Abstract
As a gynecological malignancy, endometrial cancer (EC) has a high incidence and mortality rate in women. The aim of the present study was to investigate the mechanism of EC and to identify novel effective treatment methods for this disease. The viability and proliferation of the RL95-2 human endometrial cancer cell line were assessed using Cell Counting Kit-8 assays. Colony formation, wound healing, Transwell, TUNEL and immunofluorescence assays were used to assess the effects of 5, 10 and 15 mM lidocaine on the colony formation, migration, invasiveness, apoptosis and Beclin 1 protein expression of RL95-2 cells, respectively. Furthermore, western blotting was used to analyze the protein expression levels of apoptosis- and autophagy-related proteins. The results demonstrated that lidocaine inhibited the viability, proliferation and migration of EC cells, and promoted apoptosis. Furthermore, lidocaine was demonstrated to induce autophagy and Beclin 1 protein expression in EC cells. In conclusion, lidocaine inhibited the proliferation and migration of EC cells, and promoted apoptosis via autophagy induction, which indicated that lidocaine may be a potential therapeutic drug for the treatment of EC.

[PMID: 31644605 PMCID: PMC6808552 DOI: 10.1371/journal.pone.0224285] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Accepted: 10/09/2019] [Indexed: 11/18/2022] Open
Abstract
Background Intranasal lidocaine has been shown to be effective in treating patients with acute migraines; however, its efficacy is still controversial. In this study, we intend to assess the efficacy and safety of intranasal lidocaine compared with a placebo or an active comparator for the treatment of migraines. Method PubMed, EMBASE, Cochrane library, and Scopus databases were searched from their inceptions to November 2018. Randomized controlled studies investigating the efficacy of intranasal lidocaine compared with a placebo or an active comparator were selected. Two reviewers independently extracted and synthesized data using a random-effects model. The primary outcome was pain intensity. The secondary outcomes were success rate, the need for rescue medicine, and relapse occurrences. We registered the study at PROSPERO with an ID of CRD42018116226. Results Six studies (n = 613) were eligible for the meta-analysis. Overall, the results revealed that the study population who was administered intranasal lidocaine had a lower pain intensity at 5 min (standardized mean difference (SMD) = -0.61; 95% CI = -1.04 to -0.19) and 15 min (SMD = -0.72; 95% CI = -1.14 to -0.19), had a higher success rate (RR = 3.55; 95% CI: 1.89 to 6.64) and a less frequent need for rescue medicine (RR = 0.51; 95% CI = 0.36 to 0.72) than the control group. These beneficial effects were not observed when an antiemetic was administered. Furthermore, intranasal lidocaine use had no significant influence on the relapse rate (RR = 0.89; 95% CI = 0.51–1.56), regardless of the use of antiemetics. Using lidocaine caused local irritation in up to 49.4% of the patients in one report but did not cause major adverse events. Conclusion Intranasal lidocaine can be considered a useful option for patients with an acute migraine. It yields a high success rate, a low pain intensity, an infrequent need for rescue medicine, and tolerable adverse events. The administration of antiemetics is an important confounding factor.
