    Histomorphometric Analysis of the Effects of Grape Seed Extract (vitis Vinifera) and Low-Level Laser Therapy (lllt) on Fracture Healing
    (2020) Kara, Muhammed İsa; İnan, Sevinç; Aydemir, Işıl; Taysı, Seyithan; Aras, Mutan Hamdi; Altundağ Kahraman, Sevil; Ege, Bilal; Kahraman, Sevil Altundag; Kara, İsa; Akgül, Hasan
    Aim: In this study, we aim to investigate the effects of supplementary Grape Seed Extract (GSE) and Low-Level Laser Therapy (LLLT)on fracture healing, oxidant and anti-oxidant system in experimental mandible fractures.Materials and Methods: 48 Wistar Albino rats (adult male, n=48) were used in our study. For all the subjects, a vertical fracture linethrough molar teeth in right mandibles was created and internally fixed using a four-hole microplate and four micro screws. Firstly,these subjects were randomly divided into 4 main groups (Control, GSE, LLLT, GSE+LLLLT) of 12 animals each, and then these wereindividually separated into two sub-groups of 7th and 21st days. The number of groups (n=6) was 8 in total. GSE of 300 mg/kg/day were provided to the subjects before they were sacrificed. LLLT of 23 J/cm2 was administered to two different points alongwith the fracture line at intervals of 48 hours for 7 days in the 7th day sub-groups and for 14 days in the 21st day sub-groups. Afterthe procedure, while biochemical values such as TAS, TOS and OSI are measured; histopathologically it was examined in termsof capillary number and width, inflammatory cell, fibroblast count, collagen fibers, osteoblast count, ossification and mature boneformations.Results: For biochemical analyses, there was statistically significant difference only in TAS values on either the 7th or 21st day forthe groups. Histological analyses showed that mandibular fracture healing were significantly better in the GSE and GSE+LLLT groupscompared to the control group. The group of only LLLT had limited recovery while the combination of GSE+LLLT was the best forossification.Conclusions: It is concluded that GSE may be one of the potential methods to accelerate fracture healings in mandibular fracturescommon in oral and maxillofacial surgery clinic and thus help patients recover in shorter time, and however LLLT can have positiveeffects on the process of ossification and recovery only when combined with the extract, which may result in better outcomes inclinical use.

    Adjuvant Effects of Chemotherapeutics and Metformin on Mfe-319 Endometrial Carcinoma Cell Line
    (Editura Acad Romane, 2021-04-01) Aydemir, Isil; Uluer, Elgin Turkoz; Korkmaz, Oya; Tuglu, Mehmet Ibrahim; Inan, Sevinc
    We aimed to investigate the cytotoxicity of Metformin, Cisplatin, and Paclitaxel on MFE-319 endometrial carcinoma cell line using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and immunocytochemistry assays. Half maximal inhibitory concentration (IC50) doses of three drugs alone and in the dual combinations were applied to the cells. Immunocytochemical method was performed for the cell survival and for phosphatidylinositol 3-kinase (PI3K), phosphorylated extracellular regulated kinases (pErk)-1/2, Akt-1, phosphorylated Akt (pAkt)-1/2/3 cell growth markers and angiogenic vascular endothelial growth factor (VEGF). Immunoreactivities were evaluated using H-score and analyzed using the one-way analysis of variance (ANOVA) test for statistics. It was found that these drugs caused a decrease in the immunoreactivities of these markers. Particularly, dual combination of Paclitaxel and Cisplatin decreased the immunoreactivities of PI3K, pErk-1/2, Akt-1, and pAkt-1/2/3. Cisplatin and Paclitaxel were more effective than Metformin; on the other hand, Metformin has been shown to enhance the efficacy of these two drugs. In vitro or in vivo further studies are needed to investigate the efficacy of these three drugs via PI3K/Akt signal pathway.

