Ponatinib exacerbate renal injury in systemic lupus erythematosus mouse model through PDGFR-PI3K/AKT pathway
Lupus nephritis (LN) is a common clinical complication of systemic lupus erythematosus (SLE). Proliferative lupus nephritis represents the gravest form of LN, and since effective drugs for its treatment are still lacking, tyrosine kinase inhibitors (TKIs) find extensive clinical utility due to their notable impact on suppressing cell proliferation and may serve as potential drugs for LN treatment. However, previous studies on the effects of TKI on LN have been controversial. Ponatinib, a third-generation TKI, lacks studies on its role in LN. This study aimed to investigate the impact of the ponatinib on LN. MRL/lpr mice were evaluated for renal function, autoimmune markers and histopathological changes after oral administration of ponatinib. RNA-seq analysis was performed to explore the molecular pathways involved in ponatinib-induced kidney injury. Ponatinib uniquely exacerbated renal damage in MRL/lpr mice, evidenced by a decline in renal function and acute pathological changes, without affecting lupus-related autoimmune markers. Differential expressed genes analysis and functional enrichment implicate ponatinib-induced renal damage in MRL/lpr mice associated with adiponectin. Furthermore, we verified ponatinib signaling the PI3K/AKT pathway through PDGFRα, potentially influencing high molecular weight adiponectin (HMW ADIPOQ) expression and exacerbating renal damage. In conclusion, this study demonstrates that ponatinib can up-regulate HMW ADIPOQ expression via the PI3K/AKT pathway by inhibiting PDGFRα phosphorylation, highlighting the potential nephrotoxic effects of ponatinib in lupus-prone mice, and underscoring the importance of monitoring renal function in systemic autoimmune diseases patients receiving ponatinib.
期刊介绍:
Biochemical Pharmacology publishes original research findings, Commentaries and review articles related to the elucidation of cellular and tissue function(s) at the biochemical and molecular levels, the modification of cellular phenotype(s) by genetic, transcriptional/translational or drug/compound-induced modifications, as well as the pharmacodynamics and pharmacokinetics of xenobiotics and drugs, the latter including both small molecules and biologics.
The journal''s target audience includes scientists engaged in the identification and study of the mechanisms of action of xenobiotics, biologics and drugs and in the drug discovery and development process.
All areas of cellular biology and cellular, tissue/organ and whole animal pharmacology fall within the scope of the journal. Drug classes covered include anti-infectives, anti-inflammatory agents, chemotherapeutics, cardiovascular, endocrinological, immunological, metabolic, neurological and psychiatric drugs, as well as research on drug metabolism and kinetics. While medicinal chemistry is a topic of complimentary interest, manuscripts in this area must contain sufficient biological data to characterize pharmacologically the compounds reported. Submissions describing work focused predominately on chemical synthesis and molecular modeling will not be considered for review.
While particular emphasis is placed on reporting the results of molecular and biochemical studies, research involving the use of tissue and animal models of human pathophysiology and toxicology is of interest to the extent that it helps define drug mechanisms of action, safety and efficacy.
