Objective:To investigate the expression of heat shock factor binding protein 1 (HSPB1) in endometrial carcinoma and its clinical significance.Methods:The pan-cancer dataset after standardization and unification was downloaded from the University of California Santa Cruz (UCSC) Genome database (updated to December 6, 2019), and the expression of HSPB1 in pan-cancer was analyzed. The transcriptome data of endometrial carcinoma of the uterus from the Cancer Genome Atlas (TCGA) database were downloaded (updated to July 21, 2016), including 552 cases of endometrial carcinoma and 35 cases of corresponding adjacent tissue samples. The clinical data of 543 patients with endometrial cancer were obtained. The differences in the expression levels of HSPB1 in patients with different clinicopathological features were compared. R 4.3.1 software maxstat was used to calculate the optimal critical value (>46.30) of HSPB1 expression, and the patients were divided into HSPB1 low expression group (<46.30) and HSPB1 high expression group (≥46.30). Kaplan-Meier method was used to analyze the difference in prognosis between the 2 groups, and log-rank test was performed. The top 50 genes with positive and negative correlation with HSPB1 were screened by LinkedOmics database. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed on HSPB1. The interaction network of HSPB1 protein was analyzed by STRING database and Cytoscape 3.9.1 software. The correlation between HSPB1 expression and various immune cell infiltration levels was analyzed by using the TIMER2.0 database.Results:The expression of HSPB1 in 27 kinds of tumor tissues was higher than that in paracancerous tissues, and the expression of HSPB1 in 2 kinds of tumor tissues was lower than that in paracancerous tissues (all P < 0.05). In the transcriptome data of 552 cases of endometrial cancer and 35 cases of corresponding paracancerous tissues in the TCGA database, the relative expression level of HSPB1 in endometrial cancer tissues was higher than that in corresponding paracancerous tissues ( t = -2.90, P = 0.005). The result of the comparison of relative expression level of HSPB1 in endometrial cancer patients with different clinicopathological features showed that patients aged < 65 years had higher expression level compared to those aged ≥ 65 years, patients at clinical stage Ⅰ-Ⅱ had higher expression level compared to those at stage Ⅲ-Ⅳ, patients with Grade grading G 1-G 2 had higher expression level compared to those with G 3, and patients with pathological type I had higher expression level compared to those with type Ⅱ (all P < 0.05). Of the 543 patients, 2 were lost to follow-up, and the overall survival of the remaining 541 patients with high HSPB1 expression was better than that of those with the low expression ( HR = 0.532, 95% CI: 0.333-0.849, P = 0.008). HSPB1 and its related genes were mainly involved in estrogen signaling, p53 signaling and other pathways; HSPB1 was involved in cysteine-type endopeptidase inhibitor activity and calcium-dependent protein binding. The top 10 genes with the strongest correlation with HSPB1 in protein-protein interaction analysis were DSG3, EVPL, PKP1, DSC3, PKP3, PPL, KRT5, IVL, TGM1 and CSTA. The expression of HSPB1 was negatively correlated with tumor purity ( r = -0.025, P < 0.01), and positively correlated with CD4 + T cells ( r = 0.204, P < 0.01), CD8 + T cells ( r = 0.225, P < 0.01), B cells ( r = 0.285, P < 0.01), NK cells ( r = 0.269, P < 0.01), macrophages ( r = 0.234, P < 0.01) and dendritic cells ( r = 0.354, P < 0.01). Conclusions:The high expression of HSPB1 is associated with clinicopathological features, prognosis and immune infiltration in patients with endometrial carcinoma. It may be one of the reference indexes for predicting the prognosis of patients with endometrial cancer.

AIM:To investigate the potential effect of Dabuyuan Jian(DBYJ)on peroxisome proliferator-acti-vated receptor γ(PPARγ)/nuclear factor-κB(NF-κB)signaling pathway and related inflammatory proteins in mice with mild cognitive impairment(MCI),and to explore the mechanism of DBYJ in improving the learning and memory ability of MCI mice.METHODS:Forty C57BL/6 male mice were randomly divided into 5 groups,including negative control(NC)group,D-galactose(D-Gal)group,D-Gal+DBYJ group,D-Gal+GW9662(PPARγ inhibitor)group and D-Gal+GW9662+DBYJ group,with 8 mice each.The mice in NC group were subcutaneously injected with 0.9%saline solution on the back of the neck for 8 weeks,while those in the remaining 4 groups were subcutaneously injected with D-Gal(100 mg·kg-1·d-1)on the back of the neck for 8 weeks to establish the MCI model.From week 5 to week 8,the mice in D-Gal+GW9662 and D-Gal+DBYJ+GW9662 groups were intraperitoneally injected with GW9662(1 mg·kg-1·d-1).From week 5,the mice in D-Gal+DBYJ and D-Gal+DBYJ+GW9662 groups were treated with DBYJ(13.2 g/kg)by gavage,while those in the re-maining 3 groups were administered an equal volume of purified water for 4 weeks.The Morris water maze(including posi-tioning navigation experiment and space exploration experiment)was used to assess the learning and memory ability of the mice.The structural integrity of the hippocampus of the mice was assessed by hematoxylin-eosin(HE)staining.Nissl staining was used to evaluate damage to hippocampal neurons in mice,and Western blot was applied to detect the protein levels of interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α),PPARγ,P65 and phosphorylated P65(p-P65)in the hippocampus of the mice.RESULTS:Compared with NC group,the escape latency of the mice in D-Gal+D-Gal and D-Gal+GW9662 groups significantly increased(P＜0.01),while the number of platform crossing and the duration of staying in the target quadrant within 60 s significantly decreased(P＜0.01).The number of neurons in the CA3 region remarkably decreased(P＜0.01),and pyramidal cell disarrangement and neuronal shrinkage were observed.The levels of TNF-α,IL-1β and p-P65 were up-regulated,while the expression of PPARγ was down-regulated(P＜0.05).Compared with D-Gal group,the escape latency of the mice in D-Gal+DBYJ group significantly decreased(P＜0.01),while the number of plat-form crossing and the duration of staying in the target quadrant within 60 s remarkably increased(P＜0.01).The number of neurons in the CA3 region increased(P＜0.01),the pyramidal cells were more neatly arranged,and the cytoarchitec-ture was intact.The levels of TNF-α,IL-1β and p-P65 were down-regulated,while the expression of PPARγ was up-regu-lated(P＜0.05).Compared with D-Gal+GW9662 group,significantly decreased escape latency was observed in D-Gal+DBYJ+GW9662 group(P＜0.01),and the number of platform crossing and the duration of staying in the target quadrant within 60 s remarkably increased(P＜0.05).The number of neurons in the CA3 region increased(P＜0.01),the pyrami-dal cells were arranged more neatly,and the cytoarchitecture was relatively intact.The levels of TNF-α,IL-1β and p-P65 were down-regulated,while the expression of PPARγ was up-regulated(P＜0.05).The effects shown in D-Gal+DBYJ+GW9662 group were inferior to those in D-Gal+DBYJ group,indicating that the therapeutic effect of DBYJ was inhibited after the addition of GW9662.CONCLUSION:Dabuyuan Jian improves the learning and memory ability of MCI mice,and the mechanism may be related to the expression of key proteins in the PPARγ/NF-κB signaling pathway.
