A total of 237 non-regular exercise Han college students were recruited in a 12-week HIIT program, attending sessions 3 times a week. Before and after the HIIT program, their body composition was measured. DNA from the white blood cells was extracted and genotyped. PLINK (V1.09) software was used for quality control screening of SNPs loci, and a linear regression model was constructed to analyze the association between <i>ADCY3</i> gene SNPs loci and body composition. ANOVA multiple comparisons (LSD) were performed to test the difference between groups, with the significance level set at 0.05. The results showed that: 1) A total of 22 SNPs loci were identified by the gene microarray scanning of <i>ADCY3</i> gene, with 15 of them meeting the quality control criteria. The rs6753096 locus was associated with the training effect of HIIT on body composition; 2) The rs6753096 locus was not associated with pre-HIIT body composition; 3) Compared with volunteers with TT genotype, those with CT/CC genotype exhibited significant decrease in body mass index (BMI) and total body fat after training (<i>P</i> < 0.05); Male volunteers carrying the C allele had more significant training changes in skeletal muscle and lean body weight, while HIIT was more effective in decreasing body fat in female volunteers with CT/CC genotype; 4) The rs6753096 locus was significantly correlated with body fat sensitivity to HIIT (<i>P</i> = 0.0475), indicating that volunteers with CT/CC genotype were more sensitive to HIIT. In conclusion, 12-week HIIT program effectively improved the body composition of college students. The <i>ADCY3</i> gene rs6753096 locus is not associated with pre-HIIT body composition, but it is associated with body composition sensitivity to HIIT, with individuals carrying CT/CC genotype showing greater responsiveness to HIIT.</p>","PeriodicalId":7134,"journal":{"name":"生理学报","volume":"76 6","pages":"970-978"},"PeriodicalIF":0.0,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142942495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under normal physiological conditions, these intersecting signal pathways regulate and coordinate the hypertrophy and atrophy of skeletal muscles, balancing the protein synthesis and degradation of muscle. When the total rate of protein synthesis exceeds that of protein degradation, the muscle gradually becomes enlarged, while when the total rate of protein synthesis is lower than that of protein degradation, the muscle shrinks. Myocyte atrophy mainly involves two protein degradation pathways, namely ubiquitin-proteasome and autophagy-lysosome. Protein degradation pathway is activated during muscle atrophy, resulting in the loss of muscle mass. Muscle atrophy can occur under various conditions such as malnutrition, aging and cachexia. Skeletal muscle atrophy caused by orthopedic diseases mainly includes disuse muscular atrophy caused by fracture and denervation muscular atrophy. The signal pathways that control and coordinate protein synthesis and degradation in skeletal muscle include insulin-like growth factor 1 (IGF1)-Akt-mammalian target of rapamycin (mTOR), myostatin-activin A-Smad, G protein α inhibitory peptide 2 (Gαi2)-PKC, nuclear factor κB (NF-κB), ectodysplasin A2 receptor (EDA2R)-NF-κB inducing kinase (NIK) and mitogen-activated protein kinase (MAPK) pathways.

Addictive drugs will bring users a strong sense of euphoria and promote drug seeking. Once the drug is withdrawn, there will be withdrawal symptoms such as strong negative emotions and uncomfortable physical reactions. The recurrence of context-induced withdrawal memory is an important reason for drug relapse. Our previous study has shown increased c-Fos expression in prelimbic cortex (PrL) neurons projecting to paraventricular nucleus of the thalamus (PVT) (PrL^-PVT) during conditioned context-induced retrieval of morphine withdrawal memory. However, whether PrL^-PVT neurons are involved in withdrawal memory retrieval and the underlying molecular mechanisms remain unknown. In this study, we used conditioned place aversion (CPA) model combined with <i>in vivo</i> calcium signal recording, chemogenetics and nucleus drug injection methods to investigate the role and molecular mechanism of PrL^-PVT neurons in retrieval of morphine withdrawal memory. The results showed that the calcium signals of PrL^-PVT neurons were significantly enhanced by withdrawal-related context; Inhibition of PrL^-PVT neurons blocked the conditioned context-induced morphine withdrawal memory retrieval; Activation of PrL^-PVT neurons caused animals to escape from the context; After the inhibition of NMDA receptors in the PrL, withdrawal-related context failed to increase c-Fos and Arc expressions in PrL^-PVT neurons. The above results suggest that NMDA receptors in PrL^-PVT neurons are associated with retrieval of morphine withdrawal memory.

The residues which play a crucial role in the N-end rule pathway are called degrons, also known as N-degrons, as they are usually unstable at the N-terminal end of the protein. Currently, several N-end rule pathways have been identified in the eukaryotes, including the Arg/N-end rule, Ac/N-end rule, and Pro/N-end rule pathways, as well as the recently discovered Gly/N-end rule pathway. The Ac/N-end rule pathway targets proteins containing N-terminal acetylation (Nt-acetylation) residues. The Arg/N-end rule pathway, on the other hand, targets certain unacetylated residues and involves N-terminal arginylation. For proteins with N-terminal proline (Pro) and glycine (Gly) residues, they are neither modified by acetylation nor recognized through the Arg/N-end rule pathway. Therefore, these proteins are primarily recognized and degraded through the Pro/N-end rule pathway and the Gly/N-end rule pathway. The regulation of specific proteins through N-end rule pathway-mediated degradation plays an important role in numerous physiological and pathological processes, such as cardiovascular development, neurogenesis, meiosis, spermatogenesis, HPV infection, and cell apoptosis. In this review, we summarize the role and mechanisms of several known N-end rule pathways and discuss their relationship with certain diseases. As an independent protein degradation system, the N-end rule pathways still hold countless biological secrets waiting for exploring.
