Abstract
Studies have confirmed that P2 purinergic receptors (P2X receptors and P2Y receptors) expressed in gastric cancer (GC) cells and GC tissues and correlates with their function. Endogenous nucleotides including ATP, ADP, UTP, and UDP, as P2 purinergic receptors activators, participate in P2 purinergic signal transduction pathway. These activated P2 purinergic receptors regulate the progression of GC mainly by mediating ion channels and intracellular signal cascades. It is worth noting that there is a difference in the expression of P2 purinergic receptors in GC, which may play different roles in the progression of GC as a tumor promoting factor or a tumor suppressor factor. Among them, P2 × 7, P2Y2 and P2Y6 receptors have certain clinical significance in patients with GC and may be used as biological molecular markers for the prediction of patients with GC. Therefore, in this paper, we discuss the functional role of nucleotide / P2 purinergic receptors signal axis in regulating the progression of GC and that these P2 purinergic receptors may be used as potential molecular targets for the prevention and treatment of GC.

Wei C, Fu M, Zhang H, Yao B. How is the P2X7 receptor signaling pathway involved in epileptogenesis? Neurochem Int 2024; 173:105675.

Abstract
Epilepsy, a condition characterized by spontaneous recurrent epileptic seizures, is among the most prevalent neurological disorders. This disorder is estimated to affect approximately 70 million people worldwide. Although antiseizure medications are considered the first-line treatments for epilepsy, most of the available antiepileptic drugs are not effective in nearly one-third of patients. This calls for the development of more effective drugs. Evidence from animal models and epilepsy patients suggests that strategies that interfere with the P2X7 receptor by binding to adenosine triphosphate (ATP) are potential treatments for this patient population. This review describes the role of the P2X7 receptor signaling pathways in epileptogenesis. We highlight the genes, purinergic signaling, Pannexin1, glutamatergic signaling, adenosine kinase, calcium signaling, and inflammatory response factors involved in the process, and conclude with a synopsis of these key connections. By unraveling the intricate interplay between P2X7 receptors and epileptogenesis, this review provides ideas for designing potent clinical therapies that will revolutionize both prevention and treatment for epileptic patients.

Abstract
Ginseng is frequently used in traditional Chinese medicine to treat neurological disorders. The primary active component of ginseng is ginsenoside, which has been classified into more than 110 types based on their chemical structures. Ginsenoside Rb1 (GsRb1)-a protopanaxadiol saponin and a typical ginseng component-exhibits anti-inflammatory, anti-oxidant, anti-apoptotic, and anti-autophagy properties in the nervous system. Neurological disorders remain a leading cause of death and disability globally. GsRb1 effectively treats neurological disorders. To contribute novel insights to the understanding and treatment of neurological disorders, we present a comprehensive review of the pharmacokinetics, actions, mechanisms, and research development of GsRb1 in neurological disorders.

Activation of P2X4 receptors in midbrain cerebrospinal fluid-contacting nucleus leads to mechanical hyperalgesia in chronic constriction injury rats. Purinergic Signal 2023; 19:481-487. [PMID: 36529845 PMCID: PMC10539240 DOI: 10.1007/s11302-022-09911-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 11/26/2022] [Indexed: 12/23/2022] Open
Abstract
Neuropathic pain is a refractory pain state, and its mechanism is still not clear. Previous studies have shown that the purine receptor P2X4R expressed on hyperactive microglia in the spinal cord is essential for the occurrence and development of neuropathic pain. The cerebrospinal fluid-contacting nucleus (CSF-contacting nucleus) in the midbrain has been found to play an important role in the descending inhibition system of modulation. However, there have been no studies on P2X4R in the CSF-contacting nucleus involved in neuropathic pain. To investigate whether P2X4R is expressed in the CSF-contacting nucleus and whether its expression in the CSF-contacting nucleus is involved in the regulation of neuropathic pain, we used a model of chronic sciatic nerve ligation injury (CCI) to simulate neuropathic pain conditions. Immunohistochemistry experiments were conducted to identify the expression of P2X4R in the CSF-contacting nuclei in CCI rats, and western blot analysis showed a significant increase in P2X4R levels 7 days after modeling. Then, we packaged a P2rx4 gene-targeting shRNA in scAAV9 to knock down the P2X4R level in the CSF-contacting nucleus, and we found that CCI-induced mechanical hyperalgesia was reversed. In conclusion, P2X4R expressed in the CSF-contacting nucleus is involved in the process of neuropathic pain, and downregulating P2X4R protein in the CSF-contacting nucleus can reverse the occurrence and development of hyperalgesia, which could represent a potent therapeutic strategy for neuropathic pain.
