The effects of 30-min medium-intensity exercise on the expression of genes encoding heat shock protein 70 (HSPA1A) and its cochaperones HSP-70-binding protein 1 (HSPBP1) and Tag7 (PGLYRP1) in human leukocytes were studied. Transcription activities of HSPA1A and PGLYRP1 genes increased immediately after medium-intensity exercise, while activity of HSPBP1 gene remained unchanged. During recovery after exercise, the expression of HSPA1A gene virtually did not change, while the expression of PGLYRP1 gene continued to increase and after 90 min more than 2-fold surpassed the basal level.

Changes in DNA methylation and subsequent alterations in gene expression have opened a new direction in research related to the pathogenesis of peripheral neuropathic pain (PNP). This study aimed to reveal epigenetic perturbations underlying DNA methylation in the dorsal root ganglion (DRG) of rats with peripheral nerve injury in response to prior exercise and identify potential target genes involved. Male Sprague-Dawley rats were divided into three groups, namely, chronic constriction injury (CCI) of the sciatic nerve, CCI with prior 6-week swimming training (CCI_Ex), and sham operated (Sham).

Objectives: Exercise as a non-pharmacological intervention can exert beneficial effects directly through exosomes crossing the blood-brain barrier and reduce apoptosis after cerebral ischaemia/reperfusion injury (CI/RI). miRNA-124 (miR-124) is present in exosomes and plays an important role in regulating cerebral neurological activity; however, the mechanism of the relationship between exercise and the activity of exosomes and apoptosis after CI/RI remains unclear. Therefore, the present study investigated the effects of exercise preconditioning on cerebral ischemia/reperfusion injury from the perspective of exosomal miR-124 and apoptosis.

Friedreich's ataxia (FRDA) is a multisystem, autosomal recessive disorder caused by mutations in the frataxin () gene. As FRDA is considered an FXN deficiency disorder, numerous therapeutic approaches in development or clinical trials aim to supplement FXN or restore endogenous expression. These include gene therapy, protein supplementation, genome editing or upregulation of transcription.

Introduction: Binge Eating Disorder (BED) has high lifetime prevalence rates, low treatment success rates, and high rates of treatment dissatisfaction, early discontinuation of care, and recurrence. Complementary and integrative health (CIH) interventions (non-mainstream practices used with conventional approaches for whole-person treatment) hold potential to overcome many treatment barriers and improve BED treatment outcomes. Some CIH interventions have empirical support for use in eating disorders.

Exercise counters many adverse health effects of consuming a high-fat diet (HFD). However, complex molecular changes that occur in skeletal muscle in response to exercising while consuming a HFD are not yet known. We investigated the interplay between diverse exercise regimes and HFD consumption on the adaptation of skeletal muscle transcriptome.
