Semax peptide targets the μ opioid receptor gene Oprm1 to promote deubiquitination and functional recovery after spinal cord injury in female mice.

Background And Purpose: Lysosomal membrane permeabilization (LMP) is exacerbated following spinal cord injury (SCI), leading to increased neuronal cell death. Ubiquitination may affect LMP by regulating the stability and functionality of lysosomal membranes. Semax, a synthetic heptapeptide, comprising the ACTH (4-7) fragment and a C-terminal Pro-Gly-Pro tripeptide, exhibits neuroprotective properties and improves cognitive function.

Activation of the Nrf2 Signaling Pathway by Tetrahydroberberine Suppresses Ferroptosis and Enhances Functional Recovery Following Spinal Cord Injury.

Recent research has identified ferroptosis, a newly recognized form of programmed cell death, is a crucial factor in spinal cord injury (SCI). Tetrahydroberberine (THB) is a tetrahydroisoquinoline alkaloid derived from the tuber of the poppy family plant, Corydalis, which is recognized for its antioxidant and neuroprotective properties. Despite these attributes, the potential protective effects of THB against SCI are yet to be thoroughly investigated.

Vinpocetine protects against osteoarthritis by inhibiting ferroptosis and extracellular matrix degradation via activation of the Nrf2/GPX4 pathway.

Background: Osteoarthritis (OA) is a progressive joint condition marked by the slow degradation of articular cartilage. Vinpocetine (Vin), a synthetic derivative of vincamine derived from the vinca plant, exhibits anti-inflammatory and antioxidant properties. Nevertheless, the specific role and mechanism of Vin in the treatment of OA remain largely unexplored.

Ginsenoside-Rh2 Promotes Functional Recovery after Spinal Cord Injury by Enhancing TFEB-Mediated Autophagy.

: Following spinal cord injury (SCI), autophagy plays a positive role in neuronal protection, whereas pyroptosis triggers an inflammatory response. Ginsenoside-Rh2 (GRh2), known for its neuroprotective effects, is considered a promising drug. However, the exact molecular mechanisms underlying these protective effects remain unclear.

Sipeimine ameliorates osteoarthritis progression by suppression of NLRP3 inflammasome-mediated pyroptosis through inhibition of PI3K/AKT/NF-κB pathway: An in vitro and in vivo study.

Background: Osteoarthritis (OA) is a chronic and degenerative condition that persists and progresses over time. Sipeimine (Sip), a steroidal alkaloid derived from , has attracted considerable attention due to its exceptional anti-inflammatory, analgesic, antioxidant, and anti-cancer characteristics. However, Sip's effects on OA and its mechanism still need further research.