    Do Wortmannin and Thalidomide Induce Apoptosis by Autophagy Inhibition in 4t1 Breast Cancer Cells in Vitro and in Vivo?
    (E-Century Publishing Corp, 2021) Uluer, Elgin Turkoz; Sonmez, Pinar Kilicaslan; Akogullari, Damla; Onal, Melike; Tanriover, Gamze; Inan, Sevinc
    The aim of this study was to show the effects of autophagy inhibitor Wortmannin and antiangiogenicproapoptotic Thalidomide on autophagy and apoptosis markers in 4T1 breast cancer cells in vitro and in vivo. The half-maximal inhibitory concentration (IC50) values of 4T1 cells for Wortmannin and Thalidomide were evaluated by Methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay. After cancer formation in 28 BALB/C female mice, drugs were administered for seven days. Cells and tissue sections were evaluated for anti-phosphoinositide 3-kinase (PI3K), anti- the microtubule-associated protein 1 light chain3 (MAPLC313), anti-caspase 8, anti-caspase 9, and anti-caspase 3 immunoreactivities by immunohistochemical staining and apoptosis by Terminal Transferase dUTP Nick End Labeling (TUNEL) assay. Both PI3K and MAPLC313 immunoreactivities decreased in all treatments when compared to control group except Thalidomide treatment in primary cancer tissue. The caspase 3, 8, and 9 immunoreactivities were increased in all treatment groups and TUNEL positive cells were the highest in the Wortmannin and Thalidomide group. Our findings suggest that autophagy is an important mechanism for 4T1 cells and both Wortmannin and Thalidomide treatments inhibit autophagy and induce apoptosis. In primary cancer tissues, autophagy was not effective as in vitro. The treatment of Wortmannin and Thalidomide increased the apoptotic cells in vivo independent from autophagy inhibition. Different results may be because of microenvironment. Further studies must be done to elucidate the effect of microenvironment.

    Biocompatibility of Vertically Aligned Multi-Walled Carbon Nanotube Scaffolds for Human Breast Cancer Cell Line Mda-Mb
    (Springer Heidelberg, 2017-11-16) Akinoglu, E. M.; Ozbilgin, K.; Sonmez, P. Kilicaslan; Ozkut, M. M.; Giersig, M.; İnan, Sevinç; Gumustepe, E.
    The aim of the current study was to determine whether the MWCNT-based scaffold has a suitable structure for cell growth and provides a biocompatible environment for human MDA-MB-231 cell lines. MWCNT-based nanostructured scaffolds were produced by plasma-enhanced chemical vapor deposition (PECVD) technique. MDA-MB-231 cells were seeded on MWCNTs-textured silicon scaffolds and on pristine silicon surfaces. After 1 week of culturing, the scaffolds were prepared for SEM analysis and immunocytochemical staining was performed for the two groups (MWCNT scaffold and pristine silicon surface), using MMP-2, MMP-9, PI3K, AKT and NF-kappa B primary antibodies. SEM analyses showed that the MDA-MB-231 cells better adhered to the MWCNT-based nanostructured scaffold than the pristine silicon surface. Immunohistochemical activity of the MDA-MB-231 cells on both materials has similar staining with anti-AKT MMP-2, MMP-9 and NF-kappa B primary antibodies. Therefore, the results of the present study suggest that the MWCNT-based scaffolds enhanced cell adhesion to the scaffold and exhibited more biomimetic properties and physiological adaptation with the potential to be used for in vitro metastasis studies of BrCa cell lines.

    Structured Abstract Objective The aim of this study was to investigate the effects of omega-3 fatty acids on orthodontic tooth movement. Setting and Sample Population For this study, 56 12-week-old adult male Wistar albino rats from the Animal Laboratory at Adnan Menderes University, Faculty of Medicine, were used. Material and Methods Rats were randomly divided into seven groups (n = 8 each): control group (without any treatment), tooth movement groups (three groups of animals with only tooth movement) and omega groups (three groups of animals with tooth movement and omega-3 administration). Omega-3 fatty acids were administered to the rats systemically during the tooth movement period. On the 3rd, 7th and 14th days after the orthodontic tooth movement, the rats were sacrificed and biochemical, histological, immunohistochemical andgene expression examinations were performed. Results On the 14th experimental day, the amount of tooth movement in the omega groups was significantly lower than the tooth movement groups (P = 0.012). Biochemical experimentsshowed that the omega groups had significantly lower total oxidant levels and higher total antioxidant levels compared to the tooth movement group on the 14th experimental day (P = 0.001). The levels of RANKL, IL-6 and IL-1 beta in the omega groups were significantly lower than the tooth movement groups on all experimental days (P < 0.05). Conclusion Systemic administration of omega-3 fatty acids showed antioxidant and antiinflammatory effects and decelerate the orthodontic tooth movement.

