Abstract

Novel effective chemopreventive agents against cancer are required to improve current therapeutic rates. The aim of the present study was to investigate the anti-carcinogenesis effect of AntiGan, an extract obtained from the European conger eel, Conger conger, in vitro (human tumor cell lines) and in vivo (murine model of colitis) models. The potential apoptogenic activity after 24 h of incubation with 10, 25 and 50 µl/ml AntiGan was reported using growth inhibition and apoptosis activity assays. In vivo studies were performed in mice by inducing colitis with oral administration of 2% dextran sulphate sodium (DSS) for 5 weeks. Apoptosis was observed in HL-60, Hs 313.T, SW-480, Caco-2 and HT-29 cell lines. The highest level of growth inhibition was observed in Caco-2 (66, 75.8 and 88.1%), HT-29 (56, 73 and 87.6%) and SW-480 (38.5, 61.6, 78.6%) for AntiGan doses of 10, 25 and 50 µl/ml, respectively, compared to untreated cells, while the results of the expression of genes associated with apoptosis indicated a downregulation of B-cell lymphoma 2 (Bcl-2) in all cell lines studied. In vivo, morphopathological alterations in the colon were analyzed by immunohistochemical and staining methods. Tumoral markers, including β-catenin, cyc...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins. Discover the latest research on cadherins and catenins here.
