PURPOSE All-trans retinoic acid (RA)-incorporated nanoparticles were prepared using deoxycholic acid-conjugated dextran (DexDA). Anticancer activity of RA-incorporated DexDA nanoparticles were tested in vitro and in vivo. METHODS RA-incorporated nanoparticles were prepared by dialysis. Antiproliferative and anti-invasive potential of RA-incorporated nanoparticles were studied using CT26 color...
Trong nghiên cứu này, thành phần hóa học của cao chiết ethanol từ rễ loài W. florida “Pink Poppet” đã được đánh giá qua các phản ứng định tính. Kết quả cho thấy, trong có flavonoid, terpenoid, coumarin và saponin triterpene, nhưng không alkaloid, steroid glycoside tim. Cao xác hoạt tính kháng oxy thông khả năng loại bỏ gốc tự do DPPH với trị EC50 = 81,13 µg/mL. Nghiên sau đó gây độc trên dòng t...
Objective(s):Sea cucumber is one of the classes of echinoderms, which is considered as a health marine product and possess various biological characteristics with therapeutic application. The present investigation attempted to evaluate the potential of anti-cancer Persian Gulf sea cucumber species Holothuria arenicola (H. arenicola) aqueous extract on mice colon carcinoma cells in vitro and in ...
Poly(ADP-ribose) polymerase-1 (PARP-1) which mediates poly-ADP-ribosylation, has been extensively investigated in carcinoma compared to arginine ADP-ribosyltransferase 1 (ART1), which mediates mono‑ADP‑ribosylation. Previous studies have demonstrated that these enzymes promote proliferation and tumor development in colon carcinoma. However, whether there is any association between PARP-1 and AT...
BACKGROUND β-Lapachone is a quinone-containing compound found in red lapacho ( Tabebuia impetiginosa, syn. T avellanedae) trees. Lapacho has been used in traditional medicine by several South and Central American indigenous people to treat various types of cancer. The purpose of this study was to investigate the antimetastatic properties of β-lapachone and the underlying mechanisms using colon ...
Boron neutron capture therapy (BNCT) was performed at the University of Missouri Research Reactor in mice bearing CT26 colon carcinoma flank tumors and the results were compared with previously performed studies with mice bearing EMT6 breast cancer flank tumors. Mice were implanted with CT26 tumors subcutaneously in the caudal flank and were given two separate tail vein injections of unilamella...
BACKGROUND Anticancer drugs act by increasing intracellular hydrogen peroxide levels. Mangafodipir, a superoxide dismutase (SOD) mimic with catalase and glutathione reductase activities, protects normal cells from apoptosis induced by H2O2. We investigated its and other oxidative stress modulators' effects on anticancer drug activity in vitro and in vivo. METHODS Cell lysis and intracellular ...
BACKGROUND Gold-polyamidoamine (AuPAMAM) has previously been shown to successfully transfect cells with high efficiency. However, we have observed that certain cell types are more amenable to Au-PAMAM transfection than others. Here we utilized two representative cell lines-a "difficult to transfect" CT26 cell line and an "easy to transfect" SK-BR3 cell line-and attempted to determine the underl...
UNLABELLED Many solid tumors overexpress EphB4 receptor, a member of the ephrin receptor tyrosine kinase family. Noninvasive imaging of EphB4 could potentially increase early detection rates, monitor response to therapy directed against EphB4, and improve patient outcomes. The purpose of this study was to evaluate a novel (64)Cu-labeled peptide with high receptor binding affinity for PET of Eph...
AIM To elucidate the role of proton pump inhibitors (PPIs) in collagenous disease, direct effect of PPI on colonocytes was examined. METHODS Collagenous colitis is a common cause of non-bloody, watery diarrhea. Recently, there has been increasing focus on the use of proton PPIs as a risk factor for developing collagenous colitis. Mouse CT26 colonic cells were treated with PPI and/or PPI-induc...