    Continuous and Intermittent Parathyroid Hormone Administration Promotes Osteogenic Differentiation and Activity of Programmable Cells of Monocytic Origin
    (Taylor & Francis Ltd, 2022-04-27) Kir, M. C.; Onal, M. O.; Uluer, E. T.; Ulman, C.; İnan, Sevinç
    Bone healing deficiencies are challenging for orthopedic practice. The use of stem cells with scaffolds to treat bone tissue losses currently is popular for promoting regeneration of tissue. Programmable cells of monocytic origin (PCMO) may differentiate into three germ layers and may be a promising alternative treatment due to their stem cell-like properties. Parathyroid hormone (PTH) participates in bone metabolism. Intermittent administration of PTH promotes osteogenic activity of mesenchymal stem cdells (MSC). We investigated the osteogenic effects of continuous and intermittent administration of PTH on PCMO. Mononuclear cells were harvested from the peripheral blood of healthy donors. Isolated cells were cultured for six days in a de-differentiation medium. Indirect immunocytochemistry using anti-CD14, anti-CD45 and anti-CD90 primary antibodies, as well as electron microscopy were used to detect PCMO. PCMO then were cultured in an osteogenic differentiation medium supplemented with continuous or intermittent 50 ng/ml PTH. The PTH-free control group (CG), intermittent PTH treated group (IPG) and continuous PTH treated group (CPG) were cultured and assessed for their differentiation into osteogenic lineage cells by indirect immunocytochemistry using anti-collagen I, anti-osteonectin and anti-osteocalcin primary antibodies. Osteoblast-like cells obtained by continuous or intermittent PTH administration exhibited increased levels of collagen I, osteonectin and osteocalcin immunoreactivity. We found that continuous and intermittent PTH administration to PCMO enhanced their differentiation to osteogenic lineage cells and increased osteoblastic activity.

    Investigation of the Effects of Rapamycin on the Mtor Pathway and Apoptosis in Metastatic and Non-Metastatic Human Breast Cancer Cell Lines
    (Comenius Univ, 2020) Ekizceli, G.; Uluer, E. T.; İnan, Sevinç
    AIM: The aim of this study was to analyze the effects of rapamycin treatment on apoptosis via mTOR pathway in metastatic and non-metastatic human breast cancer cell lines by immunohistochemical and TUNEL analysis. METHOD: MCF-7 and MDA-MB 231 cell lines were incubated under standard conditions forming Rapamycin and control groups. In immunohistochemical evaluation; mTOR pathway was evaluated with anti-IGF1, anti-PI3K, anti-pAKT1/2/3, anti-mTORC1, anti-mTORC2 and anti-ERK1 antibodies. The effect of apoptosis was also confirmed by TUNEL method. RESULTS: In this study, activation of PI3K/AKT/mTOR and related molecular pathways in the MDA-MB 231 and MCF-7 breast cancer cell line was evaluated and it was observed that these pathways could play a key role in cancer development. Increased apoptotic cells were observed in mTORC1 inhibition by Rapamycin administration. CONCLUSION: Targeting the mTOR pathway in breast cancer treatment may be a treatment option. In addition, the demonstration and confirmation of increased apoptosis in Rapamycin treated groups suggested that Rapamycin, an inhibitor of mTOR, is promising in the treatment of breast cancer (Tab. 2, Fig. 3, Ref. 66).

    Evaluation of Jak/Stat Signaling Pathway-Associated Protein Expression at Implantation Period: an Immunohistochemical Study in Rats
    (2023-10-20) Gürel, Çevik; Kuşçu, Gökçe Ceren; Vatansever, H. Seda; Köse, Can; İnan, Sevinç; Özbilgin, Kemal; Kırmaz, Cengiz; Vatansever, Seda
    Objective: The implantation period of gestation is a complex process in which numerous molecular pathways play a role. The Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway is one of the evolutionarily conserved cascades used to transduce a multitude signals for several biological events such as implantation and uterine receptivity. Previous studies have indicated that the implantation process is disrupted by the lack of proteins involved in this pathway. However, our literature knowledge showed that there is no study evaluated the expression of JAK/STAT signaling pathwayassociated proteins during the implantation period. This study investigated the expression patterns of JAK/STAT signaling pathway-associated proteins in rats by immunohistochemical (IHC) staining according to gestational days. Methods: In this study, thirty Wistar Albino rats weighing 250-300 g, without any problems in their menstrual cycles, were used. The pregnant animals were sacrificed on the 4th, 5th, and 6th days and histochemical and IHC analysis were performed on the uterine tissues taken from these animals. Results: In this study, protein expression of JAK1, JAK2, JAK3, STAT2, STAT3, STAT4, STAT5, and STAT6 belonging to the JAK/STAT pathway was evaluated in the uterine surface epithelium, gland structures, antimesometrial region, cells of the immune system, myometrium, mesometrial region and decidual cells, which are associated with the implantation process. The result of this evaluation reveals that the expression levels of these proteins in the JAK/STAT pathway vary in different days of the implantation period in implantation-related structures. Conclusion: This study indicates that JAK/STAT signaling pathway-associated proteins can function actively in the regulation of the immunological response of the uterus and embryo-uterus interaction during the implantation period in rats. However, the findings obtained from advanced research on JAK/STAT pathway can be used for treating recurrent pregnancy failures and in enhancing assisted reproductive technology.
