Summary
Background
Forkhead box (FOX) A1 is a potential therapeutic biomarker that has been investigated in various human cancers. Limited data exist about FOXA1 biologic role in epithelial ovarian cancer (EOC).
Aim
This study assessed FOXA1 immunohistochemical (IHC) expression and evaluated its association with clinico-pathological parameters in EOC including overall and disease-free survivals (OS, DFS) and patient’s outcome.
Methods
Patient’s socio-epidemiologic, clinical, radiological, laboratory, surgical, and follow-up data were collected. After histopathologic typing, grading and staging, FOXA1 IHC expression was scored in 98 EOC specimens. Clinico-pathological associations were investigated in high-and low-FOXA1 expression groups using appropriate statistical methods. Kaplan-Meier method was used for survival analysis.
Results
FOXA1 tumor cell nuclear staining was detected in 63.3% of EOC with weak, moderate and strong scores (28.6%, 12.2% and 22.5% respectively). Comparing high- and low-expression groups (34.7% and 65.3% respectively), high FOXA1 was associated with larger tumors, low mean serum CA-125, tumor histopathology (mucinous and low-grade serous), type I EOC, limited tumor’s anatomical extent, absence of nodal or distant metastases and omental nodules, earlier FIGO stages, non-recurrent tumors and survival advantage with longer and OS and DFS (all p ≤ 0.05). Independent predictors of high FOXA1 expression included: omental nodules, tumor’s anatomical extent and tumor’s size (p ≤ 0.001, = 0.046 and = 0.023 respectively).
Conclusion
FOXA1 is frequently expressed in EOC notably mucinous and low-grade serous carcinomas in association with favorable prognostic clinico-pathological parameters and longer OS and DFS. It likely has a suppressor function in EOC and could be recommended as a prognostic and therapeutic biomarker.
It is with great pleasure that I write this editorial to welcome you to the IJCBR. This journal provides a platform for publication of original and reviews research articles, short communications, letter to editor, thesis abstract, conference report, and case studies. These types of publication are directed at the interface of the fields of cancer and biomedical research.The IJCBR relies on a distinguished expert of the Advisory and Editorial Board Members from the top international league covering in depth the related topics. They timely review all manuscripts and maintain highest standards of quality and scientific methodology and ethical concepts. Meanwhile, we take all possible means to keep the time of the publication process as short as possible.I take this chance to welcome your contributions to the IJCBR and have every expectation that it will soon become one of the most respected journals in both the fields of cancer and biomedical research.
Diabetic nephropathy (DN) is one of most prevalent diabetic complication. It remains unclear whether the anti-inflammatory Hydroxytyrosol (HT) has beneficial effects on biogenesis of diabetic renal changes. Therefore, we aimed to find out the relationship between inflammation, apoptosis, oxidative stress and the progression of DN. Also, try to assess the possible effects of HT on diabetic renal tissue. Materials and Methods: Rats were divided into: non-diabetic rats (group I) and rats with induced type II diabetes that were subdivided into: group II non-treated DM, group III treated with HT, group IV treated with glyclazide and group V treated with combined treatment. Treatments were supplied for eight weeks. Results: Administration of HT alone or with GLY significantly lowered blood glucose levels and ameliorated kidney hypertrophy index together with improving renal dysfunction parameters including creatinine in serum and urine, blood urea nitrogen, serum and urinary albumin, together with the tissue oxidative markers and inflammatory cytokines activities compared to diabetic group. These effects of HT were also reflected on histologic evaluation and Nrf2-Keap1 system expression. Conclusion:This study discovers the renoprotective effect of HT in diabetic rats. Hence, this study recommended an addition of antioxidants like HT to the management of diabetes.

Worldwide, the estimated annual incidence of ALL is 1-4.75 cases per 100,000 population with approximately 80-85% being of B-cell type. Although ALL is primarily a childhood disease and 75% of cases occur in the first 6 years of life, a second peak occurs in adults at the age of 50 years where B-cell lineage constitute 75% of cases in
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
