Hylomecon vernalis Maxim. has traditionally been used to promote blood circulation, alleviate pain, dissipate stasis, and reduce swelling. The aim of the present study was to investigate the effect and potential mechanism of H. vernalis Maxim. ethanol extracts (HVMEE) on the growth and apoptosis of human colon cancer HT‑29 and SW620 cells. H. vernalis samples were extracted three times with eth...

Investigations on the cytotoxic effects of the crude methanol and fractionated extracts (hexane, ethyl acetate) C. mangga against six human cancer cell lines, namely the hormone-dependent breast cell line (MCF-7), nasopharyngeal epidermoid cell line (KB), lung cell line (A549), cervical cell line (Ca Ski), colon cell lines (HCT 116 and HT-29), and one non-cancer human fibroblast cell line (MRC-...

Hedyotis diffusa Willd (HDW) has long been used as an important component in several Chinese medicine formulae to clinically treat various types of cancer, including colorectal cancer (CRC). Previously, we reported that HDW inhibits CRC growth via the induction of cancer cell apoptosis and the inhibition of tumor angiogenesis. In the present study, to further elucidate the mechanism of HDW-medi...

cancer is a major cause of death worldwide and causes serious problems in human life. it is developed by uncontrolled growth of a cell or a group of cells. there are many difficulties in treatment of cancer and many researchers are involved in investigating for effective drugs to treat the disease. caryophyllaceae is a large family of about 86 genera and 2200 herbaceous or subshrub species. the...

OBJECTIVE Lactobacilli are a group of probiotics with beneficial effects on prevention of cancer. However, there is scant data in relation with the impacts of probiotics in late-stage cancer progration, especially metastasis. The present original work was aimed to evaluate the anti-metastatic and anti-proliferative activity of lactobacillus rhamnosus supernatant (LRS) and lactobacillus crispatu...

Background & Aims: In most cases, drugs used for the treatment of cancer are not effective or have unpleasant side-effects. This has forced scientists to find more effective drugs with less toxicity. Artemisia is an important medicinal plant in the world and anti-tumoral activity of some Artemisia species has been reported. This study was designed for evaluation of anti-tumoral effect of methan...

Introduction: In the point of physical view, there are no significant differences between tumor and normal tissues during radiation therapy. Radio-sensitizers have a key role to address the issue. Exploiting high atomic number, gold nanoparticles (GNPs) have been introduced as novel radio-sensitizers and have shown promising result in the field. Owing to high mass attenuation c...

Docetaxel (Taxotere, DTX) is a promoter of apoptosis in cancer cells. Since cytotoxic mechanisms of DTX are not yet fully understood, we have investigated the effects of DTX on apoptosis and ras-->Erk-mediated signal transduction in human epidermoid KB, colon HT-29 and breast HCC1937 cancer cells. We have found that the exposure to 0.78 or 1.56 or 2.5 ng/ml DTX for 48 h induced apoptosis and gr...

Previous report showed that epidermal growth factor (EGF) promotes tumor progression. Several studies demonstrated that growth factors can induce heme oxygenase (HO)-1 expression, protect against cellular injury and cancer cell proliferation. In this study, we investigated the involvement of the c-Src, NADPH oxidase, reactive oxygen species (ROS), PI3K/Akt, and NF-κB signaling pathways in EGF-i...

BACKGROUND Achaete scute-like 2 (Ascl2), a basic helix-loop-helix (bHLH) transcription factor, controls the fate of intestinal stem cells. However, the role of Ascl2 in colon cancer progenitor cells remains unknown. The cell line HT-29 (47.5-95% of CD133(+) population) and LS174T (0.45% of CD133(+) population) were chosen for functional evaluation of Ascl2 in colon cancer progenitor cells after...
