In this study, we examined the expressions of VHL and miR-223 in ccRCC patients' tissues to investigate the possible role in the development of ccRCC.Methods and results This study collected five expression profiles (GSE36139, GSE3, GSE73731, GSE40435, and GSE26032) from Gene Omnibus Data. Expressions of VHL and miR-223 in paraffinized tumor and normal tissues of 100 Turkish patients' ccRCC tissues were determined by bioinformatic data mining and real-time quantitative polymerase chain reaction (qRT-PCR). The VHL gene was subjected to mutational analysis by DNA sequencing, and pVHL was analyzed using western blotting. Our study's t-test and Pearson correlation analysis showed that VHL gene expression in tumoral tissues with a - 0.39-fold decrease was not significantly lower than normal tissues (p = 0.441), and a 0.97-fold increase miR-223 (p = 0.045) was determined by real-time PCR. Also, as a result of DNA sequence analysis performed in the VHL gene, it was found that 26% of the patients have mutations. The mutations for (VHL):c.60C>A (p.Val20=) and (VHL):c.467delA (p.Tyr156Leu) was detected for the first time in Turkish patients.Conclusions The present study demonstrated that the differences in the expression levels of miR-223 have the potential to be biomarkers to determine the poor prognosis in ccRCC.Publication Cancer in patients with primary immune deficiency(Wiley, 2016-11-01) Demirkaya, M.; Sevinir, B.; Kılıç, S.; Öztürk, H.; Demirkaya, Metin; SEVİNİR, BETÜL BERRİN; KILIÇ GÜLTEKİN, SARA ŞEBNEM; ÖZTÜRK NAZLIOĞLU, HÜLYA; Uludağ Üniversitesi/Tıp Fakültesi/Çocuk İmmunoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Onkoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; IXQ-3375-2023; 0000-0002-3232-7652; AAH-1570-2021; EUG-4353-2022; IDK-5744-2023Publication Tuberculous lymphadenitis in children(Aves Yayıncılık, 2012-03-01) Bozdemir, Şefika Elmas; Nazlıoğlu, Hülya Öztürk; Hacımustafaoğlu, Mustafa; Çelebi, Solmaz; Bozdemir, Şefika Elmas; ÖZTÜRK NAZLIOĞLU, HÜLYA; HACIMUSTAFAOĞLU, MUSTAFA KEMAL; ÇELEBİ, SOLMAZ; Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Sağlığı ve Hastalıkları Anabilim Dalı/Çocuk Enfeksiyon Hastalıkları Bilim Dalı; Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı; 0000-0003-4646-660X; HZV-5920-2023; JIO-9152-2023; CTG-5805-2022; JHN-1091-2023Objective: Tuberculous lymphadenitis is the most common form of extrapulmonary tuberculosis in childhood. The aim of this study is to evaluate the epidemiological and clinical signs and treatment results of patients with tuberculous lymphadenitis.Material and Method: Epidemiological properties, clinical signs, treatment regimens of 19 patients with tuberculous lymphadenitis proven by histopathological and/or microbiological evaluation in Uludag University Medical Faculty, Pediatric Infectious Disease Department between years 2005-2010 were evaluated.Results: Of patients, 68.4% were girls with a mean age of 7.45 +/- 4.59 years (12 months-16 years). The patients < 5 years were 31.5%. The most frequent complaint was swelling in 94.7% of patients. Three patients (15.8%) had a member with active tuberculosis in his/her family. One patient (5.3%) had been treated for pulmonary tuberculosis 2 years earlier. One patient (5.3%) had miliary and meningeal tuberculosis at the same time due to interferon gamma receptor deficiency. The tuberculin skin test (TST) was applied to all patients and resulted in > 15 mm enduration in 78.9%, 10-14 mm enduration in 21.1%, BCG vaccine scarring was present in 94.7% of patients while 57.9% had one scarring, 57.8% had two scarrings. The most frequent localization of disease was the cervical lymph nodes in 47.4%. In 94.7% of