Background: Pursuing excellence in healthcare delivery systems is an ongoing process. In this process, continuing medical education (CME) is essential for medical professionals to maintain high standards of patient care. In China, where the healthcare sector is undergoing considerable reforms and faces challenges owing to socioeconomic development and demographic shifts, an effective CME system is vital for general practitioners (GPs).

PIK3CA, which encodes protein p110α, is one of the most frequently mutated oncogenes and a promising drug-target for human cancer. Previously, we demonstrate that p85β is released from PI3K complex which contain PIK3CA helical domain mutations and translocates into nucleus to regulate tri-methylation of H3K27, thereby promoting tumorigenicity. Here, we identify DIRAS2 and SOWAHB as target genes of nuclear p85β in PIK3CA-helical-domain-mutant tumors.

While ubiquitin ligases have been extensively studied, research on the reverse process of ubiquitination, particularly the mechanisms involving USP1, remains relatively limited. USP1 is overexpressed in various cancers, influencing tumor initiation and progression by regulating multiple associated proteins.

Methods: The primary components of PTQF were characterized using UHPLC-Q-TOF-MS/MS. The identified compounds subsequently employed network pharmacology to predict the signaling pathways associated with the inflammatory phase of POI.
