ObjectiveTo investigate the protective effect of genistein (Gen) on etoposide-induced chondrocyte senescence and its underlying mechanism. MethodsThe C28/I2 cell line was treated with different concentrations of Gen and etoposide, and the cell viability was detected by the CCK-8 assay. The senescence model of C28/I2 chondrocytes was induced by etoposide, with Gen intervention. Senescence-associated β-galactosidase (SA-β-gal) staining was performed to detect the senescence-positive rate and staining characteristics of chondrocytes. The expressions of peroxiredoxin 6 (Prdx6), cyclin-dependent kinaseto clarify the functional necessity of Prdx6. ResultsCompared with the etoposide group, the C28/I2 chondrocyte viability significantly increased (P<0.01), the expression ofsenescence-associated proteins p21 and p16 decreased (P<0.01, P<0.05), the expression of senescence-associated genes p21 and p16 reduced (both P<0.01), the fluorescence intensity of senescence-associated proteins p21 and p16 was diminished (P<0.05, P<0.01), and the proportion of SA-β-gal-positive cells decreased (P<0.01) in the Gen+etoposide group. Compared with the Control group, the expression of Prdx6 was downregulated in the etoposide group (P<0.05). Compared with the etoposide group, the expression of Prdx6 was upregulated in the Gen+etoposide group (P<0.01). Compared with the Control group, the GPx activity significantly decreased in the si-Prdx6 group (P<0.01). Furthermore, compared with the si-Prdx6 group, the GPx activity increased in the si-Prdx6+Gen group (P<0.05). Molecular docking results revealed that Gen formed hydrogen bond interactions with the active site of Prdx6. After Prdx6 knockdown, the expression of senescence-associated genes p21 and p16 and the fluorescence intensity of senescence-associated proteins p21 and p16 both increased in the Gen+etoposide+si-Prdx6 group (both P<0.01). ConclusionGen can inhibit etoposide-induced senescence of C28/I2 chondrocytes by upregulating the expression of Prdx6. This study provides potential drug targets and experimental basis for the prevention and treatment of chondrocyte senescence-related diseases.

Background/Aims:
Regorafenib is recommended by guidelines and trials as a sequential second-line therapy following progression on first-line sorafenib or lenvatinib in hepatocellular carcinoma (HCC). However, efficacy is limited, highlighting the urgent need to screen suitable patients and develop sensitization strategies.
Methods:
Acquired sorafenib- or lenvatinib-resistant (SR or LR) HCC cell lines and organoids were established. Genome-wide CRISPR library screen was performed in SR or LR cell strains to identify synthetic lethal targets of regorafenib. RNA-seq and FITC-regorafenib efflux assay were used to elucidate ERBB3-driven downstream signaling. Preclinical mouse models of cell line- and patient-derived xenografts and clinical cohorts of HCC patients were employed to validate the efficacy of ERBB3-guided patient stratification.
Results:
Screening with CRISPR library, we showed that inhibition of ERBB3 was synthetic lethal with regorafenib in SR or LR cell strains and organoids. Mechanistically, SR or LR triggered feedback activation of ERBB3 signaling and mediated regorafenib efflux via ERBB3-HIF1A-ABCB1 cascade pathway, limiting sensitivity to regorafenib. Moreover, ERBB3-low tumors following SR or LR exhibited significant sensitivity to regorafenib, suggesting its potential as a predictive biomarker to screen optimal candidates for sequential therapy. Seribantumab, an ERBB3-targeting monoclonal antibody, inhibited ERBB3-HIF1A-ABCB1 cascade, and its combination with regorafenib exerted marked synergistic anti-tumor effects on ERBB3-high tumors resistant to sorafenib or lenvatinib both in vitro and in vivo.
Conclusions
This study revealed that ERBB3 was a key resistance factor driving limited efficacy to sequential regorafenib, but also an effective therapeutic target whose inhibition enhanced regorafenib sensitivity after SR or LR.

Background:
Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality, characterized by poor prognosis due to its high proliferative and invasive potential. Tumor metabolic reprogramming, particularly involving glucose metabolism, is essential for tumor survival. This study investigates the role of the Hippo pathway effector transcriptional co-activator with PDZ-binding motif (TAZ) in regulating gluconeogenesis and promoting tumorigenesis in HCC.
Methods:
TAZ expression in HCC was analyzed using The Cancer Genome Atlas data and validated in clinical samples and cell lines. TAZ was overexpressed or silenced in HCC cell lines to evaluate its effects on cell proliferation, apoptosis, migration, and invasion. The expression and prognostic relevance of the gluconeogenesis-related genes phosphoenolpyruvate carboxykinase 1 (PCK1) and glucose-6-phosphatase (G6PC) were examined, along with their correlation with TAZ expression. Tumor growth was assessed in nude mice. Interactions between TAZ and the glucocorticoid receptor (GR) were investigated using co-immunoprecipitation, immunofluorescence, and chromatin immunoprecipitation assays.
Results:
TAZ was significantly upregulated in HCC tissues and cell lines. TAZ overexpression enhanced proliferation, reduced apoptosis, and promoted migration and invasion. In contrast, PCK1 and G6PC were downregulated in HCC and showed a negative correlation with TAZ expression.
Conclusion
TAZ modulates gluconeogenesis and accelerates tumor growth, whereas its knockdown attenuates tumor progression. TAZ interacts with GR, suppressing its transcriptional activity on gluconeogenic gene promoters.

