Overview of Gene Research
Zdhhc23, short for zinc finger DHHC-type palmitoyltransferase 23, is a key enzyme involved in protein palmitoylation, a post-translational modification. Protein palmitoylation plays a crucial role in diverse cellular processes such as immune regulation, lipid metabolism, and ion channel regulation [1,2,7]. It is associated with pathways like phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling, which are involved in cell growth, survival, and metabolism [4].
In hepatocellular carcinoma, Zdhhc23 mediates the palmitoylation of PHF2, enhancing its ubiquitin-dependent degradation. This disrupts the PHF2-mediated suppression of SREBP1c, a master lipogenesis transcription factor, thus remodeling lipid metabolism [1]. In the large yellow croaker, silencing of LczDHHC23 led to increased pro-inflammatory cytokine expression and decreased anti-inflammatory cytokines, highlighting its anti-inflammatory role in macrophage immune regulation [2]. In a neuropathic cancer pain model, upregulation of Zdhhc23 in spinal cord dorsal horn astrocytes led to increased GFAP palmitoylation and secretion of inflammatory factors, contributing to pain development [3]. In gliomas, inhibition of Zdhhc23 suppressed glioma-cell viability, autophagy, and promoted apoptosis, as well as weakened microglial migration [4]. In a gastric cancer model, Zdhhc23 mediated T-bet palmitoylation and promoted its degradation, inhibiting Th1 cell polarization and CD8+ T cell killing effect [5]. In a mouse model of INCL, reduced Zdhhc23 levels affected the S-palmitoylation of APT1, leading to microglia proliferation and neuroinflammation [6]. Also, Zdhhc23 controls the palmitoylation of the intracellular S0-S1 loop of BK channels, essential for their efficient cell surface expression [7].
In summary, Zdhhc23 is essential in multiple biological processes through its role in protein palmitoylation. Its study using various in vivo models, such as mouse models of cancer, immune-related diseases, and neurodegenerative conditions, has revealed its significance in disease-related processes like tumorigenesis, immune response dysregulation, and neuropathic pain development. Understanding Zdhhc23 function provides insights into potential therapeutic targets for these diseases.
