The purpose of this systematic review is to summarize all existing evidence, regarding the immunohistochemical expression of REV-7 in different human cancer pathology specimens. Moreover, the association of REV-7 expression with disease severity (clinical course), patients' survival, prognosis, and response to various treatments, such as chemotherapy and irradiation, was investigated. Three databases (PubMed, Scopus, and Cochrane) were systematically screened, from inception to September 2, 2023, as suggested by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Only studies using immunohistochemical staining for REV-7 in paraffin-embedded cancer tissues were included. Nine studies met the inclusion criteria and were included in the final qualitative synthesis. All nine studies were retrospective and non-comparative ones. Selected studies reported immunohistochemical expression of REV-7 in different types of cancer, including testicular cancer, ovarian cancer, esophagus squamous cell carcinoma, prostate cancer, colorectal cancer, diffuse large B-cell lymphoma, breast cancer, lung cancer, and skin cancer. High REV-7 expression was associated with faster disease progression, resistance to available treatment options, and worse prognosis in the majority of included studies. These results indicate that immunohistochemical staining of REV-7 protein could potentially be used as a predictive tissue marker in certain cases. Promising results, arising from REV-7 inactivation experiments, render REV-7 targeting a potential therapeutic strategy for future cancer management, especially in the cases of chemoresistant or radioresistant disease.

Flow cytometry immunophenotypic analysis is an important and indispensable tool in the diagnosis of mature B-cell lymphomas/leukemias, particularly for small fine needle aspiration and needle core biopsy specimens which are becoming increasingly popular for diagnostic purposes. Flow cytometry immunophenotyping (FCI) has several advantages. Given its multiparametric nature, FCI can analyze the expression of multiple antigens simultaneously on the same cell of interest, qualitatively and quantitively.

Immunohistochemical (IHC) tissue profiling is a standard practice in the management of metastatic breast cancer (mBC), that enables the identification of distinct biological phenotypes based on hormone receptors' expression. Luminal-like tumors primarily benefit from a first line treatment strategy combining endocrine therapy and cyclin-dependent kinase 4/6 inhibitors. However, IHC analyses necessitate invasive procedures and may encounter technical and interpretational challenges.

Objective: To investigate the effectiveness of gelatin/polycaprolactone (GT/PCL) membranes for restoring endometrial structure and function and fertility in a rat model of endometrial injury.
Methods: We randomized 125 female Sprague-Dawley (SD) rats to the sham, natural repair (NR), estrogen (E), GT/PCL, and E-GT/PCL groups. Except for the sham group, all rats underwent uterine curettage.

Liver hepatocellular carcinoma (LIHC) is a malignancy characterized by a high rate of recurrence, metastasis, and poor prognosis. Cytochrome b561 (CYB561) has been previously reported to be associated with tumor progression, but it has not been revealed in LIHC. The aim of this study was to investigate the prognostic value and potential function of CYB561 in LICH.

Our study intended to explore Hesp antioxidant and anti-inflammatory effects against TAA hepatic fibrosis in rats. Hesperidin (Hesp), is a pharmacologically active flavonoid, found abundantly in citrus species. Our present research attempts to inspect the potential hepatoprotective role of Hesp against thioacetamide (TAA)-induced hepatic fibrosis.
