF-beta/SMAD4 signaling, and FBXO32 methylation status predicts survival in patients with ovarian cancer.
19859778 Reduced expression of MuRF1 and MAFbx in the myocardium might permit hypertrophy characteristic of the early post-infarction remodeling phase.
19850579 atrogin-1 specifically targets truncated M7t-cMyBP-C, but not WT-cMyBP-C, for proteasomal degradation and that MuRF1 indirectly reduces cMyBP-C levels by regulating the transcription of myosin heavy chain.
19453261 Observational study of gene-disease association. (HuGE Navigator)
18681786 Review discusses findings implicating atrogin-1, a gene required for muscle atrophy, in the pathophysiology of statin-induced muscle injury.
18599544 Testosterone represses MAFbx expression via interactions of the AR with Oct-1.
17992259 atrogin-1 may be a critical mediator of the muscle damage induced by statins.
17977773 Results showed upregulation of MuRf1 and MAFbx in atrophies muscle and support their role as regulatory peptides in various conditions which lead to muscle atrophy.
17971512 MuRF-1 and MAFbx, are differently affected by the exercise as well as by repeated exercise
17901116 Expression of mRNA for MuRF-1 increased approximately 3-fold at 10 days without changes in MAFbx or tripeptidyl peptidase II mRNA, but all decreased between 10 and 21 days of muscle disuse.
17609255 We conclude that smoking impairs the muscle protein synthesis process and increases the expression of genes associated with impaired muscle maintenance; smoking therefore likely increases the risk of sarcopenia.
17519359 CSRP3, MUSTN1, SIX1, and FBXO32 expression changes in response to lengthening and shortening contractions in human muscle
17478621 Atrogin-1 mRNA expression was significantly increased in quadriceps of patients with COPD; transcriptional regulation of atrogin-1 and MuRF1 may occur via FoxO-1, but independently of AKT
16868939 results suggest that Cbl-b- or atrogin-1-mediated ubiquitination plays an important role in unloading-induced muscle atrophy, and that unloading stress may preferentially inhibit transcriptional responses in skeletal muscle
16507768 Human skeletal muscle atrophy in the amyotrophic lateral sclerosis shows an increase in atrogin-1 & a decrease in Akt. The transcriptional regulation of human atrogin-1 may be controlled by an Akt-mediated transcription factor other than FKHR.
