background: certain marker studies have practical importance in the biology of prostate cancer. the purpose of this study was to determine whether the quantification of certain neuroendocrine and proliferative markers obtained during transurethral resection or prostatectomy, would help in the prognostic evaluation of prostatic adenocarcinomas.   methods: the present study was performed on sampl...

In order to explore the role of forkhead box protein O1 (FoxO1) in lipid metabolism and cell proliferation, goose primary hepatocytes were isolated incubated with insulin or PI3K-Akt-mTOR pathway dual inhibitor NVP-BEZ235, then transfected FoxO1 interference plasmid. The related parameters proliferation measured. results firstly showed that increased intracellular TG lipids concentration (P < 0...

PURPOSE To evaluate the early histological effects of the intravesical instillation of platelet-rich plasma (PRP) in rabbit models of interstitial and hemorrhagic cystitis. METHODS Thirty-six rabbits were classified into 6 groups: saline (S), S+PRP, hydrochloric acid (HCl), HCl+PRP, cyclophosphamide (CyP), and CyP+PRP. At 48 hours after induction, PRP was prepared and intravesically administe...

Objective(s): This paper aims to investigate synergistic inhibition of polysaccharide from Sepia esculenta ink (SIP), a newly isolated marine polysaccharide in our laboratory, on breast cancer MDA-MB-231 cells exposed to cisplatin. Materials and Methods: Cell viability of MDA-MB-231 cells was determined by CCK 8 assay. Median-effect concentration was analyzed using Chou-Talalay method that was ...

Mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) is defined as a tumor composed of cells originating from neuroendocrine in the embryonic intestine and elements epithelial adenocarcinoma. To determine differentiation grade MiNEN, proliferation index was used, for which at least 500 were examined. MiNEN rare that most frequently found lower gastrointestinal tract. We present clinical case ...

BACKGROUND Excessive proliferation is one of the first steps in oncogenic activation and one of the most important biological features defining the aggressiveness of tumors. Quantifying the proportion of tumor cells in S-phase by means of flow cytometry has shown, in the past, to be useful for defining high-risk subgroups in breast cancer. Several antigens closely associated with proliferation ...

Precursors of the peptide hormone gastrin stimulate proliferation in the colorectal mucosa and promote the development of colorectal carcinoma. Gastrins bind two ferric ions selectively and with high affinity, and the biological activity of glycine-extended gastrin (Ggly) in vitro is dependent on the presence of ferric ions. The aim of the present study was to determine whether or not iron is r...

BACKGROUND Nephrotic syndrome (NS) is pathological condition characterized by heavy proteinuria. Our study investigates hypothesis that change in cell proliferation of proximal tubules influences primary cilia structure and function and promotes cystogenesis in congenital nephrotic syndrome of the Finnish type (CNF) and focal segmental glomerulosclerosis (FSGS). METHODS CNF kidneys were analy...

The Wnt family genes encode multifunctional signaling glycoproteins that are involved in the regulation of a wide variety of normal and pathological processes including tumorigenesis. In order to clarify the clinical significance of the intratumoral Wnt1 expression in non-small cell lung cancer (NSCLC), we performed an immunohistochemical study on the Wnt1 expression in NSCLCs in relation to th...

Rectal mucosal proliferation has been promoted as an intermediate marker for risk of colorectal neoplasia. Proliferating cell nuclear antigen (PCNA) immunohistochemistry has become a standard method to measure cell proliferation. Whole-crypt dissection may provide a technically simpler method for determining proliferation within an entire crypt. We conducted a study to assess the reliability (r...
