Retrospective Analysis of Follicular Lymphoma Patients in Trakya University School of Medicine: a Single Center Experience

DergiPark: 889334tmsjAims: To establish a dataset including demographic features, disease characteristics, and survival rate of follicular lymphoma patients in Trakya Universi- ty School of Medicine and contribute to the database of follicular lymphoma in Turkey. Methods: In this retrospective cross-sectional study, we analyzed data constituting of follicular lymphoma patients over 18 years of age followed during the years of 2015-2020 in Trakya University Division of Hematology. Results: Out of 43 patients, 22 (51.2%) were female and 21 (48.8%) were male. The mean age was 56.56 (standard deviation 13.24) years. There were 5 (11.6%) pa- tients with B symptoms, presence of bone marrow involvement was seen in 17 (39.5%) patients, lastly, there were 18 (41.9%) patients with splenomegaly. Twen- ty-one (48.8%) patients received rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and prednisone, making it the most common treatment protocol administered in our study. Conclusion: Follicular lymphoma patients usually end up getting diagnosed at an advanced stage of the disease, presenting with incidentally noticed painless lymphadenopathy. Additionally, based on evidence in the literature, a clear gap in the successful diagnosis of follic- ular lymphoma patients can be observed between developed and developing countries. To overcome this hurdle, enhanced cooperation with hematopathology may lead to an increased awareness enabling physicians to make a more accurate diagnosis. Nonetheless, further studies are still needed to fully apprehend the epidemiology of follicular lymphoma patients in Turkey

Identification of gene expression profiles in Leishmania major infection by integrated bioinformatics analyses

WOS: 000540814000017PubMed: 32360239Gene expression profiling in mouse models of leishmaniasis has given useful information to understand the molecular pathways active in lesions and to discover new diagnostic/therapeutic targets. Although the host response plays a critical role in protection from leishmaniasis and promoting disease severity, there are still unexplained aspects in the mechanism of non-healing cutaneous lesions, which need biomarkers for both targeted- therapy and diagnosis. To address this, transcriptional profiling of the skin lesions obtained from BALB/c mice infected with Leishmania major and healthy skin from naive mice were evaluated by bioinformatics analysis, and then the results were validated by Revers Transcriptase-PCR. Five genes among the up-regulated differentially expressed genes named FCGR4, CCL4, CXCL9, Arg1 and IL-1 beta were found to have relatively high diagnostic value for CL due to L. major. Pathway analysis revealed that Triggering Receptor Expressed on Myeloid Cells 1 (TREM1) signaling pathways are active in cutaneous lesions, providing new insights for the understanding and treatment of leishmaniasis.Ege University Scientific Research Projects Foundation [TGA-2019-20180]We thank Ege University Scientific Research Projects Foundation (TGA-2019-20180) for Grant Support and Dr. Yusuf Ozbel for providing L. major cell line

Promoter and histone methylation and p16(INK4A) gene expression in colon cancer

The inactivation of the cyclin-dependent kinase inhibitor p16(INK4A) gene by hypermethylation is observed in numerous types of cancer. New findings indicate that DNA and histone methylation act in concert in gene silencing. In this study, we investigated the methylation status of the p16(INK4A) gene promoter and the histone 3 lysine 9 residue in the tumors and matched normal tissue samples from patients with colorectal cancer and analyzed their association with gene expression. The methylation and expression of the p16(INK4A) gene were analyzed by real-time PCR, and histone methylation was analyzed by chromatin immunoprecipitation followed by real-time PCR. p16(INK4A) expression was significantly higher in the tumors compared to normal tissue. Mono-, di- and trimethylation levels of the H3K9 residue were similar in the tumor and normal tissue samples. We did not observe any significant correlation between p16(INK4A) methylation or expression and clinical parameters. Our results suggest that epigenetic modifications of the p16(INK4A) gene and histone lysine methylation do not play a major role in colon carcinogenesis

Effect of gemcitabine and retinoic acid loaded PAMAM dendrimer-coated magnetic nanoparticles on pancreatic cancer and stellate cell lines

WOS: 000342668300009PubMed ID: 25108345Gemcitabine is an anticancer drug used in the treatment of different cancer types, including pancreatic ductal adenocarcinoma. The maximum tolerated dose in humans is restricted by its side effects on healty cells. Furthermore, the fibrotic stroma produced by the pancreatic stellate cells prevents effective delivery of chemotherapeutic agents providing a safe-haven for the cancer cells. This becomes more of a problem considering the short half-life of this drug. Magnetic nanoparticle-based targeted drug delivery systems are a promising alternative to overcome the limitations of classical chemotherapies. The aim of this study is to obtain an effective targeted delivery system for gemcitabine using magnetic nanoparticles (MNPs) and all-trans retinoic acid (ATRA). This dual approach targets the tumor cells and its infrastructure - stellate cells - simultaneously. Gemcitabine and ATRA were loaded onto the PAMAM dendrimer-coated magnetic nanoparticles (DcMNPs), which were synthesized and characterized previously. Drug loading and release characteristics, and stability of the nanoparticles were investigated. Gemcitabine and ATRA loaded MNPs are efficiently taken up by pancreatic cancer and stellate cells successfully targeting and eliminating both cells. Results of this study can provide new insights on pancreatic cancer therapy where tumor is seen as a system with its stroma insead of epithelial cells alone. (C) 2014 Elsevier Masson SAS.
