Natural killer (NK) cells play critical roles in immune surveillance and homeostasis maintenance through cytotoxicity and cytokine release. The ability of NK cells to eliminate target cells without the need for prior antigen recognition or antibody involvement has drawn considerable attention for translational and clinical applications. As clinical applications continue to broaden, interest in NK cell assays has been growing markedly. This review provides an in-depth discussion of current clinical applications of NK cell assays, including NK cell phenotype, frequency, and functional activity assessments. This review further highlights the diagnostic potential of these assays in terms of hemophagocytic lymphohistiocytosis and potential NK cell biomarker candidates in diverse pathological contexts, such as cancer, infection, autoimmune diseases, and other diseases. By integrating clinical insights with technological advancements, NK cell assays can serve as valuable tools for disease diagnosis, prognosis, and therapeutic monitoring.

Objective: This study evaluated the health behavior level of urological cancer survivors after surgery.Understand the experience of change and identify the factors that affect it for health. Selection of the best intervention steps and effective intervention adopt a lifestyle. It is intended to contribute to the creation of basic data for development of guidelines. Methods: The study was conducted with patients diagnosed with urological cancer at a hospital in Seoul.Study data were obtained by having 100 patients who agreed to the study self-fill out a questionnaire through interviews, and the 2018 World Cancer Research Fund and American Institute for Cancer Research Score (2018 WCRF/AICR SCORE) was used to estimate the level of health behavior. Results: The study examines health behavior among urolgical cancer survivors based on the 2018 WCRF/AICR SCORE. Higher household income and younger age were associated with better health behavior scores, with those under 60 and earning over 3 million won being more likely to have higher scores. Conclusion Based on these results, this study requires comprehensive data collection considering the missing variables, suggesting that high household income and young age can positively affect healthy behavior. In addition, we conclude that education for cancer survivors and development of strategies to bridge the health gap for low-income and elderly populations are necessary.

Background: Inflammasomes are key in the initiation of inflammatory responses and serve to de-fend the organism. However, when the immune system is imbalanced, these complexes contribute to tumor progression. The purpose of this study was to investigate the effect of non-canonical inflammasomes on glioma malignancy. Methods: We performed bioinformatics analysis to confirm the expression of canonical andnon-canonical inflammasome-related molecules according to the degree of malignancy through immunohistochemical examination of glioma tissues obtained with patient consent from our institution. Results: Bioinformatics analysis confirmed that the expression levels of non-canonical inflam-masome-related molecules were significantly higher in tumor tissues than in normal tissues, and they also increased according to malignancy, which adversely affected the survival rate. Furthermore, in gliomas, positive correlations were found between N-form gasdermin-D, a key molecule associated with the non-canonical inflammasome, and other related molecules, including NLRP3, caspase-1, caspase-4, and caspase-5. These results were verified by immunohistochemical examination of glioma tissues, and the expression levels of these molecules also increased significantly with increasing grade.In addition, the features of pyroptosis were confirmed. Conclusion This study identified the potential of non-canonical inflammasomes as aggressiveness markers for gliomas and presented a perspective for improving glioma treatment.

Red ginseng (RG) exerts anti-inflammatory, anti-proliferative, and immunomodulatory effects on endometriosis through the regulation of microRNA (miRNA) expression. It may also ameliorate endometriosis by affecting the expression of multiple miRNAs simultaneously, rather than acting on a single miRNA at a given time. Since studies on the overall effects of RG on endometriosis via the regulation of miRNA expression are lacking, the current study aimed to explore the global effect of RG on miRNA expression in a mouse model of endometriosis. Methods: To establish the mouse model, the uterine horn of donor mice was implanted into the lateral side of the recipients’ peritoneum, followed by vehicle or RG treatment for 8 weeks. Results: To confirm the effects of RG on the established mouse model, the size of the implanted uterus was measured; it was found to be lower in mice from the RG group than in mice from the control group. miRNA expression profiles in the implanted uterus of the mouse model of endometriosis after vehicle or RG administration were analyzed using microarray technology. Thereafter, seven candidate miRNAs and 125 candidate genes (miRNA targets) were identified through a bioinformatics analysis. Conclusion: The present findings suggest that RG regulates the expression of multiple miRNAs and mRNAs, thereby alleviating endometriosis in a mouse model of the disease.

