Osmanlıoğlu HÖ, Nazıroğlu M. Resveratrol Modulates Diabetes-Induced Neuropathic Pain, Apoptosis, and Oxidative Neurotoxicity in Mice Through TRPV4 Channel Inhibition. Mol Neurobiol 2024; 61:7269-7286.

Abstract
Diabetic peripheral neuropathy (DPN) is caused by several factors, including reactive free oxygen radicals (ROS)-induced excessive Ca2+ influx. Transient receptor potential (TRP) vanilloid 4 (TRPV4) is a member of the Ca2+-permeable TRP superfamily. Resveratrol (RESV) has been extensively utilized in TRP channel regulation due to its pharmacological properties, which include antioxidant and TRP inhibitory effects. The protective function of RESV and the contribution of TRPV4 to streptozotocin (STZ)-induced neuropathic pain in mice are still unclear. Here, we evaluated the effects of RESV through the modulation of TRPV4 on Ca2+ influx, ROS-mediated pain, apoptosis, and oxidative damage in the mouse dorsal root ganglion (DRGs). From the 32 mice, four groups were induced: control, RESV, STZ, and STZ + RESV. We found that the injection of RESV reduced the changes caused by the STZ-induced stimulation of TRPV4, which in turn increased mechanical/thermal neuropathic pain, cytosolic Ca2+ influx, TRPV4 current density, oxidants (lipid peroxidation, mitochondrial ROS, and cytosolic ROS), and apoptotic markers (caspase-3, -8, and -9). The RESV injection also increased the STZ-mediated reduction of viability of DRG and the amounts of glutathione, glutathione peroxidase, vitamin A, β-carotene, and vitamin E in the brain, erythrocytes, plasma, liver, and kidney. All of these findings suggest that TRPV4 stimulation generates oxidative neurotoxicity, neuropathic pain, and apoptosis in the STZ-induced diabetic mice. On the other hand, neurotoxicity and apoptosis were reduced due to the downregulation of TRPV4 carried out through the RESV injection.

Abstract
The treatment of peripheral neuropathy resulting from diabetes primarily emphasizes neurotrophic medications. However, a growing body of clinical studies indicates that neuroinflammation plays a significant role in the pathogenesis of neuropathic pain. This has spurred active exploration of treatment strategies leveraging nanomedicine for diseases, aiming for superior therapeutic outcomes. In this context, we have developed biodegradable nanoparticles made of polylactic-co-glycolic acid, loaded with triptolide (pCel), designed to alleviate somatic cell neuropathic pain induced by diabetes. Treatment with pCel notably reduced levels of reactive oxygen species and apoptosis in vitro. Furthermore, the progression of streptozotocin-induced diabetes, characterized by elevated renal function indices (blood urea nitrogen, creatinine), liver function indices (bilirubin, alkaline phosphatase) and decreased levels of albumin and globulin, was mitigated following pCel administration. Importantly, oral treatment with pCel significantly inhibited mechanical allodynia and the activation of the sciatic glial cells in diabetic rats. These findings indicate that this synthetic, biodegradable nanomedicine exhibits excellent stability, biocompatibility and catalytic activity, making it a promising and innovative approach for the management of chronic pain conditions associated with diabetic neuropathy.

Effect of tetrahedral framework nucleic acids on the reconstruction of tendon-to-bone injuries after rotator cuff tears. Cell Prolif 2024; 57:e13605. [PMID: 38282322 DOI: 10.1111/cpr.13605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 12/16/2023] [Accepted: 01/09/2024] [Indexed: 01/30/2024] Open
Abstract
Clinicians and researchers have always faced challenges in performing surgery for rotator cuff tears (RCT) due to the intricate nature of the tendon-bone gradient and the limited long-term effectiveness. At the same time, the occurrence of an inflammatory microenvironment further aggravates tissue damage, which has a negative impact on the regeneration process of mesenchymal stem cells (MSCs) and eventually leads to the production of scar tissue. Tetrahedral framework nucleic acids (tFNAs), novel nanomaterials, have shown great potential in biomedicine due to their strong biocompatibility, excellent cellular internalisation ability, and unparalleled programmability. The objective of this research was to examine if tFNAs have a positive effect on regeneration after RCTs. Experiments conducted in a controlled environment demonstrated that tFNAs hindered the assembly of inflammasomes in macrophages, resulting in a decrease in the release of inflammatory factors. Next, tFNAs were shown to exert a protective effect on the osteogenic and chondrogenic differentiation of bone marrow MSCs under inflammatory conditions. The in vitro results also demonstrated the regulatory effect of tFNAs on tendon-related protein expression levels in tenocytes after inflammatory stimulation. Finally, intra-articular injection of tFNAs into a rat RCT model showed that tFNAs improved tendon-to-bone healing, suggesting that tFNAs may be promising tendon-to-bone protective agents for the treatment of RCTs.

J Nanobiotechnology 2024; 22:140.

Abstract
BACKGROUND Herbal nanoparticles are made from natural herbs/medicinal plants, their extracts, or a combination with other nanoparticle carriers. Compared to traditional herbs, herbal nanoparticles lead to improved bioavailability, enhanced stability, and reduced toxicity. Previous research indicates that herbal medicine nanomaterials are rapidly advancing and making significant progress; however, bibliometric analysis and knowledge mapping for herbal nanoparticles are currently lacking. We performed a bibliometric analysis by retrieving publications related to herbal nanoparticles from the Web of Science Core Collection (WoSCC) database spanning from 2004 to 2023. Data processing was performed using the R package Bibliometrix, VOSviewers, and CiteSpace. RESULTS In total, 1876 articles related to herbal nanoparticles were identified, originating from various countries, with China being the primary contributing country. The number of publications in this field increases annually. Beijing University of Chinese Medicine, Shanghai University of Traditional Chinese Medicine, and Saveetha University in India are prominent research institutions in this domain. The Journal "International Journal of Nanomedicine" has the highest number of publications. The number of authors of these publications reached 8234, with Yan Zhao, Yue Zhang, and Huihua Qu being the most prolific authors and Yan Zhao being the most frequently cited author. "Traditional Chinese medicine," "drug delivery," and "green synthesis" are the main research focal points. Themes such as "green synthesis," "curcumin," "wound healing," "drug delivery," and "carbon dots" may represent emerging research areas. CONCLUSIONS Our study findings assist in identifying the latest research frontiers and hot topics, providing valuable references for scholars investigating the role of nanotechnology in herbal medicine.