PANoptosis, a newly defined form of cell death, is characterized by the simultaneous occurrence and crosstalk of apoptosis, pyroptosis, and necroptosis. It has emerged as a promising therapeutic target for various diseases. Ovarian dysfunction is marked by oligomenorrhea or amenorrhea, elevated gonadotropin levels, and diminished estrogen levels, often accompanying subfertility or infertility. Additionally, it can manifest with perimenopausal syndrome and increase the risks of osteoporosis, cardiovascular disease, and cognitive impairments, seriously impacting patients' quality of life. While current studies have reported that ovarian hypofunction is associated with apoptosis, pyroptosis, or necroptosis, a systematic investigation into the relationship between PANoptosis and ovarian hypofunction is still absent. This review aims to elucidate the potential link between these two phenomena, providing new insights into the mechanisms underlying ovarian hypofunction and potential treatment strategies.

Chinese Journal of Clinical Pharmacology and Therapeutics 2025;30(2):159-170
Cholangiocarcinoma(CCA)is a highly aggressive and heterogeneous biliary malignancy characterized by challenges in early diagnosis,limit-ed efficacy of traditional chemotherapy,and poor prognosis.Due to its significant heterogeneity at the genomic,epigenetic,and molecular levels,mo-lecular testing and targeted therapy have become increasingly important in CCA management,form-ing an integral part of the era of precision oncolo-gy.The development of next-generation sequenc-ing(NGS)has advanced research into the molecu-lar subtypes and therapeutic targets of CCA,includ-ing FGFR2 fusions/rearrangements,IDH1 muta-tions,and BRAF mutations.Recently,two phase Ⅲ clinical trials,TOPAZ-1 and KEYNOTE-966,have es-tablished the pivotal role of immunotherapy com-bined with chemotherapy in advanced CCA.While precision diagnosis and treatment in CCA have shown promising progress,this field remains in its exploratory phase and faces numerous challenges.This review summarizes recent advancements in the diagnosis,molecular targeted therapy,immuno-therapy,resistance mechanisms,and the develop-ment of novel strategies for CCA.

Objective::To examine the impact of hypertensive disorders of pregnancy (HDP) on offspring metabolomics.Methods::We searched five databases: PubMed, Ovid Embase, MEDLINE, Web of Science, and China National Knowledge Infrastructure, and included studies that reported metabolomics among human offspring born to HDP-complicated pregnancies.Results::Database search yielded 4054 articles, and after full-text screening, ten observational studies met inclusion criteria. Half of the studies had a sample size of less than 100 and were all observational studies in preeclampsia (PE) and gestational hypertension.Neonates were the most focused group in all included studies. Offspring born to HDP-complicated pregnancies exhibited statistically significant variations in blood metabolomics compared to their counterparts, characterized by amino acids, lipids, carnitine, and others (e.g., 1α,25-(OH) 2-D). Most studies reported a significant increase in differential metabolites of offspring born to HDP-complicated pregnancies. Four studies ( n = 1109) measured lipids-related metabolites, and all consistently showed that offspring born to PE-complicated pregnancies had significantly higher concentrations than non-PE exposed offspring. Conclusion::The existing evidence suggests an intergenerational effect of HDP on offspring metabolomics. Long-term follow-up studies are needed to advance the health effects of related adverse health outcomes and inform the prevention of offspring’s health.

Objective:To explore the potential profile characteristics of family health in patients with chronic diseases, analyze the influencing factors of different family health categories, and further investigate the relationship between family health categories and the quality of life in patients with chronic diseases, providing a scientific basis for targeted intervention strategies.Methods:This study was a cross-sectional survey. The data for the study were obtained from the Chinese Residents' Psychology and Behavior Survey Research Database. A multistage sampling method was employed to select 1 808 patients with chronic diseases as survey respondents from July to September 2021. Data were collected using the General Information Questionnaire, the Family Health Scale, and the European 5-Dimensional 5-Level Health Scale(EQ-5D-5L). Potential profiles of family health in patients with chronic diseases were identified using latent profile analysis. Univariate analysis and multiple Logistic regression were used to examine influencing factors, and generalized linear regression was performed to analyze the impact of different family health categories on quality of life.Results:A total of 1 808 chronic disease patients were enrolled, comprising 986 males and 822 females, with a age of (55.23 ± 7.02) years. The scores of family health, EQ-5D-5L, EuroQol Visual Analogue Scale were 38(34, 43), 0.94(0.84, 1.00), and 78(63, 87) points. The family health of patients with chronic diseases were categorized into three potential profiles: the low family health group (418 cases accounting for 23.1%), the medium family health group (747 cases accounting for 41.3%), and the high family health group (643 cases accounting for 35.6%). Multivariate Logistic regression analysis showed that family type, marital status, nature of household, education level, number of siblings and type of health insurance were significant factors influencing family health categories ( OR values were 0.464-2.503, all P<0.05). The family health was an important factor influencing quality of life ( χ2 values were 4.05-100.68, all P<0.05). Conclusions:There is significant heterogeneity in the family health of patients with chronic diseases, which can be divided into three distinct categories. Patients with higher family health levels have better quality of life. Medical professionals should develop precise intervention programs tailored to the characteristics of each category to improve family health levels and enhance the quality of life of patients with chronic diseases.