OBJECTIVE: To evaluate the nonsteroidal anti-inflammatory drugs (NSAID)-sparing effect of symptomatic slow-acting drugs for osteoarthritis (SYSADOA) in knee osteoarthritis (OA) patients. METHODS: A retrospective study was conducted on a cohort of knee OA patients who visited a single academic referral hospital from 2013 to 2014. Among all patients, NSAID users in their first visit were extracted and divided into SYSADOA users and SYSADOA non-users. All patients were observed from their first visit with knee OA to their last visit, NSAID discontinuation, or the date of data collection, July 2017 (mean observational periods: 369.1 days). To evaluate the NSAID-sparing effect of SYSADOA, Cox regression analysis was performed after adjusting for confounding factors. RESULTS: Patients for this study (n=212) were divided into SYSADOA users (n=57) and SYSADOA non-users (n=155). The mean age (68.8 vs. 66.6 years old, p=0.31) and the number of comorbidities (p=0.73) were comparable between the two groups. The SYSADOA users showed higher Kellgren–Lawrence (KL) grade (66.7% of patients with more than KL grade 3) than SYSADOA non-users (42.6% of patients with more than KL grade 3) (p=0.02). In treatment, the frequency of intra-articular injection was higher in the SYSADOA user group than the SYSADOA non-user group (33.3% vs. 9.0%, p<0.01). In Cox regression analysis, SYSADOA use contributed to NSAID discontinuation in knee OA patients (hazard ratio 2.97, 95% confidential interval 1.42∼6.22). CONCLUSION: This real-world analysis demonstrated that SYSADOA use combined with NSAIDs had a significant effect on NSAID discontinuation in patients with knee OA.

PURPOSE: Nipple sparing mastectomy provides good cosmetic results and low local recurrence rates for breast cancer patients. However, there is a potential risk of leaving an occult tumor within the nipple, which could lead to cancer relapse and poor prognosis for the patient. The objective of this study was to investigate the occult nipple involvement rate in mastectomy specimens, and to identify preoperative magnetic resonance imaging (MRI) findings and the clinicopathological characteristics of the primary tumor that may correlate with nipple invasion. METHODS: Four hundred sixty-six consecutive mastectomy samples with grossly unremarkable nipples were evaluated. Demographic and clinicopathological data were collected. Nipple involvement was evaluated using serial histological sections. The tumor size and tumor-nipple distance were measured using preoperative MRI images. RESULTS: Thirty-six of the 466 therapeutic mastectomy specimens (7.7%) were found to have occult nipple involvement. In univariate analysis, tumor size, tumor-nipple distance, lymph node status, p53 mutation, and lymphovascular invasion (LVI) were found to influence the likelihood of nipple involvement. Multivariate logistic regression analysis, adjusted by lymph node status, p53 mutation, and LVI, showed that tumor size and tumor-nipple distance were predictive factors indicating nipple involvement. With regard to tumor location, only tumors in the central area of the breast showed a significant association with nipple involvement. CONCLUSION: In this study, a statistically significant association was found between occult nipple involvement and tumor size, tumor-nipple distance, axillary lymph node status, LVI, and p53 mutation. A cutoff point of 2.2 cm for tumor size and 2 cm for tumor-nipple distance could be used as parameters to predict occult nipple involvement.

Induced pluripotent stem cells (iPSCs) generated from somatic cells of patients can provide immense opportunities to model human diseases, which may lead to develop novel therapeutics. Huntington's disease (HD) is a devastating neurodegenerative genetic disease, with no available therapeutic options at the moment. We recently reported the characteristics of a HD patient-derived iPSC carrying 72 CAG repeats (HD72-iPSC). In this study, we investigated the in vivo roles of HD72-iPSC in the YAC128 transgenic mice, a commonly used HD mouse model carrying 128 CAG repeats. To do this, we transplanted HD72-iPSC-derived neural precursors into the striatum of YAC128 mice bilaterally and observed a significant behavioral improvement in the grafted mice. Interestingly, the transplanted HD72-iPSC-derived neural precursors formed GABAeric neurons efficiently, but no EM48-positive protein aggregates were detected at 12 weeks after transplantation. Taken together, these results indicate no HD pathology was developed from the grafted cells, or no transmission of HD pathology from the host to the graft occurred at 12 weeks post-transplantation.
