Overexpression or siRNA of IGF-1 in primary human uterine leiomyoma cells were treated with or without mifepristone. MTT was used to evaluate cell viability in assays of cell proliferation and cytotoxicity. IGF-1 expression in the cells was measured with real-time RT-PCR and Western blotting and manipulated with lentivirus ectopic overexpression or siRNA silencing.Results: Inhibition of cell viability by mifepristone was found dependent on drug concentration and treatment time. IGF-1 and phosphorylation-ERK1/2 expression were decreased, while phosphorylation-AKT expression was increased after mifepristone treatment. IGF-1 significantly promoted cell growth, while IGF-1 knockdown and mifepristone showed synergistic inhibition effects on cell growth. The overexpression of IGF-1 reversed the inhibition of cell growth and ERK1/2 phosphorylation but showed no effect on AKT phosphorylation.Conclusion: Our study for the first time demonstrated that IGF-1 signaling via ERK1/2 appears to be an important target of mifepristone in the treatment of uterine leiomyomas, which may provide a new approach to avoid leiomyoma re-growth after cessation of mifepristone.Keywords: uterine leiomyomas, mifepristone, IGF-1, signal pathway

This study aims to clarify the prognostic factors of cervical cancer patients aged ≥ 65.Patient and Methods: The incidences and characteristics of patients diagnosed with cervical cancer (aged ≥ 65 and < 65) during 2004– 2015 were obtained through the Surveillance, Epidemiology, and End Results Program (SEER) database. The differences of distributions of characteristics between two age groups were compared by chi-squared (χ2) test. Kaplan–Meier survival method, Log-rank test, Cox-regression and visual nomogram were utilized for survival analysis.Results: The annual incidences of two age groups with cervical cancer were (5.5– 7.5)/100,000 and (3.4– 3.9)/100,000, respectively, during 2004– 2015. The 1-year and 5-year cancer-specific survival rates of old patients were both lower than those of young patients (P < 0.001). The proportions of unmarried state and advanced International Federation of Gynecology and Obstetrics (FIGO) stage in old patients were higher than those in relatively young patients, and fewer elderly patients received surgery. Univariate and multivariate survival analysis showed non-squamous cell carcinoma, poor differentiation and late FIGO stage were independent poor prognostic factors for patients aged ≥ 65. Treatments improved the outcomes of elderly patients, and the effect of surgery was better than non-surgical treatment on elderly patients with FIGO I. Besides, geriatric score and survival probability could be accomplished by our nomogram with a c-index of 0.7945.Conclusion: Delayed diagnosis and insufficient treatment were two distinct features of elderly patients and correlated with their poor clinical outcomes. More attention and active treatments should be adopted in elderly women based on their general condition.Keywords: cervical cancer, elderly, database analysis, prognosis

Abstract

The vacuolar-type H+-ATPase (V-ATPase) is essential for many cell processes. Our previous study has demonstrated that Tfp1 is a putative subunit of V-ATPase, loss of which causes disorders in calcium homeostasis and decreased resistance to oxidative stress. In this study, we found that further deletion of PMC1, a vacuolar calcium pump, in tfp1∆/∆ mutant led to more severe dysregulation of calcium homeostasis. Besides, the tfp1∆/∆pmc1∆/∆ mutant was more sensitive to H2O2 and had a higher ROS level. As is known, V-ATPase mutants are sensitive to NaCl, and PMC1 mutant is resistant against NaCl. However, the tfp1∆/∆pmc1∆/∆ mutant exhibited sensitivity to NaCl. Mechanism study demonstrated that their sensitivity was associated with reduced osmotic resistance caused by relatively low expression of GPD1. In addition, we first found that NaCl addition significantly declined ROS levels in tfp1∆/∆ and tfp1∆/∆pmc1∆/∆ mutants. In tfp1∆/∆ mutant, decreased ROS levels were relevant to enhanced antioxidant activities. However, in tfp1∆/∆pmc1∆/∆ mutant, reduced ROS resulted from decreased total calcium content, revealing that NaCl affected ROS levels in the two mutants through different mechanisms. Taken together, our data indicated that loss of both TFP1 and PMC1 further affected calcium homeostasis and other cellular processes in Candida albicans and provides a potential antifungal target.

Abstract

Background: The Shurui® system (SR-ENS-600) is a novel fully integrated single-port robotic system with bioinspired serpentine surgical manipulators and a camera., Methods: This was a single-centre prospective case-series study according to the IDEAL stage 2a guidelines to evaluate the feasibility, safety and potential efficacy of the Shurui® system for gynaecological surgeries and to improve the operating process., Results: Ten patients with a gradient of surgical difficulty who had indications for laparoscopic surgery and who volunteered to participate in a clinical trial were enrolled in the study. All 10 subjects successfully completed the procedure without converting to other procedures. No serious complications were reported at the 3-month follow-up. Subjects recover faster after surgery and are highly satisfied with the incision., Conclusions: Gynaecological single-site laparoscopic surgery with the Shurui® system was technically feasible for well-selected patients with minimal alterations in technique. Further prospective multicenter large-sample studies are necessary., Registration Number: ChiCTR2300075431. URL: https://www.chictr.org.cn/showproj.html?proj=189995., (© 2024 John Wiley & Sons Ltd.)
