Abstract
Lung atypical adenomatous hyperplasia (AAH) is a forerunner of pulmonary adenocarcinoma. The drugs being utilized in the remediation of this type of hyperplasia have some adverse impacts. The present research focused on the potential anti-hyperplasia effect of myrtenol, an herbal terpenoid, on urethane-induced lung AAH in rats. Rats were injected with urethane (1.5 g/kg) thrice at 48 h intervals, and 20 weeks later, the animals were treated with 50 mg/kg myrtenol intraperitoneally once a day for 1 week. The ELISA method was used to measure inflammatory cytokines and oxidative parameters in the lung tissue and bronchoalveolar lavage fluid (BALF). The expression of NFκB and apoptotic/antiapoptotic factors (P53/Bcl-2) was evaluated by western blot and immunohistochemistry, respectively. H&E staining was performed for histopathological investigation. Histopathology confirmed the anti-hyperplasia effect of myrtenol, which was evidenced by the reduction of bronchoalveolar wall thickness and inflammation score. It also decreased hyperplasia progression by reducing Bcl-2, IL-10, p53, and Ki67. Compared with the urethane group, myrtenol normalized the activity of the oxidative stress markers malondialdehyde (MDA), total antioxidant capacity (TAC), glutathione peroxidase (GPX), and superoxide dismutase (SOD). Moreover, it showed an anti-inflammatory effect by decreasing lung and BALF IL-1β levels and NFκB expression. Myrtenol may have a promising effect on lung cancer treatment by counteracting lung hyperplasia via modulation of inflammation, oxidative stress, and apoptosis.

Sex-based differences in the lung immune microenvironment are associated with an increased risk of lung cancer in women. J Thorac Cardiovasc Surg 2024:S0022-5223(24)00617-2. [PMID: 39019152 DOI: 10.1016/j.jtcvs.2024.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 05/31/2024] [Accepted: 07/06/2024] [Indexed: 07/19/2024]
Abstract
OBJECTIVE Lung cancer remains a major cause of mortality worldwide, necessitating further understanding of carcinogenesis and its driving factors, including those influenced by sex-dependent variables. We hypothesized that sex-specific lung immune composition may contribute to a greater risk of lung cancer in women. METHODS Data from 1056 lung cancer screenings were examined for an association between sex and lung cancer risk using time-to-event analyses. Immune profiling by flow cytometry was performed on male and female lungs of 3 independent mouse models: nontumor bearing, KRAS mutated, and urethane-exposed carcinogenic. A comparable analysis was performed on human bronchoalveolar lavage samples (n = 81) from patients with lung cancer. RESULTS Of the high-risk screening cohort examined, 60 patients (5.7%) developed lung cancer during median follow-up of 43.4 months. Multivariable stepwise modeling retained female sex (hazard ratio, 1.56; P < .01) and age (P < .01) as prognostic indicators for lung cancer development. Female lung immune profiles in patients included T-cell phenotypes consistent with exhaustion (eg, higher proportions of PD-1+ Ki67-; P = .02), an expanded pool of regulatory T-cells (P = .03), reduced effector T-cell frequencies (P = .008), and enhancements in suppressive myeloid populations (P = .02) versus male patients, and this is recapitulated in mouse studies. CONCLUSIONS Female smokers display higher risk for lung cancer. In murine models and humans, female sex is associated with robust immunosuppression within the lung. Further examination of this link will be important in developing immune-based approaches to lung cancer interception and their optimal application across the sexes.

Abstract
Non-small cell lung cancer (NSCLC), the most common type of lung cancer, etiologically associates with tobacco smoking which mechanistically contributes to oxidative stress to facilitate the occurrence of mutations, oncogenic transformation and aberrantly activated signaling pathways. Our previous reports suggested an essential role of Sulfiredoxin (Srx) in promoting the development of lung cancer in humans, and was causally related to Peroxiredoxin IV (Prx4), the major downstream substrate and mediator of Srx-enhanced signaling. To further explore the role of the Srx-Prx4 axis in de novo lung tumorigenesis, we established Prx4-/- and Srx-/-/Prx4-/- mice in pure FVB/N background. Together with wild-type litter mates, these mice were exposed to carcinogenic urethane and the development of lung tumorigenesis was evaluated. We found that disruption of the Srx-Prx4 axis, either through knockout of Srx/Prx4 alone or together, led to a reduced number and size of lung tumors in mice. Immunohistological studies found that loss of Srx/Prx4 led to reduced rate of cell proliferation and less intratumoral macrophage infiltration. Mechanistically, we found that exposure to urethane increased the levels of reactive oxygen species, activated the expression of and Prx4 in normal lung epithelial cells, while knockout of Prx4 inhibited urethane-induced cell transformation. Moreover, bioinformatics analysis found that the Srx-Prx4 axis is activated in many human cancers, and their increased expression is tightly correlated with poor prognosis in NSCLC patients.

JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:1278092. [PMID: 35083020 PMCID: PMC8786510 DOI: 10.1155/2022/1278092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 10/02/2021] [Accepted: 11/20/2021] [Indexed: 11/17/2022]
Abstract
Quetiapine combined with sodium valproate is an effective and more suitable drug treatment for Alzheimer's disease. At present, there are relatively few studies on the combined action mechanism of these two drugs. This study has certain practical value. Alzheimer's disease is a multifaceted, highly genetically heterogeneous neurodegenerative disease. The main clinical manifestations are memory loss, abnormal mental behavior, and loss of various cognitive functions. In order to improve the symptoms of patients with Alzheimer's disease, especially those with mental symptoms, this article combines quetiapine and sodium valproate, two commonly used drugs for the treatment of mental illnesses, and applies them to different levels of Alzheimer's and observes the results of the combination's curative effect. This article introduces Alzheimer's disease and its potential mental behaviors in the method section, and it also introduces the mechanism of action of quetiapine and sodium valproate. For the algorithm, this paper introduces a data mining algorithm to understand the effect of drug efficacy. In the experimental part, firstly, it introduces the experimental objects, the proportion of medicines, and the statistical methods. Secondly, this article covers adverse reactions, inflammatory factors and vascular endothelial indicators, Alzheimer's disease performance, MOAS score, treatment effect evaluation, and satisfaction surveys. It can be seen from the experiment that, in mental behavior, the experimental group decreased from 8.2 before treatment to 0.5, and the control group decreased from 7.1 before treatment to 2.6. It can be seen that the scores of the experimental group changed after receiving the treatment of quetiapine combined with sodium valproate.

Abstract
Ki67 is a marker for proliferation of a given cell population. Low expression of Ki67 may be associated with a favourable outcome. We investigate how the proliferation index correlates with the location, morphology and behaviour of WHO grade II ependymomas with a single-centre cohort study of adult patients admitted for surgery of WHO grade II ependymomas between 2008 and 2018. Seventeen patients were included, seven had supratentorial and 10 had infratentorial tumours. Three patients died and eight had recurrent disease. Age, gender, location, extent of resection, chemotherapy, radiotherapy and histological markers were not associated with tumour progression. Both unadjusted and adjusted analysis confirmed a higher Ki67 index in male patients. Sensitivity analysis further supported the correlation between Ki67 and male gender. Ki67 may be sex specific but does not seem to correlate with survival and time to recurrence in this series.

Respir Res 2018; 19:150. [PMID: 30103737 PMCID: PMC6088431 DOI: 10.1186/s12931-018-0843-7] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Accepted: 07/13/2018] [Indexed: 02/08/2023] Open
Abstract
Background Lung cancer ranks as the leading cause of cancer-related deaths worldwide and we performed this meta-analysis to investigate eligible studies and determine the prognostic effect of Ki-67. Methods In total, 108 studies in 95 articles with 14,732 patients were found to be eligible, of which 96 studies reported on overall survival (OS) and 19 studies reported on disease-free survival (DFS) with relation to Ki-67 expression in lung cancer patients. Results The pooled hazard ratio (HR) indicated that a high Ki-67 level could be a valuable prognostic factor for lung cancer (HR = 1.122 for OS, P < 0.001 and HR = 1.894 for DFS, P < 0.001). Subsequently, the results revealed that a high Ki-67 level was significantly associated with clinical parameters of lung cancer including age (odd ratio, OR = 1.246 for older patients, P = 0.018), gender (OR = 1.874 for males, P < 0.001) and smoking status (OR = 3.087 for smokers, P < 0.001). Additionally, significant positive correlations were found between Ki-67 overexpression and poorer differentiation (OR = 1.993, P = 0.003), larger tumor size (OR = 1.436, P = 0.003), and higher pathologic stages (OR = 1.867 for III-IV, P < 0.001). Furthermore, high expression of Ki-67 was found to be a valuable predictive factor for lymph node metastasis positive (OR = 1.653, P < 0.001) and advanced TNM stages (OR = 1.497 for stage III-IV, P = 0.024). Finally, no publication bias was detected in any of the analyses. Conclusions This study highlights that the high expression of Ki-67 is clinically relevant in terms of the prognostic and clinicopathological characteristics for lung cancer. Nevertheless, more prospective well-designed studies are warranted to validate these findings.

Abstract
Lung cancer is the leading cause of cancer death worldwide. Cigarette smoking and exposure to chemical carcinogens are among the risk factors of lung tumorigenesis. In this study, we found that cigarette smoke condensate and urethane significantly stimulated the expression of sulfiredoxin (Srx) at the transcript and protein levels in cultured normal lung epithelial cells, and such stimulation was mediated through the activation of nuclear related factor 2 (Nrf2). To study the role of Srx in lung cancer development in vivo, mice with Srx wildtype, heterozygous or knockout genotype were subjected to the same protocol of urethane treatment to induce lung tumors. By comparing tumor multiplicity and volume between groups of mice with different genotype, we found that Srx knockout mice had a significantly lower number and smaller size of lung tumors. Mechanistically, we demonstrated that loss of Srx led to a decrease of tumor cell proliferation as well as an increase of tumor cell apoptosis. These data suggest that Srx may have an oncogenic role that contributes to the development of lung cancer in smokers or urethane-exposed human subjects.
