[PMID: 38370142 PMCID: PMC10872011 DOI: 10.1093/toxres/tfae015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 12/22/2023] [Accepted: 01/18/2024] [Indexed: 02/20/2024] Open
Abstract
In present study, it was purposed to determine the in vitro effect of the extract obtained from the pomegranate (Punica granatum L.) peel on the breast cancer cell line. MDA-MB-231 cells were exposed to pomegranate peel extract (PoPx) at 37 °C and 5% CO2 for varying durations (24 and 48 h) and doses (25 and 50 μg/mL). At the end of the incubation periods, argyrophilic nucleolus organizer regions (AgNOR) protein status, cell viability/apoptosis and cell cycle of MDA-MB-231 cells were examined in the Muse Cell Analyzer device. Cell viability was observed to be decreased when the groups treated with PoPx were compared with the control group. The group in which apoptosis was observed with the highest value was 50 μg/mL PoPx group (p < 0.05). In the cell cycle test, the number of cells in the G0/G1 stage was found to be significantly higher in the 25 μg/mL PoPx group compared to the control and 50 μg/mL PoPx groups at the end of the 24-h incubation period (p < 0.05) The results also supported cell cycle and apoptosis, and at the end of 24 h, Total AgNOR area(TAA)/Total nuclear area (NA) ratio and AgNOR numbered decreased on the 50 μg/mL PoPx group and were found to be statistically significant compared to the control group (p < 0.05). Consequently, it was determined that PoPx increased apoptosis on breast cancer cells by various mechanisms and inhibited cell viability/cell growth. This study showed that the widespread consumption of PoPx may be effective in preventing cancer formation and slowing its progression.

Abstract
Objective: Nucleolar proteins have important functions in the regulation of cell homeostasis and play a crucial role in sensing various types of stress, such as genotoxic stress. Propolis has epithelial, analgesic, antibacterial, antifungal and antiviral effects. This study aimed to evaluate the gene expression levels of nucleolar proteins: nucleolin (NCL); nucleophosmin (NPM1); and upstream binding transcription factor (UBTF), as well as the benefits of propolis in wound healing. Method: This experimental study was conducted by creating clean and clean–contaminated wounds according to the Surgical Site Infection Guidelines, 2016. A total of seven animal groups were included in the study: control; laparotomy; anastomosis; fucidic acid with/without anastomosis; propolis with/without anastomosis Results: Statistically significant differences of levels of gene expression among the groups were detected for NCL (p=0.004), NPM1 (p=0.011) and UBTF (p=0.000). When the expression levels of the related genes and blood parameters are considered, the relationship between NCL, NPM1 and UBTF expression levels and blood parameters (NE, EO, NE(%), LY, LY(%), EO, EO(%), MO, MO(%), RBC, HB, HCT, MCV, MCHC, RDW, RDW(%), PLT, PDW and PCT) were statistically significant. Conclusion: The nucleolar proteins such as NCL, NPM1 and UBTF have important functions in cell viability and its maintenance under various condition such as stress and injury. Additionally, propolis has positive benefits in wound healing and in the prevention of wound infection. Our findings provide the first insights into the putative role of those proteins in wound healing.

Abstract
Aim: Lung cancer is the leading cause of mortality from cancer across the world. In this study, the use of serum nucleolin (NCL) and nucleophosmin (NPM1) levels as a marker in the diagnosis, prognosis and treatment response evaluation in lung cancer was investigated. Materials and Method: NCL and NPM1 levels of serum samples taken before chemotherapy and after 3-4 courses of chemotherapy from the control group and the patients diagnosed with lung cancer were studied using ELISA method. Results: Serum NCL and NPM1 levels of the patients were higher than of the controls (p = 0.085 for NCL, p = 0.000 for NPM1). NCL and NPM1 levels by histopathologic type were significantly higher in adenocarcinoma than in squamous cell carcinoma (p < 0.05 for each). In view of the treatment responses to chemotherapeutic agents, there was a statistically insignificant difference between the values before and after chemotherapy (p > 0.05 for each). Conclusion: High serum NCL and NPM1 levels were found to correlate with poor prognosis, poor treatment response and low survival rate. It can be concluded that serum NCL and NPM1 levels in lung cancer can be used as diagnostic and prognostic markers for the disease.