patients, diagnosis depended on revealing granulomatous inflammation and caseification necrosis of lymph nodes by excisional biopsy. Acid-alcohol-resistant bacillus (AARB) was seen and grew Mycobacterium tuberculosis complex in lymph node specimens of two of the patients who were diagnosed by lymph node biopsy. Side effects of antituberculous drug treatment were seen in 10.6% of patients. Of all patients, 94.7% recovered while one patient who had interferon gamma receptor deficiency died.Coclusion: Because tuberculous lymphadenitis is not a rare entity in children in our country, it must be considered in the differential diagnosis of lymphadenopathies.Publication Successful treatment of central nervous system involvement in posttransplant EBV-related lymphoproliferative disease with intrathecal rituximab therapy(Lippincott Williams & Wilkins, 2023-07-01) Aslan, Fatma; Güler, Salih; Evim, Melike Sezgin; Aslıer, Mustafa; Yazıcı, Zeynep; Nazlıoğlu, Hülya Öztürk; Güneş, Adalet Meral; ASLAN, FATMA; GÜLER, SALİH; SEZGİN EVİM, MELİKE; ASLIER, MUSTAFA; YAZICI, ZEYNEP; ÖZTÜRK NAZLIOĞLU, HÜLYA; MERAL GÜNEŞ, ADALET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatrik Radyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Kulak Burun Boğaz-Baş Boyun Cerrahisi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatrik Hematoloji Anabilim Dalı.; 0000-0003-1577-8109; 0000-0002-6180-901X; GBG-1533-2022; AAA-2856-2021; IRI-7023-2023; CCA-0193-2022; AAI-2303-2021; JIO-9152-2023; JGX-6145-2023The posttransplant lymphoproliferative disease is a severe cause of morbidity and mortality following allogeneic hematopoietic stem cell transplantation. Central Nervous System involvement in EBV-related PTLD is rare, and there is no standard treatment recommendation. We present our patient and discuss other previously reported cases of EBV-associated PTLD with CNS involvement.Publication Correlation between ubiquitin e3 ligases (siahs) and heat shock protein 90 in breast cancer patients(Iranian Scientific Society Medical Entomology, 2022-08-01) Takanlou, Leila Sabour; Çeçener, Gülşah; Takanlou, Maryam Sabour; Nazlioglu, Hulya Ozturk; Unlu, Havva Tezcan; Isik, Ozgen; Egeli, Unal; Tunca, Berrin; Çubukcu, Erdem; Tolunay, Sahsine; Gokgoz, Mustafa Sehsuvar; Cecener, Gulsah; ÇEÇENER, GÜLŞAH; Nazlioglu, Hulya Ozturk; ÖZTÜRK NAZLIOĞLU, HÜLYA; Isik, Ozgen; IŞIK, ÖZGEN; Egeli, Unal; EGELİ, ÜNAL; Tunca, Berrin; TUNCA, BERRİN; Çubukcu, Erdem; ÇUBUKÇU, ERDEM; Tolunay, Sahsine; TOLUNAY, ŞAHSİNE; 0000-0002-1928-992X; 0000-0002-3820-424X; 0000-0002-1590-4833; 0000-0002-0910-4258; 0000-0002-9541-5035; 0000-0001-7904-883X; 0000-0002-1619-6680; KGL-6846-2024; AAH-1420-2021; GRE-6268-2022; AAW-9602-2020; GYU-0252-2022Background: Breast cancer is a heterogeneous disease and differences in the expression levels of the ER, PR, and HER2 the triplet of established biomarkers used for clinical decision-making have been reported among breast cancer patients. Furthermore, resistance to anti-estrogen and anti-HER2 therapies emerges in a considerable rate of breast cancer patients, and novel drug therapies are required. Several anomalous signaling pathways have been known in breast cancer have been known; heat shock protein 90 (HSP90) is one of the most plenty proteins in breast cells. The family of ubiquitin ligases such as SIAH1 and SIAH2 is known to specifically target misfolded proteins to the proteasome; also, they have been illustrated to play a role in RAS signaling and as an essential downstream signaling component required for EGFR/HER2 in breast cancer.Methods: The expression of SIAH2, HSP90, and HER2 was assessed by quantitative Real-Time PCR in 85 invasive ductal