Antitumor activity of RUNX3: Upregulation of E-cadherin and downregulation of the epithelial-mesenchymal transition in clear-cell renal cell carcinoma.

RUNX3 is a transcription factor and tumor suppressor that is silenced or inactivated in diverse tumors. The effect of RUNX3 on the epithelial-mesenchymal transition in clear-cell renal cell carcinoma (CCRCC) remains unclear. We determined the expression of RUNX3 and E-cadherin in tumor tissues and adjacent normal tissues of 30 CCRCC patients; established cultured CCRCC cells with the overexpression of RUNX3; and examined the in vivo tumorigenic function of RUNX3 in a nude mouse xenograft model of CCRCC. RUNX3 and E-cadherin were downregulated in human CCRCC samples. Cell lines with RUNX3 overexpression had reduced cell proliferation, invasion, and migration, a prolonged cell cycle, increased apoptosis, and increased expression of E-cadherin. In the nude mouse xenograft model of CCRCC, tumors with the overexpression of RUNX3 had smaller volumes and weights and had increased expression of E-cadherin. In conclusion, RUNX3 overexpression increased the level of E-cadherin and inhibited the proliferation, invasion, and migration of CCRCC in vitro and in vivo. RUNX3 has potential use as a biomarker for prognostic monitoring of CCRCC and as a therapeutic target for the treatment of this cancer.

Efficacy of anti-T-lymphocyte globulin-Fresenius as an induction agent in deceased-donor renal transplantation: A cohort study.

Anti-T-lymphocyte globulin (ATG) is frequently used in the induction regimen of renal transplantation, but its dose has not been standardized. In the present study, the efficacy of different ATG-Fresenius (ATG-F) doses was assessed in recipients of renal transplantation. A total of 131 adult recipients of renal transplantation who received ATG-F induction between August 2015 and July 2018 were included. The incidence of biopsy-confirmed acute rejection, graft function, as well as graft and patient survival within 12 months post-transplant, was assessed, and adverse events, including hematologic and infection-associated side effects, were compared between patients receiving a cumulative ATG-F dose of <7 or ≥7 mg/kg. The incidence of biopsy-confirmed acute rejection was similar between patients receiving cumulative doses of <7 and ≥7 mg/kg (7.5 vs. 4.7%, P=0.766). The incidence of infection within 12 months was lower in the ATG-F <7 mg/kg group compared with that in the ≥7 mg/kg group (26.9 vs. 50.0%, P=0.006), but the incidence of pneumonia did not differ between the ATG-F <7 and ≥7 mg/kg groups (10.4 vs. 20.3%, P=0.117). The incidence of urinary infection was higher in the ≥7 mg/kg group than in the <7 mg/kg group (20.4 vs. 7.46%, P=0.033), while the extent and duration of anemia and lymphopenia was similar between groups. There was no difference in graft function, delayed graft function, as well as overall and graft survival between the groups. In conclusion, a moderate reduction in the cumulative ATG-F dose was not associated with an increased risk of acute rejection, while the risk of infection was reduced. Optimization of the ATG-F dose for induction may facilitate the reduction of the risk of infection without compromising the induction efficacy in renal transplant recipients.

[Preoperative Lymphocyte-to-monocyte Ratio Predicts Prognosis in Patients with Stage T1 Non-muscle Invasive Bladder Cancer].

Objective To investigate the clinical value of preoperative lymphocyte-to-monocyte ratio(LMR)in evaluating the prognosis of patients with stage T1 non-muscle invasive bladder cancer(NMIBC).Methods A total of 215 patients with stage T1 NMIBC who underwent transurethral resection of bladder tumor were enrolled.Clinical data were collected.Patients were followed up and their disease-free survival(DFS)and overall survival(OS)were recorded.The receiver operating characteristic(ROC)curve of preoperative LMR in detecting patient prognosis was used to determine the optimal cut-off value for LMR.Patients were divided into low LMR group(LMR <3.86,n=77)and high LMR group(LMR ≥ 3.86,n=138).Kaplan-Meier survival curves were explored to compare cumulative DFS and OS rates in patients with different LMR levels,and COX proportional hazards regression model was used to analyze factors associated with DFS and OS.Results All these 215 patients with T1 stage NMIBC were followed up for 2-92 months,and the DFS rate was 59.07% and OS rate was 65.12%.Kaplan-Meier curves showed that the cumulative DFS rate(χ 2=4.784,P=0.029)and cumulative OS rate(χ 2=7.146, P=0.008)in the low LMR group were significantly lower than those in the high LMR group.Tumor size ≥ 3 cm(HR=1.398,95% CI:1.042-1.875,P=0.025),pathological grade G3(HR=1.266,95% CI:1.026-1.563,P=0.028),and LMR ≥ 3.86(HR=2.347,95% CI:1.080-5.101,P=0.031)were independent factors associated with DFS in patients with stage T1 NMIBC.In addition,tumor size ≥ 3 cm(HR=1.228,95% CI:1.015-1.484,P=0.034),pathological grade G3(HR=1.366,95% CI:1.017-1.834,P=0.038),and LMR<3.86(HR=2.008,95% CI:1.052-3.832,P=0.035)were independent factors associated with OS in patients with T1 stage NMIBC. Conclusion Preoperative LMR is an independent factor associated with patients' prognosis in T1 stage NIMBC.Patients with low LMR tend to have higher risk of NMIBC progression and death.