Kabaklıoğlu M, Eroz R, Kaya M. May Argyrophilic Nucleolar Organizer Regions Be Used as a Biomarker for the Detection of the Degree of Ischemic Damage Instead of Tunel in Testicular Torsion? Medicina (B Aires) 2021; 57:medicina57111177. [PMID: 34833395 PMCID: PMC8619308 DOI: 10.3390/medicina57111177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 10/19/2021] [Accepted: 10/25/2021] [Indexed: 11/23/2022] Open
Abstract
Background and Objectives: It is of great importance to obtain information about the severity of ischemic damage and duration of testicular torsion for an effective treatment strategy. Nucleolar-organizing regions (NORs) are sites of the ribosomal genes composed of ribosomal DNA and proteins. Post-silver staining NORs are termed “AgNOR”. Since AgNORs clearly reveals the self-renewal potential of cells damaged in ischemic events, we performed the current study. Materials and Methods: The study was carried out in four groups as control, sham, early, and late T/D. In the surgical groups, testes were corrected after a 4-h ischemia period. Testicular tissue samples were taken on the third day after detorsion in group 1, 2, 3, and on the tenth day after detorsion in group 4. TUNEL and silver stainings were applied to all samples. Results: The differences were significant among the groups for both mean AgNOR number and total AgNOR area/total nuclear area (TAA/TNA). Moreover, the differences between control and early torsion-detorsion (T/D), between control and late T/D, between sham and early T/D, between sham and late T/D, and between early T/D and late were statistically significant for AgNOR amount. Furthermore, statistically significant differences among the groups for an average number of apoptotic cells per tubule and the percentage of apoptotic tubule values were detected. Discussion: The apoptotic index gives the ratio of cells that are damaged and will die in a programmed way and cells that remain intact, rather than show the viability of the returning testicle. However, by measuring cells that regenerate with AgNOR, we can show not only those that survive but also cells that can repair themselves. Conclusion: AgNOR proteins are usable for the early observation of ischemic injury levels. The amount of AgNOR protein can enlighten us about the extent of testicular damage after T/D treatment. It may also help the physician in the development of effective treatment strategies for cases.

Abstract
Cancer severely threatens human health currently, promoting the rapid development of cancer treatment strategies. In addition to cancer therapy, assessment of cancer prognosis, which can evaluate the success with treatment and chances of recovery as well as assist to make subsequent therapeutic schedule, is also remarkably indispensable and important. Conventional technologies can't provide rapid and highly-sensitive assessment of cancer prognosis at cytological level. Herein, an effective nitrogen doped carbon dots with intrinsic nucleolus-targeting capability and high fluorescence quantum yield are synthesized, characterized and employed for fluorescence imaging of nucleolus, which is closely related to the biological alteration of cancer cell. The cancer prognosis thus can be accurately (limit of detection: 50 nM) and rapidly (5 min) assessed at subcellular organelle level from nucleolar characteristics, which are visualized and analyzed by the captured fluorescence images. Outstanding assessment performance endows the proposed technology with great potential for future clinical research.

Abstract
The aims of the study are to detect whether there are any possible effects of chronic carbon monoxide (CO) exposure on the argyrophilic nucleolar-organizing region (AgNOR)–associated protein synthesis and evaluate any possible relationship between the amount of AgNOR protein and the level of myocardial injury also and between AgNOR and histopathological evaluation methods. Adult male albino Wistar rats ( n = 18) were randomly divided into three groups (groups A, B, and C). Group A served as control, while groups B and C were rats exposed to CO gas chronically (1000 and 3000 ppm CO concentration with a flow rate of 4 L/min for 30 min/day for 7 days, respectively). Total AgNOR area/nuclear area (TAA/NA) and the mean AgNOR numbers for each myocyte nucleus were determined. There were significant differences among all groups for TAA/NA ratio. These differences were not significant for mean AgNOR numbers. According to the histopathological evaluation scores, there were significant differences between the groups. The differences were significant among the groups for loss of sarcomere pattern. A strong positive correlation between histopathological injury scores and TAA/NA ratio was found ( Rsq = 0.48; p = 0.002), however, the correlation was not significant for mean AgNOR numbers ( Rsq = 0.08; p = 0.25). In conclusion, TAA/NA ratio can be used as an indicator for obtaining information about the level of myocardial damage instead of histopathological evaluation scores.

