Öğe Anticancer mechanism of Sinapic acid in PC-3 and LNCaP human prostate cancer cell lines(Elsevier, 2018) Eroglu, Canan; Avci, Ebru; Vural, Hasibe; Kurar, ErcanSinapic acid (SA) is a derivative of hydroxycinnamic acid and found in various vegetables and fruit species. Aim was to evaluate the anticancer effects of SA in PC-3 and LNCaP human prostate cancer cells. The effect of SA on cell viability was determined using XTT assay. Expressions of 8 genes for apoptosis and 6 genes for metastasis were evaluated by qPCR. Caspase-3 activity was determined using caspase-3 colorimetric assay kit. Effect of SA on cell invasion was evaluated with cell invasion assay. The IC50 dose of SA in PC-3 and LNCaP cells was found to be 1000 mu M for 72 h. SA treatment increased the expression of BAX, CASP3, CASP8, CYCS, FAS, TIMP-1 and CDH1 however significantly decreased the expression of MMP-9 in PC-3 cells. In LNCaP cells, the expressions of BAX, CASP3, CASP7 and CYCS were significantly elevated; however, a decrease was seen in the expressions of CDH2, MMP-2 and MMP-9 in the SA treatment. Moreover, SA significantly increased caspase-3 activity and suppressed the cell invasion. In conclusion, it is thought that SA has anticancer effect on prostate cancer cells. However, more detailed studies should be conduct to illuminate molecular mechanism of apoptotic and anti metastatic activity of SA.Öğe The effects of Juglone-Selenium combination on invasion and metastasis in pancreatic cancer cell lines(Makerere Univ, Coll Health Sciences,Sch Med, 2022) Arikoglu, Hilal; Dursunoglu, Duygu; Kaya, Dudu Erkoc; Avci, EbruBackground: Pancreatic cancer does not show any symptoms in the early period and metastatic process is already passed when the diagnosis is done. Therefore, in the battle with pancreatic cancer, novel treatment strategies, particularly antiinva-sive and antimetastatic strategies, are needed. The cytotoxic and anticancer effects of juglone and sodium selenite (NaSe) have been showed in various cancer cells. Objectives: In this study, it is aimed to investigate the synergistic effects of juglone and selenium on PANC-1 and BxPC-3 pancreatic cancer cells. Methods: Antimetastatic effects of juglone-NaSe were carried out by adhesion and invasion assays and the genes and pro-tein expressions. Expression analysis of the CDH1, ITGB3 and COL4A3 genes and their proteins E-cadherin, beta 3 integrin and tumstatin which play role in metastasis and angiogenesis processes, were done by qPCR and immunohistochemical analysis, respectively. Results: Study findings have provided evidences that the juglone-selenium has a cytotoxic and dose dependent suppressive effect on invasion and metastasis in PANC-1 and BxPC-3 cells. Conclusion: The juglone-NaSe has the potential to be a promising agent especially to inhibit invasion and metastasis in pan-creatic cancer treatment. However, more in depth studies are needed to more clearly demonstrate the effects of juglone-se-lenium.Öğe Ginnalin A and SB203580 show additive effect on Hep-3B hepatocellular carcinoma cell line(Walter De Gruyter Gmbh, 2019) Vural, Hasibe; Ozden, Pinar; Avci, EbruObjective: Investigation of the anticarcinogenic effects of natural products with low toxicity is very important in the development of new therapeutic strategies against cancer. Ginnalin A (GA) is one of the most important phenolic compounds of Acer genus and its anticancer effect has been shown that in various cancer cell lines. SB203580, a p38 MAPK inhibitor, can inhibit cell proliferation independently of p38 MAPK. The objective of this study was to investigate combination effect of GA and SB203580 on Hep-3B cell line. Material and methods: Cell viability was determined by using XTT method after the treatment with GA, SB203580 and combination of both. Anticarcinogenic effects of GA and SB203580 both in single and in combination have been analyzed with Caspase-3 activity assay and expression levels of important genes involved in cell cycle and apoptosis were evaluated by qPCR. Results: GA and SB203580 have shown additive effect on Hep-3B cells in the combination inhibited 50% of cell viability. And, SB203580 increased the effect of GA on activation of Caspase-3 and expressions of genes important in apoptosis and cell cycle. Conclusion: This study indicates that GA and SB203580 can be an effective for development of new therapeutic strategies in hepatocellular carcinoma.Öğe Ginnalin A and SB203580 show additive effect on Hep-3B hepatocellular carcinoma cell line(Walter De Gruyter Gmbh, 2019) Vural, Hasibe; Ozden, Pinar; Avci, EbruObjective: Investigation of the anticarcinogenic effects of natural products with low toxicity is very important in the development of new therapeutic strategies against cancer.

However, little is known about its effects on invasion and metastasis. In this study, we aimed to determine the antimetastatic effect of juglone in the BxPC-3 and PANC-1 pancreatic cancer cell lines. Cytotoxic effect of juglone was evaluated by using MTT (3-(4,5-Dimethylthiazo1-2-yl)-2,5-Diphenyltetrazolium Bromide) test. The cells were treated with juglone atÖğe A novel missense mutation that may be associated with the polydactyly in the HOXD13 gene: Q241H(Bayrakol Medical Publisher, 2020) Vural, Hasibe; Avci, Ebru; Eroglu, Canan; Cinar, Ilknur; Yarar, Serhat; Gundeslioglu, OzlemAim: HOX gene cluster which is termed as architectural genes and affects the expression of certain genes on DNA are effective in the development of limb. Therefore, mutations are observed in HOX genes, particularly HOXD13, lead to various congenital limb malformations. In this context, it was aimed to determine the expression level of HOXD13 gene and screening of HOXD13 mutations in patients with congenital lower/upper limb malformations who applied to Clinic of Plastic Reconstructive and Aesthetic Surgery of Meram Faculty of Medicine Hospital in this study. Material and Method: The case group of the study was composed of 20 unrelated patients with congenital lower/upper limb malformations and the control group was composed of 20 healthy individuals. Mutation analysis was performed using NGS and Sanger sequencing methods. The expression level of the HOXD13 gene was determined by the qPCR. Results: According to the qPCR results, in the case group, a 3.43 fold decrease was observed in the expression of HOXD13 gene when compared with the control group. However, this result was not statistically significant. According to NGS and Sanger sequencing results, a 723G> T variation that could lead to amino acid changes (Q241H) and could be defined as a missense mutation was detected in a patient. Discussion: 723G> T variation observed in a patient with a polydactyly anomaly was found in the patient's mother. However, more detailed studies are needed to assess this variation, which are not found in the literature, as a missense mutation in HOXD13 associated with polydactyly.
