Special Issue Information

Dear Colleagues,

Musculoskeletal diseases comprise numerous different disorders (more than 150 conditions) affecting the locomotor system (joints, bones, muscles, cartilage, meniscus and tendon tissues) and are associated with significant morbidity and disability. A recent analysis of the Global Burden of Disease estimated that approximately 1.71 billion people globally have musculoskeletal conditions. The number of affected individuals is expected to grow as the population ages. Thus, a better understanding of the etiology and new and more effective therapeutic treatments are needed. The purpose of this Special Issue is to report advances in pathophysiological mechanisms, predictive biomarkers and preclinical therapeutic approaches to musculoskeletal disorders, with a particular focus on bone cancers and osteoarthritis.

Authors are invited to contribute to this Special Issue with original research articles and comprehensive reviews.

Topics include, but are not limited to, the following:

  • Pathophysiological studies related to musculoskeletal diseases;
  • Molecular, biochemical and biomechanical mechanisms involved in the etiology and progression of musculoskeletal disorders;
  • Identification of biomarkers useful for early diagnosis and/or predictive of prognosis;

Preclinical research of potential drugs and cell-based strategies for the treatment of musculoskeletal disorders.

Muscle injuries often result in functional limitations due to insufficient healing. This study assessed the influence of calcitriol and vitamin D Receptor Modulator 2 (VDRM2) on muscle regeneration in male Wistar rats following open blunt muscle injury. The injured left soleus muscle of the rats was treated for the first four days after trauma with local injections of either calcitriol, VDRM2, or a 10% ethanol solution (control). Although muscle strength significantly decreased post-injury, all groups showed gradual improvement but did not achieve full recovery. By the 14th day, calcitriol-treated rats significantly outperformed the control group in the incomplete tetanic force, with VDRM2-treated rats showing muscle strength values that fell between the control and calcitriol groups. Similar trends were observed in complete tetanic contractions and were confirmed histologically via muscle cell width quantification. Additionally, histological analysis showed increased cellular turnover on the fourth postoperative day in the calcitriol group, as indicated by elevated cell proliferation rates and fewer apoptotic cells. VDRM2-treated animals showed only an increased proliferative activity on day 4 after injury. No noticeable differences between the groups for CAE-positive cells or visible muscle tissue area were found. In conclusion, predominantly calcitriol positively influenced post-trauma muscle recovery, where VDRM2 had substantially lower biological activity. Full article

In Duchenne muscular dystrophy (DMD), angiogenesis appears to be attenuated. Local administration of angiopoietin 1 (Ang1) has been shown to reduce inflammation, ischemia, and fibrosis in DMD mice. Ang1 is a vital vascular stabilizing factor that activates the endothelial cell receptor Tie2, leading to downstream pro-survival PI3K/Akt pathway activation and eNOS phosphorylation. In this study, we aimed to characterize the Ang/Tie2 signaling pathway within the diaphragm muscle of mouse models of DMD. Utilizing ELISA, immunoblots, and RT-qPCR, we demonstrated that Ang1 was downregulated, while the antagonist angiopoietin 2 (Ang2) was upregulated, leading to a decreased Ang1/Ang2 ratio. This correlated with a reduction in the phosphorylated Tie2/total Tie2 ratio. Interestingly, no significant differences in Akt or eNOS phosphorylation were observed, although DMD murine models did have elevated total Akt protein concentrations. These observations suggest that Ang1/Tie2 signaling may be dysregulated in the diaphragm muscle of DMD and further investigations may lead to new therapeutic interventions for DMD. Full article