Abstract
BACKGROUND Nucleolus organizer regions (NORs) consist of the rRNA coding gene family (rDNA) in the cell nucleus. The argyrophilic proteins are selectively stained with silver nitrate and bind these regions. It was reported that NOR (rDNA) activity decreases in human lymphocytes, fibroblasts and bone marrow with age. However, to our knowledge there have not been any studies related to the NORs in oral epithelial cells of healthy individuals. AIM Our aim is to detect any correlation between age and Total AgNOR area/Total nucleus area (TAA/TNA) values in buccal epithelial cells of healthy individuals. METHODS Oral epithelial cells from 50 healthy individuals (age range of 2-80 years old) were spread onto a clean glass slide, air dried and fixed. Then the AgNOR staining protocol was performed on these cells. TAA/TNA ratio and AgNOR dots were calculated using software. From each person 50 oral epithelial cells were evaluated. RESULTS Statistically significant correlations were found between mean TAA/TNA values and age (Rsq = 0.534, p < 0.001 for linear and Rsq = 0.728, p < 0.0001 for polynominal regression), and between AgNOR number and age (Rsq = 0.621, p < 0.001 for linear and Rsq = 0.693, p < 0.0001 for polynominal regression). CONCLUSION There is a significant correlation between age and AgNOR amount (ribosome biosynthesis rate) in buccal epithelial cells of healthy individuals. AgNORs in buccal epithelial cells may be used for detection of age.

Abstract
Introduction: Carbon monoxide (CO) is a colorless, tasteless, odorless, nonirritant gas and CO poisoning affects all organ systems. Aim: We aimed to detect any possible effects of CO exposure on the argyrophilic nucleolar organizing region (AgNOR)-associated protein synthesis of heart cells and whether there is any relationship between AgNOR protein amount and both carboxyhemoglobin (COHb) level and histopathological evaluation methods used for the detection of damage in heart tissue after CO exposure. Materials and Methods: The rats were divided into four groups (control, 1000, 3000, and 5000 ppm), each containing six rats. After CO intoxication, COHb levels were measured and the animals were killed on the 7th day. AgNOR staining was performed in the heart tissue. One hundred nuclei per rat were evaluated, and total AgNOR area/nuclear area and mean AgNOR number were analyzed for each nucleus. The CO exposure groups had significantly higher AgNOR values than the control group ( p < 0.0001). According to cardiomyopathy (CMY) scoring methods, the differences between groups 3 and 4 and groups 1 and 2 were significant ( p < 0.05). A significant positive correlation between AgNOR values and both CMY and COHb levels were detected. Conclusion: The detection of AgNOR protein amount may give information about the CMY levels and be used to detect the CO intoxication levels instead of COHb in later periods.

Abstract
Fine needle aspiration biopsy (FNAB) of the thyroid gland is an important tool for preoperative diagnosis; however, its benefit is limited for follicular lesions. Nucleolar organizer regions (NORs) are ribosomal gene regions that stain with silver (Ag) when they are active. These regions can be used to differentiate neoplastic and non-neoplastic lesions. We used a new AgNOR technique to investigate FNAB of cases diagnosed as follicular adenoma and carcinoma. Fourteen cases of follicular thyroid carcinoma (FTC) and 28 cases of thyroid follicular adenomas (FA) were stained using the silver NOR-associated protein (AgNOR) technique. One hundred nuclei per sample were examined, AgNORs were counted, and the total AgNOR area/nuclear area (TNORa/Na) ratio of each cell was calculated. We found that cases with FTC had significantly higher TNORa/Na than cases of FA. Also, cases with FTC had significantly higher AgNOR counts than cases with FA. AgNOR counting may help discriminate FTC and FA by routine cytopathology before surgery.

Abstract
In carbon monoxide (CO) poisoning, CO affects the oxygen-carrying capacity of the hemoglobin molecule. Nucleolar-organizing regions (NORs) are genetic loci on chromosomes that are composed of ribosomal DNA and proteins. NORs can be stained with silver. A total of 18 rats were exposed to CO in three different concentrations (1000, 3000, and 5000 ppm) with 6 rats as controls. The animals were euthanized 7 days after CO intoxication. Lung tissues were taken, embedded in paraffin blocks, and sectioned at 5 μm thickness. Argyrophilic nucleolar-organizing region (AgNOR) staining was carried out. One hundred nuclei per individual were evaluated, and total AgNOR number per total nuclear number and total AgNOR area per nuclear area (TAA/NA) for each nucleus were analyzed. The CO exposure groups had significantly higher TAA/NA values and AgNOR numbers than the control group ( p < 0.05). Although the differences between 1000 ppm and the other two CO-exposed groups were meaningful ( p < 0.05) in the TAA/NA values, there were no differences among the CO exposure groups for the AgNOR number ( p > 0.05). The increase in TAA/NA value depends on the increase in the CO exposure. Significant correlations between both the AgNOR values and histopathological scoring methods were found. Therefore, AgNOR staining method may be used as an indirect indicator for evaluating the degree of cell damage rate.
