Porcupine (PORCN) is a membrane-bound O-acyltransferase primarily localized in the endoplasmic reticulum, where it catalyzes the palmitoylation of Wnt proteins-a critical post-translational modification required for their secretion and signal transduction. This lipid modification plays a key role in regulating essential cellular processes such as differentiation, proliferation, migration, and apoptosis. Inhibition of PORCN prevents Wnt palmitoylation, thereby blocking its extracellular transport and downstream signaling, including β-catenin production, which ultimately suppresses aberrant cell growth.

Protein kinases are key regulators of cellular signaling, metabolism, and essential functions, acting as molecular switches through phosphorylation. Their dysregulation is implicated in a wide range of pathologies, including cancer and autoimmune disorders, making them attractive therapeutic targets. PKN3, a serine-threonine kinase of the AGC family within the protein kinase N (PKN) subfamily (PKN1-3), plays a critical role in cytoskeletal dynamics and gene [expression through its interactions with Rho GTPases.

UBC13 is an E2 ubiquitin coupling enzyme, which interacts with different E3 ligases and exerts ubiquitination activity to assemble and synthesize lysine-63-linked (Lys63) ubiquitin strands, thus playing an important role in cell homeostasis, various diseases caused by inflammation, and the occurrence and development of cancer. In this paper, we review the structure and function of UBC13, summarize the diverse pathways it mediates, and discuss its involvement in bacterial and non-bacterial inflammatory diseases.

Interleukin-33 (IL-33) is a nuclear factor and member of the IL-1 cytokine family. IL-33 is mainly expressed by epithelial and endothelial cells and exerts its function through interaction with various immune cells, and binding to its receptor can form the IL-33/Suppression of tumorigenicity 2 (ST2) signaling pathway. While most cytokines are actively synthesized within cells, IL-33 is produced passively in response to tissue damage or cell necrosis, indicating its role as a signaling molecule following cellular infection, stress, or trauma.

In the last decade, research has clarified the binding interactions between immunoglobulin E (IgE) and its high-affinity receptor, the FcεRI alpha chain (FcεRI). The formation of the IgE-FcεRI complex is crucial in the context of atopic allergies, linking allergen recognition to cellular activation and disease manifestation. Consequently, pharmacological strategies that disrupt these interactions are vital for managing atopic conditions.

Jumonji domain-containing protein D3 (JMJD3) is a 2-oxoglutarate-dependent dioxygenase that specifically removes transcriptional repression marks di- and tri-methylated groups from lysine 27 on histone 3 (H3K27me2/3). The erasure of these marks leads to the activation of some associated genes, thereby influencing various biological processes, such as development, differentiation, and immune response. However, comprehensive descriptions regarding the relationship between JMJD3 and inflammation are lacking.

Breast cancer (BC) is the most frequent malignant cancer diagnosis and is a primary factor for cancer deaths in women. The clinical subtypes of BC include estrogen receptor (ER) positive, progesterone receptor (PR) positive, human epidermal growth factor receptor 2 (HER2) positive, and triple-negative BC (TNBC). Based on the stages and subtypes of BC, various treatment methods are available with variations in the rates of progression-free disease and overall survival of patients.

Perovskite solar cells (PSCs) are among the most promising photovoltaic technologies owing to their exceptional optoelectronic properties. However, the lower efficiency, poor stability and reproducibility issues of large-area PSCs compared with laboratory-scale PSCs are notable drawbacks that hinder their commercialization. Here we report a synergistic dopant-additive combination strategy using methylammonium chloride (MACl) as the dopant and a Lewis-basic ionic-liquid additive, 1,3-bis(cyanomethyl)imidazolium chloride ([Bcmim]Cl).

Although rhabdovirus (MSRV) causes serious fish epidemics worldwide, the detailed mechanism of MSRV entry into host cells remains unknown. Here, we comprehensively investigated the mechanism of MSRV entry into epithelioma (EPC) cells. This study demonstrated that MSRV enters EPC cells via a low pH, dynamin-dependent, microtubule-dependent, and clathrin-mediated endocytosis.
