Summary: Skeletal muscle memory is a phenomenon that has caught the attention of the scientific community, exercise practitioners, and the public. Research has shown that previous positive experiences with exercise training can enhance the adaptability of skeletal muscle tissue to later retraining, even after a period of exercise cessation or detraining. This review discusses the cellular and epigenetic mechanisms of skeletal muscle memory, as well as the importance of investigating muscle memory for optimizing exercise interventions and developing strategies for muscle wasting conditions and age-related muscle loss. The review also highlights future directions for research in skeletal muscle memory.

Summary: CXXC zinc finger protein 1 (CFP1) is a multitasking protein that plays essential roles during developmental processes by interacting with several proteins and contributing to various epigenetic events. It also impacts DNA methylation and post-translational modification of histone proteins such as lysine acetylation and methylation. Additionally, CFP1's potential role in carcinogenesis and the effects of identified mutations on various cancers will be discussed.

Summary: Mechanically stressed vascular smooth muscle cells (VSMCs) increase the secretion of high mobility group box 1 (HMGB1), and platelet-derived growth factor receptor (PDGFR) signaling plays a crucial role in this process. Inhibiting PDGFR-beta-mediated secretion of HMGB1 in VSMCs may be a promising therapeutic strategy for vascular complications associated with hypertension.

Summary: The study aims to investigate the cardio-protective effects of Kirenol (KRL) against doxorubicin-induced apoptosis in H9c2 cells. Results showed that KRL can activate the Nrf2 signaling pathway and suppress cell apoptosis, thus preventing doxorubicin-induced cardiac oxidative stress and remodeling.

Summary: This study found that Salidroside can significantly inhibit hypertrophic reactions caused by pressure overload and isoproterenol injection. Salidroside prevented the activation of the TAK1-JNK/p38 pathway. In vitro cell experiments demonstrated that TAK1-inhibited cardiomyocytes pre-treated with Salidroside did not have additional attenuation of Ang II-induced cardiomyocyte hypertrophy and signaling pathway activation. The overexpression of constitutively active TAK1 eliminated the protective effects of Salidroside on myocardial hypertrophy. Salidroside treatment in mice decreased TAC-induced TLR4 protein expression. Transfection of small interfering RNA targeting TLR4 did not further decrease the activation of the TAK1/JNK-p38 pathway in cardiomyocytes. In conclusion, Salidroside functions as a TLR4 inhibitor and exerts its anti-hypertrophic action through the TAK1/JNK-p38 pathway.

Summary: The study showed that TGFβ stimulation led to changes in H3K27ac and H3K9ac, with the latter associated with fibrosis pathways. Cholangiocytes predominantly express KAT2A, which is crucial for fibrogenic signals like fibronectin 1 and SERPINE1 following TGFβ stimulation. The TGFβ-induced H3K9ac was mediated through SMAD signaling.

Summary: Long-term use of antiretroviral therapy (ART) may lead to comorbid conditions and even become a major cause of heart failure in people living with HIV. Our study found a significant increase in the expression of specific genes in cardiomyocytes treated with ARVs and in the cardiac tissue of HIV patients with a history of ART, which may be associated with cardiac toxicity, hypertrophy, and heart failure. Furthermore, we identified that the homeodomain-only protein homeobox (HOPX) plays a crucial role in ARVs-induced cellular hypertrophy through epigenetic regulation.

Summary: miR-15a-5p regulates MFN-2 and the compounds ES-37 and L-37 have a cardioprotective effect. They can attenuate oxidative stress and enhance anti-oxidative signaling mechanism to optimize cardiac hypertrophy response. The docking results show that ES-37 has greater binding affinity with the target proteins compared to L-37, with the highest binding values reported for MFN-2.

Summary: The study aimed to investigate the different effects of manipulating resistance training variables on muscle fiber cross-sectional area (fCSA) and associated molecular processes at both group and individual levels. The results showed that both the standard RT and variable RT increased fCSA and myonuclei domain size, while satellite cell (SC) and myonuclei content remained unchanged. Gene expression showed similar changes under both conditions, but acute MyoG expression was significantly higher in the variable RT group. Additionally, heatmap analysis revealed coupled changes in fCSA, SC, and myonuclei responses at the individual level.

Summary: A systematic review was conducted to analyze the effectiveness of patch augmentation in rotator cuff repair. The results showed that patch augmentation significantly reduced retear rate, alleviated pain, and improved shoulder rating scale. There was also a trend towards increased strength and decreased forward elevation range of motion. Further high-quality interventional studies are needed to confirm these findings.

Summary: This study assessed the association between the shortening of the iliopsoas and rectus femoris muscles, as measured by the modified Thomas test (MTT), and chronic low-back pain (CLBP) in resistance training practitioners. The results showed that reduced hip joint range of motion (ROM) may contribute to low-back pain, but this alone does not explain CLBP in both men and women.

Summary: This study aimed to compare the time course changes in DNA methylation and mRNA expression for selected myogenic regulatory factors immediately after, 4 h after, and 8 h after a single bout of resistance exercise, high-intensity interval exercise, and concurrent exercise. The results showed that the mean methylation across all CpGs analyzed was reduced after 4 and 8 h in response to all exercise protocols. In addition, all exercise bouts increased mRNA expression over time.

Summary: Acute exercise induces transcriptional changes that are essential for health, resilience, and performance adaptations. While moderate-intensity endurance training combined with conventional resistance training is commonly recommended, high-intensity training combining maximal-effort intervals with intensive resistance training may provide similar benefits. The mechanisms of these stimuli and their comparisons have not been fully understood.

Summary: Regular exercise has been recognized for centuries as a powerful stimulus to promote, maintain, and restore the healthy functioning of almost every physiological system in the human body. With advancing understanding of human physiology, evolving methodological possibilities, and an increasingly urgent public health situation, the study of exercise as a preventative or therapeutic treatment has become more interdisciplinary and impactful.
