celecoxib is a non-steroidal anti-inflammatory drug (nsaid) developed as a selective inhibitor of cyclooxygenase-2 (cox-2) for the treatment of rheumatoid arthritis disease. recently some other mechanisms have been identified for anti cancer activity of these agents including induction of apoptosis, inhibition of tumor vascularization, stimulation of antitumor immune responses and inhibition of...

a multiple colorimetric assay has been introduced to evaluate the proliferation and determination of survival fraction (sf) of irradiated cells. the estimation of sf based on the cell‑growth curve information is the major advantage of this assay. in this study, the utility of multiple‑mts assay for the sf estimation of irradiated ht‑29 colon cancer cells, which were plated before irradiation, w...

Colorectal cancer (CRC) is one of the most common reasons for cancer-associated mortality worldwide. The present study aimed to investigate the drug resistance mechanism of the oxaliplatin (OXA)-resistant HT-29 cell line (HT-29/L-OHP) and examine the expression of lysosome-associated protein transmembrane 4β (LAPTM4β), a drug resistance-associated gene. In the present study, a drug concentratio...

Background: Lactobacillus and Bifidobacterium species are among the probiotics discussed due to their anti-cancer effects in the treatment of colorectal and breast cancers in recent studies. The aim of this study was to investigate the anticancer effect of Familact, a commercial probiotic capsule containing seven bacterial strains (L. casei, L. acidophilus, L. rhamnosus, L. bulgaricus, B. breve...

A new series of N-(5-Mercapto-1,3,4-thiadiazol-2-yl)-2-phenylacetamide derivatives (3a-3j) were synthesized via an amidation reaction using EDC and HOBt in acetonitrile solvent at room temperature condition. Chemical structures were characterized by 1H NMR, IR and MS spectroscopic methods and related melting points were also determined. The anticancer activity was evaluated using MTT procedure ...

Evidence has suggested that salidroside inhibits the proliferation and invasion of renal clear cell, lung, breast, and colon cancer. However, effect of salidroside on colorectal cancer (CRC) cells against oxaliplatin (L‑OHP) resistance remains unclear. In the present study, the CRC HT‑29 cell line and L‑OHP resistance HT‑29/L‑OHP cell line were used to evaluate the effect, and mechanism of sali...

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...

Introduction: Radiation therapy is an important procedure for treatment of more than half of tumors. One way to increase the efficiency of radiation therapy is application of radiosensitizer at the site of tumor. gold nanoparticles (GNPs) have several characteristics that make them attractive for using with radiation therapy including small size (1–100 nm), biocompatibility, pr...
