Several monoclonal antibodies were raised against the human epidermoid carcinoma line A 431. The antibody produced by clone AR-3, when tested in enzyme-linked immunosorbent as say, was found to react with the cell line used as immunogen, the human gastric carcinoma line KATO III, the colon carcinoma line HT29, and the ovarian carcinoma line SW626. This monoclo nal antibody was found unreactive ...

medicinal plants have been investigated for possible anti-cancer effects. the aim of the present study was to examine the cytotoxic activity of several medicinal plants on different tumor cell lines. 11 selected plant species which have been used in folkloric prescriptions were collected from different sites of hamedan district of iran. the methanolic extracts of the plants were prepared and th...

  Objective(s):Transforming growth factor-β(TGF-β) is involved in colorectal cancer (CRC). The SD-208 acts as an anti-cancer agent in different malignancies via TGF-β signaling. This work aims to show the effect of manipulation of TGF-β signaling on some miRNAs implicated in CRC. Materials and Methods: We investigated the effects of SD-208 on SW-48, a colon adenocarcinoma cell line. The cell li...

BACKGROUND Vincristine (VCR) is a chemical that is widely used in tumor therapy. While long-term use can make tumor cells resistant to VCR, the underlying mechanisms of this resistance are still unclear. OBJECTIVE This study aimed at investigating the role of microRNA (miRNA) in colon cancer drug resistance. METHODS HCT-8 colon carcinoma cells were cultured and treated with different VCR co...

Background/Aim: Salvadora persica is an evergreen shrub or small tree to 6-7m. Fruits have a sweet, agreeable, aromatic, slightly pungent and peppery taste. It has many biological activities such as antipyretic, anti-inflammatory and antifungal activities. This study aims to evaluate cytotoxic effect of Salvadora persica, meswak, (Salvadoraceae) extracts and isolate main compounds from the most...

A line of human colon carcinoma cells, designated MOSER, was established which synthesized tumor-inhibitory factor (TIF) and transforming growth factor (TGF) activity. Both activities were found in serum-free conditioned medium and in cell extracts. The activities coelute on Bio-Gel P-10 in acetic acid, but can be completely separated by reverse-phase high-pressure liquid chromatography. The TI...

IDH2 encodes a mitochondrial metabolic enzyme that converts isocitrate to α-ketoglutarate (α-KG) by reducing nicotinamide adenine dinucleotide phosphate (NADP(+)) to NADPH and participates in the citric acid cycle for energy production. Notably, this gene has been shown to be critical for cell proliferation. The abnormal expression of IDH2 has been reported in several types of cancer, and mutat...

slug (snai2), a regulator of epithelial-to-mesenchymal transition (emt), is a zinc finger transcription factor involved in neurulation. intriguingly, snai2 gene expression has been linked to the aggressiveness of neuroblastoma, melanoma and lung, colon, ovarian and breast carcinoma. of note, many metastatic cancers recapitulate emt to enhance cell motility and invasion. moreover, metastasis is ...

The history of immunizing with embryonic materials to generate an antitumor immune response dates back to a century ago. The premise is that cancer cells share the expression of oncofetal antigens with embryonic materials and that the immune response against these antigens in the embryonic tissues is cross-protective against cancer. However, such a practice has never advanced beyond experimenta...

objective(s):transforming growth factor-β(tgf-β) is involved in colorectal cancer (crc). the sd-208 acts as an anti-cancer agent in different malignancies via tgf-β signaling. this work aims to show the effect of manipulation of tgf-β signaling on some mirnas implicated in crc. materials and methods: we investigated the effects of sd-208 on sw-48, a colon adenocarcinoma cell line. the cell line...