carcinoma breast tumor samples at Uludag University Hospital in Turkey during the years 2018-2019, and its association with the clinicopathologic variables of patients was evaluated.Results: HSP90, SIAH1, and SIAH2 were significantly (P=0.0271, P=0.022, and P=0.0311) upregulated tumor tissue of patients with breast cancer. Moreover, this study observed a significant association between the high expression of SIAH2/ HSP90 with ER status, high expression of HSP90 with Recurrence/ Metastasis, and high expression of SIAH2 with Ki-67 proliferation index.Conclusion: The HSP90 and SIAH2 expressions play a significant role in breast cancer development by combining the experimental and clinical data obtained from the literature.Publication Diffuse large B-cell lymphoma presenting with masses in the pineal and adrenal glands(Wiley, 2019-03-01) Bilgin, Cem; Korkmaz, Barış; Soylu, Esra; Öztürk, Hulya; Öztürk, Kerem; BİLGİN, CEM; KORKMAZ, BARIŞ; Soylu, Esra; ÖZTÜRK NAZLIOĞLU, HÜLYA; Öztürk, Kerem; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; 0000-0001-9664-2347; HHS-7433-2022; E-1228-2018; FHT-9776-2022; DSW-1175-2022; IXQ-3375-2023Key Clinical Message Magnetic resonance imaging (MRI) may offer several potential advantages in the evaluation of lymphoma with the additive value of H-1-MRS for differential diagnosis. Even though lymphoma has unique imaging findings on CT and multiparametric MRI, definite diagnosis must be thoroughly established by histopathological examination.Publication Clinicopathological features of extranodal lymphomas: 15 years' experience of a single center(Düzce Üniversitesi, 2021-01-01) Coşkun, Sinem Kantarcıoğlu; Nazlıoğlu, Hülya Öztürk; Büyükuysal, Çağatay; ÖZTÜRK NAZLIOĞLU, HÜLYA; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; FLN-9596-2022Objective: In this study, we aimed to evaluate the localization and histopathological diagnosis, and clinicopathologic characteristics of primary extranodal lymphomas.Methods: The pathology reports between 2001 and 2015 in the archives of Uludag University Faculty of Medicine Pathology Department were reviewed and all cases with an extranodal lymphoma diagnosis were analyzed. The information about the diagnosis, tumor localization, symptoms at presentation, presence of B symptoms, lymphocytosis and anemia, chronic infection and chronic disease and concomitant secondary malignancy, tumor diameter, the involvement of another extranodal organ, lymph node, bone marrow, spleen, liver, stage of the disease, serum B2 microglobulin, LDH, albumin levels, sedimentation rate were documented. The localization, histopathological types, age groups, male/female ratios in cases of primary extranodal lymphoma were evaluated.Results: Total sum of 1743 patients were diagnosed with lymphoma. 480 (%27,53) of these cases were extranodal lymphomas. The most commonly encountered locations of extranodal lymphomas were the skin and the gastrointestinal system. There were 226 primary extranodal skin, 90 gastrointestinal system, 44 central nervous system, 8 genitourinary system, 50 head and neck, 18 musculoskeletal system and soft tissue, 9 mediastinum, 3 bronchus, 10 orbital, 2 liver, 6 pancreas, 4 omentum, 8 endocrine system, and 2 breast located cases. 237 of the primary extranodal lymphomas from our work were mature T/NK celled neoplasias. There were 250 patients with mature B cell lymphoma, 5 cases of Hodgkin lymphoma, and 5 cases of precursor lymphoid neoplasia.Conclusions: The data from our series were coherent with the literature. Due to the small number of cases with some localization and some histopathological diagnosis, no significant results could be reached about these entities.
