Background: Studies suggest that brain-derived neurotrophic factor (BDNF) exerts effects on the neuronal function of hippocampal neurons and increases hippocampal mitogen-activated protein kinase phosphatase-1 (MKP-1) expression, which causes depressive behaviors in rat or mouse. Here we focus on the change of serum MKP-1, BDNF, testosterone (T), and estradiol (E 2 ) levels, in order to test the hypothesis that dysregulation of MKP-1, BDNF, T, and E 2 are associated with depression in perimenopausal women. Methods: Women with depression, after meeting criteria in the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, for mental and behaviural disorders and the 17-item Hamilton Depression Rating Scale (HDRS), were included in the study. Psychosocial data and blood samples were obtained from the subjects in the study, including 38 perimenopausal and 32 young women with depression, 26 healthy control perimenopausal women, and 34 young women. Results: Serum MKP-1 levels were higher and T was lower in the women with depression compared to controls ( p < 0.05), and depressed perimenopausal women exhibited the highest serum MKP-1 levels and lowest T levels. Logistic regression analyses showed that MKP-1 levels were positively correlated with HDRS scores in the women, and T levels were inversely correlated with HDRS scores in the perimenopausal women ( p < 0.05).Conclusions: This study suggests that high serum MKP-1 levels are associated with depression in women, and this association did not appear to be confounded by age. Further, the results provide evidence of association between depressive symptom severity and increasing serum MKP-1 levels in women, and decreasing T levels in perimenopausal women.
Background PDZ-binding kinase (PBK) encodes a serine/threonine protein kinase related to the dual specific mitogen-activated protein kinase kinase (MAPKK) family. There is evidence that overexpression of this gene is associated with tumorigenesis. However, the role of PBK in hepatocellular carcinoma (HCC) remains unclear. Therefore, we evaluated the prognostic role of PBK and its correlation with immune infiltrates in hepatocellular carcinoma. Methods The expression of PBK in pan-cancers was studied by Onconmine and TIMER. The expression of PBK in HCC patients and its relationship with clinicopathological characteristics were analyzed using The Gene Expression Profiling Interactive Analysis (GEPIA), The human protein atlas database (HPA), The Cancer Genome Atlas (TCGA), and Gene Expression Omnibus (GEO) databases. Receiver operating characteristic (ROC) curve was used to determine the diagnostic value of PBK in HCC patients. The relationship between PBK and prognosis of HCC was performed by GEPIA and Kaplan Meier plotter web tool. The correlations between the clinical characteristics and overall survival were analyzed by Univariate Cox regression and Multivariate Cox hazards regression to identify possible prognostic factors for HCC patients. LinkedOmics was applied to investigate co-expression associated with PBK and to analyze Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. The network map of PBK and related genes is constructed by GeneMANIA. Finally, TIMER and TISIDB were used to analyze the correlations between PBK and tumor-infiltrating immune cells. Results Multiple database analysis shows that PBK was highly expressed in many types of tumors, including hepatocellular carcinoma, and was significantly related to tumor stage (P=0.0089), age (P=0.0131), and race (P=0.0024) of HCC patients. The receiver operating characteristic (ROC) curve analysis showed that PBK had high diagnostic potential to HCC in GSE76427 (AUC=0.8799), GSE121248 (AUC=0.9224), GSE62232 (AUC=0.9975), and GSE84402 (AUC=0.9541). Multivariate Cox hazards regression showed that high expression of PBK may be an independent risk factor for overall survival in HCC patients (HR = 1.566, 95% CI=1.062–2.311, P= 0.024). The Protein–protein interaction network showed that PBK significantly interacted with LRRC47, ARAF, LGALS9B, TTK, DLG1, and other essential genes. Furthermore, enrichment analysis showed that PBK and co-expressed genes participated in many biological processes, cell composition, molecular functions, and pathways in HCC. Finally, the immune infiltration analysis by TIMER and TISIDB indicated that a significant tightly correlation between PBK and macrophages, neutrophils, as well as chemokines and receptors. Conclusions High expression of PBK is significantly correlated with poor survival and immune infiltrates in hepatocellular carcinoma. Our study suggests that PBK can be used as a biomarker of poor prognosis and potential immune therapy target in hepatocellular carcinoma.
Von Hippel-Lindau (VHL) disease is a rare, autosomal inherited tumor disorder caused by mutations or deletions of the VHL gene. Most of the previous research focused on the clinical features and molecular mechanisms of the disease, few concerned about the psychosocial impact on the patients and their family. We encountered a VHL family in the clinical work and attempted to assess the possible psychological effects of the disease on the members of the family. Three questionnaires including Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Revised Symptom Checklist (SCL-90-R) were used in the research.

The receiver operating characteristic (ROC) curve analysis from 4 GEO databases showed that PBK is a predictive marker for HCC. Moreover, high expression of PBK correlated with poor prognosis. Multivariate Cox hazards regression showed that high expression of PBK may be an independent risk factor for overall survival in HCC patients (HR = 1.566, 95% CI=1.062-2.311, P= 0.024). The Protein–protein interaction network showed that PBK significantly interacted with LRRC47, ARAF, LGALS9B, TTK, MELK and other essential genes. Furthermore, enrichment analysis showed that PBK and co-expressed genes participated in many biological processes, cell composition, molecular functions and pathways in HCC. Finally, the immune infiltration analysis by TIMER and TISIDB indicated that PBK expression tightly correlated with the infiltration of tumor-infiltrating lymphocytes (TILs), chemokines, and receptors.ConclusionsHigh expression of PBK is significantly correlated with poor survival and immune infiltrates in hepatocellular carcinoma. Our study suggests that PBK can be used as a biomarker of poor prognosis and potential immune therapy target in hepatocellular carcinoma.
