Rhizochalin is a two-headed sphingolipid-like compound isolated from the sponge Rhizochalina incrustata. It has been reported that rhizocalin and its derivates have a chemopreventive and chemotherapeutic effect. However, the molecular mechanism of these effects is not understood. Here, we demonstrate that aglycon of rhizochalin (AglRhz) from the Rhizochalina incrustata induces AMP-activated pro...

Introduction Dentatin (DEN) (5-methoxy-2, 2-dimethyl-10-(1, 1-dimethyl-2propenyl) dipyran-2-one), a natural compound present in the roots of Clausena excavata Burm f, possesses pro-apoptotic and antiproliferative effects in various cancer cells. Because of its hydrophobicity, it is believed that its complexation with hydroxy-β-cyclodextrin (HPβCD) will make it a potent inhibitor of cancer cell ...

Adjuvant use of safe compounds with anti-tumour properties has been proposed to improve cancer chemotherapy outcome. We aimed to investigate the effects of fish oil emulsion (FOE) rich in n-3 PUFA with the standard chemotherapeutic agents 5-fluorouracil (5-FU), oxaliplatin (OX) or irinotecan (IRI) on two human colorectal adenocarcinoma cells with different genetic backgrounds. The HT-29 (Bax+/+...

Oxaliplatin (L-OHP) is standard treatment for colorectal cancer. However, resistance to L-OHP often leads to treatment failure or cancer relapse. Understanding of the mechanism underlying L-OHP resistance is important to overcome the resistance and improve colorectal cancer treatment. This study aimed to identify new proteins that mediates L-OHP resistance in colorectal cancer and elucidate the...

The Houttuynia cordata Thunb (HCT) extract has been used as a traditional Chinese herb medicine and as well as an effective drug for treating allergic inflammation for thousands of years. In this study, we investigated the anti-cancer activity of HCT and its molecular mechanisms in the human colon adenocarcinoma cell line HT-29. HCT inhibited HT-29 cell viability in a dose- and time-dependent m...

Colorectal cancer (CRC) is considered one of the leading types in world. CD133, as a stem cell marker, has pivotal role development drug resistance, migration, and stemness properties CRC cells. This study was designed to check combined effect CD133 siRNA Oxaliplatin on proliferation, apoptosis, cells HT-29 line. MTT assay performed define viability cells, it showed that combination could reduc...

Massively increasing global incidences of colorectal cancer require efficient treatment and prevention strategies. Here, we report unexpected anticancerogenic effects of hydroethanolic Iberis amara extract (IAE), which is known as a widely used phytomedical product for treating gastrointestinal complaints. IAE significantly inhibited the proliferation of HT-29 and T84 colon carcinoma cells with...

The role of mitogen-activated protein kinase (MAPK) signaling pathways in cell growth and differentiation has been well established. The present study aimed to investigate the anti-proliferative effect of stevioside on human colon cancer HT-29 cells. Additionally, the effect of stevioside on cell cycle arrest and MAPK signaling pathways in HT-29 cells was explored. Stevioside was observed to si...

AIMS AND BACKGROUND Colorectal cancer is one of the commonest cancers. Chemoradiotherapy gives better results than radiotherapy or chemotherapy in colorectal cancer. To enhance radiosensitivity of tumor cells for chemoradiotherapy, targeted therapy drugs that act as radiosensitizers can be used. In the present study, we provide a scientific rationale for the clinical application of sorafenib as...
